What is Evidence-Centered Design?
  • Approach developed by ETS
  • Uses evidentiary reasoning to design the
    underlying principles of an assessment
  • Answers these questions
  • What complex of KSAs should be assessed?
  • What types of evidence would we need to show a
    test-taker has these KSAs?
  • What kinds of assessment items would allow us to
    gather this evidence?
  • Provides a set of tools for structuring a
    systematic approach to doing this

Phases of ECD
  • Domain Analysis
  • Big-picture narrative of the knowledge domain
  • Domain Modeling
  • Organization of the information in the domain in
    terms of
  • The aspect of proficiency of the test-taker in
    the domain
  • The kinds of things the test-taker might do to
    provide evidence of their proficiency
  • The kinds of situations that might make it
    possible to provide such evidence
  • Conceptual Assessment Framework
  • Blueprint for the actual assessment that takes
    all of this into account
  • The Assessment

  • Start with this process for your own assessment
    needs
  • Evaluate the fit of the instrument for your needs
  • Important Do not simply mix and match!

Foundations of proportionality
Find the missing number
Consider the function
Proportionality includes linearity, rate,
function, slope in graphs, interpreting tables
with an underlying rate
14
NCTM Curriculum Focal Points
Students graph proportional relationships and
identify the unit rate as the slope of the
related line. They distinguish proportional
relationships (y/x k, or y kx) from other
relationships, including inverse proportionality
(xy k, or y k/x).
  • Grade 7 Developing an understanding of and
    applying proportionality, including similarity.
  • Students extend their work with ratios to develop
    an understanding of proportionality that they
    apply to solve single and multistep problems in
    numerous contexts. They use ratio and
    proportionality to solve a wide variety of
    percent problems, including problems involving
    discounts, interest, taxes, tips, and percent
    increase or decrease. They also solve problems
    about similar objects (including figures) by
    using scale factors that relate corresponding
    lengths of the objects or by using the fact that
    relationships of lengths within an object are
    preserved in similar objects. Students graph
    proportional relationships and identify the unit
    rate as the slope of the related line. They
    distinguish proportional relationships (y/x k,
    or y kx) from other relationships, including
    inverse proportionality (xy k, or y k/x).
  • Grade 8 Analyzing and representing linear
    functions and solving linear equations and
    systems of linear equations.
  • Students use linear functions, linear equations,
    and systems of linear equations to represent,
    analyze, and solve a variety of problems. They
    recognize a proportion (y/x k, or y kx) as a
    special case of a linear equation of the form y
    mx b, understanding that the constant of
    proportionality (k) is the slope and the
    resulting graph is a line through the origin.
    Students understand that the slope (m) of a line
    is a constant rate of change, so if the input, or
    x-coordinate, changes by a specific amount, a,
    the output, or y-coordinate, changes by the
    amount ma. Students translate among verbal,
    tabular, graphical, and algebraic representations
    of functions (recognizing that tabular and
    graphical representations are usually only
    partial representations), and they describe how
    such aspects of a function as slope and
    y-intercept appear in different representations.
    Students solve systems of two linear equations in
    two variables and relate the systems to pairs of
    lines that intersect, are parallel, or are the
    same line, in the plane. Students use linear
    equations, systems of linear equations, linear
    functions, and their understanding of the slope
    of a line to analyze situations and solve
    problems.

They recognize a proportion as a special case of
a linear equation of the form y mx b,
understanding that the constant of
proportionality (k) is the slope and the
resulting graph is a line through the
origin. Students translate among verbal, tabular,
graphical, and algebraic representations of
functions.

Q1. Definition of MKT
  • By mathematical knowledge for teaching, we mean
    the mathematical knowledge used to carry out the
    work of teaching mathematics. Examples of this
    work of teaching include explaining terms and
    concepts to students, interpreting students
    statements and solutions, judging and correcting
    textbook treatments of particular topics, using
    representations accurately in the classroom, and
    effects of teachers mathematical knowledge on
    student achievement providing students with
    examples of mathematical concepts, algorithms, or
    proofs (Hill, Rowan, Ball, 2005).
  • We look across mathematical knowledge needed for
    or used in teaching, including pure content
    knowledge as taught in secondary, undergraduate,
    or graduate mathematics courses pedagogical
    content knowledge and curricular knowledge (also
    described by Shulman) both possibly taught in
    mathematics methods courses and what is more
    elusive, knowledge that, while also mathematical,
    is not typically taught in undergraduate
    mathematics courses and is not be entirely
    pedagogical. Mathematical knowledge for
    teaching, keeping the emphasis on mathematics and
    acknowledging that teachers may know and use
    mathematics that is different from what is
    required for other professions (Ferrini-Mundy,
    et. al., 2008)

Question 2
  • Teachers attitudes about being evaluated
