Sternberg's Triarchic Theory
Robert Sternberg argued that intelligence has three parts, and that real-world success needs all three working together — he called the balanced whole 'successful intelligence'. The first is analytical intelligence: the ability to analyse, evaluate, compare and judge — the kind of reasoning that traditional IQ and school exams measure best (solving a logic problem, comparing two arguments). The second is creative intelligence: the ability to deal with novelty, invent, imagine and produce original ideas or solutions to new problems (designing something that has never existed, thinking of a fresh approach). The third is practical intelligence: 'street smarts' — the ability to apply knowledge to everyday, real-world situations and to adapt to, shape or select one's environment (knowing how to handle people, manage a problem at home, get a job done). Sternberg's point for teachers is that a child who looks weak on the analytical tasks a school prizes may be strong in creative or practical intelligence, which conventional tests miss entirely. The memory hook CTET rewards: Sternberg = three intelligences — Analytical (analyse), Creative (create/novelty), Practical (apply/street smarts) — combined into successful intelligence.
