Lunday 05JUL12 FDW Joint Session on Holistic Grading COL Alex Heidenberg 05JUL12 Common Assessment Mechanisms FDW • Course-wide – – – – • Instructor-specific WPRs (Exams) TEEs (Finals) Projects Course-specific topical exams (FCE, FDE, FIE…) Graded Event Sample point allocation (MA104) – – – – – Quizzes Homework Presentations Class preparation Subjective grade* • 10% of instructor points • Think twice before doing this at all. Are you assessing understanding or rewarding extroversion (or mimicry)? Points Instructor Points 150 FDE 60 WPRs (3) 390 Project 100 CCE 50 TEE 250 Total 1000 Slide 4 FDW What are the purposes for grading student work? FDW What is holistic grading? Determination of the overall quality of a piece of work or an endeavor by considering various aspects or components of the work without marking or tallying them. Education.com What are the advantages and disadvantages of holistic grading FDW Discussion • What are some advantages to holistic grading? – Analytic rubrics can be too prescriptive (in either direction) – Allows time to focus on feedback/comments (quick) • What are some disadvantages to holistic grading? – Accepts a certain level of imprecision • What are some caveats…? – Must communicate standards – Calibration still necessary 7 FDW Accuracy vs. Precision • What is the difference between accuracy and precision? • What does this mean with respect to grading? 8 FDW Math Department Grading Guidelines FDW SUBJECTIVE INTERPRETATION LETTER GRADE Beyond expectations of the course A+ 4.33 Dominates the material A 4 Mastery A- 3.67 Excellent performance B+ 3.33 Good understanding B 3 Proficient; Aptitude for the subject B- 2.67 Can build upon this foundation C+ 2.33 Passing; Proficient now (short range) C 2 Short-range understanding C- 1.67 D 1 F 0 Marginal performance with some elementary understanding Failing; Definitely failed to demonstrate understanding NUMERICAL GRADE QUALITY POINT 10 FDW You still need a rubric… 11 FDW A rubric • A scoring guide to evaluate a student’s performance based on established criteria. • Chocolate Chip Cookie Rubric – Chips – Texture – Color – Taste – Flavor 12 FDW A rubric 4- Delicious Chip in every bite, chewy, golden brown, rich, creamy, highfat flavor 3 – Good 75% bites have chips, chewy in the middle, but crisp on edges, a little too brown or undercooked Store bought quality, medium fat content 2 – Needs Improvement 50% bites have chips, too crispy or too under cooked, tasteless, low-fat content 1- Poor Too few chips, texture resembles dog biscuit, burned, chalky non-fat contents 13 FDW A rubric in the making • Focused holistic grading – Work exceeds standard, meets the required standard, – falls just short of the standard, does not meet the standard • Analytic holistic grading – Divided by performance area – Correctness, organization, style, substance • Major , Minor Errors 14 FDW Description Problem-specific Holistic Rubric MA104 WPR#3, 2012 For this problem Grade Points Correct answer w/supporting work & correct units of measurement. A+ 30 Minor calculation/unit error. A 28 Finds critical point but doesn’t classify it; answers final question correctly. B 25 Passing; proficient now Finds critical point. C 22 Marginal performance Takes first-partial derivatives correctly. D 20 Struggles with the right concept. High F 18 No concepts correct, despite related work Low F 8 No work of value No value 0 Exceeds course expectations (no mistakes) Dominates the material Good understanding Failing; definitely failed to demonstrate understanding Sample procedure within MA104 • For A, B, or C-level work, instructor identifies the mistake(s) for the student • For D or F-level work, instructor also refers the student to the text for a similar problem, such as “See Example #4, pg. 948.” in order to help the cadet remediate conceptual or procedural gaps. Caveat • Cadets often solve (or approximate solutions to) problems in unexpected and completely valid ways! Keep your eyes (and your mind) open!! 15 FDW Questions? * Caution: don’t confuse humor with beliefs. 16 Generic Holistic Rubric USAFA Math Department, 2009 FDW Well-executed • Applies a strategy that makes sense for the given question • Applies appropriate mathematical concepts and processes • Does not introduce superfluous material • Technology is used appropriately • Work is logical and includes a sanity check of the final answer Well-communicated • Readable: Work stands alone (retains context) and is neat and professional in appearance • Organized: Provides a clear logical flow form beginning to end • Provides sufficient supporting detail and explanation throughout • Work is free from grammatical errors • Mathematical composition, terminology, and notation is correct • Results and/or conclusions are clearly annotated Essentially Correct • Precision: Performs mathematical operations correctly and derives the correct results • Uses an appropriate degree of accuracy • Draws correct inferences from graphical or numerical data • Any computational or algebraic errors are trivial and isolated • Correct units are used 5 4 3 2 1 Outstanding (“A”) Good (“B”) Average (“C”) Deficient (“D”) Failing (“F”) Well-executed, wellcommunicated, essentially correct Generally wellexecuted but may have minor communication flaws or some math errors Adequately executed but with some non-trivial errors or inconsistent communication Flawed execution possibly with nontrivial errors or poor communication Unsatisfactory execution and/or communication with fundamental errors Slide 17
