COMPARISONS OF THE INSTRUCTIONAL MANAGEMENT BETWEEN STEM EDUCATION METHOD AND THE 5E-INQUIRY MODEL FOR DEVELOPING STUDENTS' CREATIVE THINKING ABILITIES AND THEIR ATTITUDES TOWARD PHYSICS ON MOMENTUM AND COLLISION ISSUE OF SECONDARY STUDENTS AT THE 10th GRADE LEVEL IN PHYSICS CLASSES

The purposes of this research were to develop an innovative instructional lesson plan based on the models of learning management in the STEM Education Method and the 5E-Inquiry Model curricula of secondary students at the 10^th grade level on Momentum and Collision Issue in physics classes with the processing and performance resulting effective standardized criteria at the level of 80/80, to compare between students’ learning achievements of their pre and posttests, to evaluate students’ performances of their creative thinking abilities with the instructional designing methods, to assess students’ attitudes toward physics, to associate between students’ learning achievements of their post tests and their creative thinking abilities and their  attitudes toward physics, and to predict the relationships between  students’ performances of their creative thinking abilities and their attitudes toward physics. Administrations with the target sample groups, which consisted of 50 experimental and 46 controlling group students to manage learning activities with the STEM Education Method and the 5E-Inquiry Model from Sarakhampittayakom School, Thailand with the Purposive Random Sampling technique was selected. Using the research type of the Quasi-experimental research was experimented in Two-Group Pretest-Posttest Design.  Students’ learning activities of their processing and performance resulting effective with the innovative instructional lesson plan in 16 periods. Students’ learning achievements were assessed with the 30-item Learning Achievement Test (LAT) with four multiple choices, Students’ responses of their creative thinking abilities were assessed with the 24-item Creative Thinking Ability Test (CTAT) in four scales; students’ attitudes were assessed with a short version of the 8-item Test Of Physics-Related Attitude (TOPRA). Statistically significant were analyzed with average mean score , standard deviation, (S.D.), percentage, independent variable t-test, One-Way ANOVA (eta²), Simple Correlation (r), Standardized Regression Coefficient (β), Multiple Correlation (R), and the Coefficient Predictive Value: (R²)  were used. The results of this research findings: the effectiveness of the innovative learning management lesson plan on Momentum and Collision Issue of the secondary students at the 10^th grade level in the form of STEM Education Method (E1/E2) is 83.70 / 83.47, and based on the 5E-Inquiry Model of (E1 / E2) was 80.00/80.58. Students’ learning achievements of their pretest and post tests for both STEM Education Method and the 5E-Inquiry Model were differentiated (ƿ< 0.001), significantly. The CTAT and the TOPRA by Cronbach alpha coefficient evidence of 0.88 and 0.79 were validated and reliability. Associations between students’ learning achievements of their post-test (PoLAT) and their CTAT, the R² value indicated that 47% and 42% of the variance in students’ creative thinking abilities of their physics classes were attributable to their post learning achievements, students’ learning achievements of  the LAT and their TOPRA toward physics, the R² value indicated that 50% and 36% of the variance in students’ creative thinking abilities of their physics classes were attributable to their PoLAT learning achievements, the coefficient predictive determinant values between students in their CTAT and TOPRA toward physics, the R² value indicated that 67% and 26% of the variance in students’ creative thinking abilities of their physics classes were attributable to their attitudes toward physics in the STEM Education Method and the 5E-Inquiry Model, statistically significant was also found at the 0.01 level,  respectively. In terms of the 5E-Inquiry Model, statistically significant was not found at the 0.05 level between students’ creative thinking abilities and their attitudes toward physics.
