3. Claims
1. ‘Understanding’ is important
2. ‘Skills’ are important
3. If you are already annoyed I mention
‘understanding’ first, you may switch around
claims 1 and 2
4. You might even not like my use of the word
'understanding'. Now stop bickering. Both are
important. :-) Let's see how we can reinforce
both.

The Math Wars

13. ‘Understanding’ difficult term
• Learning that adds new knowledge to the learner’s
memory with little or no change in prior knowledge
is monotonic.
• If the learner must override or reject his or her
prior knowledge, his or her knowledge base shrinks
as well as grows, so learning is nonmonotonic
(Ohlsson, 2011).
• Cognitive change of this latter sort is variously
referred to as attitude change, belief revision,
conceptual change, restructuring, theory change,
and deep learning (Ohlsson, 2011).
14. Hiebert and Lefevre
• Procedural knowledge (knowing how)
• Formal mathematical language, algorithms and rules for solving
mathematical problems.
• Generates problem solving behaviour which is not always
meaningful and generalizable.
• Conceptual knowledge (knowing why)
• Product of a linking process, which creates relationships between
existing knowledge and information that is newly learned.
• Can be implicit or explicit, however it is flexible, not tied to specific
problem contexts and is therefore generalizable.
Hiebert, J., & Lefevre, P. (1986). Conceptual and procedural knowledge in mathematics: an introductory
analysis. In J. Hiebert (Ed.), Conceptual and Procedural Knowledge: the Case of Mathematics (pp. 1-27).
Hillsdale, N. Jersey: Lawrence Erlbaum Associates.
15. They defined conceptual understanding as ‘‘the
comprehension of mathematical concepts, operations, and
relations’’ and procedural fluency as the ‘‘skill in carrying
out procedures flexibly, accurately, efficiently, and
appropriately’’ (p. 116).
Furthermore, ‘‘the five strands are
interwoven and interdependent in the development of
proficiency in mathematics’’ (ibid.). Kilpatrick et al. (2001)
• Very influential with NCTM
• No very tight definitions
Adding it up (Kilpatrick et al.)
16. The ‘iterative’ model
(Rittle-Johnson, Siegler, & Alibali, 2001)
• Procedural and Conceptual knowledge develop in a gradual, hand-in-
hand process.
• Causal, bidirectional relations.
• Need to consider the processes that underlie performance not just the
outcomes.
Rittle-Johnson, B., Siegler, R.S., and Alibali, M.W. (2001). Developing
conceptual understanding and procedural skill in mathematics: an
iterative process. Journal of Educational Psychology, 93, 2, 346-362.
18. Another aspect: salience
Attractiveness of certain actions e.g. ‘work out
brackets’. This also depends on prior knowledge
• (x+2)(x+4)=-1
• (x+2)(x+4)=7
• (x+2)2=16
• Root signs
• ax2+bx+c=0
19. Star’s reconceptualisation
Star (2005) described in terms of ‘knowledge quality’
(De Jong and Ferguson-Hessler 1996) and knowledge
type.
Star, J. R. (2005). Reconceptualizing procedural knowledge. Journal
for Research in Mathematics Education, 36(5), 404–411.
20. Rittle-Johnson,Schneider and Star (2015)
• Review
• Two directions
• In 1998, Rittle-
Johnson and Siegler
concluded that there
is no fixed order in
the acquisition of
mathematical skills
versus concepts (p.
80).
• In 2015, order
unclear
• More research
22. Another example: algoritmes
• Fan & Bokhove (2014)
• (Standard-)algorithms often unfairly linked to ‘rote’,
‘lower’, no understanding. Givvin et al. (2009):
‘‘very algorithmic’’, ‘‘rule-orientated’’
• In Canada at one point even not mentioned at all
• Kamii and Dominick (1997) ‘‘Algorithms are harmful
to children’s development of numerical reasoning
for two reasons: (a) they ‘unteach’ place value and
discourage children from developing number sense,
and (b) they force children to give up on their own
thinking’’(p. 58).
23. But…
• Dahlin and Watkins (2000), link memorization and
understanding through ‘‘repetition’’.
• Meaningful repetition can ‘‘create a deep
impression’’ which leads to memorization, and it
can also lead to ‘‘discovering new meaning’’ which
in turn leads to understanding (Li, 1999).
• And also: "many different kinds of procedures, and
the quality of the connections within a procedure
varies" (Anderson, 1982 cited in Star, 2005).
• So we wrote we’d love to see standard algorithms
‘reinstated’.
26. Does PISA really say this?
• Not really
• Depends on what you look at
• Strong relationship ‘memorisation and
understanding’

28. OECD report
“Our analyses suggest
that to perform at
the top, students
cannot rely on
memory alone; they
need to approach
mathematics
strategically and
creatively to succeed
in the most complex
problems.”

30. TIMSS - cognitive domains
• The first domain, knowing, covers the facts,
concepts, and procedures students need to know.
• Applying, focuses on the ability of students to apply
knowledge and conceptual understanding to solve
problems or answer questions.
• The third domain, reasoning, goes beyond the
solution of routine problems to encompass
unfamiliar situations, complex contexts, and multi
step problems.
31.
32. TIMSS
The good scores of East Asian students seem to
contradict the assumption that Asian classrooms are
traditional and aimed mainly at low-level cognitive
goals (e.g. emphasizing memorization), which has
been called a ‘‘Paradox of the Asian learner’’ (Biggs
1994, 1998).
Memorisation AND understanding.
33. Differences between PISA and
TIMSS
• PISA more problem solving
• Both very much influenced by IQ, but PISA more so
than TIMSS (Rindermann, 2007).
• TIMSS more curriculum oriented. (Rindermann &
Baumeister, 2015)
35. Language
• TIMSS reading
demand
• Number of Words
• Vocabulary
• Symbolic Language
• Visual Displays
• TIMSS-PIRLS
relationship report:
poor readers did
worse than better
readers but were
doubly disadvantaged
by more reading.
• Be aware of this!
36. Example questions
• PISA toevoegen

39. Example how Asia might link memorisation
and understanding: variation
Might facilitate schema building. Not an automatic
process

40. Where to go next?
• Focus on skills AND understanding
• Research linking fMRI with algebra, for example
Cognitive Tutor
• Research on reading demand and assessment items
(e.g. student looking at Canada Ontario v England)
• Relation between ‘memorisation and
understanding’ (Asia hype, schemas?)
• Strong relations between education,
(neuro-)psychological research and computer
science (e.g. Rotation skills)
