Abstract: Teaching difficulties refer to the key points that students have great difficulties in teaching and hinder their learning. If these teaching difficulties are not solved well in teaching, it is difficult to achieve good learning results, and students' learning interests will be affected, seriously affecting classroom teaching efficiency and students' learning efficiency, In teaching, teachers should base on the actual teaching and students' actual level, according to the requirements of the new curriculum standard, preset the breakthrough of students' difficulties in classroom teaching, and improve the efficiency of geography classroom teaching. This article talks about the effective ways to break through the difficulties in high school geography teaching through examples.
Key words: high school geography; Classroom teaching; Difficulties breakthrough
Geography teaching in senior high school is a difficult point in liberal arts teaching in senior high school. Difficulties in geography teaching are important factors that affect geography teaching in senior high school. This paper discusses the finding of difficulties and teaching breakthrough in geography teaching in senior high school from the perspective of teaching practice, hoping that through our explanation, students can master all the contents of geography teaching in senior high school, Realize the teaching goal of more comprehensive and systematic mastery of senior high school geography knowledge, and also improve students' ability to solve problems through breakthroughs in key and difficult points. In teaching practice, we summarized the following key and difficult breakthrough methods:
1、 Dredge one's mind
Teachers of any subject need to go from easy to difficult, step by step. In senior high school geography teaching, teachers should peel the skin layer by layer, step by step, and guide students' thinking with strict logic. In learning, clear thinking can achieve easy learning, avoid confusion and scattered knowledge, which is conducive to students' further learning and improvement of learning ability. Teaching case 1: "The influence of pressure zone and wind zone on climate" and the determination of climate type are one of the difficulties in geography teaching in high school. This content is arranged in the content of Geography (compulsory course 1) in high school. The determination of climate type is an important basis for other related geography teaching knowledge, one of the key points in geography teaching, and one of the difficulties for students to learn, In all kinds of examinations, there are endless questions about climate types. When students encounter such questions, they often do not know how to start, and it is difficult to accurately understand and make judgments. In this type of questions, the most common indicators are temperature, precipitation and other indicators to judge climate types. In teaching, teachers should recognize the northern and southern hemispheres and heat zones according to the temperature changes through the climate precipitation column and temperature curve according to the students' actual conditions, and use the precipitation provided by the topic to judge the specific climate type. In teaching, we summarized the methods of judging the northern and southern hemispheres by the month of temperature change, determining the heat zone by the temperature change, and determining the climate type by the precipitation, In this way, students' thinking is clearer, and it is easy to learn and master in teaching, which is helpful for students to learn this part of the content.
2、 Break up into parts
In the face of more difficult problems, teachers can cut and divide difficult problems into small ones. Students can start from small ones, understand some of the small problems, and then gradually solve all the small problems one by one. The small ones will grow into big ones, and finally solve the big problems and knowledge points. In this way, the teaching difficulties will be easily solved, and the learning process will be smooth and natural, In geography teaching, the method of "breaking up the whole into parts" can be used to read maps, understand small geographical concepts, understand large geographical laws and master geographical principles. Teaching case 2: In the section "Air movement caused by uneven heat and cold" arranged in the compulsory course 1 of the People's Education Press of Geography in high school, the principle of wind formation is one of the teaching difficulties. In order to help students understand the principle of wind formation through understanding the various forces of horizontal atmospheric flow, we can try to set such questions as: what is the direct cause of wind formation, what is the pressure gradient, is the pressure gradient the same as the horizontal pressure gradient, and what is the difference? Judgment of wind direction. What force does the wind have, and whether all winds are affected by these forces. These three problems go from simple to deep, and gradually let the school understand the principle of wind formation from different levels. When the above three problems are solved, students will have a clear understanding and understanding of the principle of wind formation
