This action research aimed to aid the issue by utilizing concept map as instructional tool to improve the understanding of students specifically in Data Analysis as a lesson in Practical Research 1. This study was conducted in a private school. There were 35 students as population of the study. Furthermore, this study utilized a qualitative approach. Data was collected through observation and in-depth interviews. The study began with identifying a learning competency in the K-12 curriculum which the students find very difficult during the second semester in Grade 11. Moreover, a lesson was designed, utilizing concept map as instructional tool for the activity. 7 students were included in the post interview. As a result, it was found out that the concept map is an effective instructional tool to improve the understanding of Data Analysis as lesson in Practical Research 1. The effects of concept map on their understanding were organized ideas, easier understanding, and improved understanding. Majority of the students also agreed that concept mapping is an effective instructional tool to improve the understanding of Data Analysis as a lesson in Practical Research 1. Lastly, an action plan is proposed for future use.
