First, the draft, classroom exercises "out of control"
Students with high consciousness and good habits can carefully draft and complete classroom exercises, while students with low self-discipline ability scribble on the draft books one by one, and low-level mistakes such as digital dislocation and decimal point dislocation often appear in calculation. Some students even think they understand, and simply don't do classroom exercises. In addition, teachers can't read and correct drafts and classroom workbooks in time, and teachers can't find mistakes in students' classroom exercises in time.
Second, the classroom homework into homework
In teaching, many teachers are used to assigning homework after new teaching AIDS, which often leads to the phenomenon that students can't finish after class, which provides convenience for a few students to copy homework. This kind of homework not only can't really reflect students' learning level, but also takes up their precious spare time, which is not good for their physical and mental health.
In view of the above situation, students' exercise books are redesigned in mathematics classroom teaching, and the students' draft books, classroom exercise books and classroom exercise books are designed as follows: the left side is the practice area, and the right side is the draft area. In teaching, review questions, classroom exercises and classroom assignments are arranged in the exercise area of the exercise book, and exercises correspond to drafts one by one. In teaching practice, the author found that this method has the following advantages:
1. Promote the formation of students' good study habits. Because teachers have to check exercises and drafts in class, students pay attention to the writing quality of drafts, and the accuracy of calculation is obviously improved. At the same time, the whole calculation process provides convenience for students to check and check.
2. It is convenient for teachers to evaluate correctly and teach students in accordance with their aptitude. If teachers find mistakes in correcting students' homework, they will find the reasons by reading the manuscript, so that teachers can explain and correct the learning weaknesses of individual students in time and teach students in accordance with their aptitude; Some questions, the students' results are correct, but the teacher looked at the students' drafts and found that the students' thinking and calculation process were wrong. At this point, the draft can provide a basis for teachers' correct evaluation, and effectively prevent students from attaching importance to results over process and copying homework from each other.
3. It is conducive to the establishment of students' self-confidence and the cultivation of innovative consciousness. Some students are timid and lack confidence. Although some topics have good ideas, they dare not raise their hands to speak in class. Using this method is very helpful for teachers to observe and master the learning situation of such students. For example, in Book 11 of Mathematics in September 1st Primary School, Example 2 "A number divided by a fraction", how many kilometers does a car drive per hour 1 8km,1hour? In teaching, the author asks students to read questions, analyze the quantitative relationship of questions and try to make them. According to the quantitative relationship of "distance ÷ time = speed", many students have a formula of 18÷. When correcting students' homework, it is found that the formula of one student is different from that of other students, that is, the multiple of 18×( 1 \ times 18 is the vehicle speed, and (1÷ is actually the reciprocal of the solution, from which18 ÷ is deduced. This practice is convenient for teachers to find the bright spots in students' thinking process, and at the same time, it also establishes students' self-confidence and cultivates students' innovative consciousness.
Some teachers may ask, will the students' draft book, classroom exercise book and classroom exercise book be combined into one, and the exercise books will be in a mess? Will it affect the progress of classroom teaching if students carefully draft and finish classroom exercises? Practice has proved that:
Students regard drafts and classroom exercises as part of classroom assignments, and their writing is very standardized and neat. Because students pay attention to the quality of writing, it will affect the progress of classroom teaching at first, but after a period of training, the speed will naturally catch up. In order to improve the speed of students' homework, the author suggests adopting the method of dispersing homework and evaluating classes in time in teaching. According to the progress of classroom teaching, after the teaching of a knowledge point, exercises will be arranged and consolidated in time. When the classroom teaching ends, the practice will also end. When students practice, please give students timely feedback and praise and encourage the correct performance immediately, which not only mobilizes students' enthusiasm, but also helps other students to find out the reasons for their mistakes in practice through comparison and correct them in time, thus promoting the understanding of new knowledge and laying a good foundation for the later teaching. At the same time, this practice is also conducive to improving the speed of students' homework and ensuring that students' homework is completed in class.
Practice is the only criterion for testing truth. In my teaching, I optimized and merged the students' draft book, classroom exercise book and classroom exercise book, and found that this practice is really practical for students' learning and teachers' teaching.
