Scoring Training Guide. Goals of Assessment We must ensure that tests measure what is of value, not just what is easy to test. If we want students to.

1…analyzing student thinking and improving instruction Welcome Math LeadersMac Scoring TrainingYear 14…analyzing student thinking and improving instruction
2What is MARS?Mathematics Assessment Resource Service - Nottingham, England not outer spaceMAC = Mathematics Assessment Colloborative, part of the Silicon Valley Mathematics Initiative - Marin, San Mateo, Santa Clara, Santa Cruz, Alameda Counties, Contra Costa County, and Monterey CountyTests are often called MAC tests or BAM (Balanced Assessment in Mathematics)
3MAC Update 2012 50 School Districts plus other states 65,000 students locallyteachers locallyNow include grades Kinder through Algebra 2
4MAC Core Ideas TIMMS results 5 areas of emphasis Number Properties Number Operations (Mathematical Reasoning)AlgebraGeometryData and Statistics (Probability)This year test was designed to the new National Core Standards in Mathematics
5Why more tests?Difference between Standardized Tests and purposes and Performance Testing and purposesLearning from student workDeveloping meaningful feedback for students and teachers
6Goals of Assessment“We must ensure that tests measure what is of value, not just what is easy to test. If we want students to investigate, explore, and discover, assessment must not measure just mimicry mathematics.”Everybody CountsNotes on study in Australia. Correlation to STAR testing. Predicting goes only one way. False positive.
7Link Assessment and Learning “Assessment should be an integral part of teaching. It is the mechanism whereby teachers can learn how students think about mathematics as well as what students are able to accomplish.”Everybody Counts
8Purpose of ScoringGather data about student thinking to inform and improve instruction.Rubrics designed by international team to reflect shared values and perspectives.Rubrics provide one means of analyzing student work and giving teachers feedback.Scoring consistency allows us to capture data and gain insight into student thinking.
9You’re the District Ambassadors! Promote reliability and consistency.Provide opportunities for professional development in mathematics and reflections and insights for improving instruction.
10Leading Scoring is a difficult job. Phases of a Scoring SessionUnderstanding the AudienceResistanceSearch for evidenceIdeas for changing classroom instructionCare about studentsDesire for student successUncomfortable with the mathematicsChange from normal classroom practices
11Changing the Didactic Contract: For most teachers and students, this is changing what is fair or normal to ask in the classroom. This is no longer “business as usual”.Change is uncomfortable.
12What does it mean to understand a mathematical idea? Think of mathematics as a set of tools.Tool Possession?Tool Understanding?Tool Application?Tool Selection?
13What it means “to do” mathematics The Verbs of Mathematics: conjecture, solve, justify, represent, explain, describe, verify, use…Expanding the Didactic Contract - What is considered fair and reasonable in your classroom?
14Changing the Didactic Contract What is fair to ask in the classroom?Types of tasksTypes of task demandsWhat is needed to justify an answer?Different from curriculum specific tests/rather a check for transferenceOpportunity to show off what you know
15Didactic Contract Fred’s Flat Fred’s flat has five rooms. The total floor area is 60 sq. meters. Draw a plan of Fred’s flat. Label each room and show the dimensions (length and width of all rooms).Think about this task. What might your students do?
16America - country of lawyers, didactic contract what is the minimum that meets each word of the task.
17Australia - show thinking and how numbers are derived.
18Netherlands- show thinking and fit a real world context. Sweden - opportunity to show off what knowledge? Think of extensions or further exploration.
19Scoring Principles Different from other scoring systems Points are awarded throughout a task to emphasize varying aspects of doing mathematics“Is there more evidence of understanding or not understanding?”Mathematically equivalent expressions or alternative strategies get full credit.If you need to debate what the student was doing, the explanation was not complete.
20Task Design Entry level part - allow access Ramp up - not all parts are equalMeeting Standards - not based on percentage - so doesn’t meet that internal rubric of 90% AMeeting Standards based on professional judgment of National Board
21Rubrics Embody value judgments and explicit Computation and representationHow to tackle an unfamiliar problemInterpret and evaluate solutionsCommunicate results and reasoning to othersCarefully considered evaluation of performance
22Professional Development Opportunities to Learn Every square has two sides plus the two pieces at the end of the row:2X+2The end squares have three sides, middle squares have two sides: 2(X-2) + 6The right end square has three sides, middle squares have two sides and the right end square one extra piece: 2(X-1) + 4
23Take time to examine student work. Ask teachers to analyze student understandings and misconceptions.Think about what strategies helped students who were successful.What experiences do students need to help overcome the misconceptions?
24Reliability IssuesGreen Sheets - are participants consistent enough to start scoring real student workPost new solutions/solutions paths as they are discovered & other decisionsReliability checks within the sessionFirst foldersPeriodic spot checksRe-calibrate after breaks
25“Effective mathematics teaching requires understanding what students know and need to learn and then challenging and supporting them to learn it well.”“Assessment should support the learning of important mathematics and furnish useful information to both teachers and students.”NCTM Principles and Standards
26Scoring Norms Resist side conversations: The dilemma and making your own choice is part of the learning.When you talk over scoring with a neighbor the rest of us don’t benefit from your ideas or questions
27Scoring NormsWork task, then take a moment to write out the big mathematical ideas being assessed.When there is a question, everyone should take a moment of quiet think-time to see if you can find a reason for the official scoring decision. Then we will have an open discussion of the issue.
28Scoring Marks √ correct answer or comment x incorrect answer or comment√ft correct answer based upon previousincorrect answer called a follow through^ correct but incomplete work - no credit( ) points awarded for partial credit.m.r student misread the item. Must notlower the demands of the task -1 deduction
29The PartyDarren and Cindy are planning a party for their friends. They have 9 friends coming to the party. How many people will be at the party? ____________.They are buying cupcakes and cans of soda. Cupcakes cost $1.50 and soda costs 75¢. How much does it cost for each person? __________.Show how you figured it out.3. How much will it cost for everyone to have a cupcake and soda? ________________.4. They just remembered to buy a 50¢ party bag for each friend. Show how to find the total cost for the party.
