How do I take an open class for the Chemistry Review Class in the third year of junior high school?

It's good to have a lot of help.

I used to take the "metal activity sequence" review of the regional-level open class, more than ** classroom there are nearly 300 teachers listening to the class and 80 students in class, their own courseware, from the introduction of new lessons, the main review points, knowledge network, student experiments, example analysis, classroom exercises and other aspects can be interspersed freely, the classroom form has explanation, animation, **, etc., students like it very much, said that even the teacher who came to listen to the class did not feel that the review was fried rice. Of course, this requires good courseware creation inspiration and multi-processing technology for text, animation, sound, and image.

It's awkward to take a chemistry review class.

My opinion is: more ** teaching.

Students can repeat the key points of the unit, or use the key topics to lead and discuss, and more ** can summarize the knowledge points or arrange key experiments. This is more innovative and absolutely avoids talking about the topic.

The class capacity should be large, carbon should be the main line, from elemental matter to compound, from properties to production methods, and students will discuss the equipment and CO tail gas treatment, focusing on the production method and environmental protection of CO2, I think you will definitely have a good method.

Upstairs, others are taking public classes for review, not new classes, aren't you harming others by taking them like that!

I felt like the teacher could do experiments with a bottle of Coke. Add anecdotes. Hey. Then look for a few samples.

Glass cutter. Pencil or something. Personal opinion.

1. Demonstration experiment, doubtful thinking: Demonstration experiment teaching, before the demonstration, explain to the students the content of the experiment, the purpose of the experiment or the phenomenon of observation, and tell the students what should be observed. Carefully lay out some necessary ladders to set up questions and stimulate students' thinking.

2. Student experiments and innovative thinking: Student experiments are not only an important means for students to learn chemistry well, but also play an important role in cultivating students' innovative thinking, enhancing their sense of innovation, and developing innovative thinking habits.

3. Improve experiments and form experimental ability: In chemistry teaching, in order to help students form experimental ability and cultivate students' ability to innovate, some experiments can be improved.

4. Increase interest in experiments and stimulate interest: Chemistry is a natural science based on experiments, and a large amount of material knowledge, laws, and theories are based on experiments. As a practical activity, students can learn to observe things, measure data and analyze data to make bridges, and form thinking methods such as analysis, comparison, synthesis and generalization in the process of explaining experimental phenomena and analyzing experimental results.
