THE DEVELOPMENT OF THE CREATIVITY ASSESSMENT FORM FOR ATTAYOMSUKSA 3 STUDENTS UNDER NONGKHAI SECONDARY EDUCATIONAL SERVICE AREA OFFICE

Abstract

The purposes of this study ware to 1) create the creativity assessment form,                     2) determine the quality of the creativity assessment form, 3) examine the structural elements of the creativity assessment form, 4) determining norms, and 5) create the manual for the creativity assessment form. The sample group in the study was chosen from 600 Mattayomsuksa 3 students studying in the first semester of the academic year 2021 under Nong Khai Secondary Educational Service Area Office by using Multi-stage Random Sampling method. The research tool included the creativity assessment form containing a situational test. The statistical tools used to evaluate the four aspects of quality, including 1) quick thinking, 2) flexible thinking, 3) creative thinking, and  4) thorough thinking. Data analysis employed Construct Validity Index and Discrimination, Power for the construct elements, and Confirmatory Factor Analysis (CFA) for overall validity.

         The results are as follows: The situational test in the creativity assessment form indicated the value of Identification of Concept between 0.60-1.00, with Item Difficulty equaling to 0.420 - 0.769, and Overall Reliability equaling 0.949. The investigation of the structural elements of the mathematical problem solving capability assessment form using Confirmatory Factor Analysis showed the GFI equaling 0.999, the CFI index equaling 1.000, the RMR index equaling 0.003, RMSEA index equaling 0.018, NFI equaling 0.999. The fact that construct reliability equals 0.900 and average variance extracted equals 0.694 proved that the assessment form had construct validity. The norms had normal standard t-score from T₃₄ - T₆₅, with normal standard t-score T₅₀ at the raw score of 75. and get a manual on how to use the creativity measure.
