Collaborative Research: A Longitudinal Randomized Trial Study of Middle School Science for English Language Learners (Project MSSELL)

德克萨斯A M和萨姆休斯顿州立大学之间为期三年的合作研究项目的目标是提高中学西班牙语英语学习者（ELLs）的科学成就和学术英语水平。为了实现这一目标，项目MSSELL将进行一个为期两年的随机试验纵向评估增强标准为基础的科学课程模式，以前通过一个五年的纵向随机试验研究由美国教育科学研究所资助。该模式由五个主要部分组成：（a）英语语言习得策略纳入科学课程，（B）技术辅助教学，（c）双周教师专业发展，（d）家庭参与，（e）辅助专业人员与个别英语学习者合作。在第一年，该项目将完善和试点模型的基础上，从其以前的发展阶段和实施与K-3年级的学生学习。在第二年和第三年，增强模型将与五年级和六年级的学生一起实施和研究。

The goal of this three-year collaborative research project between Texas A&M and Sam Houston State University is to improve the science achievement and the academic English language proficiency of middle school Spanish-speaking English language learners (ELLs). To accomplish this goal, Project MSSELL will conduct a two-year randomized trial longitudinal evaluation of an enhanced standards-based science curriculum model previously developed through a five-year longitudinal randomized trial study funded by the Institute of Education Sciences of the U.S. Department of Education. The model consists of five major components: (a) English language acquisition strategies integrated into the science curriculum, (b) technology-assisted instruction, (c) bi-weekly teacher professional development, (d) family involvement, and (e) paraprofessionals in working with individual ELLs. In Year 1, the project will refine and pilot the model based on learnings from its previous developmental phase and implementation with K-3 grade students. In Years 2 and 3, the enhanced model will be implemented and studied with fifth and sixth grade students.
