Exploration of Chemistry Teaching in Junior High School Focusing on the Core Literacy of the Subject:Taking “Chemical Properties of Acids” as an Example
Abstract Taking the acid chemical properties as the carrier, the knowledge is carried on the superior position and the deep integration, the core knowledge, the learning activity and the evaluation are closely combined, with the help of the complete scientific inquiry, this paper applies the thinking mode of “the combination of macro and micro symbolic representation” to improve the understanding of the thought of “composition determines nature, nature determines use”, and to cultivate advanced thinking and innovative ability. An overall thinking model of “recognizing material based on category under the dominant angle of element composition and particle type” is independently constructed to realize the advanced angle of material chemical property recognition. The focus covers the subject knowledge, accumulates the subject core literacy, carries out the subject education junior middle school chemistry teaching, realizes the connection between junior high school and senior high school.
