Enhancing Students' Understanding of Mathematics: A Study of Three Contrasting Approaches to Professional Support

This report provides evidence of the influence of professional development and curriculum on upper elementary students' understandings of fractions. Three groups of teachers and their students participated. Two groups implemented a fractions unit that emphasized problem solving and conceptual understanding. The Integrated Mathematics Assessment (IMA) group participated in a program designed to enhance teachers' understandings of fractions, students' thinking, and students' motivation. The Collegial Support (SUPP) group met regularly to discuss strategies for implementing the curriculum. Teachers in the third group (TRAD) valued and used textbooks and received no professional development support. Contrasts of student adjusted posttest scores revealed group differences on two scales. On the conceptual scale, IMA classrooms achieved greater adjusted posttest scores than the other two groups, with no differences between SUPP and TRAD groups. On the computation scale, contrasts revealed no differences between IMA and TRAD, although TRAD achieved greater adjusted scores than SUPP (p < 0.10). Our findings indicate that the benefits of reform curriculum for students may depend upon integrated professional development, one form exemplified by the IMA program.

Still keen and committed: piloting an instrument for identifying positive veteran teachers

ABSTRACT

Since the mid-1980s, the working lives of teachers has become an enduring research topic. Much research has focused on early-career teachers and is often reported from deficit positions, i.e. why they leave the profession. However, career trajectory studies have described a small cohort of veteran teachers who remain positive and committed to teaching. This article reports on the creation and piloting of an instrument designed to test whether this positive cohort can be empirically identified within a wider teaching population. Four constructs (experimentation, challenge, comfort and leadership) drawn from Huberman (1993), and Day and Gu (2007) formed the basis for an online pilot survey completed by 145 teachers. Exploratory and confirmatory factor analysis supported three of the four factors (experimentation, comfort, leadership), with challenge loading strongly with experimentation. Initial findings suggest the potential of the instrument in helping identifying positive veteran teachers within systems, as well as the voracity of the research approach. Examining and articulating how these veteran teachers maintain their positive outlook may prove valuable as many countries confront an ageing teaching workforce, increasing student numbers and difficulties in retaining experienced teachers, meaning those who remain will be expected to sustain their commitment for longer.     

Does Russia need sex education? The views of stakeholders in three Russian regions

Objective To investigate the attitudes of the main stakeholders towards the introduction of sex education in schools in Russia.

Design Qualitative semi-structured interview study.

Setting Altai Krai, Volgograd Oblast, Moscow, Russian Federation.

Participants One hundred and fifty-three interviews with Intersectoral HIV/AIDS Committee members, government officials responsible for HIV policies and interventions, non-governmental organisation and private-sector representatives.

Main outcome measures Perception of and attitudes towards the introduction of sex education in schools.

Results Ninety-one per cent of stakeholders welcomed the introduction of sex education in schools and emphasised its importance for a child's personal development, public health, sexually transmitted diseases and HIV/AIDS control, and pregnancy planning. The majority of respondents suggested providing different information for each age and grade. Despite the claimed support of interviewed policy-makers and main HIV stakeholders, there has been no action to introduce sex education. The majority of respondents were of the view that wider positive support through propaganda about health, sex and healthy lifestyle should be gained prior to introducing sex education in schools by addressing the stigma surrounding sexual issues.

Conclusions There was little opposition to the introduction of sex education in Russian schools expressed in our survey, but there are uncertainties regarding curriculum quality, teaching methods and the starting grade of teaching about sex, and there is a need to cover local sensitivities in the territories. These concerns could and should be addressed during curriculum design, development and programme implementation by the federal and local authorities. Wider involvement of educational specialists, peer-adults, health workers, celebrities and religious representatives in discussion of the curriculum could help prevent opposition to its implementation.

Contribution to knowledge Discussion of sex-related topics has been taboo in Russia and there has been little research into opinions on issues related to sex education. The contribution of this research is in gaining theoretical in-depth understanding of the attitudes of the interviewed stakeholders in Russia about the introduction of sex education in schools.

