  • Metacognition refers to higher order thinking which involves active control over the cognitive processes engaged in learning. Activities such as planning how to approach a given learning task, monitoring comprehension, and evaluating progress toward the completion of a task are metacognitive in nature.
  • "Metacognition" is often simply defined as "thinking about thinking."
  • While there are some distinctions between definitions (see Van Zile-Tamsen, 1994, 1996 for a full discussion), all emphasize the role of executive processes in the overseeing and regulation of cognitive processes.

  • Most definitions of metacognition include both knowledge and strategy components
  • According to Flavell (1979, 1987), metacognition consists of both metacognitive knowledge and metacognitive experiences or regulation. Metacognitive knowledge refers to acquired knowledge about cognitive processes, knowledge that can be used to control cognitive processes. Flavell further divides metacognitive knowledge into three categories: knowledge of person variables, task variables and strategy variables.
  • These processes help to regulate and oversee learning, and consist of planning and monitoring cognitive activities, as well as checking the outcomes of those activities.
  • What is the difference between a cognitive and a metacognitive strategy?
  • Cognitive strategies are used to help an individual achieve a particular goal (e.g., understanding a text) while metacognitive strategies are used to ensure that the goal has been reached (e.g., quizzing oneself to evaluate one's understanding of that text).
  • Metacognitive and cognitive strategies may overlap in that the same strategy, such as questioning, could be regarded as either a cognitive or a metacognitive strategy depending on what the purpose for using that strategy may be.
  • Metacognition, or the ability to control one's cognitive processes (self-regulation) has been linked to intelligence
  • Knowledge is considered to be metacognitive if it is actively used in a strategic manner to ensure that a goal is met.
  • Sternberg refers to these executive processes as "metacomponents" in his triarchic theory of intelligence (Sternberg, 1984, 1986a, 1986b). Metacomponents are executive processes that control other cognitive components as well as receive feedback from these components. According to Sternberg, metacomponents are responsible for "figuring out how to do a particular task or set of tasks, and then making sure that the task or set of tasks are done correctly" (Sternberg, 1986b, p. 24). These executive processes involve planning, evaluating and monitoring problem-solving activities. Sternberg maintains that the ability to appropriately allocate cognitive resources, such as deciding how and when a given task should be accomplished, is central to intelligence.
  • Cognitive Strategy Instruction
  • Cognitive Strategy Instruction
  • Those with greater metacognitive abilities tend to be more successful in their cognitive endeavors.
  • CSI) is an instructional approach which emphasizes the development of thinking skills and processes as a means to enhance learning. The objective of CSI is to enable all students to become more strategic, self-reliant, flexible, and productive in their learning endeavors (Scheid, 1993)
  • Metacognition enables students to benefit from instruction (Carr, Kurtz, Schneider, Turner & Borkowski, 1989; Van Zile-Tamsen, 1996) and influences the use and maintenance of cognitive strategies

    Sternberg defined intelligence as mental activity central to one's life in real-world environments; individuals "succeed" in life when they use mental skills to adapt to, select, and shape external environments. Correspondingly, in the late 1990s, Sternberg changed the name of the theory to the Theory of Successful Intelligence. As per its original name, the theory comprises three types of intelligence: analytical (also referred to as componential); practical (also referred to as contextual) and creative (also referred to as experiential).
