“Project Screen” — A Follow‐up Study of a Pre‐school Screening Battery

This study examines a pre‐school screening survey battery with an aim to validate it in terms of predicting school performance. Subjects participating in the screening were tested at the end of their first year at school. Analysis of the data, using a canonical correlation procedure, suggested elimination of a number of test items ‐‐ age, sex, age of walking, socio‐economic rating, Draw‐a‐Man Test, balance and posture, body image, perceptual motor match, height and weight. Measures of general ability, visual discrimination, visual reception, general development, receptive language, language concepts and positional concepts were the best predictors of school performance.     

The rewarding effects of number and surface area of food in rats

Visual cues have an important role in food preference for both rats and humans. Here, we aim to isolate the effects of numerosity, density, and surface area on food preference and running speed in rats, by using a forced-choice maze paradigm. In Experiment 1, rats preferred and ran faster for a group of multiple smaller pellets rather than a single large pellet, corroborating previous research (Capaldi, Miller, & Alptekin Journal of Experimental Psychology: Animal Behavior Processes, 15(1), 75–80, 1989). Further experiments tested the prevailing hypothesis that multiple food pieces are more reinforcing because they occupy a larger surface area. Experiment 2 controlled for numerosity by utilizing a continuous food: mashed potatoes flattened to cover a larger surface area or rounded into a ball. The rats preferred and ran faster for the flattened potatoes, suggesting surface area plays a role in quantity estimations. Finally, in Experiment 3, rats displayed no preference or difference in running speed between a group of scattered and clustered pellets when number of pellets were kept constant. Taken together, these results suggest that density has an important role in food perception—that is, the rewarding effect of higher numerosity or larger surface area is removed when the food does not fill out the entire space. Alternative explanations and implications for human diet are discussed.     

ENGAGING SCIENCE: PRE-SERVICE PRIMARY SCHOOL TEACHERS�� NOTIONS OF ENGAGING SCIENCE LESSONS

If children are engaged in science lessons, their learning is likely to be better and, in the long term, careers in science and technology will remain open. Given that attitudes can develop early and be difficult to change, it is important for teachers of younger children to know how to foster engagement in science. This study identified what a cohort of 79 pre-service teachers in England considered to be engaging elementary science lessons and compared their notions with teacher behaviours known to be conducive to engagement. First, all brought beliefs about how to engage children in science lessons to their training. They tended to favour children’s hands-on activity as an effective means of fostering attentive participation in learning, although many had additional ideas. Nevertheless, the means and ends of their ‘pedagogies of engagement’ tended to be simple and narrow. Trainers need to ensure that notions of engagement are wide enough to cope with a variety of teaching situations, as when hands-on experience is not feasible, effective or appropriate. At the same time, teachers will need to recognise that one approach may not suit all learners. Without this, there is the risk that they will lack the skills to engage children in science. Nevertheless, these beliefs could offer a useful starting point for trainers who wish to widen pre-service teachers’ conceptions of engagement and increase their repertoire of teaching behaviours.     

A Dual Identity Approach for Conceptualizing and Measuring Children's Gender Identity

The goal was to test a new dual identity perspective on gender identity by asking children (n = 467) in three grades (M_age = 5.7, 7.6, 9.5) to consider the relation of the self to both boys and girls. This change shifted the conceptualization of gender identity from one to two dimensions, provided insights into the meaning and measurement of gender identity, and allowed for revisiting ideas about the roles of gender identity in adjustment. Using a graphical measure to allow assessment of identity in young children and cluster analyses to determine types of identity, it was found that individual and developmental differences in how similar children feel to both genders, and these variations matter for many important personal and social outcomes.     

The role of further government intervention in Australian international education

Trade in Australian education services has expanded rapidly over recent years. The sector is the third largest exporter of Australian services. In 2001–2002, exports of education were about $A 4.2 billion. Government assistance to the sector includes export market development, regulation of education standards, and funding education activities; university research and development, for example. This paper examines the case for further government intervention in the export of education, and the appropriate forms of assistance if further government intervention is justified. The paper predominately focuses on assisting higher education exports because this activity dominates education exports.     

A large-scale test of the relationship between procrastination and performance using learning analytics

Abstract

Many studies have found a relationship between students’ self-reported procrastination and their grades. Few studies have used learning analytic data as a behavioural measure of procrastination in order to predict performance, and there is no systematic research on how this relationship may differ across assessments or disciplines. In this study we analyse nine years’ worth of institutional electronic submission records, a total of 73,608 assignment submissions, to examine the relationship between submission time and grades across assignments, students, courses, and disciplines in higher education. A significant negative relationship was found overall, with students who submitted closer to the deadline obtaining lower grades, however the size of the relationship was negligible, accounting for less than 1% of the variance in grades. The relationship varied significantly depending on student, assignment, course and discipline.
