3Purpose of this Workshop
- The need
- The US ED MSP Program requires federally funded
programs to report observed gains in teacher
content knowledge - Measures of teacher content knowledge are not
necessarily already available - Overall goals for this workshop
- Discuss in depth the concept of mathematical
knowledge for teaching (MKT) - Provide basic knowledge for using, adapting,
and/or developing assessments for MKT for teachers
4Workshop Flow
- The construct of MKT
- Gain familiarity with the construct of MKT
- Examine available MKT instruments in the field
- Assessment Design
- Gain familiarity with the Evidence-Centered
Design approach - Begin to design a framework for your own
assessment - Assessment Development
- Begin to create your own assessment items in line
with your framework - Assessment Validation
- Learn basic tools for how to refine and validate
an assessment - Plan next steps for using assessments
5Scope of Purposes for AssessingTeacher MKT
- Research on teaching
- Teacher certification
- Diagnosis for individual teachers where PD is
necessary - Discussion points for professional development
- Evaluate knowledge growth that occurs in a PD
program
Focus is here
6What We Are Not Emphasizing
- Teachers opinions, attitudes, beliefs
- Teachers enacted practices
- Though similar principles of instrument
development would apply
7Important Caution
- Our emphasis is on evaluating programs, not
individual teachers - We are not discussing assessments that will have
consequences for individual teacher evaluation or
employment decisions
8Sources of Instruments
- Off-the-shelf
- Adaptations of off-the-shelf
- Newly developed

13Getting to Know You
- Name and region
- Setting where you work
- Grade-level focus
- Content focus
- Purpose for attending this workshop
14What questions do you have that you would like
answered in these two days?
- Can we realistically address reliability/validity
for small people? - Is what were doing making a difference to
student achievement? - What role does value-added assessment play?
- How do we measure MKT?

16Our ExampleThe Scaling Up SimCalc Project
- The central question
- Can a wide variety of middle school math teachers
use - an integration of technology, curriculum, and TPD
- to increase student learning
- of complex and conceptually difficult
mathematics? - Two randomized experiments
- 7th Grade 2005-2007
- 8th Grade 2006-2007
17Worked in 8 Regions in Texas
18Intervention An Integration of Technology,
Curriculum, and TPD
19TechnologySimCalc MathWorlds
- Designed to help students make mathematical
connections - Dynamic, interactive links between representations
20Curriculum Teachers Usea 3-Week Replacement Unit
- Proportionality (7th Grade)
- Linear function in the form ykx
- Rate
- Linear Function (8th Grade)
- Linear function in the form ymxb
- Average rate
21Teacher ProfessionalDevelopment
- Sequence of summer workshops totaling 6 days
- Training and planning opportunities for
- Mathematical content
- Software
- Curriculum materials
22The Assessments
23Purposes of theMKT Assessments
- To assess teacher learning in our workshops
- To examine the relationships between student
learning and teacher MKT
