The purpose of this report was to evaluate the Lalilo software program. This large-scale quasi-experimental study independently conducted by Lehigh University reported that K-1 students in schools using Lalilo increased their early literacy skills at a greater rate than students in similar schools that did not use Lalilo.

This independent quasi-experimental study conducted by WestEd reported that Lalilo had a large significant positive impact on students' oral reading fluency skills. This is an important outcome because fluency is both a critical component of literacy and a strong predictor of later reading success. Effects were particularly strong for students…

In a randomized trial that collects text as an outcome, traditional approaches for assessing treatment impact require that each document first be manually coded for constructs of interest by human raters. An impact analysis can then be conducted to compare treatment and control groups, using the hand-coded scores as a measured outcome. This…

Background and Context: Historically, women have been underrepresented in computer science. To address this gender gap, researchers advocate for high-quality computer science programs for early childhood. Objectives: This study examines gender differences in coding performance before and after implementing a 24-lesson visual programming curriculum…

There is a lack of research evaluating the effects of digital textbooks and digital apps on learning for early elementary school learners. Therefore, this study conducted a randomized controlled trial to evaluate how an iPad application for learning English as a foreign language impacted children's grammar understanding, satisfaction, persistence,…

We investigated spelling errors in English and Spanish essays by Spanish-English dual language learners in Grades 1, 2, and 3 (N = 278; 51% female) enrolled in either English immersion or English-Spanish dual immersion programs. We examined what types of spelling errors students made, whether they made spelling errors that could be due to…

This study investigated the application of an artificial intelligence (AI) coach for second language (L2) learning in a primary school involving 327 participants. In line with Community of Inquiry, learners were expected to perceive social, cognitive, and teaching presences when interacting with the AI coach, which was considered a humanized…

Problem-based learning (PBL) offers a powerful approach to engage students in meaningful learning experiences by connecting classroom content to real-world challenges. This Spotlight explores how PBL can be implemented across K-12 to foster critical thinking, collaboration, and problem-solving skills. From preparing students for the workforce…
