Development of an instrument for assessing the psychosocial environment of science laboratory classes

Abstract

This paper attempts to stimulate and facilitate future research and practical applications involving the psychosocial environment of science laboratory classrooms by describing the development of a new instrument, the Science Laboratory Environment Inventory (SLEI), which assesses eight dimensions of the actual and preferred environment of science laboratory classes at the upper secondary school and higher education levels. Comprehensive validation information reported here in tentatively attests to the internal consistency reliability and discriminant validity of the actual and preferred forms of the SLEI for use in Australian or American classrooms. As well, further analyses supported the ability of the actual form of the SLEI to differentiate between the perceptions of students in different classrooms. It is hoped that science teachers and other researchers will make use of the SLEI to pursue several research and practical applications analogous to those completed successfully in prior work in non-laboratory classrooms.
