What is lecture?

Lecture lecturing is when the teacher verbally expresses the teaching ideas and theoretical basis for specific topics. That is, the teacher talks about his teaching design in front of peers or teaching and research personnel on the basis of lesson preparation, and then the listeners comment. , a teaching research and teacher training activity that achieves the purpose of mutual communication and joint improvement.

Practical teaching:

1. Teaching materials: mainly talking about the brief analysis of teaching materials, teaching objectives, key points and difficulties, class schedule, preparation of teaching aids, etc. These can be simply said, The purpose is to let the audience understand the content of your lesson.

2. Preaching method: It means to talk about which teaching method you plan to use based on the teaching materials and the actual situation of the students. This should be the general idea.

3. Talking process: This is the focus of teaching. That is to say, how do you plan to arrange the teaching process and why do you want to arrange it this way. Generally speaking, you should clearly explain several key aspects of your teaching.

There is a certain difference between theoretical lecturing and practical lecturing. Practical lecturing focuses on the process and basis of teaching, while theoretical lecturing focuses on talking about one's own opinions. Generally speaking, theoretical lectures should include the following aspects:

1. Talking about viewpoints: Theoretical lectures are lectures focusing on a certain theoretical viewpoint, so we must first make our own viewpoints clear . What you support and what you oppose must be clear-cut.

2. Talk about examples: Theoretical points must be confirmed by practical examples. When lecturing, you should quote appropriate and vivid examples to illustrate your point of view. This is the focus of lecturing.

3. The role of lectures: lectures are not purely theoretical exchanges. They focus on the combination of theory and practice. Therefore, we must combine our own teaching practices during lectures to clearly explain the role of this theory in teaching.

Notes:

Establishing teaching focus and difficulties is a content that must be explained in lecture activities. To determine the key points and difficulties, it is necessary to figure out what knowledge is the key point and analyze how the learning difficulties are formed.

The teaching focus refers to content that is unique and has important value (including cognitive value, transfer value and emotional value). From the perspective of chemistry, the key knowledge in teaching mainly includes core knowledge (basic concepts, basic theories, important knowledge of elements and compounds), core skills and core ideas and perspectives.

The study of these contents is not only conducive to the systematization of knowledge itself, but also conducive to the improvement of students' ability levels.

Difficulties are content that is difficult for students to understand and master. Learning difficulties mainly include the following aspects:

1. Students have no knowledge base or have a very weak knowledge base;

2. Students’ original experience is wrong;

3. Content learning requires changing the thinking perspective (such as from macro to micro);

4. The content is abstract, the process is complex, and it is highly comprehensive. Content with one or more of the above characteristics may become a difficulty in teaching.
