Abstract
The aims of this research study were 1) to develop activity-based learning conceptual approach with the STEM Education instructional method on the photosynthesis issue to promote students' learning achievements and their systematic thinking abilities at the 11<sup>th</sup> grade level with the efficiency of the processing performances and the performance results (E<sub>1</sub>/E<sub>2</sub>) at the determining criteria as 75/75, 2) to compare between students' learning achievements of their pre-test and post-test assessments with the STEM Education instructional method on the photosynthesis issue, 3) to compare between students' systematic thinking abilities of their pre- and post-learning activities that based on learning conceptual approach with the STEM Education instructional method on the photosynthesis issue, 4) to analyze of students' associations between their learning achievements and their systematic thinking abilities with the post learning activities that based on learning conceptual approach with the STEM Education instructional method on the photosynthesis issue. Data administrations with a sample size consisted of 21 upper secondary educational students at the 11<sup>th</sup> grade level from Mahawichanukul School under the Maha Sarakham Secondary Educational Service Area Office 26 with the purposive sampling random technique was selected. The research instruments were determined with a main-STEM Education instructional method's lesson plan to management of the activity-based learning conceptual approach in 15 hours, the <em>Learning Achievement Assessing Test</em>, and the <em>Systematic Thinking Ability Measuring Test</em> were used. Statistically significant with the average mean score, standard deviation, percentage, independent variable <em>t</em>-test were analyzed, simple and multiple correlations, standardized regression weight validity, and coefficient predictive value (<em>R<sup>2</sup></em>) were associated.
The results of these research findings have revealed as:
