1. Determining Grades created for ETR 430 by Lisa M. Mehlig COE/NIU

2. I’ve measured, so now what? Scales Criterion-referenced Consistent band-width distribution on a percentage scale  Standard Scale  Adjusted Scale Curves Norm-referenced Based on a distribution of scores  Normal Curve  Visual Inspection Method (Sculpted Curve/Gap Method)

3. What to record in grade book? Letter grades Percentage correct Raw scores Pass/fail Checklist Descriptions

4. What is the purpose of grades? Keep students informed Keep parents informed Administrative purposes Class rank, graduation, honors, athletic eligibility, transcripts Guidance purposes Vocational choices, college choices, identify potential personal problems

5. Determining Report Card Grades Select what to include in the final grade Tests, papers, projects, assignments, homework, participation, effort, improvement Consider overall learning goals Select weights for each assessment Combine weighted scores to determine a single grade

6. Methods of Determining Report Card Grades Eyeball Method Lacks objectivity Address the whole over each part Recognizes need for teacher professional judgment in giving grades

7. Methods of Determining Report Card Grades Total Points Method Based on recorded raw data Add total points for all relevant assessments to get total Points can be assigned to determine weight of assessment Compare total points to a predetermined scale

8. Methods of Determining Report Card Grades Percent Correct Method Demonstrates a level of objectivity Convert each score or grade to the same scale (percentage) Weighted Method Based on criteria (objectives or assessments) Calculate a percentage for each criteria Multiply the percentage by the pre-determined weight Sum the products of each for overall grade

9. Sample Calculation of Weighted Grades from Grading Activity STEP 1: Determine which assessments fit into which weighted criteria Writing  Persuasive Essay and Revision  Research, Research Paper Draft 1 and Revision Book Report Novel  Novel Questions  Novel Vocab.  Novel Quiz

10. STEP 1: Sum Total Points and Student’s Points for each weighted criteria Sample Calculation of Weighted Grades from Grading Activity WritingBook ReportNovel Total Points Student X Total Points Student X Total Points Student X 50 30 15 20 35 150 42 26 11 15 29 123 20 40 15 17 32 20 15 20 15 35 105 16 15 20 14 33 98

11. Sample Calculation of Weighted Grades from Grading Activity STEP 2: Calculate a percentage for each weighted criteria For each criteria, divide Student’s Points by Total Points Writing Total Points Student X 50 30 15 20 35 150 42 26 11 15 29 123 For the Writing criteria: 123/150 =.82 Do this for all criteria Book Report = 32/40 =.80 Novel = 98/105 =.933

12. Sample Calculation of Weighted Grades from Grading Activity STEP 3: Multiply percentage for each weighted criteria times the weighting percentage Mr. White’s Weights for Each Criteria Writing – 45% Book Report – 15% Novel – 40% Writing =.82 X.45 =.369 Book Reports =.80 X.15 =.120 Novel =.933 X.40 =.373 Criteria Percentage From Previous Calculation

13. Sample Calculation of Weighted Grades from Grading Activity Sum all the products to determine overall grade may multiply by 100% if easier to interpret compare against scale Writing =.82 X.45 =.369 Book Reports =.80 X.15 =.120 Novel =.933 X.40 =.373.862.862 x 100% = 88.2% Using a Standard Scale, Student X earns a B.
