On the Job Training: Using GeoGebra in Teaching Math

For the last several years, our Institute has been accepting on the job trainees from nearby universities. These trainees are undergraduate students taking up bachelor’s degree in education. As for our group, we are accepting students who are taking education major in mathematics.

This year, we have accepted two students who are on their third year of university studies. I have been handling them already for three weeks of their 6-week course. In this post and the next several posts, I will be sharing our activities during the training.

During our first meeting, the two students shared that they wanted to deepen their understanding on content and strategies in teaching mathematics. Since my specialization is on the use of technology, I have designed their training with the focus of integrating technology in teaching mathematics. This includes familiarization with various theoretical frameworks used in teaching mathematics using technology, using a software in creating teaching and learning materials, and developing lessons with technology integration. Once a week, we also discuss key content topics in high school mathematics and various ways to teach them.

At the end of the training, the students are expected to develop applets and lessons using GeoGebra. They will implement the lessons with me and my colleagues as audience. After the implementation of the lesson, we will comment on how the lessons can be improved.  Their last task is to revise the lesson. Their major output is a lesson plan.

For those who are not familiar with GeoGebra, it is free software that can be used for teaching and learning mathematics. You can download it here and there are various tutorials on learning the software here. GeoGebra is available on Windows, Mac, Linux, iOS and Android operating systems.  You can use it on laptops, tablets, and mobile phones.

GeoGebra Graphing Calculator for Android now available

For GeoGebra fans who are Android users, the long wait is over. GeoGebra has just released the new GeoGebra Graphing Calculator for Android phones and tablets. According to GeoGebra’s official blog, this new version has Algebra and Graphics views, but more features will be added soon. They are also planning to release iPhone and Windows versions later.

I have downloaded this app and the first feature I looked for was a slider, and so far, it’s working just like the the PC version. Just like in the PC versions, you can also use the materials uploaded in GeoGebraTube» Read more

  • GeoGebra Sign-in option to let you stay Signed in while working
  • Larger Check box, Command button, and Slider
  • Export to HTML was replaced with Upload to GeoGebraTube (Press Ctrl-Shirt-M to explore Java/HTML5 to clipboard)
  • New Filling styles

For those who have not tried using GeoGebra, it’s an amazing software for teaching and learning mathematics. You can visit the official GeoGebra website to know more about it and download the software for free.  If you want to learn using it, I have written more than 50 tutorials about it.
