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 indeed some seemingly simple but confusing questions in primary school mathematics. For example, the problem of repairing bricks. The existence of half a brick might confuse the child. It was necessary to observe the arrangement of the bricks, first calculate the number of bricks in a complete row, then calculate the number of bricks in the empty row, and then use the number of bricks needed in each row to subtract the number of bricks in the empty row. Finally, the number of bricks in each row was added to get the total number of missing bricks. The question of knowing the direction was a test for the spatial thinking ability of the third grade children. When the spatial imagination ability was limited, they could use children's songs to remember the method of direction judgment. The process of solving equations using the properties of equations was long and tedious when they first started learning. Although the shifting method was short, it was easy to make mistakes. There were also calculation problems that included a variety of situations, such as the first grade addition and substitution calculation method, the memorization of multiplication pithy formula, and the proficiency in three-digit multiplication of one-digit numbers, two-digit divisions, decimals, and simple calculations. In addition, questions like A multiplied by B equals 16, A multiplied by A equals 8, and B multiplied by B needed to be solved by finding the relationship between A and B. There were also controversial questions about the concept of repeating decimals, and different people would get different answers. These questions might be difficult for primary school students, but for graduate students, due to their long-term exposure to advanced mathematics knowledge, when faced with these questions with unique elementary school logic, they might also be difficult to answer. <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>

From the information provided, there was no clear indication of the specific content of the 2021 primary school to junior high school mathematics questions. However, it can be seen that there are core test points for mathematics in 2021, including the understanding of numbers, such as the uniqueness of "0" in the integral part.(In positive and negative numbers, 0 is the dividing point; in natural numbers,"0" is the smallest natural number but not the smallest one-digit number, etc.), multiple and factor (there are countless common multiple of several numbers, 1 is the common factor of all non-zero natural numbers, etc.), the oddity of numbers, prime numbers and composite numbers (the smallest prime number is 2, the smallest composite number is 4, etc.), and the concept of cardinal number and serial number may be the key points. In addition, the two basic mathematics calculations and application questions were mandatory. There were also 60 classic "Golden Motives" that were mandatory. The application questions were all evolved from these questions, but the specific questions were not given. The analysis of the key questions in mathematics also involved knowledge points such as the understanding of numbers. At the same time, after the review in 2021, the students had a better understanding of the scope and question types of the primary school entrance examination. This also hinted that the question types involved in the review process were more important parts, but it did not specify the content of the compulsory questions. Therefore, he couldn't accurately give the 2021 primary school to junior high school math questions. <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>

The following are some ideas and examples that are suitable for the first grade mathematics question setting competition: ** 1. Computational Propositions ** 1. ** Basic addition and multiplication ** - Proposition example: Xiao Ming has three candies, and his mother gave him two more. How many candies does Xiao Ming have now? - Proposition idea: Through simple life scenes, test the students 'understanding of addition within 10. 2. ** Increase and decrease ** - Proposition example: There are five birds on the tree. Three flew over first, and then two flew away. How many birds are there on the tree now? - Proposition idea: Combining dynamic scenes, students are required to perform addition operations first, and then subtract operations to test their initial mastery of the concept of continuous addition and deduction. ** 2. Comparisons ** 1. ** Comparing the quantity ** - Proposition example: Given two sets of graphs, the first set has four triangles, and the second set has six circles. Which set has more graphs? - Problem-setting idea: intuitively let the students compare the number of two different sets of shapes, and test their understanding of the concept of quantity and the ability to compare sizes. 2. ** Comparisons of length and height (combined with images)** - Proposition example: Draw two line segments, one 5cm long and the other 3cm long. Which line segment is longer? Or draw two children, one tall and one short, and ask who is taller? - Proposition idea: Start with intuitive graphs to test students 'understanding of length, height, and other comparison concepts. ** 3. Understand the proposition of diagrams ** 1. ** Pattern recognition ** - Proposition example: Give some common shapes (such as square, triangle, circle, rectangular) and mix them together. Ask the students to circle all the triangle shapes. - Proposition idea: Test the students 'ability to recognize basic patterns. 2. ** Diagram Combination and Disintegration ** - Proposition example: What shape can be formed by two triangulations? (The answer is either a rectangular or a quadrilateral.) - Proposition idea: A preliminary test of the student's spatial imagination of graphic combinations. ** IV. Propositions about the composition of numbers ** 1. ** Digital Understanding ** - Proposition example: 12 is made up of () tens and () ones. - Proposition train of thought: Investigate the students 'preliminary understanding of the concept of numbers, namely the meaning of ten digits and one digit. 2. ** Number breakdown ** - Proposition example: 7 can be divided into () and ()(The answer is not unique, such as 3 and 4, etc.) - Proposition train of thought: Understand the students 'mastery of the concept of decomposition of a number. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following are some of the main points for writing a review of the primary school mathematics competition: ** 1. Teaching objectives ** 1. ** Clarity of goals ** - Check if the teaching objectives are clear, specific, and in line with the curriculum standards and the students 'reality. For example, was it purely focused on imparting knowledge and skills, such as letting students master a certain mathematical calculation method, or was it also a goal that took into account the process and methods, emotional attitudes, and values? For example, while teaching mathematics knowledge, they should focus on cultivating students 'logical thinking ability (process and method) and interest in mathematics (emotional attitude and values). 