Abstract<\/h3>\n

This study examines the effectiveness of a fully online flipped classroom (FC) supported by an Interactive Response System (IRS) in enhancing vocabulary learning among low-proficiency EFL learners. Addressing the limited research on IRS-integrated online FC models for vocabulary instruction, the study compares a traditional paper-based FC with an online IRS-based FC. A two-cycle classroom action research design was implemented with 46 first-year students at an Indonesian Polytechnic, targeting 300 items from the Academic Word List. In Cycle 1, students engaged with paper-based materials in an offline FC environment, while Cycle 2 involved online vocabulary learning using various IRS platforms. Vocabulary outcomes were measured through a pretest and two posttests and analyzed using paired t-tests. Results indicate that although both FC models significantly improved learners\u2019 vocabulary scores, the online IRS FC yielded substantially greater gains. Thematic analysis of students\u2019 open-ended responses showed that both approaches promoted engagement; however, the paper-based FC was perceived as monotonous and tiring, while the online IRS FC presented challenges related to unstable internet access and learning anxiety. The findings highlight the pedagogical potential of integrating IRS platforms into online flipped classrooms to strengthen vocabulary learning and inform instructional design in technology-enhanced EFL contexts.<\/p>\n

The swift advancement of technology has transformed the educational landscape by enhancing its accessibility and personalization, which provide effective and meaningful learning opportunities (Oguguo et al., 2020), connecting students to wider knowledge transfer (Hehir et al., 2021), enhancing students\u2019 transversal skills (Niemi et al., 2024), and enriching their educational experiences (Al-Labadi & Sant, 2021). One example of the rapid development of technology in education is the emergence of the flipped classroom. Many studies yield on flipped learning due to its virtues in fostering self-paced, collaborative learning, deepening conceptual understanding, enhancing learning skills, positively impacting students’ learning, focusing on student-centered learning, encouraging self-efficacy, developing independent thinking, creating active engagement, and improving learning outcomes (Aidoo et al., 2022; Dusengimana et al., 2023; W. Han & Hamzah, 2024; Putri et al., 2024). In the context of vocabulary learning, the flipped classroom offers opportunities to enhance students\u2019 engagement (Pratiwi et al., 2024), improve students\u2019 vocabulary gains (Yang et al., 2019), and develop students\u2019 self-directed learning (Anggoro & Khasanah, 2022).<\/p>\n

In the implementation of the flipped classroom, the integration of technology and educational platforms, such as an Interactive Response System (IRS), has the potential to enhance the entirely online flipped classroom. IRS, which provides real-time feedback and interaction, contributes to English learning ecology by fostering engagement, promoting focus, boosting motivation through interactive and challenging activities, leading to more meaningful learning experiences, and assisting students\u2019 learning (Anggoro & Pratiwi, 2023b; Sun & Hsieh, 2018); Various IRS platforms can be utilized to scaffold and support students\u2019 vocabulary learning, such as Quizizz, Quizlet, Socrative, Pear Deck, Magoosh Vocabulary Builder, Kahoot!, Quizlet, Memrise, Vocablet, Wordle<\/em>, etc.<\/p>\n

There has been a growing interest in conducting studies on online flipped classrooms in many educational contexts (Althubaiti & Althubaiti, 2024; Dermentzi, 2024; Domu et al., 2023; Gok et al., 2023; Marshall & Kostka, 2020; Widodo, 2022; Xu et al., 2023). The online class facilitated students’ participation in outside-class activities, while in-class activities were conducted in a face-to-face manner. However, there is a lack of studies, particularly those exploring the utilization of a fully online flipped classroom integrating an Interactive Response System for vocabulary learning. This current study attempts to investigate this gap by exploring online flipped classrooms in relation to students\u2019 vocabulary learning.<\/p>\n

Research Objectives<\/h4>\n

The present study intends to add knowledge to the literature by exploring the extent to which an Interactive Response System (IRS) can facilitate vocabulary learning in a fully online flipped classroom environment. It seeks to compare the implementation of a traditional paper-based and online IRS flipped classroom to enhance academic vocabulary learning. The following questions are raised:<\/p>\n

    \n
  1. What are students\u2019 vocabulary learning outcomes in a fully online IRS flipped classroom?<\/li>\n
  2. What are the impacts of implementing a fully online IRS flipped classroom in vocabulary learning?<\/li>\n<\/ol>\n

    Literature Review<\/h3>\n

    The flipped classroom, the basic framework of the present study, was discussed comprehensively to provide a broader insight into the learning model. It explained the general concept of the flipped classroom and both models \u2013 traditional and online. Further, vocabulary learning integrated with IRS platforms was reviewed to add a comprehensive theoretical framework underlying the study.<\/p>\n

