Title

Composing Boolean search statements : self-confidence, concept analysis, search logic and errors

Source

School library media quarterly. 24(1996) no.4, S.199-207

Year

1996

Abstract

Describes an experiment in which secondary students from 6 schools on the island of Oahu, Hawaii, were tested for their ability to interpret and construct search statements in a presearch activity. Students read brief instructions on concept analysis, Boolean operators, and search statement format. One group used a worksheet. A 10item quiz tested students' knowledge of term selection and search logic and obtained self confidence ratings after answering each question. Search statements were analyzed according to a typology of search statement errors. On average, each student made 2 errors per search statement. Students with higher self confidence ratings had significantly higher scores on all measures
