The top ten memory methods of the senior high school entrance examination

First, simplify the memory method

This is an effective method for the main steps of the memory chemistry experiment. On the basis of understanding, it is memorized by a few words or words composed of a refined word. Such as: composed of six words: "one, two, three heating", this sentence summarizes the key steps and precautions of hydrogen reduction of copper oxide, greatly simplifying the memory.

Second, understand the memory method

Analyze, synthesize, compare, summarize and summarize the knowledge learned, find out the internal connections and laws, and then memorize these knowledge with regularity. For example, the concepts of memory element symbols, molecular formulas, and atoms must be remembered on the premise of understanding.

Third, interesting memory method

In order to spread the difficulties and increase interest, we should use interesting memory methods to memorize relevant chemical knowledge. For example, hydrogen reduction copper oxide experimental operation is available: "hydrogen gas comes out early and returns late, alcohol lamp is late to leave early. The former is reversed to explode, the latter is reversed to be oxidized."

Fourth, repeated memory method

To use the necessary repetitions to deepen the impression of remembering things is also an effective way to fight forgetting, so when you remember some knowledge, you often use silent repetition and narrative reproduction to deepen your impression.

V. Editing the slogan memory method

There are a lot of knowledge in the middle school chemistry, memory is difficult, but also commonly used, but it is very suitable for editing the jingle method to remember. For example, when learning the relationship between valence and chemical formula, you can use "a row of sequential two-price, absolute price to cross, accidental corner code to reduce, write a good formula to check."

Sixth, classification memory method

Systematize the knowledge learned and grasp the characteristics. For example, when remembering the properties of various acids, first classify them, remember the acidity of the acid, and add the characteristics of several common acids to know the chemical properties of the acid.

Seven, contrast memory method

Compare the relevant knowledge of similarity and opposition between old and new knowledge to find similarities and differences.

Eight, associative memory method

Compare the characteristics of the same, similar, and opposite things, remember the difference between them, and when you recall, you can think of others as long as you think of one. Such as: remember the solubility of acid, alkali, salt, do not remember in isolation, to expand Lenovo.

Nine, keyword memory method

This is one of the effective methods of memory concept. On the basis of understanding, find a few keywords or words in the concept to memorize the whole concept, such as: can change the chemical reaction speed of other substances and its own quality and chemical properties before and after the chemical reaction The connotation of this catalyst can be changed: "One change two unchanged" several keywords to remember.

Ten, knowledge network memory method

Use tables or diagrams to summarize and organize, so that seemingly fragmented knowledge is networked.
