High School Mathematics, Thought Disorder, And Teaching Strategy

Mathematics is a science of thinking. The whole process of mathematics learning and problem-solving is a thinking process. Thinking obstacle is a widespread phenomenon in the learning of middle school students,Especially in high schools. This article analyzes and summarizes the high school math thinking obstacles through questionnaires, interviews to enhance the effectiveness and pertinence of teaching constantly and to improve the students'quality of thinking. Mathematical thinking obstacle of high school students includes nine types. That is, they are cognitive thinking obstacles, narrow-thinking obstacles, thinking set obstacles, image thinking obstacles, abstract thinking obstacles, weak metacognition obstacles, thinking obstacles of transfer, thinking obstacles of skills and emotional thinking obstacles . The survey shows that girls in high school have more serious narrow thinking obstacles, abstract thinking obstacles, weak metacognition obstacles, emotional-thinking obstacles than boys while relatively boys have more serious thinking obstacles of skills than girls; the poor students have more problems in thinking set obstacles, image thinking obstacles, thinking obstacles of skills; and the poor students have more serious problems in cognitive thinking obstacles, narrow-thinking obstacles, abstract thinking obstacles, weak metacognition obstacles, thinking obstacles of transfer and emotional thinking obstacles. In the end, targeted teaching strategies are put forward to construct proper cognitive structure to overcome cognitive thinking obstacles; to develop the extensity and flexibility of students'thinking to overcome narrow-thinking obstacles and thinking set obstacles; to improve the abstract and image thinking ability to overcome image thinking obstacles and abstract thinking obstacles; to develop the metacognitive ability to overcome weak metacognition obstacles; to overcome the negative transfer and promote positive transfer to overcome thinking obstacles of transfer, to strengthen skills training to overcome thinking obstacles of skills and to promote emotional transfer to overcome emotional thinking obstacles .
