Effects of Generic and Subject-Didactic Teaching Characteristics on Student Performance in Mathematics in Secondary School: A Scoping Review

<p style="text-align: justify;">Research on instructional quality has been of great interest for several decades, leading to an immense and diverse body of literature. However, due to different definitions and operationalisations, the picture of what characteristics are important for instructional quality is not entirely clear. Therefore, in this paper, a scoping review was performed to provide an overview of existing evidence of both generic and subject-didactic characteristics with regard to student performance. More precisely, this paper aims to (a) identify both generic and subject-didactic characteristics affecting student performance in mathematics in secondary school, (b) cluster these characteristics into categories to show areas for quality teaching, and (c) analyse and assess the effects of these characteristics on student performance to rate the scientific evidence in the context of the articles considered. The results reveal that teaching characteristics, and not just the instruments for recording the quality of teaching as described in previous research, can be placed on a continuum ranging from generic to subject-didactic. Moreover, on account of the inconsistent definition of subject-didactic characteristics, the category of ‘subject-didactic specifics’ needs further development to establish it as a separate category in empirical research. Finally, this study represents a further step toward understanding the effects of teaching characteristics on student performance by providing an overview of teaching characteristics and their effects and evidence.</p>

An Evaluation of YouTube Videos as a Surgical Instructional Tool for Endoscopic Endonasal Approaches in Otolaryngology

Objectives Online surgical videos are an increasingly popular resource for surgical trainees, especially in the context of the COVID-19 pandemic. Our objective was to assess the instructional quality of the YouTube videos of the transsphenoidal surgical approach (TSA), using LAParoscopic surgery Video Educational Guidelines (LAP-VEGaS). Methods YouTube TSA videos were searched using 5 keywords. Video characteristics were recorded. Two fellowship-trained rhinologists evaluated videos using LAP-VEGaS (scale 0 [worst] to 18 [best]). Results The searches produced 43 unique, unduplicated videos for analysis. Mean video length 7 minutes (standard deviation [SD] = 13), mean viewership was 16 017 views (SD = 29 415), and mean total LAP-VEGaS score was 9 (SD = 3). The LAP-VEGaS criteria with the lowest mean scores were presentation of the positioning of the patient/surgical team (mean = 0.2; SD = 0.6) and the procedure outcomes (mean = 0.4; SD = 0.6). There was substantial interrater agreement (κ = 0.71). Conclusions LAP-VEGaS, initially developed for laparoscopic procedures, is useful for evaluating TSA instructional videos. There is an opportunity to improve the quality of these videos.

University students experience the COVID-19 induced shift to remote instruction

The COVID-19 pandemic required an abrupt shift from face-to-face to online instruction for many students in higher education in the United States. Prior research has raised some concerns about both equitable access to online courses, and the quality of instruction in online courses compared to face-to-face courses. This survey study included a retrospective pretest approach to comparing students experiences before and after the transition to online instruction. The sample of 1731 students ranged across all available topics of study and all class standings from first-year students to doctoral students at a R1: Doctoral Universities—Very High Research Activity university according to the Carnegie classifications. Quality of instruction was addressed through the three principles of Universal Design for Learning. Students reported that most areas of quality of instruction were poorer after the transition, with having Engagement dropping by the largest effect size. However, Representation showed a small effect of improvement following the transition. Students who preferred online instruction reported less loss of instructional quality. Similarly, students eligible for disability services also reported less loss of instructional quality. Doctoral students reported significantly poorer access on multiple measures compared to all four years of undergraduate students’ standings. Results are discussed in terms of patterns, exceptions, effect sizes, and recommendations for future research.

Development of Virtual Laboratory Simulation: e-SCILAB on Waves for Grade 7 Science

Virtual Laboratory Simulation (VLS) enhances student understanding, retention of concepts, and promotes active learning through direct visualization and manipulation of computer animations. This study aimed to develop a VLS with complementary manual for Grade 7 physics that can be utilized by the teachers to address the needs of the students in the new normal learning. The developed VLS is composed of a Teacher’s Instructional Manual and Student’s Learning Manual. The study used Research and Development approach with the ADD (Analysis, Design, and Development) model as the instructional method. These allows the researchers to analyze the need of VLS, identify the design of VLS, and develop the VLS. The VLS was evaluated based on the content quality with a mean of 4.68, technical quality with 4.65, and instructional quality with 4.57. The results for the complementary activity manual in terms of the content quality is a mean of 4.62, the technical quality with 4.54, and the instructional quality with 4.55. The result showed that the developed VLS together with the complementary activity manual satisfied the quality components and attained the intended standards. It is recommended that evaluation of the effectiveness of VLS through pilot tests in public and private schools.
