Time sampling: a methodological critique

Numerous developmental studies of social behavior employ an observational technique called time sampling. This technique is used to estimate the frequencies and proportions of time that actual behaviors occur and to measure group or individual differences. By contrasting time sampling to continuous sampling, we demonstrate that (a) time sampling is inaccurate for estimating actual durations or frequencies of behavior, and (b) resulting individual and/or group differences can change depending on whether time sampling or continuous sampling is used. Error rates are particularly high when the total bout lengths of the actual behaviors are short (as in mother-infant interactions) and/or when interval length is long. Because the majority of mother and infant behaviors are short in bout length (less than 60 sec), when percent error is the greatest, we suggest that alternative sampling methods that have proven validity be used in future studies (e.g., scan, point, or continuous sampling).     

The ‘Employer Engagement Cycle’ in Secondary Education: analysing the testimonies of young British adults

Work experience placements are mandatory in the UK for all young people aged 16–18 in education, and their employability effects and associated wage premia are well noted in the literature. Through Bourdieu’s lens, this article analyses and conceptualises a unique data set of reflective testimonies submitted in response to a YouGov survey of over one thousand young people. Different capitals are detected, their distributions are observed, and correlations with key variables such as social background and school type are reported. Emerging through young people’s perceptions of employer engagement is a complex web of human, social and cultural capital accumulation. Overlaps are frequent, with newly acquired forms of capital often activating others. We argue that because of the cyclical nature of employer engagement gains, benefits accumulate exponentially for some young people while leaving others increasingly detached from the capitals that are most important for labour market success.     

From here to there and back again: the story of a mother,her son,disability, and school choice

Nelly and her children live in Queensland, Australia. When it came time for her second youngest son to start school, Nelly was not prepared for the difficulty that she had enrolling him at the school of her choice. In spite of her son's disability, Nelly thought that it was natural that he would go to his local school with his sister. It is not surprising that she expected this, given the legal and policy endorsement of inclusive education that exists in the Queensland education system. What unfolded in Nelly's life as she pursued this enrolment is the subject of this article. This is the story of a mother who believed in and hoped for inclusive schooling for her son but who found herself caught in a series of events and experiences which ultimately led to the decision to transfer him into a special school. This is also the story of how, disillusioned and regretful, she went on to undo that decision. Told primarily in Nelly's own words, this narrative provides a deep insight into one mother's efforts to exercise her parental authority, the difficulties she encountered in trying to do so, and the consequences for her son.     

Factors Involved in the Implementation of Pedagogical Innovations Using Technology

This paper analyzes the factors involved in successful implementation of innovative pedagogical practices using ICT in ten Israeli schools. The research questions addressed are: 1. What is the configuration and intensity level of the various factors involved in the implementation of innovative pedagogical practices using ICT in schools? 2. Can a connection be identified between the level of intensity of the different factors affecting the innovation and the level of change in various domains of innovation (e.g., teacher role, student role, curriculum, and time and space configurations)? Data from ten case studies in Israeli schools were analyzed using the framework developed to measure the intensity of the factors involved in the innovation. Infrastructure, factors within the school, school climate and educational policy were found to be the most involved categories. These factors mostly affect aspects of the innovation related to teacher roles, instructional contents and teaching methods.     

What did schools experience from participating in a randomised controlled study (PLAY) that prioritised risk and challenge in active play for children while at school?

‘Risky’ play is an important component of play, which positively affects the cognitive, social and emotional development of children. However, a growing culture of ‘risk aversion’ may be limiting the degree of risk that children are allowed to encounter. We undertook qualitative interviews with eight schools to examine the acceptability of an intervention designed to increase risk and challenge in the school playground (e.g. more rough-and-tumble play and tree climbing). Schools were overwhelmingly positive about the approach and all enjoyed participating. Each school believed many benefits occurred from increasing risk and challenge within play, including better behaviour, improved cooperation between children and increases in physical activity. There were some challenges for schools, but these were generally research related, and all were viewed as acceptable. Indeed, schools found the process enlightening, and upon completion of the two-year intervention often viewed play in quite a different light.     

Reading ability and sensitivity to morphological relations

The morpho-phonological nature of English orthography is examined in this study of the relation between morphological sensitivity and decoding ability in the latter elementary grades. Children in grades three to six were required to distinguish derivationally-related word pairs (e.g., nature-natural) from foil pairs that are related in spelling but not in morphology (e.g., ear-earth). The materials included both transparently-related (i.e., the second word incorporated the pronunciation of the first, as in person-personal) and complexly-related word pairs (i.e., the second word involved some change in pronunciation, as in atom-atomic). Across two experiments, these items were presented in either oral or written form along with various tests of reading ability, intelligence and phonological awareness. The results indicate that children's recognition of derivational relationships improved with grade-level. As anticipated, there was also a significant association between sensitivity to derivational relatedness and decoding ability which remains significant even when the word pairs were orally presented and even when phonological awareness in taken into account. Both phonological awareness and sensitivity to morphological structure emerge as important factors in decoding skill in the later elementary grades.     

Age-ordered shirt numbering reduces the selection bias associated with the relative age effect

When placed into age groups for junior sporting competition, the relative differences in age between children leads to a bias in who is evaluated as being talented. While the impact of this relative age effect (RAE) is clear, until now there has been no evidence to show how to reduce it. The aim of this study was to determine whether the selection bias associated with the RAE could be reduced. Talent scouts from an elite football club watched junior games and ranked players on the basis of their potential. Scouts were allocated to one of three groups provided with contrasting information about the age of the players: (1) no age information, (2) players’ birthdates or (3) knowledge that the numbers on the playing shirts corresponded to the relative age of the players. Results revealed a significant selection bias for the scouts in the no-age information group, and that bias remained when scouts knew the players’ dates-of-birth. Strikingly though, the selection bias was eliminated when scouts watched the games knowing the shirt numbers corresponded to the relative ages of the players. The selection bias associated with the RAE can be reduced if information about age is presented appropriately.
