Building Conceptual Knowledge Of Fraction Operations Among Pre-Service Teachers: Effect Of A Representation-Based Teaching Approach Within A Teacher Education Program, Elise J. Thurtell, Patricia A. Forrester, Mohan Chinnappan

Faculty of Social Sciences - Papers (Archive)

A deep understanding of fraction concepts and operations is necessary if pre-service teachers (PSTs) are to present the concepts in multiple forms to learners. Such an understanding needs to be grounded in rich conceptual knowledge. In the present study, we explore the development of this understanding by supporting a cohort of 103 PSTs, who had previously demonstrated poor conceptual understanding of fraction concepts and operations, with a Representational Reasoning in Teaching and Learning (RRTL) approach aimed at strengthening their conceptual knowledge. A comparison of pre- and post-test results indicated that participants showed a significant improvement in shifting the balance of …

Objectives We examined the potential influence of both sample selection effects and Hawthorne effects in the behavioural HIV Prevention Trial Network 068 study, designed to examine whether cash transfers conditional on school attendance reduce HIV acquisition in young South African women. We explored whether school enrolment among study participants differed from the underlying population, and whether differences existed at baseline (sample selection effect) or arose during study participation (Hawthorne effect). Methods We constructed a cohort of 3889 young women aged 11-20 years using data from the Agincourt Health and socio-Demographic Surveillance System. We compared school enrolment in 2011 (trial start) …

Background:

Attending school may have a strong preventative association with sexually transmitted infections among young women, but the mechanism for this relationship is unknown. One hypothesis is that students who attend school practice safer sex with fewer partners, establishing safer sexual networks that make them less exposed to infection.

Setting:

We used longitudinal data from a randomized controlled trial of young women aged 13–20 years in the Bushbuckridge district, South Africa, to determine whether the percentage of school days attended, school dropout, and grade repetition are associated with having a partner 5 or more years older (age–disparate) and with the …

The Delaying Effect Of Stigma On Mental Health Help-Seeking In Sri Lanka, Sunera M. Fernando, Frank P. Deane, Hamish J. Mcleod

Faculty of Social Sciences - Papers (Archive)

Background: Mental health stigma has been associated with delays in seeking treatment. Aims: To describe perceived stigma experienced by patients and carers in Sri Lanka and to determine the effects of stigma on help-seeking delay. Methods: Survey of outpatients and family carers (n = 118 dyads) attending two psychiatric hospitals in Sri Lanka, using the Disclosure and Discrimination subscales of the Stigma Scale. Results: Stigma was positively related to help-seeking delay for carers but not patients. Public stigma experienced by carers accounted for 23% of the variance in help-seeking delay. Conclusion: Reducing stigma may reduce help-seeking delays during the course …

Sequential Processing And The Matching-Stimulus Interval Effect In Erp Components: An Exploration Of The Mechanism Using Multiple Regression, Genevieve Z. Steiner, Robert J. Barry, Craig J. Gonsalvez

Faculty of Social Sciences - Papers (Archive)

In oddball tasks, increasing the time between stimuli within a particular condition (target-to-target interval, TTI; nontarget-to-nontarget interval, NNI) systematically enhances N1, P2, and P300 event-related potential (ERP) component amplitudes. This study examined the mechanism underpinning these effects in ERP components recorded from 28 adults who completed a conventional three-tone oddball task. Bivariate correlations, partial correlations and multiple regression explored component changes due to preceding ERP component amplitudes and intervals found within the stimulus series, rather than constraining the task with experimentally constructed intervals, which has been adequately explored in prior studies. Multiple regression showed that for targets, N1 and TTI …

Recovering Knowledge For Science Education Research: Exploring The "Icarus Effect" In Student Work, Helen Georgiou, Karl A. Maton, Manjula Sharma

Faculty of Social Sciences - Papers (Archive)

Science education research has built a strong body of work on students' understandings but largely overlooked the nature of science knowledge itself. Legitimation Code Theory (LCT), a rapidly growing approach to education, offers a way of analyzing the organizing principles of knowledge practices and their effects on science education. This article focuses on one specific concept from LCT-semantic gravity-that conceptualizes differences in context dependence. The article uses this concept to qualitatively analyze tertiary student responses to a thermal physics question. One result, that legitimate answers must reside within a specific range of context dependence, illustrates how a focus on the …

