In today's world, it is expected that individuals should develop much more comprehensive and equipped capabilities than ever before to become successful in their careers. Today, the aim of education cannot be agreed as access to information. In the center of Next Generation Science Standards (NGSS) which is demonstrated as one of the significant reforms of science education lies argumentation and applications of engineering design. The research aims to determine the influence of argumentation-supported design-based science and engineering applications on the middle school seventh-grade students' success of the interaction of light with matter. The research has been conducted with 7 graders pupil in the educational year of 2019-2020 in the second term in a maintained school in Konya. Light achievement test was applied to the experimental and control group students before and after the application. The research was carried out according to the experimental model with a pre-test post-test control group, which is one of the quasi-experimental designs. While the education was followed through the 5E learning cycle model which is the existing science teaching program with the control group, it was carried out by the argumentation supported designed based engineering practices with the experiment group in this study. t-test was used in the analysis of the data since the research data was a normal distribution. The experimental group students' light test success scores increased significantly after the application. As a conclusion of the research, it was identified that argumentation-supported design-based engineering applications increased seventh-grade students' achievement in the light subject. Students can improve their hand skills with the application. Considering the research, it is suggested that using the argumentation supported designed based engineering in science education.
