Thiết kế và sử dụng bộ thí nghiệm khảo sát hợp lực song song trong dạy học Vật lí 10

Tóm tắt

Physics is an experimental science; practising experimental skills will help students discover the properties and laws of nature as well as test the correctness of theoretical knowledge. The main means of practice are experimental sets with full features, helping teachers to use, exploit, and convey pedagogical ideas in lessons to achieve the objectives of the subject. In the 10th grade physics program, teaching the content of knowledge about parallel forces is difficult with current equipment, leading to learners having difficulty in solving the problem of finding the characteristics of the resultant force (direction, magnitude, point of application). This study points out the limitations of using current experimental sets and has designed a new experimental set to examine parallel forces that can support teachers in the process of organizing cognitive activities in the direction of developing competence, promoting positivity, autonomy, and creativity for learners. In the process of teaching physics 10, teachers should use the new experimental set flexibly based on specific teaching conditions to improve teaching effectiveness.
