Study (n=62) at suburban community college tested method of conceptual change in which treatment students worked in small cooperative groups on tasks aimed at eliciting their misconceptions so that they could be discussed in contrast to scientific conception that had been taught in direct instruction. Treatment group had significantly lower…

This study quantified possible changes in the classroom learning experiences of high- and low-ability pupils, which might accompany an organizational change from streamed to mixed-ability classes for science learning in secondary schools. Deteriorations in the quality of the classroom interactions of both high- and low-ability pupils were found.…
