  2. 2. Critical questions• What is the purpose do grades serve?• What is the trouble with evaluation of students?• How to make grading more effecient?
  3. 3. Definition of grading• Grades in the realm of education are standardized measurements of varying levels of comprehension within a subject area.• Grades can be assigned in letters (for example, A, B, C, D, or E, or F), as a range (for example 4.0–1.0), as a number out of a possible total (for example out of 20 or 100), as descriptors (excellent, great, satisfactory, needs improvement).
  4. 4. Philosophy of GradingBase grades on student achievement, and achievement only.Grades should represent the extent to which the intendedlearning outcomes were achieved by students. They should notbe contaminated by student effort, tardiness, misbehavior, andother extraneous factors. . . . If they are permitted to becomepart of the grade, the meaning of the grade as an indicator ofachievement is lost.Gronlund (1998) (pp. 174-175)

  7. 7. Some Principles and Guidelines for Grading and EvaluationPrinciples• Grading is not necessarily based on a universally acceptedscale.• Grading is sometimes subjective and context- dependant.• Grades may not “mean” the same thing to all people.• Alternatives to letter or numerical grades are highly desirable as additionalindicators of achievement.
  8. 8. Some Principles and Guidelines for Grading and EvaluationGuideline1. Develop an informed, comprehensive personal philosophy of grading that isconsistent with your philosophy of teaching and evaluation.2. Design tests that conform to appropriate institutional and cultural expectations of the difficulty that students should experience.3. Select appropriate criteria for grading and their relative weighting in calculatinggrades.4. Communicate criteria for grading to students at the beginning of the course and atsubsequent grading periods (mid-term, final)5.Triangulate formal graded evaluations with alternatives that are more formativeand that give more washback.
  9. 9. What is the purpose do grades serve?
  10. 10. What is the purpose do grades serve?Barbara Walvoord and Virginia Anderson identify the multiple roles that grades serve:• as an evaluation of student work;• as a means of communicating to students, parents, graduate schools, professional schools, and future employers about a student’s performance in college and potential for further success;• as a source of motivation to students for continued learning and improvement;• as a means of organizing a lesson, a unit, or a semester in that grades mark transitions in a course and bring closure to it.
  11. 11. What is the trouble with evaluation of students?
  12. 12. What is the trouble with evaluation of students?Suskie identify some problems with student evaluation :• Evaluation is a highly inconsistent process. Teachers give different numbers and types of assessments and weight them differently.• There is disagreement on issues like the role and value of work. Some teachers assign homework frequently and weight it heavily, while some don’t assign it at all.• Some teachers will allow retakes of tests and quizzes, others do not.
  13. 13. What is the trouble with evaluation of students?• Different policies exist for work turned in late.• Districts may or require different final grades as a passing mark -– 60 to 70 is a common but large range.• Districts may set a minimum score that teachers can record – e.g., no grade lower than a 50 is allowed.• The validity and reliability of student assessments vary.• There are major philosophical differences regarding evaluation. Some teachers view learning as primarily a student responsibility, while some place the responsibility for teaching mainly on themselves.
  14. 14. What is the trouble with evaluation of students?• There is little agreement on many assessments and what kinds are needed for evaluation.• Even within the same school different teachers teach differently and test differently for the same course.
  15. 15. How to make grading more effecient?
  16. 16. How to make grading more effecient?There are some strategies that we can use to make the grading process more efficient. At the very beginning Consider the course grading policies. Before you grade Try creating a rubric, or grading scale, and test it out on a sampling of papers. While you are grading Grade while you are in a good mood. Commenting on Student Work Identify common problems students had with an assignment and prepare a handout addressing those problems. After You’ve Graded If appropriate for your course or section, use a spreadsheet or the Space Grading feature to calculate grades.