2. ** Target Achievement ** - Consider whether the students can achieve the pre-set teaching goals at the end of the class. It could be judged from classroom practice, students 'answers to questions, and homework. If it was a calculation class, it would depend on the students 'calculation accuracy in class practice; if it was a concept understanding class, it would depend on whether the students could accurately explain the relevant concepts and apply them to solve practical problems. ** 2. Teaching content ** 1. ** Accuracy of content ** - Make sure that the teaching content is accurate. No matter if it's a mathematical concept, theorem, or example, there can't be any mistakes. For example, when explaining the area calculation of a geometric figure, the application of the formula must be accurate. 2. ** Depth and breadth of content ** - To analyze whether the depth of the teaching content is suitable for the age and learning level of the students. For primary school students, the content should not be too profound and difficult for them to understand, nor should it be too simple and not challenging. At the same time, the breadth of the content should also be moderate. It should cover all aspects of the knowledge. For example, when teaching the understanding of scores, not only should the concept of scores be explained, but also the comparison of scores, simple calculations, and other related content. 3. ** The content is coherent and logical ** - The organization of the teaching content should be coherent. From the introduction to the teaching of new knowledge to the consolidation of practice, the transition between the links should be natural. For example, from reviewing old knowledge to introducing new knowledge, the explanation of the new knowledge should be carried out in a logical order from shallow to deep. For example, first talking about integral multiplication, then extending to decimal multiplication. Logically, it should be a step-by-step relationship. ** 3. Teaching methods ** 1. ** Multiple methods ** - Observe whether the teacher uses a variety of teaching methods. For example, in addition to the traditional teaching method, were there any intuitive teaching methods (such as using teaching aids to show geometric figures), group cooperative learning methods (allowing students to discuss and solve mathematical problems in groups), inquiry teaching methods (guiding students to explore the laws of mathematics independently), etc.? The combination of multiple teaching methods helps to meet the needs of students with different learning styles. 2. ** Method effectiveness ** - Judge whether the teaching method is effective in promoting students 'learning. For example, in the group cooperative learning method, it depended on whether the members of the group actively participated in the discussion and whether the problem was solved through cooperation, rather than being a formality. For the inquiry-based teaching method, it was necessary to analyze whether the students really understood the mathematical knowledge in the process of inquiry, rather than the teacher directly telling the answer. ** 4. Teaching process ** 1. ** Introduction Stage ** - A good introduction should be able to attract the students 'attention and stimulate their interest in learning. It could be introduced through interesting mathematical stories, mathematical phenomena in life, or challenging mathematical problems. For example, when teaching statistics, one could import statistics from the height and weight of the students in the class. 2. ** New teaching segment ** - Whether the teacher's explanation was clear during the new teaching process. Whether the key knowledge was emphasized, and whether the difficult knowledge was cleverly resolved. For example, when teaching solving equations, shifting terms was a difficult point. Did the teacher use examples to let the students understand the basis and method of shifting terms? 3. ** Practice session ** - The design of the exercises had to be targeted and could consolidate the knowledge learned. The difficulty of the practice had to be graded, from basic practice to extended practice, to meet the needs of students at different levels. For example, after teaching the multiplication formula, the basic practice could be a simple multiplication formula filling in the blanks, and the extended practice could be solving the multiplication problem in real life. 4. ** Wrap-up segment ** - Whether the teacher had effectively summarized the knowledge of the class at the end of the class, whether it could help the students sort out the content and form a knowledge system. At the same time, whether there was simple feedback and evaluation of the students 'learning situation. ** 5. Teacher Quality ** 1. ** Teaching posture and language ** - The teacher's teaching attitude should be friendly and natural, infectious, and able to create a positive classroom atmosphere. The teacher's language should be accurate, concise, and vivid, and avoid using overly complicated or vague expressions. For example, when explaining mathematical concepts, the language must be precise and not ambiguous. 2. ** Class organization and management skills ** - Observe whether the teacher can effectively organize the classroom teaching and maintain good classroom order. During group activities or class discussions, it can guide students to actively participate and avoid classroom chaos. At the same time, they were able to deal with unexpected situations in the classroom in a timely manner, such as unexpected questions raised by students or disciplinary issues. 3. ** Smart teaching ** - Whether the teacher has teaching wit and can flexibly respond to various situations in the classroom. For example, when a student gave a wrong answer, could the teacher cleverly guide the student to discover the error and correct it? Or when the teaching plan could not be carried out according to the original plan for some reason, could the teacher adjust the teaching strategy in time? ** 6. Student performance ** 1. ** Participating Rate ** - Pay attention to the students 'participation in the class, including their enthusiasm in answering questions and their initiative in participating in group activities. It could be measured by the number of times students raised their hands to speak, the activity of participating in group discussions, and so on. 2. ** Learning Effect ** - Judging the students 'mastery of the knowledge from their classroom performance and practice completion. For example, the students 'accuracy in class exercises and whether they could use what they had learned to solve practical problems. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
