Project Activities
The P-SELL curriculum is a full year science curriculum designed to promote standards-based, inquiry-driven science learning and focuses on science instruction with ELL students to enhance understanding of science and acquisition of English language and literacy. To evaluate the efficacy of the P-SELL curriculum, this project will use a randomized experimental design in which all grade 5 classrooms in schools assigned to the treatment condition will use the P-SELL curriculum to teach science, while all grade 5 classrooms in schools assigned to the control condition will use their standard curriculum.
Structured Abstract
Setting
The setting for this study includes large urban and suburban school districts throughout Florida.
Sample
The study sample will consist of grade 5 teachers and their students from 64 schools. The schools in the sample will have diverse compositions of elementary students designated as limited-English proficient (LEP).
Intervention
The P-SELL curriculum is a full year science curriculum that includes a complete set of class materials, including the student book, teachers' guide, science supplies, and trade books related to science topics. The curriculum is designed to promote standards-based, inquiry-driven science learning. It focuses on science instruction with ELL students to enhance understanding of science and acquisition of English language and literacy by incorporating the following strategies into the curriculum: (1) strategies for literacy development (reading and writing) of all students; (2) language support strategies with ELL students; (3) linguistic scaffolding for ELL students during classroom discourse; and (4) drawing on students' home language as instructional support. The curriculum contains 16 chapters clustered under 4 science domains: Physical and Chemical sciences; Earth and Space sciences; Life and Environmental sciences; and Scientific Thinking. The curriculum is designed to be implemented 2 to 3 hours per week throughout the school year.
Research design and methods
The researchers will randomly assign 32 schools to the treatment condition and 32 schools to the control condition. Treatment schools will implement the P-SELL curriculum in all their Grade 5 classes for 3 years. During the first two years of implementation, teachers in the treatment group will receive professional development training, but during the third year of implementation, teachers will not receive additional professional development in order to assess the sustainability of the intervention.
Control condition
Teachers in the control condition will teach their grade 5 students using the standard curriculum in place at the school.
Key measures
Student achievement in science, the key outcome measure in the study, will be assessed by a researcher-developed science test, along with the state standardized science achievement test as part of school accountability.
Data analytic strategy
A three-level hierarchical linear model, with students nested within classrooms nested within schools, will be used to estimate the impact of the P-SELL curriculum on students' science achievement. Within this modeling framework, the moderating effect of ELL classroom composition will be examined to determine the extent to which the P-SELL curriculum has differential effects on science achievement across ELL groups.
