K-12 intervention studies often include fidelity of implementation (FOI) as a mediating variable, though most do not report the validity of fidelity measures. This article discusses the critical need for validated FOI scales. To illustrate our point, we describe the development and validation of the Implementation Validity Checklist (IVC-R), an…

This study examined teachers' language use across the school year in 6th grade urban middle-school classrooms (n = 24) and investigated the influence of this classroom-based linguistic input on the reading comprehension skills of the students (n = 851; 599 language minority learners and 252 English-only) in the participating classrooms. Analysis…

Empirical analysis of secondary biology classrooms revealed that, on average, 68% of teaching time in Germany revolved around processing tasks.
