Research On The Units Integrity Teaching Design And Practice Of High School Chemistry Based On Deep Learning

Deep learning is the learning pointing to higher-order thinking and an important way to develop students’ core literacy in subjects.Unit overall teaching is an important to realize students deep learning,can effectively solve the problem of knowledge fragmentation,superficial,however,in high school chemistry class deep learning and the overall teaching unit research less,therefore,based on deep learning of high school chemistry unit overall teaching design and practice research is very necessary.On the basis of sorting out the relevant literature of deep learning and overall unit teaching,this study investigates and interviews the current situation of students ’deep learning and teachers’ overall implementation of unit teaching,and finds that students are at the shallow learning level,teachers have no clear understanding of overall unit teaching,and difficulties in implementing overall unit teaching.Based on this,the overall unit teaching model based on deep learning is constructed,which includes six links: analyzing teaching elements,selecting unit learning topics,determining unit learning objectives,overall planning unit teaching,designing unit learning activities and evaluation and reflection.Under the guidance of the teaching model,"iron and its compounds" is taken as an example for the overall unit teaching design based on deep learning."iron and its compounds" are divided into three class hours with internal logic,namely,the selection of iron supplement,the use of iron supplement and the test of iron supplement.The three periods surround the leading learning theme of "scientific iron supplement".In order to understand the teaching effect,two classes are selected as the control class and experimental class in a middle school in Tongliao City.The practice results show that,The post-test scores,key test scores and the completion of open homework are better than the control class students,Further analysis of the test questions found that,The overall unit teaching mode and the traditional teaching mode based on deep learning can achieve the shallow "double-base goal",But in the experimental inquiry questions with the ability of reasoning with evidence,The scores of the experimental class students were significantly higher than those of the control class,Show that the overall unit teaching model can better develop students’ core literacy,Promote the structure of knowledge;Through the completion of the open assignments,Found that the students in the experimental class have internalized what they have learned,Have the ability to transfer between knowledge;Through student interviews,it is found that the overall unit teaching based on deep learning can stimulate students ’interest in learning and develop students’ inquiry ability.To sum up,it shows that the overall unit teaching has a good role in promoting deep learning,and the overall unit teaching based on deep learning is feasible and effective.
