Ageism at university: A comparative analysis of young and older adult students

ABSTRACT

This study undertakes a comparative analysis of the negative stereotypes of older persons described by young and older adult university students at the University of Castilla-La Mancha. This study is innovative in that it compares three analytical perspectives: the perception of young students (18–27 years); the perception of older adult students (50 years and above) regarding older persons (hetero-stereotypes); and, finally, the perception of older adult students with regard to themselves as part of the group of older adult students (self-stereotypes).

The sample is made up of 460 young students and 148 older adult students who completed the Questionnaire on Negative Ageing Stereotypes (QNAS), comprising three dimensions: health; character and personality; and social relationships and motivation. A statistical analysis was subsequently carried out using the independent samples t-test in the IBM Statistics 19.0 program.

Of note among the principal results is the low level of negative stereotypes reported among the groups studied, as well as the existence of significant differences in their means, which indicate that the negative stereotypes of the groups differed. The most stereotyped of the dimensions analyzed was character and personality. In contrast, the least-stereotyped dimension was that of social relationships and motivation. Finally, the dimension of health occupied an intermediate position. With regard to the three perspectives studied, the older adult group (hetero-stereotypes) was the most stereotyped, followed by the young students and, finally, the older adult students with reference to self-stereotypes.     

6-Minute Walk Test Performance in Young Children who are Normal Weight and Overweight

PURPOSE

The primary purpose of this study was to investigate 6-minute walk test (6MWT) performance in young children who were normal weight (NW) and overweight (OW).

METHODS

Seventy children, 5-9 years of age, participated in this study. The 6MWT was performed on an indoor walkway. Heart rate (HR), blood pressure (BP), and oxygen saturation (SaO₂) were measured. A self-reported physical activity questionnaire was completed by a parent/guardian. Data were analyzed with independent t tests, ANOVA, correlation analyses, and logistic regression.

RESULTS

The systolic BP values were higher in the children who were OW compared with their NW peers (resting mean 104.1 (8.9) mmHg vs. 97.5 (7.8) mmHg, P < 0.05; post-6WMT: mean 118.4 (10.78) mmHg vs. 109.9 (9.1) mmHg, P < 0.05). The SaO₂ values were lower in the children who were OW compared to their NW counterparts (resting: mean 97.2 (1.1) % vs. 98.0 (1.0) %, P < 0.05; post-6WMT: mean 96.8 (1.0) % vs. 97.7 (1.0) %, P < 0.05).

CONCLUSIONS

The children who were OW had higher systolic BP and lower SaO₂ levels at rest and post-6WMT. More research is needed to determine if these differences contribute to children who are OW having difficulty performing exercise.Key Words: obesity, children, exercise capacity     

Effects of aerobic and cognitively-engaging physical activity on academic skills: A cluster randomized controlled trial

ABSTRACT

This cluster randomized controlled trial (trial-number #) compares effects of two school-based physical activity interventions (aerobic vs. cognitively-engaging) on reading, mathematics, and spelling achievement; and whether effects are influenced by volume of moderate-to-vigorous physical activity and baseline achievement. Twenty-two primary schools participated, where a third and fourth grade class were randomly assigned to the intervention or control group. Intervention groups were randomly assigned to a 14-week aerobic or cognitively-engaging intervention, receiving four physical education lessons a week. Control groups followed their regular physical education program. Academic achievement of 891 children (mean age 9.17 years, 49.4% boys) was assessed with standardized tests before and after the interventions. Post-Test academic achievement did not significantly differ between intervention groups and control group. A higher volume of moderate-to-vigorous physical activity resulted in better post-test mathematics achievement in both intervention groups, and post-test spelling achievement in the cognitively engaging intervention group. Compared to the control group, lower achievers in reading performed better in reading after the cognitively-engaging intervention. A combination of moderate-to-vigorous physical activity and cognitively-engaging exercises seems to have the most beneficial effects. Future intervention studies should take into account quantitative and qualitative aspects of physical activity, and children’s baseline academic achievement.

The relationship among motor proficiency, physical fitness, and body composition in children with and without visual impairments

This study compares the motor skills and physical fitness of school-age children (6-12 years) with visual impairments (VI; n = 60) and sighted children (n = 60). The relationships between the performance parameters and the children's body composition are investigated as well as the role of the severity of the impairment. The degree of VI did not differentially affect the outcomes. Compared to their sighted peers, the children with VI scored lower on the locomotor and object control skills as assessed with the Test of Gross Motor Development-2, and the physical fitness (Eurofit) parameters of plate tapping, the standing broad jump, the modified 5 x 10-m shuttle run, and 20-m multistage shuttle run (20-MST). Their body mass and body fat indexes were inversely correlated with the standing broad jump and the 20-MST but positively correlated with handgrip strength. Moreover significant inverse correlations were found between their locomotor and object control skills on the one hand and plate tapping and the 5 x 10-m shuttle run on the other hand. Given the relatively high proportion (25%) of overweight/obese children within the VI sample, educators are recommended to promote health-related activities and help enhance motor skills in this population.     

Opportunities to analyse pupils’ learning within coursework on campus: a remaining challenge in teacher education

To support pupils’ learning, teachers must understand what and how their pupils have learned, and teacher education should teach candidates how to do this. This article reports on survey data (n = 270) from three programmes and observation data (N = 104 h) from six programmes, located in Norway, Finland and the US. It examines the candidates’ opportunities to analyse pupils’ learning within their coursework. The authors argue that such opportunities might constitute profound possibilities to examine the complexity of teaching and learning. However, the study finds that the candidates have few opportunities to analyse pupils learning and that the full potential of these opportunities is unrealized. The authors argue for increased, specific attention to pupils’ learning within teacher education coursework, through a pedagogy of teacher education informed by existing research on how to elicit pupils’ learning.     

The use of Museum Based Science Centres to Expose Primary School Students in Developing Countries to Abstract and Complex Concepts of Nanoscience and Nanotechnology

Nanotechnology is an emerging technology, and it is regarded as the basis for the next industrial revolution. In developing countries, nanotechnology promises to solve everyday challenges, such as the provision of potable water, reliable energy sources and effective medication. However, there are several challenges in the exploitation of nanotechnology. One of the notable challenges is the lack of adequate knowledge about how materials behave at the nanoscale. As nanotechnology is relatively new, the current generation of scientists have not had the opportunity to learn the fundamentals of the technology at an early stage. Young students who are at the primary school level may follow the same trajectory if they are not exposed to the technology. There is a need to lay a strong foundation by introducing nanoscience and nanotechnology to students at the primary school level. It is during the early stages of child development that students master basic concepts for life long learning. Nevertheless, many primary school children, particularly those in developing countries are missing the chance of learning about nanoscience and nanotechnology because it is regarded as being abstract and complex. In this paper, we argue that despite the complexity of nanoscience and nanotechnology, science centres can be used as one of the platforms for exposing young students to the discipline. We use a case study of a museum-based science centre as an example to illustrate that young students can be exposed to nanoscience and nanotechnology using tactile and hands-on experience. The early engagement of primary school children with nanoscience and nanotechnology is important in raising the next generation of scientists who are firmly grounded in the discipline.
