Professional learning communities among vocational school teachers: Profiles and relations with instructional quality

Although improving teachers' classroom strategies presents the primary goal of PLCs, empirical evidence is still scarce, mainly derived from case-study material and confined to (pre-) K12 settings. We use profiling techniques and a comparative design to examine (a) distinct configurations in which PLCs occur within vocational school departments, and (b) their relations to instructional quality. Multilevel latent profile analysis, based on teacher assessments of core PLC dimensions, reveals three configurations. Multilevel multiple group analysis of students' instructional ratings shows that teachers from Advanced PLC departments create more authentic, application-oriented learning environments than teachers from other departments.
