How to use interactive feedback system to evaluate primary school mathematics learning in three stages: before class, during class and after class.
The composition of "less talk and more practice" teaching in primary school mathematics is about to pass. It can be said that the semester is coming to an end, and I am very busy and have gained a lot. On the whole, all mathematics teachers conscientiously implement the school education and teaching work plan, change their ideas, actively explore and reform teaching, and combine the new ideas of new curriculum standards with those of mathematics classroom teaching while continuing to promote the "independent-innovative" classroom teaching mode in our school to change their ideas. Actively explore and reform teaching, and achieved good results. First, the curriculum standards have entered the teacher's mind. How do we teach mathematics in class? The National Mathematics Curriculum Standard puts forward many new requirements for mathematics teaching content, teaching methods, teaching evaluation and educational values. There is no doubt that every one of our math teachers is placed in it to meet this challenge. It is a problem that every teacher must rethink. At the beginning of the semester, organize backbone teachers and teaching and research team leaders to participate in the training of new curriculum standards and new textbooks organized by the department, and participate in the research-based learning training organized by the department. On the basis of serious study in all grades, all math teachers were trained for the second time by two teachers, Huang Lina and Chen Yanhong, with clear thinking, brand-new framework and clear objectives, and effectively learned the basic concepts, design ideas and curriculum objectives of the new curriculum standard. We have a deeper understanding of content standards and curriculum implementation suggestions. This semester, all grades have jumped to a new level under the guidance of the new curriculum standards. Second, classroom teaching, teacher-student interaction and common development. This semester, each of our math teachers is a practitioner of classroom teaching. In order to ensure the implementation of the new curriculum standards, we regard classroom teaching as a mathematics learning environment conducive to students' active exploration. The basic guiding ideology of teaching reform is to enable students to fully develop their emotions, attitudes and values while acquiring knowledge and skills. Mathematics teaching is regarded as a process of interaction and development between teachers and students. Organized the sixth class learning activity. Under the leadership of the teaching and research team leader, following the new curriculum standards, we will thoroughly understand the "independent-innovative" teaching mode in our school in a limited time. Actively use all kinds of teaching resources, creatively use teaching materials, teach in an open way, listen to comments repeatedly, and extract wonderful cases from research, teaching and listening to comments. The fifth-grade teaching and research group successfully demonstrated the lesson of circular decimal, which received good results and was affirmed by leaders and teachers. Practice shows that this cooperative lesson preparation method not only takes care of the actual situation of each class, but also helps teachers to complement each other, thus improving the overall lesson preparation level. It is the most valuable first-hand information for teachers to write lesson plans, review and reflect on their own personal experiences or omissions in teaching, and record the highlights or confusions of students' learning while still fresh in their memories after implementation. The accumulation of teaching experience and the absorption of lessons are very useful for improving classroom teaching and improving teachers' teaching evaluation in the future. What have you gained from these three years of reform? What's more, the preparation before class is not a mere formality, but a real study, and the collective wisdom of teachers has been fully exerted. After-class reflection has accumulated many useful experiences and inspirations for future teaching. 1 1 in the middle of the month, we held the sixth teaching festival, which lasted for one week. Seven teachers gave lectures on behalf of each group, and three classes were rated as excellent classes. This kind of open teaching is open, which breaks through the closed state of the original subject teaching. Put students in an open, active and diverse learning environment and learning situation. The design of "circle" in the sixth grade provides students with an opportunity to explore independently. Students can calculate the multiple relationship between circumference and diameter by measuring, forgiving and rolling, calculate the multiple relationship between circumference and diameter by counter, fill in the report, and observe the data to find the multiple relationship. From "yes-yes-always" to "always", it is concluded that the circumference of a circle is always more than three times its diameter. "Infiltrated a strong mathematical thinking method. In the process of observation, operation, discussion, communication, speculation, induction, analysis and arrangement, students have a good understanding of the formation, acquisition and application of the formula of circumference. Students are the main body of teaching activities, and teachers become teachers. The market for indoctrination has been greatly