This session
  • What is think-aloud?
  • How does think-aloud reveal strategies?
  • Eliciting think-aloud data among young learners
  • Coding and analysing think-aloud protocols

What is think-aloud?
4
How can think-aloud reveal strategies?
5
What strategies do you see?
  • (dictionary work)
  • S SMART is usually an adj, it doesnt seem an
    adj here. SMARTS, (reads in dictionary). SMART,
    SMART is definitely not an adj. here, so Ill go
    for the verb. Oh, theres such a meaning for
    SMART, it means to sting. No? SMARTS the eyes,
    oh, yes, it is to sting, its this meaning then.
    SMART, let me see if therere any set expressions
    that go with it. Ah, I see an adj with a similar
    meaning here. a SMART blow, a SMART blow, a
    good beating (wrong in dictionary), this, need to
    remember this.

10
Can primary school children think aloud?
  • Children can do think-alouds, upper primary
    better than lower primary
  • Chamot El-Dinary (1999, p.331) students as
    young as grade 1 were often able to describe
    their thinking in rich detail
  • Gu, Hu, Zhang (2005) yes, but need intensive
    probing and immediate clarifications

Coding and analysing think-aloud data
15
Coding and analysing think-aloud protocols
  • Coding The quantitative approach to qualitative
    data
  • Where do codes come from?
  • Strategy coding What to code and how
  • Quality of strategy use
  • Coder subjectivity
  • Specificity of strategies

16
Coding The quantitative approach to qualitative
data Adapted from Bernard, 1996
17
Where do codes come from?
18
Our Coding Scheme
  • Top-down for framework
  • Initial scheme based on
  • Theoretical analysis
  • 3 empirical studies
  • O'Malley, Chamot, and Kupper (1989),
  • Goh (2002), and Vandergrift (2003)
  • Bottom up for fine-tuning
  • Adding, deleting, and adjusting till saturation
    point

19
Theoretical analysis The listening task
  • Simultaneous integration of information from
    multiple sources in WM
  • Massively parallel, interactive processing
    (Lynch, 2002, p. 39) of phonetic, phonological,
    prosodic, lexical, syntactic, semantic,
    pragmatic, and background information..

20
The listening task
  • Chaotic at first, both bottom-up and top-down
    processing to form a coherent mental
    representational framework (Kintsch, 1998) in WM.
    This framework then
  • serves as a perceptual filter to suppress
    irrelevant upcoming information and
  • fills meaning gaps through its influence on the
    listeners selection and use of comprehension
    strategies such as inferencing

21
The listening taskThree levels of cognitive
processing
  • Perceptual processing selectively attending and
    screening of incoming sounds
  • Parsing encoding for meaningful representation,
    i.e., making sense
  • Utilization elaborating to enhance meaning and
    to store it in LTM
  • Anderson (2000)

22
Listening strategies
  • Good listeners
  • Metacognitively
  • in control of the listening process,
  • actively engage in planning
  • monitor incoming input for congruence with
    expectations to construct a mental representation
    of the text in memory
  • Cognitively
  • monitor and direct their attention on task,
  • listen to larger chunks and use both top-down and
    bottom-up processing.
  • relate new information to existing world
    knowledge and/or personal knowledge, and
    critically evaluate the usefulness of the
    information
  • O'Malley, Chamot, and Küpper (1989) Vandergrift
    (2003)

23
Listening strategies
  • Poor listeners
  • Metacognitively
  • rarely engage in comprehension monitoring
  • Cognitively
  • easily distracted by unknown words or phrases and
    were unaware of their inattention
  • Use word-by-word, bottom-up decoding exclusively
  • have fewer elaborations, and do not make any
    connections between the new information and their
    own lives
  • O'Malley, Chamot, and Küpper (1989) Vandergrift
    (2003)

24
Listening strategiesbottom-up vs top-down
processing
  • Established way of thinking
  • higher proficiency - top-down processing
  • lower proficiency - bottom-up processing
  • (Chien Li, 1998 O'Malley, Chamot, and
    Küpper, 1989 Vandergrift, 2003)
  • Some recent findings
  • Wu (1998) two types of top-down processing
  • Facilitating successful comprehension, skilled
    listener
  • Compensatory less successful comprehension,
    unskilled listener
  • Tsui Fullilove (1998) less skilled listeners
    weak in automatic decoding, and have to use
    top-down support for compensation, i.e., need
    better bottom-up skills, less wild guessing
  • Field (2004) neither bottom-up nor top-down but
    lexical a rough attempt at a one-to-one match
    with a known item which potentially overrules
    contextual information and modifies perceptual
    (p. 373)

25
Bottom-up coding using NVivo
  • Apply initial coding scheme on think-aloud data
  • Add, delete, adjust categories based on data
  • Example

30
Coding procedures
  • Three independent coders
  • Use NVivo
  • Regular meetings for calibration
  • Agree to a final coding scheme
  • Cross coding to ensure consistency
  • Coder A Coder B
  • Coder B Coder C
  • Coder C Coder A

Coding and analysis Unresolved problems
34
Strategy codingWhat is coding for?
  • pattern finding tallies, e.g., repertoire,
    frequencies
  • hypothesis generation
  • insights exploration

35
Strategy coding
  • What do we code and how do we code
  • highlighting strategy presence, but not absence
  • mostly good strategies
  • How do we code the following?
  • motivation for strategy choice
  • quality of strategy use
  • flexibility of strategy use
  • efficiency of a strategy
  • orchestration of strategy use

36
Strategy codingQuality of strategy use From
whether to how
  • The same strategy often used by both a less
    successful pupil and a more successful
    counterpart (e.g., inferencing and prediction)
  • Good and poor listeners differed in other
    aspects, e.g.,
  • varying accuracy of bottom-up decoding,
  • retrieval of schemata of varying relevance, or
  • ability to form a relevant conceptual framework,
  • ability to adjust the framework according to new
    input, etc.
  • Do we need to code these qualitative differences?
    How?

37
Strategy codingCoder subjectivity
  • Quality of strategy use graded or binary?
  • effective vs ineffective
  • not at all effective, somewhat effective, very
    effective?
  • Whose perspective researchers (Etic) or
    learners (Emic)? e.g.,
  • maintaining on-task attention
  • continuing to listen despite difficulty

38
Strategy codingSpecificity of strategies
  • The greater specificity of the strategies, the
    more likely it is to find interpersonal
    differences.
  • However, increasing specificity of strategies can
    make a taxonomy very unwieldy, and findings less
    generalizable.
  • What is the optimal level of specificity? How is
    this to be determined?

39
Overall Summary
  • A Chinese fable (in Lushi Chunqiu Chajin)
  • A man from the state of Chu was traveling in a
    boat when his sword fell into the river. He
    instantly drew out his dagger and cut a mark on
    one side of the boat and said to himself this is
    where my sword fell. After the boat finally
    pulled ashore, he jumped into the water from the
    marked point of the boat and searched in vain for
    his sword.
  • Moral
  • when set out to get something, we need to get
    it the right way, or we risk not getting it at
    all.
