This paper introduces a new observation system that is designed to investigate students' and teachers' talk during literacy instruction, "Creating Opportunities to Learn from Text" (COLT). Using video-recorded observations of 2nd-3rd grade literacy instruction (N=51 classrooms, 337 students, 151 observations), we found that nine types of…

Past research indicates that teacher math anxiety is related to student outcomes and can be decreased through intervention. However, there is little research on this topic, partially due to a lack of math anxiety measures validated for use with practicing teachers. In this study of 399 elementary school teachers, we report on the construct…

We report the results of a pre-registered, cluster randomized controlled trial of a mathematics learning intervention known as interleaved practice. Whereas most mathematics assignments consist of a block of problems devoted to the same skill or concept, an interleaved assignment is arranged so that no two consecutive problems require the same…

Recent work in predictive modeling has called for increased scrutiny of how models generalize between different populations within the training data. Using interaction data from 69,174 students who used an online mathematics platform over an entire school year, we trained a sensor-free affect detection model and studied its generalizability to…

Spanish speakers in the United States are a steadily increasing population, up by 233% since 1980. Given the growing population of dual language learners (DLLs) and the large numbers of Spanish-speaking children enrolled in pre-kindergarten programs, addressing the educational needs of preschool-aged DLLs has become a national imperative.…

This paper explores challenges in starting, developing, and incorporating partnerships between secondary and postsecondary education sectors. Site visits data from high schools, districts, and colleges across six Florida counties is used to identify the types of challenges educators faced in various phases of partnerships. We provide empirical…

"UNISON" was an Investing in Innovation (i3) development grant funded by the Office of Innovation and Improvement, U.S. Department of Education to Take Stock in Children (TSIC), a state-wide, 501(c)(3) non-profit, private-public partnership in Florida. UNISON provided a whole school mentoring approach and focused on developing students'…

Scholars have long argued that individuals' beliefs influence their behaviors and the decisions they make throughout their lives. Focusing on beliefs as a cognitive construct, the purpose of this study was to identify several key beliefs about mathematics teaching and learning held by practicing elementary mathematics teachers. An iterative…

Understanding fractions is critical to mathematical development, yet many children struggle with fractions even after years of instruction. Fraction arithmetic is particularly challenging. The present study employed a computational model of fraction arithmetic learning, FARRA (Fraction Arithmetic Reflects Rules and Associations; Braithwaite, Pyke,…

Over half of community college students place into developmental education, resulting in significant financial costs. We extend previous research demonstrating that using placement tests to assign students into developmental courses results in frequent misplacement. We use Florida data to explore the extent to which students are misplaced into…

This study examined the predictive validity and classification accuracy of individual and group-administered screening measures relative to student performance on a year-end state reading assessment in two states. A sample of 321 students were assessed in the areas of word-level and text fluency, as well as reading comprehension in the fall of…

Well-designed digital games hold promise as effective learning environments. However, designing games that support both learning and engagement without disrupting flow is quite tricky. In addition to including various game design features (e.g., interactive problem solving, adaptive challenges, and player control of gameplay) to engage players,…

We study the usage of a self-guided online tutoring platform called Algebra Nation, which is widely by middle school and high school students who take the End-of-Course Algebra I exam at the end of the school year. This article aims to study how the platform contributes to increasing students' exam scores by examining users' logs over a three year…

The population of Spanish-speaking preschoolers in the United States continues to increase and there is a significant need to develop psychometrically sound early language and literacy screening measures to accurately capture children's ability in Spanish. In this paper, we describe the innovative design and calibration process of the new…

The "2016 Knowledge for Teaching Early Elementary Mathematics" (2016 K-TEEM) test measures teachers' mathematical knowledge for teaching early elementary mathematics. The 2016 K-TEEM is the third version of the K-TEEM (Schoen, Bray, Wolfe, Tazaz, & Nielsen, 2017). In this report, we present results of the first large-scale field test…
