Chemistry Teaching Based on Subject Understanding: Logic, Problems, and Development Paths

Understanding subject knowledge of chemistry refers to an original and structured understanding of the subject knowledge, ways of thinking and methods. Implementing chemistry teaching based on subject understanding is not only conducive to improving students' chemistry learning outcome, but also helps to promote the transformation of chemistry teaching methods, develop students' innovative abilities, and enhance the quality of talent cultivation. However, in the current chemistry teaching in China, there are still problems such as the low level of subject understanding among middle school chemistry teachers, the influence of the exam-oriented assessment system, and the insufficient teaching support system for subject understanding in chemistry, which has led to a less satisfactory effect of chemistry teaching based on subject understanding. To develop chemistry teaching based on subject understanding, it is necessary to optimize the teacher education system to improve teachers' level of subject understanding; practice the concept of curriculum reform and establish a teaching assessment system based on subject understanding; develop the teaching support system to consolidate the teaching foundation of subject understanding in chemistry.
