Skills are actions students should be able to perform or demonstrate as the result of a lesson, or a unit of study. Some categories (with examples in each) are
basic skills (reading, writing, computing),
thinking skills (synthesizing, summarizing, creating, defending a point of view, examinig evidence),
production skills (planning, goal setting, evaluating progress, asking important questions),
skills of a discipline, (map reading, recognizing music tones, interpreting metaphorical language),
and social skills (listening, empathizing, considering multiple perspectives, taking turns).
When identifying the skills students should master in any unit, lesson, or lessons, teachers should be aware of both the categories of skills and the specific skills. Teaching those skills explicitly is at least as important as teaching information explicitly (Tomlinson & Strickland, p. 356).
