A Study On The Consistency Of New Textbooks And Curriculum Standards In High School Chemistry In Peoples Education Press

Based on the background of curriculum reform,in order to verify the consistency of the new textbooks on general high school chemistry in peoples education press and the standards of general high school chemistry(2017 edition),the following four main problems are proposed to be solved on the basis of an overview of the relevant literature,textbooks and curriculum standards:(1)Analysis of chemistry new textbooks and ordinary high school chemistry curriculum standards are consistent with Porter.(2)Whether the new textbooks and curriculum standards of analytical chemistry have significant consistency in cognitive dimensions.(3)Analysis of chemistry new textbooks and curriculum standards in the content of the topic of whether there is significant consistency.(4)Analysis of chemistry new textbooks and curriculum standards in the key distribution of whether there is significant consistency.To this end,the following research steps have been taken to address the four aspects mentioned above.Firstly,the research methods used in the consistency analysis are considered,and the most appropriate research methods are found in the consistency analysis;Secondly,the content subject dimension is determined according to the subject in the standard of general high school chemistry curriculum;The cognitive level dimension is determined by the setting of the Bloom education target classification,and the curriculum standard is coded separately with the content of the new high school chemistry textbook;And the final statistical analysis of the coding results is carried out.Following the above research steps,you can obtain the following results of the analysis:(1)Porter consistency coefficient.It is found that the first and second volumes of the new high school chemistry textbooks have significant consistency with the Porter consistency coefficient of the curriculum standard.(2)Comparison of content topics.The ratio difference between the new high school chemistry textbook and the curriculum standard theme 1,the topic 2 and the knowledge points contained in the topic 4 is less than 0.05,and there are some differences in the ratio difference of knowledge points included in topic 3 and subject 5,but from the overall analysis,it can be found that it has good consistency.(3)Comparison of cognitive level.The ratio difference of the knowledge points included in the new high school chemistry textbook and curriculum standard in mastering and application level is less than 0.05,and there is some difference in the ratio difference of knowledge points included in the knowledge level of knowledge and understanding,but it has good consistency from the overall analysis.(4)Key distribution.There are similarities and differences between the new high school chemistry textbooks and the chemistry curriculum standards.From this,the following conclusions are drawn:(1)The new chemistry textbook and the chemistry curriculum standard have good consistency in the Porter consistency paradigm.(2)The new chemistry textbook and the chemistry curriculum standard have good consistency in the content topic.(3)The new chemistry textbook and the chemistry curriculum standard have good consistency in each cognitive theme.(4)The new high school chemistry textbooks and the chemistry curriculum standards have the similarities and differences in the content of the topic and cognitive level.
