Research On The Design Of High School Mathematics Exercises Based On Core Literacy

With the continuous deepening of education and teaching reform,the position of mathematics core literacy in mathematics education has been enhanced significantly.In the mathematics curriculum standard of general high school(2017 edition),it is clearly pointed out that the core literacy of mathematics subject is the concentrated embodiment of the mathematics curriculum goal.As an important course type of deepening knowledge understanding and perfecting knowledge structure,mathematics exercise lesson should have the function of developing students' mathematics subject core quality.But in practical teaching,due to the tight teaching time and heavy task,exercise lesson is always used as a tool to lead students to solve problems,while neglecting the important function of cultivating students' core quality.Therefore,how to cultivate students' core quality in exercise lesson teaching has become a problem worthy of study.On the basis of reading a large number of literature,this paper sorts out the current research situation at home and abroad,and clarifies the background,significance and methods of the research.To investigate the teachers and students with the method of questionnaire,the main purpose is to understand the current situation and problems in senior high school mathematics exercise lesson,and to provide a realistic basis for the research of this paper.On this basis,around the development of students' core literacy,the design principles and strategies of exercise lesson are obtained.On the basis of "ADDIE" model and aiming at cultivating students' core quality,the framework of exercise design is constructed.According to this framework,the exercises in basic elementary function(I)are designed and practiced in the practice school.Finally,by analyzing the changes of students' scores,the situation of their classroom performance and the results of their interviews.We can find that the average scores of the students in the experimental class are obviously higher than those in the control class,the classroom atmosphere of the experimental class is more active,and the students' learning enthusiasm is also higher.It can be found that the students of the experimental class generally think that the learning effect is better under the new problem-solving mode.Therefore,the teaching design of exercises based on the core literacy is really helpful to cultivate students' core literacy of mathematics subject,to enhance students' interest in learning,and to improve students' ability to solve problems.
