Stages in Developing Descriptors
  • 1. Conceptualisation
  • Clarifying the construct. What are we describing?
  • Collecting relevant example, systems
  • Deciding categories in the descriptive scheme
  • Clarifying key questions
  • 2. Construction
  • Creating the descriptor pool
  • Editing, drafting filling gaps in the
    description
  • 3. Validation
  • Qualitative through iterative workshops with
    teachers
  • Quantitative through IRT scaling of use in
    assessment
  • 4. Interpretation
  • Set thresholds between levels
  • Summarise developing proficiency

Conceptualisation
  • CEFR
  • CEFR descriptors observable, functional outcomes
    competence descriptors also mainly observable
    proficiency
  • Interaction (BICS) / Production (CALP)
  • Illustrative videos of 16-18 yr olds difficulty
    with BICS C2
  • LoS more complex than modern languages
  • Language aspects / non-language aspects
  • Discourse emphasis genres cognitive skills
  • Developmental linked to cognitive growth
  • Far less known about LoS than modern languages
  • 20 years experience with descriptors 1975-1995
  • 20 years developing descriptive scheme 1975-1995

5
Characteristics of LoS or (C) ALP
  • We/you know it involves more
  • specific, formal, abstract
  • explicit, detailed, conventionalised (
    expectations)
  • cohesive and structured (e.g. sequencing)
  • coherent (goal-oriented)
  • planning, self-monitoring, internal feedback,
    editing
  • rhetorical skills and structures, strategies
  • BUT
  • How much is really known about academic
    discourse?
  • Reception of exposition by the teacher
  • Interaction in class
  • Production by the teacher
  • To what extent are skills transversal a common
    core?

Key Questions I
  • Relationship to
  • content standards
  • European Qualifications Framework
  • CEFR
  • Categories to be described
  • Transversal categories as in Table 5 of ERDLE
    proposal (p52)
  • Subcategories of Recep, Inter, Prod, Interp,
    Evaluation, Mediation?
  • Cognitive skills strategies from Situation
    analysis (Beacco et al)
  • What else?
  • Style
  • concrete-salient features (CEFR-style) / abstract
  • Length including assumptions Can make a
    complaint B1
  • broad-holistic / atomistic-analytic / both
    (Fleming)

11
Key Questions II
  • Thresholds to be described
  • expected language proficiency levels
  • types of discourse
  • stages of cognitive development
  • strategies
  • How to deal with difficult parts (non-language)
    e.g. Bildung
  • consideration of others
  • critical thinking, sound judgement and courage to
    express it?
  • flexibility in thinking and argumentation

13
Construction
  • Creating a classified bank of descriptors
  • Collate / deconstruct all source systems
  • Eliminate doubles, redundancy
  • Identify gaps
  • Editing and drafting
  • Confirm style
  • Harmonise use of verbs (not done in CEFR
    English!)
  • Harmonise formulations
  • Create variations (for missing levels)
  • Author missing categories
  • Organisation
  • Classify with serial numbers
  • Translation to key languages / check translations
    with plurilinguals

15
Qualitative Validation
  • Analysis of teachers discussing proficiency
  • Video of two learners
  • Who is better? Why? Justify your choice
  • Repertory grid analysis of categories teachers
    use to compare quality
  • Sorting descriptors into categories
  • Pile of (maximum 60) descriptors
  • Set of (maximum 4) envelopes labelled with the
    relevant categories
  • Discard envelope
  • Tick ones that are clear, relevant and useful
  • Sorting descriptors into levels
  • Pile of (maximum 15) descriptors for same
    category
  • Set of (CEFR 6) envelopes labelled with levels
  • Discard envelope / Tick ones that are clear,
    relevant and useful

16
Quantitative Validation - Purpose
  • To construct a scale from the descriptors for the
    core construct
  • To bolt onto / link to this scale sets of
    descriptors for categories that prove to be less
    core areas
  • To find out/confirm what level specific
    descriptors are
  • To discover which descriptors do not work
  • To confirm communality of the interpretation of
    the descriptors across
  • Languages
  • Regions / countries / systems
  • Educational sectors

