Previous workshop recording and materials 

• Jan 2024 Desmos (with computation layer)

  • activity page with video links 

• Nov 2023 Desmos (basic)

  • activity page with video links

• Sep 29, 2021 (We have tried some GeoGebra Classroom activities)

  • main recording 

  • GeoGebra materials  

  • additional clips about making some of those activities:

    • make a quadratic graph  

    • line and parabola

    • fit a circle 

• Oct 6, 2021 (introduction to Desmos activity) 

  • main recording (due to technical problem, this demo was poorly run)

  • try the sample tasks (more examples in this collection) 

  • additional clips about making some tasks 

    • various graphing tasks 

    • card sort tasks  

• Oct 12, 2021 (graphing activities in GeoGebra) 

  • We tried some simple graphing work while highlighting some unique features in GeoGebra (flexible and dynamic linked representations in geometric and algebraic views). The later part suggested some grahing activities in the context of animation. Modeling can be another good context for developing graphing competence and concepts.

  • main recording 

  • materials from STEM workshop 2018 

    • Halloween animation

  • Mathematical Modeling, Applications with GeoGebra  

• Oct 19, 2021 (Further examples in Desmos activity)

  • We tried some tasks with more advanced setup using computation layer (CL).

  • main recording

  • sample activity in this session  

  • additional clips about making the tasks 

    • using computation layer (CL) 

• Nov 3, 2021 (Unit Circle & Trigonometry) 

  • We studied some examples in GeoGebra and Desmos related to trigonometry and unit circle. 

  • I recommend the teaching strategy explained by W.W. Sawyer. 

  • main recording  

• see the GeoGebra tasks involved (a section about Unit Circle in a GeoGebraBook of Trigonometry) 

• some Desmos activities with similar pedagogical design: 

  • Unit Circle Trig (part 1 and part 2) 

  • some questions based on DSE paper 2  

  • another interesting example of circular stitching in Desmos

• Nov 17, 2021 

  • I talked about finding teaching materials and references online and via ebooks in HKU library (note that current students should have access to the ebooks). 

  • main recording 

  • You can see my collection of resources gathered online in this folder.
