Mining Data from Documents
Interviewing and observing are two data collection strategies designed to gather data that specifically address the research question. Documents, however, are usually produced for reasons oilier than the research at hand and therefore are not subject to the same limitations. The presence of documents does not intrude upon or alter the setting in ways that the presence of the investigator often does. Nor are documents dependent upon the whims of human beings whose cooperation is essential for collecting good data through interviews and observations.

Sternberg believes that intellectual skills and thinking skills are inseparable, there is more to intelligence than thinking. With this as background, Stemberg developed a triarchic theory of Intelligence, consisting of three elements designed to explain each of his three ideas of what intelligence "should do" He labeled the three elements componential, experiential, and contextual.

 

Two definitions of critical thinking will be offered here as a reference for our work. The first is offered by Robert Ennis and is rootle in philosophy. "Critical thinking is reasonable reflective thinking that is focused on deciding what to believe or do". Ennis believes that terms are key to this definition: practical, reflective, reasonable, belief, and action. Critical thinking is an activity, both practical and reflective, that has reasonable belief or action as its goal. When we come to investigate the skills that emerge from this definition, well discover chat Ennis's definition includes dispositions as well as abilities.
