ISPCAN Child Abuse Screening Tool Children's Version (ICAST-C): Instrument development and multi-national pilot testing

ObjectiveTo develop a child victimization survey among a diverse group of child protection experts and examine the performance of the instrument through a set of international pilot studies.MethodsThe initial draft of the instrument was developed after input from scientists and practitioners representing 40 countries. Volunteers from the larger group of scientists participating in the Delphi review of the ICAST P and R reviewed the ICAST C by email in 2 rounds resulting in a final instrument. The ICAST C was then translated and back translated into six languages and field tested in four countries using a convenience sample of 571 children 12–17 years of age selected from schools and classrooms to which the investigators had easy access.ResultsThe final ICAST C Home has 38 items and the ICAST C Institution has 44 items. These items serve as screeners and positive endorsements are followed by queries for frequency and perpetrator. Half of respondents were boys (49%). Endorsement for various forms of victimization ranged from 0 to 51%. Many children report violence exposure (51%), physical victimization (55%), psychological victimization (66%), sexual victimization (18%), and neglect in their homes (37%) in the last year. High rates of physical victimization (57%), psychological victimization (59%), and sexual victimization (22%) were also reported in schools in the last year. Internal consistency was moderate to high (alpha between .685 and .855) and missing data low (less than 1.5% for all but one item).ConclusionsIn pilot testing, the ICAST C identifies high rates of child victimization in all domains. Rates of missing data are low, and internal consistency is moderate to high. Pilot testing demonstrated the feasibility of using child self-report as one strategy to assess child victimization.Practice implicationsThe ICAST C is a multi-national, multi-lingual, consensus-based survey instrument. It is available in six languages for international research to estimate child victimization. Assessing the prevalence of child victimization is critical in understanding the scope of the problem, setting national and local priorities, and garnering support for program and policy development aimed at child protection.     

Adding omega-3 fatty acids to a protein-based supplement during pre-season training results in reduced muscle soreness and the better maintenance of explosive power in professional Rugby Union players

Evidence suggests that omega-3 fatty acid supplementation could reduce muscle soreness and maintain muscle function following eccentric exercise-induced muscle damage. The aim of this applied field study was to investigate the effectiveness of consuming a protein-based supplement containing 1546?mg of omega-3 polyunsaturated fatty acid (PUFA) (551?mg eicosapentaenoic acid (EPA) and 551?mg docosahexaenoic acid (DHA)) twice daily (FO) compared to a protein-based placebo (P) on muscle soreness, countermovement jump (CMJ) performance and psychological well-being in 20 professional Rugby Union players during 5 weeks of pre-season training. Players completed a 5-point-Likert soreness scale with 5 indicating “no soreness” and a questionnaire assessing fatigue, sleep, stress and mood each morning of training, plus they performed CMJ tests once or twice per week. Data were analysed using magnitude-based inferential statistics and are presented as percent beneficial/trivial/harmful. On day 35, there was a likely (% beneficial/trivial/harmful: 94/5/1) moderate (0.75, standardized mean difference (SMD)) beneficial effect of FO vs. P on the change in lower body muscle soreness compared with day 0 (FO: ?3.8?±?21.7%; P: ?19.4?±?11.2%). There was a likely (92/7/0) moderate (SMD: 0.60) beneficial effect of FO vs. P on CMJ performance (change from baseline to day 35, FO: +4.6?±?5.9%; P: ?3.4?±?8.6%). From day 20, a moderate beneficial effect of FO on fatigue was observed. In terms of practical relevance, the moderate beneficial effect of adding fish oil to a protein-based supplement on muscle soreness translated into the better maintenance of explosive power in elite Rugby Union players during pre-season training.     

