Abstract

This study focuses on the design, implementation, and comparative evaluation of two different teaching and learning approaches of the Control of Variables Strategy (CVS), using Open Problems (OP) within the phenomenon of oscillations. The teaching approach of the Valid Experiments Group (VEG) emphasized the subskill IN (Interpreting), using only unconfounded experiments, while the Non-Valid Experiments Group (NVEG) focused on the subskill UN (Understanding), including also confounded experiments. The participants were 24 students in the 9th grade. After completing the instruction, the students in both the VEG and NVEG groups showed improvement in lower-level subskills but continued to struggle with the higher-level subskill UN.
