Research On The Construction And Application Of Discipline Core Competencies Evaluation Index System Based On Bloom’s Taxonomy Of Educational Objectives

Nowadays,the competition among nations is becoming more and more intense,fundamentally,it is a competition for talent.After multiple curriculum reforms,China has changed from "Dual Foundation" to "Tridimensional Target",and now to the latest curriculum standards with "core competencies" as the core,which increasingly focuses on the development of student abilities.The Discipline core competence is the essential character and the key ability of the student,which can adapt to life and society development needs.The country attaches great importance to the improvement of students’ the core literacy of information technology,so how to efficiently cultivate and accurately evaluate students’ core literacy in the field of information technology has become an urgent core issue that needs to be addressed.The Analytic Hierarchy Process(AHP)was used in this research.to construct junior high school information technology core competency evaluation index system based on Bloom’s taxonomy of educational objectives.The effectiveness of the evaluation index system was then validated through the use of quasi-experimental research and survey research,focusing on computational thinking as an example of discipline core competency within the information technology discipline.The specific research activities conducted were as follows:(1)Analyzing the relationship between the core literacy of information technology in junior high school and Bloom’s taxonomy of educational objectives.Further determine the relationship between discipline core literacy and knowledge based on connotation of subject core competencies.An analysis of existing methods for evaluating discipline core competencies revealed a lack of evaluation methods based on knowledge and a lack of process-oriented evaluations.(2)Constructing a core literacy evaluation index system for junior high school Information technology subject based on Bloom’s taxonomy of educational objectives.First,The research builds a framework of evaluation based on the relation between discipline core competence and knowledge,as well as Bloom’s taxonomy of educational objectives.Next,specific content for each evaluation index was determined through a literature review.The Delphi approach was then used to invite experts to score indexes.Based on the feedback and suggestions of the experts,the evaluation indices were revised,and after two rounds of expert consultation,a discipline core competency evaluation index system based on Bloom’s taxonomy of educational objectives was determined.Finally,the AHP was used to determine the weight of the first-level and second-level indices,and each index was divided into five levels of behavior,resulting in the creation of a discipline core competency evaluation scale based on Bloom’s taxonomy of educational objectives.(3)Verify the promoting effect of the evaluation index system for discipline core competencies based on Bloom’s taxonomy of educational objectives theory on computational thinking.Using quasi-experimental research design,a controlled experiment was conducted,with computational thinking in the information technology discipline as the experimental material.A computational thinking measurement questionnaire and two task sheets based on evaluation indexes were designed as research tools to verify the promoting effect of the evaluation index system on computational thinking from different angles.The results showed that based on the analysis of the computational thinking measurement questionnaire,feedback based on the evaluation index system can promote students’ computational thinking improvement,and have different degrees of improvement on students’ problem-solving ability,critical thinking,creative thinking,and algorithmic thinking,Among them,algorithm thinking has been greatly improved.Based on the analysis of the task sheets,feedback based on the evaluation index system can promote the improvement of the five cognitive processes:understanding,application,analysis,evaluation,and creation.However,there was no significant improvement in memory dimension.Based on the analysis of cognitive network,feedback based on the evaluation index system can make students’ answers tend to higher-order cognitive processes.This research explores the core issue of evaluating discipline core competencies.Based on the relationship between discipline core competencies and knowledge and the combination of Bloom’s taxonomy of educational objectives,an evaluation index system is constructed to achieve process-based evaluation of discipline core competencies in the classroom,provide timely feedback on students’ discipline core competency levels,and through quasi-experimental surface evaluation of the application of the evaluation index system,Has a positive impact on improving computational thinking,providing reference for the exploration of discipline core competency evaluation.
