Development of stem activities for high school physics classes

Kartal, Nurgün
The purpose of this study is to develop STEM Engineering Design Process (STEM-EDP) activities for 10th and above grade levels by using an ADDIE instructional design model.When the literature wasreviewed in detail, it was very rareSTEM-EDPactivities which are developed based on systematic models. Therefore, the characteristics of STEM activities were formed bythe basis of ADDIE model. Also, for the implementation processes of the STEM activities, 7-step EDP modelwas used. As a result, 3 STEM-EDP activities were developed in this studywhich areearthquake resistant concrete building design, earthquake resistant wooden building design, and technologies design to prevent buildings from earthquake.Design Based Research (DBR) method was used for the purposeof developing STEM activities since it is a systematic and flexible methodology. Three physics teachers and 18 students were included inthe activities. The studentsare 10thgrade taken from an Anatolian high school and the physics teachers have one to three years of experience.A physics teacher, who is called aninstructor, hasapplied activities to the studentsand the researcher has applied activities to the three physics teachers atdifferent times. During each activity, the students are placed to heterogeneous groups with 6memberswith 2 low, 2 medium and 2 high achievement levels.Implementation of ithe first activity has passed 1200 minutes in 14 days,the secondactivity has passed 670minutes in 11 days and the thirdactivity has passed 460 minutes in 8 days. Semi structured interviews forthe students, the teachers and the instructor,the researcher’sobservation notes,and observation formfor the instructorwere used as data collection tools.As a result of the analysis, the STEM activities were revised and improved.
