We explored third- to fifth-grade children's friendship concepts in 20 autistic and 21 nonautistic students matched for mental age. Transcripts of semi-structured interviews were coded for definitions of friendship, friendship expectations, and friendship transgressions (i. e., violations of friendship expectations), and subjected to quantitative…

We set out to (i) assess the handwriting skills of signing deaf students, and (ii) examine the extent to which their text composition and spelling performances are linked to their handwriting efficiency. We asked 15 prelingually and profoundly deaf middle-school students (M = 15.18 years), all sign-language users, and a group of hearing students…

We published our first set of Connections Academy efficacy reports containing independently assured efficacy statements in 2018. We went on to build on that body of research, and updated our reporting with new findings in 2021. Our latest study compared Connections Academy students' state test scores in reading and math with students in…

When nonrandom treatments occur across sites, within-site matching (WM) is often desirable. This approach, however, can significantly reduce treatment group sample size and exclude substantively important subgroups. To limit these drawbacks, we extend a matching approach developed by Stuart and Rubin to a multisite study. We demonstrate the…

This study describes a strengths-based blended personalized learning model, the implementation of the model over a 4-year period, and the results of an impact study focused on measuring its effectiveness. The model includes many commonly-used features of personalized learning, including (a) competency-based progressions, (b) flexible learning…

This study examines the intermediate effects of a community-based college preparation program in a fast growth, high-needs exurban district in Texas. Participants and a matched group of nonparticipants were compared on a variety of academic and noncognitive measures. Findings indicate program participation is associated with higher scores on the…

Background: Research investigating language skills in school-aged children with non-syndromic cleft lip and/or palate is sparse. Past studies focus on younger populations, lack key comparisons to demographically matched control cohorts or explore language as a component of broader academic skills. Trends of existing studies suggest that affected…

Augmented reality is defined as a technology in which real world and virtual objects are combined with a simultaneous interaction. The aim of this study is to determine the effect of augmented reality use on students' achievement, misconception and course engagement. A (matched) quasi-experimental research design with both pretest and posttest…

The field of language teaching and learning is in dire need of replications of vocabulary and comprehension research with diverse populations of learners. We propose for replication one large-scale vocabulary intervention carried out successfully in a middle-school with monolingual and multilingual students. This study was carried out several…

The purpose of this study was to examine the effects of integrating Interactive Whiteboard (IWB) technology on middle school mathematics achievement in an urban school. Propensity score matching was used to create a comparable control group in order to isolate the effects of IWB technology on mathematics achievement. An initial experimental group…

The aim of this study is to develop the Web Based Expert System (WBES) which provides analyses and reports based on the cognitive processes of Renewed Bloom Taxonomy (RBT), and to put forward the impact of the supportive education provided in line with these reports, on the academic achievement and mastery learning state of the students. The study…

To understand the immediate impact of a university-school district partnership that places preservice teachers (both traditional undergraduates and graduate students in an initial licensure residency program) in a Professional Development School (PDS) model, this exploratory study reviewed data from yearly examinations required by the Kansas State…

Holding students back when they do not meet a specific attainment level is common practice in a lot of countries. However, this practice is not without controversy and recent studies point at the negative effects of grade retention, especially in the long-term. The majority of these studies focused on grade retention in primary education. In our…

No previous research has employed learning environments criteria in evaluating the effectiveness of the system of teacher certification sponsored by the National Board for Professional Teaching Standards. Because the litmus test of any professional development effort is the extent of the changes in teaching behaviours in participating teachers'…

This article evaluates the impact and cost-effectiveness of offering an innovative middle school model--the Sistema de Aprendizaje Tutorial (SAT)--to Honduran villages instead of traditional middle schools. We identified a matched sample of villages with either type of school and collected baseline data among primary school graduates eligible to…
