Abstract: This study investigated the effectiveness of the Design Thinking Process (DTP) in enhancing Grade 11 students' conceptual understanding of geological processes and Earth's internal heat and explored their experiences during its implementation. An explanatory sequential mixed-methods design was employed with 48 Grade 11 General Academic Strand students from two intact sections. Twenty-four students received instruction through DTP, while 24 students were taught using a traditional lecture-based approach. Quantitative data were collected using a validated 30-item conceptual understanding test administered before and after the intervention. Qualitative data were obtained through semi-structured interviews with 12 students from the experimental group. Results showed that both groups improved following instruction, but the DTP group obtained a higher mean gain (7.50) than the control group (3.58). The difference in learning gains was statistically significant, t = 4.20, p < .001. The DTP group also achieved a significantly higher posttest mean (23.54) than the control group (19.46), t = −3.409, p = .001. The qualitative findings generated five themes: (1) adjusting emotionally to learning geological processes through a student-centered approach; (2) reconstructing the meaning of learning science through actively constructing knowledge; (3) deepening conceptual understanding of Earth's internal heat and geological processes through experiential engagement; (4) developing collaborative and scientific problem-solving competence through negotiating and teamwork; and (5) experiencing contextual challenges while recognizing the long-term scientific value of DTP. These findings indicate that DTP supported not only conceptual learning but also active knowledge construction, learner independence, experiential engagement, collaboration, and problem-solving. However, students also experienced challenges related to emotional adjustment, time management, workload, and group participation. The study concludes that DTP is a promising student-centered approach for teaching complex Earth Science concepts when supported by adequate time allocation, teacher scaffolding, clear expectations, and structured collaborative activities.
