Week 3 - 13 October

Online Lesson Takeaways

  1. Laser Cutting

Assignments

Task 1: [RulCompass]

  • Design and cut with the laser cutter product that I have invented to combine the use of ruler with compass. Hence students will not need to buy a specialised tool - compass for $2 - $6 just for use within a S2 mathematical topic of Geometrical Construction. This object can be used to solve any Geometrical construction question from Sec 1 Mathematics Syllabus to O level Syllabus in Sec 4. In other times, it can be used as a normal rule as as well to draw circles of diameter 1cm, 1.1cm 1.2cm, … to 15.7cm, 15.8cm, 15.9cm and 16cm.

Process

Design Process

  • Use of pythagoras to calculate the (x,y) coordinate of each circle of the 150 circles for the drawing of the circles of various dimension from 1cm to 15cm.
  • Use of excel to calculate the position of each circle.
  • Use inkscape for the design and corel draw in the DFC for the laser cutting.

Task 2: [Paint a laser cut tissue box]

Think on one or two educational activities in which you could integrate the laser cutter at some stage of the activity. Explain briefly the activity. Do not forget to clearly indicate the learning objectives.

Task 3: [Reflection]

Reflect on your own practice. When you prepare a lesson activity what are the things that you take into consideration? What are the critical aspects? What additional aspects do you need to take into consideration if you utilize digital fabrication processes? Reflect on your past educational activities. How have you considered Socio-Emotional learning (or soft-skills) when preparing the activities? Could you provide some concrete examples? How have you changed your perspective on socio-emotional learning / soft-skill / horizontal competences after this lecture

Reflection

- Key learnings

  1. I picked up numerous skills during the design phase. Thankful for the DFC team Seh Yong and Jonathan for their valuable support and the loan of laser cutter to cut out the prototype.

  2. There are always very good feedback from the users that will require you to put in the time and space to improve on your prototype.

- Next steps or improvements

Feedback given by users are used to improve on the product design.
