Adolescent alcohol-use trajectories in the transition from high school

A cohort of 3300 students from high schools across Victoria, Australia, were surveyed regarding their patterns of alcohol consumption from mid-1993 to 1995. The first wave of data was collected halfway through the students' final year of school (year 12). Students were then resurveyed 3 months following school completion and on two subsequent occasions, each separated by 6-month intervals. Analysis of the four waves of data indicated that five longitudinal patterns (trajectories) characterized temporal trends in male and female alcohol use through the transition from high school. Stable non-use trajectories were evident for 17% of males and 16% of females. Trajectories of less than weekly use characterized 45% of females and 46% of males, and showed little tendency to escalate toward harmful use. Among those using alcohol on a weekly or more frequent basis in high school, with few exceptions, use continued with at least the same frequency, but the quantity of alcohol consumed tended to escalate over time toward harmful levels. Overall, findings indicate that patterns of alcohol use tend to be stable over time, and more frequent alcohol use during the final year of high school tends to precede potentially harmful alcohol use following high school. Encouraging those high school students who consume alcohol once per week or more often to use alcohol on a less than weekly basis may be a valuable yet neglected harm minimization strategy.

Multiple types of dieting prospectively predict weight gain during the freshman year of college.

The freshman year of college is a period of heightened risk for weight gain. This study examined measures of restrained eating, disinhibition, and emotional eating as predictors of weight gain during the freshman year. Using Lowe's multi-factorial model of dieting, it also examined three different types of dieting as predictors of weight gain. Sixty-nine females were assessed at three points during the school year. Weight gain during the freshman year averaged 2.1 kg. None of the traditional self-report measures of restraint, disinhibition, or emotional eating were predictive of weight gain. However, both a history of weight loss dieting and weight suppression (discrepancy between highest weight ever and current weight) predicted greater weight gain, and these effects appeared to be largely independent of one another. Individuals who said they were currently dieting to lose weight gained twice as much (5.0 kg) as former dieters (2.5 kg) and three times as much as never dieters (1.6 kg), but the import of this finding was unclear because there was only a small number of current dieters (N=7). Overall the results indicate that specific subtypes of dieting predicts weight gain during the freshman year better than more global measures of restraint or overeating.

The dietary, physical activity and sedentary behaviours of Victorian regional secondary school students

The aim of this study was to investigate the dietary, physical activity and sedentary behaviours of adolescents from four secondary schools in Warrnambool, regional Victoria. In 2004, a random sample of students (n=712), stratified by school year level, was generated from school enrolment databases and 443 students completed a lifestyle questionnaire. Twenty per cent of students were physically active for 60 minutes or more per day; 28 per cent used electronic media in free time for a maximum of two hours per day. Only seven per cent of students met these two Australian physical activity recommendations. Fruit, vegetables and dairy products were consumed every day by 39 per cent, 40 per cent and 71 per cent of students respectively; three serves per day of each of these foods are recommended for Australian adolescents. Compared with boys, girls were less physically active (p<0.001), consumed more fruit (p=0.011) and vegetables (p<0.001), but fewer dairy products (p<0.024). Seventeen per cent of students were overweight or obese; these students were less physically active than normal weight peers (p<0.018). The dietary, physical and sedentary behaviours of regional Victorian secondary school students in this study were inadequate when compared with Australian recommendations. Dietary and physical activity habits are still evolving in adolescence and unhealthy habits can still be changed.

