High school students suffer most not from a lack of understanding in school, but from forgetting, making mistakes and making mistakes. The source is four words: knowledge fragmentation. The point of knowledge is scattered, there is no system to tie it together, and it's all mixed up. And the next five steps are to help you make the leaflets a catalogue of books that you own。
Where the hell is the debris in knowledge
High school knowledge is itself an organic whole, and there is a strong logical correlation between knowledge points, but most students are recorded in a fragmented manner. For example, the cyclical law of chemical elements, with only a "symmetrical mutation" and no reconnection to the atom structure and the extra-nuclear electronics, cannot be combined at all. Learning that is not supported by a system is like breaking a book into a pile of pages on the table that can't be found in half a day and that doesn't fit in when you want to use it。
Students with a system remember their knowledge points through logical linkages, which are three to five times more efficient than isolated deaths, and encounter complex problems that quickly extract multiple linkages from the system. In 2025, the trend towards high-level examinations became clearer, with the proportion of cross-knowledge points and cross-disciplinary combinations rising from year to year, and students with no systems were largely lucky to face such issues, and students with systems were able to secure their scores, thus opening the gap。
List of core knowledge points for dismantling teaching materials
The teaching materials are the foundation of the system, and any system that departs from them is the sky. The course of action is to break down the materials into modules by discipline, module and then divide them into four categories for each knowledge point, basic concepts, theorem formulae, regular methods and high frequency points. Using the chemical element cyclical method, for example, the underlying concept is the atomic structure and cyclical table of elements, the the theorem formula is an extra-nuclear electro-temperature pattern, the regular method is mutation of the same cycle and the hf test point is the method of decomposition of elemental inferences。
The end-of-class astrologers are focused on the order of priority, three stars are selected for advanced examinations, two stars are regularly tested, one star is known and the fire is concentrated on three and two stars. And don't forget the "thinking and discussing" and "exploring" sections of the teaching materials, which look down on them, but which are often typical examples of extension and application. Many students skip the exam without looking at it, and it's a shame to see the results of the exams。
Putting in a hierarchy makes knowledge belong
The list of knowledge points is completed, and the next step is to structure the hierarchy in a logical relationship, most commonly tree-shaped map. The main module of the subject is the root node, downward extension submodule, knowledge point, details. For example, history extends from the "old chinese political system" to "separation" to "county system" and goes into specific points like "iron ploughing" and "conservation." the order must be consistent with the underlying logic of the discipline, with history being time-lined, mathematical physics being extrapolated and biochemistry being sequenced by causal chain。
Tools such as xmind and curtains can also be used to draw thought maps and extend core concepts to the centre. The mathematical "function" node, for example, separates the "definition and nature" "preliminary function type" function from "use" three main branches, each detailing the specific concepts and formulae. The logic of drawings should be rigorous, and the irrelevant knowledge points should not be stuck under the same branch, otherwise the framework would be so busy that it would not be able to make a real problem。
Building networks through interdisciplinary linkages
Many of the knowledge points in high schools are naturally interdisciplinary, so that they can transform the system from a flat to a stereo. The combination of geographic and political issues in the context of the analysis of regional economic development should be accompanied by the mobilization of geographic "regional resource advantages" and political "economic development strategies". The combination of physics and biology and the analysis of the transport of cytomaterials are linked to the principles of physical osmosis and the membrane structure of biology。
This is done by consciously placing "interdisciplinary linkages: xx-scientific knowledge point" next to the notes, and then supplementing them with your knowledge system. After a certain amount of accumulation, new combinations can quickly mobilize a multidisciplinary portfolio of knowledge. In 2025, the percentage of interdisciplinary cross-cutting issues was generally about 15 to 20 per cent in high-level examinations in the provinces, and this is a large area of space, so that it is not easily lost。
Dynamic update system to keep up with the point of view
Knowledge systems do not simply exist, and must be continuously updated with changes in learning progress and performance. Each chapter is completed and new knowledge points are added to the corresponding framework immediately. For example, mathematics learns "conductive" and hangs it to the sub-subsidiary under the "functional" module, supplementing the definition of the conductivity, the guidance method, the application of the conductivity to the single-modular polar value. The advantage of synchronized updating is that knowledge is always "hot" to forget after a week。
At the end of each examination or major exercise, the corresponding knowledge point of the error is marked on the system with a red pen indicating the specific error-prone points. For example, it is easier to ignore the definition of domain limits in a single-modular determination of functions, with the adjoining "errorability: first definition of the field and then single-modularity". New solutions were learned, such as the "constructive function" specialization of variable proofs, with examples of applicable subject and step under the "functional application" branch and next direct call。
It's an output that changes knowledge from understanding to learning
The system's set up without output, and it's stuck in the "i think i get it." the most direct test is to tell people, try to teach them a modular knowledge point, which must be taken from the system, where the shell is, where it is not clear, and where it is, the system's loophole, to be filled. Also, a weekly summary of knowledge is written, combing the position of this week's new learning point in the system, as well as links to old knowledge, such as the transformation of trigonometric images and the nature of functions。
There is also a strong strategy to bring together every other month all teaching materials and notes, to draw independently the academic knowledge framework, to compare it with previous versions and to see if there is any omission or a logical error, and to expose weaknesses very efficiently. The system is a long-term process, from the dismantling of teaching materials to the dynamic updating and the strengthening of the output, and every step has to be patient. When the system is truly perfected, it is no longer a matter of thinking, but a voluntary call。
