Software Learning Kit for Mentally Retarded Children Using Java
Workshop 2.0
Software Project 1: Learn to Identify Animals and their Sound
Working platform: Windows 95/98
Objectives: To identify the shape of different animals and their sound.
Optional Features: If possible, all instructions in the kit should be in Chinese or
Cantonese.
Part I – Program Design
By using Java Workshop 2.0, design a standalone Java program that performs the tasks as specified
below:

Exercise Phase
1. For every exercise below, the performance of student should be logged in a file and shown when user
presses the Result button on the Startup screen.
2. For each screen, there should be buttons that allow user to go from one exercise to another or back to
the startup page.

Part II – Report
Write a report of not less than 5 pages (excluding program codes) to describe how you write this program.
Detail describe all techniques you use, any technical problems you encounter and any solutions you use to
solve these problems. Describe your program using flow charts with verbal explanations. Attach your
program as an appendix at the end of your report.
General Description
a. Each group should normally comprise 3 students. Each group should hand in
i) both soft and hard copies of the report
ii) a soft copy of the program
on or before 12 May 2000. A demonstration of the program to your classmate should be made on
either one of the following dates: 16 May or 19 May.
b. It is very much preferred to use a word processing package to type your report. The contents of the
report are most important. However, you should try your best to write clear, correct and good
sentences.
c. Distribution of marks: Program design 65%
Report writing 35%
d. The specification above only defines the fundamental requirements. You may add your own ideas to
the program. But remember, your target is a group of mentally retarded children. Most of the
programs require a certain amount of multimedia materials, such as, graphics, sound, animation, etc.
You need to find your own way to get these materials (Try to search on the Internet before you give
up).
e. There should be a clear and even allocation of tasks among group members. Each member will be
individually assessed. Group member with larger contribution to the project will acquire higher
marks. The task allocation strategy among group members should be clearly described in the report.
f. A prize will be given to the best project. Upon evaluation or modification, the program will be
donated to a school for mentally retarded children.