    General Concept of Flipped Classroom<\/h4>\n

    Teachers were long tasked with finding a method to cater to the diverse demands of their students. Personalizing education has been suggested as a remedy in this scenario. Teachers have been instructed to deliver a customized education for every student, and the majority of them view personalization as a beneficial objective for each student. Yet, the administrative burden of customizing numerous educational experiences regularly appears overwhelming to many teachers. Personalization can be challenging for many teachers, leading them to adopt a broad teaching method that presents a large amount of knowledge to reach as many learners as possible. Those reflections were written in a book entitled \u201cFlipped Your Classroom: Reach Every Student in Every Class Every Day\u201d (Bergmann & Sams, 2013), based on the teaching experiences of Jonathan Bergmann and Aaron Sams in chemistry and advanced chemistry lectures.<\/p>\n

    Drawing from such urgent conditions, both began to implement the flipped classroom model by recording their lectures in video format from 2007 to 2008. They uploaded the video to the internet, and then the students viewed it as part of their homework. Subsequently, they dedicated the entire class session to assisting students with the subjects they struggled to grasp. They were very pleased with their students\u2019 learning after implementing the model for a year of lectures. They had evidence to show how the flipped classroom model worked and was beneficial for students. Clearly, this strategy proved to be more efficient than traditional methods such as teaching and distributing homework. The students acquired additional knowledge and obtained preliminary data suggesting that the flipped classroom was more effective than the usual approach. They claimed that flipping the classroom created a structure that guaranteed students would receive an academic experience tailored to their specific needs. The model enabled teachers to effectively personalize the education of each student.<\/p>\n

    In the development, the flip model is derived from the acronym F-L-I-P, which stands for a flexible environment, a learning culture, intentional content, and professional educators (Marshall & Kostka, 2020). A flexible environment pertains to the shift in learning dynamics when students take greater control over how and where they take part in learning, rather than the teacher being the primary focus in the traditional classroom setting. Learning culture emphasizes the transition from teacher-centered to student-centered instruction, focusing on active learning, feedback, and scaffolding. The intentional content emphasizes the instructors\u2019 responsibility in assisting learning, developing, and organizing pertinent content to aid learning outside the classroom. As an expert instructor, the teacher establishes an adaptable learning setting, administers frequent formative evaluations within and outside of class, and collaborates with colleagues to exchange ideas and contemplate teaching practices. This model accentuates the transition from teacher-centered to student-centered instruction and emphasizes the significance of active learning by referring to the method and setting in which students participate in learning, besides the physical classroom (Pratiwi et al., 2022, 2024).<\/p>\n

    Flipped Classroom: Traditional and Online Model<\/h4>\n

    The progress of science and technology in the era of Society 5.0 has inspired many learning innovations. The \u201cwhat to learn\u201d approach has become obsolete and has been replaced by the \u201chow to learn\u201d approach. Accordingly, the innovation affects the \u201chow to learn\u201d of the flipped classroom model. The \u2018traditional\u2019 flipped classroom, which utilized video as the early model, developed into Website material, PDF material, and audio listening. Gamification can also facilitate the flipped classroom model due to its growing interest and positive impacts on student learning experience and outcomes. However, the reliance on technology and internet issues has become a significant challenge in the implementation of the flipped classroom (S. Han, 2022). To overcome these challenges, schools can provide access to technology resources and offer training sessions to ensure students and parents are comfortable using the technology.<\/p>\n

    Furthermore, teachers can offer alternatives like providing physical resources in a paper-based method (Pratiwi et al., 2024). Flipped learning is a teaching method where direct instruction is done individually, allowing the group learning space to become an interactive environment where the educator assists students in applying concepts and engaging creatively with the subject matter (Bergmann & Sams, 2013). Flipping a class may result in flipped learning, but it is not guaranteed to do so. Some teachers may already implement aspects of flipped learning by assigning readings, films, or extra tasks for students to complete outside of class. However, for students to succeed in a flipped learning environment, teachers need to integrate the four essential components of the flipped classroom into their practice.<\/p>\n

    Patel (2021) argues that paper is a crucial educational tool as it offers a physical surface for students to structure and document their ideas, information, and innovation. According to the findings, students chose to write by hand since it assisted them in remembering the information that they had studied. In addition, paper has the potential to make it simpler for students to recognize and comprehend, and aid students in establishing a higher degree of active involvement and participation. Zhao and Watterston (2021) claim that students have the ability to engage with paper-based materials in a more profound manner than they would be enabled to do with content that is solely digital if they were able to grasp and touch the materials physically.<\/p>\n

