About the first lesson of high school biology, high school biology lecture

It has only one cell, and it has to survive, and all kinds of life activities have to be carried out.

Multicellular organisms are made up of cells, the cell is its basic unit, the cell constitutes the tissue, the tissue constitutes the organ, the organ constitutes the system (the plant does not have it), and finally the individual, so it is inseparable from the cell.

The first floor is very good, and the answer to the first question is: it has only one cell, it has to survive, and various life activities have to be carried out.

The answer to the second question is: cellular organisms are composed of cells, cells are its basic units, cells constitute tissues, tissues constitute organs, organs constitute systems (plants do not have them), and finally constitute individuals, so they are inseparable from cells.

Is this clear enough, borrowing the first floor, no wonder.

A single-celled organism is a cell, and multicellular organisms are composed of many cells, so it can be said that there would be no multicellular organisms without cells, and cells are the basis of the life activities of multicellular organisms.

There are books that you pay attention to and you can look for tutorial books.

Strictly speaking, the manuscript consists of the following steps:

1. Briefly analyze the textbook, taking the section on regulation through the nervous system as an example (the content of the class I am talking about today is the content of the first section of the second chapter of the standard experimental textbook biology compulsory three "homeostasis and environment" in the standard experimental textbook of ordinary high school curriculum - "regulation through the nervous system"). The content is taught in two lessons. The first lesson focuses on the structural basis and reflexes of neuromodulation, the conduction of excitation on nerve fibers, and the transmission of excitation between neurons.

The second lesson focuses on the hierarchical regulation of the nervous system and the higher functions of the human brain. ）

2. Expounding the teaching method, how the teacher should use the teaching materials to guide students to study well on the premise of being familiar with the teaching materials, which is a question of teaching methods. Teaching is often done with less effort. When writing a lecture script, you should briefly explain:

the general structure and basis of the Shariah; what teaching methods, teaching methods and reasons were used; Teaching aids and learning aids used. This part is generally covered in a few sentences.

3. Guiding the study of the law.

4. Teaching process. This is the main part, how you design the lesson, how you want to tell the students, in a concise way to explain your teaching process to the teachers. Pay special attention to this, not a lecture, but a lecture.

This also meant that some well-known intellectual content did not need to be explained with as much detail as it was in front of students at the time. Just talk about your teaching ideas. Otherwise, there is not enough time.

The general lecture time is 10-15 minutes. The teaching process accounts for more than half of the process.

5. Analysis of teaching effect. Possible pedagogical effects.

Can only help here, good luck!

Lecturing is to describe your lecture ideas, which are roughly divided into objectives, teaching materials, methods used in lectures and how to design board books, etc., you can go to the Internet to talk about the manuscripts, a lot.

Lecturing should include: teaching materials, teaching methods, learning methods, teaching processes, board books, teaching ideas, etc.

Specifically: 1. When talking about the textbook, we should clearly explain the position and importance of the content taught in the textbook, and at the same time explain the goals and difficulties to be achieved in this lesson.

2. Didactic method is the knowledge teaching method adopted by the teacher in order to achieve the teaching goal of this lesson from what the students' existing knowledge reserves are.

3. In order to achieve the teaching objectives of this lesson, what kind of guidance should the teacher give to the students' learning process and what kind of learning methods to master the skills;

4. Talking about the teaching process, and saying that teaching design refers to the basic process and process of this lesson, you explain it clearly, 5. Talk about the board book (omitted), 6. Talk about the teaching ideas, and talk about the teaching ideas you have infiltrated in this lesson......

So much to say in a nutshell, I hope it will be useful to you.

Good luck with your interview!

In fact, the first lesson is generally an overview and the like.,Those that are partial to history.,It's basically rote memorization.,Just memorize it according to the timeline.,Just watch **.,Understand the stories behind some historical events.,You will find that biology is really interesting.。

Biology is more liberal arts, the focus is still on interest, if you don't learn it well at the beginning, there will be difficulties later, because the content of biology is interlocking, covering a wide range of disciplines, once you lose interest, it is difficult to pick it up.

It is recommended to take a look at the content to be taken before class, so that it is easier to have questions in class.

In terms of knowledge points, you can fill in the knowledge tree on the exercise set, the biological content is more gradual, and the correlation between each content is very strong, as long as you can remember a few key points, the rest can be inferred from each other to remember.

If you can't remember something, you can find similar examples in other disciplines, and biology can easily find similar situations in other disciplines, and it will be much easier to remember.
