Research On The Teaching Practice Of High School Logarithmic Functions From The Perspective Of Core Literacy

In the context of the new curriculum reform,in order to implement the fundamental task of Lide Shuren and cultivate socialist builders and successors with all-round development,the Ministry of Education put forward the core literacy of Chinese students to develop.The core literacy of students needs to be gradually formed through the teaching of specific disciplines,so as to reflect the educational value of each discipline,that is the core literacy of disciplines.The cultivation of core literacy in mathematics is of great significance to promoting the all-round development of students.At the same time,the improvement of core literacy in mathematics disciplines also plays a vital role in mathematical learning.The knowledge of functions is strongly integrated,and it can comprehensively reflect the core literacy of mathematics disciplines.As an important part of the function,the logarithmic function contains rich mathematical ideas and methods,and is a good carrier for the development of the core literacy of the mathematical discipline.In this study,the research methods such as literature research method,questionnaire survey method and interview method are used to propose the teaching strategy of logarithmic function from the perspective of core literacy,and to carry out teaching design and teaching practice.The main contents are as follows:First,280 high school students in a high school in H City were surveyed to understand the students' knowledge mastery,emotional attitude and core literacy development in the process of learning logarithmic functions,and 5 teachers were interviewed to understand the difficulties in the teaching of logarithmic functions and the implementation of the core literacy of mathematics.The results show that students lack self-confidence,lack of interest and poor habits in the learning of logarithmic functions,and the students' knowledge of logarithmic functions is not solid enough,and their mathematical ability related to logarithmic functions is lacking.In the teaching process,the implementation of core literacy is not ideal,and teachers need to pay more attention to the cultivation of students' core literacy in mathematics.Second,the teaching content of the logarithmic function is analyzed,and based on the results of the current situation survey,the teaching strategy of the logarithmic function from the perspective of core literacy is proposed:(1)attention to ability and process,adjust the direction of teaching objectives and teaching evaluation;(2)integrate into history and step by step,stimulate students' learning interest and confidence;(3)innovate methods and optimize activities to promote the development of students' core literacy.Third,according to the teaching strategy,the corresponding teaching design is given and implemented,and then the effectiveness of teaching is tested.The results show that the mastery of logarithmic functions in the experimental class is better than that of the control class,indicating that the teaching strategy from the perspective of core literacy plays an important role in helping students master knowledge and improve their abilities.Through the reflection on teaching practice,teachers need to pay attention to the following four points in the teaching of cultivating students' core literacy in mathematics disciplines:(1)closely follow the core literacy and analyze the teaching materials in depth;(2)attach importance to ability orientation and set goals reasonably;(3)pay attention to ability improvement and optimize teaching activities;(4)pay attention to the learning process and evaluate students in a pluralistic way.
