The aim of this intervention study is to investigate the use of concept maps as a pedagogical tool to promote discussions around subject-specific concepts in history education. Additionally, the study seeks to explore students' experiences with using concept maps. The intervention study is implemented with fourth-grade pupils. 

 This study answers the following questions:

 ·      In what ways can concept maps facilitate discussions around subject-specific concepts?

·      How do pupils experience the work with concept maps?

·      What is the relationship between the collected material and pupils' experiences?

The intervention study employs a Lesson Study approach and incorporates two qualitative methods: observations, group interviews, and analysis of both first and second text-talk sessions between nine pupils in two groups. The study's theoretical framework is based on concept maps, participation, and interaction. Participation has been divided into three different levels based on the collected material to facilitate the analysis. The levels of participation in the study are categorized as follows: at the first level, pupils remain silent and passively attend the conversation, offering no personal input or opinions. Moving to the second level, pupils engage to varying degrees, sometimes affirming others' ideas without expressing their own. Finally, at the third level, pupils actively contribute to the discussion by sharing their own thoughts, expanding on others' ideas, and engaging in reciprocal dialogue.

The results showed that integration of concept maps increased the students' understanding and discussion around subject-specific concepts. They could connect different concepts and analyze their relationships, indicating an improvement in their conceptual understanding and knowledge. The pupils' enhanced engagement, supported by positive experiences with concept maps, is further confirmed by discussion observations. This correlation between student experiences and collected material supports the study's credibility.This underscores the significance of concept maps as a pedagogical tool for advancing understanding of subject-specific concepts in history education.
