School-based early intervention and later child maltreatment in the Chicago Longitudinal Study

Investigated were the effects of participation in the Title I Child-Parent Centers (CPC) on substantiated reports of child maltreatment for 1,408 children (93% of whom are African American) in the Chicago Longitudinal Study. The CPCs provide child education and family support services in high-poverty areas. After adjusting for preprogram maltreatment and background factors, 913 preschool participants had significantly lower rates of court petitions of maltreatment by age 17 than 495 children of the same age who participated in alternative kindergarten interventions (5.0% vs. 10.5%, a 52% reduction). Participation for 4 to 6 years was significantly associated with lower rates of maltreatment (3.6% vs. 6.9%, a 48% reduction). Findings based on child protective service records (as well as combined protective service and court records) were similar. Preschool length, family risk, and school poverty were associated with lower rates of maltreatment. Parental involvement in school and school mobility were significant mediators of intervention effects.     

Infants' perception of object trajectories

Filling in the gaps in what humans see is a fundamental perceptual skill, but little is known about the developmental origins of occlusion perception. Three experiments were conducted with infants between 2 and 6 months of age to investigate perception of the continuity of an object trajectory that was briefly occluded. The pattern of results across experiments provided little evidence of veridical responses to trajectory occlusion in the youngest infants, but by 6 months, perceptual completion was more robust. Four-month-olds' responses indicated that they perceived continuity under a short duration of occlusion, but when the object was out of sight for a longer interval, they appeared to perceive the trajectory as discontinuous. These results suggest that perceptual completion of a simple object trajectory (and, by logical necessity, veridical object perception) is not functional at birth but emerges across the first several months after onset of visual experience.     

Parallel literacy classes and hidden strengths: learning to read in English,Urdu and classical Arabic

The aim of this article is to explore young bilingual children’s early literacy experiences in three different languages, English, Urdu and classical Arabic, and in three strikingly different types of classes in England. It draws on a larger ethnographic study that sets out to discover what kinds of advantages or additional strengths bilingual children might bring from their community literacy practices and from their experiences of learning to read in two or more languages simultaneously into their English literacy lessons. The main focus of the article is on one bilingual boy, Ikram, of Pakistani background, who at the beginning of the study was 5 years old. The participant observations in these three different types of classes and audio and video tapes of some these lessons show that at the age of 7 Ikram has begun to read in three languages. I argue that in doing so he is developing additional strengths that are generally overlooked. These new types of literacy strengths derive from the fact he is learning to read simultaneously in three languages. Yet they remain hidden within his English lessons.     

Popularising science through television

Conclusion Currently the 26 films in the Science Territory series have been shown to audiences who watch Channel 8 commercial television in the vicinity of Darwin. They are still being shown to audienc who watch Imparja Television. There are no plans at the moment to shown Science Territory for any extra time on either Channel 8 or Imparja, once the Imparja programmes are completes. There are plans however to develop materials to complement the programmes, which could be used in schools and there are also plans to repeat the success of Science Territory and to expand it on a national basis to a series of programmes to be called “Science Oz”. This research note has described of the Scienc Territory project which has attempted to improve students' and parents' attitudes to science. It has alo attempted to explain how the issue of determining the effectiveness of the project has been addressed. Overall, Science Territory proved to be an interesting, exciting, successful and whorthwhile venture, particularly for the small scientific community of the Northern Territory. It also appears to be unique both in Australia and worldwide. There are therefore lessons that science educators can learn from this about new ways of improving students' attitudes to science.

On document relevance and lexical cohesion between query terms

Lexical cohesion is a property of text, achieved through lexical-semantic relations between words in text. Most information retrieval systems make use of lexical relations in text only to a limited extent. In this paper we empirically investigate whether the degree of lexical cohesion between the contexts of query terms’ occurrences in a document is related to its relevance to the query. Lexical cohesion between distinct query terms in a document is estimated on the basis of the lexical-semantic relations (repetition, synonymy, hyponymy and sibling) that exist between there collocates – words that co-occur with them in the same windows of text. Experiments suggest significant differences between the lexical cohesion in relevant and non-relevant document sets exist. A document ranking method based on lexical cohesion shows some performance improvements.     

The humanities in the primary school – where are we and in which direction should we be heading? A perspective from Scotland

ABSTRACT

In Scotland, although there is no agreed definition of what constitutes the humanities, they have their locus principally within two of eight curricular areas in Curriculum for Excellence (CfE): Social Studies (SS) and Religious and Moral Education (RME). Both SS and RME are contexts for learning where broad principles apply in relation to curricular coverage. These principles are formalised in Experiences and Outcomes for each of these curricular areas which provide broad guidance around topic areas for study while allowing for the use of local contexts for learning and flexibility in pedagogy. Key opportunities in SS include: exciting and engaging learners, enabling personalisation and choice and equipping learners with a range of skills. In RME, opportunities include helping learners to: understand themselves and others; draw upon religious and other beliefs in forming their own views and engaging in positive social change. Key challenges for SS include: ensuring breadth and depth of coverage; reaching agreed standards across the educational community; responding to the requirement for an increased focus on literacy and numeracy. In RME challenges include: ensuring that national expectations are met; ensuring breadth and depth in learning; the nature and role of assessment; practitioner and parental conceptualisations of the curricular area.     

On rank-based effectiveness measures and optimization

Many current retrieval models and scoring functions contain free parameters which need to be set—ideally, optimized. The process of optimization normally involves some training corpus of the usual document-query-relevance judgement type, and some choice of measure that is to be optimized. The paper proposes a way to think about the process of exploring the space of parameter values, and how moving around in this space might be expected to affect different measures. One result, concerning local optima, is demonstrated for a range of rank-based evaluation measures.

Beyond Average: Contemporary statistical techniques for analysing student evaluations of teaching

Student evaluations of teaching (SETs) have been used to evaluate higher education teaching performance for decades. Reporting SET results often involves the extraction of an average for some set of course metrics, which facilitates the comparison of teaching teams across different organisational units. Here, we draw attention to ongoing problems with the naive application of this approach. Firstly, a specific average value may arise from data that demonstrates very different patterns of student satisfaction. Furthermore, the use of distance measures (e.g. an average) for ordinal data can be contested, and finally, issues of multiplicity increasingly plague approaches using hypothesis testing. It is time to advance the methodology of the field. We demonstrate how multinomial distributions and hierarchical Bayesian methods can be used to contextualise the SET scores of a course to different organisational units and student cohorts, and then show how this approach can be used to extract sensible information about how a distribution is changing.     

In pursuit of quality: early childhood qualifications and training policy

This paper aims to critique policy discourses around the pursuit of quality in early years education. Taking England as a focal point, it problematizes the use of the term ‘quality’ and attempts to standardise its meaning; highlighting the disconnect that exists between policy and practice. The paper combines discourse analysis of a small number of key government documents with a series of interviews with early years stakeholders in order to identify issues that will have resonance and can inform a much needed continuation of debates about what quality might mean. Over the course of the research it became apparent that there was considerable disquiet amongst early years practitioners with regards the current qualifications and training landscape, particularly with regards to what many viewed as ideologically-driven policy-making, not informed by proper dialogue with the sector.
