4What 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
5Phases 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

13Foundations of proportionality
Find the missing number
Consider the function
Proportionality includes linearity, rate,
function, slope in graphs, interpreting tables
with an underlying rate
14NCTM 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.

22Q1. 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)
