| Starting from the core concepts of the discipline,the advanced learning research designs a coherent and gradually in-depth learning path,promotes the continuous development of students’ cognitive thinking,and has the important significance of promoting the scientific understanding process and the integration of curriculum,teaching and evaluation.The learning content of the course of elements and their compounds is known for its fragmentation and loose logic,and students’ learning often cannot grasp logical clues and is biased towards memory learning,resulting in confusion in thinking and inability to transfer knowledge to apply to solve real problems.In view of this phenomenon,this study takes metals and their compounds as the object and takes the advanced theory of learning as the guide to carry out the teaching design and practical research of metals and their compounds,hoping to provide a certain reference for solving this problem.This paper first sorts out and analyzes the content requirements and academic requirements of "metals and their compounds" in the junior and senior high school curriculum standards,and finds that the spiral rises in both the knowledge content requirements and the students’ ability requirements,and the course standards also reflect obvious advancement in the division of academic content requirements and core literacy levels.Therefore,this paper integrates the content of the textbook based on the curriculum standards to construct an advanced learning framework on "metals and their compounds".On the basis of the content analysis of "metals and their compounds" in the compulsory high school chemistry course 1 and the analysis of students’ development,and guided by the advanced model,the teaching design of units such as "sodium and its compounds" and "iron and its compounds" was designed,and teaching practice was carried out in experimental classes.In addition,in order to investigate the practical effect,a pre-test questionnaire and a post-test questionnaire were compiled to test students’ learning level,and through the comparison results of the experimental class and the control class,it was found that the experimental class showed obvious superiority in the test results after advanced teaching.Therefore,it can be considered that the advanced learning theory can be applied to help students improve their thinking and improve their problem-solving ability,and the application of advanced learning in subject teaching can also provide certain reference and reference value for curriculum development,textbook development,academic evaluation and other fields. |
