The Effects of STEM Education Through the Creation of Inventions Utilizing Knowledge of Light and Vision to Enhance Scientific Argumentation Skills in Physics 4 of Grade 11 Students at Patthananikom School, Lopburi Province

Abstract

   The objectives of this research were to: 1. develop a STEM Education management plan through the creation of inventions utilizing knowledge of light and vision; 2. investigate students’ scientific argumentation skills, and 3. evaluate students’ satisfaction with STEM Education in Physics 4. The sample consisted of 32 students in Grade 11/2 at Patthananikom School during the first semester of the 2025 academic year, obtained through cluster random sampling with classrooms as the sampling unit. The research instruments included a STEM Education management plan, a scientific argumentation skills assessment, and a satisfaction questionnaire. Data were analyzed using content validity, mean, standard deviation, and the dependent samples t-test.

   The results showed that the STEM Education lesson plans developed through the creation of inventions utilizing knowledge of light and vision comprised 10 lesson plans. The overall appropriateness of the lesson plans was rated at the highest level ( = 4.62, S.D. = 0.37); 2. students’ scientific argumentation skills after the STEM Education were significantly higher than before the learning at the .05 level of statistical significance, and 3. students’ overall satisfaction with the STEM Education, across all seven aspects, was at the highest level.
