A steadily adopted educational practice is technology-mediated non-interactive teaching, in which students generate explanations of the previously learned contents to a fictitious audience by means of technologies (e.g., video, messenger). Although recent laboratory studies documented benefits of non-interactive teaching, field-oriented evidence is scarce. Research is needed to examine how laboratory evidence applies to authentic learning environments with school students and to determine whether these effects are generalizable to different authentic contexts. We applied a ManyClasses study to a) examine the generalizability of technology-based non-interactive teaching and b) explore context-related (domain, school type), demographical-related (age, gender, language), and implementation-related (grading, medium, timing) boundary conditions. In collaboration with teachers, we realized <em>k</em> = 20 different teaching units (each consisting of two lessons) in authentic settings across various school types and domains. Using a within-participants design, school students (<em>N</em> = 191) either taught the previously learned contents by means of technology to a fictitious peer or retrieved the contents in mind after the lesson. Results showed no main effect of non-interactive teaching; but domain and school type moderated the learning activity. The findings indicate that non-interactive teaching is not effective per se, but rather depends on the instructional contexts in which it is implemented. The investigation of the teaching effect with new approaches allows, for the first time, more generalizable conclusions to be drawn about non-interactive teaching with technology for students in authentic settings.</div></div>","PeriodicalId":100322,"journal":{"name":"Computers and Education Open","volume":"7 ","pages":"Article 100233"},"PeriodicalIF":4.1,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142656561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This knowledge is essential to the consideration of whether to continue, modify, or cease this form of course delivery. Therefore, the aim of this scoping review was to fill this gap in the literature by exploring the experiences of university instructors and students with the HyFlex model via a scoping review that followed Arksey and O'Malley's scoping review framework. A thematic analysis approach was used to analyse the data from each study reviewed. Four key themes emerged from the analysis: (a) learning satisfaction, (b) benefits of the HyFlex mode, (c) barriers and challenges related to the HyFlex mode, and (d) external factors that influence the quality of teaching and learning in the HyFlex mode. Each of these is discussed in detail and implications for future practice and further research directions are considered. The review also uncovered that there is a dearth of studies that included the voice of instructors, hence highlighting an underresearched area regarding the HyFlex mode of instruction.</div></div>","PeriodicalId":100322,"journal":{"name":"Computers and Education Open","volume":"7 ","pages":"Article 100229"},"PeriodicalIF":4.1,"publicationDate":"2024-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142528368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To explore this, we examined government upper primary and secondary school teachers’ experiences of participating in a course entitled ‘Constructivist teaching and learning with technology within the TPACK framework’ (CTLT), which was offered to over 500 teachers in 23 districts in the Indian state of Assam. Based on the survey responses of 209 (pre-course) and 109 (post-course) teachers, the findings of the study indicated that, contrary to expectations and much current scholarship, the female teachers significantly outperformed the male teachers in terms of course completion. However, the teachers who undertook the survey in English performed better than those who did so in Assamese.

Therefore, we developed a theoretical model of MAU, its determinants, and its consequences. By utilizing a free simulation experiment, we investigated the role of MAU in the domain of mobile learning. We used structural equation modeling to analyze the theoretical model. The results show a significant influence of MAU on mobile learning compatibility, performance expectancy, and self-efficacy. The results also indicate that compatibility acts as a partial mediator of usability on performance expectancy. Finally, we conducted an importance-performance analysis that reveals key usability insights: UI output, the most critical factor, underperforms, highlighting a major improvement area. UI structure and application design also need enhancement. In contrast, UI input and application utility perform well despite lower importance, with UI graphics showing adequate performance despite being least crucial.
