The results of an earlier empirical research study on modifying 'step-by-step' instructions to practical activities requiring one or more steps of the experiments to be designed by students initiated a longitudinal study to investigate the effectiveness of the approach for younger students and over a period of time. The longitudinal study that…

The present study employed a quasi-experimental design to assess a computer-based tool, which was intended to scaffold the task of designing experiments when using a virtual lab for the process of experimentation. In particular, we assessed the impact of this tool on primary school students' cognitive processes and inquiry skills before and after…

Well-designed "controls" distinguish experimental from non-experimental studies. Surprisingly, we found that a high percentage of students had difficulty identifying control experiments even after completing three university-level laboratory courses. To address this issue, we designed and ran a revised cell biology lab course in which…
