In short, it is not to do experimen

In short, it is not to do experiments for the sake of doing experiments, doing experiments is to learn and study the internal relations of things, and master the ways and methods of studying problems. Reform of experimental teaching methods. (1) Observation is the premise of innovation. Observation is the first step of experiment and the premise of innovation. There is no innovation without the understanding of objective things. In the experimental teaching, we should first make students know that the so-called observation is to purposefully identify the main characteristics of the object of observation, pay attention to the conditions and causes of change, and make students understand that observation is to find problems after certain efforts and overcome certain difficulties, in order to get the correct understanding of things and correct conclusions. Students should know that observing things is the first step in extracting a lot of facts, and it is also the first step in any creation and transcendence that we want to do. What we need is not only the results observed by everyone, but more importantly the observation of the activity itself, the observation is everywhere in life. For example, in observing the boiling experiment of water, students are asked to pay attention to what they can see in the process of heating the water supply. On this basis, it guides the discussion on observation methods and problems that should be paid attention to. Different phenomena seen are caused by different reasons, but in terms of the specific reasons, students should draw certain conclusions through multiple experiments, rather than teachers listing various conditions on the blackboard and then providing students with experiments. Doing so actually limits students' thinking, which is not conducive to the formation of innovative thinking. (2) Attach importance to demonstration experiment teaching and strengthen ability training.
