The videos in all courses of the HSC project (Algebra 1, Geometry, and Algebra 2/Trig) are produced with Camtasia Studio in .avi format using the TSCC codec, which is optimized for screen-capture videos. Quicktime does not play these videos well. We recommend that you download and use the VLC Media Player (free, open source download) for use with all HSC videos because VLC comes with the TSCC codec. Also, and very importantly, VLC has a very fluent scrolling feature allowing you to move smoothly ahead or back in the videos. This is important for being able to find and review problems.
The spreadsheets used in the HSC courses were constructed with Libre Office (formerly Open Office), a free, open source alternative to Microsoft Office, however, the files are saved in .xls format to be compatible with the Microsoft Office spreadsheet, Excel. There is a Mac version of Libre Office.
Equation Graphing Software
The graphing progeram used in the HSC videos is called Graphmatica, which is a Windows program. However there is a very powerful 2-D and 3-D graphing program that comes bundled with the OS X operating system on the Mac, called Grapher. Grapher can be used on your computer wherever the videos use Graphmatica.
The HSC Geometry course uses pdf files for its Solution Guide. PDF support comes bundled with the operating system on the Mac, so this should not be an issue.
The Geometer’s Sketchpad
The HSC Geometry course uses many demonstrations created with The Geometer’s Sketchpad, which is available from Key Curriculum Press. The Geometer’s Sketchpad disk comes with a Windows and a Mac version on the same disk.
The HSC Precalculus course makes heavy use of the new (and still growing) open source program, Geogebra, which is available for Windows/Mac/Linux at Geogebra.org.
