Force, make it understand the benefits of mathematical processing, cultivate students' attitude of consciously using mathematics in daily life, so as to achieve
The goal of mathematics teaching in Japanese primary schools.
For example, in the last semester of the third grade, when the measurement units of learning volume and length were km and m respectively, such a problem appeared. (The following is
Schematic diagram)
(attached {Figure})
Refer to the above figure and find the following length:
The content of the new lesson is:
1. The distance from the school to the bookstore is 750 meters. How far is it from the school to the library?
1 km =1000m.
2. What is the distance from the school to the station, km and m?
These exercises are:
(1) Please find out the distance from the school 1km.
(2) How many kilometers is 2000 m? How many kilometers and meters is 2600m?
(3) What is 5 km? What is 5km70m?
(4) As shown in the picture, how many different routes are there from Xiaohong's home to school?
(1) If you pass the bank, how many kilometers and meters do you have to walk?
If I go through the city hall, how many kilometers and meters must I walk?
② Compare the distance and distance between Xiaohong's home and school.
From this teaching content, we can realize the significance of open questions. Through teaching, students not only learn the length
Unit and conversion relationship, and learned to use mathematical methods to solve practical problems around students. At the same time, let students feel learning.
The importance and necessity of learning mathematics knowledge. Not only let students learn mathematics knowledge, but also cultivate them to use mathematics knowledge.
Attitude towards daily life. After class, students can draw a road map to school according to their actual situation. This not only consolidates
The length of unit knowledge also cultivates students' ability to think in an orderly way in daily life. "Dead" what you have learned.
Knowledge has become a "living" content closely related to every student's life.
This is another example.
This problem is a problem in the textbook of the second semester of grade three in primary school. The title is "Visiting the Aquarium". (The sketch is shown below)
Number of people going
Adult children male 0.5 female 1 3 tram fare car fare ticket price adult 180 yuan adult 220 yuan adult.
150 yuan children, 90 yuan children 1 10 yuan children, 50 yuan.
(attached {Figure})
In Qiu Zi, they gathered at school, went to Dongshan Station to take a tram to the aquarium, and then took a bus back to school after the visit.
1.( 1) They started from school at 8: 25 and asked for the next time and time.
① Time to Dongshan Station;
② Waiting time at the station;
(3) Time by tram.
(2) It takes 20 minutes to get to school by bus from the aquarium. If you get on the bus at 1 1:30, what time will you arrive at school?
If you take the bus 1 1:45, what time will you arrive at school?
(3) Which is the longer round trip, and how many m?
(4) If you go to eight children together, how much does it cost to have a child?
2. Try to change the number of people and the price, and write various types of questions. And then solve these problems.
It is not difficult to see that this teaching content is comprehensive, including many aspects of knowledge, such as length, time,
Currency, etc. The requirements for teachers are very high. At the same time, because this problem comes from life, students feel very cordial, so again.
I can't feel its difficulty. So teachers and students can solve many problems in a very relaxed and happy atmosphere.
From the above two examples, we can easily realize that the teaching of open application problems is very important for cultivating students' understanding of daily affairs.
The ability to think methodically and understand the use of mathematics is very important. At the same time, it is very important for teachers to deal with such problems.
More demanding. Teachers should not only tell a concrete example, but also face many problems of different types and contents at the same time.
Give an explanation. In mathematics teaching, it is not easy for teachers to take care of students' enthusiasm and grasp knowledge points.
Well done.
In a word, Japanese elementary school mathematics education circles pay more attention to the teaching of solving applied problems and their thinking methods, and are paying attention to the methods of dealing with applied problems.
There are many ways in the world that are completely different from ours. These inspired us:
1. Open the teaching of applied problems and attach importance to the teaching process, so that students can not only master some knowledge of mathematics through learning.
Knowledge also makes students realize the significance of learning mathematics and the benefits of mathematical processing.
We have made great progress in this respect, but at present, the content of mathematics teaching in our primary school is too far away from students, and students are
Solve problems while solving problems, and you don't feel deeply about the necessity of learning mathematics knowledge, which is easy to produce weariness.
2. Open application problem teaching can activate students' thinking and improve their analytical ability in the process of solving problems.
Ability.
At present, there is a problem of demanding too much from students in the teaching of applied problems. Although we have begun to pay attention to this problem.
For example, students are asked to rewrite conditions or ask questions. But it still looks rigid. Because students can only follow a certain box.
The box to rewrite. Japan's open questions give us great inspiration: let students find their own conditions and solve their own problems.
Problems, without any framework, can write many application problems, which provides conditions for students to continuously improve their ability to analyze problems.
Although there are many advantages in the application teaching of open questions, we should also pay attention to moderation, and only in this way can we give full play to our advantages.
