This study aims to search the impact of POE supported inquiry-based instruction in the unit of electricity on the academic success and scientific inquiry skills of students. The research method performed in this study, which is one of the quantitative research technics, is determined as pre-test and post-test matching control grouped quasi-experimental method. Sample of this research contains 26 students at the level of sixth grade. In the experimental group, inquiry-based instruction method and Predict-Observe-Explain (POE) method are used in teaching the unit of electricity whereas the activities of the current science curriculum are used for teaching in the control group. As data collection tool, an academic success test including 20 multiple choice questions concerning the learning outcomes of electrical conduction and the scientific inquiry skills test consisting 22 items are used. The academic success test in the unit of electricity was applied to students both in control and application groups before and after the implementation. Additionally, scientific inquiry skills test was applied on students in the experimental group before and after the instruction. Data of this study was analyzed by using SPSS Statistics 23 program. It was concluded that the academic achievement test and scientific inquiry skills test results of students in the experimental group in which inquiry based instruction is implemented are higher than results of control group. Considering these results, it was suggested that inquiry-based instruction method and Predict-Observe-Explain (POE) method should be used in science teaching because these methods can increase the academic success and scientific inquiry skill of students.
