In this study, we developed a step-by-step teaching method that divides hypothesis setting into “finding variables” and “examining causal relationships.” In the finding variables stage, students are asked to find multiple variables related to an event by comparing multiple events with different variables, and to share the found variables with the class. In the examining causal relationships stage, the students are asked to organize the causal relationships among variables and then write their own hypotheses. With the aim of clarifying the effects of this teaching method, we conducted two continuous teaching practices in the unit of “Electric Current and Its Use” in the second grade of junior high school. The results supported that the step-by-step method of teaching hypothesis setting through the comparison of multiple events improved the quality of learners’ hypothesis setting skills.
