This study investigated students' perceptions of argumentation by using Argumentation Perception Test. The sample was 245 high school students. The results showed that while practical activities were found as the most used activity in argumentative discourse, role play was the least one. Most students were found to feel themselves enthusiastic for participating in an argumentation discourse. Students' perceptions' of argumentation were based on knowledge, classroom activities, understanding, nature of science, actions by teachers and students, and classroom management. This study contributes to the evidence base for understanding the connection between students' argumentation perceptions and their improved engagement in argumentative discourse.
