Thiết kế bài tập thực nghiệm trong dạy học Hóa học 10 nhằm đánh giá năng lực tìm hiểu thế giới tự nhiên dưới góc độ Hóa học cho học sinh

Tóm tắt

In the 2018 General Education Program, the competency to explore the natural world from a chemical perspective is one of the three components of chemical competence that needs to be formed and developed in students. This research uses a mixed-method approach, combining theoretical analysis and expert consultation. The research results have developed 10 criteria for evaluating the ability to explore the natural world from a chemical perspective and proposed a 5-step process for designing experimental exercises. The proposed process is illustrated through the design of 25 experimental exercises in teaching Chemistry 10. Consultations with 42 experts and chemistry teachers showed that 97.6% agreed or completely agreed on the scientific validity, pedagogical soundness, and usability of the developed experimental exercise system. The results of this paper contribute to supplementing the theoretical and practical basis for reforming assessment in chemistry teaching, oriented towards developing students' qualities and competencies.
