The high school entrance examination to the first year of high school, less than half a semester, has caused many students who have worked hard for nine years to suddenly drop their grades, especially the three science subjects of mathematics, physics and chemistry.
Objectively speaking, the reason why the phenomenon of falling behind is extremely common is related to the lack of difficulty in junior high school and the moisture caused by training.
The distinction of junior high school physics examination focuses on electricity, and the more basic acousto, light and heat occupy a large area, these knowledge points are not inherited from the mechanics part of the first year of high school, and the most undertaking part of physics and mechanics in the second semester of the second semester of junior high school has limited difficulty expansion and limited examination weight, so that the real physical thinking can not be reflected in junior high school.
In the ordinary teaching examination in the second semester of the second semester of junior high school, the mechanics part has formed a more obvious distinction, but this distinction is cleared in the third stage of junior high school, and behind the general high score in physics in the high school entrance examination, the gap in the mechanics part of the real thinking ability is diluted.
The confusion of chemistry in junior high school is more obvious than that of physics, and many students' knowledge of chemistry by rote memorization is mostly derived from the discipline cognition in junior high school.
Because it is a new discipline, junior high school chemistry will not quickly enter the stage of competing for scientific thinking, but as an examination subject, it is necessary to establish a certain degree of distinction, physics can be reflected in electricity as a few difficulties, chemistry relies more on the meticulousness of answering questions, especially a large number of essay questions, students with good scientific thinking, relying on the language of thinking organization, are indeed not as good as students who simply memorize students with strong scientific thinking, and often have no way to exert force in chemistry.
The difficulty of mathematics is higher than that of physical chemistry, but it often has higher grades and confusion, that is, excessive training, and most of the training in order to achieve a more obvious effect of improving scores, often dilute the thinking and form a set of questions proficiency with mechanical training models.
Without training, students who are able to excel in mathematics and physics in the second semester of junior high school tend to have greater learning potential in high school.
