Differential Effectiveness of Alternative Middle School Science Sequences for Students of Different Ethnicities

• In Event: Investigating K–12 Learning Environments

Abstract

For a sample of 367 middle-school students in the USA, we employed learning environment criteria to evaluate two alternative science curriculum sequences (generalized/integrated curriculum and topic-specific curriculum) and to investigate the differential effectiveness of the alternative sequences for two different ethnic groups (Caucasian and Hispanic). The six reliable learning environment scales used were Personal Relevance, Student Cohesiveness, Teacher Support, Investigation/Involvement, Task Orientation, and Enjoyment of Science). Science was enjoyed more by both Caucasian and Hispanic students experiencing the topic-specific sequence (effect size of 0.74 standard deviations). In terms of task orientation, Hispanic students benefitted more from the general curriculum model, but the two curriculum sequences were equally effective for Caucasian students.
