Throughout the history of education, debate has existed between the relative merits of instructed versus constructed knowledge. In this article, we review our program of research in science education for students with disabilities in order to reveal some insights into this debate. We review research in science curriculum, mnemonic strategies,…

A study involving 75 elementary students, 51 with high-incidence disabilities, investigated variables associated with learning in an inquiry-oriented approach to the study of density and buoyancy. Preconceptions, scientific predictions, and academic achievement measures were not predictive of task performance. However, grade level and IQ were…

Twenty-six junior high school students with learning disabilities studied two science units via an activity-based, inquiry-oriented approach or a textbook approach. Students performed higher on immediate and delayed unit tests when they had learned by the inquiry approach, and reported a preference for this approach. Vocabulary acquisition was…

Evaluation of a sequenced inquiry learning task with 20 normally achieving junior high students, 18 students with learning disabilities (LD), and 16 with mild mental retardation (MR) found 75 percent of the normal, 50 percent of the LD, but none of the MR students made the correct induction. LD and MR students were less likely to answer…

Fifty-three adolescents with learning disabilities or mild mental retardation were taught reasons for dinosaur extinction. Those taught in a mnemonic elaborative interrogation condition recalled more reasons than did students who received direct teaching. Students in elaborative interrogation and mnemonic elaborative interrogation groups recalled…
