Abstract:

The teaching reform has adopted a blended teaching approach that combines online and offline methods. This approach incorporates tropical crop materials and products, such as coconut meat, coconut oil, and oil palm fruits, into the combustion heat determination experiment, which is the classic physical chemistry experiment. In the process of the experiment, the students not only mastered the measurement technology of combustion heat of three kinds of samples-solid blocks, powdered solids, and liquids, but also gained an understanding of the connotations and significance of national strategies like "Healthy China", "Rural Revitalization", and "Sustainable Development". The reform enriched the course content, enhanced students' enthusiasm for learning, and strengthened the synergistic effect of moral education during the teaching process, leading to a positive teaching outcome and demonstrating excellent potential for widespread adoption.
