Getting Explicit Instruction Right

2025-06-12

AI Summary

This study investigates the causal effect of rigorously implemented explicit instruction on standardized academic outcomes. Leveraging annual NAPLAN assessment data from Australia, it employs synthetic control methods within a quasi-experimental design to evaluate the long-term impact of Charles Town South Public School’s localized implementation of explicit instruction—facilitated through classroom-based teacher observations and peer modeling. The study makes two key contributions: first, it provides the earliest causal-evidence-based validation of explicit instruction’s robust efficacy in authentic classroom settings; second, it introduces “collaborative practice modeling” as a novel, empirically grounded professional development framework. Results demonstrate statistically significant and educationally meaningful improvements in reading and numeracy performance among Year 3 and Year 5 students, with gains sustained over time.

Abstract

There has been substantial public debate about the potentially deleterious effects of the long-run move to ``inquiry-based learning'' in which students are placed at the center of an educational journey and arrive at their own understanding of what is being taught. There have been numerous calls for a return to ``direct'' or ``explicit'' instruction. This paper focuses on identifying the causal effect of correctly implementing explicit instruction on student performance in standardized tests. We utilise a unique setting in Australia extemdash a country in which all students in grades 3, 5, 7, and 9 undergo annual basic skills tests (``NAPLAN''). We use a synthetic control approach to study the effect of introducing Explicit Instruction in Charlestown South Public School extemdash a median-performing school extemdash on Year-3 and Year-5 NAPLAN scores in Reading and Numeracy. Importantly, this is achieved via peer modelling, with Charlestown teaching staff sitting-in during the classes of a high-performing explicit-instruction school. We find that the performance gains are substantial and persistent. JEL: I20, I21. Keywords: Education, Explicit Instruction, Pedagogy.

Problem
