Research On Cognitive Dimensional Analysis Method And Application Of High School Biology Unit Test Paper

Bloom’s Taxonomy of Educational Objectives is the first systematic theory of educational objective classification in the history of education.The 2001 revision of Bloom’s Taxonomy of Educational Objectives is an extension and deepening of the1956 taxonomy,which transforms the single dimension of the cognitive domain into two dimensions,namely the knowledge dimension and the cognitive process dimension,and has been widely used.In terms of the classification of teaching objectives,the design of teaching activities and teaching evaluation.Since the 2017 edition of the high school biology curriculum standard was promulgated,how to conduct teaching evaluation based on the core literacy of the subject has become a new topic in teaching research.Based on the revised Bloom’s taxonomy of educational goals,this article explains the method of unit test paper analysis,and specifically analyzes the two unit test papers,aiming to distinguish different cognitive levels and levels in order to facilitate relevant teaching and promote students’ ability Cultivation.This research uses the literature research method to sort out and analyze the current research status of Bloom’s educational target taxonomy at home and abroad;use text analysis to analyze the teaching supplementary materials "Textbook Gang" high school biology compulsory second chapter second chapter unit test papers Analyze the cognitive process dimensions of the examination and construct related analysis methods;use case analysis to analyze the cognitive process dimensions examined in the test papers of the first-year mid-term exam of a school in Yichun City,Jiangxi Province,and analyze students based on their answers Cognitive ability.Through the above research,the following conclusions are drawn:Bloom’s Taxonomy of Educational Objectives can classify test questions and construct scientific analysis methods;by analyzing the cognitive dimensions of the unit test papers in Chapter 2 of the Compulsory Teaching Material Help,it is found that the test questions are mainly focused on the levels of understanding,application,and analysis.,Which shows that it pays attention to the understanding,application and analysis of knowledge.In the analysis of the mid-term test papers of a school in Yichun City,Jiangxi Province,it is found that the test papers as a whole focus on the examination of lowlevel cognitive levels,that is,recall,understanding,and application levels;in the highlevel levels,it mainly examines students’ analytical ability.It focuses on the basics.Analyzing the students’ answering situation,it is found that the memory test questions are better mastered;the students in different ranks have different cognitive abilities,and the top students have better cognitive abilities;the students with the same score have different cognitive ability structures.Individualized teaching can be carried out according to the differences of students,so as to teach students in accordance with their aptitude.
