| The core of quality education lies in innovation,the core of innovation lies in thinking,and the core of thinking lies in problems.The emergence of problems depends on the cultivation of students’ problem consciousness.Cultivating students’ problem consciousness can activate students’ enthusiasm for autonomous learning and positive thinking,urge them to find problems,express them through the arrangement of key words,and finally analyze and solve them.This process can make students understand things more deeply and concretely.In the process of deepening the reform in China,the core literacy of chemistry has been put forward and paid more and more attention,and the problem consciousness plays a key role in the cultivation and development of students’ innovative ability and creativity.Classroom is the main battlefield for students to acquire knowledge.The way of activating students’ problem consciousness is gradually infiltrated into classroom teaching,which can not only highlight students’ subjectivity,but also develop students’ innovative spirit and practical ability.In high school chemistry classroom teaching,teachers’ ability to plan classroom teaching process,mobilize students’ active participation and deal with emergencies affects the generation of students’ problem consciousness to some extent.In this study,the first-line chemistry teachers in senior middle schools in C County,Y City were interviewed,and the second-year students were surveyed and interviewed,trying to understand the present situation and the degree of cultivating students’ problem consciousness in chemistry classroom teaching.This paper analyzes the questionnaire data and interview contents,and analyzes the shortcomings and reasons of cultivating students’ problem consciousness from two aspects: teachers and students.In view of the present situation of problem consciousness cultivation in senior high school chemistry classroom,combined with the corresponding theoretical research,the breakthrough of problem consciousness cultivation of middle school students in chemistry classroom is found,and a teaching model suitable for problem consciousness cultivation of middle school students in chemistry classroom is constructed.Choose Chemistry Elective Course 3 to integrate the established model for teaching design and enter the classroom practice.Through the observation and analysis of students’ classroom performance,the statistical analysis of the changes of students’ chemistry scores before and after practice,and the analysis of whether the changes of students’ scores are related to the teaching mode,it is concluded that the constructed teaching mode will have a positive impact on the cultivation of students’ problem consciousness,especially for students in key classes,which can effectively promote their learning efficiency and activate their urgency of generating problems.It can also promote the students in ordinary classes to some extent,but it needs to adjust the number and difficulty of the tutorial,the arrangement of group discussion and the speed of classroom teaching.I hope this study can promote the cultivation of students’ awareness of chemical problems,activate students’ initiative in autonomous learning,cultivate students’ core literacy in chemistry,and create an efficient classroom. |
