Abstract Reasoning Comparative Analysis Data Interpretation Error Analysis (Language) Error Patterns High School Students Online Searching Scores Search Strategies Secondary Education Self Esteem Sex A study of 191 juniors and seniors from 6 Oahu high schools tested their ability to interpret and construct search statements after reading brief instructions on concept analysis, Boolean operators, and search statement format. On average, students made two errors per statement; scores and types of errors are examined for influences of gender and self-confidence. (PEN)
