Functional Teaching Based On Bloom’s Theory Of Classification Of Educational Objectives

Function is the main line running through high school mathematics learning,is the focus of students’ learning,but also the difficulty of teachers’ teaching.Based on Bloom’s taxonomy of educational objectives,this study explores the status quo of students’ cognitive level and emotional development on functional topics,and designs effective teaching strategies combining the development laws of the two.This paper adopts literature research,questionnaire survey and interview method.Firstly,we refer to relevant literatures to understand the teaching status of functions and the research status of Bloom’s educational classification theory in mathematics teaching.Secondly,based on the cognitive domain and emotional domain of Bloom’s educational objective classification theory,the cognitive level framework of students’ cognitive level about function and emotional level is established,and the teaching objectives of one subject and two functions are detailed in detail.Finally draw some high school students of a school in quanzhou region compulsory subject study present situation investigation and analysis,a function test test high school students about the function the cognitive level of the status quo,analysis of the problems existing in the students in the learning process,supplemented by interview outline,understand a student in learning function change of emotion,attitude and values.Draw research conclusions:（1）most of the students can understand the concepts of function and nature,to grasp the method of simple to solve the problem of function,but less flexible use function to solve practical problems,the corresponding bloom cognitive hierarchy level,students about function of cognition can only implement the memory,understanding and application of the three lower levels of level,analysis the cognitive level and above the effect is not significant.（2）Students’ cognitive goals are closely linked to the development of their emotions,attitudes and values.The higher their cognitive level is,the better they can shape their learning character and form correct values.（3）There are certain problems in students’ learning function,such as inadequate understanding of concepts,inflexible application of problem-solving methods,incorrect learning motivation and inappropriate learning habits.Based on the research conclusions,the teaching strategies are put forward:Teachers should（1）Implement Bloom’s classification theory of educational objectives in the teaching,guiding function teaching goal setting（2）pay attention to the integrity of the teaching,strengthen the close relations between 3 d object（3）attaches great importance to the thought method,promote the development of mathematics core literacy（4）implementing heuristic teaching,cultivate learning motivation and learning habits（5）advocating cooperation and differentiating teaching,to cultivate interest in learning.（6）Integrate mathematical culture into the classroom to cultivate students’ good learning quality.
