Measurements, Assessment and Evaluation in Outcome- Based education the quantities and qualities of interest are abstract. hot. Such instruments maybe ruler. voluminous. we are actually collecting quantitative information relative to some established standards. In the field of education. cold. fast. Sometimes. and straight some things are. When we measure we measure. to find the area of rectangular piece of paper. we use some standards instrument to find out how long. . we can measure physical quantities by combining directly measurable quantities to form derived quantities. for example. unseen and cannot be touched and so the measurement process become difficult. heavy.Measurement Measurement is the process of determining or describing the attributes or characteristic of physical objects generally in terms of quantity. hence the need to specify the learning outcomes to be measured. we simply multiply the lengths of sides of paper. When we measure. however. thermometer or pressure gauge. scale. The same concept can be measured in onother way. In this case the measurement procedure is testing. knowledge of the subject matter is measured through perceptions. .• For instance. In this procedure. We can ask group of expert to rate students knowledge of subject matter in the scale of 1 to 5 with 1 being the lowest and 5 being the highest. knowledge of the subject matter is often measured through standardize test results. 2 Types of Measurements •Objective •Subjective . that is with out bias or prejudice. thermometer .Objective Measurements • Objective Measures involves an impartial measurements. It includes standards instrument like ruler. biameasuring devices. scale etc. it is not subject to personal opinion or interpretation of results. . These measures are often criticized as they are open to interpretation and opinion. It is often refer to the quality and style of the performance.Subjective Measurements • Subjective measurements are influenced by the observer’s personal judgment of how a particular skill was performed. . Exercises: Objective or Subjective ? . • Participants reported how often they watched television per week. SUBJECTIVE . OBJECTIVE .• Researcher measured the number of hours children watched television per week. • College students reported the number of hours they studied per week SUBJECTIVE . OBJECTIVE .• Researcher measured the heart rate of students watching horror movie. • Researcher measured the number of pounds students lost after running 3 times a week for 1 month. OBJECTIVE . • Assessment requires review of journal entries. presentation. journals.Assessment • Assessment is the process of gathering evidences of student’s performance over period of time to determine learning and mastery of skills. story written. written work. test and other learning tasks. test result. portfolio. Such evidence of learning can take the forms of dialogue record. research paper. written work . etc. essays. . we expect our process to give information regarding the worth. goodness. appropriateness. reject or revise what has been evaluated . or legality of something for which a reliable measurement has been made • Evaluation is a process to designed to provide information thet would help us to make a judgment about a particular situation • The end result of evaluation is to adopt. validity.Evaluation • Evaluation originates from the rootword “Value” and so when we evaluate.
