Shoulder pathologies among the adult population are increasing, causing a high concern in health-educational institutions. The aim of this research is to take a step further and to conduct a detailed study of the relationship between the application of Jackins technique and a postural education program for people affected by shoulder problems.…

Reliable, consistent assessment process that produces comparable assessment grades between assessors and institutions is a core activity and an ongoing challenge with which universities have failed to come to terms. In this paper, we report results from an experiment that tests the impact of an intervention designed to reduce grader variability…

Single-subject experimental designs have long been used in special education to evaluate the effectiveness of interventions for exceptional children. However, the design has not been used widely in gifted education. In this article, an overview of the main features of single-subject design is presented, and its potential for application in gifted…

This article examines the effectiveness of a software that supports formative assessment in real-time of learners' vocabulary knowledge through an interactive highlighting method. Students in a classroom are given a passage on their computer screen and asked to highlight the words they do not understand. This information is summarized on the…

In this article, we test an alternative approach to creating a counterfactual basis for estimating individual and average treatment effects. Instead of using control/comparison groups or before-measures, the so-called Counterfactual as Self-Estimated by Program Participants (CSEPP) relies on program participants' self-estimations of their own…

Reviewing the studies on differential susceptibility presented in this section, we argue that the time is ripe to go beyond correlational designs to differential susceptibility experiments. In such experiments, randomization prevents hidden moderator effects on the environment and guarantees the independence of moderator and outcome, while the…

This paper presents results from a randomized control trial in which approximately 1,000 OLPC XO laptops were provided for home use to children attending primary schools in Lima, Peru. The intervention increased access and use of home computers, with some substitution away from computer use outside the home. Beneficiaries were more likely to…

A word-length effect is often described in pure alexia, with reading time proportional to the number of letters in a word. Given the frequent association of right hemianopia with pure alexia, it is uncertain whether and how much of the word-length effect may be attributable to the hemifield loss. To isolate the contribution of the visual field…

To assess the efficacy of guided oral reading as a remedy for low-achieving readers, two experiments were conducted in the early grades of primary school. In the first, poor-reading students were randomly divided between two treatment groups and a control group. In treatment groups, the intervention was delivered one-to-one, either in a repeated…

Use of multivariate analysis (e.g., multivariate analysis of variance) is common when normally distributed outcomes are collected in intervention research. However, when mixed responses--a set of normal and binary outcomes--are collected, standard multivariate analyses are no longer suitable. While mixed responses are often obtained in…

Given scarce resources for evaluation, we recommend that education researchers more frequently conduct comprehensive randomized trials that generate evidence on how, why, and under what conditions interventions succeed or fail in producing effects. Recent experience evaluating a randomized need-based financial aid intervention highlights some of…

Program effectiveness reviews in education seek to provide educators with scientifically valid and useful summaries of evidence on achievement effects of various interventions. Different reviewers have different policies on measures of content taught in the experimental group but not the control group, called here "treatment-inherent"…

This study attempted to determine the influence of prior knowledge in mathematics of students on learner-interface interactions in a learning-by-teaching intelligent tutoring system. One hundred thirty-nine high school students answered a pretest (i.e., the prior knowledge in mathematics) and a posttest. In between the pretest and posttest, they…

Pupils' expectation-related errors oppose the development of an appropriate scientific attitude towards empirical evidence and the learning of accepted science content, representing a hitherto neglected area of research in science education. In spite of these apparent drawbacks, a pedagogy is described that "encourages" pupils to allow their…

Despite the importance of teacher efficacy, there has been little research on the effects of interventions intended to increase it. Thus, the present study considered the potential of Professional Development (PD) in enhancing teachers' beliefs about their teaching ability. The study was quantitative in nature and utilized the reliable survey…