A cluster-randomized controlled trial to reduce sedentary behavior and promote physical activity and health of 8-9 year olds : the transform-us! study

Background: Physical activity (PA) is associated with positive cardio-metabolic health and emerging evidence suggests sedentary behavior (SB) may be detrimental to children’s health independent of PA. The primary aim of the Transform-Us! study is to determine whether an 18-month, behavioral and environmental intervention in the school and family settings results in higher levels of PA and lower rates of SB among 8-9 year old children compared with usual practice (post-intervention and 12-months follow-up). The secondary aims are to determine the independent and combined effects of PA and SB on children’s cardio-metabolic health risk factors; identify the factors that mediate the success of the intervention; and determine whether the intervention is cost-effective.
Methods/design: A four-arm cluster-randomized controlled trial (RCT) with a 2 × 2 factorial design, with schools as the unit of randomization. Twenty schools will be allocated to one of four intervention groups, sedentary behavior (SB-I), physical activity (PA-I), combined SB and PA (SB+PA-I) or current practice control (C), which will be evaluated among approximately 600 children aged 8-9 years in school year 3 living in Melbourne, Australia. All children in year 3 at intervention schools in 2010 (8-9 years) will receive the intervention over an 18-month period with a maintenance ‘booster’ delivered in 2012 and children at all schools will be invited to participate in the evaluation assessments. To maximize the sample and to capture new students arriving at intervention and control schools, recruitment will be on-going up to the post-intervention time point. Primary outcomes are time spent sitting and in PA assessed via accelerometers and inclinometers and survey.
Discussion: To our knowledge, Transform-Us! is the first RCT to examine the effectiveness of intervention strategies for reducing children’s overall sedentary time, promoting PA and optimizing health outcomes. The integration of consistent strategies and messages to children from teachers and parents in both school and family settings is a critical component of this study, and if shown to be effective, may have a significant impact on educational policies as well as on pedagogical and parenting practices.

Expanding children's food experiences : the impact of a school-based kitchen garden program

Objective: Evaluate achievement of the Stephanie Alexander Kitchen Garden Program in increasing child appreciation of diverse, healthy foods.

Design: Comparative 2-year study.

Setting: Six program and 6 comparison primary schools in rural and metropolitan Victoria, Australia, matched for socioeconomic status and size.

Participants: A total of 764 children in grades 3 to 6 (8–12 years of age) and 562 parents recruited. Retention rates at follow-up included 85% children and 75% parents.

Intervention: Each week of the school year, children spent 45 to 60 minutes in a garden class and 90 minutes in a kitchen class.

Phenomenon of interest: Program impact on children’s willingness to try new foods, capacity to describe foods, and healthy eating.

Analysis: Qualitative data analyzed using inductive thematic analysis. Quantitative data analyzed using random-effects linear regressions adjusted for school clustering.

Results: Child and parent qualitative and quantitative measures (if never tried before, odds ratio 2.0; confidence interval, 1.06–3.58) showed increases in children’s reported willingness to try new foods. No differences in articulation of food descriptions (program vs comparison groups). Qualitative evidence showed that the program extended its influence to healthy eating, but this was not reflected in the quantitative evidence.

Conclusions and Implications: Findings indicate program success in achieving its primary objective, meriting further program research.

Effects of a free school breakfast programme on school attendance, achievement, psychosocial function, and nutrition: a stepped wedge cluster randomised trial

BACKGROUND: Approximately 55,000 children in New Zealand do not eat breakfast on any given day. Regular breakfast skipping has been associated with poor diets, higher body mass index, and adverse effects on children's behaviour and academic performance. Research suggests that regular breakfast consumption can improve academic performance, nutrition and behaviour. This paper describes the protocol for a stepped wedge cluster randomised trial of a free school breakfast programme. The aim of the trial is to determine the effects of the breakfast intervention on school attendance, achievement, psychosocial function, dietary habits and food security.

METHODS/DESIGN: Sixteen primary schools in the North Island of New Zealand will be randomised in a sequential stepped wedge design to a free before-school breakfast programme consisting of non-sugar coated breakfast cereal, milk products, and/or toast and spreads. Four hundred children aged 5-13 years (approximately 25 per school) will be recruited. Data collection will be undertaken once each school term over the 2010 school year (February to December). The primary trial outcome is school attendance, defined as the proportion of students achieving an attendance rate of 95% or higher. Secondary outcomes are academic achievement (literacy, numeracy, self-reported grades), sense of belonging at school, psychosocial function, dietary habits, and food security. A concurrent process evaluation seeks information on parents', schools' and providers' perspectives of the breakfast programme.

