The impact of curriculum change on health sciences first year students’ approaches to learning

This study aimed to use a learning inventory (the Approaches and Study Skills Inventory for Students, ASSIST) to measure the impact of a curriculum change on students’ approaches to learning in two large courses in a health sciences first year programme. The two new Human Body Systems (HUBS) courses were designed to encourage students to take a deep approach to learning. ASSIST was completed by 599 students enrolled in a biology class in 2006 that was part of the old curriculum, and by 705 students at the beginning and end of the new HUBS courses in 2007. Changes in students’ approaches to learning over time were examined. The ASSIST scores for both HUBS courses reflected the dominance of a surface approach, followed by a strategic and then a deep approach. However, by the end of the year, students were taking a deep and strategic approach to their studies to a greater extent, and a surface approach to a lesser extent. Moreover, students enrolled in the new course adopted a deep approach to their studies to a significantly greater degree than those studying the old curriculum. Despite the predominance of a surface approach, the results suggest that it is possible to bring about small but significant positive changes in students’ learning behaviour in a very large class through curriculum change. The proportion of students preferring a surface approach, and results showing that high performance on the final exam was significantly correlated with a surface approach, probably reflected contextual factors, including assessment, and is the focus of ongoing curriculum development.     

Metastasis and retroactive causality in incentive rhetoric

Our contemporary moment is characterized by the pervasiveness of economics in social life, and the extension of “incentives” into new areas represents this movement’s keystone. Originally a fairly narrow term from neoclassical economic theory, politicians, journalists, and cultural ?gures deploy “incentives” to explain all manner of activity: judicial rulings, gendered wage gaps, and even whether soccer players score penalty kicks. To address this, I elucidate the trope of metastasis – the rhetorical mechanism by which social life is “economized.” Metastasis entails a ?gurative displacement, wherein cause shifts from one place to another. More than simply a spread of narrow economic ideas into culture, incentive rhetoric metastasizes. It displaces alternative explanations onto neoclassical market axioms. Since its proponents insist that incentives are causal mechanisms, I introduce Jacques Lacan’s interpretation of Aristotle’s discourse on causality. Lacan rereads Aristotle’s “?nal cause” from a rhetorical perspective, and forwards the retroactive causality of the symbolic order. Incentive rhetoric exempli?es this concept, in which all outcomes are explained as having been caused by a prior, unseen market force. Incentive rhetorics promise a universal code that unlocks the mysteries of human behavior that reduces all context to discrete individual choices, thereby providing a discursive alibi for economic inequality.     

The effects of dialect awareness instruction on nonmainstream American English speakers

The achievement gaps between poor and more affluent students are persistent and chronic, as many students living in poverty are also members of more isolated communities where dialects such as African American English and Southern Vernacular English are often spoken. Non-mainstream dialect use is associated with weaker literacy achievement. The principal aims of the two experiments described in this paper were to examine whether second through fourth graders, who use home English in contexts where more formal school English is expected, can be taught to dialect shift between home and school English depending on context; and whether this leads to stronger writing and literacy outcomes. The results of two randomized controlled trials with students within classrooms randomly assigned to DAWS (Dialect Awareness, a program to explicitly teach dialect shifting), editing instruction, or a business as usual group revealed (1) that DAWS was more effective in promoting dialect shifting than instruction that did not explicitly contrast home and school English; and (2) that students in both studies who participated in DAWS were significantly more likely to use school English in contexts where it was expected on proximal and distal outcomes including narrative writing, morphosyntactic awareness, and reading comprehension. Implications for theory and practice are discussed.     

Examining the Efficacy of Targeted Component Interventions on Language and Literacy for Third and Fourth Graders Who are at Risk of Comprehension Difficulties

Testing a component model of reading comprehension in a randomized controlled trial, we evaluated the efficacy of 4 interventions that were designed to target components of language and metacognition that predict children’s reading comprehension: vocabulary, listening comprehension, comprehension of literate language, academic knowledge, and comprehension monitoring. Third- and 4th-graders with language skills falling below age expectations participated (N = 645). Overall, the component interventions were only somewhat effective in improving the targeted skills, compared to a business-as-usual control (g ranged from ?.14 to .33), and no main effects were significant after correcting for multiple comparisons. Effects did not generalize to other language skills or to students’ reading comprehension. Moreover, there were Child Characteristic × Treatment interaction effects. For example, the intervention designed to build sensorimotor mental representations was more effective for children with weaker vocabulary skills. Implications for component models of reading and interventions for children at risk of reading comprehension difficulties are discussed.     

