Assessment: Constructing and Evaluating

Based from the behavioural educational theories, higher learning institutions has been using assessment to measure the quality or success of a taught course and to evaluate whether the students have achieved (Ellery, 2008) the minimum standard that is acceptable to be awarded with the degree. An assessment can be conducted by means of paper and pencil, presentations, lab work, case studies, essays, multiple choice questions, true/false statements, short essays, etc. During the semester, students may be tested to improve their learning experience; this is called a formative test (continuous assessment), whereas a summative test (final assessment) is done at the end or completion of the course or program. A test can be used to measure students' ability or to determine the basic mastery or skills or competencies acquired during a course. There are several types of tests; such as, placement test, diagnostic test, progress test, achievement test, and aptitude test. A placement test is done to place students in teaching groups or classes so that they are within the same level of ability or competency. A diagnostic test is done to identify students' strengths and weaknesses in a particular course. A progress test is done during the semester to measure the progress of students in acquiring the subject taught. An achievement test is done to determine students' mastery of a particular subject at the end of the semester. Whereas an aptitude test is done to determine the students' ability to learn new skills or the potential to succeed in a particular academic program. A good assessment should be valid, reliable, and practical. In terms of validity, an assessment should test what it is intended to measure. For example, content validity is when the test items adequately cover the syllabus. A valid assessment measures achievement of the course learning outcomes. In terms of reliability, does the assessment allow the examiners to evaluate it consistently and differentiate between varying levels of performance? Whereas in terms of practicality, we need to ensure that the length given to students for their assessments are appropriate. There are two types of tests, objective and subjective. For objective, we can choose multiple choice questions, true/false, or fill in the blanks; whereas for subjective we can choose either short or long essay. Although there are objective and subjective tests, I would like to focus on subjective test (essays) because we use this type most often; especially in final exam. When constructing an assessment, we need to bear in mind the objectives of learning of a particular course. Specifically, we need to refer to the course information of the course learning outcomes before constructing the exam questions. In addition, we need to understand Bloom's Taxonomy or classifications of objectives. The three classifications are cognitive, affective, and psychomotor. The six levels of cognitive domain are knowledge, comprehension, application, analysis, synthesis, and evaluation. The levels for affective domain are receiving, responding, valuing, organizing, and characterizing. Psychomotor levels are imitation, manipulation, precision, articulation, and naturalization. I have discussed in detail about the levels of each domain in the previous issue; thus, in this issue I would like to discuss on cognitive domain because this is the most frequently used in final exam and we are quite familiar with it.
