1, which is the main reason that affects the mathematics learning obstacles of senior one students.
Mathematics in senior high school is a difficult course. According to the psychological characteristics of junior high school students, the present situation of junior high school teaching and the expansion of senior high school scale, the main factors affecting students' learning senior high school mathematics are: the basic knowledge is not solid; Insufficient guidance on study habits and methods; Without adequate psychological preparation, the psychological endurance is not strong; Interference and influence of non-intellectual factors; Another point is more important, that is, the strong contrast between the teaching contents, requirements and teaching methods of junior and senior high schools; The teaching level of mathematics teachers in senior one is uneven.
(1) Basic knowledge is not solid.
Affected by the pressure of entering a higher school, in order to have more time to review for the exam, students will squeeze the time of the new course and delete the content that is not included in the exam or what they think is not important. This will lead to students' incomplete learning structure and poor mastery of basic knowledge. For example, junior high school students will be confused if they don't have enough time to learn the new courses of function and plane geometry. With this shadow, students will feel scared when they meet the study of functions and solid geometry in high school, and they will feel afraid of difficulties if they don't learn.
(2) The instruction of study habits and methods is not enough
Teachers in junior high schools generally don't pay much attention to the guidance of students' study habits and methods, and are likely to ignore the cultivation and infiltration of mathematical thinking methods (students' cognitive level is acceptable now). Teachers will let students master problem-solving methods through a lot of practice imitation, such as learning quadratic function in junior high school.
(3) Lack of psychological preparation, weak psychological endurance and interference from non-intellectual factors.
Junior high school students will pass the senior high school entrance examination, especially in key middle schools. Students will enter high school with the joy of victory, full of pride and hope, and most students will also want to show their talents in high school mathematics learning and get high marks like junior high school exams, because they are "excellent students" in junior high school, often concerned and praised by teachers, and grow up with flowers and praise. There will be a sense of pride and superiority in my heart. When entering high school (especially key middle schools), the top students are relatively concentrated, and their math scores may not be absolutely dominant. I also face fierce competition. Students' common sense of superiority and pride, which is not taken care of by teachers in time, is likely to lead to the loss of self-confidence and the enhancement of inferiority. Some students unilaterally think that they will get what they want after one year (or even months of hard work). After entering high school, I want to play first, and then try to enter the university. I am not fully prepared for the difficulty of studying in high school. Students encounter difficulties and have insufficient psychological endurance. Therefore, when they enter high school, they feel uncomfortable and will encounter obstacles in learning mathematics.
(4) The sharp contrast between junior high school and senior high school in teaching content, requirements and teaching methods.
With the continuous advancement of curriculum reform and nine-year compulsory education in junior high school, junior high school mathematics has been deleted and the requirements have been lowered. However, the teaching content of senior high school has added a lot of content to the experimental revised textbooks currently used. Moreover, the college entrance examination can be said to be very fierce competition. The adjustment of the direction of college entrance examination questions (from focusing on knowledge to focusing on ability in the past) will lead to the "strategic" adjustment of senior high school mathematics, catch up with the teaching progress and end the new curriculum ahead of schedule. There is always time for review, regardless of the reception level of senior one students. The focus of high school mathematics is to cultivate thinking ability, analyze and solve problems, and strengthen thinking training. Instead of strengthening knowledge mastery and problem-solving training in junior high school, this different orientation will inevitably raise the requirements for students, which is an important factor for freshmen in senior high school to feel uncomfortable.
