Child Development and Pedagogy: Stage Theories, Individual Difference and Assessment
Child Development and Pedagogy carries 30 marks in Bihar STET Paper 2 and is compulsory for every candidate, whatever the subject group. Items are situational rather than definitional: a classroom episode is described and you must name the concept that explains it.
Stage theories to keep apart
- Piaget: sensorimotor (0–2, object permanence); preoperational (2–7, egocentrism, no conservation); concrete operational (7–11, conservation and classification with real objects); formal operational (11+, hypothetical reasoning).
- Vygotsky: the ZPD is the gap between independent and guided performance; scaffolding is temporary and withdrawn as competence grows; egocentric speech becomes inner speech.
- Kohlberg: pre-conventional (punishment-obedience, exchange), conventional (good boy, law and order), post-conventional (social contract, universal principle).
- Erikson: industry vs inferiority is the 6–12 crisis, the one that matters for Classes VI–VIII.
Difference, motivation, assessment
Gardner's eight intelligences and Guilford's divergent thinking are frequently tested. Separate the slow learner (even delay, benefits from small steps and repetition) from a specific learning disability (an isolated deficit in reading, writing or mathematics in an otherwise average child). Formative assessment happens during teaching and feeds back into it; summative certifies achievement; diagnostic assessment locates the error. RTE 2009 prohibits board examinations and detention until elementary education is completed.
Worked example
A nine-year-old accepts that a reshaped clay ball keeps its mass, but cannot solve 'A > B and B > C, so A > C' unless given counters. Which stage? Conservation rules out the preoperational stage; failure on verbal transitive inference shows reasoning still anchored to concrete objects. Answer: concrete operational (7–11), not formal operational.
Traps
Egocentrism is not selfishness; the ZPD belongs to Vygotsky, not Piaget; Kohlberg's stages are not tied to fixed ages; negative reinforcement strengthens behaviour and is not punishment.
