Research On Jigh School Chemistry Unit Teaching Design Under The Concept Of Deep Learning ——Taking "Atomic Structure And Periodic Law Of Elements" As An Example

With the development of the times and the reform of the new curriculum,the requirements of the society for talents are also changing.They no longer blindly pursue scores and further education.They call for talents who have core literacy and can continue to learn and innovate in the face of the changing times.Deep learning helps to promote the development of students' ability and literacy.However,The most favorable starting point is the overall teaching design of the unit.Based on this,the author proposes to study the unit Teaching Design under the Concept of Deep Learning,in order to promote students' deep learning and provide some reference value for teachers' deep teaching.The research background comes from the call for talents in the new era,the urgent need of curriculum reform and the development of chemistry teaching practice.Then,it reviews and combs the relevant literature such as deep learning and unit teaching design,defines the characteristics,connotation and significance of deep learning,puts forward the significance,purpose,content and methods of research,and summarizes the concept,specific route and function of unit teaching design.With the guiding ideology of Bloom's Educational Goal Taxonomy Theory,Metacognitive Theory,Constructivist Learning Theory and UBD Theory,this paper designs a questionnaire on Senior One Students' chemistry in-depth learning and a questionnaire on the current situation of teachers' classroom teaching,so as to understand the current situation and problems of chemistry classroom teaching.Based on this,this paper further analyzes the four key elements of unit teaching design under the concept of deep learning:(1)establish a leading unit learning theme,(2)set a literacy oriented unit learning goal,(3)create challenging learning activities,(4)formulate a continuous learning evaluation scheme.On this basis,this paper constructs the basic model of unit teaching design and puts forward five corresponding teaching strategies:(1)study teaching materials,Reconfiguration unit;(2)Combined with the learning situation,clarify the goal;(3)Create situations and promote exploration;(4)Activity driven,implement literacy;(5)Continuous evaluation,feedback and correction.According to the teaching model proposed in this paper,the "periodic law of atomic structure elements" is analyzed as a whole,and the learning theme,learning task,learning goal and evaluation scheme of the unit are established.In order to test the practical effect,two parallel classes,class 4 and class 5,grade 1 of Guilin Guolong foreign language school,are selected as the research object,and the homogeneity analysis is carried out with the help of the students' first examination results.Then,a one semester teaching practice is carried out.After that,the students are given the prepared unit post test paper and in-depth learning questionnaire to test the learning effect.The results show that the teaching design model and teaching strategies proposed in this paper can improve students' ability in personal field,interpersonal field and cognitive field.However,due to the limited practice time,the author found many deficiencies in the research and reflection,which need to be further improved in the future teaching practice.The majority of teachers and scholars can selectively apply the teaching design models and strategies proposed in this paper to teaching according to the actual situation.
