First, sincere evaluation-highlighting the advantages of students
In the process of primary school mathematics teaching, teachers should carefully observe students' learning and activity performance and give corresponding evaluation, so that students can feel the joy of success in the evaluation language affirmed and encouraged by teachers. Teacher's body language is the best way to evaluate, such as eyes, expressions, limbs and so on. With the gradual deepening of teaching content, teachers' kind and natural eyes have a good role in promoting classroom teaching. A look of approval or trust, gentle gesture and peaceful language will inspire students to make self-correction, thus improving their confidence in learning. More importantly, teachers should grasp the starting point of evaluation and give students timely evaluation in vivid language, such as "your way of thinking is different from others, which is novel", "your way of thinking in solving problems is ingenious" and "it is great for teachers to see you actively answer questions". Through such evaluative language, students are encouraged to explore knowledge and answer questions actively.
Second, the transposition of evaluation-to stimulate the subjective consciousness
Incentive evaluation needs to regard each student as the main body of learning, satisfy students' emotional needs through diversified evaluation, and urge students to actively participate in mathematics learning, thus improving students' efficiency in learning mathematics. In the process of primary school mathematics teaching, teachers should evaluate students differently, care about and respect students' subjective consciousness, and promote their all-round development. Teachers can encourage students to evaluate themselves and each other and pay attention to positive guidance, so that students can not only realize their own advantages and disadvantages, but also be good at finding out what is worth learning from other people's viewpoints. Through diversified teaching activities and timely and appropriate incentive evaluation, we can protect students' learning enthusiasm and promote them to actively explore mathematics knowledge.
For example, when teaching the first volume of fifth-grade mathematics, the teacher can show two identical right-angled trapezoid figures, the upper bottom is 25cm, the lower bottom is 15cm, and the height is 10cm, so that students can calculate them in different ways: ① (25+ 15) × 10. ②(25+ 15)× 10÷2×2。 Method (1), most students say it doesn't work, and a few people are thinking or agreeing that it is right; The students think that method (2) is correct. Faced with this situation, students are eager for the teacher to make a statement. At this time, teachers can ask the students calculated by methods (1) and (2) to defend themselves and argue with each other, thus prompting students to realize active knowledge generation through self-analysis and comparison.
Third, positive evaluation-explore students' bright spots.
Incentive evaluation is an important means to motivate education, which can promote students' continuous progress. Incentive evaluation can effectively evaluate the results of primary school students' mathematics learning. Reasonable application of incentive evaluation in primary school mathematics teaching can not only improve students' learning enthusiasm, but also improve teaching efficiency and quality. When implementing incentive evaluation in primary school mathematics teaching, we need to pay attention to the enlightening application of incentive evaluation in primary school students' thinking and learning. The teacher's simple words play an important role in students' minds. Once the teacher's evaluation stimulates students' singing, it can stimulate students' learning motivation, activate students' thinking and make them invest in mathematics teaching. Therefore, teachers should pay attention to the enlightening and guiding effective application of evaluation when evaluating mathematics teaching in primary schools.
For example, when teaching "Axisymmetric Graphics", the second volume of fifth grade mathematics published by People's Education Press, teachers can show five kinds of graphics, such as circle, parallelogram, trapezoid, regular pentagon and triangle, so that students can judge whether there are axisymmetric graphics in these graphics. If students only make guesses based on experience, teachers should tell them appropriately: "Don't trust your eyes too much, but take practice as the standard. Let's start folding to see which are axisymmetric figures and which are not? " When students focus on the judgment of axisymmetric graphics, let them fold with the teacher's demonstration and find out the answer. This not only deepens students' impression of learning axisymmetric graphics, but also enhances students' practical ability, so that they gain motivation and confidence in learning mathematics, and then gradually succeed.
Fourth, diversified evaluation-promoting all-round improvement.
When applying incentive evaluation in primary school mathematics teaching, we should pay attention to the rationality of language use. Reasonable language expression can more effectively realize the teaching application value of incentive evaluation, and promote and guide students to improve their enthusiasm and enthusiasm for learning mathematics. Because students' own thinking and knowledge levels are different, their thinking angles are also different. When teachers evaluate students, the evaluation language should be multi-angle and multi-level, not limited to simple motivational language such as "you are a genius, you are great". Teachers' evaluation language should be able to penetrate into the learning methods of cultivating primary school students' study habits and promote the overall improvement of students' comprehensive quality.
To sum up, incentive evaluation is an effective means to stimulate students' learning motivation and promote emotional communication between teachers and students. In the process of primary school mathematics teaching, teachers should strengthen students' target behavior through encouraging evaluation and adopt diversified evaluation methods and means to better motivate students and promote their all-round development.
