This paper introduces a simple, quotient effect size, termed (for 'quotient'), suitable for reporting on the effectiveness of educational interventions. The quotient effect size for a pre-test-post-test design is defined as the gain score (i.e. post-test minus pre-test) for the intervention group, divided by the gain score for the control group.…

Teachers can use a variety of classroom management practices to help foster a classroom environment in which all students can learn. "Good Behavior Game" is a specific classroom management strategy that aims to improve social skills, minimize disruptive behaviors, and create a positive learning environment. Teachers place students into…

Because standardized tests in science are not given to PreK-3 students in Ohio, this report examined the longitudinal effects of learning from a teacher who had participated in the NURTURES professional development program. Specifically, it looked at the effects on students' mathematics and reading learning in grades 2-5 and science learning in…

Rigorous evidence of program effectiveness has become increasingly important with the 2015 passage of the Every Student Succeeds Act (ESSA). One question that has not yet been fully explored is whether program evaluations carried out or commissioned by developers produce larger effect sizes than evaluations conducted by independent third parties.…

Parent training (PT) is widely used with families of children with autism spectrum disorder (ASD), and its benefits for young children and their parents have been documented. However, no reviews have examined the use of PT within interventions delivered to older children with ASD or investigated the added benefit of including a PT component in…

Online instruction, including online instruction that is blended with traditional in-person instruction, offers students more flexibility in the timing of their coursework and may deepen students' understanding of the material. By leveraging online courseware, colleges have the potential to expand college access, reduce costs, recruit a more…

Early adolescence is a developmental stage characterized by changes in reasoning, social cognition, and desire for autonomy in youth aged 11-14 (or grades 6-8). This period is also associated with heightened impulsivity and risk-taking that has been linked to school-related challenges such as antisocial behaviors and declining grades. Character…

This paper reviews prior research to assess the effectiveness of Title I in closing the achievement gaps of disadvantaged students vis-à-vis their non-disadvantaged counterparts. A research synthesis approach is adopted to summarize national assessments of Title I conducted between 1966 and 2011. These analyses are supplemented by the authors'…

This meta-analysis provides an extensive and organized summary of intervention studies in education that are grounded in motivation theory. We identified 74 published and unpublished papers that experimentally manipulated an independent variable and measured an authentic educational outcome within an ecologically valid educational context. Our…

The recently reported i3 Scale-Up of Reading Recovery (May et al., 2015) found an effect size of +0.69 in favor of Reading Recovery compared to the control group. We discuss four issues: (a) many of the lowest achieving students were excluded from participation in Reading Recovery; (b) the control group received a range of different experiences;…

This systematic review examines train the trainer (TTT) effectiveness trials of behavioral interventions for individuals with autism spectrum disorder (ASD). Published methodological quality scales were used to assess studies including participant description, research design, intervention, outcomes, and analysis. Twelve studies including 9 weak…

We have many reasons to invest in preschool programs, including persistent gaps in school readiness between children from poorer and wealthier families, large increases in maternal employment over the past several decades, and the rapid brain development that preschool-age children experience. But what do we know about preschool education's…
