Title: Learning through Doing with LONCAPA


1
Learning through Doing withLON-CAPA
  • Ray Batchelor
  • Veselin Jungic
  • Faculty of Science
  • Simon Fraser University

2
Agenda
  • Introduction (V. Jungic)
  • Demonstration Lon Capa The Learning Online
    Network with CAPA (R. Batchelor)
  • Discussion

3
Facts
  • Three calculus courses
  • Class size 200 700
  • 1200 students altogether
  • Numbers
  • Ten weeks
  • One assignment per week
  • Twenty questions per assignment

4
Problem
  • Mark
  • assignment questions in three months.

5
BIG Problem
  • Find resources to mark a quarter of one million
    assignment questions per semester.

6
Solution
  • TA spends 1 minute per assignment
  • Collecting assignments
  • Marking 1 question per assignment
  • Recording marks
  • Returning assignments
  • Marking
  • 3 marks for handing the assignment in
  • Up to three marks for the marked question

7
Cost
  • 1200 students x 10 assignments x 1 minute
  • 12000 minutes 200 TA hours
  • More importantly Students do not get the right
    feedback about their work

8
What To Do?
  • Options
  • Give up on marking assignments?
  • Keep the status quo?
  • Ask the Chair for more money?
  • Or

10
But Where To Go?
11
LonCapa
  • Open Source Distributed Learning Content
    Management and Assessment System
  • Sharing and using online learning and assessment
    materials across institutions and disciplines.
    Now.

12
PH GradeAssist
  • Developed by Prentice Hall
  • Disciplines Chemistry, Physics, Engineering,
    Math, Statistics
  • http//www.prenhall.com/phga/

13
iLrn
  • Developed by Brooks/Cole
  • iLrn is an integrated testing, tutorial, and
    class management system.

Lyryx
  • Lyryx Learning Inc. ("Lyryx") is a Canadian
    corporation specializing in the design,
    development, and delivery of e-learning
    solutions.

15
Maple TA
  • Maple T.A. supports complex, free-form entry and
    intelligent evaluation of responses, making this
    system useful for mathematics, science, or any
    course that requires mathematics.

16
Features
  • Browser-based interface
  • Question banks
  • Self created/ Shared/ Provided
  • Different types of questions
  • Algorithmic multiple-choice, true/false,
    fill-in-the-blank, essay, numerical, formula,
    randomly labeled, graph
  • Automatically graded assignments
  • Gradebook
  • Communication Tool

17
Benefits
  • We have demonstrated that networked tools can
    complement traditional teaching methods to
    enhance learning and improve efficiency while
    establishing and maintaining high performance
    standards. Motivated students have clearly
    benefited as they have taken advantage of the
    learning opportunities made possible by this
    technology.

    Traditional Teaching Enhanced Achievement in a
    500-Student Course, Chapter in "Interactive
    LearningVignettes from America's Most Wired
    Campuses", edited by David G. Brown, p. 51, ISBN

Improved Exam Performance

19
Improved performance especially of female students
  • Grade distribution for male and female students
    for a two-semester course (Phy231 and Phy232).
    Phy 231 was taught the traditional way and in
    Phy232 CAPA was used.

20
Challenges
  • One of the most significant challenges of
    implementing ALN technology in the classroom is
    the preparation and testing of questions and
    problems.
  • One issue that we need to continue to address is
    the negative impact of student-created cheating
    web sites
  • Another challenge is the need to develop
    improved discipline-specific standards

22
Students Are Happy
  • This is the best method of submitting homework.
    It makes students keep up to date with the
    material, and the discussion below each question
    helped me understand a lot of them better.
  • Survey performed in 2003-3 for SFU Chemistry
    120/121

23
And No So Happy
  • Q What particular aspects of online assignments
    were the most frustrating?
  • A Entering the answer in the correct form.
