This study synthesized intervention studies focusing on instruction to improve fraction skills. Seventeen studies met the inclusion criteria: being published in English-language peer-reviewed journals or dissertations between 1975 and 2014, and targeting 3rd- through 12th-grade students struggling to learn mathematics. From the "Common Core…

Title I, Part A and Title II, Part A funds are provided to Houston Independent School District (HISD) through the 2002 reauthorization of the "Elementary and Secondary Education Act of 1965" (ESEA), also known as the "No Child Left Behind Act of 2001" (NCLB). ESEA was reauthorized in 2015 as the "Every Student Succeeds…

This mixed design study investigated the predictive and instructional uses of two different types of interim mathematics assessments given in two different districts. One district administered the same summative type of assessment three times a year, while the other district administered a different interim assessment after six-week intervals of…

High-quality measures of instructional practice are essential for research and evaluation of innovative instructional policies and programs, as well as for providing feedback to teachers and administrators. In this study, the authors examined whether using anchoring vignettes in web-based surveys improved the validity of teachers' self-assessments…

Mixed-aged (MA) classes are a common phenomenon around the world. In Sweden, these types of classes increased rapidly during the 1980s and 1990s, despite the fact that existing empirical support for MA classes is weak. In this paper, the effect of attending an MA class during grades 4-6 on students' cognitive skills is estimated. Using a unique…

This article discusses the heterogeneity in children's appropriation and use of the internet that make up contemporary digital divides. Based on a survey of Portuguese children in mandatory education (8- to 17-year-olds), it relies on multivariate statistical procedures to build a topological mapping of internet use patterns. Variations in digital…

We studied developmental trends in 5 important reasoning tasks that are critical components of the operational definition of rational thinking. The tasks measured denominator neglect, belief bias, base rate sensitivity, resistance to framing, and the tendency toward otherside thinking. In addition to age, we examined 2 other individual difference…

Research on factors that may promote engagement is hampered by the absence of a measure of classroom-level engagement. Literature has suggested that engagement may have 3 dimensions--affective, behavioral, and cognitive. No existing engagement scales measure all 3 dimensions at the classroom level. The Classroom Engagement Inventory (CEI) was…

Educators and policymakers have set a goal that all students graduate from high school ready for college and careers. A substantial body of research supports the idea that the path to college and career readiness begins well before middle and high school. In an earlier policy report, ACT examined the percentage of academically far off track…

Each year, the Houston Independent School District (HISD) offers a summer education program designed to assist students with a variety of instructional needs. The 2015 summer education program allowed students the opportunity to repeat required courses needed for promotion, to get ahead by taking required courses before the next school year, or to…

Teachers are in the perfect position to be an influential source of help to students with life and academic circumstances that inhibit them from staying on the path to graduation, but they often underestimate their role in helping students develop the resilience to do so. Re-engaging students in the learning process who are severely off the…

Robotics competitions for K-12 students are popular, but are students really learning and improving their STEM scores through robotics competitions? If not, why not? If they are, how much more effective is learning through competitions than traditional classes? Is there room for improvement? What is the best robotics competition model to maximize…

Background: Cluster-randomized experiments that assign intact groups such as schools or school districts to treatment conditions are increasingly common in educational research. Such experiments are inherently multilevel designs whose sensitivity (statistical power and precision of estimates) depends on the variance decomposition across levels.…

Title I, Part A and Title II, Part A funds are provided to Houston Independent School District (HISD) through the 2002 reauthorization of the Elementary and Secondary Education Act of 1965 (ESEA), also known as the No Child Left Behind Act of 2001 (NCLB). Both funds focus on enhancing student achievement: Title I, Part A provides supplemental…

Purpose: A mixed-methods approach, evaluating triple word-form theory, was used to describe linguistic patterns of misspellings. Method: Spelling errors were taken from narrative and expository writing samples provided by 888 typically developing students in Grades 1-9. Errors were coded by category (phonological, orthographic, and morphological)…
