GeoGebra has improved a lot since I was first acquainted with it in 2006. For the subscribers of this blog, you have probably come across my series of tutorials on how to use the app. In recent years, GeoGebra has evolved into several apps that can be used for specific tasks. It has also become compatible with major operating systems including Windows, Mac, Linux, iOS, and Android. The different GeoGebra apps are the following:
The Classic has two versions and is the most comprehensive among the apps. The 3D app has also support from Augmented Reality. In addition, one of the recent updates of GeoGebra is its support for examinations.
My Current Work on GeoGebra
Personally, I have been involved in developing applets and lessons for the GeoGebra Institute in my country (see example below). You can view my applets at the official GeoGebra website and some short videos demonstrating the capabilities of GeoGebra at our GeoGebra Institute Facebook page. The official website of our GeoGebra Institute is currently being updated here and hopefully, we can upload lessons that are readily available for teachers soon.
At the Institute where I work, we have also integrated GeoGebra in several of our teacher trainings. Last year, we have obtained funding to train potential trainers. The project includes developing a module for future trainers and a 2-phase training. The training was supposed to be start in April but was postponed due to the current pandemic.
Some Resource on GeoGebra
There are so many tutorials if you want to learn GeoGebra. You can see my tutorials here or read the GeoGebra Manual. As for the applets, there are millions of applets uploaded in the GeoGebra website. Some of the excellent GeoGebraists are Daniel Mentrard, Tim Bzherzhinski. The GeoGebra Institute of Bogota is also very active.
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.
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
