This study proposed to investigate the effectiveness of learning activities based on a conceptual change theoretical framework by embedding a peer instruction method with structured inquiry (PISI) on tenth grade students' understanding of force and motion concepts. This teaching method was compared to the existing traditional instruction (TI).…

Cognitive processes require a functional interaction between specialized multiple, local and remote brain regions. Although these interactions can be strongly altered by an acquired brain injury, brain plasticity allows network reorganization to be principally responsible for recovery. The present work evaluates the impact of brain injury on…

Introduction: Computers and other technological instruments in general have become a more common practice in our schools nowadays, and Computer-assisted instruction (CAI) has been recently provided in various formats from kindergartens on. It can help children at-risk for learning disabilities. Method: This study investigated the effectiveness of…

Previous work on statistical power has discussed mainly single-level designs or 2-level balanced designs with random effects. Although balanced experiments are common, in practice balance cannot always be achieved. Work on class size is one example of unbalanced designs. This study provides methods for power analysis in 2-level unbalanced designs…

This study examined the feasibility of using a dialogic book-reading intervention for 22-r41-month-old bilingual preschool children with expressive vocabulary delays. The intervention was provided in English and Spanish concurrently to an experimental group of six children, while six other children were in a delayed treatment control group. Thirty…

The objective of this study was to evaluate the effectiveness of a computer-assisted emergency preparedness course for school nurses. Participants from a convenience sample (52) of school nurses from New Mexico were randomly assigned to intervention or control groups in an experimental after-only posttest design. Intervention group participants…

Background: The "broken mirror" theory of autism, which proposes that a dysfunction of the human mirror neuron system (MNS) is responsible for the core social and cognitive deficits in individuals with autism spectrum disorders (ASD), has received considerable attention despite weak empirical evidence. Methods: In this electroencephalographic…

In this study, whether or not constructivist teaching of double-slit interference of light has a positive effect on the secondary school students' conceptual change is examined. An achievement test, a conceptual understanding test and semi-structured interviews were used as data collection tools in this mixed methods research. Experimental group…

Objective: Examine the impact of providing yogurt to women enrolled in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). Design: Randomized, controlled intervention trial. Setting: Two California WIC local agency sites. Participants: 511 pregnant, breast-feeding, or postpartum women. Intervention: Substitution of…

The objective of this study was to better understand the long-term effects of an improved model for cooperation on employment between rehabilitation professionals in vocational rehabilitation (VR). To compare these effects with those associated with the traditional model of cooperation. The study featured a group of patients who participated in a…

This study investigates the effects of two factors: the mode of problem-solving instruction (i.e. Web-based versus non-Web-based) and the level of academic achievement (i.e. high achievers versus low achievers) on students' problem-solving ability and biology achievement. A quasi-experimental design was used, in which the experimental group…

The expansion of digital technologies and the rapid changes they undergo through time face users with new cognitive, social, and ergonomic challenges that they need to master in order to perform effectively. In recent years, following empirical reports on performance differences between different age-groups, there is a debate in the research…

Inquiry-based instruction is gaining favor in college classrooms because it improves scientific skills as well as critical thinking. As we seek ways to improve science education, elementary school is increasingly becoming an embattled component because of decreased time spent on science during those years. The approach that elementary educators…

Background: Whereas preventive interventions for depressed mothers and their infants have yielded positive short-term outcomes, few studies have examined their long-term effectiveness. The present follow-up of a randomised controlled trial (RCT) is one of the first to examine the longer-term effects of an intervention for mothers with postpartum…

This study examined the impact of two interventions on body image, eating disorder risk and excessive exercise among 170 (65% female) trainee health education and physical education (HE & PE) teachers of mean (standard deviation) age 21.6 (2.3) who were considered an "at-risk" population for poor body image and eating disorders. In the first year…