    \"Traditional
    \nFigure 1. Traditional Flipped Classroom with Paper-based Method<\/strong><\/p>\n

    Gamified technology, as part of an Interactive Response System in a flipped classroom setting, employs a flipped classroom concept that utilizes games to enhance student learning. In order to inspire players to engage in an activity that they would not find appealing in any other circumstance, the learning process entails the utilization of game components, such as incentive systems (Plass et al., 2015). Lam et al. (2023) argue that the game enhances the opportunity for users to learn in authentic environments. Therefore, the game-based method is implemented for delivering material in pre-class sessions, discussing unclear material, and completing assignments in class time. This method is appropriate for schools and students, and it provides complete support for technological devices, including computers or laptops, mobile phones or tablets, and an internet connection. Utilizing game design elements in education is intended to create more captivating and enjoyable learning settings (Waluyo & Bucol, 2021). In the same vein, gamification is defined as a strategic technique that utilizes game design ideas to establish an engaging and dynamic learning setting (Pratiwi & Waluyo, 2022).<\/p>\n

    \"Online
    \nFigure 2. Online Flipped Classroom with Interactive Response System<\/strong><\/p>\n

    Research has indicated that the implementation of a flipped classroom has received positive feedback from students in the EFL setting (Johnson, 2013; Pratiwi et al., 2024; Talan & Gulsecen, 2019). Pratiwi and Waluyo (2022) argued that technology has the potential to provide a learning environment where students can learn at their own speed and effectively achieve mastery. Furthermore, educators implementing the flipped classroom approach have the ability to incorporate supplementary components such as formative evaluations, inquiry-based problem-solving activities, and methods for accommodating diverse learning needs. This enables them to establish a more adaptable instructional environment compared to conventional classroom settings (Pratiwi et al., 2022). Johnson (2013) found out that students in a flipped classroom complete less homework assignments compared to students in a typical lecture-based classroom. However, students find the learning experience enjoyable in a flipped classroom environment.<\/p>\n

    Furthermore, students derive benefits from watching their lectures in shortened lesson videos. Similarly, Pratiwi et al. (2024), and Talan and Gulsecen (2019) stated that the learners expressed happiness with the implementation of the flipped classroom framework in the EFL context. Consequently, teachers have to pay attention to students\u2019 characteristics and needs before implementing the learning model in their EFL classroom (Pratiwi & Waluyo, 2022; Waluyo & Bucol, 2021). However, Teng (2017) argued that due to an overwhelming amount of learning materials in today\u2019s EFL learning, flipped learning can be a solution to this. Accordingly, the flipped classroom has been receiving increased attention at all levels of education(Anggoro & Khasanah, 2022; Arifani et al., 2020; Phoeun & Sengsri, 2021).<\/p>\n

    Vocabulary Learning Utilizing Interactive Response System (IRS)<\/h4>\n

    According to Teng and Reynolds (2024), acquiring vocabulary is not merely the act of memorizing a set of words but rather an intricate and prolonged undertaking. It requires continual exercise to strengthen learners\u2019 innovative thinking, cognitive processes, communicative proficiency, and ability to infer meaning from context. For instance, we have all encountered the phenomenon of being able to comprehend and identify a word when encountering it in written form or hearing it in a discussion, yet lacking the ability to employ it oneself (Webb & Nation, 2017). Due to the complexity of the learning process, various strategies may be suitable at different stages of the gradual learning process, and learners must possess extensive lexicons in order to utilize a second language effectively; therefore, it is imperative to establish and strive for ambitious vocabulary goals (Schmitt, 2019). Instructors deliberately promote beneficial vocabulary, and unfamiliar words are frequently taught when they arise.<\/p>\n

    Research in Japanese university EFL classrooms revealed that the students positively perceived vocabulary learning using a paper-based method through simplified pictures (Bates & Son, 2020). In the context of learning and teaching English vocabulary through a paper-based method, it has been claimed that simple visual forms have the potential to serve as an alternate and supplementary option. Graphical representations, such as diagrams, drawings, and photographs, should be abundant in textbooks. This will make the content more engaging and easier to absorb, ultimately helping students improve their comprehension of foreign languages. In the same vein, a study in Saudi Arabian EFL classrooms found that students had more positive attitudes toward the use of image-associative methods in language classrooms than toward video or audio-associative methods (Alhamami, 2016). Further, Gallegos (2021) identified the impact of utilizing flashcards as a novel approach to enhance the acquisition and comprehension of English language vocabulary through a traditional paper-based method. The findings indicated that the use of flashcards had a beneficial impact on the acquisition of new vocabulary and, hence, on language learning as a whole. Some research findings have shown less effectiveness in paper-based vocabulary learning compared to digital vocabulary learning (Ahmadian, 2015). The findings demonstrated that the contextualization of the words through the use of a computer had a more significant impact on vocabulary acquisition than the contextualization of the words through the use of paper.<\/p>\n

