Best practice in peer-led curriculum content : informing an interactive program to improve passenger safety among high school seniors

Despite ongoing improvements in behaviour change strategies, licensing models and road law enforcement measures young drivers remain significantly over-represented in fatal and non-fatal road related crashes. This paper focuses on the safety of those approaching driving age and identifies both high priority road safety messages and relevant peer-led strategies to guide the development school programs. It summarises the review in a program logic model built around the messages and identified curriculum elements, as they may be best operationalised within the licensing and school contexts in Victoria. This paper summarises a review of common deliberate risk-taking and non-deliberate unsafe driving behaviours among novice drivers, highlighting risks associated with speeding, driving while fatigued, driving while impaired and carrying passengers. Common beliefs of young people that predict risky driving were reviewed, particularly with consideration of those beliefs that can be operationalised in a behaviour change school program. Key components of adolescent risk behaviour change programs were also reviewed, which identified a number of strategies for incorporation in a school based behaviour change program, including: a well-structured theoretical design and delivery, thoughtfully considered peer-selected processes, adequate training and supervision of peer facilitators, a process for monitoring and sustainability, and interactive delivery and participant discussions. The research base is then summarised in a program logic model with further discussion about the quality of the current state of knowledge of evaluation of behaviour change programs and the need for considerable development in program evaluation.

A Randomized Controlled Trial Evaluation of Time to Read, a Volunteer Tutoring Program for 8-9 Year Olds

Tutoring is commonly employed to prevent early reading failure, and evidence suggests that it can have a positive effect. This article presents findings from a large-scale (n = 734) randomized controlled trial evaluation of the effect of Time to Read—a volunteer tutoring program aimed at children aged 8 to 9 years—on reading comprehension, self-esteem, locus of control, enjoyment of learning, and future aspirations. The study found that the program had only a relatively small effect on children’s aspirations (effect size +0.17, 95% confidence interval [0.015, 0.328]) and no other outcomes. It is suggested that this lack of evidence found may be due to misspecification of the program logic model and outcomes identified and program-related factors, particularly the low dosage of the program.

Curriculum design and higher order skills : challenging assumptions

This paper is based on an Australian Learning & Teaching Council (ALTC) funded evaluation in 13 universities across Australia and New Zealand of the use of Engineers Without Borders (EWB) projects in first-year engineering courses. All of the partner institutions have implemented this innovation differently and comparison of these implementations affords us the opportunity to assemble "a body of carefully gathered data that provides evidence of which approaches work for which students in which learning environments". This study used a mixed-methods data collection approach and a realist analysis. Data was collected by program logic analysis with course co-ordinators, observation of classes, focus groups with students, exit survey of students and interviews with staff as well as scrutiny of relevant course and curriculum documents. Course designers and co-ordinators gave us a range of reasons for using the projects, most of which alluded to their presumed capacity to deliver experience in and learning of higher order thinking skills in areas such as sustainability, ethics, teamwork and communication. For some students, however, the nature of the projects decreased their interest in issues such as ethical development, sustainability and how to work in teams. We also found that the projects provoked different responses from students depending on the nature of the courses in which they were embedded (general introduction, design, communication, or problem-solving courses) and their mode of delivery (lecture, workshop or online).

Youth programs in remote Indigenous communities: Context matters

A diversity of programs oriented to young people seek to develop their capacities and their connection to the communities in which they live. Some focus on ameliorating a particular issue or ‘deficit’ whilst others, such as sporting, recreation and youth groups are more grounded in the community. This article reports a qualitative study undertaken in three remote Indigenous communities in Central Australia. Sixty interviews were conducted with a range of stakeholders involved in a diversity of youth programs. A range of critical challenges for and characteristics of remote Indigenous youth programs are identified if such programs are to be ‘fit for context’. ‘Youth centred-context specific’ provides a positive frame for the delivery of youth programs in remote Central Australia, encouraging an explicit focus on program logic; program content and processes; and relational, temporal, and, spatial aspects of the practice context. These provide lenses with which youth program planning and delivery may be enhanced in remote communities. Culturally safe service planning and delivery suggests locally determined processes for decision-making and community ownership. In some cases, this may mean a community preference for all ages to access the service to engage in culturally relevant activities. Where activities are targeted at young people, yet open to and inclusive of all ages, they provide a medium for cross-generational interaction that requires a high degree of flexibility on the part of staff and funding programs. Although the findings are focused in Central Australia, they may be relevant to similar contexts elsewhere.

Abitbol : un langage sur mesure pour la métaprogrammation

Ce mémoire a pour thèse que les fonctions devraient être transparentes lors de la phase de métaprogrammation. En effet, la métaprogrammation se veut une possibilité pour le programmeur d’étendre le compilateur. Or, dans un style de programmation fonctionnelle, la logique du programme se retrouve dans les définitions des diverses fonctions le composant. Puisque les fonctions sont généralement opaques, l’impossibilité d’accéder à cette logique limite les applications possibles de la phase de métaprogrammation. Nous allons illustrer les avantages que procurent les fonctions transparentes pour la métaprogrammation. Nous donnerons notamment l’exemple du calcul symbolique et un exemple de nouvelles optimisations désormais possibles. Nous illustrerons également que la transparence des fonctions permet de faire le pont entre les datatypes du programme et les fonctions. Nous allons également étudier ce qu'implique la présence de fonctions transparentes au sein d'un langage. Nous nous concentrerons sur les aspects reliés à l'implantation de ces dernières, aux performances et à la facilité d'utilisation. Nous illustrerons nos propos avec le langage Abitbol, un langage créé sur mesure pour la métaprogrammation.

Probabilistic reasoning with a bayesian DNA device based on strand displacement

We present a computing model based on the DNA strand displacement technique which performs Bayesian inference. The model will take single stranded DNA as input data, representing the presence or absence of a specific molecular signal (evidence). The program logic encodes the prior probability of a disease and the conditional probability of a signal given the disease playing with a set of different DNA complexes and their ratios. When the input and program molecules interact, they release a different pair of single stranded DNA species whose relative proportion represents the application of Bayes? Law: the conditional probability of the disease given the signal. The models presented in this paper can empower the application of probabilistic reasoning in genetic diagnosis in vitro.

Probabilistic reasoning with an enzyme-driven DNA device

We present a biomolecular probabilistic model driven by the action of a DNA toolbox made of a set of DNA templates and enzymes that is able to perform Bayesian inference. The model will take single-stranded DNA as input data, representing the presence or absence of a specific molecular signal (the evidence). The program logic uses different DNA templates and their relative concentration ratios to encode the prior probability of a disease and the conditional probability of a signal given the disease. When the input and program molecules interact, an enzyme-driven cascade of reactions (DNA polymerase extension, nicking and degradation) is triggered, producing a different pair of single-stranded DNA species. Once the system reaches equilibrium, the ratio between the output species will represent the application of Bayes? law: the conditional probability of the disease given the signal. In other words, a qualitative diagnosis plus a quantitative degree of belief in that diagno- sis. Thanks to the inherent amplification capability of this DNA toolbox, the resulting system will be able to to scale up (with longer cascades and thus more input signals) a Bayesian biosensor that we designed previously.
