การจัดการเรียนรู้ออนไลน์โดยใช้เทคนิคการคิดหมวกหกใบ เพื่อส่งเสริมความสามารถในการคิดอย่างมีวิจารณญาณ สำหรับนักศึกษาระดับบัณฑิตศึกษา Online Learning Management Based on Six Thinking Hats Technique to Promote Critical Thinking Ability for Graduate Students

Abstract

         The objectives of this study were to 1) compare the critical thinking ability of graduate students before and after online learning management using the six thinking hats technique, and 2) compare the critical thinking ability of graduate students after online learning management using the six thinking hats technique and a score of 70 percent. Cluster random sampling was used to select 27 graduate students from the Curriculum and Instruction program at the Faculty of Education, Nakhon Sawan Rajabhat University, in the third semester of Academic Year 2021. The research instruments consisted of 1)  the 6 online lesson plans of six thinking hats technique which was at a high level (= 4.80, S.D.= 0.02)  2) critical thinking ability test with a 4 choice option including 30 items with difficulty ranging (p) from 0.25-0.66 a discriminatory ranging (r) from 0.25-0.56 and a precision value of 0.94 The data were analyzed in terms of means, standard deviation and dependent sample t-test and one sample t-test

           The result were as follows:   1) Before online learning management using the six thinking hats technique, the average critical thinking ability score of graduate students was 10.33 with a standard deviation of 3.33. After online learning management, the average critical thinking ability score of graduate students was 23.67 with a standard deviation of 1.94.  Meanwhile, the comparison of critical thinking ability after online learning management by using six thinking hats technique had average score  higher than before management statistical significance at .05 level.

2) The graduate students' critical thinking ability after online learning management using the six thinking hats technique had an average score of 23.67 and a standard deviation of 1.94, which exceeded the criterion of 70% for a full score at the.05 level of statistical significance.