    There is a belief that incorporating an IRS through gamified technology platforms into vocabulary learning can effectively improve language acquisition by facilitating quicker and easier vocabulary acquisition for learners (Gokbulut, 2020; Wardoyo et al., 2021). IRS vocabulary learning serves as a method to engage and stimulate students’ interest in learning words within a playful framework, while still providing comprehensive vocabulary training. A high-quality vocabulary game provides players with the opportunity to learn in meaningful and applicable situations, where crucial information is delivered promptly and aligned effectively with gamers’ preferences (Qin & Hua, 2020). Vocabulary learning through gamification has transitioned to digital technologies that make use of Computer-Assisted Language Learning (CALL) and Mobile-Assisted Language Learning (MALL) in the form of IRS. Empirical research has demonstrated that interactive response system platforms are suitable for fulfilling both students’ requirements in vocabulary learning and teachers\u2019 requirements in facilitating vocabulary learning, including Google Forms, Socrative, Kahoot!, Quizizz, <\/em>and Quizlet<\/em> (Anggoro, 2021; Rofiah & Waluyo, 2020). In the same vein, Wu et al. (2025) suggested that collaborative interactions in gaming can significantly enhance learner engagement by necessitating precise actions, effective communication, and emotional investment, thereby facilitating a deeper connection with the language being learned. Acquiring vocabulary via IRS enhances class participation beyond conventional classroom environments, incorporating digital platforms where behavioral, cognitive, and affective factors interact dynamically.<\/p>\n

    Research Methodology<\/h3>\n

    This part outlined the methodology employed in the current study, which comprised five primary components: 1) research design, 2) contexts and participants, 3) research procedures, 4) data collection and instruments, and 5) data analysis.<\/p>\n

    Research Design<\/h4>\n

    The present study employed a two-cycle classroom action research design. Action research emphasizes the benefits of action in research for improving practice and adopting an integrated approach to learning, as opposed to a single-subject style of teaching and learning (Cohen et al., 2017). In education, action research is manifested when teachers implement several changes to their teaching practices in an attempt to address emerging problems in the classroom and among their learners (Waluyo & Bakoko, 2021). Therefore, this study focused on exploring the effectiveness of using paper-based materials in a traditional flipped classroom compared to IRS materials in an online flipped classroom to teach vocabulary.<\/p>\n

    In the first cycle, the learners were taught using paper-based vocabulary materials in the traditional flipped classroom environment. In the second cycle, the learners were taught using gamified vocabulary materials in the online flipped classroom setting. The study lasted for 13 weeks, during which each cycle consisted of a 5-week teaching-learning process and 3 weeks for conducting pretest and posttest. Following the posttests, online open-ended surveys were distributed to the students to gather their thoughts and comments on the vocabulary learning model in each cycle.<\/p>\n

    Context and Participants<\/h4>\n

    The study was conducted in the 2nd<\/sup> semester of the 2023\/2024 academic year at an Indonesian Polytechnic. As a single-subject study in action research design, this study utilized a purposive sampling method. The participants were first-year students in the Railway Mechanical Technology study program, comprising 46 students. They enrolled in General English II with proficiency at a low level (under 70 out of 100 points), which was equivalent to basic users in the Common European Framework of Reference for Languages (CEFR). Ranging in age from 18 to 20 years old, all participants were informed and agreed to participate in the research, and the results did not affect their scores.<\/p>\n

    Research Procedure<\/h4>\n

    General English II was an integrated English subject that encompassed listening, reading, structure, vocabulary, and writing. There were 16 meetings in a semester, including mid-semester and final-semester tests \u2013 the teaching and learning process lasted for 14 meetings. Each meeting lasted for 150 minutes. The vocabulary learning used in this study spanned 13 sessions, each with a duration of approximately 30 minutes. Since the present study implemented the flipped classroom model, the material was provided as pre-class activities outside the classroom one week prior to the start of class (see Table 1). In the first cycle, the activities were conducted using a face-to-face model with paper-based materials. In the second cycle, the activities were held fully online through a Zoom meeting, utilizing several Interactive Response System (IRS) platforms, including Quizlet, Quizzes, Kahoot!,<\/em> and Socrative.<\/em><\/p>\n

