The transition from junior high school to senior high school was an important turning point in a student's learning career. In terms of mathematics learning, it was of great significance to reflect on the transition between junior high school and senior high school. ** I. Connection of teaching materials ** 1. ** Knowledge depth and breadth ** - The content of junior high school mathematics textbooks was relatively common and specific. Most of them were constant, and the questions were simple and close to daily life. On the other hand, high school mathematics had abstract concepts, rigorous theories, strong logic, and more difficult knowledge. There were many types of questions, and the solution techniques were flexible and varied. For example, the learning of the secondary function in junior high school was mostly shallow and mechanical imitation, while high school required a higher level of understanding and application. Moreover, the new high school textbooks did not have a separate chapter on the secondary function, which required teachers to make up for this gap in teaching and help students smoothly transition from junior high school to high school. 2. ** Knowledge structure adjustment ** - Some of the knowledge in the middle school textbooks that were often used in high school, such as exponents, solving oblique triangle, and exponents, were transferred to the first year of high school. This required teachers to plan the order and depth of teaching in advance so that students could systematically construct a knowledge system. ** 2. Connection of teaching methods ** 1. ** The difference between the teaching characteristics of junior high school and the needs of senior high school ** - Junior high school mathematics teaching content is small, difficulty is low, class time is sufficient, teachers have more time to repeatedly explain the key and difficult points, practice, teacher-student interaction is sufficient. On the other hand, high school mathematics had more knowledge points, greater flexibility, and fewer class hours. It focused on students 'independent learning and the cultivation of creative thinking. Teachers used more methods such as guidance, questioning, traps, and changes to inspire and guide students, which made students who had just entered high school unable to adapt. 2. ** Direction to improve teaching methods ** - Teachers needed to adjust the teaching rhythm at the beginning of high school and not enter the high school teaching mode too quickly. For example, when explaining new knowledge, they could review the relevant knowledge in junior high school and establish the connection between the old and new knowledge so that the students could gradually adapt to the teaching methods in senior high school. At the same time, they should pay attention to cultivating students 'independent learning ability and guide students to learn to think and answer questions by themselves instead of relying solely on teachers' explanations. ** 3. Students 'Self-adaptation ** 1. ** Mental factors ** - The students in Grade One were psychologically locked in. They would not speak or respond in class, which brought obstacles to teaching. Teachers needed to pay attention to the psychological changes of students and adopt more flexible teaching methods, such as group cooperative learning, to mobilize the enthusiasm of students and break this psychological barrier. 2. ** Learning Method ** - Junior high school students were used to being surrounded by teachers and lacked the initiative to learn, the ability to learn independently, and the ability to arrange their time in a scientific manner. After high school, it would be difficult to learn from the junior high school method. Teachers should guide students to change their learning methods, cultivate habits such as previewing, reviewing, and concluding, improve students 'self-learning ability, and let students learn to digest and adjust their own knowledge. ** 4. Cultivation of interests ** 1. ** Important ** - Interested in learning mathematics was the key. If students encountered setbacks in the early stages of high school mathematics, they would easily lose interest in learning. Teachers should pay attention to stimulating students 'interest in teaching, such as through the introduction of examples and the infiltration of mathematical culture, so that students can feel the charm and practicality of mathematics. 2. ** Strategy ** - For example, when explaining the concept of functions, they could introduce examples of functions in life, such as the change of temperature with time, the relationship between the distance of an object's movement and time, etc., to let students understand the close connection between mathematics and life, thus increasing their interest in learning. At the same time, he could recommend some books that could stimulate students 'interest in mathematics and broaden their horizons. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

