The authors (Collins, Brown, & Holum, 1991; Collins, Brown, & Newman,1989) as well as other researchers (Herrington & Oliver, 2000) have refined this model to the belief that useable knowledge is best gained in learning environments featuring the following characteristics:   Authentic context that allows for the natural complexity of the real world Authentic activities Access to expert performances and the modeling of processes Multiple roles and perspectives Collaboration to support the cooperative construction of knowledge Coaching and scaffolding which provides the skills, strategies and links that the students are initially unable to provide to complete the task Reflection to enable abstractions to be formed Articulation to enable tacit knowledge to be made explicit

The goal of learning, therefore, is to engage learners in legitimate peripheral participation in communities of practice (Lave and Wenger 1991). Through community, learners interpret, reflect, and form meaning. Community provides the setting for the social interaction needed to engage in dialogue with others to see various and diverse perspectives on any issue. Community is the joining of practice with analysis and reflection to share the tacit understandings and to create shared knowledge from the experiences among participants in a learning opportunity (Wenger 1998).

The goal of cognitive apprenticeship is to address the problem of inert knowledge and to make the thinking processes of a learning activity visible to both the students and the teacher.  T

The term ‘scaffolding’ comes from the works of Wood, Bruner and Ross (1976). The term ‘scaffolding’ was developed as a metaphor to describe the type of assistance offered by a teacher or peer to support learning. In the process of scaffolding, the teacher helps the student master a task or concept that the student is initially unable to grasp independently. The teacher offers assistance with only those skills that are beyond the student’s capability. Of great importance is allowing the student to complete as much of the task as possible, unassisted. The teacher only attempts to help the student with tasks that are just beyond his current capability. Student errors are expected, but, with teacher feedback and prompting, the student is able to achieve the task or goal. When the student takes responsibility for or masters the task, the teacher begins the process of “fading”, or the gradual removal of the scaffolding, which allows the student to work independently. “Scaffolding is actually a bridge used to build upon what students already know to arrive at something they do not know. If scaffolding is properly administered, it will act as an enabler, not as a disabler” (Benson, 1997).

Metacognitive experiences involve the use of metacognitive strategies or metacognitive regulation (Brown, 1987). Metacognitive strategies are sequential processes that one uses to control cognitive activities, and to ensure that a cognitive goal (e.g., understanding a text) has been met. 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.

Self-questioning is a common metacognitive comprehension monitoring strategy. If she finds that she cannot answer her own questions, or that she does not understand the material discussed, she must then determine what needs to be done to ensure that she meets the cognitive goal of understanding the text.

Knowledge is considered to be metacognitive if it is actively used in a strategic manner to ensure that a goal is met. For example, a student may use knowledge in planning how to approach a math exam: "I know that I (person variable) have difficulty with word problems (task variable), so I will answer the computational problems first and save the word problems for last (strategy variable)." Simply possessing knowledge about one's cognitive strengths or weaknesses and the nature of the task without actively utilizing this information to oversee learning is not metacognitive.

a situation where an object’s sensory characteristics intuitively imply its functionality and use.

An affordance is a desirable property of a user interface – software which naturally leads people to take the correct steps to accomplish their goals.

An affordance is a quality of an object, or an environment, that allows an individual to perform an action.

Feeding students endless content to remember (that is, declarative sentences to remember) is akin to repeatedly stepping on the brakes in a vehicle that is, unfortunately, already at rest. Instead, students need questions to turn on their intellectual engines and they need to generate questions from our questions to get their thinking to go somewhere. Thinking is of no use unless it goes somewhere, and again, the questions we ask determine where our thinking goes.

It is possible to give students an examination on any subject by just asking them to list all of the questions that they have about a subject, including all questions generated by their first list of questions.
