Coding can be defined as logical structures in which rules for processing data in a computer environment are given in an ordered form in the form of commands. The algorithm creates the logical structure of the generated code. Therefore, the coding process begins with the introduction of the algorithm The aim of this study is to determine the effect of Project-based algorithm training with Flowchart 3.0 visual programming tool on coding attitudes, problem solving skills and computer thinking skills in secondary school students. The study group consisted of 30 students. Project-based algorithm training with Flowchart support was provided to the experimental group students. In the control group, same topics are explained with paper-pencil activities. Sequential explanatory design was used in this research, which was designed according to the mixed research approach. The research data were collected using the computer thinking skill levels scale, the attitude scale for coding, the perception scale for problem solving skills, and the interview form. According to the findings, it was determined that Flowchart supported project-based algorithm training did not significantly contribute to students' perceptions about computer thinking skills, coding attitudes, and problem solving skills. Despite this, it was determined that students' thoughts about experimental activities were positive.
