Diagnosing and Remediating Mathematical Problems

Using InCAS Software

Page 2: Stephen Albone Diagnosing and Remediating Mathematical Problems Using InCAS Software.

2

Defining Maths Difficulties

• Low Attainment

• Under Attainment

• Lack of Progress

Page 3: Stephen Albone Diagnosing and Remediating Mathematical Problems Using InCAS Software.

3

Reasons for Maths Difficulties

• Institutional

• Motivational

• Neuropsychological

Page 4: Stephen Albone Diagnosing and Remediating Mathematical Problems Using InCAS Software.

4

Institutional Factors

• Learning Environment

• Suitability for Atypical Learners

Page 5: Stephen Albone Diagnosing and Remediating Mathematical Problems Using InCAS Software.

5

Motivational Factors

• Status of Mathematics in Society

• Effect of Low Achievement

• Perceived Control– Competence & Contingency

• afraid to make mistakes• failure avoidance behaviour• strong negative reactions• associated with EBD, MLD & SLD

6

Helping Motivation

• Well Structured Tasks

• Achievable Goals

• Immediate Feedback

• Cross-age Peer Tutoring

Page 7: Stephen Albone Diagnosing and Remediating Mathematical Problems Using InCAS Software.

Neuropsychological Factors

• Magnitude Representation– Internal Number Line– Number Sense– Approximate Number System (ANS)

• Symbolic Representation– Uses verbal systems to give semantic

meaning to numerical quantities

• Spatial Representaion– Subitising?

Magnitude Representations

Verbal Representations

Visual/Spatial Representations

Learning to Count

• Counting Word Sequence

• One-to-One Correspondance

• Cardinal Word Principle

• Order-Irrelevance Principle

• Abstractness Principle

Page 10: Stephen Albone Diagnosing and Remediating Mathematical Problems Using InCAS Software.

10

Early Arithmetic

• Calculation Strategies– count all– counting on from first– counting on from higher– recall

Page 11: Stephen Albone Diagnosing and Remediating Mathematical Problems Using InCAS Software.

11

The Role of Memory

• Working Memory

• Semantic (Long-Term) Memory

Page 12: Stephen Albone Diagnosing and Remediating Mathematical Problems Using InCAS Software.

12

Helping Arithmetic

• Instant feedback

• Evaluate reasons for incorrect responses

• Encourage new strategies

• Encourage answer checking using primitive strategies

Page 13: Stephen Albone Diagnosing and Remediating Mathematical Problems Using InCAS Software.

13

Helping Memory

• Use memory aids

• Literacy remediation strategies may help

Verbal vs. Abstract Problems

Page 15: Stephen Albone Diagnosing and Remediating Mathematical Problems Using InCAS Software.

15

Verbal vs. Abstract Problems

Proposed Developmental Sequence:

1. verbal single-reference

2. symbolic single reference

3. symbolic double-reference

4. verbal double-reference

Page 16: Stephen Albone Diagnosing and Remediating Mathematical Problems Using InCAS Software.

DD or MLD?

• Developmental Dyscalculia– Specific Impairment of Cognitive Function– Defective Number Module Hypothesis– Core Deficit Hypothesis

• Mathematical Learning Difficulties– Comorbidity with Other SEN’s
