Introduction
English language training has become increasingly important in the globalized world, where it serves as the primary language for communication in various fields [1].However, conventional teaching methods may not be sufficient to equip students with the critical thinking and independent learning skills necessary to effectively apply the English language in real-life situations and address sustainability challenges [2].As such, it is essential to investigate the role of immersive digital technology in promoting critical thinking and independent learning in English language education for achieving sustainability and how collaboration can enhance the effectiveness of this approach.
Constructivism serves as one theoretical foundation for using digital immersive technologies in education, as it posits that students actively construct their understanding of the world through experiences and interactions with their environment [3].This process can aid digital immersive technology by providing students with access to interactive, realistic worlds to explore and experiment with, allowing them to gain a deeper understanding of concepts and ideas.
Digital immersive technology can encourage English language students to actively engage with the language, explore its many facets, and try various techniques to foster critical thinking, self-directed learning, and teamwork [4][5][6][7].It may result in students having more confidence in their skills and better language comprehension.Digital immersive technology can also assist students in identifying areas for improvement by providing them with immediate feedback on their performance.It can help students develop their critical thinking and self-directed learning abilities.Students can build cooperation and communication skills through peer collaboration, allowing them to succeed in their studies and future employment [5].
English language instruction is essential for developing a learner's linguistic abilities, cultural sensitivity, and sense of civic responsibility.Conventional teaching techniques, including lectures and rote memorization, might not be enough to allow students to utilize English successfully in everyday circumstances and deal with sustainability-related issues [6].Thus, there is a rising interest in examining how teamwork may support this process and the function of digital immersion technology in fostering critical thinking and self-directed learning for achieving sustainability in English language teaching [7].In the context of this study, the concept of teamwork is intricately woven into the broader framework of digital immersive technology's influence on the education of English language students.Teamwork is examined as a collaborative element facilitated by digital immersive experiences, wherein students engage in joint learning activities, projects, or simulations.The relationship between teamwork and the other variables-critical thinking, self-directed learning, and sustainability-is crucial for understanding the holistic impact of digital immersive technology in education.
Teamwork is anticipated to play a pivotal role in fostering critical thinking skills among students.Through collaborative efforts, students are likely to engage in diverse perspectives, problem-solving scenarios, and analytical discussions, thereby contributing to the development of critical thinking abilities.Additionally, the collaborative nature of teamwork is expected to enhance self-directed learning practices by encouraging students to take ownership of their learning within a group dynamic.The exchange of ideas, shared responsibilities, and peer-topeer learning within a team may empower students to autonomously direct their educational journeys [2.3,5].
Moreover, the collaborative environment fostered by teamwork is envisaged to have positive implications for sustainability in education.By working together towards common goals, students may develop a sense of shared responsibility for their learning outcomes, creating a sustainable learning community.This communal approach is likely to contribute to the longevity and effectiveness of educational practices, reinforcing the notion of sustainability within the broader educational context [6].
In essence, the relationship between teamwork and critical thinking, self-directed learning, and sustainability represents a symbiotic dynamic, wherein the collaborative nature of teamwork is anticipated to positively influence each of these variables, ultimately shaping a more comprehensive and effective educational experience for English language students within the realm of digital immersive technology.
This article aims to examine the contribution of digital immersion technology to the promotion of critical thinking and self-directed learning, as well as how teamwork might increase the efficacy of this method.The problem statement in the report goes on to describe the study's goals and research questions.An overview of the research strategy and methodologies provide as the publication ends.
