Two generative approaches to reaction mechanism instruction for novice students were compared to lecture instruction. In both approaches, students were coached to propose selected reaction mechanisms based on prior knowledge. New instructional methods were correlated with increased skill in representations of electron movements and other gains.…

Background: Increasingly, high dropout rates in science courses at colleges and universities have led to discussions of causes and potential support measures of students. Students' prior knowledge is repeatedly mentioned as the best predictor of academic achievement. Theory describes four hierarchically ordered types of prior knowledge, from…

Prior knowledge of and interest in subject matter are recognised as important factors influencing students' academic achievement and the quality of their learning experience. Teaching students who are diverse in terms of their prior knowledge of and interest in the subject matter is an oft-cited challenge in science general education courses. The…

In South Africa, foundation programmes are a well-established alternative access route to tertiary science study for educationally disadvantaged students. Student access to, and performance in, one such foundation programme has been researched by the authors seeking opportunities to improve student retention. The biology module in particular has…

Researchers and educators continue to explore how to assist students in the acquisition of conceptual understanding of complex science topics. While hypermedia learning environments (HLEs) afford unique opportunities to display multiple representations of these often abstract topics, students who do not engage in self-regulated learning (SRL) with…
