The main purpose of this study is to determine the effectiveness of the stop motion technique in improving the scientific reasoning of third grade high school students in the chemistry course with the subject of electroplating. The study sample includes 150 students, all of whom were studying in two fields of mathematics and experimental studies in the academic year of 2011-2012. The approach of this research is quantitative and the method used is quasi-experimental, of the Salomon four-group design. Also, in terms of purpose, it is among applied researches. The sampling method is cluster. This research was done with two experimental groups and one control group. in experimental group 1; Training using stop motion technique was used in an unstructured way. in experimental group 2; Training was used in a structured way using the stop motion technique. Static model was used in the control group. The sources of data collection in this study to study the breadth and depth of vision are: audio recording, step-by-step notes of the researcher, individual interviews with students.To analyze the research data, statistical methods were used at two descriptive levels (central and dispersion indices) and inferential (t-test and analysis of variance). The results showed that the use of unstructured stop motion technique has a more effective role in improving students' scientific reasoning skills than structured stop motion technique and static model.