There were many ways to design the primary school mathematics competition. For example, individual and team competitions could be set up. The individual competition would have a compulsory answer segment, and the team competition would have a compulsory answer segment. Each school's representative team could have a certain number of opportunities (such as two) to ask for help outside the field. The competition covered in-class knowledge such as calculations, graphics, and geometry. At the same time, it set up puzzle questions such as 24-point and Sudoku. He could also set up a computational ability test segment, including mental arithmetic, vertical calculation, off-line calculation, solving equations, etc. He could also set up a thinking question segment to test the students 'thinking ability. In addition, the Teacher Quality Competition could be composed of segment teaching, blackboard design, chalk writing, talent performance, and other parts. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following are some elementary school math problem solving techniques: 1. Drawing Strategy: Translate the words of a difficult problem into a picture. It can quickly sort out your thoughts and find a solution. In the process of solving a problem, by drawing a diagram related to the meaning of the problem, the diagram was used to help reasoning and thinking. This was especially common when solving problems such as geometry, proportions, or scores. 2. ** Transformation Strategy **: Transform a complex problem into a simple problem, and turn an unknown problem into a known problem. This is one of the common methods used to solve problems in primary school mathematics. 3. ** List Strategy (Enumeration Strategy)**: List the condition information of the problem in the form of a table. This makes it easy to find the problem and analyze the quantitative relationship, thereby eliminating the interference of non-mathematical information. At the same time, it also helps to find a solution to the problem. When using it, one must pay attention to not repeating or missing anything. 4. ** Enumeration Strategy **: When solving some special problems that cannot be calculated, it can list all possible situations of the research object, so that the problem can be solved more easily. When listing, you have to think in an orderly manner to ensure that you don't miss anything. 5. ** Substitution Strategy **: Used to solve the problem of the relationship between several quantities and the total quantity. By using this strategy, the relationship between two quantities could be simplified into one, which would help to solve the problem. 6. ** Comparing Method **: According to the meaning of the mathematics question, compare the meaning and essence of concepts, properties, laws, rules, formulas, terms, and terms. Relying on the understanding, memory, recognition, reproduction, and transfer of mathematical knowledge to solve the question. This would help train the child to have a correct understanding of mathematics knowledge, a firm memory, and accurate identification. 7. ** Comparisons **: By comparing the similarities and differences of mathematical conditions and problems, you can study the reasons for the similarities and differences and find a solution to the problem. When using it, you need to pay attention to the completeness of the comparison, find the connection and difference, compare under the same relationship, and grasp the main content to compare carefully. 8. Formula Method: Use laws, formulas, rules, and rules to solve problems, reflecting deductive thinking from the general to the special. However, it was necessary to ensure that the child had a correct and profound understanding of formulas, laws, rules, and rules, and could use them accurately. 9. ** Analysis Method **: To break down the whole into parts, to break down complex things into various parts or elements, and to study and derive these parts or elements. The idea was to start from the problem to be solved, choose the two conditions needed correctly, and deduce them one by one until the problem was solved, which was "tracing the cause from the effect." 10. ** Holistic approach **: For some calculations, when a certain part cannot be calculated directly, this part can be regarded as a whole and solved step by step. For example, when solving an equation, if there were multiple calculation steps on one side of the equal sign and a certain part could not be calculated, one could first treat this part as a whole to solve it. 11. ** Using Aptitudes **: When you encounter complex calculation problems, you can use approximate numbers to help with quick calculations. 12. ** logical reasoning method **: When solving some reasoning or logic questions, use logical reasoning to get the correct answer. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following is the general method of writing an analysis of an elementary school mathematics competition question: ** I. Overall Situation ** 1. ** Difficulty Assessment ** - Analyzing the overall difficulty level of the questions. For example, the target group of the competition (such as primary school students, senior students, etc.) could be used to determine whether the questions were in line with their knowledge and thinking ability. If it was a competition for senior students, the questions might include the application of more complex mathematical concepts and a multi-step solution process. - Considering the distribution of the difficulty of the questions, whether the overall difficulty was difficult, easy, or moderate. For example, most of the questions in a set of questions were simple transformations of basic operations. Only a few