Information Search Process
Six stage of information search process by Kuhlthau 1991.
Describes the series of thoughts, feelings, behaviours & actions in the process of extensive research assignment .
The model reveals a search process in which a person is seeking meaning in the course of seeking information.
This is the first stage, it is the thinking stage, brainstorming, discussion basically consist of expressions such as anxiety, uncertainty, apprehension
Second stage, the individual begins to decide on the topic, understand the question, determine the keywords, the main key terms and at this stage the uncertainty is replaced by optimism as he discovers a direction
Third stage, as topics are determined, information on the topic will be gattered at this stage, divide work into smaller variables, understand the topic, gather a lot of information and at this stage the feeling of anxiety may return as information gathered may start to contradict each other. And other irrelevant information may suffice
Information evaluation starts, the user is now focused as he determines which information is relevant and which one will be discarded. He begins to develop confidence. His work begins to take a form
Fifth stage he is now sure of what is expected of him and begins to put in into complete order. He is clearly focused now and begins to enjoy himself, confidence increases and self assurances.
Work is completed at this stage, report is given, references made and a feeling of satisfaction or disappointment depending on his results
Information overload on the internet, information explosion. A search produces numerous results and sometimes irrelevant to ones needs. Skills to determine relevant data were discussed last lecture. Information search strategy is a step-by- step procedure that guides the searcher through the process of navigation on the internet
