Junior high school students who want to improve their academic performance need to do the following:

1. Take classes seriously: The learning efficiency in the classroom determines the academic performance of junior high school students to a large extent. High and low, the second grade of junior high school is a learning stage that connects the previous and the next, so junior high school students must pay attention to the learning efficiency in the classroom when studying at this stage.

2. After-school exercises: It is necessary for junior high school students to do more after-school exercises. This is not only completing the homework assigned by the teacher, but also a process of consolidating and reviewing the knowledge learned. Since the learning tasks for the second grade of junior high school are very large, doing the questions is an essential process. At the same time, junior high school students should complete their homework as early as possible so as not to affect their sleep time.

3. Ask for advice in a timely manner: This is something that many junior high school students cannot do, because many junior high school students think that asking teachers or classmates for advice is a very shameful thing, which is wrong. The teacher's job is to impart knowledge to the students. If all the junior high school students understand the knowledge taught by the teacher, then the students do not need to ask for advice.

In the final analysis: junior high school students do not ask the teacher for advice because of vanity. As long as junior high school students abandon this vanity. When you encounter a problem that you don't know, you can ask the teacher for help in time. Then the academic performance of junior high school students will definitely improve.

1. Developing good eating habits can improve academic performance.

A new study points out that children with healthy eating habits perform better in school and have higher grades. The researchers recorded the children's diet, height and weight, and used the International Diet Quality Index system to evaluate the children's overall dietary quality. The higher the index, the higher the quality of the diet. Among them, adverse health factors include saturated fat and salt; healthy foods include various fruits and vegetables, cereals, dietary fiber, protein, calcium and moderate fat intake.

The researchers also conducted standard literacy tests on the children and analyzed the relationship between eating habits and learning ability. It was found that when children's diets included more fruits and vegetables and less fat, they were significantly less likely to fail literacy tests. Relative to children with the lowest dietary index, children with the highest dietary index were 41% less likely to fail to meet the target.

2. A reasonable diet not only allows children to eat healthier, but also affects their academic performance.

Ge Zhengming, a researcher at the China Family Education Research Association, said that nutritional adjustments are related to children’s physical and intellectual development. Stable blood sugar can improve children’s memory by 5% to 15%; the acid-base balance of blood in the human body, It can greatly improve children's memory and thinking ability; eating less fried and other junk food can reduce children's precocious puberty, malnutrition, obesity, poor memory, etc.; strengthening breakfast and aerobic exercise can promote children's efficient learning, etc.
