Not only children but also adolescents and adults encounter great difficulties in learning to reason proportionally. Despite these difficulties, research increasingly shows that proportional reasoning emerges early, before it is being instructed in school. There have however been very few attempts to stimulate this early emerging ability. The aim…

This study examined bias reduction in the eight nonequivalent comparison group designs (NECGDs) that result from combining (a) choice of a local versus non-local comparison group, and analytic use or not of (b) a pretest measure of the study outcome and (c) a rich set of other covariates. Bias was estimated as the difference in causal estimate…

Prior studies have shown the efficacy of computer-based cognitive training programs in improving cognitive and academic functions in children diagnosed with a specific learning disorder (SLD). However, these studies often focused on center-based approaches without considering the involvement of parents or the inclusion of home-based tasks in…

The objective of the study was to analyze changes in motivation in physical education students during a school year, as well as changes in their intentions to be physically active. The participants were 830 Spanish physical education students (M[subscript age] = 13.86, range = 11-17 years) attending 10 secondary schools in northern Spain. The…

Phonological awareness (PA) and alphabet knowledge (AK) are two of the strongest predictors of reading acquisition, and evidence shows that many New Zealand children are entering school with low levels of emergent literacy (EL) skills. The current research showed that four-year-old children identified as having low levels of EL, who participated…

How to enhance the transfer of training remains an important question, and to some extent, post-training interventions can provide an answer. The purpose of this study was to validate inconclusive findings on the effectiveness of two post-training transfer interventions. This study used Solomon four-group design to filter out the effects of…

Inhibitory control plays a crucial role in cognitive functioning. We aimed to investigate the efficacy of a program for attentive rehabilitation of inhibition and selective attention (PARISA), on inhibitory control in preschool children. Thirty preschool children, (10 girls) aged six were randomly assigned to the two control and intervention…

The effectiveness of a mindset intervention in secondary vocational education and training was investigated. Students (n = 55) enrolled in a mathematics course participated in an online mindset intervention for a period of 10 weeks. Both pretest and posttest scores on mindset and mathematics results were compared with students who did not get a…

In typical development, emergent literacy skills predict successful reading abilities. Code-related literacy skills may include letter knowledge, print concepts, early writing and early phonological awareness. Meaning-related literacy skills may include lexical and grammatical ability, story retelling and comprehension. Children with ASD (autism…

This study examined the effect of a 10-week activity tracker, companion social website, and text messaging intervention on body mass index (BMI), body fat percentage, physical fitness, and physical activity (PA) self-efficacy of children. Children (n = 98) were assigned to one of three groups: activity tracker group, text messaging group, and…

Dementia patients have various caregiving needs, which can be serious sources of stress for their families. The increasing numbers of dementia patients and their families mean that new interventions are required to help families provide these complex caregiving needs. Facilitators of dementia-family support programs struggle to provide various…

School-based social and emotional learning (SEL) programmes represent a practical method of improving social and emotional well-being in students. To date, however, what is less well understood is why a theoretically sound, appropriately administered, engaging universal SEL programme may be more effective for some children over others. In the…

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.…

Many studies have shown that children with Autism Spectrum Disorders show lack of skills using social and communication skills. However, they understand, assimilate and retain better information using virtual aids. Therefore, the objective of this study has been to assess the effectiveness of an augmented reality training program based on visual…
