Lab 1: Tour of a Computer: "What's Inside the box?"

Objectives: 1) To see the components of a computer

2) To learn some of the terminology

3) To feel more comfortable using a computer

Method: 1) View a video on computers

This video will give a quick introduction to the inner workings of a computer system.

2) Identify major components of the computer system.

All of the computers in LH2 have a monitor, keyboard, mouse, "computer", a hard disk drives and either one or two "floppy" disk drives. All of the computers are also linked via a printer-switchbox to a printer.

CPU, RAM, ROM, KB, MB, bit byte

Lab 10: Developing a Presentation using the Authorware Working Model

GENERAL NOTES

Authoring software is used for developing multimedia presentations and interactive learning. Authoring software can be used to design computer-based courseware for education and training, sales presentations at kiosks in shopping centers, demonstrations or simulations of products being sold and in interactive magazines.

The Authorware Working Model will allow you to develop a simple presentation that includes sound, graphics and video animation. This will be accomplished by dragging and dropping icons that represent the different parts of your presentation. These different icons each represent programs that can be included in your presentation.

OBJECTIVE: To learn how to design a presentation using a computer and the Authorware Working Model software.

Method:

1. Run the Windows program and select the Authorware Working Model icon.

2. Run the Welcome file: (15 minutes)

a) double-click the WELCOME.APW icon.

b) choose Run from the Try It menu at the top of the window.

c) at any time during this open presentation, you can stop the program and switch to the file design window to see how the presentation was built (This is done by choosing Jump to Icons from the Try It menu). Return to the presentation by choosing Jump to Display from the same Try It menu.

d) As you look at the the way the presentation is designed, you should notice:

i) A flowline shows the structure of the presentation.

ii) The presentation includes an Intro sequence icon. If you double-click on this icon, you will see that it expands into a collection of other icons which make up the Intro sequence.

iii) The Main Menu interaction icon contains a collection of choices for the user to select from. These options are represented by icons here, but when the presentation is run, the options are displayed in a dialog box for the user to select an option.

iv) If you look in the Welcome.apl window, you will see some of the Authorware library of graphics and sound files. These can be selected for use in your presentation.

3. Designing a simple presentation on Coffee. (30 minutes)

a. CREATE A FILE

i. Open the COFFEE.APW file located in the AP_MODEL\EXAMPLES directory.

Your presentation should include animation, movies and sound as well as an interaction. You will find pictures in the images.apl directory, sounds in the sounds.apl directory and movies in the movie.apl directory. Have fun.

Lab 11: Introduction to Programming using Karel the Robot

"We believe that most people will not actually have to program a computer as part of their everyday lives, either now or in the future. However, many people will need to be able to use a computer and will occasionally need to do something with the machine beyond the 'ordinary.' Simply put, they will have to solve some type of computer problem." Pattis, Richard E., Karel the Robot, John Wiley & Sons, Inc., 1995, p. vii. Karel will improve your problem-solving skills using a computer. Karel will also provide you with an insight into what computer programming is about.

Objectives: 1) To become comfortable with the Karel Environment.

2) To write a simple Karel the Robot program.

Method:

1) Read the attached pages 1-24 of the KAREL Users' Manual.

2) Run the Simulator. Use

STAIR.KRL for the program

STAIR.ANN for the annotated program file

STAIR.WOL for the world.

3) The program e21.KRL and its world are below and on the following page.

/****** e21.krl - program to move Karel and move 1 beeper *****/

4) A complete list of instructions for Karel are listed on the last page.

Exercise: 1) Every morning Karel is awakened in bed when the newspaper, represented by a beeper, is thrown on the front porch of the house. Program Karel to retrieve the paper and bring it back to bed. The initial situation is given on the next page, and the final situation must have Karel back in bed (same corner, same direction) with the newspaper. Your program will need to be typed in using the DOS Editor. Use the world PAPER.WOL to test your program.
