Comparisons between Teaching Effectiveness according to the Guidelines of the STEM Education and Conventional Learning Methods on Electrochemistry Issue of Secondary Students at the 11th Grade Level

Abstract

The aims of this research study were to create the instructional lesson plan with the STEM education instructional method on Electrochemistry Issue of secondary students at the 11^th grade level in two groups that consisted of 43-conventional students’ learning controlling group and 44-STEM education’s learning experimental group from Sarakhampittayakom School under the Secondary Educational Service Area Office 26 with the Random  Assignment Sampling technique was selected with the efficiency of the processing performances and the performance results (E₁/E₂) at the determining criteria as 75/75 to promote students’ learning achievements of their the STEM education method (STEME) and their Conventional Learning Method  (CLM).  Students’ learning achievements of their post-test learning outcomes to their STEME and CLM were compared, students’ responses of their science process skills with the STEME and CLM were created, students’ solving problem abilities of their post learning outcomes with the STEME and CLM were assessed, and to associate between students’ learning achievements of their science process skills to their solving-problems thinking abilities on electrochemistry issue were analyzed. Using the instructional design model with the STEME and CLM innovative lesson plans were administered, students’ learning achievements were assessed with the 40-item Learning Achievement Test (LAT), students’ perceptions of their scientific process skills with the 20-item Scientific Process Skill Test (SPST), and their solving problem abilities were assessed with the 36-item Solving Problem Ability Assessment (SPAA). The results of these research findings have revealed as: students were evaluated to determine performance criteria with the efficiency of the processing performance and the performance results (E₁/E₂) of 77.24/75.18 for the STEME innovation lesson plans, which was higher than standardized criteria of 75/75. Students’ learning achievements of their STEME and CLM assessing differences were also found evidence at the 0.001 level, significantly. Students’ responses of their scientific process skills of their STEME and CLM were differentiated evidence at the 0.001 level, significantly. Associations between students’ learning achievements and their scientific process skills, the coefficient predictive values (R²) indicated that 37% and 56% of the variance in scientific process skills for the CLM and the STEME, students’ learning achievements and their solving problem abilities, the coefficient predictive values (R²) indicated that 53% and 76% of the variance in solving problem abilities for the CLM and the STEME, and students’ solving problem abilities and their scientific process skills, the coefficient predictive values (R²) indicated that 46% and 72% of the variance in scientific process skills for the CLM and the STEME, respectively. Suggestions that STEM degree holders have a higher income create critical thinkers, increases science literacy, and enables, which students of innovators. Innovation leads to new products and processes.
