LET · Get comfortable with the vocabulary.

Allegory

A story, poem, or painting in which characters and events stand for larger moral, religious, or political ideas, so the surface narrative carries a second, deeper meaning from start to finish.

Related: Sonnet
Hyperbole

A deliberate exaggeration used for emphasis or humor rather than literal truth, as in "I've told you a million times," which no reader is expected to take as a fact.

Related: Allegory
Sonnet

A fourteen-line poem written in a fixed meter and rhyme pattern, usually turning from a problem or question in its opening lines to a resolution or insight at the end.

Related: Allegory, Tula
Subject-verb agreement

The grammar rule that a verb must match its subject in number and person, so a singular subject takes a singular verb and a plural subject takes a plural verb.

Main idea

The central point a paragraph or passage is built to support; every other sentence explains, illustrates, or qualifies it, and it can usually be stated in one sentence.

Related: Context clues, Reading fluency
Photosynthesis

The process by which green plants, algae, and some bacteria use sunlight, water, and carbon dioxide to make sugar, releasing oxygen as a by-product.

Related: Symbiosis, Greenhouse effect
Mitosis

The type of cell division that produces two genetically identical daughter cells, used for growth, repair, and replacement of body cells in multicellular organisms.

Symbiosis

A close, lasting relationship between organisms of different species, which may benefit both partners, benefit one while harming the other, or benefit one while leaving the other unaffected.

Related: Photosynthesis
Plate tectonics

The theory explaining that Earth's outer shell is broken into large moving slabs whose collisions, spreading, and sliding cause earthquakes, volcanoes, mountain building, and the drift of continents.

Related: Greenhouse effect
Greenhouse effect

The warming of Earth's surface that occurs when certain gases in the atmosphere trap heat radiating from the ground, keeping the planet habitable but intensifying with added emissions.

Related: Photosynthesis, Plate tectonics
Inflation

A sustained rise in the general level of prices across an economy, which reduces the amount of goods and services a given sum of money can buy.

Separation of powers

The constitutional arrangement that divides government authority among legislative, executive, and judicial branches so that no single branch can exercise unchecked control.

Quadratic equation

An equation of the form ax^2 + bx + c = 0, where a is not zero, whose solutions can be found by factoring, completing the square, or the quadratic formula.

Related: Measures of central tendency
Measures of central tendency

Summary values-mean, median, and mode-that describe the typical or middle score of a data set; each is chosen according to the data's shape and level of measurement.

Related: Quadratic equation
Constructivism

A learning theory holding that learners build new understanding by connecting new information to what they already know, so teaching should provide experiences and questions rather than only transmitted facts.

Related: Zone of proximal development, Scaffolding, Metacognition
Behaviorism

A theory that treats learning as a change in observable behavior produced by stimuli, reinforcement, and punishment, with little attention to internal mental processes.

Related: Constructivism
Zone of proximal development

The gap between what a learner can do alone and what the learner can accomplish with guidance from a more capable person; instruction is most effective when aimed at this range.

Related: Scaffolding, Constructivism
Scaffolding

Temporary support-such as prompts, models, or step-by-step guides-given to a learner during a task and gradually withdrawn as competence grows.

Related: Zone of proximal development, Differentiated instruction
Bloom's taxonomy

A hierarchical classification of learning objectives in the cognitive domain, moving from remembering and understanding through applying and analyzing to evaluating and creating.

Related: Table of specifications, Formative assessment
Formative assessment

Ongoing, low-stakes checks of student understanding during instruction, used mainly to adjust teaching and give feedback rather than to assign a final grade.

Related: Summative assessment, Rubric
Summative assessment

An evaluation given at the end of a unit, term, or course to judge how much learning has occurred, usually reported as a grade or score for accountability.

Related: Formative assessment, Table of specifications
Differentiated instruction

Planning lessons so that content, process, product, or learning environment are adjusted to fit students' readiness, interests, and learning profiles within the same classroom.

Related: Scaffolding, Inclusive education
Rubric

A scoring guide that lists the criteria for a task and describes levels of quality for each criterion, making grading more consistent and understandable to students.

Related: Formative assessment, Summative assessment
Individualized Education Program

A written plan required for a learner with a disability, specifying present levels of performance, measurable goals, services, accommodations, and how progress will be monitored.

Related: Inclusive education, Differentiated instruction
Metacognition

Awareness and regulation of one's own thinking-knowing what one understands, planning an approach, monitoring progress, and adjusting strategies when comprehension breaks down.

Related: Constructivism, Formative assessment
Table of specifications

A test blueprint that maps test items to learning objectives and content areas and sets the number or weight of items for each, helping ensure balanced content coverage.

Related: Bloom's taxonomy, Reliability
Reliability

The consistency of a test or measurement-whether it yields similar results when repeated, scored by different raters, or made up of comparable items.

Related: Table of specifications
Spiral progression

A curriculum design that revisits key concepts across grade levels with increasing depth and complexity, so earlier learning is reinforced and extended rather than abandoned.

Related: Bloom's taxonomy
Inclusive education

The practice of educating learners with disabilities and other diverse needs in regular classrooms with appropriate support, rather than segregating them in separate settings.

Related: Individualized Education Program, Differentiated instruction
Phonics

An approach to teaching reading that links letters and letter patterns to the sounds they represent, helping beginners decode unfamiliar printed words.

Related: Context clues, Reading fluency
Context clues

Hints about an unfamiliar word's meaning supplied by the surrounding sentence or passage, such as a definition, example, contrast, or cause-and-effect relationship.

Related: Reading fluency, Main idea
Reading fluency

The ability to read text accurately, at an appropriate rate, and with suitable expression, which frees attention for comprehending what is read.

Related: Phonics, Context clues
Place value

The value assigned to a digit based on its position in a numeral, so in 4,582 the 5 stands for five hundreds rather than five ones.

Related: Quadratic equation
Scientific method

A systematic procedure for investigating questions: observing, forming a testable hypothesis, experimenting or gathering data, analyzing results, and drawing conclusions that may later be revised.

Related: Primary source
Primary source

An original document, artifact, recording, or eyewitness account created during the period under study, used as direct evidence rather than as a later interpretation.

Related: Scientific method
Values clarification

A teaching approach that helps learners examine their beliefs, weigh alternatives and consequences, and freely choose and act on values rather than having them imposed.

Physical fitness

A state of health and well-being that allows a person to perform daily tasks and physical activity with vigor, built through components such as cardiorespiratory endurance, strength, flexibility, and body composition.

Tula

A Filipino term for poetry: a literary composition in verse that uses rhythm, imagery, and often rhyme to express feeling or thought, traditionally recited or chanted.
