The aims of this research were to develop an innovative instructional lesson plan based on the model of the STEM Education instructional designing model (STEM Model) with the effectiveness of processing and performance resulting outcomes to be effective (E1/E2) according to the criteria level of 70/70, to compare between students’ academic achievements of their pretest and posttest assessments with the STEM Model, to compare between students’ academic achievement of their posttest assessment and their standardized criterion of 70% threshold, to assess students’ perceptions of their attitudes toward science after the STEM Model were administered, and to analyze the associations between students’ academic achievements and their attitudes toward science after the STEM Model were administered, completely. The sample target group consisted of 22 secondary students at the 11th grade level in chemistry class from Mahawichanukul School under the Maha Sarakham Secondary Educational Service Are Less