questions involved advanced thinking skills, such as logical reasoning and complex mathematical model construction. Then, the difficulty distribution could be considered uneven and the overall difficulty was low. 2. ** Knowledge Points Covered ** - He sorted out the mathematical knowledge points covered by the questions. Elementary mathematics included numbers and algebra (such as the operation of numbers, decimals, and scores, equations, etc.), graphics and geometry (such as the calculation of the area and perimeter of a triangle and a quadrilateral, the understanding of three-dimensional graphics, etc.), statistics and probability (such as data collection, sorting, and simple probability calculations), etc. For example, 50% of the questions in a set of competition questions involved numbers and algebra, 30% involved graphics and geometry, and 20% involved statistics and probability. ** 2. Question Type Analysis ** 1. ** Multiple choice question ** - For multiple-choice questions, analyze the purpose of each choice. The correct choice should be based on accurate mathematical principles, while the wrong choice was usually the typical type of mistake that students were prone to make. For example, in a multiple-choice question about decimal multiplication, the correct choice was the result calculated according to the algorithm of decimal multiplication, while the wrong choice might be the result of forgetting the movement rule of the decimal point or the wrong order of operation. - The assessment of multiple-choice questions was based on the knowledge points. Some multiple-choice questions might directly test the memory of the concept, such as "Which of the following figures is a quadrilateral (give a few graphic options)", which was an intuitive test of the concept; while others determined the correct choice through calculation or logical reasoning, such as "The result of dividing a number by 0.5 is greater than this number (A. large;B. small;C. equal;D. uncertain)", which required the student to have a deep understanding of the nature of division operations. 2. ** Fill-in-the-blanks question ** - Analyzing the characteristics of the answers to the fill-in-the-blank questions. The answer to the fill-in-the-blank question was usually unique. It tested the student's precise mastery of a specific knowledge point. For example, in a fill-in-the-blank question about the sum of the internal angles of a triangle, the student was required to fill in the degree of a certain internal angle of a triangle. This required the student to accurately use the knowledge of the sum of the internal angles of the triangle being 180° to calculate. - Consider the difficulty level of the fill-in-the-blank questions. Some fill-in-the-blank questions might only require a simple one-step calculation, such as "2 + 3=( )", while others might involve complex calculations or a deep understanding of the concept, such as "The radius of the bottom of a cylinder is 3 cm, the height is 5 cm, and its side area is () square centimeters (Pi is 3.14)". This not only required the student to remember the calculation formula for the side area of the cylinder, but also to perform the numerical calculation correctly. 3. ** Answer Questions ** - For questions, analyze the variety of solutions. Some questions might have multiple solutions, such as the competition questions related to the area of the ladder mentioned earlier. It analyzed the mathematical ideas and methods involved in different solutions, such as equal-area transformation, proportional relationship, graph division, etc. - It was to test the comprehensive ability of the students. Students often needed to apply multiple knowledge points to solve questions and be able to clearly express the process of solving them. For example, for a question about chickens and rabbits in the same cage, the student needed to first determine the method of the hypothesis (assuming that it was all chickens or all rabbits), and then calculate the number of chickens and rabbits based on the difference in the number of legs. This process involved simple algebra and logical reasoning. ** 3. Remarks and suggestions ** 1. ** Student performance prediction ** - According to the difficulty of the questions and the characteristics of the questions, predict the students 'possible performance on various knowledge points and questions. For example, for difficult logical reasoning questions, only a few students with strong mathematical thinking ability could correctly answer them. For basic calculation questions, most students should be able to score, but they might lose points because of carelessness. 2. ** Teaching suggestions ** - Based on the analysis of the test questions, suggestions were made for primary school mathematics teaching. If you find that a certain knowledge point in the test questions is more important and students may make mistakes easily, such as the mixed calculation of scores, then you can strengthen the practice and explanation in this area in the teaching. At the same time, for questions that tested the students 'comprehensive ability, it was suggested to carry out more comprehensive mathematics activities or project-based learning in the teaching to improve the students' comprehensive application ability. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
