The purpose of this study was to investigate the impact of computer-assisted instruction [CAI], incorporating virtual reality [VR], on the academic achievement of 6th-grade students in Science courses. The research employed a quasi-experimental design with a pre-test and post-test control group. Lessons in both experimental and control groups were…

Although integrating the history of science (HOS) into teaching has long been recommended in science education research, studies have revealed conflicting results on its effectiveness. These are mainly due to the need for more studies in this context. Therefore, this research aimed to explore the impact of HOS teaching on science process skills,…

Learning about components and processes of complex biological systems is challenging and requires abstraction through mediational tools such as text, visuals, models and visualisation experiences. The 'systems concepts' necessitate building coherent relations and anticipating consequences, requiring greater mediational support. This article…

The purpose of this study was to explore the performance of three groups of students, gifted hearing students (GH), average-ability hearing students (AH), and deaf students (DF) on mathematical ability. The sample consisted of a total of 167 students (91 males and 76 females). Deaf students came from the Al-Amal School (an inclusive school for…

Menarche is one of the most important transitions for women. Perceptions of menarche play an important role in this transition process and appear to be influenced strongly by culture. The purpose of this study was to examine perceptions of menarche among female adolescents in South Korea. Fifty-three female students' essays and drawings…

Young adolescents (N = 68) completed questionnaires concerning perceptions of neighborhood stress (i.e., high negative influences, low cohesion, and connectedness). Youth self-reported their own depressive symptoms and participated in a public speaking task designed to be moderately stressful. Increases in skin conductance in response to this…

Purpose: This study assessed phonological, lexical, and morphosyntactic abilities at 6th grade for a group of children previously tested at 2nd grade to address 4 questions: (a) Do children with cochlear implants (CIs) demonstrate deficits at 6th grade? (b) Are those deficits greater, the same, or lesser in magnitude than those observed at 2nd…

We set out to (i) assess the handwriting skills of signing deaf students, and (ii) examine the extent to which their text composition and spelling performances are linked to their handwriting efficiency. We asked 15 prelingually and profoundly deaf middle-school students (M = 15.18 years), all sign-language users, and a group of hearing students…

In this paper we focus on how South African students' ideas about the human body are constituted in their descriptions of three different scenarios involving the pathway of a sandwich, a painkiller and a glass of water through the body. In particular, we have studied the way in which the students transferred ideas between the sandwich and the…

Ichino and Moretti (2009) find that menstruation may contribute to gender gaps in absenteeism and earnings, based on evidence that absences of young female Italian bank employees follow a 28-day cycle. We find this evidence is not robust to the correction of coding errors or small changes in specification, and we find no evidence of increased…

The effect of physical activity (PA) and consequent influence on cognition within adult seniors has been widely published. However, there is a paucity of causal research relating PA and cognition to schoolchildren within an authentic setting. Also, little is known about the required intensity and dosage of PA to effect executive function (EF)…

Background: Physical activity and structural differences in the hippocampus have been linked to educational outcome. We investigated whether a curriculum-based physical activity intervention correlates positively with children's academic achievement, psychological well-being, health-related quality of life (HRQoL), fitness, and structural…

Schools located near to airports are exposed to high levels of noise which can cause cognitive, health, and hearing problems. Therefore, this study sought to explore whether this noise may cause auditory language processing (ALP) problems in primary school learners. Sixty-one children attending schools exposed to high levels of noise were matched…

Eighth graders (N = 136) were divided into two groups: students who had participated in at least one interscholastic sport and were classified as athletes (n = 73), and students who had not participated in interscholastic sports and were classified as nonathletes (n = 63). The mean grade point average (GPA) for each group and subgroup was computed…

Research on children with normal hearing shows that the word-processed narratives they produce are better than their hand-written narratives. Hearing children come to school with prior experience in narrating stories, and in school they learn to transfer this to written narrative form. However, children who are deaf and hard of hearing have less…
