Educational Psychology: Development, Learning and the Learner
Piaget: Four Stages, and the Symptom That Names Each
Piaget said children are not small adults with less knowledge — they think differently in kind, and the kind changes in a fixed order. Two words carry his whole system. Assimilation is fitting a new thing into a scheme you already have: a child who knows "dog" calls a goat a dog. Accommodation is changing the scheme because the new thing will not fit: the child learns that goats are a separate kind. Learning, for Piaget, is the back-and-forth between the two, and the engine is the child's own activity — which is why his name attaches to activity-based teaching rather than to explanation.
| Stage | Age | What the child does |
|---|---|---|
| Sensorimotor | 0–2 years | Knows the world by acting on it. Gains object permanence — the hidden toy still exists. |
| Pre-operational | 2–7 years | Symbols and pretend play arrive; egocentrism and failure to conserve remain. The taller glass "has more". |
| Concrete operational | 7–11 or 12 years | Logic works — on things present. Conservation, seriation, classification, reversibility all arrive. Abstraction does not. |
| Formal operational | 11–12 years onward | Reasons about the possible, not only the actual — hypotheses, algebra, "what if". |
Vygotsky and Kohlberg: The Social Child and the Moral Child
Where Piaget has the child discovering alone, Vygotsky has the child learning through other people first and alone afterwards. His two examinable terms: the Zone of Proximal Development (ZPD) is the gap between what a learner can do unaided and what the same learner can do with help; scaffolding is the help — a hint, a worked first step, a question at the right moment — which is deliberately withdrawn as the learner takes over. Add private speech: a child muttering through a sum is not misbehaving, she is using language as a tool of thought, and Vygotsky expects it.
- ZPD is not "difficult work". It is work just beyond independent reach. Below it the child is bored; above it scaffolding cannot help. This is the whole argument for group work with mixed ability.
- Kohlberg, pre-conventional (roughly up to 9): right is what avoids punishment or wins reward. The child who is honest only when watched is here.
- Conventional (adolescence): right is what keeps approval and obeys the rule because it is the rule — "good boy" morality, then law and order.
- Post-conventional: right is judged against principle, and a law may be called unjust. Reached late, and by no means by everyone — an option claiming every adult reaches it is wrong.
Intelligence, Creativity and Motivation
Intelligence in this syllabus is three names and one formula. Spearman split it into a general factor g and specific factors s. Thorndike made it multi-factor. Gardner made it eight relatively independent intelligences — linguistic, logical-mathematical, spatial, musical, bodily-kinaesthetic, interpersonal, intrapersonal, naturalistic — which is the theory TET cites when it argues that a child weak in arithmetic is not a weak child. The formula is IQ = (mental age ÷ chronological age) × 100; a ten-year-old with a mental age of twelve has an IQ of 120.
Creativity is divergent thinking — many answers to one question — against the convergent thinking that hunts a single right one. Its four examinable marks are fluency (how many ideas), flexibility (how many kinds of idea), originality (how rare) and elaboration (how far developed). Nothing kills it faster than a task with one acceptable output, which is why "give detailed instructions so every result is uniform" is always the wrong option in a creativity question. And motivation divides in two: intrinsic, where the activity is its own reward, and extrinsic, where a star or a mark is. TET consistently treats intrinsic as the sounder aim, because extrinsic motivation stops working the moment the reward stops.
Key takeaways
- Growth is quantitative and stops; development is qualitative and is lifelong. Both are always heredity and environment — never one alone.
- Piaget by symptom: object permanence is sensorimotor, failure to conserve is pre-operational, conservation and classification are concrete operational, hypothetical reasoning is formal operational.
- Vygotsky's ZPD is the gap between unaided and assisted performance, and scaffolding is help designed to be withdrawn. Kohlberg runs pre-conventional (punishment and reward) to conventional (approval and law) to post-conventional (principle).
- IQ = (mental age ÷ chronological age) × 100. Creativity is divergent thinking measured as fluency, flexibility, originality and elaboration. Intrinsic motivation outlasts extrinsic because it does not depend on the reward continuing.
Practice questions (8)
Attempt each one before opening the answer. Every explanation names the tempting wrong option as well as the right one, because that is where marks are lost.
Which statement states the difference between growth and development correctly?
Show answer
Answer: C — Growth refers to quantitative change and largely stops; development refers to qualitative change and is lifelong.
Growth is the measurable part — height, weight, number of teeth — and it slows and stops broadly by the end of adolescence. Development is change in kind: from babbling to argument, from grasping to writing, and it continues through life. The most tempting wrong option simply swaps the two and says growth is lifelong; that reversal is the single most common error on this question. The option splitting heredity and environment between them is wrong by construction, since both growth and development are produced by the two together. And development is not unobservable — improved motor skill and social behaviour are exactly how it is observed.A child is shown two identical glasses of water. The water from one is poured into a taller, narrower glass, and the child insists the taller glass now has more water. In which of Piaget’s stages is this child?