Recent studies suggest that stress can amplify the harm of air pollution. We examined whether experience of racism and exposure to particulate matter with an aerodynamic diameter of less than 2.5 µm and 10 µm (PM_2.5 and PM₁₀) had a synergistic influence on ethnic differences in asthma and lung function across adolescence. Analyses using multilevel models showed lower forced expiratory volume (FEV₁), forced vital capacity (FVC) and lower rates of asthma among some ethnic minorities compared to Whites, but higher exposure to PM_2.5, PM₁₀ and racism. Racism appeared to amplify the relationship …

Do Social Interactions Explain Ethnic Differences In Psychological Distress And The Protective Effect Of Local Ethnic Density? A Cross-Sectional Study Of 226 487 Adults In Australia, Xiaoqi Feng, Thomas Astell-Burt, Gregory Kolt

Faculty of Social Sciences - Papers (Archive)

Background A frequently proposed, but under-researched hypothesis is that ethnic density benefits mental health through increasing social interactions. We examined this hypothesis in 226 487 adults from 19 ethnic groups aged 45 years and older in Australia. Methods Multilevel logit regression was used to measure the association between ethnicity, social interactions, own-group ethnic density and scores of 22+ on the Kessler scale of psychological distress. Self-reported ancestry was used as a proxy for ethnicity. Measures of social interactions included a number of times in the past week were (i) spent with friends or family participants did not live with; (ii) …

Holistic coding for faces is shown in several illusions that demonstrate integration of the percept across the entire face. The illusions occur upright but, crucially, not inverted. Converting the illusions into experimental tasks that measure their strength - and thus index degree of holistic coding - is often considered straightforward yet in fact relies on a hidden assumption, namely that there is no contribution to the experimental measure from secondary cognitive factors. For the composite effect, a relevant secondary factor is size of the "spotlight" of visuospatial attention.The composite task assumes this spotlight can be easily restricted to the target …

Background One of the major challenges associated with our ageing population is the increasing incidence of age-associated cognitive decline, which has significant implications for an individual's ability to lead a productive and fulfilling life. In pure economic terms the costs of ageing reflects decreased productivity and engagement with the workforce. The maintenance of brain health underpinning intact cognition is a key factor to maintaining a positive, engaged, and productive lifestyle. In light of this, the role of diet, including supplementation with nutritional and even pharmacological interventions capable of ameliorating the neurocognitive changes that occur with age constitute vital areas of …

Conditional Recall And The Frequency Effect In The Serial Recall Task: An Examination Of Item-To-Item Associativity, Leonie M. Miller, Steven J. Roodenrys

Faculty of Social Sciences - Papers (Archive)

The frequency effect in short-term serial recall is influenced by the composition of lists. In pure lists, a robust advantage in the recall of high-frequency (HF) words is observed, yet in alternating mixed lists, HF and low-frequency (LF) words are recalled equally well. It has been argued that the preexisting associations between all list items determine a single, global level of supportive activation that assists item recall. Preexisting associations between items are assumed to be a function of language co-occurrence; HF-HF associations are high, LF-LF associations are low, and mixed associations are intermediate in activation strength. This account, however, is …

Differential Effect Of Contrast Polarity Reversals In Closed Squares And Open L-Junctions, Mark M. Schira, Branka Spehar

Faculty of Social Sciences - Papers (Archive)

Scene segmentation depends on interaction between geometrical and photometric factors. It has been shown that reversals in contrast polarity at points of highest orientation discontinuity along closed contours significantly impair shape discrimination performance, while changes in contrast polarity at straight(er) contour segments do not have such deleterious effects (Spehar, 2002). Here we employ (semi) high resolution fMRI (1.5 mm x 1.5 mm x 1.5 mm) to investigate the neuronal substrate underlying these perception effects. Stimuli consisted of simple elements (a) squares with contrast reversals along straight segments; (b) squares with contrast reversals in the corner (highest orientation discontinuity); (c) L-Junctions …
