Thiết kế và sử dụng video ngắn trong dạy học nội dung “Chất và sự biến đổi của chất” (Khoa học tự nhiên 8) nhằm phát triển năng lực nhận thức khoa học tự nhiên cho học sinh

Tóm tắt

This study investigates the design and use of short videos as multimedia learning materials to develop Grade 8 students’ natural science cognitive competence in teaching the content “Substances and Their Transformations”. Given its abstract and complex nature, this topic requires effective visualization to support learning. The study proposes a six-step procedure for developing short narrative-driven videos (1-5 minutes) and examines their impact on students’ natural science cognitive competence. The study designed and implemented an experimental teaching intervention using short, narrative-driven videos across two pairs of 8th-grade classes at two secondary schools in Hanoi. The experimental results reveal that students in the experimental group achieved higher academic performance compared to those in the control group, with a statistically significant difference (p < 0.01). The pedagogical experiment demonstrated evident progress in the manifestations of natural science cognitive competence, indicating that the integration of short, story-based videos significantly contributed to enhancing students' learning efficacy. The findings confirm the potential of short videos in innovating Natural Sciences teaching methods toward a competence-based educational approach for students in the digital era.
