This study focused on examining the effects of early literacy intervention on the emergence and development of at-risk kindergartners' spelling. Spelling data were selected from Scanlon et al.'s (2005) study which demonstrated the efficacy of reading intervention in reducing the incidence of at-risk children who show reading difficulties…

Policy-makers are frequently interested in understanding how effective a particular intervention may be for a specific (and often broad) population. In many fields, particularly education and social welfare, the ideal form of these evaluations is a large-scale randomized experiment. Recent research has highlighted that sites in these large-scale…

This study was conducted as a follow-up analysis to two prior studies using existing data gathered in those original studies. In the current study, we focus on those preschoolers who received one of two interventions that varied in terms of the level of visual supports for grammatical elements (n = 22 of the original 34 participants). Utilizing…

This study explored the use of machine learning to automatically evaluate the accuracy of students' written explanations of evolutionary change. Performance of the Summarization Integrated Development Environment (SIDE) program was compared to human expert scoring using a corpus of 2,260 evolutionary explanations written by 565 undergraduate…

Traditionally, modeling student retention has been done by deriving student success predictors and measuring the likelihood of success based on several background factors such as age, race, gender, and other pre-college variables, also known as the input-output model. Increasingly, however, researchers have used mediating factors of the student…

Repeated Reading is a common reading intervention that has been used to help students read fluently since 1979. There are many variations of Repeated Reading that have been investigated and found to be effective. However, there is a relative research deficit on the effectiveness of software programs for administering Repeated Reading. This…

The purpose of my study was to evaluate the relationship between classroom process quality and child language and academic outcomes from the beginning of the pre-kindergarten year to the beginning of the kindergarten year for one cohort of children participating in a state-funded pre-kindergarten program in South Carolina. Data for my study were…

This study investigated the effect of a large group narrative intervention on diverse preschoolers' narrative language skills with aims to explore questions of treatment efficacy and differential response to intervention. A quasi-experimental, pretest/posttest comparison group research design was employed with 71 preschool children. Classrooms…

The summer school sessions that colleges offer their undergraduates are sometimes considered supplementary activities and are rarely perceived as central to a college's mission or effectiveness. However, analyses of college transcript data that tracked a nationally-representative sample of undergraduates for several years and through multiple…

Automated scoring by means of Latent Semantic Analysis (LSA) has been introduced lately to improve the traditional human scoring system. The purposes of the present study were to develop a LSA-based assessment system to evaluate children's Chinese sentence construction skills and to examine the effectiveness of LSA-based automated scoring function…

As part of the National Science Foundation Science Literacy through Science Journalism (SciJourn) research and development initiative (http://www.scijourn.org; Polman, Saul, Newman, and Farrar, 2008) a quasi-experimental design was used to investigate what impact incorporating science journalism activities had on students' scientific literacy.…

This article investigates several questions regarding the impact of different item formats on measurement characteristics. Constructed response (CR) items and multiple choice (MC) items obviously differ in their formats and in the resources needed to score them. As such, they have been the subject of considerable discussion regarding the impact of…

The purpose of this study was to determine if implementing a specific collaborative structure would create effective teacher teams that in turn would lead to improved student achievement. An effective team can be viewed as one that uses collaboration to increase its knowledge and improve its practices. The structure that was implemented during…

The 2003 National Assessment of Adult Literacy (NAAL) assessed the English literacy skills of a nationally representative sample of more than 19,000 U.S. adults (age 16 and older) residing in households and correctional institutions. NAAL is the first national assessment of adult literacy since the 1992 National Adult Literacy Survey (NALS). The…

Practitioners working closely with second language (L2) writers in the US recognize at least two types of L2 students: international (IL2) and Generation 1.5 (G1.5) students. Some argue that specific differences in each group's writing performance are evident (cf. Harklau, 2003; Reid, 2006); however, investigations into observable and measurable…
