Based On Top-notch Innovative Talent Training Research On The Construction Of Evaluation Index System Of Middle School Students’ Critical Thinking

The guarantee of high quality development lies in the early training of top-notch innovative talents,and the core lies in developing the scientific literacy of middle school students.Critical thinking is an important component of scientific literacy and one of the important indicators to measure the development level of middle school students’ scientific literacy.Therefore,it is of great significance to construct the evaluation index system of middle school students’ critical thinking based on the cultivation of top-notch innovative talents.The construction of evaluation index system includes two parts: the determination of evaluation index and the development of evaluation tools.Based on this,this study tries to solve two core problems:(1)How to construct the evaluation index of middle school students’ critical thinking based on the cultivation of top-notch innovative talents?(2)How to develop a critical thinking evaluation tool for middle school students based on training top-notch innovative talents?Through combing the research results of top-notch innovative talents and critical thinking,the critical thinking evaluation index of middle school students based on the cultivation of top-notch innovative talents is preliminarily constructed.The final evaluation index is obtained by optimizing the evaluation index through Delphi method consulting expert group opinion.The final evaluation indicators include three first-level indicators: critical thinking tendency(A),critical thinking skills(B),and critical thinking monitoring(C).14 secondary indicators: confidence(A1),perseverance(A2),openness(A3),curiosity(A4),independent thinking(A5),systematism(A6),clarification(B1),analysis(B2),reasoning(B3),evaluation(B4),explanation(B5),summary(B6),self-examination(C1),self-regulation(C2).According to the above evaluation index of critical thinking based on the cultivation of top-notch innovative talents,the corresponding evaluation tool is developed,and the evaluation tool is tested and modified.In order to verify the validity and reliability of the evaluation tool,the validity and reliability analysis were carried out.The validity is analyzed from two perspectives: content validity and structure validity.Content validity was analyzed by calculating content validity index(CVI).The results showed that the I-CVI,S-CVI and S-CVI /UA values of the questionnaire were all greater than 0.83,indicating that the content validity of the questionnaire was good.Structural validity Through the pre-test and post-test survey of two parallel classes,the difference analysis of pre-test and post-test shows that after teaching intervention,the critical thinking development level of students in the experimental group has been improved,while the critical thinking development level of the control group without teaching intervention has no significant change,indicating that the structural validity of the questionnaire is good.Reliability was analyzed by calculating rater consistency and intra-group correlation coefficient(ICC).The results show that the consistency agreement rate of raters is greater than 80%,ICC value is greater than 0.9,the reliability of the questionnaire is good.Through the reliability and validity test of the evaluation tool,it shows that the constructed evaluation tool is effective.
