Week 8

Assignments

  • [ ] Task 1:For this Field Activity, you will design (or adapt) test and reflect on a lesson plan for a subject you teach. Your lesson plan must include electronics components and/or basic programming elements.
  • [ ] Task 2:This time you can adapt or reuse one of the lesson plans available (see below). It is important that you adapt the lesson plan to your own context, modifying if needed the learning goals.

Process

Steps: * What is Printed Circuit Board?

  • Five steps of stitching circuit

  • Short introduction of Arduino

  • Make it shine

  • Review the lesson from Circuit Diagram

  • Challenges and solutions When explaining the entire course, many details are not clear enough. The students’ scientific and technological innovation skills vary greatly. Therefore, while introducing the course framework, it is also necessary to carefully explain the uses of materials and the working principles of circuits. Only in this way can students successfully operate their own sensors and make correct connections when they come into contact with them for the first time. If students do not clarify the connection of the positive and negative poles on the fabric at the beginning, it is easy to find a short circuit after sewing for a long time, and then everyone will be very frustrated and unwilling to start over.

Reflection

  • Key learnings Through this course, students will learn the complete process of circuit board design and fabrication, and realize simple wearable functions by sewing the circuit boards onto clothing.

  • How it applies to your teaching / context First, there is the concept of a wearable T-shirt, followed by the development of a course plan. The plan ranges from using an app to design a simple circuit diagram and programming to realize the color and pause time of LED lights, to incorporating the idea of enabling up to 8 sensors to work together. In class, students are guided to practice hands-on: they thread needles and sew small modules onto the fabric, ensuring the positive electrodes align with positive electrodes and negative electrodes with negative electrodes.

  • Next steps or improvements Short circuits are likely to occur during the sewing process, so some tools are needed to assist students in completing the project. Since the process is also relatively time-consuming, students can start by implementing the wearable function with 3 sensors. Those who have extra capacity can increase the number of sensors to finish their works within the limited class time.Make sure the course is both flexible and challenging.
