In a unit of the electrical field in high school basic physics, for the electricity flowing through the parallel circuit, it is sometimes difficult for students to explain a phenomenon from the idea of the distribution of electricity, and an understanding of the combined resistance to capture the entire circuit. In order to improve the present situation, this study developed a lesson employing teaching schemes in science learning to promote students’ self-regulated learning, and implemented the lessons. In addition, this study analyzed the class from points of views of four scenes: “Extending the idea of pre-learning”, “sharing and examining, borrowing ideas”, “expansion and modification of the concepts of the electrical field I”, “expansion and modification of the concepts of the electrical field II”, and “elaboration of the concept of combined resistance”, and examined the usefulness of the teaching design developed in this study by assessing students’ selfregulated learning in the process of instructional learning. Results showed that students perceived electricity flowing in parallel circuits from the perspective of the “voltage” and “synthetic resistance”, organized existing concepts, rebuilt the process of development of the concept of combined resistance by self-regulated learning using models themselves made. Therefore, the study shows that students have learned conceptions of combined resistance by self-regulated learning.
