14 - DEFINITION, TYPES OF ASSESSMENTS, AND QUALITIES OF A GOOD MEASURING INSTRUMENT Flashcards
- Determines the desired dimensions of defined characteristics
- Involves the quantitative amount of measurement using measuring scales: ruler for length, weighing scale for weight, thermometer for temperature
- Characteristics: reliability, validity, and objectivity
Measurement
- Measures the performance of an individual from a known objective or goal
- Gaining information on the students’ extent of learning and organizes the data gathered into interpretable forms of variables in numbers
- Includes tests, aptitude tests, inventories, and questionnaires
Assessment
- Gives value judgment to assessment through the qualitative measure of the prevailing situation
- Determines the appropriateness, worthiness, goodness, validity, and legality of something based on predetermined standards
Evaluation
- Does not express any clear assumption about a student
- Does not require much energy and time
- The scope is limited, only some dimensions of personality can be tested under measurement
- It is content-oriented
- It is a means and not an end in itself
- The purpose is to gather evidence
- It may not be an essential part of education
- Answers the question “how much” (measurement)
- Prediction cannot be made meaningfully based on measurement
- It acquaints with a situation. This is isolated from the entire environment
- It indicates those observations which are displayed numerically
- It can be conducted at any time
Measurement
- The clear assumption about a student can be formed
- Requires more energy and time
- The scope is wide; in it, the entire personality of a student is tested
- It is objective-oriented
- It is an end in itself
- It deduces inferences from the evidence, that is, its work is appraisement of evidence
- It is an integrated or necessary part of education
- Answers the question “what value”
- It can predict meaningfully
- It acquaints about the entire situation
- It comprises both quantitative and qualitative observations
- It is a continuous process
Evaluation
Assessments that complement each other to determine the totality of the students’ performances. Either of the two can be used for the improvement and enhancement of teaching.
Formal & Informal
- Data-based test
- Determines students’ proficiency or mastery of the content or knowledge testing
- Systematic
- Structured
- Used for comparison against a certain standard
- Mathematically computed and summarized (formal grading system)
- Assesses overall achievement
- Norm-referenced measure
- Quantitative
- Normal classroom environment
- Examples: exams, diagnostic tests, achievement tests, aptitude tests, intelligence tests, and quizzes
Formal Assessment
- Content and performance-driven
- Measures students’ performance and progress (progress measuring)
- Spontaneous
- Flexible
- Progress of every student by using actual works (individualized)
- The rubric score is used
- Day-to-day activities such as projects, assignments, experiments, and demonstration
- Criterion-referenced measure
- Qualitative
- Could be beyond the classroom environment
- Examples: checklists, observations, portfolio, rating scale, records, interviews, and journal writing
Informal Assessment
Assessments can be categorized according to the nature of the content and various functions. Both types are essential components of classroom instruction.
Formative & Summative
- Determines whether learning is taking place
- Provides feedback on how things are going and it is used to emphasize areas for further studies
- Helps students perform well at the end of the program or monitors the students’ progress
- It is a gathering of detailed information and narrow in the scope of the content
- Evaluates the effectiveness and improvement of teaching
- Conducted during teaching or instruction daily or every session
- Primarily prospective
- Examples: observation, oral questioning, assignments, quizzes, discussions, reflection, research proposal, peer or self-assessment
Formative Assessment
- Determines if learning is sufficiently complete
- Determines how well things went measures students’ overall performances
- Concerned with purposes, progress, and outcomes of the teaching-learning process
- Gathering information is less detailed but broader in the scope of content or skills assessed
- Provides information to the students, parents, and administrators on the level of accomplishment attained
- Occurs at the end of the instruction on the end of each unit
- Primarily retrospective
- Examples: unit test, final examinations, comprehensive projects, research paper, presentations, project, and portfolio
Summative Assessment
Used to interpret student performance. The test score of a student could be compared among the class standing or compare based on standardizing criteria.v
Norm-referenced & Criterion-referenced
- It is a relative ranking of students
- Students compete against each other
- Determines the students’ placement on a normal distribution curve to rank and sort students
- Determines a student’s level of the construct measured by a test concerning a well-defined reference group of students
- Examinee-centered
- Evaluates the effectiveness of the teaching program and student’s preparedness for the program
- Focuses too heavily on memorization and routine procedure
- Highlights achievement differences
- Identifies whether a particular student performs better or worse than the rest of the students
- Statistical methods used on how raw scores are interpreted such as the percentile rank, and normal curve
- NSAT, College Entrance Examinations, National Achievement Test, IQ Test, and Cognitive Ability Test
Norm-referenced Assessment
- It interprets scores in terms of absolute standard
- A student competes against him/herself
- Measures how well students have mastered a particular body of knowledge
- Determines a student’s level of performance about a well-defined domain of content
- Content-centered
- Assesses higher-level thinking and writing skills
- Emphasizes thinking and application of knowledge
- Setting performance standards
- Used to monitor students’ performance in their day-to-day activities
- Tests must be valid and reliable. Test item analysis
- Domain-referenced tests, competency tests, basic skills tests, mastery tests, performance or assessments, objective-referenced tests, authentic assessments, and standards-based tests
