Students’ perceptions of the learning environment and attitudes in game-based mathematics classrooms

We investigated whether the introduction of games into college-level mathematics classes in the United Arab Emirates (UAE) was effective in terms of improving students’ perceptions of the learning environment and their attitudes towards of mathematics. A pre–post design involved the administration of English and Arabic versions of two surveys (one to assess students’ perceptions of the learning environment and the other to assess their attitudes) after modification to ensure their relevance for college-level mathematics students in the UAE. For a sample of 33 classes (352 students), eight of which (90 students) were exposed to mathematics games, students involved in mathematics games perceived statistically significantly more teacher support, involvement, personal relevance, enjoyment of mathematics lessons and academic efficacy.     

Exploring relationships among TPACK constructs and ICT achievement among trainee teachers

Teaching in the classroom today can no longer sustain the interest of students and be effective if the process involves traditional approach - teachers as sole provider of content information. In recent years technology has played a significant role in transforming education to more progressive and interactive activities. However the use of technology itself does not produce positive results in quality of learning and students’ achievement. Teachers must be competent in subject knowledge, pedagogical skills and technological know-how. The Technological Pedagogical Content Knowledge or TPACK as a conceptual framework can guide teachers to understand the complex relations between the six components of the model. There has been numerous studies on TPACK in international contexts beyond cultural and language boundaries. This paper examined recent studies on TPACK in various countries and reports findings from a study conducted with student teachers in the UAE.     

The role of the school climate in high school students’ mental health and identity formation: A South Australian study

The well‐documented increase in student mental health issues in Australia and growing recognition of the need for education to play a part in students’ identity formation prompted this study. The research reported in this article sought to identify specific elements of the school climate that were likely to influence the interplay of adolescent health and development and students’ identity formation. The aim was two‐fold. First, the study examined the relationships between students’ perceptions of the school climate and self‐reports of wellbeing, resilience and moral identity; and, second, the interrelationships between the three outcome variables were explored. Two surveys, one to assess students’ perceptions of features of the school climate, and another to assess students’ wellbeing, resilience and moral identity, were administered to 618 Year 11 students from 15 independent schools in South Australia. Structural equation modelling was used to investigate hypothesised relationships between students’ perceptions of their school climate and self‐reports of wellbeing, resilience and moral identity. Our results indicated statistically significant and positive relationships between school‐climate factors and each of the three outcome variables. Further, indirect relationships (mediated largely by resilience) were found between school‐climate factors and students’ wellbeing. Our findings could be used to guide schools in building tangible, purposeful environments that engender well‐balanced, positive, resilient citizens with strong moral identities.     

Adverse childhood experiences,health perception,and the role of shared familial factors in adult twins

To examine the relationship between adverse childhood experiences (ACE) and health perception in adulthood, and to explore the contribution of shared familial factors to these associations. Data were collected from 180 female twins (90 pairs) from the community-based University of Washington Twin Registry. Participants completed questionnaires including the modified ACE Questionnaire, Traumatic Life Events Questionnaire, McGill Pain Questionnaire-Short Form, and the SF-36. Mixed effects linear regression modeling investigated the effects of ACE on indices of health perception controlling for correlated twin data. Additional models examined the associations while controlling for the experience of physical and/or sexual abuse in childhood; within-twin pair models that inherently adjust for familial factors explored shared familial influences. After controlling for relevant demographic variables, more ACE was associated with worse perceptions of general health (p = .01) and vitality (p = .05) on the SF-36. After controlling for childhood physical and/or sexual abuse, the relationship between ACE and general health remained significant (p = .01) while vitality was no longer significant. None of the associations remained significant after accounting for the influence of familial factors. These results support previous findings on the negative link between ACE and perceived health in adulthood. The detrimental effects of ACE on vitality may be accounted for by the experience of childhood physical and/or sexual abuse. Shared familial factors might play a partial role in the relationship between ACE and health perception. Future research should further investigate the genetic and environmental mechanisms that may explain this relationship.     

Association of Prooxidant–Antioxidant Balance with Clinical and Laboratory Parameters and Its Relation to Different Drug Regimens in Polycystic Ovary Syndrome Women with Normal BMI

Polycystic ovarian syndrome is one of the most common hormonally leading cause infertility disorders. The effect of oxidant-antioxidant imbalance on disease progression has been studied in many disorders. The present study was aimed to evaluate prooxidant–antioxidant balance (PAB) in patients with polycystic ovarian syndrome compared to healthy subjects. We also studied the possible effect of treatment with available drugs on serum PAB. In this case–control study 100 polycystic ovary syndrome (PCOS) patients and 100 healthy individuals were enrolled in the study. The laboratory features of patients and controls like as serum LH and FSH concentration and hematological examinations were collected. PAB was evaluated by a colorimetric method. Serum PAB value was significantly higher before treatment compared to after treatment and healthy subjects. PAB values were also higher in subjects with irregular menstrual cycle compared to normal subjects. Our results represented that serum PAB values has an indirect significant correlation with serum LH concentration. We also found that drugs regimen containing spironolactone effectively reduced the serum PAB values. Our results showed that PCOS patients had increased level of PAB and treatment with spironolactone mainly decreases the level of serum PAB. Our results indicate that the measurements of PAB may be used as a potential laboratory marker for assessment of PCOS patients.
