"Mathematics Curriculum Standard" clearly points out: "Students' mathematics learning content should be realistic, meaningful and challenging, and should be conducive to active observation, experiment, speculation and communication. Content should be presented in different ways to meet diverse learning needs.
As an effective mathematics learning activity, students' hands-on practice, independent exploration and cooperative communication are important ways for students to learn mathematics. Based on this teaching philosophy, Mr. Tang and Mr. Zhou are striving to create a multi-level, three-dimensional, interactive and harmonious life classroom that integrates cognition, life, emotion and personality.
Looking at the teaching and learning of the whole class, I think the following points have achieved the expected results:
First of all, experience the process of abstracting percentage from the actual situation and realize the necessity and significance of introducing percentage.
The meaning of number is the core goal of learning number, and the focus of this lesson is to let students understand the meaning of percentage. This includes not only what percentage is, but also why people introduce percentage, that is, the necessity of introducing percentage, where people use percentage, that is, the scope of application of percentage, and the relationship between percentage and score, that is, the connection between the two.
This lesson allows students to experience the process of abstracting percentage from specific situations in situations that students are interested in, which not only helps students understand the meaning of percentage, but also cultivates their ability to solve practical problems.
Secondly, the practical design of the classroom is set up, which is diverse and in-depth, challenging and innovative.
For example, Mr. Zhou asked students to communicate the meaning expressed by the collected percentage, and then consciously supplement and expand it on the basis of students' full communication. It seems casual, but it is unique. This is not only a simple repetition of the percentage collected with students, but also a blank collected by students, and students are also educated on the environment. Their presentation makes students' cognitive structure more perfect.
In addition, exercises such as "writing percentages, distinguishing between true and false, and guessing percentages by reading idioms" have sublimated students' understanding of percentages and made this class wonderful and efficient.
In particular, the idiom "Percent Guess" gives people a refreshing feeling, which integrates mathematics with profound Chinese subjects, embodies the origin and connection between mathematics and China culture, and practices new ideas well.
The curriculum emphasizes the comprehensive concept of primary school curriculum. In this implementation process, students' enthusiasm is improved, the atmosphere is active, and good results have been achieved.
Third, cleverly set the end of class, thinking unfinished.
Good classes should also set words. This will easily arouse students' thirst for knowledge and make full psychological preparation for the next class.
In the conclusion, Edison's famous saying: "Genius = 99% sweat+1% inspiration" seems to be a casual example, but in fact it is original, which is not only the infiltration of culture, but also the concentrated expression of educational consciousness, and has become the crowning touch of this class!
Fourth, teachers' language is concise and create a relaxed learning atmosphere.
The teacher's language is concise and neat, and he gives timely and appropriate comments on the students' speeches, such as "Give him applause" and "He speaks really well".
Better control the classroom atmosphere and create a relaxed learning atmosphere for students. At the same time, give students a chance to experience happiness. Let students enter the next step of study with pride of success and more passion.
