Workshop:
Instructor Exercises

Introduction

The goal of this set of exercises is to develop material using WLS for an environment which has access to a web server and also a RealAudio server. The course material should already be in html format.

This set of exercises will step the user through two types of authoring.

1. Delivering a lecture using the built in TEST slides. The steps are:
   • Download and configure the Instructor (Client) software.
   • Load the TEST slides into a WLS Lecture.
   • Deliver and encode an example Lecture using these slides.
   • Playback the example Lecture.
2. Optional exercise using your own slides uploaded to the web server.

Exercises

1. EXERCISE I
   Set up the WLS client software.
   1. Download the instructor (client) software for:
      Windows 95/NT Client Software. or UNIX Client Software (SGI Irix Only).
   2. Download the RealAudio encoder from RealNetworks
   3. Follow the Real Audio instructions and install the encoder.
      Instruction from RealAudio:   When prompted, choose Save to Disk and specify the directory where you want the RealEncoder installation program to be saved. Locate and launch the file you downloaded by exploring your hard drive or choosing the Run option in the Start menu. (The file is where your Web browser saved it.) This will begin the RealEncoder setup process.

   4. WLS can be setup to run in three different configurations:
      

      The HTTP server, Real Audio Server and the User machine are all separate machines.
      The HTTP server and the Real Audio Server are one machine and the User is using a separate machine.
      The HTTP server, Real Audio Server and the User machine are all the same machine.

      This exercise will be configured to run as follows:
      • Remote machine is the Web Server:   zagreb.csc.ncsu.edu
      • Remote machine is the RealAudio Server:  zagreb.csc.ncsu.edu
      • Local machine is the source of lecture material and audio encoding:   Machine you are using.
   5. End of exercise 1!
   
   
   
2. EXERCISE 2
   Now create your own slide set and deliver your first WLS Lecture.
   1. Run WLS:
      • To begin; click here
      • The page should look like:
        
   2. Select the class: TEST. Type TEST in the Class Name type-in field.
      
      
      The page should look like:
      
      Note: a detailed description of each of the terms in the above image can be found here
   3. Check the Instructor Configuration:
      1. Set the Class Information. Remember to Submit when finished.
      2. Set the Configuration.
         • Set the Capture Mode to either private or public.
         • Set the Audio Mode to external.
         • Set the Encoder Mode to remote.
      3. Set the Access.
   4. Begin the Lecture
      • Create the slide set. Click on the link
        
      • Create a new lecture by selecting New Lecture from the menu on the left.
        
      • Select the existing slide set, slides one through four and submit the list of slides.
        
      • Begin presenting the lecture by selecting Present from the menu list on the bottom of the Lecture Editor page. This will capture the audio part of lecture. Note, the audio encoder will run in the background on the local machine.
        
      • After the presentation, review the capture information by selecting Details from the menu list on the bottom of the Lecture Editor page.
      • Access this lecture as a student and navigate through the lecture you have just completed.
   
   
   
3. EXERCISE 3
   Advanced options for WLS:
   • Using the Drawing Tablet
   • Editing the slides in the lecture.
   1. Construct a new lecture adding some drawings.
      1. Repeat the previous EXERCISE and use the to start the JAVA^TM whiteboard.
         Add several drawings to the new lecture.
   2. Use the Editing slides option. Select the Slide Set then the Edit Slide option. Edit the slides.
   3. Use the Editing slides option. Alternatively, Select the Lecture then the Edit Slide option. Edit the slides.
   
   
   
4. EXERCISE 4 (Optional) If you have some HTML slides already prepared.
   Creating your own lecture.
   1. Construct a slide set from your HTML files.
      

      The directory where the slide set is stored is displayed and the slides which comprise the Lecture are listed.

   2. The author can now do the following:
      

      Create the slide set. Add slides. Make slides from images
