This article outlined a module in which students solved real-world problems through technology-rich, engineering design activities that integrate both mathematics and science. The module consisted of 5 components that start with "E" as listed.

How can we improve the performance of the soap derby car (any mini car)?

Here, they defined specifications and constraints.]]> 2021-05-04 03:36:45 UTC https://padlet.com/hyunjilee9/wq4h33tvckrlza30/wish/1488083810 Exploration hyunjilee9 https://padlet.com/hyunjilee9/wq4h33tvckrlza30/wish/1488089157 In this phase, students explore  how the different body shapes of the car affected its speed and performance, based on what they know about force and motion.

Students were giving lab materials and wrote down their observations.]]> 2021-05-04 03:39:49 UTC https://padlet.com/hyunjilee9/wq4h33tvckrlza30/wish/1488089157 Explanation hyunjilee9 https://padlet.com/hyunjilee9/wq4h33tvckrlza30/wish/1488098346 Once students found that rounded shapes performed better overall than box-like shapes, they were asked to explain why they thought that was the case.

This was discussion based, leading into the aerodynamics topic as well.]]> 2021-05-04 03:44:50 UTC https://padlet.com/hyunjilee9/wq4h33tvckrlza30/wish/1488098346 Extension hyunjilee9 https://padlet.com/hyunjilee9/wq4h33tvckrlza30/wish/1488101130 After exploring different shapes, students were then prompted to improve the shape of the soap derby car. Students brainstormed using CAD design, which was then fabricated using 3-D printers.]]> 2021-05-04 03:46:31 UTC https://padlet.com/hyunjilee9/wq4h33tvckrlza30/wish/1488101130 Evaluation hyunjilee9 https://padlet.com/hyunjilee9/wq4h33tvckrlza30/wish/1488106702 Throughout the activity, students had formative assessments in the form of reflection questions. They also had a summative assessment that asked them to reflect on the process and write down what they learned.]]> 2021-05-04 03:50:20 UTC https://padlet.com/hyunjilee9/wq4h33tvckrlza30/wish/1488106702 How I will Use this in my Own Classroom hyunjilee9 https://padlet.com/hyunjilee9/wq4h33tvckrlza30/wish/1488116792 I think these 5 components of computer-aided design for problem solving flow very nicely, and would like to incorporate it into my classroom.

In Geometry, we are working on using algebra to prove geometric theorems. More specifically, we are distance formula to classify triangles. We are also proving how/why certain points of a triangle lie on, outside, or inside a circle. 

I could start off by presenting a video to grab their attention. A potential real-life problem could be that we are launching a rocket into the air and in order for it launch straight upward, we must find the center of the circle and measure the distances to ensure maximum speed.

I would have them explore what works best, design their rocket on a software, perhaps have them print it if we had access to 3D printers, and of course provide extension and evaluation questions.]]> 2021-05-04 03:57:36 UTC https://padlet.com/hyunjilee9/wq4h33tvckrlza30/wish/1488116792 Critiques hyunjilee9 https://padlet.com/hyunjilee9/wq4h33tvckrlza30/wish/1488136505 Something I would want teachers to consider before implementing the evidence-based practice is student biases. This activity is very technology heavy, and includes softwares that may not be easily accessible to all students. Furthermore, expensive equipment such as 3-D printers may only be accessible to more affluent schools. 

Furthermore, too much technology at once can be overwhelming to the students. I think it is important that we establish a stable platform where all students can access materials and then slowly incorporate the technology that enhances learning so that students have an overall meaningful experience.]]> 2021-05-04 04:09:14 UTC https://padlet.com/hyunjilee9/wq4h33tvckrlza30/wish/1488136505