    In the 1st<\/sup> week, a pretest was administered to determine students\u2019 basic vocabulary knowledge. After completing the pretest, students received vocabulary paper-based material as a pre-class activity for the 2nd<\/sup> meeting. The students had to fill out a table that consisted of parts of speech, their meanings, and corresponding sentences. During offline class activities, the task was discussed, and synonyms and antonyms of the word were listed. The pre-class materials were delivered after the in-class activities were finished. The activities were repeated till the 6th<\/sup> week. In the 7th<\/sup> week, a posttest (posttest 1) was administered to measure students\u2019 learning outcomes of vocabulary learning utilizing paper-based materials in the traditional flipped classroom environment. After the posttest, a student survey was distributed to collect their opinion on the paper-based method in the face-to-face flipped classroom environment.<\/p>\n

    At the end of the seventh week, students were provided with a link to access the 6th<\/sup> vocabulary set material on Quizlet<\/em> as pre-class tasks. On the platform, they can self-directed learning through flashcards, learn, test, and match. In the 8th<\/sup> week, the students discussed the materials through several IRS platforms such as Quizizz, Kahoot!,<\/em> and Socrative. <\/em>After finishing the in-class activities, the pre-class activity link for the next meeting was delivered. The activities were repeated till the 12th<\/sup> week. In the 13th<\/sup> week, the students did a posttest (posttest 2) as vocabulary evaluation to find out students\u2019 vocabulary learning outcomes utilizing IRS platforms through gamified technology applications in the online flipped classroom setting. The students\u2019 survey to collect their opinions toward the IRS in the fully online flipped classroom environment was distributed after the posttest.<\/p>\n

    The material for vocabulary learning was drawn from the Academic Word List (AWL), which comprises scientific vocabulary consisting of context-independent formal words with high frequency and a wide range of occurrence across various scientific disciplines (Dizon, 2016). It was purported to encompass vocabulary often found in academic books, making it a valuable gauge of learners\u2019 academic proficiency (Gholaminejad & Sarab, 2021). The present study selected 300 words from AWL and delivered 30 words per week to the students. (Table 2)<\/p>\n

    Data Collection and Instruments<\/h4>\n

    The data for the study were gathered from the results of pretest, posttests, and students\u2019 surveys. The pretest was conducted at the beginning of the class (1st<\/sup> week) to assess students\u2019 prior vocabulary knowledge. The posttests were performed twice: after the 1st<\/sup> cycle (7th<\/sup> week) and after the 2nd<\/sup> cycle (13th<\/sup> week). Both pretest and posttest were adapted from previous research conducted by Pratiwi et al. (2024). To assess vocabulary knowledge, there were 50 multiple-choice questions consisting of synonyms, antonyms, definitions, sentence completion, and parts of speech. Despite acknowledging the limitations of the multiple-choice format in fully capturing vocabulary proficiency, particularly in contextual application, it was utilized for its standardized and efficient data collection capabilities. All tests had different questions, but they shared the same aspects and qualities.<\/p>\n

    \"Pretest
    \nFigure 5. Pretest and Posttest Sample Questions<\/strong><\/p>\n

    The survey was conducted to gather students\u2019 opinions about vocabulary learning in a flipped classroom environment, using each learning method. It was in an open-ended questionnaire distributed online through Google Forms. <\/em>Their comments were anonymous, allowing students to express their thoughts freely. The survey results were used to support the quantitative data, providing comprehensive insights into the vocabulary teaching method.<\/p>\n

    Data Analysis<\/h4>\n

    The data analysis involved two sets of data: students\u2019 vocabulary test scores (quantitative) and survey results (qualitative). The quantitative data were analyzed in SPSS using descriptive statistics and correlation analysis (paired sample t-test), while the qualitative data utilized content analysis to support the quantitative findings. The results of the data analysis were triangulated to answer research questions about the impact of the traditional flipped classroom, utilizing the paper-based method, and the online flipped classroom, utilizing the interactive response system.<\/p>\n

    Results and Discussion<\/h3>\n

    Students\u2019 Vocabulary Learning Outcomes<\/h4>\n

    The results of descriptive statistics analysis in Table 3 showed that students\u2019 learning outcomes improved from pretest to posttest 1 and posttest 2. Posttest 1 resulted from vocabulary scores at the 1st<\/sup> cycle, which employed the paper-based method in the face-to-face flipped classroom environment. Posttest 2 was the result of vocabulary scores at the 2nd<\/sup> cycle, which utilized the interactive responses system in the online flipped classroom environment. The Skewness<\/em> and Kurtosis<\/em> values indicated that the data was normally distributed, as the results fell within the range of -2 to +2. Therefore, the data fulfilled the assumptions for a paired sample t-test analysis.<\/p>\n

