A Quantitative Literacy Assessment Rubric Development & Lessons Learned - Stuart Boersma, Central Washington Univ. - Caren Diefenderfer, Hollins University - Shannon Dingman, Univ. of Arkansas - Bernie Madison, Univ. of Arkansas Supported by the National Science Foundation DUE-0715039 Numeracy Article: Quantitative Reasoning in the Contemporary World 3: Assessing Student Learning http://services.bepress.com/numeracy/ Our Course • Uses case studies centered on one or more media articles • Each case study contains study questions focusing on the quantitative content of the article • Student responses often involve critiquing, analyzing, decision making, and explaining.

Need: Instrument that we could apply to these non-standard student responses. A Little History AAC&U VALUE Project: •Developed for institutional level assessment (not for grading student work) •15 areas, 10 of which are termed Intellectual and Practical skills: •Inquiry and analysis, critical thinking, written communication, oral communication, reading, quantitative literacy, information literacy, teamwork, problem solving Interpretation Representation Calculation Application/Analysis Assumptions Communication Alignment of QL VALUE Rubric w/ QRCW course Missing Competencies?: – Critical Reading – Number sense – Synthesis Folded into “Interpretation” Changed “application/analysis” to “analysis/synthesis” Scale – No “zero” – “4” designated capstone achievement; not a consideration for student work in a QL course New Scale: 0-3 Achievement Level Quantitative Literacy Core Competency Interpretation Ability to glean and explain mathematical information presented in various forms (e.g. equations, graphs, diagrams, tables, words) Representation Ability to convert information from one mathematical form (e.g. equations, graphs, diagrams, tables, words) into another. Calculation Ability to perform arithmetical and mathematical calculations. 3 2 1 0 Correctly identifies all relevant information. Correctly identifies some, but not all, relevant information. Some relevant information is identified, but none is correct. No relevant information identified. All relevant conversions are present and correct. Some correct and relevant conversions are present but some conversions are incorrect or not present. Some information is converted, but it is irrelevant or incorrect. No conversion is attempted. Calculations related to the problem are correct and lead to a successful completion of the problem. Calculations related to the problem are attempted but either contain errors or are not complete enough to solve the problem. Calculations related to the problem are attempted but contain errors and are not complete enough to solve the problem. Calculations given are not related to the problem, or no work is present. Analysis/Synthesis Ability to make and draw conclusions based on quantitative analysis. Uses correct and complete quantitative analysis to make relevant and correct conclusions. Assumptions Ability to make and evaluate important assumptions in estimation, modeling, and data analysis. All assumptions needed are present and justified when necessary. Communication Ability to explain thoughts and processes in terms of what evidence is used, how it is organized, presented, and A correct and complete explanation is clearly presented. Quantitative analysis is given to support a relevant conclusion but it is either An incorrect quantitative only partially correct or analysis is given to support a partially complete (e.g. there conclusion. are logical errors or unsubstantiated claims). At least one correct and relevant assumption is given Attempts to describe (perhaps coupled with assumptions, but none of the erroneous assumptions), yet assumptions described are some important assumptions relevant. are not present. A partially correct relevant explanation is present, but incomplete or poorly presented. A relevant explanation is present, but is illogical, incorrect, illegible, or incoherent. Either no reasonable conclusion is made or, if present, is not based on quantitative analysis. No assumptions present. No relevant explanation is provided.

Allows one to align student prompts with an organized thought process as represented by the rubric To solve a complex problem a student needs to read and glean information, convert the information into a usable form, calculate, make or draw a conclusion, and then communicate the result via explanation. Scaffold student learning by sorting case Students often do not recognize these as components of studiesresponse. by competency: with through mastery of a strong GuidingStart students Interpretation & Representation and build up these competencies is crucial! to more complex prompts.
