The research methodology does by research and development in 2 steps as follows: Step 1: The creation and evaluation the efficiency of STEM education learning activities to enhance problem solving thinking ability for Mathayomsuksa 1 students. By creating an activity according to the STEM education model considered the appropriateness of activities by 3 experts and then take to experiment with students who study in Mathayomsuksa 1 at Srithepprachasan school by 3, 9, and 30 students, respectively. The instruments that used for research are the leaning activities, assessment form appropriate of learning activities. The statistics which used for data analysis were Mean (<img title="\bar{x}" src="https://latex.codecogs.com/gif.latex?\bar{x}">) Standard Deviation (S.D.) and E<sub>1</sub>/E<sub>2</sub>. Step 2: The experiment to used learning activities STEM education to compare problem solving thinking ability for Mathayomsuksa 1 students by 41 students. The samples were chosen by Simple Random Sampling. The research design used was One Group Pretest Posttest Only Design and instrument were problem solving thinking ability model measure. The statistics which used for date analysis were Mean (<img title="\bar{x}" src="https://latex.codecogs.com/gif.latex?\bar{x}">), Standard Deviation (S.D.) and t – test (dependent).</p><p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <strong>The result of the research revealed that:</strong> 1) The STEM education learning activities to enhance problem Solving thinking ability for Mathayomsuksa 1 students. It has been submitted for examining the appropriate of learning activities at high level and met the efficiency at 78.49/ 77.98 2) The problem-solving thinking ability in Posttest were higher than Pretest at the statistical significance .01</p> ER -
