Research Into Revision Strategy Of High School Chemistry Academic Level Test,Based On Analysis Of Item Difficulty

High school level test is an important component of the college entrance examination.drawing the attention of the general education workers due to the significance of the test to the students.Research on the overall review strategy is also widely concerned by first-line teachers,but traditional learning started with the strategy from the perspective of examination,focusing too much on pursuit of students' final grades and ignoring the role of the measure to improve students' scientific literacy in all aspects.Rigid exam-oriented education is unfavorable to exert students' learning initiation,so a single review strategy can also be difficult to improve the students' ability and level of thinking.In order to do the chemistry revision effectively,the author,on the basis of literature reference,has studied the education measure theory and the teaching experience of others.With analysis of items difficulty as the breakthrough point,the factors affecting the difficulty of the chemistry test have been found out,through the questionnaire of students and teachers and so have the main reasons these factors,through interviewing students.Attention should be paid to cultivating students' scientific literacy and learning ability,with regard to the factors of influencing difficulty in the review and on the basis of effectively improve students' academic performance.Practical research shows,chemistry test revision strategies,used in the study effectively have stimulated the enthusiasm of students to learn chemistry,improve the students' learning self-efficacy,and effectively help students to transform the original chemical mode of thinking,significantly improving the students' score in chemistry and laying a certain foundation for the physical and mental development of the students fully and personalized development as well as lifelong development.At the same time,teachers of high school chemistry has changed the idea of chemical teaching methods and level test revision.When passing on chemistry knowledge at the same time,pay more attention to inspiring the students' interest in learning,cultivating the students' scientific thinking ability,and caring about students' personalized development.