17
Quantitative Validation Steps
  1. Identify good/best descriptors from the pool
    after the qualitative validation
  2. Confirm the supposed level of these descriptors
  3. Create a set of overlapping checklists of c50
    descriptors (like ELP checklists) each checklist
    targeted at a level
  4. Define a rating scale Yes/No 0-4 for the
    descriptors
  5. Identify classes at approximately the right level
    for each checklist
  6. Arrange teacher assessment and/or self-assesment
    with the checklists
  7. Collect minimum 150 examples of each checklist
  8. IRT Rasch Model Rating Scale Analysis to build
    scale
  9. Eliminate descriptors with 80 or 20- (Rasch
    problem)

Quantitative Validation - Prerequisites
  • Construct is well-defined common understanding
    of what is being described/rated/scaled
  • Descriptors are well-formulated, clear and
    relevant
  • Teachers/learners are capable of making
    judgements about the areas concerned
  • There is a solid anchor design in the data
    collection

25
Setting Thresholds between Levels
  • Marking out equal intervals on the scale
  • Identifying jumps in content described, gaps
    between clusters of descriptors
  • Comparing to original scale author intention
  • Comparing to Waystage, Threshold, Eurocentres,
    Cambridge exam levels
  • Fine-tuning for equal intervals
  • Checking for consistency, coherence

26
CEFR 3.6 Salient Characteristics A2
  • The majority of descriptors stating social
    functions
  • greet people, ask how they are and react to news
  • handle very short social exchanges
  • discuss what to do, where to go and make
    arrangements
  • Descriptors on getting out and about
  • make simple transactions in shops, banks etc.
  • get simple information about travel and services

27
CEFR 3.6 Salient Characteristics B1
  • Maintain interaction and get across what you want
    to
  • give or seek personal views and opinions
  • express the main point comprehensibly
  • keep going comprehensibly, even though pausing
    evident, especially in longer stretches
  • Cope flexibly with problems in everyday life
  • deal with most situations likely to arise when
    travelling
  • enter unprepared into conversations on familiar
    topics

28
CEFR 3.6 Salient Characteristics B2
  • Effective argument
  • account for and sustain opinions in discussion by
    providing relevant explanations and arguments
  • explain a viewpoint on a topical issue giving the
    advantages and disadvantages of various options
  • Holding your own in social discourse
  • interact with a degree of fluency and spontaneity
    that makes regular interaction with native
    speakers possible
  • adjust to changes of direction, style and
    emphasis
  • A new degree of language awareness
  • make a note of "favourite mistakes" and monitor
    speech for them

31
US No Child Left Behind 2001-7
  • States have a legal duty to provide the support
    to ensure that every child is proficient in the
    academic language they need to be successful at
    school.
  • Must test this.
  • Must be at least a grade above and a grade below
    proficient. (not just the usual US master /
    non-master)

32
US No Child Left Behind 2001-7
  • No overall framework or common reference points
  • Testing-led dozens of consortia
  • No time for research
  • No systematic definition of the construct ALP
  • Confusion with English Language Arts (
    creative writing for native speakers)
  • or
  • Elaborated from language used in subject content
    standards
  • No definition of proficient 15 significantly
    different interpretations
  • Some states 3, some 4, some 5 grades all
    different names, numbers, concepts
  • CHAOS

Analysing Aligning Standards
  • Assumptions in Subject Standards
  • Elementary School observe, analyse, compare,
    describe, record
  • Middle School identify, recognise, compose,
    explain
  • High School recognise, describe, explain
  • (Bailey and Butler 2003)
  • Extracting the language features embedded in the
    content standards presented significant
    challenges .
  • Bailey, Butler and Sato (2005) have been
    successful developing standards-standards
    linkages that involve both language and content
    standards BUT procedures to establish such
    linkages remain to this day in their infancy

Classroom Research
  • From 2001
  • Analysis of functions in science classrooms
  • Teachers
  • Students
  • Repair strategies
  • (Bailey and Butler 2003)
  • BUT
  • All tests produced before any research results
    were available even in consortia aware of the
    problem

39
Teacher Expectations
  • Students must learn acceptable ways of presenting
    information to the teacher not usually
    explicitly taught
  • Very little study
  • Teachers are rarely explicitly aware of their
    language expectations
  • Dropped the idea of teacher interviews because
    anecdotal unreliable information