DISCUSSION: This randomised controlled trial will provide robust evidence of the effects of a school breakfast programme on students' attendance, achievement and nutrition. Furthermore the study provides an excellent example of the feasibility and value of the stepped wedge trial design in evaluating pragmatic public health intervention programmes.

How active are rural children in Australian physical education

Physical education lessons offer a venue for children to accrue valuable and health-conferring time being physically active. The first Australian direct observational data are presented on activity of year 3 and 4 children during physical education. Analysis accounts for the nested nature of the data through multi level logistic regression using 13,080 records within 231 lessons within 18 randomly selected schools. Activity was analysed in relation to lesson context (focus of lesson), child gender, school year of child, teacher gender, lesson duration and start time. Children spent 36.7% of a lesson in moderate to vigorous and 12.9% in vigorous activity. Most of the lesson was spent in the context of management/instruction (37.4%), followed by games (25.0%), skill (21.4%), and fitness (14.7%). The highest level of moderate to vigorous activity was observed in the fitness lesson context (61.9%), followed by skill (46.4%), games (42.6%) and management/instruction (17.1%). Moderate to vigorous activity was significantly higher for boys than girls. There was no significant difference in moderate to vigorous activity in lessons led by male or female teachers. However vigorous activity was significantly higher for female led lessons. Children participated in less physical activity during physical education lessons timetabled in the afternoon, compared to physical education lessons time-tabled in the morning. Physical activity levels were not related to lesson duration. Physical education lessons can potentially be more active. However improvement rests on school capacity and may require a health promoting schools approach to implement curricular policy.

Investigation into the skill levels achieved by mathematics students in the V.C.E. and the H.S.C. mathematics courses

This study examines whether recent changes to the mathematics courses offered in the final year of secondary school (Year 12) in the state of Victoria, Australia have affected the learning outcomes of students in terms of then: skill levels in algebra, calculus and problem solving; and in terms of their preparation for a tertiary mathematics unit. The impact of these changes on the transition from secondary to tertiary mathematics is also considered. A comparison is made between students who attempted a first year mathematics unit at the University of Melbourne (U. of M.) having completed the new V.C.E. (Victorian Certificate of Education) mathematics courses and mathematics courses from the previous H.S.C. (Higher School Certificate) system. The comparison involves the use of tests administered upon entrance to a tertiary mathematics unit at the U. of M., and questionnaires. In 1991, V.C.E, students and H.S.C. students attempted the same mathematics test at the U. of M. and their results were compared. In 1992, the tests were attempted by V.C.E. students only. To compare new V.C.E. students and H.S.C. students, questions on the 1991 test were matched with similar questions on the 1992 tests and a panel of experts determined what the H.S.C. students who attempted the 1991 test would have been expected to average on these matched questions on the 1992 tests had they attempted them. These expected average scores were then compared with the actual scores of the new V.C.E. students. The scores of the groups were scaled when necessary. Questionnaires were administered to 1991 U. of M, mathematics students who were part of the V.C.E. pilot group in 1990, secondary mathematics educators, tertiary mathematics educators, and 1991 V.C.E. (1992 U. of M.) students. The mathematical misconceptions exhibited by new V.C.E. students are discussed and their frequencies stated. The research indicates that the new V.C.E. mathematics courses have provided the V.C.E. mathematics students in this study with significantly lower skill levels and a significantly poorer preparation for a tertiary mathematics unit than those which were previously provided by the H.S.C. mathematics courses.

