Advantages:

1, the introduction is novel. The teacher leads the students to recall the formula and skills of fractional multiplication they have learned before, and then naturally introduces the concept and calculation method of fractional division by integer. This kind of introduction can stimulate students' interest and curiosity in learning and make them participate in the classroom more actively.

2. The explanation is clear. The teacher explained the concept and calculation method of fractional division by integer in detail, and gave clear examples and explanations. This way of explanation can help students understand concepts and calculation methods in depth and improve the learning effect.

3. Practice fully. Teachers consolidate what they have learned by letting students do a lot of exercises, and give timely feedback and guidance. This kind of exercise can help students master the calculation method of divisible fractions and improve their calculation ability and problem-solving ability.

Disadvantages:

1, the explanation speed is slightly faster. Because the content of this lesson is more important, the teacher may be eager to complete the teaching task and explain it too fast, which leads to some students unable to keep up with the teacher's rhythm and understand the content of the explanation. It is suggested that teachers adjust the speed of explanation appropriately to adapt to the learning ability and level of most students.

2. Insufficient classroom interaction. Although the teacher asked the students to have some group discussions and questions, the whole class was mainly explained by the teacher, and the interaction between the students was not sufficient. It is suggested that teachers should add some links of students' independent inquiry and cooperative learning, and encourage students to actively participate in classroom discussions and exchanges.

Suggestion:

1, adjust the interpretation speed. Teachers can adjust the explanation speed according to students' feedback and learning situation to ensure that most students can keep up with the teacher's rhythm and understand the explanation content.

2. Strengthen classroom interaction. Teachers can add some links such as group discussion and independent inquiry, encourage students to actively participate in classroom discussion and exchange, and improve students' classroom participation and learning effect.

Significance and application of integer fractional division;

1, a fraction divided by an integer can represent the relationship between a part and the whole. When we want to calculate a part of the quantity of an item, we can divide the fraction by the integer. For example, if we have three apples and each apple is divided into four parts equally, then 1/4 of one apple is 1/4 of three apples. Dividing a fraction by an integer can express the relationship between this part and the whole, which is very useful in mathematics and real life.

2. Fractions divided by integers can be used to simplify fractions. In mathematics, the simplification of fractions is very important. By dividing a fraction by an integer, we can turn the fraction into the simplest form, which helps us to better understand the nature and calculation method of the fraction. For example, we can convert 3/4 into 6/8, and then simplify it to 3/8, so that we can express the value of the score more clearly.

3. Fractions divisible by integers can be used to solve practical problems. In real life, it is often necessary to divide an article into several equal parts. For example, if we need to divide a cake into 8 equal parts, then each part is 1/8. By dividing the fraction by an integer, we can easily calculate the number of each copy. In addition, in business, engineering and other fields, the method of dividing fractions by integers is often used to solve practical problems.
