Measurement and Evaluation Lecture Notes Flashcards

A comprehensive set of vocabulary flashcards covering measurement concepts, types of tests, evaluation standards, and statistical analysis based on the lecture notes provided.

Education (Generic Definition)

The transmission of knowledge, skills and attitudes from one person to another, or the process by which people are prepared to live effectively in their environment.

Chinese Context of Testing

Civil-service testing that began about 3000 years ago, where emperors examined officials every third year to promote or dismiss them.

Sir Francis Galton (1822-1911)

An experimental psychologist in Great Britain who first looked into psychological differences (nature and nurture) and applied statistical methods like correlation and regression.

Alfred Binet (1871-1938)

Developed the first individual tests of intelligence in 1905, using the formula $\frac{M.A}{C.A} \times 100$ to identify children not benefitting from school.

Test

A device used to sample the behavior or performance of a candidate or student.

Achievement Tests

Tests that measure the current status of learners with respect to proficiency in a given area of knowledge or skill, such as KCPE and KCSE.

Aptitude Tests

Standardized measures of potential used to predict how well someone is likely to perform in the future.

Standardized Test

A test developed by specialists, administered and interpreted using uniform procedures and performance standards.

Assessment

The systematic collection and analysis of information to improve student learning and determine acquisition of course outcomes.

Evaluation

The ability to make a judgment on the worthiness of a programme, project, or course on the basis of given information.

Measurement

The act of assigning numbers or symbols to characteristics of objects, people, or events according to specific rules.

Independent Variable

The variable that causes change in another, such as school type or parental income.

Intervening Variable

A variable that comes between the independent and dependent variables, such as home chores.

Nominal Scale

The simplest form of measurement where numbers or labels are used to substitute for names to classify objects into mutually exclusive categories.

Ordinal Scale

A measurement scale that permits classification and rank-ordering based on magnitude, but has no absolute zero point.

Interval Scale

A numeric scale where the exact distance between categories is known and equal, but the zero point is arbitrary (e.g., Temperature in $^{\circ}C$).

Ratio Scale

A measurement scale with all properties of nominal, ordinal, and interval scales plus a true or absolute zero point (e.g., weight, height, income).

Placement

The use of tests to group students into homogenous classes according to their abilities for maximum teaching efficiency.

Diagnosis

The use of tests to isolate specific learning difficulties or deficiencies, such as identifying dyslexia.

Halo Effect

A consistent bias occurring when an examiner's general impression of a candidate (based on ethnicity, gender, etc.) influences their scoring.

Self-fulfilling Prophecy

A situation where a teacher's false belief or expectation about a student's ability eventually creates its own reality in the student's performance.

Leniency/Severity Errors

Consistent errors where examiners give ratings that are either too high or too low.

Error of Central Tendency

The tendency of some examiners to avoid extreme scores, concentrating instead around the midpoint or average of the scale.

KNEC

The Kenya National Examinations Council, legally mandated to conduct school examinations, issue certificates, and ensure examination security.

Item Banking

The storage of test items for future use, beneficial for curriculum stability and in cases where mass leakage requires exam cancellation.

Positive Skewness

A distribution where most candidates achieve low scores, as seen in the 2016 and 2017 KCSE results.

Formative Evaluation

Assessment conducted during the formative stages of learning to provide feedback and pinpoint parts of a task not mastered.

Summative Evaluation

Judgment of achievement at the end of an instructional unit or training period to indicate the final level reached by a learner.

Norm-Referenced Standards

The judgment of an individual’s performance in relation to the performance of other members of a well-defined group.

Criterion-Referenced Standards

Predetermined standards of performance used to determine if a learner has attained a specific level of proficiency regardless of other students.

Validity

The quality of a test that ensures it measures what it is intended to measure.

Content Validity

The extent to which a test adequately covers the syllabus and samples the major topics taught.

Construct Validity

A type of validity referring to the kinds of learning specified or implied in the course objectives.

Reliability

The degree to which a test produces consistent or dependable results over repeated administrations or different examiners.

Internal Consistency (Cronbach Alpha)

A measure of reliability evaluating the consistency of a whole set of items in measuring a single construct.

Taxonomy

A classification system; in education, it refers to the categories of learning behaviors (Cognitive, Affective, Psychomotor).

Cognitive Domain

The domain of learning dealing with intellectual development, categorized by Bloom into six levels from Knowledge to Evaluation.

Affective Domain

The domain of learning dealing with the development of feelings, values, and attitudes.

Psychomotor Domain

The domain of learning dealing with manual, motor, or practical skills development.

Knowledge (Bloom's Taxonomy)

The lowest level of the cognitive domain, involving the recall or reproduction of information and facts.

Synthesis (Bloom's Taxonomy)

The cognitive process of using skills to create a completely new product or idea that did not exist before.

SMART Principle

Acronym for Specific, Measurable, Achievable, Relevant, and Time-bound; the criteria for writing effective objectives.

Table of Specifications

A two-dimensional grid used in test planning that aligns subject-matter topics with the cognitive abilities to be tested.

Item Difficulty Index ($ID$)

The proportion of examinees who answered an item correctly, calculated as $ID = \frac{\text{Students with correct answers}}{\text{Total students}} \times 100$.

Item Discrimination Index

A measure of how well a test item distinguishes between knowledgeable students (high scorers) and non-masters (low scorers).

Distractor Analysis

The study of incorrect response options to ensure they are plausible and attractive to students who have not mastered the content.

Mean ($\bar{X}$)

The most common measure of central tendency calculated as $\bar{X} = \frac{\sum X}{n}$, where $\sum X$ is the sum of scores.

Standard Deviation ($S.D.$)

A measure of variability indicating how much scores deviate from the mean, often calculated using the formula $S.D. = \sqrt{\frac{\sum (X-\bar{X})^2}{n-1}}$.
