This study was a mixed quantitative–qualitative research to evaluate the efficacy of a designed student-centred instructional
(DSCI) program for teaching about acids and bases. The teaching innovation was designed based on constructivist, hands-on
inquiry and context-based approaches and implemented in seven 45-min lessons with a class of 36 grade 11 students (experimental
group) from a public senior high school in Indonesia. Another class of 38 students (comparison group) from the same school
was instructed using a traditional teacher-centred approach. Data were obtained using a (1) 12-item achievement test on acids
and bases that was administered to both groups as a pretest and a posttest, (2) self-evaluation 13-item questionnaire on students’
perceptions of their competence and confidence in carrying out the inquiry activities that was administered to the experimental
group and (3) 3-item open-ended questionnaire on students’ perceptions of the instructional process using the DSCI that was
administered to the experimental group. The results of the study showed that the teaching innovation was effective in improving
students’ understanding of acid–base concepts with significant difference between the two groups on the posttest mean scores.
Moreover, the effectiveness of the innovation was supported by an increase in students’ interest in learning science as indicated
by their (1) positive perceptions of their engagement and competence in doing inquiry activities, (2) positive perceptions
of the learning environment and (3) positive outcome expectations. The findings have implications for chemistry teaching in
any institution with similar achieving students as well as for the professional development of teachers. 相似文献

The coronavirus disease 2019 (Covid-19) pandemic caused an abrupt transition from face-to-face to online anatomy teaching, learning, and assessment. Although online education has ensured the continuity of anatomy education during the pandemic, its implementation has been challenging, and its effectiveness has been questioned. Therefore, literature pertinent to online anatomy education during the pandemic is crucial to explain Covid-19's disruptions to this field. Accordingly, this scoping review explored changes, disruptions, and gaps in anatomy teaching and assessment during Covid-19 using an enhanced version of Arksey and O′Malley's six-stage protocol. Five online databases were searched for articles that described changes and disruptions in anatomy education. Three independent researchers were involved in titles, abstracts, and full texts screening, while another four researchers were independently involved in data extraction, charting, and synthesis. This review revealed six themes: immediate strategic plans and actions, teaching and learning changes, online assessment practice, students' and educators' receptivity and adaptability, online learning and assessment effects, and future directions. It also revealed four gaps: non-future-ready curricula, learning obstacles, administrative and teaching challenges, and online education ethical issues. The results were reported in tabular and narrative forms, following the PRISMA Extension for Scoping Reviews (PRISMA-ScR guidelines). Understanding the evolution and gaps in anatomy education during the Covid-19 pandemic will help anatomists design future-ready, adaptable curricula. 相似文献