Halting the Summer Achievement Slide: A Randomized Field Trial of the KindergARTen Summer Camp

In this randomized field trial of KindergARTen Camp, a 6-week summer enrichment program in literacy and the fine arts, we analyzed the summer learning outcomes of 93 treatment and 35 control students from high-poverty schools in Baltimore, Maryland. This experiment offers evidence concerning the causal effect of the program on 5 measures of students' literacy achievement. We found treatment effects during the summer months that were of both practical and statistical significance on the Developmental Reading Assessment (DRA) and the Word List A assessments. In addition, results from surveys of KindergARTen Camp students, parents, and teachers revealed strong satisfaction with the program. We conclude by discussing the contextual factors that may have contributed to these results.     

Las matemáticas en primaria y secundaria en la década de los 90

El acelerado cambio del papel de las matemáticas en el mundo en general o en cada cultura en particular, supone una serie de desafíos y cambios correlativos en la enseñanza de las matemáticas. En este ya clásico informe, convertido en libro tras su discusión en un seminario internacional, se pasa revista a ambos procesos y se sacan consecuencias concretas para la educación y los educadores sobre el lugar y el modo de abordar las matemáticas en el cunículum escolar.     

Black Obsession: The All Blacks’ Quest for World Cup Success

This paper explores the growth and development of the ‘art of swimming’ amongst Victorian female professional natationists when the common belief was that ‘ladies’ were not physiologically or emotionally equipped to withstand the rigours of physical exertion. The question is posed as to whether ornamental swimming was a ‘respectable’ form of entertainment for females to undertake or was it just another manifestation of the passion for freak-shows much loved by all social classes in late-Victorian England. Media coverage of this popular form of entertainment often described its female exponents as ‘nymphs’ and ‘naiads’, terms taken from Greek mythology in order to legitimise an activity that had strong sexual overtones. In so doing, the consumption of recreational activities, as opposed to sport, by females provided a course of less resistance from the sporting proselytisers throughout the period, 1870-c1910. Thus, the female pioneers of natation were able to promote their various ornamental swimming activities through their efforts in a variety of aquatic venues throughout the country. Their popularity resulted in a whole phalanx of nymphs and naiads being encouraged to demonstrate their mystical feats for the gratification of predominantly male-dominated audiences. But more significantly, they served to promote swimming amongst the female population for their own edification as a respectable recreational pursuit.     

Assessing Sitting Across Contexts: Development of the Multicontext Sitting Time Questionnaire

Purpose: To describe the development and preliminary evaluation of the Multicontext Sitting Time Questionnaire (MSTQ). Method: During development of the MSTQ, contexts and domains of sitting behavior were utilized as recall cues to improve the accuracy of sitting assessment. The terms “workday” and “nonworkday” were used to disambiguate occupational and discretionary sitting. An expert panel evaluated content validity. Among 25 participants, test–retest reliability of the MSTQ items was assessed with intraclass correlation coefficients (ICCs). Convergent validity was assessed versus relative and absolute accelerometer-estimated sedentary time and activity log using Pearson (r) or Spearman (ρ) correlation coefficients where appropriate. Results: Pilot testing revealed Web-based MSTQ administration was rapid, scalable, and inexpensive. Most items in the MSTQ demonstrated acceptable reliability (ICCs>.70). Compared with accelerometer-estimated sedentary time relative to total wear time, the MSTQ exhibited a low correlation on workdays (r = .34) and a moderately high correlation on nonworkdays (r = .61). Conclusions: The systematic development of the MSTQ resulted in several improvements over previous tools and may serve as a model for purpose-driven questionnaire design. Additional validation is needed to conclusively determine the utility of the MSTQ.     

Season-of-birth bias in association football

In this longitudinal study, we assessed the frequency of birth dates for boys selected for the Football Association National School. Birthdays were divided into three periods of the year: January to April, May to August and September to December. We compared data over a 5 year period and concluded that there is indeed a bias towards selecting older children. Furthermore, analysis of separate data revealed a shift of bias when comparing two different start dates, namely September and January. Our findings show that the youngest children from the January start date (born September to December) are selected significantly more often than the youngest children from the September start date (born May to August). Interestingly, even when the influence of body mass was reduced, the selection bias towards the older players remained.
