Ouyang Yan:
This is a refreshing lesson, a good lesson that highlights teaching and learning with a brand-new educational concept. First, teachers skillfully create lively and interesting hoop games for students as teaching situations, and integrate mathematics knowledge into activities that students are interested in, so that students can learn mathematics in games and run through the whole classroom. This has built a learning bridge for students and laid a foundation for the smooth progress of teaching activities. Therefore, students learn easily, happily and actively.
Secondly, the introduction of competition mechanism into the classroom stimulates students' curiosity and competitiveness, and cultivates students' team spirit and sense of competition.
Third, paying attention to the process of students acquiring knowledge is another highlight of this class. For example, when summing up the method of continuous addition, the teacher did not teach the students, but the students explored it independently. Teachers just make the finishing point to guide them, and teachers and students jointly sum up three vertical writing methods of continuous addition. It has well cultivated students' awareness and ability to actively explore new knowledge.
Fourthly, properly cultivate students' estimation consciousness.
Fifth, students' ability to solve problems has been well cultivated. For example, in the last exercise, the teacher only gave the price of three toys and 600 yuan money, allowing students to ask questions and solve problems by themselves, so that students' intelligence can be developed, their ability can be cultivated and their quality can be improved. At the same time, it also cultivates students' ability to use mathematical knowledge to solve practical problems in life, so that students can fully feel that mathematical knowledge is around us and is often encountered and used in daily life.
Of course, this class also has some shortcomings:
First, it is not enough to cultivate students' divergent thinking in the process of learning. For example, in the first round of competition, students should be allowed to fully express their views, because the teacher did not emphasize the need to judge the outcome by the total number of rings at the beginning. Therefore, in terms of the number of times, it makes sense for boys to win and lose. Teachers should not only give affirmation, but also seize this opportunity to let students find a judgment standard, which is more natural and conducive to the development of students' thinking.
Secondly, in the second round of hoop competition, when the boys' hoop scores are obviously lower than those of girls, if the teacher can ask a question in this place: "Is it possible for boys to win?" This will be the icing on the cake.
Third, the process of students' "speaking" is not reflected enough. When a teacher asks a question, he is often satisfied with one or two students' answers, without taking into account a large number of students.
Peng Xianghui:
1. Teachers pay attention to teaching students thinking methods and cultivating students' thinking ability. In the whole class, teachers are good at inspiring students to explore their ideas from many angles and aspects, encouraging them to speak out their different views boldly, and giving affirmation or encouragement in time. However, while encouraging students to diversify their ideas and algorithms, they also don't forget to teach students general optimization calculation methods, so that their divergent thinking and convergent thinking have been * * *.
2. Teachers make students truly become the main body of learning. In the whole teaching process, teachers hardly make any conclusions instead of students. Teachers always guide students to find problems, and then guide students to find ways to solve problems and gain learning experience.
3. Teachers boldly break through the original framework of textbooks, flexibly use textbooks, and run hoop games through the whole classroom teaching. The designed activities and competitions are extremely open, which makes the students' personality get publicity.
4. It has greatly stimulated students' interest in learning. First of all, this class introduces new lessons with the game of rolling hoop, and runs through the whole classroom teaching, so that students can play and learn from middle school. It is also because teachers have created a kind, equal and democratic learning atmosphere, so that students can naturally integrate into the classroom and their enthusiasm is always high.
5. Mathematics comes from life and serves life. The application expansion topic designed at the end of this lesson is to let students use what they have learned to solve problems in life and really practice the basic idea that everyone learns useful mathematics in the new curriculum.
Disadvantages: the teacher erased the first student's blackboard in a link, which was a small blow to that student; The forms of teaching can also be diversified, such as designing students to adjust the classroom in the form of group cooperation and communication; Teachers' ability to control the classroom needs to be strengthened. In the classroom, some students are answering the teacher's questions, but some children are playing with things, which shows that some students are not motivated.
Liu Xiaofeng:
Generally speaking, I think this is a successful lesson, which has the following characteristics:
1, teachers can creatively use teaching materials, optimize the content, and use children's favorite ring games to run through continuous mathematics knowledge, which conforms to the psychological characteristics of junior two students, makes the classroom atmosphere good, and teachers' thoughts have advanced consciousness.
2. Creating a relaxed teaching atmosphere and promoting teaching democracy. In this class, the teachers fully grasped the students' fun and playful nature, and imparted knowledge to them in the form of games. Coupled with friendly language and decent teaching style, the whole classroom is vivid and orderly.
3. It embodies the diversity of algorithms, highlights the calculation and highlights the students' oral expression ability. Teacher Tan not only teaches students the method of continuous addition, but also pays attention to students' oral expression ability, so that students can make sense clearly.
4. Highlight the new educational concept of letting students solve problems. In the practice session of this class, the teacher created a teaching situation of "I compete with Tintin". Let students know through the competition that it is not necessary to calculate the total score to judge whether the score exceeds Tintin, thus cultivating students' problem-solving ability. comment
Step 4 close
Connecting with life and strengthening application consciousness. Practice has a certain density, which embodies the idea of not capping and not guaranteeing the bottom. Some suggestions: the same student answers too often and other children have too few opportunities to speak. Secondly, the form of consolidation exercises is mainly watching screen exercises, and students write fewer exercises. It is not enough to combine multiple senses with words, hands and brains. In addition, the extension of the class can be designed more exquisitely.
