With the understanding of professional development, more and more teachers realize the necessity of doing research. However, some teachers' understanding of this subject is still not in place. The following are the true words of several teachers.

"I just write in the form of a paper, right?"

"I started writing papers from middle school. Why does another' topic' come up to play concept games? "

"I won't do it, but I will hand it in."

"The topic is not a paper? Why are there' variables'? "

I'm not an expert in this field. To be honest, I had the same confusion at the beginning. I also listened to some experts' reports, such as "from topic selection to data search, to hypothesis, to experimental demonstration" and so on. Finally, I was at a loss.

So I can understand that many teachers ask me the above questions.

In order to help teachers distinguish between "topics" and "papers" as soon as possible, I simply said: "The topic is to prove whether a proposition is established through experiments. The thesis is to use truth. "

Of course, my understanding is not comprehensive and scientific, but it is beneficial for teachers to understand the subject initially according to the viewpoint of "persuading learning (first give way to knowledge, then let it go back)"

As for the understanding of "variables", science teachers may not have much difficulty, and liberal arts teachers have a little difficulty. For the sake of understanding, let me give you an example:

Zhang San kept goldfish at home, but they always died within a few days. They died after raising them, and they died after raising them. (the status quo, that is, the background of the problem)

So he thought, "How to make goldfish grow healthily?" (The topic he chose was "Study on the Healthy Growth of Goldfish")

So he thought, "the growth of goldfish can't be separated from factors such as boiling water, temperature, sunshine and food." He found four variables: water, temperature, sunshine and food.

So Zhang San thought, "How much water, how much temperature, how much sunshine and how much food are most suitable for the growth of goldfish?" So he tried. He conducted control experiments on variables.

After many experiments, he found that "X amount of water, Y amount of temperature, Z amount of sunlight and R amount of food" are the most suitable for goldfish growth. His research has yielded results.

He will keep goldfish like this in the future, and he also tells others his experience. Later, many people raised goldfish in his way, but none died and all grew up healthily. He popularized his research results.