weakened. In the fourth grade, students find the position of the exchange factor and the law of constant product, then observe the numerical characteristics, change the order, add parentheses, and realize simple calculation. In design, no matter the problem, the existing data processing, the acquisition of mathematical conclusions and other links, all reflect the students' independent exploration and research, highlight the process and pay attention to the learning results. Pay more attention to the learning process and students' feelings and experiences in the learning process. The "practical problem" in the fifth grade is to study the movement of two objects. Teachers conduct, students perform, and design the distance from "distance-shortening-crossing-opposite". Change, feel the opposite motion, with the passage of time, the distance is gradually shortened, and the quantitative relationship between speed, time and distance in the opposite motion of two objects is obtained. A small performance is like eating a pot of eight-treasure vegetables with all kinds of nutrients. Students' wisdom, ability, emotion and belief are perfectly matched, their hearts are shocked, their psychology is satisfied, learning becomes their own master, their needs are discovered, learning is fun and learning is enjoyment. This shows that the process of designing students' active inquiry is a new space, carrier and way of inquiry learning. Generally speaking, this kind of teaching activity takes into account the harmony and unity of knowledge education and humanities education, and can not be completed overnight. It will be a long-term and valuable effort to improve every teacher's cultural level and life realm. Discussion and reflection extend the essence of open class to daily teaching practice. 165438 In the evaluation and acceptance of the fifth batch of "Pushing the Door to Teach Well" teachers held on June 30th, three teachers, namely, Liang Aiying, Huang Lina and Wang Guirong, were rated as excellent courses of "Multiplication and Simplification"; Tao Xingzhi's lecture on "Simplification of Multiplication" in Yangquan City was well received by the teachers who attended the seminar. On February 22nd, 2008, Wang Guirong's Understanding a Decimal was well received by the teachers and leaders who gave the lecture. In mid-February, four teachers participated in the learning and training of "Teaching and Love" in Shanxi Province, listened to the special lecture of famous teacher Yang and observed the demonstration teaching. Exploring the exquisite classroom teaching skills of famous teachers, teaching openly in the whole school, has been recognized by famous teachers and praised by teachers in class. 1 month 12, Wang Guirong went to Yuxian for class. Taking this as an opportunity, while summing up our achievements, we constantly reflect on teaching, promote curriculum reform through scientific research, seek development through innovation, and constantly extend the essence of open courses into daily teaching practice, so as to have an understanding of many problems that still plague us. Try to deal with the connection between mathematics teaching and real life, the importance of application consciousness and problem solving, pay attention to cultivating students' awareness and ability of applying mathematics, pay attention to cultivating students' awareness of inquiry and innovation, think often, study often and summarize often, promote curriculum reform with scientific research, seek development with innovation, further change educational concepts, adhere to "people-oriented, promote students' all-round development, lay a good foundation and cultivate students' innovative ability", and focus on research and application. Third, innovate evaluation to encourage and promote students' all-round development. We regard evaluation as a means to comprehensively examine students' learning situation, stimulate their enthusiasm for learning and promote their all-round development, and it is also a powerful means for teachers to reflect on and improve teaching. The evaluation of students' learning not only pays attention to students' understanding and mastery of knowledge and skills, but also pays attention to students' emotions and attitudes. We should not only pay attention to the results of students' mathematics learning, but also pay attention to their changes and development in the learning process. Grasping the mastery of basic knowledge, grasping the openness of classroom assignments, combining qualitative and quantitative methods, adopting a hierarchical system for quantitative purposes, and adopting the form of comments for qualitative purposes, paying more attention to what students have mastered, what progress they have made and what abilities they have. Such evaluation results are conducive to establishing students' self-confidence in learning mathematics and improving their interest in learning mathematics. In order to promote students' development, give an example of grade three comments: "We have learned a large length unit" Understanding of kilometers "these days. Through his own efforts, Shi can collect and record long distances and know how to guess and estimate long distances, which is the best in his class. However, there are some difficulties in language expression. I hope to continue my efforts. The score is excellent. " This kind of qualitative comment enables students to gain a successful experience, establish their self-confidence in learning mathematics well, and know where to continue their efforts. This semester, we