A Comparative Study Of Test Questions In The Chemical Experiment Questions In Senior High School Entrance Examination

Senior high school entrance examination's function is to screen the appropriate level students to enter the high school study,which is an important selection test in China.Chemistry experiment questions in senior high school entrance examination is related to chemistry experiment in junior middle school chemistry class,and the specific experimental situation as the manifestation.The function of examination questions is to examine whether the students master the related basic knowledge and skills of junior middle school chemistry lessons,and examine the formation of students scientific inquiry ability.Through the 2011-2017 years of the Beijing,Tianjin and Hebei Chemical examination questions were carefully read,combed and classified statistics,and reference related research literature.It can be divided into five parts: "the distribution of experimental questions","the scope of examination questions for experiments","the new situations of experimental questions","the distribution of knowledge of experimental questions" and "the presentation of experimental questions".Excel and other tools are used for statistical analysis,and the following conclusions are drawn.(1)Beijing,Tianjin and Hebei Chemical experiment questions in senior high school entrance examination questions in the test questions,scores and fill in the blanks position is relatively stable;Beijing and Tianjin only a single choice,and that Hebei has a multiple-choice test questions;Beijing,Hebei and Tianjin location is random,fill in a fixed position.(2)In the Beijing,Tianjin and Hebei senior high school entrance examination,the chemical experiment questions all emphasized the examination of "experimental operation","experimental phenomenon","experimental principle" and "experimental conclusion".Besides,Tianjin also attached importance to the examination of "experimental instruments";Hebei tried to test "guess hypothesis".(3)There are daily life phenomena,chemical magic tricks,natural growth points of junior middle school chemistry and some high school chemistry knowledge situations in the chemical experiment questions of Beijing,Tianjin and Hebei senior high school entrance examination,.(4)From the knowledge aspects of experimental examination,the most frequent examination questions in Beijing,Tianjin and Hebei senior high school entrance examination of chemistry experiment are two knowledge points: "mass conservation law and chemical equation" and "common acid,alkali and salt".In addition,Beijing on the "air" examination,Tianjin on the "water and solution" test frequency is also higher.(5)In the number density and the fluctuation degree of chemical experiment test in senior high school entrance examination,according to Tianjin,Hebei and Beijing in the order of increasing;in the questions presented in the way of chemical experiment test in Beijing,senior high school entrance examination in Hebei and Tianjin have adopted the text,table,graph rendering device,Beijing also tried a variety of illustrations,as flow chart presentation,etc.In view of the above conclusions,the following suggestions are put forward:(1)Teachers should improve the level of daily classroom teaching and help students to implement basic knowledge.(2)Schools and teachers should attach importance to chemical experiments and strengthen the students' experimental skills.(3)Teachers and students should jointly create opportunities,develop material for scientific inquiry,and cultivate students' core literacy in the process.
