At the end of high school, teenagers must deal with the first life-changing decision of determining what to do after graduation. For these decisions, adolescents need to be able to make good choices. However, most schools have not yet implemented decision trainings into their curricula. A new intervention called "KLUGentscheiden!" was…

The purpose of this article is to describe a 40+ year journey during which researchers have endeavored to design and evaluate an integrated, empirically based reading intervention for secondary students and to chronicle the lessons learned as well as suggest future directions for this type of work. Initial development of the intervention began in…

In experimental evaluations of policy interventions, the so-called Bloom adjustment is commonly used to estimate the impact of the treatment on the treated. It does so by rescaling the estimated impact of the intention to treat--that is, the overall treatment-control group difference in outcomes for the entire experimental sample--by the…

I Can Succeed-Elementary School (ICS-ES) is the first social-emotional learning (SEL) program based on interpersonal psychotherapy for adolescents (IPT-A). We hypothesized that fourth graders participating in ICS-ES over two school years would show improvements in interpersonal/social, emotional, and academic functioning. 419 fourth-grade students…

The evaluation of intervention effects is an important objective of educational research. One way to evaluate the effectiveness of an intervention is to conduct an experiment that assigns individuals to control and treatment groups. In the context of pretest/posttest designed studies, this is referred to as a control-group pretest/posttest design.…

Objective: This study aims to evaluate the impact of a community development program meant to improve living standards of poor rural families through income generating activities (IGAs) based on conditional cash transfers (CCTs) in Doti, Nepal.

Whether discussing the process involved in positive youth development (PYD), articulating an approach (or philosophy) of youth programs associated with PYD, or enacting a program aimed at promoting PYD, ideas derived from relational developmental systems (RDS) metatheory are pertinent. Accordingly, we discuss the RDS metamodel and explain the…

The effectiveness of a peer-mentoring program was examined at a university in California. Previous studies suggest university peer mentoring might increase students' feelings of engagement, which can contribute to their retention. Pretest and posttest data were collected from 304 freshmen (mentored and nonmentored) during the fall of 2012 in a…

We conducted a 14-week experimental study of 2 versions of a relatively comprehensive RC intervention that involved 50 classroom teachers, 15 tutors, and 116 children drawn in equal proportions from grades 3 and 5 in 13 schools in a large urban school district. Students were randomly assigned in equal numbers to the two tutoring conditions and a…

The aim of this study was to evaluate the effectiveness of Neurological Impress Method (NIM) on reading fluency of students with learning disabilities in Amman, Jordan.

This study tested whether and how methods called 'Play Time/Social Time' and 'I Can Problem Solve' contribute to the improvement of social skills and the development of theory of mind (ToM) in children. The participants in the experiment were nearly 200 (N = 196) preschool children with low social functioning, with and without disabilities. The…

There are unique challenges to estimating causal effects of preschool for students with special needs that have not received attention in the literature. We revisit the Head Start Impact Study (HSIS) to illustrate that when and how special needs is defined has implications for the internal validity of and interpretation of special needs subgroup…