Towards an integration of theories of achievement motivation

This thesis investigated children's school achievement in terms of an integration of three theories of achievement motivation. The three theoretical outlooks were expectancy-value theory (EVT), implicit theories of intelligence (ITI), and flow theory (FT). The first of two studies was an exploratory investigation of the effectiveness of each theory independently and combined to predict children's achievement in four school subjects. The subject areas were maths, reading, instrumental music and sport. Participants were 84 children (40 females and 44 males) aged 9 to 10 years, one of each child's parents, and school teachers of each child in the four subject areas. All data were collected through questionnaires based on the three models. The results indicated that EVT and FT but not ITI accounted for a significant amount of the variance in children's achievement, including effects for subject area and gender. A second confirmatory study tested EVT, FT and an integrated model for the prediction of achievement in maths, reading and instrumental music. The participants were a further 141 children (74 females and 67 males) aged 10 to 11 years, and a parent and teachers of each child. Data collection using questionnaires occurred early in the school year (Timel) and approximately five months later (Time2). For EVT, children and parents’ competence beliefs were significant predictors of children's achievement in each subject area. Females tended to believe themselves more competent at reading and instrumental music and also valued these subjects more highly than boys. Modeling results for flow theory indicated that children's emotional responses to classes (happiness and confusion) were significant predictors of achievement, the type of emotion varying between subject areas and time periods. Females generally had a more positive emotional reaction to reading and instrumental music classes than males did. The integrated model results indicated significant relationships between EVT and flow theories for each subject area, with EVT explaining most achievement variance in the integrated model. Children's and parents’ competence beliefs were the main predictors of achievement at Timel and 2, Subject area and gender differences were found which provide direction for future research. Anecdotal reports of parents and teachers often attest to individual differences in children's involvement in various school domains. Even among children of apparently similar intelligence, it is not uncommon to find one who likes nothing better than to work on a mathematics problem while another much prefers to read a novel or play a musical instrument Some children appear to achieve good results for most of the activities in which they are engaged while others achieve in a less consistent manner, sometimes particularly excelling in one activity. Some children respond to failure experiences with a determination to improve their performance in the future while others react with resignation and acceptance of their low ability. Some children appear to become totally absorbed in the activity of playing sport while others cannot wait for the game to end. The primary research objective guiding the current thesis is how children's thoughts and feelings about school subjects differ and are related to their school achievement. A perusal of the achievement motivation literature indicates several possible models and concepts that can be applied to explain individual differences in children's school achievement. Concepts such as academic self-concept, multiple intelligences, intrinsic and extrinsic motivation, self-beliefs, competence beliefs, subjective task values, mastery and performance goals, ‘Flow’ experiences and social motivation are just some of the constructs used to explain children's achievement motivation, both within and between various activity domains. These constructs are proposed by researchers from different theoretical perspectives to achievement motivation. Although there is much literature relevant to each perspective, there is little research indicating how the various perspectives may relate to each other. The current thesis will begin by reviewing three currently popular theoretical orientations cited in achievement motivation research: subjective beliefs and values; implicit theories of intelligence, and flow experience and family complexity. Following this review, a framework will be proposed for testing the determinants of children's school achievement, both within each of the three theoretical perspectives and also in combination.

Raising 'standards' in schools : considerations in the first stage of an improvement intervention

This article discusses the initial phase of a government-funded intervention to raise school achievement in a cluster of schools with below average standardised test results. Five schools - four primary schools and one secondary school - in the far outer reaches of Melbourne achieved lower standardised test scores in literacy and numeracy than the state average. Two departmental strategies were in place before my involvement the appointment of a coaching teacher in each school, and funding for a four day intensive residential professional learning workshop for these coaching teachers, to be held at the beginning of the 2009 school year. lt was at this stage that I became involved in what was planned to be an ongoing research program to record, monitor and evaluate the success of the intervention.

Building the (mathematical) future.

Here are some questions to ponder during the school year, and other moments. Personal reflection and professional critical analysis are crucial components of an effective teacher's life.

