Thiết kế và sử dụng web học liệu số theo mô hình học vi mô nhằm phát triển năng lực tự học cho học sinh thông qua dạy học chủ đề “Tốc độ phản ứng” (Hóa học 10)

Tóm tắt

In the current context of education in our country, digital learning materials play an important role in fostering self-study competency among high school students. In this paper, we introduce the foundation and designing process of a digital learning material system based on the micro-learning model “ChemBridge web”. Also, the researchers propose measures for its application in teaching the topic “Reaction Rate” to enhance the self-study competence of 10th-grade students. The study was conducted empirically on 196 students from two high schools in Nghệ An province to measure the results before and after the intervention. The experimental results show that the ES value is 0.79 and the independent t-test value p = 1.56 × 10⁻⁷, indicating a significant impact on students' self-study competence. The findings confirm the effectiveness and feasibility of the digital learning material system based on the micro-learning model “ChemBridge web” in developing students' self-study competence in chemistry education.