Becoming Globally Competent Citizens: A Learning Journey of Two Classrooms in an Interconnected World

Globally competent people are aware of world issues, take perspective, are engaged and know how to communicate to different people. This article portraits a story of two kindergarten classrooms, one in the United States and the other in Greece, both working with culturally diverse children and, in the case of the American classroom, English Language learners. The teachers shared philosophical foundations reflected in their practice and discourse in the classroom as they took a learning journey through Harvard Project Zero’s Out of Eden Learn project. Out of Eden Learn serves as a platform to engage children from both settings in exploring their own neighborhoods, investigating contemporary global issues, and reflecting on how they as individuals fit into a broader geographical and historical context. Through meaningful hands-on experiences, the children in these two classrooms gained deep understandings of themselves and their surroundings, made personal connections and developed empathy as they heard stories of children around the world. In their learning journey, the two teachers used thinking routines to help the children slow down and observe the world around them. The experience not only helped the teachers comply with curriculum standards, but also allowed them to keep alive the children’s capacity to be curious and promote parental involvement. The children developed a sense of self-understanding and self-identity as a point of reference to develop perspective and understanding of other cultures.     

Hiding behind the camera: social learning within the Cooperative Learning Model to engage girls in physical education

Research suggests that girls are disengaged in physical education due to the ‘traditional’ way that it is taught, i.e. teacher-centred approaches with a primary focus on motor performance. In contrast, Cooperative Learning, a student-centred pedagogy focusing on learning in multiple domains, has had success in engaging girls in physical education. Furthermore, when cooperative group work has been combined with technology, student engagement with learning is heightened. This article discusses the use of Cooperative Learning and video cameras to bring about a positive change to the learning environment for girls who were identified as being disengaged in physical education. Two classes of adolescent girls were taught an eight-lesson unit of Basketball using Cooperative Learning. Students worked in learning teams, participating in different roles, such as a coach or a camerawoman, to help each other learn and to film video clips of their learning. Data collection included a teacher's reflective journal, post-lesson teacher analysis tool, student interviews and the analysis of learning teams' movies. Inductive analysis and constant comparison was used for data analyses. Findings suggest that the role of the coach and the camerawoman was pivotal to girls' engagement. Some girls only ‘fully’ participated in lessons when learning was within the social and cognitive domains, since they could ‘hide behind the camera’ and were not required to participate physically. We controversially suggest that, in order to engage girls in physical education, we may have to temporarily remove the physical domain of learning (at least for some girls) in order to positively affect their longer term engagement in the subject.     

Science vs. Sports: Motivation and Self-concepts of Participants in Different School Competitions

Competitions are discussed as a measure to foster students’ interest, especially for highly gifted and talented students. In the current study, participants of a cognitive school competition in science were compared to non-participants of the same age group (14–15) who either did not participate in any competition or who participated in a non-cognitive sports competition. The study focused on goal orientations and competence beliefs and analyzed outcomes as a foundation for further improvements of enrichment measures and competitions with regard to fostering students’ interest especially in science. The results showed considerable differences (and some unexpected similarities) between groups: Science competition participants were more learning goal oriented, had less performance avoidance goals, and showed less work avoidance than non-participants. Social self-concept was higher but was moderated by GPA. Considerable gender differences were found as well. These findings are discussed with regard to further research and possibilities for improvement of science competitions.     

Learning Through Reflection in Mathematics Teacher Education

This article is written from our perspective as both researchers and mathematics teacher educators, and describes how our knowledge has grown as we engage concurrently in both teaching and research. Reflection-on-action is a means for us of approaching the relationship between theory and practice that comes out of the development of our work as researchers and mathematics teacher educators. The article presents the different steps we have identified in the relationship between theory and practice during our professional development. In the discussion, we examine the whole sequence of steps showing what we have learnt. Afterwards, we use the sequence of activity of the reflective process as a framework in which we can operate and reflect about our own development.     

An epidemiological study of number processing and mental calculation in Greek schoolchildren

The aim of this study was to validate and standardize an instrument for the diagnosis of developmental dyscalculia (mathematics disorder) in a Greek population and to obtain relevant epidemiological data. We used the Neuropsychological Test Battery for Number Processing and Calculation in Children (NUCALC) in a community sample of 240 students ages 7 to 11 years from urban and rural schools. There were no differences between genders in arithmetical performance; however, the effects of grade and socioeconomic level were significant. Prevalence was higher in the rural than in the urban area. A cross-cultural comparison of the Greek data with those obtained with the same instrument in other countries in schoolchildren of the same age was performed.
