The aim of this study is to examine the effect of the 5E learning model designed in accordance with a techno pedagogical lesson plan on student success and attitude in a Turkish course. The research is quantitative and uses a quasi-experimental model with pre-test/post-test control groups. The universe of this study consisted of 8th grade students studying in the Onikisubat district of the province of Kahramanmaras in the 2019-2020 academic year. The sample of the study consisted of 110 students studying in four different classes from within this same population. The lessons in the experimental group were taught using a 5E learning model designed in accordance with a techno pedagogical lesson plan, while the lessons in the control group were based on the methods described by the Turkish lesson curriculum. In this study, the "Attitude Scale Towards Turkish Lessons" (ASTTL) and "Turkish Course Academic Achievement Test" (TCAAT) were used as data collection tools. In the analysis of the data obtained in the study, the independent sample t-test and the correlated sample t-test were used. As a result of the research, a statistically significant difference was found in favor of the experimental group between the average achievement scores of the students in the experimental group and those of the students in the control group. However, a statistically significant difference was not found between the average attitude scores of the experimental group versus the control group.