    The correlation was moderate for all paired test, yet the effect size was different. The effect size for the pretest and posttest of the offline paper-based flipped classroom was moderate, whereas the paired sample t-test between the pretest and posttest of the online IRS flipped classroom had a large effect size. This meant that traditional paper-based and fully online IRS flipped classrooms effectively boosted students\u2019 vocabulary learning outcomes. Specifically, the mean differences showed that the fully online IRS flipped classroom received higher scores on their Pre-Post test (1) than the offline paper-based flipped classroom Pre-Post test (2).<\/p>\n

    Comparing the offline paper-based flipped classroom posttest and the online IRS flipped classroom posttest yielded a moderate correlation and a large effect size (r = .487, d = 1.315). The mean difference revealed that the online IRS flipped classroom enhanced students\u2019 vocabulary learning scores more than the offline paper-based flipped classroom (MD <\/sub>= 16.782, SDD<\/sub> = 12.928). As a significant difference was observed, the results indicated that the online IRS flipped classroom was more effective than the offline paper-based flipped classroom in enhancing students\u2019 vocabulary learning outcomes.<\/p>\n

    Students\u2019 Perceptions of Paper-Based in Offline Flipped Classroom<\/h4>\n

    The content analysis results showed that the students\u2019 responses highlight two main aspects: benefits and challenges. In the open-ended survey distributed to 46 students, 91% shared their viewpoints, while 9% perhaps did not respond to the open-ended question. From 91% of the views, 48% reflected the benefits of the offline paper-based flipped classroom. A total of 43% students shared the challenges. Students\u2019 views of the benefits were categorized into two aspects: 1) enhanced preparation and comprehension, and 2) increased engagement and enjoyment. On the other hand, students\u2019 views on the challenges were identified into two parts: 1) paper-based format issues, and 2) fatigue and boredom. Table 6 presents the virtues of the offline paper-based flipped classroom in vocabulary learning based on the two categories.<\/p>\n

    Albeit the use of paper in offline flipped classrooms provided many benefits in vocabulary learning, several challenges had also been observed \u2013 these challenges related to paper-based issues, fatigue, and perceived monotony. Fatigue referred to the students\u2019 viewpoints, which showed a state of tiredness, while perceived monotony dealt with the feeling of boredom. Table 5 displays the hurdles of the offline paper-based flipped classroom in vocabulary learning.<\/p>\n

    Students\u2019 Perceptions of Interactive Response System in Online Flipped Classroom<\/h4>\n

    The content analysis results showed that the impact of the IRS in online flipped classrooms dealt with the benefits and challenges. Based on the survey, 94% of respondents shared their viewpoints, while 6% did not provide any input. From 94% of the views, 87% reflected the benefits of the online IRS flipped classroom. A total of 7% students shared the challenges. Students\u2019 views of the benefits were categorized into two aspects: 1) knowledge integration, and 2) enhanced engagement and enjoyment. However, students\u2019 views of the challenges were identified into two parts: 1) internet connection issues, and 2) learning anxiety.<\/p>\n

    The first benefit highlighted that the IRS improved knowledge integration. The IRS assisted the students in having a better understanding of the material and acquiring knowledge effectively. Besides, the IRS supported the students to grasp the notion and retain information, which enhanced their learning outcomes. The second benefit of the IRS in the online flipped classroom underscored that the IRS enhanced engagement and enjoyment. The IRS improved the learning process to be more interactive and enjoyable. This learning experience also encouraged the students\u2019 active participation in classroom activities, making them feel more engaged in the learning process. The following table of students\u2019 responses gave evidence for the virtues of IRS in an online flipped classroom context.<\/p>\n

    Table 9 revealed two challenges students faced when implementing the IRS. The internet connection issues can impede students\u2019 engagement and enjoyment during classroom activities using IRS, as a lagging internet connection can create boredom. Further, some students showed learning anxiety during the class as they thought that they did not have good English competence, so they could not follow the class well. Instead, the learning anxiety led them to feel a little pressure during the learning process.<\/p>\n

    Discussion<\/h3>\n

    The discussion of this study highlights two main points regarding the impact of paper-based instruction in an offline flipped classroom and IRS in an online flipped classroom, based on students\u2019 learning outcomes and perceptions after joining the classes. First, both methods have successfully increased students\u2019 learning outcomes in vocabulary learning. Accordingly, some empirical research has confirmed that visualization through a paper-based method is beneficial for comprehending English vocabulary learning (Alhamami, 2016; Bates & Son, 2020; Gallegos, 2021). However, this contradicts the previous study, which claimed that students\u2019 vocabulary learning outcomes in online IRS outperformed those in the paper-based method (Ahmadian, 2015; Gokbulut, 2020; Rofiah & Waluyo, 2020). The discrepancy might lie in the nature of learners\u2019 attitudes and knowledge backgrounds in experiencing both vocabulary learning methods, as suggested by Wu et al. (2025).<\/p>\n

