Study On The Effectiveness Of Different Teaching Strategies On The Transformation Of The Concept Of Electrochemical Myth

Students through their own long-term accumulation of experience and discerning learning form a non-essential understanding of things,these understandings and scientific concepts have certain deviations,that is,the concept of myths.The concept of myth makes teachers' teaching and students' learning have certain difficulties.Therefore,it is very necessary to study the process of concept transformation and effectively promote the transformation of students' myths.There are many mythological concepts in the electrochemical content,combined with students' existing concepts of electrochemical mythology for teaching design.Selecting effective teaching strategies to achieve the conversion of students' myths into scientific concepts has become an important issue that needs to be resolved.Based on the integration of a large number of electrochemical myth concepts at home and abroad,this study combined the opinions of the tutor group and the front-line teachers to compile an electrochemical concept test questionnaire to explore the concept of electrochemical mystery for high school students and to propose an electrochemical fan after analyzing the results.The three teaching strategies of the concept transformation: cognitive conflict teaching strategy centered on problem guidance,visual multimedia computer aided instruction strategy,and the use of concept maps to strengthen the relationship between knowledge and improve cognitive network teaching strategies.The author designed the teaching around these three strategies and applied the three teaching strategies to teaching practice.Based on the results of the analysis,I found out what kind of teaching strategies are more effective in transforming the concept of electrochemical myths.The results show that there are many mythological concepts in the concept of electrochemistry in Grade 2 students,and the causes of the students' myths are complicated.The concept change process of students is closely related to the teaching strategies adopted by teachers.In the transformation of the concept of electrochemical myths,the visual multimedia computer-assisted instructional strategy is the most effective,followed by the cognitive conflict teaching strategy centered on problem guidance,and the last is the conceptual map tostrengthen the relationship between knowledge and improve the cognitive network teaching.Strategy.
