Higher level thinking
Benjamin Bloom identified six levels of cognitive demand arranged hierarchically from simple to complex: knowledge, comprehension, application, analysis, synthesis, and evaluation. Bloom's taxonomy was later revised to place synthesis (creation) as the highest level of demand above evaluation (judgment). Instruction for advanced/gifted and talented students should emphasize analysis, evaluation, and synthesis.

• Synthesis
  Students originate, integrate, and combine ideas in ways that are new to them. Students generate ideas, create plans, and produce products. Question stems include combine, integrate, modify, rearrange, substitute, plan, create, design, invent, compose, formulate, prepare, generalize, recreate.
