I. What are Go!Motion and GeoGebra?

Go!Motion

Go!Motion is used to collect the position, velocity and acceleration data of moving objects. Go!Motion connects directly to a computer or Chromebook USB port making it fast and easy to set up experiments and start collecting a wide range of real-time motion data.
Go!Motion can track objects as close fifteen centimeters and as far away as six meters. The sensor also features reduced noise and temperature compensation to ensure accuracy.
  • Analyze the motion of a ball, a cart on a ramp, or a pendulum
  • Adjust sensitivity to track the motion of objects close to Go!Motion or up to six meters away
  • Attach Go!Motion to a track like the one included in the Vernier Dynamics System to study velocity and acceleration

GeoGebra

Often mathematical programs are one dimensional, functioning as a tool for a single subject such as Algebra, Geometry, or Statistics. Two of the most dynamic, intuitive, and useful mathematical tools include Dynamic Geometry Software (DGS) and Computer Algebra Systems. Since there is such a strong relationship between algebra and geometry, students need a program that has both capabilities. Fortunately there is a software system called GeoGebra that integrates possibilities of both dynamic geometry and computer algebra in one program. GeoGebra is a dynamic geometry program that integrates geometry, algebra, statistics, calculus, and more. What sets GeoGebra apart from other mathematical programs, is its dynamic nature. As one plots functions on the coordinate plane, GeoGebra links this with algebra or statistics. Often students overlook the connection between various areas of mathematics, like geometry and algebra. GeoGebra displays the connection in an interactive and intuitive setting. Additionally, data analyzing is possible in GeoGebra. Data can be copied into the spreadsheet function of GeoGebra and then analyzed by students. Thus, for teachers looking for one technology that is free and open source with numerous mathematical capabilities and functionalities, then GeoGebra is the way to go!

II. How can I access Go!Motion and GeoGebra?

Go!Motion

Go!Motions can be purchased for your school here and for Asian providers click here! Logger Lite is a free software that can be used for data collection (in our activity we then transfer that data to GeoGebra). Or you can purchase Logger Pro.

GeoGebra

GeoGebra is a free and open source software that can be accessed worldwide at http://www.geogebra.org. GeoGebra is available on all computer operating systems (Windows, Mac OSX, and Linux), as well as, all tablet operating systems (Windows, iOS, and Android)! Additionally, there is a Google Chrome App that teachers and students can access with Google Chrome. In addition to the main site there is also a subset of GeoGebra, known as GeoGebra Tube (http://tube.geogebra.org) where educators can upload GeoGebra files they have made to share with the rest of the mathematics (or other disciplines) communities! An account is needed for GeoGebra Tube, but it is free and you just need an email.

1. How I Teach Using GeoGebra - Areas and Quadratic Functions - This video is taken from a sequence of videos a teacher put together to discuss Applications of Quadratic Functions. During the first three clips, the teacher sets up a scenario about a picture behind a square piece of matting. She then discusses with her students how they could use GeoGebra to model the scenario. This is the clip of her translating the word problem into a dynamic workspace. The video illustrates how to change the view, define points, create polygons and sliders, and link points with slider values.
2. How to create an interactive java applet - This is a video tutorial showing how to create an interactive java applet (virtual manipulative) using the free program GeoGebra. The author of the video also shows how to export and upload the interactive worksheet from GeoGebra to a web page as a stand-alone and interactive java applet with questions that students can answer by interacting with the content of the worksheet.
3. How to create piece-wise functions in GeoGebra - This video features how teachers can create graphs of piece-wise functions for use in class. The video can very helpful for teachers for creating their own graphs of piece-wise functions for discussing range, domain, modeling situations, and limits in class. The video also illustrates in detail how to rearrange the steps of constructing and/or displaying the graphs and how to make the graphs look clear and accurate.
4. Why Should GeoGebra be used in the Mathematics Classroom? - This video demonstrates the many different features that make the use of GeoGebra necessary in the classroom. Multiple visuals are presented to demonstrate the use of sliders, rulers, and many other functions.
