Helping students better understand how scientists reason and argue to draw scientific conclusions has long been viewed as a critical component of scientific literacy, thus remains a central goal of science instruction. However, differences of opinion persist regarding the nature of scientific reasoning, argumentation, and discovery. Accordingly,…

D. Klahr and M. Nigam (2004) make a case for the superiority of direct instruction over discovery learning in students' mastery of the control-of-variables strategy central to the scientific method. In the present work, we examine acquisition of this strategy among students of the same age as those studied by Klahr and Nigam, as well as follow…

This study compared two groups of high school biology students and teachers with respect to teaching method and resultant behavior, learning climate, and achievement. The use of an open-inductive method yielded significantly different results from the traditional deductive method of instruction. (JR)

Compared effect of six instructional strategies (discovery, two expository lessons, prototype development, interrogatory, and combination of interrogatory/prototype development) on concept learning of college students (N=230). Results suggest use of prototype developmental method alone or in combination with interrogatory method if high levels of…

Discusses five instructional strategies for increasing the meaningfulness of technical or scientific information. These include organization of prose, use of concrete analogies as advance organizers, use of inserted questions in prose, elaboration activities such as note-taking and discovery learning. (JN)

Discusses the nature of science as inquiry, differentiating between "science as inquiry" and "teaching/learning by inquiry." Provides evidence of confusion existing among teachers on the notion of inquiry and offers practical suggestions to teacher educators to help teachers better understand inquiry and to use the method in…

Reports on a study to determine the interaction effects of selected personality characteristics, science achievement, and two classroom climates, one which encouraged discovery learning and one that did not. Demonstrated that student achievement is influenced by dynamic interactions within classrooms. (TW)
