Evaluation ii

  1. 1. Evaluation Part II
  2. 2. Objectives ● Evaluation process ● Types of evaluation ● Criteria for selection of evaluation techniques
  3. 3. Evaluation process/ Steps in Evaluation Steps in evaluation process are 1. Identifying the purpose of evaluation 2. Identifying the time frame 3. Determining when to evaluate 4. Selecting the evaluators 5. Choosing an evaluation framework/design or model
  4. 4. 6.Selecting evaluation instrument 7.Collecting data 8. Interpret the data 9. Report the findings 10.Using the finding 11. Considering the cost of effectiveness
  5. 5. Types of Evaluation
  6. 6. Types/Classification Evaluation can be classified in many ways ● Based on frequency ● Based on nature of measurement ● Based on methods of interpreting results
  7. 7. Based on frequency Formative Evaluation: It is used to monitor learning process during instruction and to provide continuous feedback to both student and teacher regarding the learning process. ❖ It reinforce learning in students ❖ It identifies teaching and learning errors ❖ Provides feedback to the teachers regarding their method ❖ The results obtained are not used for assigning course grades
  8. 8. Summative Evaluation It is a evaluation done at the end of a course or unit of instruction. It is designed to identify to what extent the instructional objectives are met. The main purpose of this evaluation is for grading and certification of students. It also provide information for judging the course and curriculum content.
  9. 9. Based on the nature of measurement Maximum Performance Evaluation: In this type of evaluation the performance of the students are measured to know the person’s maximum ability and to check their motivation toward the course. Aptitude and achievement tests are used in this type of evaluation Typical Performance Evaluation: In this type the Evaluation is done under natural setting ie. the assessment of their typical behaviour. Personality tests and observation techniques are used as evaluation tool
  10. 10. Based on method of interpretation Criterion-referenced Evaluation: In this evaluation the student’s performance will be compared to a set criteria which is expected as learning outcome. Here the students are evaluated without comparison. Eg. Student skill of giving IM injection compared with a checklist Norm-referenced Evaluation This type of evaluation describes the students performance according to relative position in some known group. This is usually used to rank them in local, state or central level.
  11. 11. Difference between Formative Evaluation ● Monitor progress of student ● Detailed content ● Narrow scope ● Tools used are daily assignments and class tests ● More frequently conducted Summative Evaluation ● Check final status of the students ● General content ● Broad scope ● Tools used are Projects, Examinations ● Less frequently conducted
  12. 12. Criteria for selecting appropriate Evaluation technique ➢ Validity ➢ Reliability ➢ Objectivity ➢ Practicability ➢ Relevance ➢ Specificity
  13. 13. Validity It means the extent to which a test measures what it is intended to measure. Types of Validity ● Face validity ● Content validity ● Construct validity ● Criterion based validity
  14. 14. Reliability Reliability refers to the extent to which an assessment method or instrument measures consistently the performance of the student. Methods ● Test retest method ● Split half method
  15. 15. Objectivity It is the degree of consensus with which two or more evaluators score the same test. Practicability and Feasibility It includes various factors like, Teacher’s knowledge and experience on administration of the tool, Time ,Money and other resources.
  16. 16. Relevance It is the appropriateness of the tool to evaluate what it supposed to be evaluated Specificity The tool and the items listed in that should be related to the educational objectives
  17. 17. Summary ● Steps in evaluation ● Types of evaluation ● Criteria for selecting evaluation tool
