Floating and sinking (FS) is a key topic in science education, both at primary and secondary levels. The interpretation of FS phenomena, however, is challenging due to the difficulty of the scientific concepts and explanatory models involved (e.g., density, buoyancy), along with students' everyday experiences, which conflict with scientific explanations. Consequently, many studies over the last few decades have investigated how FS could be taught effectively to students of different ages while utilizing multiple teaching approaches. This meta-analysis summarizes findings from 69 intervention studies on teaching FS conducted between 1977 and 2021. Over all studies, we estimated a mean effect size of g = 0.85 (95% CI = 0.71, 0.99). This large effect size demonstrates that, although FS is a challenging concept, teaching FS is effective even in elementary school. Moreover, in a moderator analysis, we investigate the effect of intervention characteristics, students' age, as well as study design, and assessment features on the mean study effect size. To analyze the effect of these moderator variables, we use a three-level hierarchical meta-regression model for dealing with multiple effect sizes from single studies. We found two intervention characteristics that explain variance in study effect sizes: longer lasting interventions result in larger effect sizes and interventions where hands-on experiments are applied are more effective than those utilizing virtual experiments. Furthermore, studies with a treatment-control group comparison have significantly smaller effect sizes than studies with a pre-post design. We discuss the implications of our findings regarding the moderator variables for effective teaching of FS and further research on FS. 相似文献

This article examines two current issues from the perspective of a librarian in a Russell Group university: the increasing importance attached to the development of teaching and learning in a research-led university, particularly the “integrated learning environment” and developments in e-research and management of the resulting “data deluge.” The role of the librarian and the need for collaboration and coordination are stressed. 相似文献

The faculty protest at the University of Michigan against the war in Viet Nam, because it seems typical of a “new activism,” provides material for a case study of the rhetorical sophistication of this and similar movements in which academic people may be involved. 相似文献

AbstractGiven that graduate employment is a clear outcome of education success, there is an urgent need to conceptualize course design strategically to maximize students’ chances of employment. In this paper, we present an Australian case study in which we used a structured career information literacy learning approach to build employability in a biological sciences capstone course, through collaboration between the university library, academics, and career service. We report the context, method, measurement, outcomes of collaboration, and roles of contributors in this partnership. This case study lends itself to potential ways of incorporating career information literacy into an academic context. 相似文献
