  • Step 1: Arrange access to needed equipment.  You'll need:
    • A USB flash memory drive with at least 250 megabytes (one quarter gigabyte) of free space.  You will use it for homework all semester and should bring it to lab.
    • Access to a windows computer capable of playing videos with sound with a high speed internet connection
      • Any computer lab at UTEP would be fine, but you'll need to bring your own headphone with a 3.5mm plug
      • A home computer or laptop with speakers or headphone and high speed internet connection would be fine too.  
        • UTEP's wireless internet or DSL may not sustain the needed connection speed 
        • Please use a headphone if you watch these videos in a public place
      • cJES can work on a linux or mac computer, but we can't help.  
        • Don't delay your homework trying to figure this out!
        • cJES is not JES
          • Versions of JES distributed by Georgia Tech's MediaComp project are missing important features needed for this course
  • Step 2: Download, unzip, and learn to start cJES  
    • You only need to do this once.  You will use cJES in every lab this semester.
    • Unzip to a folder named "cjes" on your USB flash drive.
    • To start JES, click on the "jes.exe" program in the cjes folder.
    • Also: Bring your USB drive to labs!
  • Step 3: Obtain the Lab 1 homework (lab2 prep) worksheet 
    • Download and print either of the following (the two files contain the same worksheet)
    • Note:
      • Every lab will have a prep worksheet due at the beginning of each lab session
    • Two approaches
      • Easiest: Print the worksheet and answer the questions using a pen or pencil
      • Ambitious: download the file and answer using word.  Note that you will need to draw some graphics (word supports this, but you'll need to know its fancy features and fuss a bit)
  • Step 4: Follow the worksheet instructions while using the internet-connected windows computer and cJES from your USB drive
    • They require you to answer questions after watching each of six short (2 to 7 minute) instructional videos
      • Links to the videos are at the end of this web page
      • You can watch or pause each video as many times as you like.
    • The first three sections are required, the last three are optional for extra credit.
    • The worksheet should require less than 90 minutes to complete.

    Collaboration and academic integrity

    All of these short (2-7 minute) instructional videos are in HD. 
    • If a video appears fuzzy, click on the gear symbol and select the highest resolution.  
    • If they are too small, you can select a larger image or full screen views.
