1 How to improve the quality of junior high school math homework
First, let students understand the importance of practice.
American writer Annette? Brushaw wrote "10 1 Suggestions for Teachers". In the chapter of course guidance, 32 articles say "Don't just talk and don't practice". Learning is a repetitive process, especially science learning. If you just attend class and don't finish your homework carefully, it's just an armchair strategist and meaningless. Annette? Brushoff said in 32 "Don't just talk and don't practice": "We can't learn to swim just by listening to swimming lessons; Only by swimming in the water can you learn. You can't learn to drive just by listening to driving lessons; Only when you start can you start. This is true in life and in class. " The process of feedback correction in mathematics is an important method to ensure that most students give full play to their basic cognitive characteristics. At the same time, practice can make students feel more deeply what problems still exist in their knowledge and answer them better. The Importance of Math Practice Annette? Bradshaw used China proverbs to illustrate this point. He wrote, "I heard of it, and then I forgot; I saw it, so I remembered it; I did it before I knew the truth. " He said in a student's tone: "Say, say, teach, teach, if you keep your mouth shut, I will learn more;" Please stop talking and let me do it myself! "
Second, the standardization of operation.
Teachers should give students a standard blackboard writing in class, which is exemplary. Without rules, there would be no Fiona Fang. Therefore, our teacher should tell students clearly what is normative and what is not. For example, it is not allowed to write "solution: original formula =" in calculation problems. In solving application problems, there must be "solution: design, column, test and answer", and fractional equations must have "root test". These are the work norms that students must have to cultivate good study habits and rigorous thinking.
Third, the timing of operation and quantification
Math homework requires students to finish it regularly and quantitatively every day, that is, to finish a certain amount of homework within a certain period of time, preferably for 20-30 minutes. This method is particularly effective for mathematics subjects, because the knowledge points of mathematics are clear every day. Completing homework regularly and quantitatively can not only improve students' problem-solving speed, but also allow students to plan their time as a whole. I'm practicing here, and I suggest you do "classroom exercises", that is, arrange some homework or exercises organically in the teaching process, which not only strengthens classroom training, but also reduces the heavy homework burden of students. At the same time, practicing in class is conducive to guiding students in different categories. When students work independently, teachers can focus on helping students with poor learning ability to improve their ability to analyze problems. Students with strong learning ability can choose some difficult and representative comprehensive problems to do according to their actual knowledge level, which not only ensures the requirements of the syllabus to be realized, but also satisfies the thirst for knowledge of outstanding students and achieves the effect of teaching students in accordance with their aptitude.
2 Help students understand the meaning of the question
First-year students come from different kindergartens and their learning foundations are uneven. Some students may already know hundreds of words, while most students only know very simple Chinese characters such as "one, two, three, big and small". How can you understand a topic with a large number of words at this level?
An assignment in the first volume of senior one, the content is very simple, but there are many words. This is tantamount to reading a gobbledygook for freshmen? Many parents in the class complained to me when they came to the school to learn about their children's learning: "The children could actually do the math knowledge in the exercise book, but they made mistakes because they didn't understand the meaning of the topic." Indeed, it is for this reason that most first-year students make mistakes when doing their homework. Therefore, when guiding students' homework, teachers should first help students understand the meaning of the problem, what the problem is for and how to do it. In this way, students' homework will not be "impossible to start", let alone "random to start". So how to help first-year students understand the meaning of the question?
First, memorize commonly used Chinese characters in class. Teachers collect some words that often appear in homework, such as: "A * * * has, from left to right, from right to left, count, longest, shortest, lightest and heaviest", and make them into new word cards or write them on the corner of the blackboard, so that students can often identify them in class or in the morning reading. Over time, students will recognize these words when they see them.
Second, cooperation in Chinese classes. In the limited teaching time, teachers should not only spend a few minutes to guide students to understand the topic, but also teach students to write some Chinese characters, such as: Unit 2, Book 1, Grade 1, requiring students to write Chinese characters such as "many, few, long, short, light and heavy" in many places of homework; Unit 8 "Know the Clock" requires you to write "Time and Half", but most of these new words only need to be recognized in Chinese. Faced with this situation, we might as well find out these words in advance, so that Chinese teachers can tell students how to write in advance when teaching in class, so that they can learn to write.
3 methods to improve the effectiveness of junior high school math homework
Carefully Designing Homework —— Improving the Effectiveness of Math Homework
Variable-law practice design is to use variables to practice design in mathematics teaching, select appropriate questions, change conditions and conclusions, get new questions, change from one question to multiple questions, guide students to deepen problems step by step, overcome mindset, broaden their thinking, cultivate divergent thinking ability, and improve students' agility in thinking and flexibility in solving problems.
Trap intensive practice design some mathematical knowledge. It is impossible for teachers to deepen students' impression and thorough understanding only by following the book or explaining it in class. At this time, if teachers skillfully design "traps", they will consciously make students suffer "setbacks", forcing them to find the crux of their mistakes and preventive methods, thus leaving an indelible mark after learning, effectively cultivating the rigor of students' thinking, so that they will not take detours or take fewer detours when solving problems in the future.
Grouping problems-similar problem design, inductive classification and grouping problem teaching can help students deepen their understanding of knowledge and cultivate their ability to draw inferences from others. Through limited practice, they can realize the same law of solving problems and get rid of the ocean of problems. There are many forms of problem sets, including overlapping problem sets, series problem sets, parallel problem sets, similar problem sets, variant problem sets and thematic problem sets, among which "similar problem sets" are the most meaningful. Its main advantages are: broad thinking, clustering problem-solving methods and strong thinking regularity, which not only helps to improve students' problem-solving ability, but also helps to cultivate students' abilities of analogy, induction, guessing and exploration.
Perfecting the evaluation system-improving the effectiveness of mathematics homework
It has great limitations to make the symbols of homework correction clearer. Traditional homework correction only uses "×" and "√". We consider studying and designing a new symbol system of evaluation and error correction in teaching practice, so that students can clearly see where and what kind of mistakes they belong to; Which homework is excellent and creative; Have you been praised for your homework, and so on. This is more conducive to the feedback of evaluation and helps to promote the development of students.
Combining the grade system with the hundred-point system, every student wants to get good grades in his homework and get excellent grades, but it is very difficult for students with learning difficulties. In order to meet the needs of all students, we assume that the grading system (excellent, good, etc.) should be organically combined with the 100 scoring system in homework evaluation. The grading system is used to distinguish the cleanliness of homework, so that students can give satisfactory returns as long as they work hard, thus improving their interest in homework and developing good writing habits. It also shows the correct degree of homework with a percentage system, which improves students' competitive consciousness and mobilizes students' learning enthusiasm. The close combination of the two should benefit students a lot.
