Antecedents affecting science achievement scores in classrooms in Trinidad and Tobago

Abstract

This paper initially notes the role of scientific education in a developing country and the need to enhance scientific education among the school population. Enhancement of science education for all pupils is dependent on the distribution of schools, quality of schools and pupil participation in any country. To understand how science education is advanced in a developing country it is also important to know who is currently succeeding in science education in schools and to understand how this success is distributed amongst the school population. Thus, this paper questions whether school-based science achievement may be predetermined by antecedent factors or whether there is an equal opportunity of success amongst all pupil participants. A review of the literature has found that many antecedent factors affect school and science achievement, and these factors may be more important than within-school processes thought to enhance science education. The antecedent factors refer to: social/home background; age, religion and sex of the pupil; school class level and size; type of school attended and its locality. This study assesses how antecedent factors affect science performance in a representative sample of pupils in primary and secondary schools throughout Trinidad and Tobago. The representative sample totalled 1998 children, aged 6-10 years. Pupils were selected from a geographic transect of Trinidad and Tobago, which fulfilled demographic criteria. Once pupils were selected, biographic data were obtained for each child. Science achievement was measured by an end-of-term science examination designed for each class by the class teacher and graded on a 100% scale (within each class). Within class pupil scores were 'standardized' for comparisons between classes, schools, etc. Results from the analyses are summarized as: science achievement scores decrease as pupils increase in age. Girls perform consistently better than boys, with a slight variation in the sex by religion by school level interaction. Pupils in private schools score higher than pupils in similar levels of state schools. Pupils from a middle class background perform better than pupils from a working class background. Differences in performance relate to the religion of the child, with Muslim pupils scoring higher than Hindu or Christian pupils. Pupils in single-sex schools perform at higher levels than pupils in co-educational schools, and this is true for girls-only and boys-only schools. At the secondary school level the type of school attended is related to science achievement performance with pupils in prestige (usually church controlled) schools performing better than pupils in the comprehensive (state controlled) schools. The results support, develop and refine the previous literature on school and science achievement. Unusually, girls are at the forefront of science achievement in both primary and secondary schools. Also, traditional prejudices of social class, school status and location are confirmed within the school system in Trinidad and Tobago. A number of directions for future research and classroom action studies are indicated which focus on the existence of these inequalities. © 1988.
