Between 3+1+2, the difficulty of biology is indeed lower, and the parents of this generation of children have an inherent understanding of biology difficulty, staying in the period when biology is a sub-subject, or the difficulty and weight of science are small, so as to make the mainstream voice of biological difficulty.
Among the student group, the proportion of students who finally came into contact with the difficulty of thinking in biology physics is relatively small, and a large number of them do not recognize the difficulty of science, but on the contrary, there are more people who think that mathematics and physics are difficult.
Among the four major sciences of mathematics, physics, chemistry and biology, the characteristics and difficulty of biology and physics appear the latest, and from junior high school onwards, learning is a gradual layered process, and the basis for experiencing the difficulty of biology is much less than that of other sciences.
Half of the students in junior high school are diverted, and the main reason why these students are diverted is that they can't learn mathematics, lack of scientific thinking ability, and the difficulty setting of various subjects in junior high school is the same as most people's cognition, that is, mathematics is the most difficult, physics is second, chemistry is again, and biology is not difficult.
The most difficult thing about mathematics is that it has the longest learning time in mathematics, and the knowledge popularization has been basically completed in junior high school, as a learning tool and foundation for science, and the difficulty of mathematics in the second year of junior high school is improved, which not only improves the degree of discrimination, but also the knowledge base and thinking foundation required for the difficulty improvement of other disciplines.
The difficulty of entering the first year of high school physics and chemistry began to be reflected, due to the need for popular knowledge in junior high school, the difficulty of these two subjects is very low, and the first year of high school needs to guide the selection of subjects, so that some students with insufficient scientific thinking will know the difficulty and retreat, including many pseudo-scholars who rely on training in junior high school.
Due to the different bases, 50% of the mathematics stream is not good in junior high school, and they cannot understand the difficulty of the two subjects in the first year of high school, so they think that the difficult base of physical chemistry is smaller than that of mathematics, and chemistry is because of complicated memory, even students who do not choose chemistry think that chemistry is inferior to physics.
Biology is the difficulty only after the selection of subjects, which is why the real scientific thinking of biology needs to have a certain foundation in mathematics and chemistry, so it can experience the lowest proportion of difficulty in biology, plus biology as a scoring subject, even if there is a large gap in the original score, it is not as obvious as the same 100 points in physics after the score, and it will also make people think that mathematics and physics are more difficult from the performance gap.
