There are many kinds of notes, such as class notes (divided into key points and class notes), after-school notes, after-school notes and so on. As the saying goes, a good memory is not as good as a bad note, so that scattered knowledge can be put away to form a knowledge chain and a knowledge network, which is conducive to consolidating and digesting what you have learned, broadening your horizons, expanding your thinking, supplementing teaching materials, breaking through the limitations of the classroom and being more conducive to future review. (1) Do a good job in class notes: The contents of class notes are mainly the difficult and important issues explained by the teacher, such as important historical concepts, historical viewpoints, important conclusions, general laws and special cases of historical development, the knowledge framework and clues of the teacher's blackboard writing, thoughts, feelings and difficult notes in the process of listening to lectures, and many other contents. It is by no means to write down every word the teacher said and every word written on the blackboard. This is actually neither necessary nor possible. Because taking notes can't affect the class, you should write quickly when taking class notes, and the historical nouns and concepts should be as simple as possible. For longer sentences, you should grasp the main abbreviations or keywords of the sentences and define some special simple symbols instead of words, which can save time. (2) Take notes after class. Collating notes after class are collating class notes, which can be supplemented, modified and improved on the basis of the original notes, and can also be reprocessed. It is actually a process of reviewing, understanding and consolidating knowledge, which can receive better review and consolidation effect. (3) Take notes after class. In the information age, knowledge update is accelerated, but the amount of information provided by our textbooks and classrooms is limited. Therefore, students should make full use of existing resources and means (library, media, network, etc.). ) acquire new historical knowledge through various channels. This is also very important for us to study history, broaden our horizons and knowledge, cultivate multi-directional thinking, comprehensively analyze and treat historical phenomena, and thus make up for the shortcomings of textbooks and classroom teaching. Taking notes after class is to sort out the information collected through various channels, so as to further understand the teaching materials and grasp the academic views and trends. The importance of how to review after class is self-evident. The following are some suggestions on how to review after class: (1) There are some unsolved knowledge blind spots in class, and the seemingly incomprehensible knowledge is vague. After class, you should review and solve it in time and eat it thoroughly. You can read textbooks, look up information, find some related exercises, or discuss with classmates or consult teachers to find solutions. (2) After class, we should organize the class notes in time and study the teaching materials repeatedly. (3) Do some historical exercises properly, and feedback whether you have really learned, how much you have learned, and to what extent you have learned, so as to check and fill the gaps in a targeted manner. (4) Being good at summarizing and sorting out historical knowledge and building a historical knowledge system can be carried out from three aspects: macro, meso and micro. 1. Macroscopically, we should grasp what major historical events a unit (chapter) consists of, what are the internal relations between these major historical events, and what are the relations between these major historical events and the basic characteristics of its historical stage. Let's take the first chapter as an example to illustrate. The first chapter consists of seven sections and describes three major historical events, namely the Opium War, the Second Crow War and the Taiping Heavenly Kingdom Movement. The title of this chapter reveals the basic characteristics of this historical stage: China began to become a semi-colonial and semi-feudal society. The internal relations between the three historical events and the title of this chapter are as follows: (1) The Opium War made China a semi-colonial and semi-feudal society; The Second Opium War was the continuation and expansion of the Opium War, which deepened the semi-colonial and semi-feudal degree of China. The Opium War intensified the already sharp class contradiction in China and accelerated the rise of the Taiping Heavenly Kingdom Movement. After the Second Opium War, the open collusion between Chinese and foreign reactionary forces accelerated the failure of the Taiping Heavenly Kingdom Movement, which broke the attempt of the great powers to colonize China quickly. 2. In the middle view, we should grasp the elements of major historical events, that is, what we should know about this historical event. Take the Taiping Heavenly Kingdom as an example, I should know something about the Taiping Heavenly Kingdom Movement. The historical background, rising and developing process, results and reasons, lessons, nature, main historical achievements, characteristics and reasons of the Taiping Heavenly Kingdom Movement. Microscopically, we should grasp the relevant knowledge points of the elements of major historical events, and take the background of the Taiping Heavenly Kingdom Movement as an example to grasp the following contents: root cause: intensification of stage contradictions (1) external cause: direct cause of foreign capitalist aggression: serious natural disasters.
