• Button Sorting is a HyperCard stack that demonstrates visually the action of a number of different sorting algorithms. It requires Hypercard 2.3 or HyperCard 2.3 player. For those with knowledge of HyperTalk scripting it should not be too difficult to modify the stack for HyperCard 2.2 (delete any scripts that begin "speak..." - mainly on the card level). This stack is freely available for educational uses but must not be sold for profit. Download Button Sorting. (8K)

• Sorting Exercises is a HyperCard stack that sorts a list of random numbers into ascending or descending order using a variety of algorithms. It requires Hypercard 2.1 or HyperCard player. This stack is freely available for educational uses but must not be sold for profit. Download Sorting Exercise. (8K)

1. Plot a quadratic equation and zoom in on the roots
2. Allocate grades to students depending on their marks using a lookup function
3. Scale marks to a new mean and standard deviation
4. Use recursion to work out a bonus (an example of a circular reference)
The file includes documentation. To work the spreadsheets you need to deselect "formulas" in the display dialog box of the options menu. This document was originally prepared in written form as a contribution to the Computing Studies Teachers Association Journal This electronic version is freely available for educational uses. It can probably be easily converted to work on Windoze machines. Download Spreadsheet Examples. (13K)

• Multimedia On The Mac is a MS Word 5 file that was originally published in the CSTA journal during 1996. It includes a discussion on using ClarisWorks and Netscape for multimedia projects. The main focus is on the use of HyperCard. Example scripts to be used with navigation, hypertext, sound etc are given. Download Multimedia On The Mac. (13K). Another more recent version (1997) can be downloaded here(37K). It includes a lot more information on using html and Netscape for multimedia development.

• HSC Scaling is a ClarisWorks 2.1 spreadsheet that allows for a comparison to be made on the relative scaling of popular HSC subjects. Board marks obtained by students can be entered for each subject and the likely scaled mark used for TER calculation purposes is obtained. This spreadsheet uses data from Professor Cooney's report to Principals (table1) on the 1995 HSC. This data was curve fitted using polynomial equations (usually of order 4) to obtain TER scaled marks. Using this we can see, for example, that a board average weighted mark of 60% in 2 unit (common) Computing Studies scales to about 42 whilst the same mark in 2 unit Business Studies scales to 40. The method used in this spreadsheet is not similar in any way to the Universities method of scaling - it is merely an attempt to show students (and me) crudely how subjects compare. This spreadsheet is freely available for educational uses. It can probably be easily converted to work on Windoze machines. Download HSC Scaling. (11K)
