Exploring Customisable Math Apps



Date and Time

25 Jan, 22 Mar, 3 May
1430 - 1730 hours
Mr Lawrence Wee Loo Kang 


Learn how customisable Math Apps can engage students in activities to explore and learn mathematical concepts and skills in a fun way.
Participants will learn how Math Apps can be used in activity-based learning.

Content Outline

By the end of the session, the participants should be able to
1. Use the Math Apps to help students uncover abstract mathematical concepts or results
2. Customize Math Apps to meet students’ learning needs



Looking for interesting ideas to help your students explore and learn mathematical concepts and skills in a fun way? The Math Apps allow students to experiment, explore and construct meanings and understandings between concrete and abstract mathematical ideas. The workshop facilitators will also share their experiences using Math Apps for teaching & learning and how to customize the Math Apps to suit your students’ learning needs.

Workshop Flow

10 mins introduce Math LC,  community  overview (CH and HM), tools (geogebra, maps etc)

ICT1 Use of EJSS simulations to teach Oscillations by Kwek Eng Yeow (VJC)

Pedagogy (Misconceptions, Assessment, etc.)

I have used the EJSS simulations created by MOE ETD-CPDD and myself to illustrate concepts in Simple Harmonic Motion (SHM) during my lecture in August 2016. I use a traditional lecture method of teaching, while using the simulations for the following purposes: • Explain basic terms used in SHM.
• Illustration of forces present in spring-mass system.
• Illustrate relationship between circular motion and SHM.
• Illustrate the Phase relationship between 2 identical systems undergoing SHM.
• Visualization of SHM for basic calculations in a worked example.
• Visualization of particle velocity and displacement in SHM for worked example.
• Visualization to explain the concept of phase angle in SHM.
• Visualization to show the relationship between the acceleration-displacement graph and the actual SHM.
• Using the velocity-time graph and simulation of SHM to explain the variation of KE with time and position.

ICT2 Modelling-Inquiry Enabled Interactive Textbook – Gravity and SHM by Lim Ai Phing (RVHS)

We are a team of physics teachers, from various pre university institutions, Curriculum Planning and Development Division (CPDD) and Educational Technological Division (ETD), working to empower students to learn difficult physics concepts in topics such as Gravitational Fields and Simple Harmonic Motion (SHM) via inquiry learning, specifically through the use of mathematical modelling. Past observations suggest that current lecture notes are non-interactive (no input for mathematical algorithm outputs), and thus learning difficulty may stem from lack of integrating mathematics with physics as well as the availability of computer simulations which allow input of mathematical models. Thus, our team is formed under an eduLab project ( which seeks to create an interactive textbook-chapters with (re-created +30 related oscillator and gravitation models) to conduct inquiry experiments and (newer) mathematical modeling practice on simulated data, enabling mathematical-modeling learning for A level Physics students. We will be focusing on Gravity and SHM ebooks for this paper.

On behalf of the Physics IPSG (“Instructional Programme Support Group”) committee, we’d like to invite you attend the 9th IPSG sharing session for the A-level Physics educators. This platform provides an opportunity for us to gather as a community to share our experiences and good practices with regards to physics education. The event will be held on 18 Jan 2017 (Wed) from 2:30 pm – 5:30 pm at Jurong Junior College (JJC):


If you are interested in attending, please sign up for the IPSG through the link:  [Please do so by 6 Jan latest as we will be arranging catering.]

The theme for 2017 is “Practices of Science in the Physics Curriculum”. We hope to use this lens to focus on the variety of ways that schools have implemented the revised H2 Physics curriculum.

More details on the IPSG, including the detailed schedule, abstracts of the poster presentations and seminar presentations can be found on our official IPSG blog:
Please prepare your poster for the gallery walk, and send us a high-resolution PDF copy of the A1-size poster by 6 Jan. We will batch all posters for printing

We look forward to seeing you! (Please feel free to forward this to any colleagues you think might be interested!)

Nature of Science Tracker Water Rocket Model

i have added a model which i feel has alot of power for learning, even though it is flawed.


fy = -9.81+if (t<0.5,T,0)

where T is 23.4 N.
what the model suggests is the thrust is 23.4 acting for 0.5 seconds at beginning of video.


mass is constant
thrust is constant at 23.4N

my observation

the flight path is roughly close the real motion.


of course the model is flawed, but that is the nature of science, better model gets made by building on other people's idea.


can you build a better model ?
