Throughout the preparation process, I found that students participating in enthusiasm high, cooperate do well, not put forward a lot of interesting questions, they feel the experiment in the process of glamour, also felt setbacks, that is what we education should meet, but we've ever used too much of a sermon replaced, such as a group of students want to study the influence of catalyst on chemical reaction, they want to use research various catalyst for hydrogen peroxide decomposition of influence, and by using pressure sensor to measure the oxygen produced much, this is a very good idea, but has trouble, carries on the early experiments found that produced gas overmuch, in airtight container, measuring pressure is very dangerous, the group's classmates will explore further containers.
Another group to determine the quality, the alcohol Moore is of significance, but the problem is, how to constant quality of liquid alcohol into gases, by means of measuring the pressure and temperature measurement Moore quality, they haven't think good, I think encounter problems are good, we need to cultivate creative talents, in such exchanges, I saw the shadow.
Anyhow, I want to do what topics, all is the carrier, my aim is through the communication, enhance mutual understanding, friendship, more enough mutual learning, change their intrinsic mode of teaching and learning model, trying to explore, which not only conforms to the condition of a country, and efficient teaching and learning mode, students will be made in reducing load conditions, to learn more interested in, the more active, to the question of understanding deeper, more healthy, happy, learning, I'll say this much, thank you.
In the preparation process, I found the enthusiasm of the students involved in the high division of labor done well, do not make a lot of fun when the problem, they felt during the experiment in the charm, but also felt the frustration, which is what we education should be met, but we have in the past too much preaching instead of, for example a group of students want to study the impact of catalyst on chemical reactions, they want to use of various catalysts on the decomposition of hydrogen peroxide, and the use of pressure sensor to measure the amount of oxygen produced, this is a good idea, but in trouble, the early experiments found that the gas too much, in a sealed container, the determination of pressure is very dangerous, this group of students will further explore the problem of the container.
Another group to determine the molecular weight of alcohol, which is of great significance, but the question is, how the quality of the liquid alcohol into a gas constant, by measuring the pressure and temperature to the measured molar mass, they are not ready yet, I that a problem is good, we need to develop creative talents, in this exchange, I saw this shadow.
In short, what kind of issues I want to do, are carriers, my purpose is communication, enhance understanding, promote friendship, but enough to learn from each other, change their inherent mode of teaching and learning, and strive to conform to their national conditions to explore a , and efficient mode of teaching and learning so that students can reduce the load conditions, to learn more interested, more active, more profound understanding of the issues, more healthy, happy learning, all I can say, Thank you.
