Instructional Technique Question Application in Stage of Deciding in Project Based Learning to Increase Score Concept Map

The study aimed to improve the concept map score through the application of instructional techniques questions in stage of deciding the study group way of collecting data and data analysis in project based learning. The research subjects consisted of 34 high school students. The study is a Class Action Research with three cycles, including: planning to develop lesson plan and its completeness, implementation of actions, observations, and reflections. Data collection is done by observation, assessment to calculate the concept map score, interviews, and documentation. Data validation uses triangulation techniques: verification of suitability of concept map scores and documentation based on expert concept maps and interviews. Data analiyzed used qualitative descriptive conducted by data reduction, data presentation and conclusion drawing based on complete data concept map. The results of the study showed that the instructional technique of the questions in the deciding the study group the way of collecting data and data analysis stage on project based learning increased the students’ concept map score of students.
