Understanding Growth and Development

About this chapter

This chapter builds the conceptual foundation every CTET Paper I aspirant needs before any other CDP topic. It distinguishes growth (quantitative change in size, height, weight, internal organs) from development (qualitative, progressive, orderly and coherent changes that bring functional maturity). It lays out nine principles of human development — continuity, individual differences, sequentiality (with cephalocaudal and proximodistal tendencies), generality to specificity, interrelation, interaction, differentiation in rate, integration and predictability. It then walks through the six chronological stages (prenatal, infancy and toddlerhood, early childhood, later childhood, adolescence, adulthood) with characteristic features at each. Four classic developmental issues are introduced — nature vs nurture, continuity vs discontinuity, activity vs passivity and universality vs context specificity. The chapter closes with Havighurst's developmental tasks of adolescence and the school's role in shaping cognitive, socio-emotional and behavioural development. CTET tests this directly: definition recall, identifying the principle behind a classroom incident, matching stage to characteristic, and the four debates. The 4 tests move from definition recall (Practice), to concept application (Quiz), to PYQ-grade statement and assertion items (Hard), to a 30-item mixed Mastery test.