Virtual and augmented reality are two forms of immersive digital technology that increasingly use in various educational contexts, including English language instruction.Digital immersive technology offers students an immersive and interactive learning environment that can boost motivation, engagement, and memory recall [8].Digital immersive technology can use in English language instruction to create virtual environments that mimic real-life circumstances, where students can practice their language skills, gain confidence, and increase their cultural understanding [9].Digital immersive technology can provide learners with immediate feedback, personalized learning paths, and collaborative learning opportunities.Critical thinking is an essential skill that enables learners to analyze, evaluate, synthesize information, and make informed decisions and judgments [10].Necessary thinking abilities are crucial for learning English since it requires students to comprehend and evaluate complicated texts and successfully communicate their views in a multilingual and multicultural setting [11].Digital immersive technology can encourage critical thinking by allowing students to practice problem-solving, making decisions, and reflecting [12].For instance, students can investigate other viewpoints and cultural contexts, assess the reliability of sources, and create their arguments and conclusions using immersive digital technology [13].Another crucial ability is self-directed learning, which empowers students to take charge of their education, establish their objectives, and track their advancement.Self-directed learning is especially vital in English language education, where students must develop their language skills across various subjects [14].For example, learners can use immersive digital technology to access authentic materials, practice their language skills in different contexts and situations, and receive personalized feedback and support.Digital immersion technology promotes critical thinking and self-directed learning in English language education for sustainability, and teamwork is another crucial component.Collaboration, communication, and social learning can all facilitate by teamwork [15].Also, teamwork may give students a variety of perspectives, abilities, and experiences, as well as the ability to solve challenging challenges and accomplish shared objectives.Teamwork can utilizes in teaching the English language to foster collaborative learning settings for students [16].
The current study aims to explore the role of immersive digital technology in instructing English language learners and its potential to foster critical thinking and selfdirected learning.The relationship between the usage of immersive digital technology and critical thinking and self-directed learning will examine, as well as the moderating impact of teamwork.The importance of this study rests in the fact that it will add to the body of knowledge already available on the use of technology in language instruction and give insight into how digital immersive technology may use to support sustainable education.To achieve sustainability in education, the results of this study will be helpful to language educators and policymakers in developing methods for integrating digital immersion technology in language teaching and learning.
The English language is widely used in international commerce, academia, and the media and has emerged as a lingua franca on a global scale.As a result, learning is essential for students who want to flourish in the worldwide economy.Additionally, one of the most often used methods of language instruction worldwide is teaching English.The demand for creative language teaching strategies that can encourage critical thinking, self-directed learning, and teamwork among English language learners, this study focuses on English language teaching.Even though the study's primary focus is on teaching English, its findings might also apply to other languages [17].Many of the guiding principles of digital immersive technology, such as stimulating inquiry, giving prompt feedback, and encouraging collaboration, probably apply to various languages [17].In order to obtain the best outcomes, digital immersive technology may need to tailor to each language's features and challenges specifically.Therefore, this study's results may be insightful into language teaching methods, but they might not be directly applicable to other languages without additional study and adaption.
Although there is a growing corpus of studies on technology's usage in language learning, there is a shortage of studies on how digital immersive technology might foster self-directed learning and critical thinking to achieve sustainability in education.There has been little research on immersive digital technology like virtual and augmented reality, with most studies concentrating on traditional technology like computers and multimedia in language teaching and learning.Also, as it does not cover in the existing research, it is necessary to investigate the potential moderating impact of teamwork on the relationship between the use of immersive digital technology and critical thinking and self-directed learning.By examining the potential of immersive digital technology to advance sustainable education in language teaching and learning, this study seeks to fill these gaps in the literature.
The study will be divided into several components to accomplish its goals.An overview of the body of research on digital immersion technology, critical thinking, selfdirected learning, teamwork, and English language instruction will cover in the first portion.This section will present the study's theoretical foundation and point out any gaps in the knowledge that require filling.The second section will involve creating and distributing a survey questionnaire to English language instructors and students to learn more about how they use digital immersive technology.The third portion will deal with selecting and using specific digital immersion technologies in teaching the English language, emphasizing those successful in the prior study.Additionally, information on students' linguistic abilities, motivation, and involvement in the learning process will gather in this part, along with information on their critical thinking, self-directed learning, and teamwork abilities.The analysis and interpretation of the data will cover in the last portion, which will combine quantitative and qualitative techniques.The study's findings will apply to create best practices for integrating digital immersion technologies into English language instruction and pinpoint areas requiring more study.

