Since its release in November 2022, ChatGPT has become the most debated topic among scholars and is also being used by many users from different fields. Many articles, reviews, blogs, and opinion essays have been published in which the potential role of ChatGPT as a writing assistant is discussed. For this systematic review, 550 articles published six months after ChatGPT’s release (December 2022 to May 2023) were collected based on specific keywords, and the final 30 most relevant articles were finalized through PRISMA flowchart. The analyzed literature identifies different opinions and scenarios associated with using ChatGPT as a writing assistant and how to interact with it. Findings show that artificial intelligence (AI) in education is a part of the ongoing development process, and its latest chatbot, ChatGPT is a part of it. Therefore, the education process, particularly academic writing, has both opportunities and challenges in adopting ChatGPT as a writing assistant. The need is to understand its role as an aid and facilitator for both the learners and instructors, as chatbots are relatively beneficial devices to facilitate, create ease and support the academic process. However, academia should revisit and update students’ and teachers’ training, policies, and assessment ways in writing courses for academic integrity and originality, like plagiarism issues, AI-generated assignments, online/home-based exams, and auto-correction challenges.","PeriodicalId":37088,"journal":{"name":"Contemporary Educational Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41984134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the application of the instrument Digital Literary Education and the Construction of Gender Identities (DLECGI), the study is developed in non-experimental designs of a cross-sectional nature, and at the relational, explanatory and predictive levels of research, insofar as it seeks to reveal the socio-demographic, formative and didactic causes of the phenomenon or event of interest, and its degree of occurrence. The results obtained indicate the existence of a profile of teachers who promote the recommendation of this type of digital reading based on their belonging to non-binary gender groups with previous training in co-education and equality, and with explicit didactic stances on controversial issues. Likewise, the relationship between socio-demographic variables and the didactic positioning of teachers on the recommendation of digital readings on affective-sexual diversity shows that initial and/or ongoing specific training in co-education and equality is a key predictor of this relationship. These findings attest to the fact that the visibility and recognition of identity plurality in literary education necessarily involves the proposal of counter-hegemonic models regarding gender and affective-sexual identity. In this regard, teacher training must continue to progress towards the adoption of inclusive didactic approaches within the framework of educational principles for democratic citizenship, regardless of the gender or personal and social identity that defines these teachers.","PeriodicalId":37088,"journal":{"name":"Contemporary Educational Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42089760","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A meta-analysis was conducted to combine the findings of independent experimental studies. The studies included in this review were sourced from reputable databases such as Web of Science, Scopus, IEEE, ACM, and ScienceDirect. The results indicate that students who learn in a virtual environment achieve higher learning scores compared to those in traditional classrooms (standard mean difference [SMD]=0.64, 95% CI [0.36, 0.92], p<0.001). Additionally, the findings suggest that learning in a tethered VR environment is equally effective as learning through mobile VR. Furthermore, there were no significant differences in scores when different media materials were used for the control group. This review emphasizes the advantages of employing mobile VR for learning in contrast to using tethered VR.","PeriodicalId":37088,"journal":{"name":"Contemporary Educational Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47408061","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research aims to identify the differences between undergraduate students’ perceptions and preferences on emergency remote and online education. Researchers identified a set of online education courses–that pre-existed COVID-19 times–and courses that were transformed into remote education courses–designed as a response of the COVID-19 emergency. Participants of this study are a group of students who, during the same academic semester, participated in both online and (emergency) remote courses. Researchers used a survey to understand students’ perceptions and preferences assessing their experiences in different dimensions (e.g., interaction and evaluation). Researchers used the add-on preferential groups model to identify which of the two modalities was preferred by the students for each dimension. The quantitative analysis was complemented using content analysis of responses to open-ended questions, seeking to gain a better understanding of students’ perceptions and preferences between online and emergency remote education. The results show that students have a positive view of the online and remote modalities; however, each of these modalities offers students advantages for specific dimensions. For example, the remote modality was preferred for having greater interaction among peers and with the instructor. On the other hand, online education provided more flexibility. Students suggested improving assessments’ approaches and instructors’ technological skills for both modalities.","PeriodicalId":37088,"journal":{"name":"Contemporary Educational Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43347812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hypothesis testing revealed that high expectations and changes in viewpoints positively impacted self-concept, ability, and motivation, contributing to improved learning outcomes. The integration of technology in teaching facilitated these transformations, demonstrating how digital tools like virtual reality, interactive platforms, and online tutorials can enhance learning experiences. However, the effect on learning gain varied when viewpoints changed, indicating a need for further research into the differential impact of technology on learning outcomes.

