Subject competency of teachers and level of dependence on resource packs to teach levers, gears and pulleys

Abstract

This pilot study set out to ascertain whether the level of dependence on resource material is related to teaching experience, existing understanding in mechanics, and perceived self confidence in science and technology. Details of teaching experience and qualifications were obtained from 11 experienced teachers and 10 initial teacher trainees, and understanding of mechanics was assessed by a written test. Each teacher worked through one commercially produced inservice pack about levers, pulleys or gears, and then prepared a 30 minute session for 4 ten year old children. Videos of the sessions were analysed with respect to the extent to which the pack was the sole focus; the amount of integration with other teaching aids and approaches; and the extent individual children's needs were satisfied. Although science qualifications influenced teacher confidence, they were not accurate predictors of relevant knowledge and teaching competence. As the majority of teachers followed pack instructions closely, the children's needs were not always well matched.
