The purpose of the study was to develop the Arduino based STEAM instruction materials for creative engineering design class. PDIEmodel was used in this study. We developed a STEAM lesson plan and a STEAM lesson worksheet for a total of six sessions throughthe steps of preparation, development, implementation and evaluation. The validity of the instruction materials was evaluated by the10 experts using a survey. The instruction materials were applied to the class (52 students attended) of the creative engineering designsunit in technology and home economics subject. The class satisfaction and the creative solving-problem ability were examined afterthe calss. The class satafacition was high as the average of 10 item was 4.57 (out of 5). The paired t-test was conducted to comparethe means of the creative solving-problem ability. It was observed that ‘understanding and mastery of knowledge, thought, functionand skills in a specific domain', ‘divergent thinking', ‘critical and logical thinking' and ' motivational factors' were significantly increasedafter the class. The instruction materials develped in this study were successfully designed to enhance the creative solving-problemability by designing creative tasks and to intrique the interest by adding visual and auditory stimuli with the Arduino.
