Title: An Introduction to Strategic Reading Comprehension


1
An Introduction to Strategic Reading Comprehension
  • Art Graesser

2
Overview
  • Shallow versus deep comprehension
  • Levels of representation and processing
  • Theoretical frameworks
  • Strategies
  • Interdisciplinary projects with computer
    technologies

3
Wading in Shallow Waters
  • Shallow knowledge
  • Shallow comprehension strategies
  • Minimal comprehension training
  • Shallow tests
  • Shallow classroom questions
  • Unspectacular comprehension calibration of
    learners
  • Shallow theories
  • Shallow policy makers

4
Restoration of Hope
  • The escape of the Brazilian boa constrictor
    earned Harry his longest-ever punishment. By the
    time he was allowed out of his cupboard again,
    the summer holidays had started and Dudley had
    already broken his new video camera, crashed his
    remote control airplane, and, first time out on
    his racing bike, knocked down old Mrs. Figg as
    she crossed Privet Drive on her crutches.

  • A mushy, brown peach is lifted from the garbage
    and placed on the table to pinken. It pinkens,
    it turns hard, it is carried in a shopping sack
    to the grocers, put on a shelf, removed and
    crated, returned to the tree with pink blossoms.
  • In this world, time flows backward.

6
Levels of Discourse Structure
  • Graphemes and phonemes
  • Morphemes and words
  • Syntactic composition
  • Linguistic style and dialect
  • Explicit propositions
  • Referents of referring expressions
  • Common ground (shared knowledge)
  • Discourse focus versus presuppositions
  • Situation models (space, causality, goal
    structures) inferences
  • Embedded dialog
  • Configuration of multiple agents
  • Genre, registers, rhetorical structures
  • Plot configurations
  • Local and global coherence
  • Point of message -- theme
  • Goals and attitude of author

7
What is the ideal grain size?
  • Crude but teachable to teachers
  • Word/sentence interpretation
  • Links between sentences
  • Links to readers background knowledge
  • Theoretical natural categories (Kintsch,
    Graesser)
  • Surface code
  • Propositional textbase
  • Situation model
  • Text genre and rhetorical structure
  • Pragmatic communication
  • Psychometric categories (Oakhill, VanderVeen)
  • 3-5 construct limitation
  • Evidence centered design (Mislevy)
  • ETS, College Board
  • Dozens at a fine grain
  • Requires computers
  • Challenges of validation

8
Example Theories and Models in Discourse
Psychology
  • Text grammars (Van Dijk)
  • Bridging and given-new (Clark)
  • Scripts, plans, and schemas (Bower, Schank
    Abelson)
  • Structural affect theory (Brewer, Lehnert)
  • Structure-building framework (Gernsbacher)
  • The Reader model (Just Carpenter)
  • Constructionist theory (Graesser, Singer,
    Trabasso)
  • Construction-integration model (Kintsch)
  • Landscape model (van den Broek)
  • Event indexing model (Zwaan)
  • Memory-based resonance model (OBrien and Myers)
  • Embodied theoretical frameworks Indexical
    Hypothesis (Glenberg)

9
Five Metaphors for Text Understanding (Graesser
Britton, 1996)
  • Assembling a multilevel representation
  • The construction of a coherent structure
  • A dynamical system
  • Managing working memory
  • Inference generation

10
Theoretical Components
Levels of representation
Reader goals and assigned task
Knowledge and skill
Metacognition
Memory and attention
Cohesion and coherence
Information sources
11
What do the theories and models truly predict and
explain?
  • Directly articulated in the model
  • Naturally follows from the model, but not
    directly articulated
  • Ad hoc assumptions or parameters to accommodate
    data
  • Impossible to accommodate or out of scope of
    model
  • Do we draw the line at 2 or 3?

13
Observations on analysis of theoretical
predictions
  • Very few 2s even though they are perhaps most
    interesting
  • Status of predictions is often murky with respect
    to 3 versus 4
  • General theories of memory and cognition do not
    go the distance in explanatory adequacy. We need
    theories of discourse and pedagogy.
  • Problems with kitchen sink manipulations in
    informing us about effective theoretical
    components

14
Strategies and Strategy Interventions
  • iSTART Interactive Strategy Training for Active
    Reading and Thinking (McNamara 30)
  • LSAT RSAT diagnoser with iSTART (Magliano
    Millis)
  • Reciprocal teaching method (Palincsar Brown)
  • Concept mapping (Vitale Romance)
  • PALS Peer-assisted Learning Strategies (Fuchs)
  • CORI Concept Oriented Reading Instruction
    (Guthrie)
  • Text Structure (Williams)
  • Structure Strategy tutor (Meyer)
  • Question Asking and Answering (King, Guthrie,
    Gholson)
  • 3D Readers (Johnson-Glenberg)
  • Joke City (Yuill)
  • Indexing and embodiment (Glenberg)
  • Universal Learning Environments (Dalton
    Proctor)
  • Summary Street (Caccamise, Kintschs)

Good Job!

  • Question Taxonomy
  • (Graesser and Person,1994 Gholson Craig)
  • LEVEL 1 SIMPLE or SHALLOW
  • 1. Verification Is X true or false? Did an
    event occur?
  • 2. Disjunctive Is X, Y, or Z the case?
  • 3. Concept completion Who? What? When?
    Where?
  • 4. Example What is an example or instance of a
    category?).
  • LEVEL 2 INTERMEDIATE
  • 5. Feature specification What qualitative
    properties does entity X have?
  • 6. Quantification What is the
    value of a quantitative variable? How much?
  • 6. Definition questions What does X mean?
  • 8. Comparison How is X similar to Y? How is X
    different from Y?
  • LEVEL 3 COMPLEX or DEEP
  • 9. Interpretation What
    concept/claim can be inferred from a pattern of
    data?
  • 10. Causal antecedent Why did an event occur?
  • 11. Causal consequence What are the consequences
    of an event or state?

17
Status of Strategy
  • Strategy presses buttons in some circles
  • Strategies should be integrated with concrete
    examples and content
  • Strategies should not interfere with
    comprehension
  • Strategies are always context-sensitive rather
    than context-free

18
Strategy parameters to worry about
  • What level of representation is being tapped?
  • What prerequisite knowledge or skills are needed
    to apply the strategy?
  • What prerequisite knowledge or skills will yield
    maximal gains through the strategy?
  • How much training is needed for mastery?
  • Does the strategy need to be explicit and
    conscious? Or is unconscious induction adequate?
  • What are the relevant genres, registers, and
    content?
  • Can humans be trained or is a computer necessary?

19
Claims
  • Human teachers and trainers will not have enough
    expertise and time to apply complex
    context-sensitive strategies.
  • Computer technologies are in place for automation
    at many levels.

neck injuries. Why do passengers get neck
injuries in this situation?
