a person browsing the Web for entertainment will probably be less likely to evaluate displayed information than a consumer searching for car-buying information.

Evaluation is defined as the making of judgments about the value, for some purpose, of ideas, works, solutions, methods, material, etc. It involves the use of criteria as well as standards for appraising the extent to which particulars are accurate, effective, economical, or satisfying

two major strands of research usually labeled “metacognition.” One concerns knowledge about thinking, whereas the other concerns regulation of thinking and learning

that some people by nature are more likely to evaluate; that people criticize most ideas as a matter of course; and, conversely, that people must be selective about the ideas they choose to criticize. It seems most likely that the strength of critical disposition varies among individuals, but also that it varies within the same individual from situation to situation.

Signals are the specific thoughts that launch the evaluation process, a recognition that something may be wrong with the information

Influences to Evaluation

four sections suggest factors that may contribute to an understanding of gullibility and simultaneously demonstrate some common problems with the evaluation process.

The Development Continuum

he ability to evaluate increases with age

Education

school-aged children do not find inconsistencies well if they are not primed to seek them

Flavell postulates that a major difference between children and mature thinkers involves goals

. The research discussed in this section supports the conclusion that children are more vulnerable to evaluation problems than adults. Reasons for this vulnerability almost certainly include lack of education and prior knowledge and a natural tendency to believe what they see and what they are told by authority figures.

The Epistemology Continuum

Epistemology is a branch of philosophy dealing with the nature of knowledge and the sources of knowledge

the beliefs that people hold about how we come to know what we know.

A person who is feeling happy will be more likely than at other times to reduce the load on working memory: to reduce the complexity of decision situations and the difficulty of tasks, by adopting the simplest strategy possible, considering the fewest number of alternatives possible, and doing little or no checking of information, hypotheses, and tentative conclus

Students should be brought to the understanding that while it is impossible to have domain knowledge about all topics, it is important to build knowledge in selected areas to help with important decisions and projects.

Research projects should culminate in the production of different types of media.

There is no better way to practice evaluation than to perform research regularly and intensely.

When a skill is introduced, or when students seem to be having inordinate difficulty, teachers and school library media specialists can reduce cognitive load by breaking the skill down into smaller parts (Markman 1981), and by beginning new skills in familiar contexts (Flavell 1981). For example, in distinguishing between fact and opinion, students can first seek cue words like “I think . . .” and “I feel .

on evaluation is important to the individual, to the educational establishment, and to society. For individuals, evaluation is a crucial life skill and a basis for lifelong learning. It is required in decision making and imparts a feeling of self-esteem through control. Evaluation is important to the educational establishment, because critical thinking is arguably one of the most important of all educational outcomes for students (Engeldinger 1991). Finally, society must critically evaluate information to establish a public demand for high information quality.

Evaluation consists of a number of component processes, including metacognition, goals, personal disposition, signals (which initialize an evaluative episode), deliberation, and decision. Research sho
