| Deep learning is a kind of educational concept and learning way that caters to the development of the new era.Deep learning is a meaningful learning process that students can actively participate in,immerse themselves in,and develop their higher-order thinking.The thought of balance is an important thought in high school chemistry,which is mainly embodied in the four equilibria.The four equilibria are difficult knowledge in high school.Based on the concept of deep learning,this study will conduct teaching research and practice with the knowledge related to the four equilibria as the carrier,in order to help chemistry teachers promote the deep learning of students’ thoughts of balance through the relevant concepts of deep learning.The background of this study is the requirement of deep learning for the development of The Times,the requirement of the core quality of chemistry subject in the new curriculum standard and the important position and value of the thought of balance in chemistry subject.This paper firstly combs and summarizes the relevant theories of deep learning and balance,and clarifies the connotation of deep learning and balance.Then,guided by Dewey’s thought of "learning by doing",Bloom’s cognitive goal classification theory,Biggs’ SOLO classification theory and Ausubel’s meaningful learning theory,and starting from three dimensions of "affective domain","cognitive domain" and "skill domain",a questionnaire of four balanced deep learning for senior high school students is designed.In addition,teachers were interviewed to understand the cognition and teaching situation of teachers and students in the four equilibria.Through data analysis of the deep learning students’ questionnaire,it is found that there are three deficiencies in deep learning: first,the initiative and critical ability of learning are insufficient;Second,the ability to solve practical problems is insufficient;Thirdly,students’ cognitive processing mode is at the shallow level.Through teacher interviews,it is found that teachers do not know enough about the concept of deep learning,and deep learning teaching is needed in the actual classroom.Based on the investigation of the current situation,this paper puts forward five teaching strategies to promote the balanced thought of high school chemistry deep learning: situation experience;deep thinking;four-fold representation strategy;application of information technology;combination of multiple evaluation.Then,this study presents three typical teaching cases in teaching practice: chemical balance,water ionization balance and correlation calculation,precipitation dissolution balance,and the teaching strategies of deep learning are reflected in the teaching cases.In order to test the teaching effect,two parallel classes were selected in H middle School,and the pre-test and post-test of balanced questions were conducted on students in the experimental class and the control class.It was found that the deep learning of the experimental class achieved certain effects,and the middle students and the underperforming students made great progress. |
