How to carry out experimental innovation in science teaching

More hands-on operation, so that students know how to apply more! Innovation is not a change of teaching, good teaching is to let students feel the existence of what they are learning and its application in society!

The new teaching equipment will answer for you:

Innovations in physical experimental instruments can have the following points:

1. Improving the existing experiments in the textbook to make the experiments more concise and cumbersome experiments are more confusing than simple concepts. Therefore, the experimental setup should be concise, the experimental operation should be simple, and the experimental principle should be concise. We should improve some cumbersome experiments in the textbook to make the experiments more concise, and only the "simple" experiments can highlight the key points, which is conducive to concentrating students' attention, helping students to observe experimental phenomena, and more conducive to students mastering the principle of experimental equipment and carrying out experimental operations.

For example, when learning about free fall, using a Newtonian tube to demonstrate experimental free fall can well illustrate that in the absence of resistance, the piece of paper and the piece of iron (metal sheet) are on the ground at the same time. Thus it is possible to:

At the same location, the acceleration of all objects in free fall is the acceleration of gravity. Carefully observing and analyzing, I feel that there are shortcomings in the ointment: first, in the process of reversal, the students' attention is distracted, and the students' attention is focused on the rotation of the glass tube, which is not conducive to observation.

In this regard, the experiment is improved as follows: when designing, the electromagnetic coil is fixed on the top of the iron frame, and 1-2 turns of thin iron wire are wound around the root of the small feather, and the power is turned on, and then the Newton tube pumped as a vacuum is placed horizontally, so that the iron and paper pieces are sucked on the top of the tube, and then the Newton tube is slowly rotated and fixed in the vertical direction, and then the power supply is cut off, and the iron and paper pieces can be clearly seen to begin to fall at the same time, and fall "to the ground" at the same time. Improving the experiment in this way overcomes the aforementioned fly in the ointment and highlights what we are looking at.

2. Change the demonstration experiment to the student experiment to deepen the impression of the students Use the experimental instruments that the students are familiar with to make concise experimental devices, change the demonstration experiment to the student experiment, and let the students change from simple observation and learning to hands-on practical exploration, which can not only help students successfully draw conclusions through experiments, but also enable students to have a deeper understanding of physical concepts and grasp physical laws. In the long run, it is conducive to cultivating students to think independently, explore boldly, dare to fantasize, and create their own new ideas, new problems, new designs, new ways and new methods. When explaining the lesson of "Momentum Theorem", there is an understanding of "buffer", and some teachers use more than ** courseware to demonstrate the small experiment of "Tile Broken Eggs", so that students can see the results of the experiment.

But I think that this experiment only requires equipment: an egg and a sponge, and it is completely possible for students to experiment on their own, so that the students will be very impressed.

3. Use local materials and make self-made experimental devices to strengthen students' understanding of physical concepts The concepts, laws, laws, and laws in physics are often boring and boring, and they do not have the attributes to attract students' attention, and students are often not interested, but they show strong curiosity about strange physical phenomena. Therefore, a successful experiment can induce students to think positively, thereby motivating students' enthusiasm to participate in problem solving, which not only enables students to master the relevant physics knowledge, but also increases students' awareness and ability to obtain knowledge from the experiment.

Infiltrate the sense of innovation in the teaching of science experiments in primary schools.

1. Discover problems, make bold conjectures, and cultivate innovative thinking.

Second, the combination of support and release, independent development, and the cultivation of innovation ability.

3. Give full play to the leading role of teachers and cultivate students' innovation ability.

In the teaching process, students should be at the center of teaching activities. To fully estimate students' learning ability, protect their curiosity, stimulate their enthusiasm, respect their experience differences and learning characteristics, set up appropriate learning paths and evaluation methods for them, and guide them to take the initiative in learning activities, it is necessary to give full play to the role of teachers in guiding, organizing, and supporting, so that students can actively and purposefully carry out first-class learning. "Only by stimulating students' innovative thinking, enhancing students' sense of innovation, and cultivating innovation ability through various ways can we lay a solid foundation for cultivating creative talents in the future.
