(2) picking up knowledge points;
(3) subdividing the examination points and the knowledge points into proper particles so that the examination points and the knowledge points are in one-to-one correspondence or many-to-many correspondence (for example, an examination point A corresponds to a knowledge point a or an examination point A corresponds to a knowledge point a and a knowledge point b), so that the books and the book contents correspond to the knowledge points, and the examination question contents correspond to the knowledge points; with respect to "particles", such as a certain point of interest or knowledge is: "skilled determinant calculation". Under the knowledge point, 3 subdivided knowledge points or examination points exist, if the examination point or the knowledge point is clearly described by 1 page of paper in the book, the examination point or the knowledge point is not required to be subdivided into 3 subdivided knowledge points generally, however, if the 3 knowledge points are very important, an expert or a system analysis deems that the description needs to be separately subdivided, the examination point or the knowledge point can be subdivided into 3 knowledge points, if the examination point or the knowledge point is not subdivided, the granularity is large, and if the examination point or the knowledge point is subdivided, the granularity is small;
(4) matching the examination points with the knowledge points;
b) measuring change of learning condition of user through examination, exercise and reading duration
(1) Different weights are set for different dimensions, including reading, practice and examination, for example, reading is set to 10% of the weight, practice is set to 30% of the weight, and examination is set to 60% of the weight; the weight ratio of reading, practice and examination can be set into different ratios according to the self needs, and is not limited to the weight ratio method;

ii, a user customizes to make a multi-dimensional quadrant graph according to the standard of the content examination frequency and the mastery ratio consistent numerical value of the knowledge points, as shown in fig. 3, a plurality of quadrant graphs with different colors can be determined according to the number of the knowledge points, and different point positions are marked in each quadrant according to the frequency and the mastery ratio of different knowledge points in the quadrant graphs; different quadrant graphs such as a four-quadrant graph, a six-quadrant graph, a nine-quadrant graph and the like can be drawn according to different amounts of knowledge points (in fig. 3, different knowledge points are not labeled with specific positions, and the specific positions need to be determined according to the frequency of the knowledge points appearing in the test by the user and the mastery ratio of the knowledge points by the user, so that the specific labels are not available);
e) the user can select to watch the contents marked by different colors through the quadrant graph, and the user only selects to watch the contents in the quadrant A, so that the user wants to read the knowledge points which are not skillfully mastered but appear at high frequency during assessment, and the learning can generate the highest benefit. Such as: the user selects to only see the content of the C quadrant, which shows that the user may want to make a missing supplement, and the user usually knows enough knowledge points and wants to go to the next floor, so that the overall mastery degree is improved. Of course, the user may also choose to view knowledge points in multiple dimensions simultaneously. When the user chooses to see the knowledge points of all dimensions, the reading is the same as reading through a book.
The books, practice problems and examination papers in the steps are all electronic versions, the computer or the mobile phone or the mobile tablet is used as a carrier, different ground colors can be marked on the books, practice problems and examination papers after the computer or the mobile phone or the mobile tablet is connected with a network, the knowledge points with the same ground color are screened out for gathering, the knowledge points are determined by expert teachers or question giving teachers, and the existing electronic book software is referred to for carrying out bookmark marking and screening on the same font.
The weight ratio of different dimensions of reading, practice and examination can also be 20% for reading setting, 20% for practice setting and 60% for examination setting (the weight ratio of reading, practice and examination can be set according to the requirements and is not limited to the weight ratio method); referring to (5) in step b), the calculation formula is as follows:
if the mastery degree of the user in the reading dimension is 0.9, the mastery degree of the user in the practice dimension is 0.8, and the mastery degree of the user in the examination dimension is 0.75, the mastery condition of the user in the knowledge point a is 0.9 × 0.2 (weight ratio of reading) +0.8 × 0.2 (weight ratio of practice) +0.75 × 0.6 (weight ratio of examination) ═ 0.79;
the weighting ratios of different dimensions of reading, practice and examination can be selected by expert teachers or question-giving teachers or the user himself.
