| With the continuous deepening of education reform,the Ministry of Education No.2 "Opinions on Promoting the Reform of Comprehensive Evaluation of the Quality of Primary and Secondary Education"document put forward: "to establish a comprehensive evaluation index system,improve and perfect teaching methods,improve teaching efficiency,reduce students’ excessive workload.BOPPPS model is student-oriented,carefully designed teaching links and improved classroom efficiency,while chemistry learning self-efficacy focuses on students’ moral character,physical and mental development level and academic burden,which meets the requirements of evaluation reform in primary and secondary schools.Through the integration of BOPPPS model and chemistry learning self-efficacy,it is expected to help students improve their learning belief and ability and promote the reform of comprehensive evaluation of education quality.Based on self-efficacy theory,dialogism theory and activity theory,this research is carried out through literature research,questionnaire survey,classroom observation,educational experiment research and interview.Firstly,this paper summarizes and analyzes the BOPPPS model and learning self-efficacy theory at home and abroad,understands the research status of the two,and defines "BOPPPS model","learning self-efficacy theory" and "chemical learning self-efficacy".Secondly,by developing evaluation tools such as "Questionnaire on the Status Quo of self-efficacy in Chemistry Learning","Classroom Observation Scale" and "Subject Test Volume",the preliminary investigation was carried out by questionnaire survey,and the reliability and validity test and comprehensive analysis of the questionnaire data were carried out to diagnose the current level of students’ chemistry learning.Then,combined with the actual situation and characteristics of the BOPPPS model,the cultivation strategy of chemical learning self-efficacy based on the model was proposed.Six cases were selected and designed from the first and second volumes of high school Chemistry Compulsory course of Human Education Edition(2019),and the teaching practice was carried out in two classes with no significant difference,and relevant data were collected.Finally,through the comparative analysis of the changes in the learning self-efficacy of the experimental class and the control class,and the experimental class in the early and late stages,relevant conclusions are drawn.The research shows that it is feasible and effective to use BOPPPS model to cultivate high school students’ self-efficacy in chemistry learning,which has a significant promoting effect on improving their belief and ability in chemistry learning,developing their self-efficacy in chemistry learning and cultivating their interest in learning,and effectively highlighting the dominant position of students and teachers in class.In terms of the cultivation of self-efficacy in chemistry learning,the theme of "inorganic compounds" has the best effect on the cultivation of students’ exploration and cooperation ability. |