As if they could be otherwise...finding spaces for creativity in the enacted curriculum

This chapter inquires into four very different Australian middle-school classrooms where teachers are innovating their practices and developing new approaches to aspects of English curriculum. These classrooms from diverse settings (one middle-class urban, one elite private inner urban, one regional disadvantaged, one middle-class regional) have all taken imaginative leaps and reworked their curricula to put the students’ needs at the centre. At one school, Year 8 students design, make and play their own computer games, at another Year 6 students script, design, craft and shoot their own claymation film; at another, Year 9 students use videogames as texts in their literature studies; and at another, a group of Year 6 students work with a theatre company and their teachers to rework Shakespeare into a contemporary, accessible, enjoyable performance. The chapter considers how in each case these different approaches engage and extend the students in meaningful and relevant ways. The chapter includes a mix of teacher and student interview data, principal data and teacher writing. The chapter investigates how each of these projects worked to achieve its aims and discusses how the single national curriculum might be re-envisioned in local contexts.

Science students' perceptions of engaging pedagogy

During their years of schooling, students develop perceptions about learning and teaching, including the ways in which teachers impact on their learning experiences. This paper presents student perceptions of teacher pedagogy as interpreted from a study focusing on students' experience of Year 7 science. A single science class of 11 to 12 year old students and their teacher were monitored for the whole school year, employing participant observation, and interviews with focus groups of students, their teacher and other key members of the school. Analysis focused on how students perceived the role of the teacher's pedagogy in constructing a learning environment that they considered conducive to engagement with science learning. Two areas of the teacher's pedagogy are explored from the student perspective of how these affect their learning: instructional pedagogy and relational pedagogy. Instructional pedagogy captures the way the instructional dialogue developed by the teacher drew the students into the learning process and enabled them to “understand” science. How the teacher developed a relationship with the students is captured as relational pedagogy, where students said that they learned better when teachers were passionate in their approach to teaching, provided a supportive learning environment and made them feel comfortable. The ways in which the findings support the direction for the middle years and science education are considered.

Assessing the reading and writing of EAL/D students: issues and implications

This paper reports on the preliminary findings of a study on literacy strategies for learners in established English as an Additional Language (EAL) classes in Years 7-10 in three Victorian secondary schools. The paper draws on baseline reading and writing assessment results (N=45). 

Triple G girls get going in tennis : resource manual

Physical activity is ranked second in importance only to tobacco control in health promotion and disease prevention in Australia. Individuals can be active in many ways every day, including –walking to and/or from school, work and other places of interest; participating in sports clubs; going to the YMCA or community leisure centre where you can be active through gyms, group fitness classes or in the swimming pool; visiting local parks and walking trails, and even at home and in the backyard. You can always find ways to be active in the community.

Promoting physical activity to young people is important for developing healthy lifestyles now and maintaining them for the future. A physically active lifestyle can be of benefit to physical, mental and social health. Despite these benefits, adolescent girls and young women are considerably less active than their male counterparts, and sport participation decreases dramatically among girls during their secondary school years. Many physical education teachers have also expressed concern about girls minimising their participation in school physical education. Consequently, it is timely that a project such as Triple G ‘Girls Get Going in Tennis, in Football, and at the YMCA’ should be developed and implemented in an effort to arrest the decline in girls’ participation in sport, physical activity and physical education.

The Triple G program aims to develop, implement and evaluate a program to promote participation in physical activity by girls in rural and regional schools and communities. The impact of the Triple G program on the mental and physical wellbeing of the girls will also be evaluated. The program specifically aims to create school and community linkages through the introduction of tennis coaches, football coaches, and YMCA instructors into the physical education class to team teach with physical education staff during the 2011 school year. As part of the school-based program, Year 7 – 9 girls will participate in a YMCA unit and one of tennis or football during their physical education classes (6 sessions x 100mins each). Each unit is then followed by an eight week afterschool program at the local tennis or football club, or YMCA centre.
