This control condition allowed us to investigate the natural progression of language learning without the influence of additional educational interventions. By comparing the language learning outcomes of the control group with those of the experimental groups, we were able to assess the effectiveness of the AI-driven language learning interventions implemented in Group 2 and Group 3. The control group’s participation provided valuable insights into the baseline language learning trajectory and served as a reference point for evaluating the impact of the advanced AI tools used in the experimental groups. This comparative analysis enabled us to gain a comprehensive understanding of the benefits and effectiveness of the AI-driven language learning experiences provided to participants in Group 2 and Group 3.

2.2. Instruments

2.2.1. Self-Regulated Learning Scale

The self-regulated learning scale used in this study was adapted from Şahin Kızıl and Savran [27] and consisted of a nine-item scale. This scale was designed to measure the extent to which the participants engaged in self-regulated learning skills, focusing on aspects such as goal setting, time management, self-monitoring, and adaptive learning strategies. The questionnaire was administered to all participants at two key points in the study: prior to the commencement of the intervention sessions (pretest) and upon completion of the intervention sessions (posttest). The pretest data collection allowed for the baseline assessment of the participants’ self-regulated learning skills, while the posttest data collection aimed to capture any changes or improvements in these skills following their exposure to the different experimental conditions. The reliability coefficient estimate of the administered scale in this study was found to be .87. This data collection process provided valuable insights into the impact of the interventions on the participants’ self-regulated learning skills and contributed to the overall assessment of the study’s objectives (see Appendix A).

2.2.2. Language Proficiency (Pretest-Posttest)

The language proficiency of the participants was assessed using a comprehensive language proficiency test at two key points in the study: prior to the commencement of the intervention sessions (pretest) and upon completion of the intervention sessions (posttest). The language proficiency test was designed to measure the participants’ proficiency in various language skills, including speaking, listening, reading, and writing. The pretest assessment provided a baseline measure of the participants’ language proficiency levels before exposure to the experimental conditions, while the posttest assessment aimed to capture any changes or improvements in their language proficiency following their participation in the intervention sessions. The language proficiency test utilized in this study consisted of a total of 100 items, with 25 items dedicated to each language skill section (speaking, listening, reading, and writing).

Each section of the test was scored separately, with a maximum score of 25 points for each language skill. The total score for the language proficiency test was calculated by summing the scores from all four sections, resulting in a maximum possible score of 100 points. The test items covered a range of linguistic competencies, including vocabulary knowledge, grammatical accuracy, comprehension of spoken and written language, and communicative fluency. The reliability and validity of the language proficiency test were established through rigorous piloting and validation processes. The reliability and validity of the language proficiency test were established through rigorous piloting and validation processes, which yielded reliabilities ranging from .72 to .78.

2.2.3. Participants’ Perceptions of the Administered Treatments

The study examined participants’ perceptions of the administered treatments through a structured feedback questionnaire. This questionnaire was designed to capture their experiences, satisfaction, and perceived effectiveness of the intervention sessions. It was administered to all participants following the intervention sessions (posttest) and aimed to gather both qualitative and quantitative data on their perceptions of the different treatment conditions. The questionnaire items covered topics such as the effectiveness of chatbot-based language learning support, adaptive learning algorithms, and virtual reality language immersion in facilitating language learning and self-regulated learning.

Participants were also asked to rate their satisfaction with the intervention content and delivery, perceived relevance of the materials, and overall experience with the intervention sessions on a 7-point Likert scale. Additionally, participants were encouraged to provide qualitative comments and suggestions for improvement, allowing for a comprehensive understanding of their experiences. The feedback questionnaire was designed to capture both objective and subjective aspects of the participants’ perceptions, providing valuable insights into the effectiveness and acceptability of the administered treatments. The data collected from the feedback questionnaire provided rich qualitative and quantitative information on the participants’ experiences and perceptions of the intervention sessions (see Appendix B). The reliability test revealed that the subscales had reasonable reliabilities ranging from .69 to .78.

2.2.4. Interviews

To facilitate a free flow of ideas from the participants, an open-ended interview was developed to elicit participants’ perceptions of the efficacy of the administered educational intervention (see Appendix C). Ten open-ended questions were used to interview experimental groups based on their experiences with the intervention sessions, language learning support, and immersion technologies. The interview questions were carefully crafted to explore topics such as the perceived impact of the interventions on language skill development, the effectiveness of specific learning support tools, and the overall satisfaction with the intervention content and delivery. We invited two raters to code interview data in order to obtain efficacy ratings of the educational intervention by triangulating questionnaire and interview data. The raters’ reliability was very high, with kappa coefficients ranging from 0.84 to 1.0. This approach allowed for a comprehensive assessment of the participants’ perceptions and experiences, integrating both qualitative and quantitative data sources.

The qualitative data obtained from the interviews provided rich insights into the participants’ experiences with the interventions, offering a deeper understanding of their perspectives and allowing for a more nuanced analysis of their feedback. The open-ended nature of the interview questions allowed participants to express their thoughts and reflections in their own words, providing valuable qualitative data that complemented the quantitative data collected through surveys and questionnaires. The quantitative summary of the data elicited by the interview was generated by coding the answers into four response categories (1 = no, 2 = partially no, 3 = partially yes, 4 = yes), allowing for a structured analysis of the qualitative responses. This coding process facilitated the extraction of patterns from the interview data, contributing to a comprehensive understanding of the participants’ perceptions and experiences.

2.3. Data Analysis

To address the first research question, ANOVA [28] was employed to conduct statistical analyses comparing the language learning proficiency, self-regulated learning skills, and overall language learning experience of EFL learners engaged with online instructors using chatbot-based language learning support and adaptive learning algorithms with those in the comparison group. This multivariate approach provided a comprehensive examination of the impact of these instructional methods. Additionally, subgroup analyses using ANOVA were performed to discern any significant differences by the type of virtual reality language immersion implementation, allowing for a nuanced understanding of the specific effects of different immersion approaches.

In addressing the second research question, a rigorous qualitative inquiry was conducted. Critical thematic analysis [29], underpinned by a constructivist paradigm, was utilized to uncover and interpret the multifaceted perspectives of EFL learners. This approach involved identifying recurring patterns within the qualitative data derived from interviews and open-ended survey responses. By delving into these qualitative insights, a deeper understanding of the learners’ perceptions regarding the effectiveness of virtual reality language immersion, chatbot-based support, adaptive learning algorithms, and their potential synergies and interactions in augmenting the language learning experience for EFL learners was achieved. The triangulation of quantitative and qualitative data provided further insights into the effectiveness of different instructional methods and their impact on EFL learners’ language learning experiences.
