How junior high school chemistry guides students to self directed learning

How to guide children to take the initiative to learn.

Self-directed learning: a modern way of learning.

Learning should be arranged with a simple and feasible plan to improve the learning method. At the same time, it is also necessary to participate in school activities appropriately and develop in an all-round way.

In the process of learning, we must: listen more (listen to lectures), remember more (remember important sample essays, concepts, and formulas), read more (read books), do more (do homework), ask more questions (ask if you don't understand), do more hands (do experiments), review more, and summarize more. Use the method of taking class notes to focus on the lesson.

Read more important texts in English, and be familiar with vocabulary and usage.

In other times, we must ensure the study time, ensure the learning quality of each subject, and not deviate from the subject.

Get enough sleep every day to ensure your learning efficiency.

Arrange appropriate free time for socializing with family and friends and other activities.

Through unremitting efforts, the results are improved and stabilized step by step. Do your best for the exam, be careful during the exam, and be calm when you sprint at the end. After the exam, you should summarize carefully so that you can study better in the future.

Right now: let go of the baggage, usually: study hard. Before the exam: prepare carefully, during the exam: don't give up, after the exam: normal heart. Remember!

Self-directed learning: a modern way of learning.

The discipline of chemistry has two main characteristics:

1) Chemistry is a natural science based on experiments, and the formation and development of this discipline originates from and depends on experiments.

2) Chemistry is "complicated".

This "complexity" actually reflects the characteristics of the fact that the knowledge points of chemistry are both numerous and scattered, and a large amount of knowledge needs to be memorized. Therefore, we should not copy the previous methods of learning mathematics and physics to learn chemistry, but should choose and innovate according to the characteristics of the discipline

1) Observation "Observation" means to observe.

In chemistry experiments, we should cultivate our own good observation habits and scientific observation methods, which is one of the important conditions for learning chemistry well. So how do you observe the experiment? First of all, we should pay attention to overcoming the interest of curiosity and fun in observation, and we should be clear about "what to observe" and "why", and observe experimental phenomena in a planned and purposeful manner under the guidance of the teacher.

Observations should generally follow the sequence of "before-during-post-reaction". The specific steps are:

1) The color, state and odor of the reactants; (2) reaction conditions; (3) various phenomena in the reaction process; (4) The color, state, and odor of the reaction products. Finally, under the guidance of the teacher, the observed phenomena are analyzed, judged, synthesized and generalized, and scientific conclusions are drawn, accurate concepts are formed, and the purpose of understanding and mastering knowledge is achieved.

2) "Moving" means actively experimenting.

As the saying goes, "it is better to see than to hear, and it is better to see than to test", hands-on experiments can not only cultivate their own hands-on ability, but also deepen our knowledge, understanding and consolidation, and improve learning efficiency exponentially. For example, the principles and operating steps of oxygen production in the laboratory can be mastered much faster and more firmly than just watching the teacher do it and memorizing it yourself.

3) Remembering: "Remembering" means memorizing.

Compared with mathematics and physics, "memory" is particularly important for chemistry. Chemistry is a "liberal arts subject in science", and there are many knowledge points in junior high school chemistry, which involves a wide range of topics, and is easy to learn and difficult to remember. Students generally responded to chemistry lessons"I can learn it, but I can't remember it"In response to this situation, it is necessary to memorize!

To memorize valency, relative atomic mass, metal activity, etc., only if you memorize it well, you can learn chemistry! Therefore, it is necessary to strengthen memory training, flexibly use memory methods, and improve memory effects.

Why does chemistry take memory very seriously, this is due to:

l) Chemistry itself has a unique "language system" - chemical terms. For example, the mastery of these chemical terms is the first task of the introduction to chemistry, and most of them must be memorized.

Self-directed development depends on the student's own semester situation. If you are a teacher, you can mentally divide the students according to their abilities, and then give them tasks of different difficulty to complete independently.

The reform of chemistry teaching is both an opportunity and a challenge for me, and it requires chemistry education to embark on the road of adapting to the needs of social development, academic development and students' personality development. China's implementation of the nine-year compulsory education program reform, requiring teachers not students to drown in the flood of materials, to tutor and participate in evening, fake tutoring as a fashion, instead of teachers to provide students with opportunities, create conditions, can be in the classroom...
