In this article, an overview is given of four methods to perform factor score regression (FSR), namely regression FSR, Bartlett FSR, the bias avoiding method of Skrondal and Laake, and the bias correcting method of Croon. The bias correcting method is extended to include a reliable standard error. The four methods are compared with each other and…

In the present chapter, we review the evidence for several principles that are especially promising for improving mathematics instruction. Using the classification scheme proposed by Koedinger et al. (2013), we begin with principles that focus on improving memory and fluency: scaffolding, distributed practice, and feedback. We then move to worked…

Missing data are a common occurrence in survey-based research studies in education, and the way missing values are handled can significantly affect the results of analyses based on such data. Despite known problems with performance of some missing data handling methods, such as mean imputation, many researchers in education continue to use those…

Error-correction strategies are essential considerations for behavior analysts implementing discrete trial training with children with autism. The research literature, however, is still lacking in the number of studies that compare and evaluate error-correction procedures. The purpose of this study was to compare two error-correction strategies:…

We compared the effectiveness of three training procedures, echoic and tact prompting plus error correction and a cues-pause-point (CPP) procedure, for increasing intraverbals in 2 children with autism. We also measured echoic behavior that may have interfered with appropriate question answering. Results indicated that echoic prompting with error…

There have been many discussions of how Type I errors should be controlled when many hypotheses are tested (e.g., all possible comparisons of means, correlations, proportions, the coefficients in hierarchical models, etc.). By and large, researchers have adopted familywise (FWER) control, though this practice certainly is not universal. Familywise…

Most studies that have investigated the effects of instruction on the SLA of specific grammatical features have focused on intentional learning. This study investigated incidental acquisition by comparing the relative effects of two types of instruction--comprehension-based instruction (CBI) and production-based instruction (PBI)--on young…

This study attempted to determine whether giving lower performing tutors preferential instruction over their higher performing tutees before they engage in peer tutoring sessions may help increase the reading achievement for these lower performing tutors. The preferential instruction consisted of giving adult-delivered instruction in a targeted…

This paper presents a critical analysis of two recent studies on error correction, Ellis, Sheen, Murakami, and Takashima (2008) and Bitchener (2008) and argues that neither study constitutes evidence for error correction based on discussion of the comparability of participants, design issues, and analysis flaws in both studies. The paper further…

This study compares teachers' language use and covert language attitudes in primary and secondary state education in Cyprus. The Ministry of Education and Culture encourages the systematic use of Standard Modern Greek in the formal learning environment of the classroom. Yet, our class observations and teacher interviews demonstrate that the Greek…

Background: Children who have a combination of language and developmental disabilities with autism often experience major difficulties in learning relations between objects and their graphic representations. Therefore, they would benefit from teaching procedures that minimize their difficulties in acquiring these relations. This study compared two…

Fluency has been identified as an important outcome of effective reading instruction, and intervention packages utilizing the method of repeated readings have been shown to improve oral reading fluency. In order to improve the efficiency of these intervention packages, more research is needed on the effectiveness of small group reading…

In January 2009, in the last week of the Bush Administration, the U.S. Department of Education (ED), upon orders from the departing political appointee staff, published the final report in a long running National Evaluation of Upward Bound (UB). The study was conducted by the contractor, Mathematica Policy Research. After more than a year in…

The purpose of this study was to compare two oral reading fluency treatments (repeated readings and phrase drill error correction) which differ in the way they prompt student responding. Repeated readings (RR) and phrase drill (PD) error correction were alternated with a baseline and a reward condition within an alternating treatments design with…

In Skinner's (1957) conceptual analysis, the process of self-editing is integral to the dynamic complexities of multiply determined verbal behavior, but the analysis has generated little in the way of an experimental analysis. The majority of scientific work on self-editing has taken place within linguistics and cognitive psycholinguistics. Here…