    Second, the results of students\u2019 perceptions were categorized into two main points \u2013 benefits and challenges, based on each vocabulary learning method. As discernible from the results of the study, the benefits of offline paper-based flipped classrooms consisted of improving academic readiness and engagement. The students reported that the pre-class activities were helpful in preparing for and comprehending the discussed material. Besides, the offline flipped classroom approach fostered increased engagement and enjoyment, making the learning experience more interactive and enjoyable for students. These findings align with those of Khanova et al. (2015) and Wanner and Palmer (2015), who found that the flipped classroom fosters engagement, pre-lecture preparation, and enhances enjoyment. The challenges of the offline paper-based flipped classroom in this study relate to paper-based issues and the associated fatigue and boredom. The students reported difficulties in managing paper-based resources, which led to an increased workload and decreased engagement. Moreover, the monotonous nature of paper-based tasks contributed to feelings of fatigue and boredom. These findings are in the same vein as Pratiwi et al. (2024), who revealed that paper-based methods can lead to student boredom and difficulty in preserving materials, which can easily be damaged or lost.<\/p>\n

    On the other hand, the findings collectively demonstrated the students\u2019 viewpoints on the benefits of IRS utilization in the online flipped classroom, which included enhancing students\u2019 knowledge integration and affective engagement. This was in line with the findings of Anggoro and Pratiwi (2023a) and Wu et al. (2025) in which the students viewed that the IRS contributed to students\u2019 better comprehension and understanding of the materials due to it pointed out its efficacy in recalling, processing, correcting, and reinforcing learned material. This current finding was also congruent with the findings of Balta and Awedh (2017), who reported that IRS enhanced students\u2019 engagement in the class, which in turn supported students\u2019 learning outcomes. This aligns with the work of Wang (2018), who explored the implementation of IRS among college students, underscoring that it fostered course participation, promoted interaction, and enhanced classroom enjoyment. Thus, the integration of the IRS in online flipped classrooms facilitated knowledge comprehension and enhanced students\u2019 engagement, supporting its efficacy as emphasized in prior studies. While the use of the IRS in online flipped classrooms offers numerous benefits, it is not without its challenges.<\/p>\n

    Moreover, the findings revealed two challenges students faced when implementing Interactive Response Systems (IRS). This finding adheres to Anggoro and Pratiwi (2023b) and Aslan and \u015eeker (2017), who found that the internet connection problems impacted students\u2019 accessibility to the IRS, which caused difficulties in answering questions and using the program. Another challenge, learning anxiety, was identified as a barrier to students\u2019 engagement with IRS integration in online flipped classrooms. In this context, learning anxiety deals with students\u2019 anxiety in grasping the learning materials and the anxiety in answering the IRS due to the real-time responses. Albeit most previous studies highlighted that the IRS implementation could reduce students\u2019 learning anxiety (Chang & Lin, 2019; Cheng & Chen, 2022; Xiangming et al., 2020), this finding added a nuanced perspective by demonstrating that the pressure of real-time interaction can enhance anxiety for some students.<\/p>\n

    Capturing the benefits and challenges of offline paper-based flipped classrooms and online IRS flipped classrooms in vocabulary learning contributed to a broader understanding of the potential and limitations of these approaches, as well as finding solutions to the issues. Therefore, teachers and lecturers need to consider the benefits and challenges to create engaging and meaningful learning environments that achieve learning goals and enhance students\u2019 learning outcomes. Furthermore, the study emphasizes that the choice between an offline paper-based flipped classroom and an online IRS flipped classroom should be determined by the learning context, students\u2019 needs, and the institution\u2019s resources. By mapping the benefits, challenges, and potential solutions in vocabulary learning, it fosters the teachers to purposefully adopt, adapt, or hybridize these approaches.<\/p>\n

    Implications and Recommendations<\/h4>\n

    Expanding further on the implications of the study for English vocabulary teaching and learning, course designs in higher education, curriculum development, and policy in English teaching and learning require a deeper exploration of how these insights can be operationalized to enhance educational practices and outcomes.<\/p>\n