Based on Fig. 1, and in line with above mentioned literature, the following hypothesis is stated: H10: Team working will moderate the association of the use of digital immersive technology and self-directed learning.

Population, sampling and data collection
This research utilized the foundations of quantitative research design for hypothesis testing [48].The target population of the study consisted of the students of various universities located in Beijing.The reason to select the target population from the universities located in Beijing is that, the city is ranked no. 1 when it comes to higher education institutes [49].This can better represent the other regions as well and the results obtained from this city will be generalizable too.For selecting the respondents form the target population, we visited the universities physically to contact with the respondents' and to explain the purpose of the study.Students were asked various preliminary questions about the use of technology in their education and only those were selected who tend to use or have used digital technology to leverage their studies.We thus applied conveniently and purposefully selected the respondents [50]; non-probability sampling techniques, which were helpful to select the respondents according to the objectives of the study.Moreover, we first approached the student's help desk, cafeterias to easily access the respondents.The students who were willing to participate were explained the purpose and scope of the study.After this, a standardized survey questionnaire was shared with the respondents to get their responses.The first section of the questionnaire asked some basic questions i.e., degree program, field of study, level of degree, gender, access to internet, etc., The second section comprised of questions related to the key variables of the study.A total of 304 respondents filled the questionnaire out of the distributed questionnaires which were used for further analysis.

Data collection
This research was composed of 5 different variables: an independent variable "use of digital immersive technology", a dependent variable "sustainable education", two mediating variables "critical thinking" and "self-directed learning" and a moderating variable (team working).The research instrument was based upon these 5 variables and contained 27 questions specifically related to these 5 variables.The data was collected about these questions on a seven-point Likert scale ranging from 1 to 7 (1 = Strongly Disagree to 7 = Strongly Agree).All the questions were adapted from previous researches and were already validated.To meet the objectives of current study, we modified 5 items of the variable "use of digital immersive technology", 3 items of sustainable education [51], 5 items of critical thinking [52], 5 items of selfdirected learning [53] and 9 items team working [54] (See Appendix).

Data analysis
In order to meet the objectives of the study, we conducted data analysis by utilizing the valid responses from 304 respondents.Notably, the study composed of 5 variables i.e., use of digital immersive technology, critical thinking, self-directed learning, sustainable education, and team working.It was examined whether direct and indirect association exists between the variables of the study and whether these relationships were subject to the variation of the moderating variable "team working".For this purpose, we applied SEM approach by employing Mplus [55].But before moving to the hypothesis testing, various preliminary assessments were made including "multivariate normality testing", "model fitness testing through confirmatory factor analysis" and the "test of common method bias".Mplus 7 requires the shorter names of the variables to be assigned for their effective handling.Therefore, for conveniently operating the software for data analysis, it is recommended that the names of the variables should not exceed 8 characters [56] and 90 characters per line [57].Keeping this in mind, we shortened the names of study variables i.e., use of digital immersive technology, sustainable education, critical thinking, self-directed learning and team working to "DGIT", "SED", "CRT", "SDL" and "Team", respectively.

Model fitness
Prior to the assessment of hypothesis, mode-fit indices were examined to find out whether the data optimally fits with the conceptual model.It was essential to conduct the confirmatory factor analysis as the aim of the study was to test the theory.We therefore, the examined the famous model fit indices generated through Mplus i.e., chi-square, SRMR, RMSEA, CFI, and TLI, and their values were compared with the cut-off criteria.All the models fit-indices reflected that the model is perfectly fit for hypothesis testing.The details of the model fit indices are provided in Table 1.

Validity, reliability and descriptive statistics
Additionally, the validity and reliability of the model was further confirmed by calculating the convergent and discriminant validity [58][59][60].It was important to assess the constructs' discriminant validity to confirm that the concepts which were not theoretically related were unrelated.For this purpose, we first computed the SQRT (squared root) of AVE (average variance extracted) and compared these values with correlation of the of the constructs.The analysis confirmed that the SQRT of AVE was significantly the greater than their corresponding correlations, thus confirming that the variables which were theoretically different were actually different [61], depicting the existence of discriminant validity.Furthermore, for the assessment of convergent validity, we examined the standardized factor loadings & AVE of the constructs [62].It was observed that the factor loadings (STDYX) and AVE met the recommended criteria [59][60][61][62], because AVE was significantly higher than 0.5 and STDYX of all the factors (see Fig. 2) were greater than 0.4 [63,64].
In addition to this, the internal consistency of the scale was examined by computing composite reliability (CR).The analysis confirmed (see Table 2) that the CR values of all the observed variables were significantly higher than 0.7.The highest value of CR (0.94) was associated to the moderating variable "TEAM", whereas its lowest value (0.833) was linked to one of the mediating variable "CRT". of the data by highlighting the MEAN, STD values.Looking at the MEAN and STD values, it can be found out that the normality of the data was not violated.Finally, it was essential to compute multicollinearity to confirm that the constructs are not highly correlated.The analysis revealed that although the variables were significantly correlated but still these values were far lesser than 0.9 and thus do not indicate the issue of multicollinearity [65].

