At the beginning of this project we initially planned on having students use software to design a bridge to be printed with a 3D printer. Within a few planning sessions we began to realize that we had maybe jumped a few steps and we were feeling overwhelmed with the task. We felt as a team that we needed to step back and look at our teaching of the Structures Unit first. How could we motivate and teach the unit with more hands on engaging activities? From there we began thinking more about the big ideas in teaching and learning and factors that motivate students. From reading different articles and conversing with STEM-TIA facilitators, we began rethinking our ideas. We read an article about The EDP- 5E: A rethinking of the 5E replaces exploration with engineering design and began focusing our attention on implementing such challenges with students. We felt in order to increase student motivation and to get students excited about learning science, we needed to get students more involved in their learning. The article referenced a website “Engineering is Elementary” that was very useful in helping us understand the Engineering Design Process and how to implement it with our students. Once our decision to use the engineering design process was made, we then began reading articles about design challenge lessons. Our STEM-TIA facilitator was very good at getting us involved in the design challenges as well so that we could build and experience the success and failure as our students would. We also spent time looking for children's literature to complement the unit and to help the students understand the engineering design process and that it is alright to make mistakes. The engineering design process would require them to improve and rebuild.
