The study utilized a mixed method research design. Quantitative data were gathered using the quasione group pre-test-post-test experimental research design using the validated researcher-made instrument name Students Biological Conceptual Understanding Test (SBTU) covering the 6 biology topics for Grade 7. Qualitative data were gathered utilizing the constructivist grounded theory involving constant comparative analysis of data from varied sources. The participants of the study involved the randomly selected 40 Grade 7 STE students of a National High School situated in the Division of Passi City enrolled in the school year 2018-2019. A total of 240 mind maps were created but only 6 mind maps for each topic were taken for analysis. The results of the data analysis revealed that initially, students had an “average” conceptual understanding. The Posttest result showed that participants exposed to mind mapping strategy has improved conceptual understanding from “average” to “high”. There was a significant difference in the conceptual understanding of the students prior to and after exposure to mind mapping strategy. Utilizing constructivist grounded theory through constant comparative analysis, students revealed how they understand biological concept. Students further understand biological concepts by provoking their creativity, critical thinking, encouraging collaboration, developing their communication skill.
