First, adjust the arrangement system of teaching materials and highlight the practice of knowledge topics.
Teaching activity is a systematic project, which consists of teaching materials, teachers and students. Among them, the textbook is the blueprint for imparting knowledge to students, limiting the scope of knowledge and controlling the teaching level, which is the concrete embodiment of the syllabus.
Practice has proved that teaching without textbooks is largely blind. The teacher completely follows the book, and even if the students recite the textbooks, they can't meet the needs of cultivating talents. Therefore, the important role of teachers is to thoroughly understand the knowledge structure of teaching materials and reasonably organize knowledge topics for teaching.
1, adjust the chapter order according to the knowledge order.
2. Organize knowledge topics according to the network nature of knowledge.
Second, according to students' cognitive rules, strengthen the cultivation of thinking ability.
Thinking is the main psychological process for people to acquire rational knowledge and the core of chemical ability structure. In the teaching process, combining with chemical materials, students can form feelings, perceptions and concepts in perceptual knowledge, and then form concepts, laws and theories through rational knowledge, which are inseparable from the cultivation and exercise of scientific thinking. How to combine the age characteristics and cognitive rules of middle school students to cultivate and develop students' thinking ability?
1. Overcome the mindset and cultivate students' divergent thinking ability.
2. Cultivate students' reverse thinking ability by changing a topic.
Third, tap the inherent law of knowledge and pay attention to the guidance of learning methods.
The characteristics of chemical knowledge are "many, chaotic and miscellaneous". Difficult to learn and difficult to remember, students regard it as a "second foreign language". In order to eliminate this psychological obstacle of students, we apply scientific thinking methods to help students sort out and summarize, and strive to concretize abstract knowledge; Macro knowledge; Random knowledge is organized. Step by step, strengthen mastery.
Interpretation of scientific thinking methodology papers;
Scientific methodology is the abbreviation of "methodology of natural science". The concrete embodiment of Marxist epistemology also summarizes and summarizes various cognitive methods of natural science. The steps involved in it, such as observation, experiment, determination, data processing, classification, hypothesis, hypothesis verification and conclusion, reflect the general law of chemical research methods.
Therefore, scientific methodology is an important theoretical basis for correctly understanding chemical knowledge, and it is also the basic way and step to cultivate chemical problem-solving ability.
