Dataset for Students' Conceptual Understanding of Direct Current due to the Use of Systematic Problem-solving Strategy

This dataset consists of one MS Excel file. The file has three sheets; the first contains pretest scores from the Inventory of Basic Conceptions in Direct Circuits (IBCDC) tool, the second contains posttest scores from the IBCDC tool, and the third contains correct answers for each item (question) of IBCDC tool. A quasi-experimental design was used, involving 152 senior five students from four Rwandan secondary schools, with 65 students in the experimental group and 87 in the control group. Both groups were administered a pre-test and post-test using the Inventory of Basic Conceptions in Direct Circuits (IBCDC) tool, which is widely recognized for diagnosing misconceptions and assessing conceptual understanding in physics. The SPPS strategy served as the intervention for the experimental group, guiding students through a structured five-step process to solve physics problems systematically.
