More Than Content: The Persistent Cross-Subject Effects of English Language Arts Teachers’ Instruction

Abstract

Evidence that teachers’ short-term instructional effects persist over time and predict substantial long-run impacts on students’ lives provides much of the impetus for a wide range of educational reforms focused on identifying and responding to differences in teachers’ value-added to student learning. However, relatively little research has examined how the particular types of knowledge or skills that teachers impart to students contribute to their longer-term success. In this article, we investigate the persistence of teachers’ value-added effects on student learning over multiple school years and across subject areas. We find that, in comparison with math teachers, English language arts (ELA) teachers’ impacts on same-subject standardized achievement scores are smaller in the year of instruction, but that teacher-induced gains to ELA achievement appear to reflect more broadly applicable skills that persist in supporting student learning in the long run across disciplines. Our results highlight important variation in the quality of teacher-induced learning for long-run success, distinct from the variation across teachers in more typically measured short-term learning effects.
