A study was conducted to quantify the effectiveness of concept maps in learning physics in engineering degrees. The following research question was posed: What was the difference in learning results from the use of concept maps to study a particular topic in an engineering course? The study design was quasi-experimental and used a post-test as a…

This study involved the evaluation of the efficacy of a planned instructional program to facilitate understanding of the macroscopic, submicroscopic and symbolic representational systems when describing and explaining chemical reactions by sixty-five Grade 9 students in a Singapore secondary school. A two-tier multiple-choice diagnostic instrument…

Identifies some of the major factors underlying common problems that students have in acquiring an understanding of chemistry concepts. Suggests and discusses the use of concept maps as an aid in ensuring that meaningful learning rather than rote learning has occurred among students. Contains 32 references. (ZWH)

Suggests that instructors can foster the growth of thinking skills and promote science literacy by incorporating active learning strategies into the classroom. Describes situations in which a variety of learning strategies were incorporated into large earth science courses for non-majors. Improvements in student achievement, retention, and logical…
