There are two recent updates in GeoGebra, the first one is the GeoGebra Exam Mode and the second is the GeoGebra Followers feature for its website users.
GeoGebra Exam Mode
One of the recent developments in GeoGebra is the GeoGebra Exam Mode. In this mode, students can use GeoGebra while taking exams. If a student leaves the the GeoGebra window, the GeoGebra toolbar will turn red (see below) and logs the time and duration the student left the window, so teachers would know if students used other programs.
You can access the GeoGebra exam mode here. It runs in major browsers (Chrome, Firefox, Internet Explorer 11, Safari). It also runs in full screen, so students cannot use any other program while using it. Further, it can be customized allowing access to selected features (e.g. you can disable the CAS window). » Read more
In the previous post, I have shared to you the advantages of using Wolfram Alpha. In this post, I am going to list some of the basic calculations that can be done using the same app. Note that you can use these commands both in the iOS version or the web version.
1. Do Basic Arithmetic with Integers, Fractions, and Decimals
150 + 32
1200 – 3
15.8 * 2.5
1/5*(3 – 8)
2. Compute Decimal Approximation to a Specified Number of Digits
pi to 1000 digits
e to 50 digits » Read more
It’s been a while since I have written about GeoGebra, but I have started updating some of the tutorials to GeoGebra 5. For those who have not explored the Archives, I have written numerous GeoGebra tutorials ranging from basics to advanced.
GeoGebra is now version 5.0. New features were added and a lot of improvements had been made. The 3D is now stable and 4 new tools were added. The Insert Image tool now support SVG files. But aside from these, there are simple updates which I really like and I think teachers will also love them. Here are four of them.
1.) Automatic Color Change
Every time you graph a new function in the current version of GeoGebra, it automatically selects a different color. You don’t have to trouble yourself changing the color of the graph of the new functions. » Read more
