This will take about 30 minutes.

4. Subject Matter Expert/Author: Assoc. Prof. Dr Rashid Johar (OUM) Faculty of Science and Foundation Studies Copyright © ODL Jan 2005 Open University Malaysia UNIT 1: INTRODUCTION TO MEASUREMENT and EVALUATION in SCIENCE Chapter one exposes learners to the key terms and definitions. Chapter two discusses about the selection and writing of instructional objectives as platform to construct test blueprint. Chapter three discusses the concepts of validity and reliability as criteria for good measuring instruments.

5. Subject Matter Expert/Author: Assoc. Prof. Dr Rashid Johar (OUM) Faculty of Science and Foundation Studies Copyright © ODL Jan 2005 Open University Malaysia Terms and definitions TESTING refers to the procedure or use of any device to evaluate the behaviour or performance of a person. Many aspects of behaviour can be tested: cognitive, affective and psychomotor. A part of the whole behaviour is tested. What type of test to use would depend on the purpose of testing. It should be planned before administering the test.

6. Subject Matter Expert/Author: Assoc. Prof. Dr Rashid Johar (OUM) Faculty of Science and Foundation Studies Copyright © ODL Jan 2005 Open University Malaysia MEASUREMENT Measurement refers to the process of quantifying assessment data. It is the process of collecting and gathering information. It is a quantifying procedure for determining or indexing the amount or quantity of some construct or entity. It also refers to the assignment of numbers to objects or events. It is used to describe student performance and characteristics. It provides information for decision making. Measurement scales: nominal, ordinal, interval and ratio.

7. Subject Matter Expert/Author: Assoc. Prof. Dr Rashid Johar (OUM) Faculty of Science and Foundation Studies Copyright © ODL Jan 2005 Open University Malaysia EVALUATION OR ASSESSMENT EVALUATION refers to the process of making judgment of the merit or value of a person, object or programmme from a composite of test scores, observations and reports. It is the process of data gathering to make judgment and decision making about students performance and programme. It is a process of comparing students’ performance or characteristics against a predetermined standard or criterion thought to indicate mastery. Evaluation can de conducted as formative or summative depending on the phase and purpose of evaluation.

8. Subject Matter Expert/Author: Assoc. Prof. Dr Rashid Johar (OUM) Faculty of Science and Foundation Studies Copyright © ODL Jan 2005 Open University Malaysia EVALUATION OR ASSESSMENT ASSESSMENT refers to those activities that are designed to measure learner achievement brought about as a result of an instructional programme of some sort. It is a procedure used to evaluate an individual so that one can describe the person in terms of current functioning and can also predict future functioning.

9. Subject Matter Expert/Author: Assoc. Prof. Dr Rashid Johar (OUM) Faculty of Science and Foundation Studies Copyright © ODL Jan 2005 Open University Malaysia Criterion referenced evaluation This type of evaluation compares the performances of pupils to a standard criterion of performance. The individual pupil is compared to a predetermined standard. Or to the criterion of a certain standard of performances of other groups of similar age, background and experience.

10. Subject Matter Expert/Author: Assoc. Prof. Dr Rashid Johar (OUM) Faculty of Science and Foundation Studies Copyright © ODL Jan 2005 Open University Malaysia Norm referenced evaluation This type of evaluation compares the relative performances of pupils.  The individual pupil is compared to: the performances of pupils within the group being tested Or  the performances of other pupils of similar age, background and experience.

11. Subject Matter Expert/Author: Assoc. Prof. Dr Rashid Johar (OUM) Faculty of Science and Foundation Studies Copyright © ODL Jan 2005 Open University Malaysia Formative evaluation This type of evaluation is carried out during a programme of instruction. It provides the learners with feedback on how they are doing in class so far. It provides the teachers with information on the suitability of learning activities and materials. Discussion: students are required to read the research literature on this topic for their assignment.

12. Subject Matter Expert/Author: Assoc. Prof. Dr Rashid Johar (OUM) Faculty of Science and Foundation Studies Copyright © ODL Jan 2005 Open University Malaysia SUMMATIVE EVALUATION Summative evaluation  This type of evaluation is carried out at the end of a programme of instruction.  It is used to evaluate or make judgment of the merit or value of the programmme. Discussion: students are required to read the research literature on this topic for their assignment.

13. Subject Matter Expert/Author: Assoc. Prof. Dr Rashid Johar (OUM) Faculty of Science and Foundation Studies Copyright © ODL Jan 2005 Open University Malaysia Why we evaluate our science students PRIMARY REASONS: To provide information regarding how effective the teaching procedures, learning activities and materials so that teacher can modify and plan instruction best for the pupils. To identify pupils who are lacking in prerequisite knowledge and skills so that proper materials and activities can be provided to improve student learning. Discussion: use examples of science lesson, activities and materials.

14. Subject Matter Expert/Author: Assoc. Prof. Dr Rashid Johar (OUM) Faculty of Science and Foundation Studies Copyright © ODL Jan 2005 Open University Malaysia Further Primary Reasons: To provide feedback to pupils on their learning progress to determine if and when they have mastered the subject matter. To assess pupils’ understanding towards the learning programme and relate the next plan of teaching with the pupils’ acquired knowledge and skills. Discussion: use examples of science/chemistry/ biology/physics lessons, activities and materials.

15. Subject Matter Expert/Author: Assoc. Prof. Dr Rashid Johar (OUM) Faculty of Science and Foundation Studies Copyright © ODL Jan 2005 Open University Malaysia SECONDARY REASONS: To grade students To place students To conduct research Discussion: use examples of science/chemistry/ biology/physics lessons, activities and materials.

16. Subject Matter Expert/Author: Assoc. Prof. Dr Rashid Johar (OUM) Faculty of Science and Foundation Studies Copyright © ODL Jan 2005 Open University Malaysia QUICK CHECK ON YOUR UNDERSTANDING Which of the following would you considered measurement rather than evaluation? A. Ali got 70 out 80 in Science. B. Maria is poor in Chemistry. C. She got grade B for Physics. D. He got 65% correct in Biology test.

17. Subject Matter Expert/Author: Assoc. Prof. Dr Rashid Johar (OUM) Faculty of Science and Foundation Studies Copyright © ODL Jan 2005 Open University Malaysia Measuring Learning Outcomes Distinguish between educational goals, educational objectives and learning objectives in science. Differentiate between behavioural objectives and expressive objectives. Instructional objectives or learning objectives of science lessons. Pg 22-23
