Efficacy Study
Seesaw ELD Promotes Language Acquisition in MLLs English learners are the fastest-growing demographic of students globally, making English language development (ELD) a high-priority area for many schools and districts. Currently, there are many models of English language instruction in practice. Some programs for ELD focus solely on English acquisition in isolation - learning English for the sake of learning English. However, recent research cited by WIDA shows that what is most important is for students to acquire language through content area knowledge - this helps English learners access grade-level appropriate content in different subjects (science, social studies, math etc.) while simultaneously learning English. This qualitative and quantitative study examines the effectiveness of Seesaw’s English Language Development (ELD) lessons for K-2 students. The results show: •
Improved Student Vocabulary and Word Usage
•
Increased Student Confidence and Engagement
•
Enhanced Teacher Satisfaction
Study Overview
Seesaw conducted a study in Fall 2024 to examine how K-2 teachers implemented Seesaw ELD lessons and measured the resulting impact on student learning. The study focused on 75 multilingual learners from five K-2 classrooms, each comprised of both multilingual and non-multilingual students. Data was collected through student pre- and post-assessments, teacher pre- and post-lesson surveys, and 30-minute post-study teacher interviews. The ELD lessons consisted of a set of activities intended to be taught throughout the week - these were implemented over a two-week period. Students engaged in one of three math or science ELD lessons, and their academic growth was evaluated.
Seesaw ELD Overview
Seesaw ELD is a supplemental K-5 English Language Development Program with over 480 ELA, Math, Science, and Social Studies lessons. Lessons are designed to help students develop an understanding of content and language concurrently, with academic content as a context for language learning. The content serves various ELD models found throughout schools across the globe. Our research foundation and pedagogical approach follow the WIDA Framework, Sheltered Instruction Observation Protocol (SIOP) Model, and state content standards. Seesaw ELD is validated as an ESSA Tier IV evidence-based intervention.