Portfolio assessment: direct from the classroom

Portfolios have been regarded as a means of personal self‐expression. This study reports on student real‐life experiences with portfolio assessment. The focus group comprised 150 freshmen (100 females) from a small campus of a tertiary educational institution. For two semesters (approximately 30 weeks), students engaged in numerous activities selected to encourage deep learning and understanding of mathematical concepts. Because students were not involved in the experiment, ecological validity was maximised, and observations may be regarded as fairly authentic and worthy of analysis. Generally, students reported learning much from portfolio assessment and felt an integral part of the assessment process. Portfolio assessment appeared to empower students and provide them with the self‐respect they desired. Future research could compare results from everyday observations with those from experiments.     

Complexity of Secondary Scientific Data Sources and Students’ Argumentative Discourse

This study examined the learning opportunities provided to students through the use of complex geological data supporting scientific inquiry. Through analysis of argumentative discourse in a high school Earth science classroom, uses of US Geological Survey (USGS) data were contrasted with uses of geoscience textbook data. To examine these differences, we conducted a review of frameworks for argumentation analysis, and through adaptation to the research foci of this study, developed a new analytic approach. Applying this approach to student classroom discourse revealed the affordances and constraints of both the complex USGS datasets and the filtered textbook data sources. The challenges of teaching with complex data are presented.     

A validity study of two paper-pencil tests of concrete and formal operations

Two group paper-pencil batteries, the Longeot (consisting of three subtests) and three puzzles (KLR) from Science Teaching and the Development of Reasoning, were administered to 607 students from ninth and tenth grade mathematics and science classes. A subsample of 69 students was then administered three Inhelder tasks (chemicals, rods, and shadows). In general, the expected developmental trends were confirmed, with formal status being most difficult to attain on the Inhelder tasks and easiest to attain on the Longeot. The correlations between the KLR and Inhelder (0.61, p < 0.01) and the Longeot and Inhelder (0.55, p < 0.05) were moderately high. According to the method of Shayer (Note 2), it was found that each of five paper-pencil subtests discriminates at or between the 2B (late concrete) and 3A (early formal) levels while the sixth subtest, the mealworm puzzle, was found to discriminate at the 3A level. This study indicates that either group battery may be useful in identifying transitional subjects. However, if a more stringent criterion of “formal” is needed, a “success” rate of four or five out of the six subtests may be required. Both group batteries are relatively easy to administer and score with a minimum of guidance, although the KLR scoring might need to be simplified for use by the practitioner. Sex differences found on the KLR and the Longeot are suggestive of the potential differential use of these tests by researchers investigating sex differences in achievement or aptitude.     

A comparison of haemolytic responses in fore-foot and rear-foot distance runners

This study examined the haemolytic effects of an interval-based running task in fore-foot and rear-foot striking runners. Nineteen male distance runners (10 fore-foot, 9 rear-foot) completed 8 × 3 min repeats at 90% vVO_2peak on a motorised treadmill. Pre- and post-exercise venous blood samples were analysed for serum haptoglobin to quantify the haemolytic response to running. Vertical ground reaction forces were also captured via a force plate beneath the treadmill belt. Haptoglobin levels were significantly decreased following exercise (P = 0.001) in both groups (but not between groups), suggesting that the running task created a haemolytic stress. The ground reaction force data showed strong effect sizes for a greater peak force (d = 1.20) and impulse (d = 1.37) in fore-foot runners, and a greater rate of force development (d = 2.74) in rear-foot runners. The lack of difference in haptoglobin response between groups may be explained by the trend for fore-foot runners to experience greater peak force and impulse during the stance phase of their running gait, potentially negating any impact of the greater rate of force development occurring from the rear-foot runners’ heel strike. Neither type of runner (fore-foot or rear-foot) appears more susceptible to technique-related foot-strike haemolysis.     

Occupational branding for diversity: managing discursive contradictions

In line with recent efforts to increase the representation of women in the field of computing and information technology (I.T.), the National Center for Women and Information Technology has spearheaded an occupational branding campaign that seeks to encourage more women to enter this field. We use this campaign as a case study to investigate how representations of work in an occupational branding campaign (“official branding discourse”) compare with the ways in which practitioners represent this work (“unofficial branding discourse”). Through our analysis, we show that whereas the official branding discourse represents computing and I.T. as a field where women are valued, unofficial branding discourse represents this field as hostile to women. We then propose three avenues through which these contradictions can be managed: (1) acknowledging the challenges expressed by practitioners, while simultaneously discussing how to foster a more inclusive occupational culture, (2) changing the primary goal of the campaign from increasing the number of women in computing and I.T. to making the culture of computing and I.T. less hostile, and (3) committing fewer resources into organized branding campaigns and more resources into direct organizational interventions that seek to make work environments inclusive.
