Title: Adapting Maths Support Centres to Webwork


1
Adapting Maths Support Centres to Webwork
  • Nuala Curley
  • UCD

2
Adapting Maths Support Centres to Webwork
  • Increased use of online teaching resources.
  • Research in Neuroscience.
  • Maths Support Centres personal contact.
  • Adapt webwork.

3
What is WeBWorK?
  • Internet-based system for generating tutorial
    exercises.
  • Library of over 2500 problems.
  • What areas are covered?

4
How is WeBWorK used?
  • Use Library problems.
  • Edit problems.
  • Write your own problems.

5
Example
  • Don't show this problem on the next update.
  • Add this problem to the target set on the next
    update.
  • If f(x)Cos (sin(x2)) , find f(x)Find f(2).
  • File name Library/maCalcDB/setDerivatives5ChainRu
    le/s2_5_7.pg
  • Edit it Try it

6
Advantages
  • Gradually build knowledge of a concept.
  • Individualised versions.
  • Limited trials.
  • Thinking timemotivation.
  • Immediate feedback.
  • Sets automatically graded continuous monitoring.
  • Very suitable for large classes.
  • Not multi-choice.

7
Disadvantages
  • Student difficulties
  • Entering data.
  • Prior knowledge may be needed.
  • Students have no understanding of topic.
  • Lecturer difficulties
  • Takes time to become familiar with its use and
    build up a well designed set of questions to
    match your course.
  • Support Centre difficulties
  • unnecessary extra work.

8
Entering difficulty
  • BOMDAS eg
  • If you enter 3/45 3.75
  • but if you enter 3/(45) 3/20.
  • Enter Sin2t you get (Sin(2))t.
  • v(2x) must be entered as (2x)1/2.

9
Further example of difficulty in entering data
  • If you want to enter for example 23Sin24x
  • 23sin2(4x) is wrong.
  • You must enter something like
  • 23(sin(4x))2
  • or
  • 23sin(4x)2.
  • Students can use the "Preview Button" to see
    exactly how their entry looks.

10
Prior knowledge may be needed
  • For example to answer a question on the domain of
    a function students must be familiar with
    interval notation.
  • Q1. What is the domain of
  • f(x)(x2-4)/(x-2) where x is a real number.
  • Input (-8,2)U(2,8) in this fashion only.

11
Students have no understanding of topic.
  • MSC then becomes a teacher of the topic from
    basics.

12
How does this effect the Maths Support Centre?
  • Considerable extra work for the centre
  • Inputting data.
  • Covering prior knowledge required.
  • Teaching.

13
Significantly Reducing Difficulties
  • Introductory course on entering data.
  • Matching lecture, tutorial and webwork.

14
Trial planned next year for Commerce students in
UCD
  • Size of class approx 600.
  • Small size tutorials.
  • Short webwork at end of the tutorial.
  • Marks allocated for webwork, mid term exam and
    final exam.

15
Conclusion
  • Excellent Resource.
  • Use of it needs careful preparation and planning.
  • Research needed to ascertain its true value.
  • Library needs constant updating with increase in
    level of courses covered.
