Chemistry questions often appear in the form of test questions, because it is a new subject in the third year of junior high school, there will not be too much difficulty and knowledge of thinking, and the thinking system of the discipline is also difficult to establish, which makes it difficult to focus on the investigation of logical thinking ability (chemistry is a very examination of logical reasoning ability), and as a discipline that calculates the total score, it is necessary to establish a certain degree of distinction, so the discussion of experimental questions has become the easiest question type to achieve.
Most students tend to answer the objective questions in chemistry, there is not much difference, the answer standard and the difficulty is not great, but the subjective wheel speed questions are very different, the experimental principles or reaction phenomena that require the exposition of the emphasis are memory, but this memory does not rely on the fuzzy memory on the basis of understanding, and then organize the language to elaborate reasonably. This is also the way that many students with strong scientific thinking skills memorize, but pursue the standardization of answers, but those students who memorize by memorization have more advantages.
As a result, not only is there no obvious gap between eugenics and ordinary students in the subject of chemistry in junior high school, but also the advantages of students with good scientific thinking in mathematics and physics are not obvious, and their independent thinking ability cannot be fully utilized.
This is also why many people think that chemistry is simple and can be learned by rote memorization, but after entering the first year of high school, chemistry is still based on memory, but the memory mode is very different from that of junior high school, it is a large amount of memory in understanding and situational use, and it is necessary to establish a thinking system to effectively connect the complex memory points, memory is only the basic ability, and it is the key to be able to use it flexibly and reason and analyze in the scene. High school chemistry, especially after the selection of subjects, enters the organic chemistry part, and the requirements for logical thinking ability are no less than mathematics and physics.
Therefore, in junior high school, it is often difficult for students with good scientific thinking to fully show their advantages, especially physics and chemistry, not only the difficulty of junior high and high school is not connected, but the subject characteristics are completely different.
