First of all, students should know that they should identify the main characteristics of the observed object purposefully and pay attention to discovering the conditions and reasons that cause the change.
Secondly, it is necessary for students to understand that observation requires a certain effort to overcome certain difficulties in order to find problems, correctly understand things and draw correct conclusions.
(1) Cultivate students' observation ability in demonstration experiments.
There are many demonstration experiments in the learning process, and students are very interested in demonstration experiments, but they often fail to grasp the key points in observation, which requires teachers to guide students to observe demonstration experiments in actual teaching, which is very important to cultivate students' observation ability.
(2) Cultivating students' experimental quality in group experiments.
(3) Carry out extracurricular activities to stimulate students' interest in observation.
(4) As far as possible, make use of multimedia teaching methods to assist teaching, so as to improve students' observation interest and ability.
The introduction of computer multimedia into junior high school physics teaching, as a new teaching method, has changed the rigid teaching method in the past. Illustrated and colorful, it strengthens the performance effect, improves students' interest and enthusiasm in learning, cultivates students' observation ability and helps students understand knowledge.
2. Instruct students to do more experiments.
(1) Understand physical experiments and their functions.
Physics is a science based on observation and experiment. Many people's physical knowledge is summed up through observation and experiment. Junior high school students have incorrect ideas about why to do physics experiments, some are indifferent, some are eager for teachers to do more experiments, but in fact they don't know why to do physics experiments. Through experiments, we can have a concrete and clear understanding of physical facts, which is helpful to understand physical concepts and laws.
(2) urge students to do experiments seriously.
① Instructing students to do experiments with textbooks in the early stage of junior high school physics experiments, and instructing students to do experiments arranged in textbooks are conducive to cultivating students' good habits of using textbooks correctly and developing good quality of respecting science.
(2) Create opportunities to do more experiments and form a good habit of diligent hands-on.
The cultivation of students' experimental ability is a long-term work, which should run through the whole physics teaching process and involve students as much as possible. In the classroom demonstration experiment, we should also try to create opportunities for students to do it.
③ Do the experiment well with simple equipment.
Sometimes many physical experiments can be completed with simple equipment.
Second, good "questioning" is a bridge for quality education.
1, being good at asking questions is the premise of innovation.
Students' understanding of the problem is not satisfactory and should be paid enough attention to. Students are often guided to review the achievements in the history of science because they are good at finding problems. Educate students to be good at finding problems and make them realize that finding problems is also learning, and it is a deeper learning.
2. Guide students to be good at designing problems.
In junior high school physics teaching, teachers should be good at designing questions and guiding students to learn new knowledge. The design questions should be artistic, and different questions should be designed at different stages according to the teaching content.
3. Guide students to be good at asking questions.
Students are often inspired to ask questions in various ways and lead them to discuss why they studied physics in the first place. Further guide students to ask questions from reading texts, and ask questions in social practice activities, so that students can ask questions found in time and explore them.
Third, practical innovation is the destination of quality education.
1. Cultivate students' ability to solve problems by applying physical knowledge.
After students understand the importance of physics experiments, they will actively do experiments well. When students can basically complete the experiment, teachers should put forward higher requirements for students' experiments, such as guiding students to do some verification and design experiments.
2. Guide students to learn new knowledge.
Mastering what you have learned is to learn new knowledge better. When students learn something, they should take the initiative to learn new knowledge.
3. Apply physical knowledge to solve practical problems.
