A teaching method for learning organic chemical structure formula

Abstract

A teaching method for learning and teaching organic chemical structures, which involves a teaching method. Step 1: build a tray: take several trays (1), and place the sockets (37) and posts on the side walls of each tray (1) (38) Interlocking and splicing into a large-area plate; Step 2: organic structure splicing: carbon-carbon connection: take out an appropriate amount of carbon chess pieces (4) from the drawer (6), and pass the carbon chess pieces (4) through the bottom of the drawer The inverted T-shaped outriggers (14) are movably inserted on the slideway (2) with a "convex" cross-section; the teaching method of the present invention allows students to operate by hand, splicing a structural formula of organic matter, so that organic chemistry learning has A certain amount of fun can enhance students' interest in learning and at the same time deepen students' understanding of chemistry learning interest and chemical knowledge, which is very conducive to chemistry learning.

Description

technical field [0001] The invention relates to a teaching method, in particular to a teaching method for learning organic chemical structure formulas. Background technique [0002] High school is a critical moment in the student period, when basic knowledge is laid. High school chemistry involves many aspects of knowledge, such as chemical experiments, chemical reaction rates and chemical equilibrium, chemical reaction types, electrolyte solutions and chemical calculations, elements and their Compounds, etc., so that students can understand chemical knowledge from many aspects, which will also involve the study of the basics of organic chemistry, which is a part of the chemistry curriculum with a lot of content and strong variability. In the college entrance examinations over the years, the form of organic chemistry exam questions has not changed much, but the content is rich, the amount of information is large, the comprehensiveness is strong, and there are many growth poi...

AI Technical Summary

Problems solved by technology

[0004] 1. At present, in the study of the basics of organic chemistry in high school, students' learning effect is not good, and the score rate in large-scale exams is not high. At present, there is no relevant auxiliary learning tool on the market, so there is an urgent need for a learning device to assist students in learning the basics of organic chemistry ;

[0005] 2. In the basic study of organic chemistry in high school, according to the analysis of the structural characteristics of carbon atoms, carbon atoms have four covalent electrons, and form four covalent bonds with carbon atoms or other atoms; it may be single, double or triple bonds, and may be Forming a chain or a ring, the content is relatively abstract during the learning process, and students cannot clearly understand the structure of organic matter when learning, resulting in poor chemistry learning results;

[0006] 3. In the basic study of organic chemistry in senior high school, there are many types of organic substances involved. For example, organic substances with the same number of molecules may have multiple structures, and carbon atoms are connected into different chains or rings. 5 h 12 There are three isomers, namely, n-pentane, isopentane and neopentane. Most of the students' memory process is through rote memorization, which often wastes a lot of time to memorize, but the memory effect is not deep enough and not firm enough. Can not be flexibly applied in the middle, resulting in poor chemistry learning effect;

[0008] 5. In the preliminary study of the basics of organic chemistry, when studying isomers, students are often required to give examples of isomers produced by different chain or ring structures connected between carbon atoms. Due to the large number of types, students will waste a lot of paper when enumerating on paper, which is not conducive to environmental protection. At the same time, it is easy to make mistakes in drawing covalent bonds, and there are too many types of structures to reduce students' interest, which is not conducive to improving the learning effect of chemistry. ;

[0009] 6. During the initial learning process of students, it is difficult to figure out which part of the carbon bond in the chemical reaction of organic matter changes through the teacher's written explanation, and it is impossible to deeply understand the principle of chemical reaction change. Similar types are involved in the test , properties of organic compounds, students can easily fail to write the equations of chemical reactions correctly, resulting in loss of points

[0010] Organic chemistry is a very important branch of chemistry. The study of the basics of organic chemistry in high school will link up with the study of organic chemistry in universities. , there are still problems mentioned above that cannot be solved well, resulting in poor learning effect of organic chemistry for students. Therefore, researching a device to assist students in learning the basics of organic chemistry has great teaching significance and social value
