Existing TILT Registration System

• Designed for University of Texas
• Connected to LDAP database
• To use their system, you need to create an LDAP
  database

3
Existing Quizzing System

• Connects to registration info in LDAP database
• Quiz itself written in HTML/JavaScript
• Quiz uses cookies to hold results
• At the end of the quiz, results are passed onto
  the LDAP database

Our registration/quizzing

• We needed a students registered for an
  introductory course to register
• We wanted them to answer a customizable set of
  questions
• We wanted to analyze the data
• -name/section
• -scores
• -answers

5
Efforts to customize

• Looked at getting existing TILT system up and
  running and then modifying
• -LDAP database setup difficult
• -documentation poor
• -HTML/JavaScript/PHP code difficult to read

6
Efforts to customize, cont.

• Looked at using WebCT briefly
• -Didnt want the overhead of creating WebCT
  courses
• -Other schools have used blackboard for the
  quizzing system

7
Writing our own registration/quiz

• Downloaded some free PHP scripts that did
  quizzing
• Found modifying these scripts too time consuming
• Decided to write registration/quizzing locally

8
Principles of system

• PHP as the scripting language to perform
  processing
• Use delimited text files to keep track of student
  data, question data, results data
• This format is easily manipulated in UNIX and
  Windows

Registration

• We obtained student data from registrar after
  attending a workshop on FERPA (student records
  and privacy issues)
• Provided in Excel format, which we converted to
  delimited text

11
Registration Program

• We wrote a PHP script to that looked up student
  data
• The PHP script then recorded the data in a PHP
  Session variable, which basically means it stored
  it in a cookie
