The purpose of this research is to propose an instructional model based on Science, Technology, Engineering, and Math (STEM) Education approach for enhancing the information and communication technology skills for elementary students in Thailand. The study was conducted by research and development design and divided into two phases: Phase I is to create a tentative model that was synthesized using the relevant documents and researches concerning the elements and steps of the model. The data was collected through interviewing eight teachers who are experts in STEM education and twenty-four students who were instructed by STEM approach. Phase II consists of proposing a tentative model to eleven experts, evaluating the model, and acquiring an approval of the model by five professionals. The findings of the research are as follows: 1) This model consists of five main elements–principles, purpose, content, teaching and learning process and measurement and evaluation of ICT skills. There are six steps from the engineering design process consisting of problem identification, related information search, solution design, planning and development, testing evaluation, and design improvement and presentation. 2) The eleven experts evaluated the tentative model as appropriate at a high level. The five professionals approved this model as appropriate at a high level.
