A printed module should consist of media elements, namely text and pictures, which are self-instructional and could cater to the needs of the user. However, the typical platform of such visualization frequently overloads the limited working memory causing split attention and redundancy effects. The purpose of this study is to design and develop a…

Objective: This study assessed a Web-based cognitive-behavioral therapy (CBT) for maladaptive perfectionism, investigating perfectionism, anxiety, depression, negative automatic thoughts, and perceived stress. Participants: Participants were undergraduate students defined as maladaptive perfectionists through a screening questionnaire at an urban…

This study was conducted to investigate the effects of eco-schools on elementary school students' environmental literacy levels. Data of the study were gathered from 316 students enrolled to two elementary schools. One of the schools was determined as experimental group (n = 156) and students attending this school received eco-school application.…

Background: The purpose of this study was to investigate the kinematic and electromyography strategy used by individuals with intellectual disability to keep equilibrium during anterior-posterior balance on seesaws with different degrees of instability. Method: Six individuals with Down syndrome (DS) and six control group individuals (CG) balanced…

Attrition occurs when study participants who were assigned to the treatment and control conditions do not provide outcome data and thus do not contribute to the estimation of the treatment effects. It is very common in experimental studies in education as illustrated, for instance, in a meta-analysis studying "the effects of attrition on baseline…

In this study the authors test whether matching using intact local groups improves causal estimates over those produced using propensity score matching at the student level. Like the recent analysis of Wilde and Hollister (2007), they draw on data from Project STAR to estimate the effect of small class sizes on student achievement. They propose a…

In this paper the authors extend recent work on mediation in a multilevel setting and on causal inference under interference among units to develop a template for the mediation analysis of group randomized educational interventions. The present work will contribute to the literature on interference, in particular on interference in the context of…

The present paper describes the recruitment and site selection process that has been underway since January 2011, with particular emphasis on the use of Mahalanobis distance score to determine matched pairs of sites prior to randomization to treatment and control groups. Through a systematic winnowing process, the authors found that they could…

In this experiment, the authors sought to further examine the effects of pretests on later learning. Specifically, they were interested in if activating a correct mental representation on the pretest would improve later learning and if activating an incorrect representation would impair learning. Kindergarteners and preschoolers were split into…

The Great Recession from December 2007 to June 2009 is associated with a dramatic weakening of the labor market from which the labor market is now only slowly recovering. The unemployment rate remains stubbornly high and durations of unemployment are unprecedentedly long. I use data from the Displaced Workers Survey (DWS) from 1984-2010 to…

This research has been aimed to demonstrate the effects of dance education on preadolescent children. A total of 114 students (56 of whom in dance group/58 in control group) at preadolescent (aged 11 [plus or minus] 0.0 year) and adolescent (aged 14 [plus or minus] 0.0 year) stages participated in the research. Prior to dance classes a variety of…

This study presents the results of an efficacy evaluation of a web-based brief motivational alcohol prevention/intervention program called "Michigan Prevention and Alcohol Safety for Students" (M-PASS). Four on-line sessions providing individually-tailored feedback were delivered to first-year college students over 9 weeks. Non- and…

A randomized posttest-only control group experimental design was used to determine the effects of regulatory self-questioning on secondary-level career and technical education students' electrical circuit theory test scores. Students who participated in the self-questioning group were asked to answer a list of regulatory questions as they solved…

An intensive phonics-based intervention program for nine-year-old Swedish pupils with reading difficulties was performed. Pupils (N = 112) were randomly assigned to either an intervention or a control group. The training was tailored to the Swedish transparent orthography and designed for one-to-one-tutoring during twelve weeks. Previously,…

The present study examined the verbal learning performance and the semantic organization used by Greek reading-disabled readers as compared to a control group using a list-learning task. The sample consisted of 45 elementary school children with reading difficulties and 45 comparison children matched for age and gender. Tests of reading ability,…
