Advance OrganizerMDA at a glanceImportant conceptsMDA descriptionMDA video modelReviewQuestions/DiscussionMathVIDS information
MDA at a Glanceinstructional specific informationfocus on conceptual understanding, procedural accuracy, & mathematical thinkingincorporates 4 effective assessment practicesStudent interest assessmentC-R-A assessmentError pattern analysisFlexible mathematics interview
can be completed in an ordinary classroom period
Important ConceptsLevel of Cognitive UnderstandingLevel of Expressive UnderstandingMathematical ThinkingProcedural AccuracyInstructional Hypothesis
Level of Cognitive UnderstandingAt what level(s) do students understand the target mathematics?Three levels:concrete (objects/manipulatives)representational (drawing)abstract (numbers/symbols only)
Level of Expressive UnderstandingIn what manner can students show their understanding?Recognition (receptive level)Doing (expressive level)
Mathematical ThinkingAre 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?ReasoningApproach to Problem Solving
Procedural AccuracyAre students able to use effective algorithms/procedures in order to successfully compute?AlgorithmsProcedures
Instructional HypothesisProvides 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 HypothesisComponents:Context What students can do What students cannot do Reason Given ________,students can _______students cannot ______,because __________.
Mathematics Dynamic Assessment: Description Student Interest InventoryC-R-A AssessmentError Pattern AnalysisFlexible Interview
Student Interest InventoryAsk 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 friendsthings they like to do alonethings they do with their familyhobbiesinterests or special talents they have
Student Interest Inventory
C-R-A AssessmentIdentify target concept (e.g., comparing fractions)Develop 3-5 assessment items:concrete, representational, abstract levelsrecognition and expressive response formatsCreate concrete, representational, & abstract centersDevelop process for students responding to and showing you their responsesEvaluate student performance at each level of understanding and response format
Error Pattern AnalysisReview student responsesDetermine whether students consistently use faulty procedures for responses that are incorrectEvaluate 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 InterviewListen for students mathematical thinking based on problems to which they have responded...ask them to describe to you how the solved the problemask them to teach you how to solve the problemask them to watch & listen as you solve the problem and to catch you doing something incorrectuse concrete materials or drawings to further explore student understandings
