The meeting was presided over by Rola Chen, a researcher. First, Mr. Yang Jianguo gave a class demonstration, the theme of which was the review of function synthesis in grade three. This class revolves around several teaching and research points. First, how to lead the teaching of basic function concepts with question strings; second, how to use the properties and images of functions flexibly to improve the ability to solve problems; third, how to use function knowledge to solve problems in real life. Teacher Yang's class is solid and efficient. In order to let students master the definition and concept of functions more comprehensively, Mr. Yang uses a small loop and quick feedback method to ask questions at different test sites for each type of function, helping students sort out knowledge points, encouraging students to express their ideas and methods, and for representative questions, allowing students to learn from each other and further develop. Finally, through the teacher's promotion and summary, students' thinking is greatly activated.
Secondly, it introduces the lesson of teacher Wang Ling in Changtai Middle School. The topic is the first chapter review lesson of the second day of junior high school, the proof of triangle. In this class, Mr. Wang fully studied the textbook, starting with an example of the textbook, constantly revising it, step by step, and increasing the difficulty in turn. Each lesson is taught by students first, and then questions, exhibitions and exchanges are made to learn from each other's strengths. Finally, under the guidance of teachers, difficult problems are further solved to give full play to students' subjectivity and creativity. Different from the traditional mathematics classroom, there are a series of problems in Mr. Wang's classroom, which test the teacher's classroom control ability and teaching plan design ability. How to make each link have both internal mathematical logic and a chapter of knowledge points so as not to miss anything? Teacher Wang gave us a good demonstration.
Finally, under the organization of teacher Chen, the teachers exchanged classroom comments. The first link is that the research group of the ninth grade class evaluated the lesson of teacher Yang Jianguo, and teacher Jing Beifang of No.47 Middle School conducted a teaching material analysis. Teacher Jing introduced the position of function, the content of investigation, the way of setting questions and the scores over the years, and summarized three goals for students to master this content. After listening, teachers have a clearer understanding of the investigation of function content. Teacher Zheng of Qingdao Second Experimental Junior Middle School made a concise evaluation from the aspects of classroom presentation, student feedback and teacher guidance process, pointed out the highlights of Teacher Yang's classroom, and gave pertinent suggestions, that is, the evaluation language should be rich, specific and accurate, and at the same time, simple questions should be avoided. Mr. Zhou Yajuan, the sixth middle school of the eighth grade research group, made a detailed evaluation of Mr. Wang Ling's classroom presentation, after-class reflection and student performance, praised Mr. Wang's classroom for infiltrating mathematical thoughts from special to general, and also gave two suggestions: First, there should be a strict proof process for the proof questions; The second is to pay attention to students' problem-solving thinking. Teacher An Chenfeng of Qingdao No.2 Experimental Middle School gave a teaching material analysis on the first chapter of grade eight. From the requirements of curriculum standards to the thinking of grinding teams, Mr. An explained to the teacher how the lecturer led the students in thinking and methods.
In the second part, Mr. Li Ming, a teacher from No.28 Middle School, made a detailed analysis of the scope of investigation on the content of quadratic function in grade nine and the test sites in recent years and those that did not appear. Teacher Sui has accumulated a lot of written materials and collected a lot of pre-test prediction questions. The teachers have gained a lot, and Teacher Chen has also given great affirmation to their work. Song Xiao, a teacher of Mao Zhe in No.42 Middle School, and Song Xiao, a teacher of No.23 Middle School, respectively gave a detailed introduction to the review course arrangement and the content of the senior high school entrance examination. Teacher Chen pointed out that with the reform of the senior high school entrance examination, the eighth grade mathematics teaching has attracted much attention, and every teacher should actively prepare for the changes in the senior high school entrance examination.
? At the end of the seminar, Mr. Rola Chen made an in-depth summary of today's meeting. She particularly stressed that in the future, it is necessary to strengthen the teaching discussion in the eighth and ninth grade mathematics classroom. She hopes that teachers will implement practical and effective teaching strategies for different knowledge modules, broaden their horizons, increase their knowledge and accumulate experience, and make full preparations for the reform of the new senior high school entrance examination.
