The aim of this study was to find out the effect of instruction with storytelling on the achievement, attitude and interest in science. For this study, two classes were divided into experimental class and comparative class. All the results were analyzed quantitatively. Results of this study can be described as follows. First, the experimental class didn't have a significant difference in scholastic achievement compared with the comparative class. However, the results of the t-test for the academic achievement due to achievement level showed a positive effect in the average level of students. And experimental group was statistically significantly higher in the section of 'Combustion and Extinguishment' than that of the other group. Second, There was a significant difference in the aspect of the effect of instruction with storytelling on the student's science-related attitudes. As a result of analysis by sub categories of science-related attitudes, storytelling was effective in attitude toward science, but no significant differences were found in scientific attitude. Third, instruction with storytelling didn't show a meaningful difference in scientific interest. However, in the sub-part, they showed a meaningful improvement in attention and satisfaction.

The purpose of the study was to develop the Arduino based STEAM instruction materials for creative engineering design class. PDIE model was used in this study. We developed a STEAM lesson plan and a STEAM lesson worksheet for a total of six sessions through the steps of preparation, development, implementation and evaluation. The validity of the instruction materials was evaluated by the 10 experts using a survey. The instruction materials were applied to the class (52 students attended) of the creative engineering designs unit in technology and home economics subject. The class satisfaction and the creative solving-problem ability were examined after the 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 compare the means of the creative solving-problem ability. It was observed that 'understanding and mastery of knowledge, thought, function and skills in a specific domain', 'divergent thinking', 'critical and logical thinking' and ' motivational factors' were significantly increased after the class. The instruction materials develped in this study were successfully designed to enhance the creative solving-problem ability by designing creative tasks and to intrique the interest by adding visual and auditory stimuli with the Arduino.