Testing the CMV/ biasness of responses
The data related to the study variables was collected at a single point of time using the same questionnaire, therefore, it was deemed necessary to test whether the individuals' responses were influenced by their predispositions or not.For this purpose, a test of CMV (common method variance) was conducted.A famous technique of Harman's single-factor method was applied to determine the biasness of the respondents if any.The results of the test revealed that one factor only explained 35.09% of the variance.These results that the relationship between the variables did not occur due to the biased beliefs of the respondents because the one factor accounted for significantly lesser than 50% of the variance.It was confirmed that there was no issue of common method biasness [66].Table 2 presents descriptive statistics, correlation and discriminant validity indices.

Hypothesis testing for direct, indirect and moderated relationships
Moving ahead with the hypothesis testing, the structural equation modelling approach was applied to run the direct, indirect and the moderated relationships.As the model involved the testing of both direct and indirect associations, therefore, the significance of all such hypothesis was first examined by applying SEM.The first 5 hypothesis were linked to the assessment of direct associations between DGIT, CRT, SDL and SED.The results revealed that DGIT significantly predicted SED, β (STDYX) = 0.209, SE = 0.061, T-value = 3.432, P-value = 0.00, CRT β (STDYX) = 0.348, SE = 0.056, T-value = 6.185,P-value = 0.00, and SDL, β (STDYX) = 0.363, SE = 0.057, T-value = 6.378,P-value = 0.00.Therefore, H1, H2 and H3 were significant and supported.H4 was related to the assessment of direct association between CRT and SED, whereas H5 was linked to the assessment of SDL-SED relationship.As per the expectations, both CRT and SDL positively and significantly predicted SED, β (STDYX) = 0.155, SE = 0.065, T-value = 2.393, P-value = 0.017, β (STDYX) = 0.381, SE = 0.062, T-value = 6.112,P-value = 0.00 respectively.These results (see Table 3; Fig. 3) confirmed all the direct paths in the model were positive and significant.Combined with the direct effects, we also examined the mediated paths present in the structural model.For this purpose, the mediating role of CRT and SDL was investigated between the independent variable "DGIT" and dependent variable "SED" respectively.The following Table 4 contains detailed information about the indirect effects.
The significance of the indirect paths was determined by observing the p-value, t-value, and 95% ULCI and LLCI of the specific indirect effects.It is recommended that the sample should be artificially increased to 1000 bootstraps at least, for obtaining the reliable results of mediations [67] and trust worthy confidence intervals [68,69].However, we opted for an even larger no. of bootstraps i.e., 5000-bootsraps.Continuing with the analysis, H6 assumed that CRT will significantly mediate the association of DGIT and SED.Contrary to the expectations, it was proved that this specific indirect effect was insignificant* because of its STDYX β-value = 0.054 (SIE), SE = 0.029, T-value = 1.874 and P-value = 0.061 (see Table 4; Fig. 3).Nevertheless, a test for 95% of CI proved to be significant because its upper and lower values did not pass through zero 0.007-0.101(692).Therefore, being stringent on the measure, it was interpreted that H6 was not supported.Likewise, H7 postulated that SDL will be useful for connecting the DGIT and SED.As per the prediction, this indirect effect was positive and significant, STDYX (β) = 0.138, with SE = 0.034, T-value = 4.083 and P-value was 0.000.This significance was also proved through the examination of 95% CI as the lower limit of 95% and upper limit of 95% CI did not pass through zero i.e., 0.082-0.194.Therefore, H7 was supported (see Table 4; Fig. 3).
Finally, we examined the moderating role of teamwork between DGIT-SED, DGIT-CRT and DGIT-SDL through H8, H9, H10 respectively.It was established that the effect of interaction term (DGIT x TEAM) was significant and positive β = 0.214, SE = 0.090, T-Value = 2.369 and its p-value was 0.018.Additionally, the 95% CI also did not go through zero (see Table 5; Fig. 3).Thus, H8 was supported.As far as the moderating role of TEAM on DGIT-CRT path is concerned, the moderation proved to be negative and highly insignificant* in this case.It can be observed that β= -0.40, SE = 0.096, T-Value = − 0.413 and its p-value was 0.680.In addition to this, the 95% of CI also proved that the moderation was insignificant* (see Table 5; Fig. 3).At the end, the moderation of TEAM on the DGIT-SDL path was investigated.Looking at results, it was established that the moderating variable "TEAM" significantly strengthened the relationship of DGIT-SDL, i.e., STDYX β-coefficient = 0.201 SE = 0.091, T-value = 2.231, p-value = 0.027.Moreover, the analysis of 95% CI revealed that ULCI and LLCI did not include zero (see Table 5; Fig. 3) indicating that the moderating role was positive and significant.Thus, as per the assumptions of the researcher, H10 was supported.

