| Problems are at the heart of mathematics.Questions are an integral part of math classes,The 2017 edition of The General High School Mathematics Curriculum Standards also explicitly proposes to improve students’ ability to discover and propose problems from the perspective of mathematics,as well as the ability to analyze and solve problems(referred to as the "four abilities").Therefore,mathematics teaching in senior high school based on mathematics core literacy should be problem-oriented and based on the whole process of problem discovery,proposal,analysis and solution.In the process of problem solving,it triggers and deepens students’ mathematical thinking,it is necessary to cultivate students’ ability of logical thinking and problem solving.This research uses literature research method,questionnaire survey method and interview method to investigate some high school students and front-line teachers in Fuzhou City.To understand the current situation of problem-oriented teaching implementation supported by technology in high school mathematics classroom,then,for teachers in teaching difficulties,the author consulted a large number of relevant literatures and integrated into constructivist learning theory,situational cognition theory,multi-representation theory,visual thinking theory,etc.,proposed a problem-oriented teaching strategy supported by visualization technology for high school mathematics.Among them,relying on "visualization technology",this paper puts forward corresponding strategies from the four main links of problem-oriented teaching: finding problems—understanding problems—solving problems—reflecting problems.It includes:(1)creating a visual situations and find problems with mathematical eyes;(2)appropriate representation of problems to facilitate problem understanding and expression;(3)appling visual operations to explore ideas for problem solving;(4)trying diversified exchanges,in-depth reflection and expansion of problems.Finally,a specific case is selected to illustrate the rationality and feasibility of the teaching strategy,in order to improve the problem awareness and problem-solving ability of high school students,and maximize the teaching quality and efficiency. |
