ABSTRACT
Promoting Science among English Language Learners (P-SELL) is a fifth-grade curricular and professional development (PD) intervention aimed at improving the science achievement of all students, with particular focus on English language learners (ELLs). P-SELL consists of a comprehensive, stand-alone, yearlong curriculum for fifth-grade students and teachers, as well as PD workshops for teachers focusing on curriculum implementation. The P-SELL model employs a standards-based, inquiry-oriented, and language-focused approach delivered through educative curriculum materials and effective PD. Through a decade of research (2004-2015), P-SELL has evolved over three distinct stages of development, efficacy testing, and effectiveness testing. The three stages of P-SELL took place across multiple school districts in Florida where the fifth-grade state science assessment counted toward school accountability. After P-SELL concluded, two of the participating school districts continued its implementation through either district funding or external funding.
