Mathematics related affect turn from positive to negative during comprehensive school years worldwide. There is a clear need to find solutions to the problem. However, some gaps and problems appear in the methodologies and the common approaches used in the field. This article discusses five studies addressing affective development, challenges some…

In recent years, the regression discontinuity design (RDD) has gained widespread recognition as a quasi-experimental method that when used correctly, can produce internally valid estimates of causal effects of a treatment, a program or an intervention (hereafter referred to as treatment effects). In an RDD study, subjects or groups of subjects…

Prior research suggests that summer learning loss among low-income children contributes to income-based gaps in achievement and educational attainment. We present results from a randomized experiment of a summer mathematics program conducted in a large, high-poverty urban public school district. Children in the third to ninth grade (N = 263) were…

The goal of this action research is to increase student awareness of context clues, with an emphasis on student use of visual cues in making predictions. Visual cues in the classroom were used to differentiate according to the needs of student demographics (Herrera, Perez, & Escamilla, 2010). The purpose of this intervention was to improve…

Achieve3000 publishes a number of online literacy programs that differentiate lessons and activities based on student performance. Magnolia Consulting--an independent, third party evaluation firm--assessed Achieve3000 Solutions' impact on student learning during the 2014-15 school year. The researchers used a randomized control trial, where…

Computer-based multimedia presentations employing animated agents (avatars) can positively impact perceptions about engineering; the current research advances our understanding of this effect to pre-college populations, the main target for engineering outreach. The study examines the effectiveness of a brief computer-based intervention with…

A usability study was conducted by the Research and Innovation Network and Assessment Solutions Design to assess the usability of a drawing response interaction type. The Partnership for Assessment of Readiness for College and Careers (PARCC) commissioned a multi-part study to determine the viability of using the drawing response interaction on…

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.…

Two animations, one focused on the macroscopic phenomena and particulate conception of the three states of matter and the effects of heat on these states, and the other on solution formation and solubility were produced using Adobe Flash MX software. The first was designed for and tested on elementary school (3rd-5th grade) students. The second…

Animations were prepared using Adobe Flash MX and tested on elementary (3rd-5th grade) and secondary chemistry students. A pre- and post-test study was used to compare the learning gains of students who received the animations with those who received textbook reading time and discussion in class. The control and experimental groups were further…

This dissertation focuses on a key challenge facing developing countries intent on enhancing their human capital base--namely, the issue of quality. One of the chapters evaluates the effectiveness of the One Laptop per Child (OLPC) initiative in Nepal's primary and lower-secondary schools. Although the OLPC program is being heavily promoted in…

This paper presents a series of illustrative LEGO Mindstorms-based science and math activities, developed under an NSF GK-12 Fellows project, for elementary, middle, and high school grades. The activities, developed by engineering and science graduate Fellows in partnership with K-12 teachers, are grade appropriate, address pertinent learning…