    English Vocabulary Classroom Teaching and Learning.<\/strong> The nuanced findings of this study suggest a paradigm shift in classroom teaching and learning towards a more learner-centered approach. Educators are encouraged to employ diagnostic assessments to understand the learning styles of their students better. This understanding can inform the tailored use of IRS to engage and motivate students while employing paper-based methods to reinforce learning and ensure depth of understanding. The integration of technology should be strategic, enhancing learning without detracting from the educational goals. This requires educators to be not only proficient in technological tools but also skilled in pedagogical strategies that effectively blend traditional and modern teaching methods.<\/p>\n

    Course Designs in Higher Education. <\/strong>Regarding course design in higher education, the findings suggest a holistic approach that integrates various teaching methods and assessment strategies to cater to the diverse needs of learners. Course designs should incorporate elements of IRS to stimulate interest and motivation alongside traditional exercises that promote critical thinking and deep learning. Courses should be structured to allow for adaptive learning paths, where students can progress at their own pace and according to their own needs. Assessments should be varied, combining formative assessments that provide ongoing feedback with summative assessments that evaluate comprehensive learning outcomes. This approach ensures that courses are not only engaging and relevant but also rigorous and effective in achieving learning objectives.<\/p>\n

    Curriculum Development. <\/strong>For curriculum development, this study highlights the importance of creating curricula that are both flexible and comprehensive, integrating a wide range of learning activities that cater to different learning preferences. The curriculum should include clear objectives for vocabulary acquisition, incorporating both core and supplementary materials that leverage vocabulary learning by utilizing IRS for engagement and traditional resources for depth. Additionally, it should offer structured pathways for educators\u2019 professional growth, focusing on developing their pedagogical and technological skills to adapt to evolving teaching contexts and emerging educational technologies.<\/p>\n

    Policy in English Teaching and Learning. <\/strong>In terms of policy, the implications extend to the support structures necessary for the effective implementation of innovative teaching and learning strategies. Policies should prioritize the development of a robust digital infrastructure that facilitates access to educational technologies and resources for both students and educators. This includes providing platforms for online learning, digital libraries with access to a wide range of materials, and support for developing custom gamified learning applications. Furthermore, policies should advocate for continuous professional development programs that are accessible and relevant, enabling educators to stay abreast of the latest educational technologies and teaching methodologies.<\/p>\n

    Conclusion<\/h3>\n

    The flipped classroom has sparked interest in EFL classes within the higher education context, replacing the \u2018what to learn\u2019 approach with the \u2018how to learn\u2019 approach in the increasingly technological era, inspiring learning innovations. Previously, the flipped classroom model was implemented using a traditional technique that employed video in an offline setting. Then, the model evolved into an online setting to link distance learning in the current educational era. While vocabulary is the core of language knowledge, it is tedious to acquire a massive number of words at once. The present study reports the students\u2019 vocabulary learning outcomes and explores the impacts of a traditional flipped classroom and an online IRS flipped classroom. Both flipped classroom methods improve vocabulary learning outcomes and enhance students\u2019 engagement and enjoyment. However, the results reveal the differences in effectiveness levels and how the methods support students in vocabulary learning. The online IRS flipped classroom surpasses the traditional flipped classroom in terms of efficacy. While the traditional flipped classroom benefits students in terms of learning preparation, the monotony can lead to fatigue. Moreover, the online IRS flipped classroom supports knowledge integration; however, there are internet connection problems and learning anxiety. Therefore, teachers and policymakers related to education should collaborate to create engaging and meaningful learning environments that achieve the learning goals. Several pedagogical implications concerning English vocabulary teaching and learning, course designs in higher education, curriculum development, and policy in English teaching have been discussed to imply the impacts of a fully online flipped classroom utilizing IRS in vocabulary learning.<\/p>\n

    As much as this study intends to offer, there are several limitations that have to be acknowledged. First, an integrated English subject could lead to time limitations, which creates learners\u2019 anxiety. Focusing an EFL class on vocabulary learning may yield different results, which more precisely reflect the effectiveness of the flipped classroom in vocabulary learning. Second, the notion of technology usage has its limits. The IRS platforms and online classroom setting depend much on the internet connection. The teaching and learning process can be entirely ineffective without supportive infrastructure. Therefore, it is essential to note that the inclusion of IRS in an online flipped vocabulary classroom may enhance students\u2019 learning outcomes and engagement, provided that the school and related education policymakers accommodate the requisite learning assistance. Third, the utilization of multiple-choice vocabulary tests has its limitations in the context of vocabulary use in contextualized communication. Hence, future research may enrich the findings by integrating vocabulary assessment tools, including oral interviews, portfolio assessments, and discourse analysis, to achieve a more comprehensive understanding of vocabulary acquisition.<\/p>\n
