MDA at a Glance• instructional specific information
• focus on conceptual understanding, procedural accuracy, & mathematical thinking
• incorporates 4 effective assessment practices
•Student interest assessment•C-R-A assessment•Error pattern analysis•Flexible mathematics interview
•can be completed in an ordinary classroom period
Important Concepts
•Level of Cognitive Understanding
•Level of Expressive Understanding
•Mathematical Thinking
•Procedural Accuracy
•Instructional Hypothesis
Level of Cognitive Understanding
•At what level(s) do students understand the target mathematics?
•Three levels:
•concrete (objects/manipulatives)
•representational (drawing)
•abstract (numbers/symbols only)
Level of Expressive Understanding
•In what manner can students show their understanding?
•Recognition (receptive level)
•Doing (expressive level)
Mathematical Thinking•Are students able to think about mathematics in ways...
•1) that are reasonable?
•2) that show understandings of how relevant mathematics concepts/skills across the curriculum “fit” together in order to problem solve?
•Reasoning
•Approach to Problem Solving
Procedural Accuracy
•Are students able to use effective algorithms/procedures in order to successfully compute?
•Algorithms
•Procedures
Instructional Hypothesis
•Provides you with a focused approach to teaching that specifically addresses the needs of your students based on the results of a mathematics dynamic assessment.
Instructional Hypothesis
•Components:
•Context
•What students can do
•What students cannot do
•Reason
“Given ________,
students can _______
students cannot ______,
because __________.”
Mathematics Dynamic Assessment: Description
•Student Interest Inventory
•C-R-A Assessment
•Error Pattern Analysis
•Flexible Interview
Student Interest Inventory•Ask students to describe interests they have in a variety of areas in a format you can pick up and review. For example:
•things they like to do with friends
•things they like to do alone
•things they do with their family
•hobbies
•interests or special talents they have
Student Interest Inventory
C-R-A Assessment•Identify target concept (e.g., comparing fractions)
•Develop 3-5 assessment items:
•concrete, representational, abstract levels
•recognition and expressive response formats
•Create concrete, representational, & abstract centers
•Develop process for students responding to and showing you their responses
•Evaluate student performance at each level of understanding and response format
Error Pattern Analysis•Review student responses
•Determine whether students consistently use faulty procedures for responses that are incorrect
•Evaluate the meaning of the error pattern...
•does it represent lack of conceptual understanding?
•does it represent lack of pre-requisite knowledge?
•does it represent sensory-motor problems?
•does it represent impulsivity or distractibility?
What Does the Error Pattern Mean?

Flexible Interview•“Listen” for student’s mathematical thinking based on problems to which they have responded...
•ask them to describe to you how the solved the problem
•ask them to “teach” you how to solve the problem
•ask them to watch & listen as you solve the problem and to “catch” you doing something incorrect
•use concrete materials or drawings to further explore student understandings
