On-Line Computer Terminal Performance on Science Related Tasks of Concept-Attainment.
Smith, Thomas Eugene
This study was designed to identify patterns of selections and performance characteristics displayed by individuals during a concept-attainment task. The relationships between selection patterns and individual characteristics were studied in addition to the effects of changes in task characteristics on selection patterns. The population was 200 elementary teacher education majors and 37 secondary science teacher education majors who were randomly selected. The concept-attainment tasks were presented to the learners with an on-line computer teletype terminal. The tasks were programmed simulations of the development of a chemical analysis scheme for identifying the presence of a contaminating substance. Analysis of variance of the selection patterns and the performance characteristics of the learner indicated significant differences between individuals but no significant differences within individuals across similar tasks. There was a trend to more correct identifications of the concept with a matrix presentation of feedback than with a linear presentation. Matrix presentation also tended to shift learners' patterns toward analytic style. (Author/BR)