have made some attempts in homework evaluation, which is a one-stop process of daily evaluation, weekly evaluation, monthly evaluation, teacher evaluation, student evaluation, group evaluation and parent evaluation. The teacher evaluates the day's homework, and the students register the evaluation results on the homework title page after self-examination. On Friday afternoon, the students graded it in groups and took it home. Sometimes I take my classmates' homework home. After parents evaluate, understand and compare their children's study and homework in the weekend, I put forward requirements for their children's study. Teacher Zhou Shi fully encouraged them to change stars. (Two A's 1 medal) Students set themselves a new learning goal every week, and turn this goal into daily learning behavior, so that they can learn experience day after day and week after week. The competition for stars is held at the end of the month. Students can taste the joy of their own success in learning within one month, and they can also learn from others. Every month is a new starting point, and all students stand on the same starting line. Students' learning distance is shortened, (9, 10, 1, 12,1). With the motivation of re-learning, the goal of learning has been set, which has played a good role in encouraging and evaluating. Fourth, grasp the routine to ensure the comprehensive completion of education and teaching tasks. Adhere to teaching as the center, strengthen management, further standardize teaching behavior, and strive to combine routine with innovation. Promote the formation of teachers' rigorous, solid, efficient and scientific good teaching style and students' earnest, diligent, realistic and knowledgeable good study style. The main forms of five-link evaluation are: 1, self-inspection-management, and strive to embody the people-oriented idea. Every teacher needs to check whether all his professional performances are standardized, appropriate and mutual-the team leader is responsible. Strengthen random teaching and research. 3. Inspection-random inspection: managers enter the classroom (notice lectures, push the door to attend lectures, follow lectures), attend lectures, read lesson plans, check homework, and check students' study habits, attitudes and effects. B Centralized inspection: conduct centralized spot checks on different grades and different routine projects every month. Adhere to the activities of a large teaching and research group once a month, correct omissions, and throw a brick to attract jade. Increase the transparency of examination, make routine work rigorous, meticulous and practical, and promote a virtuous circle of teaching management. All math teachers understand students' cognitive level from scratch, look for information, prepare lessons carefully, strive to create a relaxed and pleasant learning atmosphere, stimulate interest, teach students knowledge, and even teach them to seek knowledge, cooperate and compete, so as to cultivate students' correct learning attitude, good learning habits and methods and make them learn interestingly. Enriching the hierarchical design of homework, teaching methods, analysis of learning situation, and "win-win" communication are all topics of random teaching and research. New and old teachers learn from each other, promote each other, do a good job in routine work, do everything in teaching, do a good job in unit clearing and mid-term quality inspection, grasp the cycle of unit acceptance in class, and follow up with five good and poor students for inspection. In order to further implement the new curriculum standards, teachers are introduced into the new curriculum to attract jade. The teaching content, teaching methods, teaching evaluation and educational value of the new curriculum standard are embodied in four aspects: fraction and algebra, space and graphics, practice and synthesis, statistics and probability. It emphasizes students' mathematical activities, develops students' sense of number, spatial concept, application consciousness and reasoning ability, optimizes the design of written test questions, designs test questions during the formation of knowledge and skills, designs developmental test questions and designs life-oriented mathematics test questions. The mid-term quality inspection was conducted on June 5438+065438+1October 12, with the participation of all students. The pass rate is 97% and the excellent rate is 78%. Examination is really used as a means to promote students' all-round development and improve teachers' teaching level. Five students before and after class were followed up, and the examination papers were carefully analyzed, and the situation of each student was analyzed, so as to find a breakthrough point for future teaching. At the same time, we have made overall arrangements for students' one-day activities at school. Extracurricular interest activities are organized and planned, and time, content, teachers and venues are all implemented. The organization report in the middle of each interest activity shows that students not only consolidate and apply what they have learned in various interest activities, but also build a new knowledge structure for the future, improve their practice and application ability, and have. Really, the first class lays the foundation, and the second class develops its specialty. No pains, no gains, and teaching is accompanied by bitterness and joy. We will, as always, make persistent efforts and do a better job in line with the principle of "study hard, think hard and work hard".
