Enrolment trends in school science education in Australia

Investigations were carried out to find the amount of science portrayed by terrestrial television in the UK and the public comprehension of that science as shown on television. UK terrestrial programming was derived from the Radio Times . Advertisement information was derived from UK terrestrial commercial television commercials. Public opinions were solicited by a survey of 200 members of the public ( n = 196). Science-based programming formed 5.36% of all terrestrial broadcasting time, with people watching an average of 1.75 science programmes per week (approx. 0.2% of programmes possible). 65% of all television advertisements were found to be science-based, although only 26% of advertisement categories were recognized as being science-based by the public. If interest in science is reflected in the amount of science programmes watched then the public are not interested in science. The lack of comprehension of the scientific basis of many advertisements is indicative of the lack of relevance of science education to people in modern society.     

A longitudinal assessment of adolescent student-athletes’ school performance

In Germany, extraordinarily talented student-athletes are offered the special school setting of elite schools of sport (ESSs). These schools seek to optimally adjust the daily affordances of athletic high-performance training with those of regular school education. The aim of the present analysis was to empirically explore whether elite student-athletes’ school grades develop differently than those of fellow students who dropped out of the ESS’s athletic program. One cohort of student-athletes (N?=?260) was tracked from the moment of their enrollment in the ESS until the end of lower secondary school (from school level 7 to 10). Multilevel modeling was used to analyze this longitudinal dataset. Elite student-athletes who manage to still meet their school’s athletic standards after class level 10 (n?=?158) came to their ESSs with better school grades in mathematics and German from primary school than program dropouts (n?=?102). Additional comparisons show that after class level 10, all ESS students’ school grades in mathematics and German were not significantly different from the federal state’s general average at schools without high-performance sport programs. Findings are interpreted against the background of the hypothesis that the system of high-performance sports tends to produce an instance of total commitment and that educational disadvantages for ESS student-athletes could follow as a consequence.     

Children as readers: what we learn from their conversations about reading

This article analyses a conversation about reading with three Year 8 students. Drawing on sociocultural theories of learning and elements of discourse analysis, it explores not only details of what the students read, but also how the process of the conversation itself shapes their perception of themselves as readers. Analysis of the data suggests that close attention to conversations such as these can affect our understanding of young readers and the reading practices in which they engage, in ways which may be valuable for classroom teachers of English.     

Effects of Aerobic Exercise on Cognitive Performance Among Young Adults in a Higher Education Setting

Purpose: Acute benefits of aerobic exercise on executive functioning have been reported frequently under laboratory conditions. However, to date, a beneficial effect on long-term memory has been less well supported and no data are available regarding nonlaboratory conditions in young adults. The aim of the current study was to investigate acute effects of aerobic exercise on cognitive functioning in a university classroom setting. Method: Using a cross-over design, 51 participants performed a bout of moderately intense running (RUN) and read an article while seated (CON). Afterwards, they completed free-recall tests, followed by a Flanker task and an n-back task. Results: Participants in the RUN condition compared with those in the CON condition showed shorter reaction time on the inhibition task, F(1, 50) = 5.59, p = .022, η² = .101, and recalled more words in the immediate- and delayed-recall tests, F(1, 50) = 8.40, p = .006, η² = .144. Conclusion: The present findings suggest that a moderately intense bout of aerobic exercise benefits verbal short-term and long-term memory as well as inhibitory control among students in a classroom setting.     

Poverty, Relationship Conflict, and the Regulation of Cortisol in Small and Large Group Contexts at Child Care

The purpose of this research is to explore the dynamics of cortisol regulation in the context of center-based child care by examining the impact of social context (large classroom vs. small group) and relationship quality with caregivers (conflict with mothers and teachers). We extend the research on children's physiologic stress system functioning in center-based child care by focusing on morning cortisol levels among young children living in poverty. While in high-quality center-based child care, children's cortisol levels decreased over the course of the morning—a result that contrasts with findings in previous research with middle-class children, for whom cortisol typically increased over the course of the day while attending center-based child care. Cortisol levels were further reduced when children were moved from a large classroom environment to a small group context. Relationship conflict with mothers and teachers moderated these effects. Children who had high conflict with their mother exhibited cortisol levels that remained higher (decreased less) over the course of the morning, and children who had high conflict with their teacher exhibited cortisol levels that remained higher (decreased less) in response to the small group context. These results indicate that high-quality child care has the potential to support reduced stress among children living in poverty, at least as indicated by adrenocortical activity.     

