Diagnostic Testing in Mathematics
  • A stepwise process to ease the school /
    university interface
  • Dr CDC Steele
  • School of Mathematics

2
Why ?
3
Why ?
  • Give individual students an idea of strengths and
    weaknesses

4
Why ?
  • Give individual students an idea of strengths and
    weaknesses
  • Build up profile of classes as a whole, tailor
    courses etc.

5
Why ?
  • Give individual students an idea of strengths and
    weaknesses
  • Build up profile of classes as a whole, tailor
    courses etc.
  • Use to assign students to most appropriate
    lecture course

Why ?
  • Give individual students an idea of strengths and
    weaknesses
  • Build up profile of classes as a whole, tailor
    courses etc.
  • Use to assign students to most appropriate
    lecture course
  • Identify students most in need of extra help

The Real Test
25
The Real Test
  • Takes place in week 0 (freshers week)
  • 80 minutes for test A
  • 40 minutes for test B
  • Tests divided into sections of 4 questions on
    similar topics
  • Profile of marks across sections more important
    than total mark
  • Students informed that mark does not count.

26
Test A
  • Section A H. Pre-A-level and P1,P2 (C1,C2,C3)

27
Test A
  • Section A H. Pre-A-level and P1,P2 (C1,C2,C3)
  • A Algebra
  • B Trig and Geometry
  • C Series
  • D Functions
  • E Polynomials
  • F Logs / Exponentials
  • G Differentiation
  • H Integration

28
Test A

  • A Algebra
  • B Trig and Geometry
  • C Series
  • D Functions
  • E Polynomials
  • F Logs / Exponentials
  • G Differentiation
  • H Integration
  • Sections I L
  • P3 (C4)

Possible Change 2005
  • Multiple-Choice ??
  • Options for
  • I knew this once but I have forgotten
  • I have never known this
  • Marked by optical reader

32
Output
  • Mark (correct or wrong) for each question
  • Mark out of 4 for each section
  • Profile of marks for various section
  • Number of sections A-H 3 or 4 out of 4
  • Number of sections I-L 3 or 4 out of 4
  • Total mark A-H
  • Total mark A-L

33
Destination Courses Test A
  • 1P1 most advanced
  • 1Q1 (1M1) intermediate
  • 1R1 most basic
  • Allocation done on basis of previous results,
    diagnostic tests, student opinions
  • Allocation on web-page . Monday week 1

34
To qualify for 1P1
  • In combination with previous results
  • Large number of 3 or 4 out of 4 sections across
    A-L
  • Threshold totals A-H and A-L

35
To qualify for 1Q1
  • In combination with previous results
  • Reasonable number of 3 or 4 out of 4 sections
    across A-H
  • Threshold total A-H

36
The QR borderline
  • Students with decent previous qualifications but
    poor performance on diagnostic test
  • Attend 1Q1 for weeks 1-3 , take another test in
    week 4

37
Tutorial Groups
  • Students placed in small group tutorials with
    students of similar ability / progress.
  • Sometimes specifically selected by being strong /
    weak on particular topics.
  • Diagnostic test returned at first tutorial session

38
General Profiles
  • Profiles of classes built up from diagnostic test
    results.
  • Sent to maths staff and staff in relevant
    schools. Useful for all 1st year teaching.

The Followup Process
43
The Followup process
  • A student will
  • Check sections allocated
  • Look at references provided
  • Ask at tutorials or elsewhere
  • Do practice WebCT questions
  • Do real WebCT questions

44
Allocation of Sections
  • Up to 2 sections chosen for students on 1P1 and
    1Q1.
  • 1P1 may include A-L (early unlikely)
  • 1Q1 may include A-H
  • Sections and procedure shown on web-page

45
Allocation of sections to students Individual
programme of work for each student
46
References for followup work
47
References for followup work
  • References as in those for mock test
  • HELM modules now also available
  • Assistance also available in tutorials

48
Practice WebCT Questions
  • Computerised questions similar to those in real
    assignment.
  • Sections A-H, I-L etc.
  • Can be done as many times as desired
  • Random questions / parameters etc.
  • Feedback given
  • Also, very simple practice questions as a guide
    to WebCT.

49
Real WebCT Questions
  • Questions on relevant topic (similar to practice
    questions)
  • Enter a numerical answer or mutliple-choice
  • Randomisation of questions / parameters
  • Deadline, Friday of week 4
  • Counts towards 1P1 or 1Q1 coursework

Conclusions
  • Students allocated to appropriate classes
  • Students provided with profile of strengths and
    weaknesses
  • Staff provided with appropriate profiles of
    classes
  • Students directed to resources on weak topics
