Explore different theoretical perspectives on development, such as modernization theory, dependency theory, and world-systems theory. Analyze the strengths and weaknesses of each approach in understanding the politics of development.
Theories of Development – Study Notes
1. Overview
- Goal of developmental theories – Explain how and why people change physically, cognitively, and socially from birth through adulthood.
- Two broad perspectives
- Stage‑based – Development proceeds through qualitatively different periods.
- Continuous/Process‑based – Change is gradual, cumulative, and shaped by ongoing interactions with the environment.
2. Psychoanalytic & Psychodynamic Theories
| Theorist |
Core Idea |
Key Stages / Concepts |
Educational Implications |
| Sigmund Freud |
Personality develops through conflicts among id, ego, superego; early experiences are decisive. |
Psychosexual stages – Oral (0‑1 yr), Anal (1‑3 yr), Phallic (3‑6 yr), Latency (6‑puberty), Genital (puberty‑adult). |
Emphasize safe, supportive early environments; recognize how unresolved conflicts may affect behavior. |
| Erik Erikson |
Lifespan extension of Freud; each stage involves a psychosocial crisis that must be resolved. |
8 stages – Trust vs. Mistrust, Autonomy vs. Shame, Initiative vs. Guilt, Industry vs. Inferiority, Identity vs. Role Confusion, Intimacy vs. Isolation, Generativity vs. Stagnation, Integrity vs. Despair. |
Classroom climate should foster competence, identity exploration, and supportive relationships at each age. |
| Anna Freud / John Bowlby (Attachment) |
Early attachment shapes later emotional regulation and relationships. |
Secure, anxious‑ambivalent, anxious‑avoidant, disorganized attachment patterns. |
Consistent caregiver presence → secure attachment → better academic engagement. |
3. Cognitive Development Theories
| Theorist |
Core Idea |
Main Stages / Processes |
Classroom Applications |
| Jean Piaget |
Children construct knowledge through active interaction; development is stage‑like. |
Sensorimotor (0‑2 yr) → Preoperational (2‑7) → Concrete Operational (7‑11) → Formal Operational (11‑adult). |
Use hands‑on activities (sensorimotor), concrete manipulatives (concrete ops), and abstract problem‑solving (formal ops). |
| Lev Vygotsky |
Social interaction and cultural tools drive cognition; learning precedes development. |
Zone of Proximal Development (ZPD) – tasks a child can perform with guidance. |
Scaffolding, collaborative learning, language‑rich environments. |
| Information‑Processing Theory |
Mind functions like a computer: encoding, storage, retrieval; development is quantitative (speed, capacity). |
Attention, working memory, long‑term memory, executive functions improve with age. |
Teach metacognitive strategies, chunking, graphic organizers. |
| Robert Siegler (Overlapping Waves) |
Multiple strategies coexist; children gradually favor more efficient ones. |
Emphasizes variability and gradual shift rather than abrupt stage change. |
Encourage strategy discussion; allow multiple solution paths. |
4. Moral Development
| Theorist |
Core Idea |
Stages |
Educational Relevance |
| Lawrence Kohlberg |
Moral reasoning evolves through hierarchical stages. |
