Associations Between Student Outcomes and Psychosocial Science Environment

Abstract Past research on classroom environment was extended to science laboratory class settings in an investigation of associations between student outcomes and classroom environment. The sample consisted of 1,594 senior high school chemistry students in 92 classes. The Science Laboratory Environment Inventory was used to assess student cohesiveness, open-endedness, integration, rule clarity, and material environments in the laboratory class, and student outcomes encompassed two inquiry skill and four attitude measures. Simple, multiple, and canonical analyses were conducted separately for two units of analysis (student scores and class means) and separately with and without control for general ability. Past research was replicated in that the nature of the science laboratory classroom environment accounted for appreciable proportions of the variance in both cognitive and affective outcomes beyond that attributable to general ability.

Science Laboratory Classroom Climate in British Schools and Universities

Abstract Because existing classroom environment instruments are unsuitable for science laboratory classes, we developed and validated a new instrument specifically suited to laboratory classrooms at either the upper secondary school or higher education level. The Science Laboratory Environment Inventory assesses students’ or teachers’ perceptions of five dimensions of actual or preferred classroom environment, namely, student cohesiveness, open‐endedness, integration, rule clarity, and material environment. A distinctive feature of the study was that the instrument was field tested cross‐nationally and validated in six different countries, namely, England, Canada, Australia, USA, Israel, and Nigeria. The total sample consisted of 5447 students in 269 individual science laboratory classes. Various analyses attested to each scale's internal consistency reliability, discriminant validity, factorial validity, predictive validity, and ability to differentiate between the perceptions of students in different cl...

Assessment of the psychosocial environment of university science laboratory classrooms: a cross-national study

A strong tradition in educational research has involved several widely-used instruments assessing student or teacher perceptions of characteristics of actual or preferred classroom psychosocial environment. Existing instruments, however, are unsuitable for one of the most important settings in science teaching, namely, the science laboratory class. Consequently, the present research aimed to develop and validate a new instrument, the Science Laboratory Environment Inventory (SLEI), which is specifically suited to science laboratory environments at the higher education level. The SLEI assesses students' or teachers' perceptions of five dimensions of actual or preferred classroom environment, namely, Student Cohesiveness, Open-Endedness, Integration, Rule Clarity, and Material Environment. A distinctive feature of the design of the study was that the instrument was field tested and validated cross-nationally in six different countries, namely, the USA, Canada, Australia, England, Israel, and Nigeria. The total sample consisted of 1720 students in 71 university laboratory classes. Various item and factor analyses guided the evolution of a refined version, and attested to each SLEI scale's internal consistency reliability, discriminant validity, factorial validity, predictive validity (i.e., ability to predict student outcomes), and ability to differentiate between the perceptions of students in different classes. An important finding was that the SLEI is equally valid for use in its actual and preferred versions, and for the individual or the class mean as the unit of analysis. As well, separate within-country analyses confirmed the validity and usefulness of the SLEI in each of the six countries involved in the field testing. Overall, the study attested to the general advantages of employing cross-national designs in learning environment research.

Research into the environment of science laboratory classes in australian schools

Existing instruments for assessing student or teacher perceptions of characteristics of actual or preferred classroom psychosocial environment are unsuitable for one of the most important settings in science teaching, namely, the science laboratory class. Consequently, the Science Laboratory Environment Inventory (SLEI), was designed to assess student or teacher perceptions of seven scales:Teacher Supportiveness, Student Cohesiveness, Open-Endedness, Integration, Organization, Rule Clarity andMaterial Environment. An important feature of the design of the study was that the new instrument was field tested simultaneously in six countries: Australia, USA, Canada, England, Nigeria and Israel. This paper is based on a sample of 4643 students in 225 individual laboratory classes, together with the teachers of most of these classes. Preliminary analyses were used to shed light on various important research questions including the differences between Actual and Preferred environments, gender differences in perceptions of Actual and Preferred environment, the relationship between the science laboratory environment and attitude towards science laboratory work, differences between school and university laboratory classes, differences between teachers’ and students’ perceptions of the same laboratory classes, and differences between laboratory classes in different science subjects (Physics, Chemistry, Biology).

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

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.