This quasi-experimental study examined the impact of flipped teaching on motivation and self-directed learning attributes among 106 entrepreneurship students at universities in Taiwan. Students completed pre- and post-intervention surveys measuring intrinsic motivation, extrinsic motivation, and facets of self-directed learning. Bayesian paired samples t-tests revealed that flipped instruction significantly increased both intrinsic and extrinsic motivation. Self-directed learning attributes including internal processes, behavioral approaches, and environmental preferences also improved following the flipped teaching intervention. Additionally, machine learning models were developed to predict students’ final exam scores based on pre-intervention motivation, self-directed learning, and learning expectations. A linear regression model accounted for 59.1% of variance in exam scores, with pre-learning expectations emerging as the strongest positive predictor. However, pre-intervention intrinsic motivation intriguingly showed a negative relationship with predicted exam performance. Overall, this study provides preliminary evidence that flipped instruction can increase student motivation and self-directed learning capabilities. The predictive modeling also suggests complex interactions between attributes in influencing academic achievement. Further research with larger, more diverse samples is recommended to validate the motivational and self-regulatory benefits of flipped teaching for higher education students.","PeriodicalId":37088,"journal":{"name":"Contemporary Educational Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43910191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Seven English education majors enrolled in the course “teaching internship 2” in their fourth year at a Thai university participated in the study. Due to COVID-19, the participants were trained to teach online, but during their teaching practicum, they were required to teach in a traditional on-site setting. Because of this novel arrangement, it was essential to investigate how these PSTs incorporate technology into the classroom. For the purpose of analyzing the process of educational technology integration, this study employed SAMR model. Observations and semi-structured interviews were used as data collection methods. Throughout the semester, observations were conducted twice. SAMR observation form was used to investigate how PSTs used technology in their teaching. Participants were asked to participate in an interview after each observation. The interviews included open-ended questions based on the conceptual framework of SAMR. Observation results show that technological tools were used to engage students, check comprehension, create teaching content, and evaluate students’ understanding. For the study, the participants were divided into three groups based on the extent of technological tools used. One participant was deemed to be in the substitution stage, five participants in the augmentation stage, and only one participant in the modification stage. The results of the interviews indicated that teacher motivation and the availability of ICT equipment, as well as familiarity with technological tools, played a significant role in PSTs’ integration of technology into the classroom. The study’s conclusions are helpful in developing PSTs’ technology integration in EFL classrooms. SAMR model should be introduced to PSTs to let them critically reflect on and develop their own technology integration.","PeriodicalId":37088,"journal":{"name":"Contemporary Educational Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46611406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These participants were systematically divided into an experimental group (EG) and a control group. Both groups engaged in the same organic chemistry lesson and subsequent lab session, the only difference being that EG received additional training via a virtual laboratory prior to the hands-on lab session. A survey, conducted both before and after the experiment, was utilized to measure participants’ attitudes towards the use of virtual laboratories. The quantitative data analysis revealed a significant positive shift in EG’s attitudes post-intervention, suggesting that virtual laboratory experiences enhance their learning and engagement. Specifically, participants exhibited improved understanding of the educational methodologies and heightened engagement during the physical lab work. However, no significant differences were observed between the two groups concerning the technical aspects of the experiments, implying that the virtual labs’ impact on perspectives about the technical components of a chemistry lab was consistent across both groups. These findings support the view of virtual laboratories as a viable supporting tool for science education, promoting technology integration into teaching practices to meet the demands of 21<sup>st</sup> century learning outcomes.

The use of technology greatly bolsters the integration of these skills. Robotics, one of the many emerging arrays of technologies, presents learners with challenges and opportunities for developing innovative ideas, critical thinking, and higher-order thinking skills. As a result, the Ministry of Education in Dubai realized these potentials and took an essential step in the form of the distribution of Lego Mindstorms Education kits to schools with the goal of encouraging teachers to use these kits in their classrooms. This research study aimed to investigate teachers’ perceptions of a training on Lego Mindstorms in terms of content, methodology, activities, and recommendations. In addition, the study investigated how teachers perceived Lego Mindstorms based on TAM model. A total of 59 high school (cycle 2) teachers participated in the current study. The data from the teachers were collected using both quantitative and qualitative approaches. Data analysis consists of descriptive statistics and thematic analysis. Teachers showed positive perceptions of robotics integration, emphasizing its potential to enhance teaching and learning. Their willingness to learn and adapt, combined with their recommendations for enhanced training methods, highlights the importance of continuous professional development for effective robotics integration. Teachers expressed the need for more practical training, hands-on activities, and a balance between theoretical and practical aspects. A positive correlation between perceived learning usefulness, perceived teaching usefulness, perceived ease of use, attitudes, and teachers’ intention to use Lego Mindstorms in their future teaching was found.","PeriodicalId":37088,"journal":{"name":"Contemporary Educational Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46568039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