Policy implication
Regardless of socioeconomic background, policies should guarantee that all pupils have access to digital immersive technology.It can be by financing schools specifically intended for them or by forming alliances with IT firms to provide people with care.Also, policies addressing how to incorporate digital immersive technology into language programs for teachers successfully should be devised.Helping instructors stay current on the newest technologies and best practices can involve ongoing  support, resources, and professional development opportunities.Governments should support the creation of a digital immersive language curriculum and offer recommendations on how to apply these technologies best to foster critical thinking and self-directed learning.It may entail creating criteria for measuring language proficiency online and standards for planning and executing immersive language-learning activities.Digital immersive technology should be encouraged by policies to foster student participation and teamwork.It can involve creating language-learning activities that encourage students to cooperate to attain a common objective and allow them to reflect on their learning and share their experiences.
Digital immersion technology has the potential to encourage teamwork, self-directed learning, and critical thinking, all of which are crucial for achieving sustainability in education.Policymakers may assist in ensuring that kids have access to technology by creating that encourage teacher training, curriculum creation, and cooperation.

Practical implications
Students can benefit from tailored learning experiences made possible by digital immersion technology.Students can practice their language abilities in context by using virtual environments that teachers can construct that mimic real-life situations.Forcing children to use their linguistic skills to solve problems can aid in developing their critical thinking abilities.Moreover, collaboration and teamwork among students can be facilitated through digital immersive technology.Students can collaborate on activities, talk about linguistic ideas, and give one another feedback by using digital platforms.Collaborative learning like this promotes independent learning and aids in the growth of crucial interpersonal and collaboration abilities in pupils.Thanks to digital immersion technologies, students may gain access to real-world experiences that they might not otherwise have.For instance, students can tour historical landmarks, engage with English-speaking natives in virtual environments, or visit virtual museums.These opportunities can foster critical thinking abilities in pupils and help them gain a deeper understanding of the language and culture.Students may benefit from digital immersive technology's freedom in their learning.Online tools and resources for language study are always available to students and from any location.It can assist students in taking ownership of their education and fostering their capacity for independent study.Assessment of student learning can also use digital immersion technologies.Teachers can use digital platforms to monitor student progress, give comments, and pinpoint areas where students need more assistance.
It can encourage self-directed learning by providing students with the resources they need.

Theoretical implications
The constructivist learning philosophy emphasizes active and interactive learning via inquiry and discovery and aligns with digital immersive technology.Thanks to digital immersive technology, students can learn a language in a virtual setting and connect language ideas to practical situations.Having the freedom to create their conceptualizations of the language encourages critical thinking and self-directed learning in the students.Digital immersive technology is fundamentally dependent on collaborative learning.It facilitates student collaboration and communication while supporting the social creation of knowledge.As a result, students gain crucial abilities required for achieving sustainability in education, including problem-solving, critical thinking, and effective communication.
By giving students the resources, they need to keep track of their progress and assume responsibility for their learning, digital immersion technology can also support self-directed learning.It is consistent with the selfdirected learning idea, which strongly emphasizes the necessity of giving students ownership over their own learning.The move to technology-enhanced understanding, which acknowledges the importance of technology in augmenting and transforming the learning experience, is represented by digital immersive technology.In addition to encouraging sustainability in education, this strategy acknowledges the potential of digital immersion technology to foster critical thinking, self-directed learning, and teamwork.The development of 21st-century abilities, such as teamwork, critical thinking, and digital literacy, which are crucial for success in the modern world, is encouraged by digital immersion technology.The 21st-century learning theory, which emphasizes the need to prepare students for the demands of the digital age, is in line with this.
