Xây dựng và sử dụng thí nghiệm lượng nhỏ trong dạy học chủ đề “Nitrogen và Sulfur” (Hoá học 11) nhằm phát triển năng lực tìm hiểu thế giới tự nhiên dưới góc độ hoá học cho học sinh

Tóm tắt

Currently, the use of microscale experiments in teaching Chemistry is being of interest, research and development in many countries because of its compact size, flexible movement, and small size, saving chemicals and especially reducing the amount of chemicals released into the environment to a minimum... Compared to using traditional experiments, the use of microscale chemical experiments brings many benefits in contributing to the development of chemical competence, implementing green chemistry orientation and improving learning interest for students, and at the same time saving cost and time in conducting experiments. The article presents the theoretical basis, how to build and use microscale experiments in the topic “Nitrogen and Sulfur” in Grade 11 Chemistry in order to develop the research competence to understand the natural world from the perspective of Chemistry for students.
