Opening remarks for the first class of high school biology! 20

If you don't want to die a miserable death when you graduate, study hard with me.

You've just taken the test, right? You can introduce yourself, chat, talk about your requirements, bottom line, of course, show your enthusiasm for studying with the university, or you can choose a subject representative by the way, so that you can get to know the students faster. At least the list of students can be prepared by them.

Summary. Every year, I basically give a lecture on "Light and Photosynthesis, the Source of Energy". Photosynthesis is one of the most basic metabolisms of the plant body, and it is the basic substance and energy of the biological world.

At the same time, photosynthesis plays a role in connecting the knowledge of cells, ATP, and enzymes learned in Compulsory 1 and the homeostasis and ecosystem knowledge in Compulsory 3. Therefore, it is very important for students to have a firm grasp of this part of the knowledge of photosynthesis. Moreover, the content of photosynthesis is also the focus of the college entrance examination.

High School Biology Compulsory 1 Which one is easy to lecture.

Hello dear, I am a teacher who has been teaching for 10 years, graduated from South China Normal University, is a general knowledge in the field of education, has rich experience in all aspects, I hope that through my experience can really help you. Your question teacher has seen it and is organizing the tease to answer it, please be patient and reply to you immediately! 

Every year, it is basically a lecture on "The Source of Energy, Light and Photosynthesis Stove". Photosynthesis is one of the most basic metabolisms of the plant body, and it is the basic substance and energy of the biological world. At the same time, the photosynthetic dispersion defense has a role in connecting the previous and the next to the knowledge of cells, ATP, enzymes and other knowledge learned in Compulsory 1, and the knowledge of homeostasis and ecosystem of rock in Compulsory 3.

Therefore, it is very important for students to have a firm grasp of this part of the knowledge of photosynthesis. Moreover, the content of photosynthesis is also the focus of the college entrance examination.

Photosynthesis is taught by other teachers and cannot be repeated. Relatively simple, innovative, easy to say, which section is a mess with a higher score, and the first section of the cell is the basic unit of life activities.

It's totally okay, the content is simple, it's easy to understand, and it's perfectly okay to talk about it.

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.

The first biology class in a good high school is of great significance. The first lesson should stimulate students' interest in learning, make students understand the importance of learning biology, understand the learning methods of biology, and cultivate students' biological awareness. The first lesson is very difficult and task-intensive.

The students come from different junior high schools, and the teachers do not understand the knowledge base and personality characteristics of the students. Since biology is a non-college entrance examination subject, society, school, and family have many negative effects on biology teaching. Most students are not interested in biology, are not highly motivated to learn, and lack motivation in their studies, which is the main difficulty encountered in the first class.

In order to complete the teaching task of the first lesson, it is necessary to remove the obstacles in the above teaching, and the following measures should be adopted: the teacher will send a questionnaire during the summer vacation of the first year of high school, which will include: (1) junior high school biology knowledge test questions; (2) What books related to biology have you read? (3) Have you studied all the biology in junior high school?

4) Did you do biology experiments when you were in junior high school? (5) Have you ever participated in a biology competition? (6) Are you a member of the Biology Interest Group?

7) How many species of plants and animals can you recognize? (8) Do you like to raise flowers and raise small animals? At the beginning of the school year, the questionnaire will be collected, and the silver code statistical research and analysis will be carefully carried out, and the first-hand information of the students in the class will be mastered, so that the class can be targeted.

When preparing for the lesson: (1) Collect the resumes of famous Chinese and foreign materialist scholars in ancient and modern times. Such as:

Darwin, Li Shizhen, Mendel, Morgan and Tong Dizhou, etc. Highlight their growth history, major achievements and contributions to humanity. (2) Access.
