Quality English and Science Teaching (QuEST)

Quality English and Science Teaching (QuEST) is a science curriculum intervention designed for middle grade English language learners and their English-proficient classmates. The program targets sixth grade students studying Living Systems and the Environment. QuEST combines inquiry-based science instruction (based on the BSCS approach emphasizing hands-on experimentation) with scaffolding techniques specifically designed for English language learners. Key features include consistent use of visuals (vocabulary illustrations and graphic organizers), activity previews, explicit vocabulary instruction of general and discipline-specific terms, and pairing of ELLs with English-proficient students as language models. The intervention is delivered face-to-face over 9 weeks in regular science classrooms. Materials include teacher guides with instructional charts, student guides with instructional charts, and hands-on science activity supplies. Teachers receive three training sessions plus ongoing weekly mentoring to learn how to encourage student expression, build on student experiences, and guide students to increasingly sophisticated understanding and language use.
