This approach evaluates online learning more reasonably, operably and feasibly. To overcome limitation of using more than one method in the evaluation of learning performance, the learning performance of online learners was first evaluated using the principal component analysis method, entropy method, comprehensive indicator method, and TOPSIS method. Based on these four evaluation results, a combination evaluation model of online learners’ learning performance was constructed. The Fuzzy Borda method was used to evaluate nine administrative classes of accounting majors in three colleges and universities in Hainan. The results show that simply using a single evaluation method to evaluate the learning performance of online learners has defects, and the evaluation results are too biased. By using the Fuzzy Borda method, multiple evaluation methods can be combined, allowing a single evaluation method to realize complementary advantages and obtain more comprehensive and credible evaluation results. Using the Fuzzy Borda method to systematically evaluate the learning performance of online learners improves the scientificity of evaluation results and provides a new idea and method for the evaluation of online learning performance. The results of this study have significant reference value for using scientific evaluation methods and objective data to evaluate online learning performance, rank online learners scientifically, and summarize teaching experience to improve online learning performance.","PeriodicalId":47933,"journal":{"name":"International Journal of Emerging Technologies in Learning","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49152056","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}

Therefore, conducting a scientific evaluation of quality of project-based teaching is crucial. In this study, the focus was on the process of project-based teaching, involving 120 computer science and technology students from four universities in Hainan Province. The researchers utilized the slacks-based measure and data envelopment analysis (SBM-DEA) model to measure learning efficiency of these students. Additionally, the study analyzed the insufficient investment in project-based teaching in the four universities and identified the process factors affecting quality of project-based teaching. The results show that out of the 120 students, only 24 students achieved a learning efficiency of 1, accounting for only 20% of the total. This indicates that although project-based teaching is implemented in the surveyed schools, the comprehensive improvement of students’ learning efficiency has not been achieved. The two main factors contributing to the low quality of were identified as project-based teaching aids (X-2) and project-based teaching experience (X-3). The findings of this study hold important reference value for optimizing the project-based teaching process, identifying key factors of project-based teaching quality, and promoting the adoption of project-based teaching in higher engineering education to accelerate teaching mode reform.","PeriodicalId":47933,"journal":{"name":"International Journal of Emerging Technologies in Learning","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46599105","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}

The researchers used ChatGPT to obtain some academic texts and paragraphs in different genres as responses to some textbased academic queries. A critical analysis of the content of these academic texts was conducted based on the proposed framework principles. The results show that despite ChatGPT’s exceptional capabilities, its serious defects are evident, as many issues in academic writing are raised. The major issues include information repetition, nonfactual inferences, illogical reasoning, fake references, hallucination, and lack of pragmatic interpretation.

Augmented Reality (AR) is considered an efficient and promising technology capable of enhancing the educational sector. AR is a visualization technology that allows human interaction by providing users with a perception of reality using virtual information. In other words, AR adds to the existing real-world environment some extra virtual information generated by computer techniques that can enhance the overall experience. This promising technology can be applied in different sectors such as education, healthcare, banks, tourism, etc. Despite the great work available in the literature about this topic, deep insights and extensive research are still needed before the actual implementation in the real world. The aim of this work is to highlight the importance of AR in improving the educational sector and increase awareness of using such an approach. A review is conducted to prove the validity of AR in increasing learning outcomes, students’ motivation, and engagement in classrooms, as well as improving the understanding level. Several papers were analyzed based on different application areas under various interdisciplinary databases. As a result, the papers were collected in a table-based format to provide researchers with better and easier insights on how to improve the use of AR in education before real implementation. This study helped in highlighting potential future work, discussing limitations, advantages, disadvantages, and the latest advances in this technology.","PeriodicalId":47933,"journal":{"name":"International Journal of Emerging Technologies in Learning","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45850318","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}

The concept of “Internet + Education” accelerated the construction and popularization of a large number of online teaching platforms, accompanied by the emergence of various massive open online courses and online classroom teaching platforms. Thus, evaluating the teaching quality of online courses has become essential. Diversified scientific evaluations of traditional teaching fail owing to problems such as single evaluation subjects, imperfect evaluation standards, and low evaluation efficiency. In this study, first, documents on evaluation index systems and evaluation methods for identifying the teaching effect of online courses are classified, and observation points of an online course teaching effect evaluation in 16 aspects before, during, and after class are proposed. Second, the index weights are determined based on analytic hierarchy process, and a fuzzy comprehensive evaluation model is established to evaluate the online course teaching effect in six application-oriented universities in Henan Province, China. Results show that the observation points of the online course teaching effect evaluation proposed in this study are scientific and reasonable. Specifically, among the observation point indices, X-16, X-2, and X-3 have substantial weight, and the overall average score of the online course teaching effect of the case study subjects is 3.756, with a –24.88% room for improvement compared with the full score of 5.

However, its usability and impact in Computer-Supported collaborative (CSCL) learning activities that enhance students’ learning in and outside the classroom require contextual exploration. Hence, this study examined the usability and impacts of peer mentoring in CSCL among undergraduate students using a mixed-methods research approach. Data collection was conducted by administering a questionnaire with both qualitative and quantitative elements. Data analyses started with thematic coding of the nuanced texts collected through open-ended questions, and structural equation modelling (SEM) was used to analyze the quantitative data. Findings show that students have a different understanding of collaborative learning, but a common acknowledgment is that peer mentoring is beneficial in CSCL. Importantly, student views are impacted by gender, college affiliations, and CSCL experience. Drawing on the findings, we conclude that peer mentoring’s acceptability in CSCL is feasible and can affect students’ learning positively. However, it should be planned effectively and deployed based on contextual data showing students’ preference for CSCL and their peculiar need for peer mentoring.","PeriodicalId":47933,"journal":{"name":"International Journal of Emerging Technologies in Learning","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48109795","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}
