We present an aggregation scheme that increases power in randomized controlled trials and quasi-experiments when the intervention possesses a robust and well-articulated theory of change. Intervention studies using longitudinal data often include multiple observations on individuals, some of which may be more likely to manifest a treatment effect…

With the increasing availability of technology and the emphasis on science, technology, engineering, and mathematics education, there is an urgent need to understand the impact of technology-mediated mathematics (TMM) interventions on student mathematics outcomes. The purpose of this study was to review studies on TMM interventions that target the…

Eighth grade math students must pass a standards based test to be promoted to the next grade. Students who were at risk of failing the state's annual test faced impending retention. The purpose of this quasi-experimental study was to see if an intensive nine-week (55 min per day) remedial Math Connection (MC) class for 67 suburban, eighth grade…

The specific problem that initiated this study was a continually high percentage of students not passing the mathematics section of the state mandated end of course assessment. The purpose of this study centered on determining whether or not laptop interventions, directed towards increasing student success on high stakes standardized assessments…

The increasing numbers of ELL and bilingual students in high schools, their high dropout rate, their low performance on standardized tests, and their low representation in STEM and gifted programs make urgent the need to focus on productive and effective instructional techniques to teach math to ELL/bilingual students in ways that motivate them to…

Objective: Suicide remains a pressing issue for college communities. Consequently, gatekeeper trainings are often provided for staff. This study examines the effect of one such program, Applied Suicide Intervention Skills Training (ASIST). Participants: 51 college employees received ASIST in August of 2014 and were compared to 30 wait-list control…

Students with elevated levels of risk require targeted Tier 2 behavioral interventions that are efficient and effective to prevent the need for more intensive, special education supports. Although Tier 2 is a critical component of multi-tiered systems of support, a paucity of research exists regarding how best to provide evidence-based Tier 2…

This paper describes the mixed methodology evaluation of the Own-Voice Intensive Phonics (OVIP) programme with 33 secondary students with persistent literacy difficulties. The evaluation involved a quasi-experimental evaluation in which 33 students in years 7-9 in four schools used OVIP over an 8 week period and were monitored at three times for…

The Teaching for Transformative Experience in Science (TTES) model has shown to be a useful tool to generate learning and engagement in science. We investigated the effectiveness of TTES for facilitating transformative experience (TE), learning, the development of topic interest and transfer of course concepts to other courses employing a…

We evaluated two experimenter-delivered, small-group word reading programs among at-risk poor readers in Grade 1 classes of regular elementary schools using a two-arm, dual-site-matched control trial intervention. At-risk poor word readers (n = 201) were allocated to either (a) Direct Mapping and Set-for-Variability (DMSfV) or (b) Current or…

In this study, the researchers aimed to design, plan and implement a Science, Technology, Engineering and Math (STEM) model to support Pre-K children's skills and knowledge in STEM as well as to improve Pre-K teachers' attitudes and professional skills to plan and integrate STEM concepts in their daily classroom activities. Four classrooms from a…

Dialogic reading is an evidence-based practice for preschool children who are typically developing or at-risk; yet there is limited research to evaluate if it has similar positive effects on the language and preliteracy skills of children with disabilities. This quasi-experimental study examined the effects of dialogic reading, with the…

The purpose of this quantitative, quasi-experimental study was to investigate the impact of a repeated reading fluency intervention focused on prosody, counterbalanced with an intervention focused on reading strategies. Both of these interventions were designed to promote feelings of achievement through participation in activities intended to…

Background: Despite the existence of evidence-based interventions for promoting mental health in children, the number of children at risk remains high. One of the reasons is that such interventions are not reaching specific groups at risk such as low socioeconomic status and ethnic minority groups. This study evaluated an adaptation of a…

The purpose of this study was to compare the results of a regression discontinuity design (RDD) with those of an experimental design of a tiered vocabulary intervention for children at risk for reading disability to determine RDD's feasibility as a research methodology for this type of study. Researchers reanalyzed an archival dataset of a…