Displaced murder

Most suicide attempts appear to be impulsive and motivated by rage against another person. The author believes that publications of pro-suicide groups like EXIT or Hemlock serve a useful purpose for some terminally ill persons, although hospice care is a better approach for most dying patients. Potential suicides who are suffering from emotional stresses rather than terminal illnesses are best deterred by a personalized approach.     

A DGS gesture dictionary for modelling on mobile devices

Interactive or Dynamic Geometry System (DGS) is a tool that help to teach and learn geometry using a computer-based interactive environment. Traditionally, the interaction with DGS is based on keyboard and mouse events where the functionalities are accessed using a menu of icons. Nevertheless, recent findings suggest that such a traditional model of interaction has a steep learning curve and is inadequate to develop DGS for devices with multi-touch screens. Thus, we propose a new interaction model for DGS based on a gesture dictionary which enables the construction and manipulation of geometric objects without the need of accessing a menu of icons. The dictionary is divided into three types: (i) kernel gestures: which are the basis for defining gestures; (ii) navigation gestures: related to the manipulation and editing of geometric objects; and (iii) basic gestures of construction: to construct geometric objects. To validate our interaction model, a DGS for mobile device, GeoTouch, has been developed using the proposed dictionary. Usability tests were performed comparing GeoTouch with three other DGS for mobile devices. The results indicate that the GeoTouch interface has fewer usability problems than the other three DGS software and it is easier to learn and interact with.     

Learning through collaborative writing

This article looks again at the dynamics of reading, writing and telling stories. It argues that working collaboratively can motivate writers in ways which encourage them to redraft their work purposefully and explicitly in pursuit of particular creative effects. It exemplifies ways in which knowledge about language at word, sentence and whole text level can effectively be brought to bear as part of a holistic approach to writing.     

Are Prompts Provided by Electronic Books as Effective for Teaching Preschoolers a Biological Concept as Those Provided by Adults?

Research Findings: Prior research indicates that shared book reading is an effective method for teaching biological concepts to young children. Adult questioning during reading enhances children’s comprehension. We investigated whether adult prompting during the reading of an electronic book enhanced children’s understanding of a biological concept. Ninety-one 4-year-olds read about camouflage in 3 conditions. We varied how prompts were provided: (a) read by the book, (b) read by a researcher, or (c) given face to face by the researcher. There was an interaction between children’s initial vocabulary level and condition. Children with low vocabulary scores gave fewer camouflage responses than their high-vocabulary peers, and this effect was particularly pronounced in the book-read condition. Children’s executive function was also measured and discussed. Practice or Policy: Our findings indicate that under some circumstances electronic prompts built into touchscreen books can be as effective at supporting conceptual development as the same prompts provided by a coreading adult. However, children with low vocabulary skills may be particularly supported by adult-led prompting. We suggest that adult prompting be used to motivate children to test and revise their own biological theories. Once children have learned strategies for updating their concepts, electronic prompting may be useful for scaffolding children’s transition to using the strategies when reading alone.     

Do teachers’ knowledge and behaviour reflect their qualifications and training?

It is easier to collect data on teachers’ qualifications, experience, or training than to get a precise idea of their command of subject matter or their classroom behaviour. However, research consistently shows that “class effect” (the impact on a student of being in one class rather than another) on pupil performance is relatively high, especially in Africa, whereas the impact of qualifications, experience, or training on pupil learning is generally low. The purpose of this paper is to compare teacher academic qualifications and professional training on the one hand, with teacher test scores and behaviour on the other, showing the weak links between the former and the latter. What also emerges is the importance of certain external management-related factors such as the vastly reduced hours of effective learning time due to high rates of absenteeism and delayed term starts. Despite the importance of what really happens in the classroom, it remains difficult to measure the classroom dynamic reliably and accurately.
