Profiles of instructional quality in primary and secondary education: Patterns, predictors, and relations to student achievement and motivation in science

Abstract

Teachers implement different types of instruction, and the quality of their instruction is crucial for enhancing student outcomes. However, studies examining various patterns of teachers’ instructional quality are scarce, particularly in science teaching. Even fewer studies have investigated the nature of instructional quality in primary and secondary education. This study analysed the Norwegian data from the Trends in Mathematics and Science Study (TIMSS) 2015, using Grades 5 and 9 from primary and secondary education. Using multi-level latent class analysis, we identified distinct profiles of instructional quality that focused on four aspects of instructional clarity: clarity of instruction and teacher support (i.e., engaging teaching, social and emotional support, and subject domain support) at the student and classroom levels. The findings showed that the patterns of these profiles varied across different aspects of instructional quality in both grades. Further analyses revealed that student characteristics, particularly language at home and socioeconomic status, predicted the profile memberships at the student level, whereas teacher competence (i.e., self-efficacy in science teaching) predicted the profile memberships at the classroom level. In addition, different profiles of instructional quality were significantly related to motivation and, to a certain extent, achievement in science. We discuss the implications of these findings for research on instructional quality and for the design of personalized professional development programmes that aim to improve teacher instruction in primary and secondary science classrooms.
