How does practice-based teacher preparation influence novices' first-year instruction?

Abstract

Background/Context: Teacher preparation suffers from a lack of evidence that guides the design of learning experiences to produce well-prepared beginners. An increasing number of teacher educators are experimenting with practice-embedded approaches to prepare novices for ambitious instruction. This study examines the role of core instructional practices introduced during preparatory experiences in shaping novices' first-year teaching. Research design: Employing a mixed-methods approach, we compare the first-year teaching of two groups of individuals with secondary science certification, one of which comprises graduates from a practice-embedded preparation program, and the other graduates from programs that did not feature practice-embedded preparation. A total of 116 science lessons taught by 41 first-year teachers were analyzed, focusing on the quality of student opportunities to learn (OTL) observed during the lessons. Research questions: This study sought answers to two research questions: 1) What are the characteristics of students' OTL from first-year teachers, one group of whom learned a set of core instructional practices during their preparation program and the other group of whom were not exposed to core practices? 2) Who provides opportunities for students to engage in meaningful disciplinary practices as outlined in the Next Generation Science Standards, during the first year of teaching, if any? How did they create such opportunities? Findings: Independent-sample t-tests showed that there are significant mean differences between the two groups (t=3.1~8.9; p
