Research On Task Oriented Mathematics Teaching In Senior High School ——Take Trigonometric Function As An Example

The?General Senior High School Curriculum Standards of Mathematics 2017 Edition?(revised in 2020)advocates that learning methods should have the characteristics of independent thinking,independent learning,cooperation and communication,task oriented teaching is an advanced teaching mode that guides students to learn by doing,taking "task" as the carrier,reflecting the characteristics of participation,interaction,communication and cooperative learning.At present,the research on task-based high school mathematics teaching mainly shows in the aspects of application and significance,implementation strategies and precautions,but the case study of systematically discussing task-based high school mathematics teaching needs to be strengthened.Therefore,this paper takes the task-based "concept and significance-problems faced-implementation strategies-specific links-evaluation and enlightenment" as the idea to study,trying to provide some reference value for high school mathematics teachers to use task-based teaching.First of all,with the help of the Internet,the concept of task orientation and research status at home and abroad,sort out these materials,summarize the principles and theoretical basis of task orientation,and form a research framework.Then through the method of literature analysis and classroom observation,this paper analyzes the problems of task orientation in the current high school mathematics classroom,and puts forward three strategies: strengthening the understanding of task orientation,clarifying the main teaching contents,optimizing tasks,and paying attention to the way of introducing tasks into the classroom.Secondly,it summarizes the three steps and five links of task-based teaching proposed by Prabhu,Willis and Skehan,and designs the specific implementation process of Task-based Teaching in high school mathematics teaching from pre-class,classroom and post-class by integrating "pre-task preparation-activities in the task-feedback after the task" and "teachers clarify the task,students prepare,perform the task,task presentation and task evaluation".Then take "radian system" and "the image and nature of sine function" as cases,and draw inspiration for task-oriented teaching.Finally,the conclusion is drawn: task-oriented mathematics teaching in senior high school is a cycle process completed by the cooperation of teachers and students;The specific links of the pre-task preparation,activities in the task and feedback after the task in the distribution and implementation process of high school mathematics teaching before,in class and after class are clarified.In a word,this research can promote the development of task-based teaching in high school mathematics classroom,and the implementation of task-based teaching can promote the mutual growth of teachers and students.
