Based on results of a 2018 Iowa Science Teacher Section survey, the Iowa Science Foundation of the Iowa Academy of Science funded a professional development opportunity focused on engineering design (ISF 19–01). A free one–day workshop was created for school districts in Iowa, and the first was held in fall of 2019. During this workshop, teachers learned more about engineering design, experienced engineering design activities from kindergarten through high school levels, and brainstormed facets of engineering design. The day ended with guiding teachers in writing their own engineering design activities. The workshop was successful and well–received according to a post–workshop survey using a five–point rating scale. Comments included “I have a better understanding of how to use engineering design in my classroom” (4.56/5.00), “I was able to make good progress in developing an engineering design activity” (4.67/5.00), and “I would recommend this workshop to friends and colleagues” (4.78/5.00. Participating teachers learned skills that will impact more than 1,100 students, and additional workshops continue to be scheduled.
