Research On Cultivating High School Students’ Awareness Of Chemical Evidence Reasoning Based On ATDE Model

In recent years,the documents promulgated by the Ministry of Education and the new curriculum standards for chemistry have clearly mentioned "core literacy".Evidence reasoning is an important part of the core literacy of chemistry,it plays a key role in improving students’ scientific inquiry literacy.The ATDE model adheres to the principle of "student-centered",and four basic links of "Asking","Thinking","Doing" and "Evaluation" complement each other and revise each other.It can effectively develop the initiative of students to carry out inquiry learning,so as to achieve the effect of cultivating and developing students’ awareness of evidence reasoning more effectively than the traditional teaching model.This paper explores the basic teaching model for cultivating high school students’ awareness of evidence reasoning through ATDE model,which consists of three parts.Firstly,a large number of literatures related to ATDE model and evidence reasoning awareness are studied,and the research purpose and significance of this paper are proposed.Secondly,under the support of corresponding theories and student learning conditions,the research idea of ATDE model to cultivate high school students’ awareness of chemical evidence reasoning are designed.The teaching principles of the ATDE model are put forward,the implementation points of each link of the model in teaching are expounded,and corresponding teaching cases are designed from the perspectives of experimental knowledge and theoretical knowledge.Finally,taking the teaching design of "Sodium Carbonate and Sodium Bicarbonate" as an example,the teaching practice is carried out in the experimental cl ass.Through self-evaluation,mutual evaluation and teacher evaluation,it is concluded that under this model of teaching,students’ classroom participation is high,learning effect is good,and cooperation ability is strong;The classroom observation scale is used to evaluate students’ interest attitude,observation and evidence acquisition ability,thinking and viewpoint building ability,reasoning and drawing conclusion ability,it is concluded that students have high learning interest,good learning attitude and high awareness of evidence reasoning under this model of teaching;According to the analysis of the post-test data of evidence reasoning awareness,monthly test scores and achievement data,it is concluded that the ATDE model is suitable for cultivating students’ awareness of chemical evidence reasoning,developing students’ core literacy levels,and improving students’ chemistry scores.Due to the limitation of practice time and practice content,the selected samples and empirical content are few,and continuous practice research is required to obtain more reliable conclusions.
