Hiệu quả của dạy học dựa trên tìm tòi (Inquiry Based Learning) trong phát triển năng lực tìm hiểu thế giới tự nhiên cho học sinh: Một nghiên cứu bán thực nghiệm với môn Hóa học ở trường phổ thông

Tóm tắt

The 2018 general education curriculum emphasizes the goal of developing students' competencies; however, implementing effective teaching methods and building assessment tools for these competencies remains a major challenge. The study was conducted to verify a specific pedagogical solution in Chemistry, which is to evaluate the effectiveness of inquiry-based learning (IBL) in developing students' competency to explore the natural world from a chemical perspective through two topics: “Chemical reaction rate” and “Chemical equilibrium”. A quasi-experimental design with 76 students was conducted, using a highly reliable assessment tool (Cronbach's Alpha > 0,70) built on the SIC competency framework. The results showed that, after ensuring initial equivalence between the two groups (p > 0,05), the experimental group demonstrated significantly superior performance compared to the control group after the intervention (t(63,13) = 9,723; p < 0,001), with a very large effect size (Cohen's d = 2,204). The results confirmed the feasibility and high effectiveness of IBL in meeting the requirements of educational innovation.
