IB Math Studies, IB Maths HL I & Algebra ... Student created screencasts

In HS Math, Ange Molony and Lauren Poll asked their students to create screencasts to explain problems and concepts to their peers. The collection of screencasts was posted on the class website as a resource bank for study. Those screencasts were graded based on very detailed rubrics involving expectations around mathematical processes and communication, for example.

In Grade 9 Algebra, students created their screencasts during class choosing among a variety of recording options. As seen on the image to the left, some students used QOMO tablets to help with free hand writing of the formulas. We had 4 tablets available for the class. Other students chose to use the mouse over a PowerPoint where formulas were already typed. These examples and the others mentioned can be seen on the videos below.

In IB Math Studies, students created screencasts over a software emulator for a TI 84 Graphing Calculator. In this case, no free handwriting was necessary which made the recording process easier. The harder work for the students, as reported by Ange Molony, was to break down the problems for explanation. The IB Maths HL I class created the screencasts outside class so they were very creative to get around the free handwriting issue. Below you see an example where a regular video camera was used to record writing the problem over a whiteboard. In the other example the student used an App for the iPad.

The ICT Standards covered by these projects are:
1. Creativity and Innovation: "Students demonstrate creative thinking, construct knowledge, and develop innovative products and processes using technology".
2. Communication and Collaboration: "Students use digital media and environments to communicate and work collaboratively, including at distance, to support individual learning and contribute to the learning of others"