Show answer
Answer: B — Pre-operational stage
The child is failing conservation of quantity — judging amount by height alone and not recognising that pouring changes neither the quantity nor anything reversible about it. Failure to conserve is the defining limitation of the pre-operational stage, roughly two to seven years. The concrete operational option is the trap, and it catches candidates who match the word "conservation" to the stage where conservation is present: a child who SUCCEEDS at this task is concrete operational, and this child fails it. Sensorimotor is the infant stage whose landmark is object permanence, and formal operational reasoning deals with hypotheses and abstractions well beyond this task.A child who knows the word “dog” points at a goat and calls it a dog. Later she learns that goats are a different animal and forms a separate category for them. In Piaget’s terms, the two events are respectively:
Show answer
Answer: C — Assimilation, then accommodation
Assimilation is fitting something new into a scheme that already exists, which is exactly what calling a goat a dog does — the goat is forced into the "dog" category. Accommodation is altering the scheme because the new thing will not fit, which is what forming a separate category for goats does. The reversed option is the trap and it is chosen by candidates who remember the pair of words but not their order; the test is whether the scheme stayed the same, which is assimilation, or changed, which is accommodation. Conservation and reversibility are concrete-operational achievements about quantity, not about how a category absorbs a new instance, and egocentrism concerns the inability to take another viewpoint.A pupil can solve five-digit subtraction with the teacher prompting the borrowing step, but not yet on her own. Vygotsky would say the task lies in her:
Show answer
Answer: D — Zone of proximal development
The zone of proximal development is precisely the band between what a learner can already do unaided and what the same learner can do with competent help. A task she completes only with a prompt sits inside that band, and the prompt itself is scaffolding — help designed to be withdrawn as she takes the step over. The most tempting wrong option is the level of actual independent performance, but that names what she can do WITHOUT help, which by the stem is not this task. The two Piagetian options belong to a different theorist and a different question: they describe what kind of thinking a child is capable of, not the difference between assisted and unassisted work.A boy of eight returns a dropped wallet only because a teacher is standing nearby and he expects to be praised. On Kohlberg’s scheme his reasoning is at the:
Show answer
Answer: A — Pre-conventional level
At the pre-conventional level, roughly up to nine years, right and wrong are decided by the consequence to oneself: avoid punishment, obtain reward. Acting well only while an authority is watching, and for the praise, is that reasoning exactly. The conventional option is the trap, and the distinction is worth holding: a conventional child returns the wallet because honesty is what a good boy does or because the rule says so, whether or not anybody is watching. The post-conventional and autonomous principled options describe judging an act against a principle that may even override a law, which is reached late and by no means by everyone.A child aged 10 years is assessed to have a mental age of 12 years. What is the child’s intelligence quotient?
Show answer
Answer: C — 120
The intelligence quotient is mental age divided by chronological age, multiplied by 100. Here that is (12 ÷ 10) × 100 = 120. The value 83 is what the same arithmetic gives if the two ages are put the wrong way round, (10 ÷ 12) × 100, and it is the option that catches most candidates. A quotient of 100 would mean mental age and chronological age are equal, which the stem contradicts, and 122 comes from adding the two-year difference to 120 rather than from the formula at all.Which strategy is most likely to foster creativity in a primary classroom?
Show answer
Answer: B — Setting open-ended tasks that admit several solutions and several forms of expression
Creativity is divergent thinking, measured as fluency, flexibility, originality and elaboration, and all four need room for more than one acceptable output. Open-ended tasks give exactly that room. Detailed instructions aimed at uniform results are the most tempting wrong answer because they look like good teaching, but uniformity of outcome is the precise opposite of what divergent thinking produces. Restricting the class to convergent tasks defines away the thing being fostered, since convergence hunts a single right answer. Memorising facts first is not useless, but it develops recall rather than the generation of ideas.A teacher notes that a pupil from a household with few books reads poorly but reasons well in oral discussion, and considers that both the home environment and the child’s own aptitude are at work. This position corresponds to:
Show answer
Answer: D — The interaction of heredity and environment
The teacher is holding two causes together — an environmental one, the bookless home, and an inherited one, the child’s own aptitude — which is exactly the nature-and-nurture interaction that this syllabus insists on: heredity sets a range and environment decides where within it the child lands. Multiple intelligences is the strongest distractor, and it is genuinely relevant to a child who reasons orally but reads poorly, since it would treat those as separate intelligences; but it is a theory about the STRUCTURE of ability, not about what causes ability to develop, which is what the stem describes. Readiness concerns whether a child has matured enough for a particular skill, and the zone of proximal development concerns the gap between assisted and unassisted performance — neither is a claim about heredity and environment.
