Against Conformity: Raphael Samuel

This paper is about the work of the historian and committed intellectual Raphael Samuel, a central figure of the British New Left. It considers his political and intellectual activities over a 30‐year period, and sets them in their changing context. It seeks to argue that in many respects Samuel's work provides means for rethinking educational history and contemporary educational politics.     

Ethical Perspectives on Body Donation Following Physician-Assisted Death

The increasing availability of physician-assisted death (PAD) has opened up a novel means of making donated bodies available for anatomical dissection. This practice has come to the fore in Canada, but is unlikely to be confined to that country as legislation changes in other countries. The ethical considerations raised by this development are placed within the framework of the ethical guidelines on body donation promulgated by the International Federation of Associations of Anatomists. The discussion centers on understanding the ethical dimensions of moral complicity, and whether it is accepted or rejected. If rejected it is possible to separate ethical concerns regarding PAD from subsequent use of donated bodies, as long as there is fully informed consent and complete ethical and procedural separation of the two. Openness about the origin of bodies for dissection is essential. Students should be instructed on the nuances of moral complicity, and consideration be given to those with moral doubts about PAD. Two issues are raised in considering whether these moves represent an ethical slippery slope: the attraction represented by obtaining relatively “high quality” bodies, and the manner in which organ donation following PAD has led to challenges to the dead donor rule. Although body donation raises fewer concerns, the ethical dimensions of the two are similar. The ethical constraints outlined here have the capacity to prevent an ethical slippery slope and constitute a sound basis for addressing an innovative opportunity for anatomists.     

Prevention: Necessary But Insufficient? A 2-Year Follow-Up of an Effective First-Grade Mathematics Intervention

We present first-grade, second-grade, and third-grade impacts for a first-grade intervention targeting the conceptual and procedural bases that support arithmetic. At-risk students (average age at pretest = 6.5) were randomly assigned to three conditions: a control group (n = 224) and two variants of the intervention (same conceptual instruction but different forms of practice: speeded [n = 211] vs. nonspeeded [n = 204]). Impacts on all first-grade content outcomes were significant and positive, but no follow-up impacts were significant. Many intervention children achieved average mathematics achievement at the end of third grade, and prior math and reading assessment performance predicted which students will require sustained intervention. Finally, projecting impacts 2 years later based on nonexperimental estimates of effects of first-grade math skills overestimates long-term intervention effects.

Interactives and Visitor Learning

Abstract Interactives—computers and other multimedia components, physical manipulatives (including whole‐body and tabletop activities), and simulations—occur in all types of museums. There is considerable interest in the nature of the learning that happens when visitors use interactives. Museum professionals have enlisted constructivist theory to support the notion that interactive elements are invaluable components of any exhibition experience, and are effective learning tools that enable active visitor engagement. Interactives are also seen as vital to sustaining institutional image and expanding institutional popularity. Despite the increasing use of interactives in exhibitions and the substantial investments being made in their design and maintenance, there is a paucity of research as to whether these constructivist assumptions are supported. There is little work exploring visitors' perceptions of specific types of interactives, or the role of interactivity in the visitor experience generally. Museum staff thus have a limited ability to make informed decisions about the level and type of interactivity that might enhance exhibition experiences. This paper describes a collaborative effort in 2001 by researchers at the Powerhouse Museum (PHM), Sydney; the Institute for Learning Innovation (the Institute), Annapolis, Maryland; and Curtin University of Technology (Curtin) and Scitech Discovery Centre (Scitech), both in Perth, Western Australia. This study investigated two aspects of interactivity: 1) visitor perceptions of interactivity in two different contexts, a museum and a science center; and 2) the types of short‐ and long‐term learning that resulted from use of interactives in these two institutions.     

Promoting toddlers' self-regulation and healthy eating habits among families living in poverty: A randomized controlled trial of Recipe 4 Success

The Recipe 4 Success preventive intervention targeted multiple factors critical to the health and well-being of toddlers living in poverty. This randomized controlled trial, which was embedded within Early Head Start home visits for 12 weeks, included 242 racially and ethnically diverse families (51% girls; toddler mean age = 2.58 years; data collected 2016–2019). Compared to parents in usual practice home visits, parents in Recipe 4 Success displayed greater sensitive scaffolding of toddlers' learning and more responsive food parenting practices (Cohen's d = .21–.30). Toddlers in Recipe 4 Success exhibited greater self-regulation and had healthier eating habits (Cohen's d = |.16–.35|). Results highlight the value of Recipe 4 Success in promoting parent and toddler behavior change that could have life-long benefits.     

Visual and cognitive processes contribute to age-related improvements in visual selective attention

Children (N = 103, 4–9 years, 59 females, 84% White, c. 2019) completed visual processing, visual feature integration (color, luminance, motion), and visual search tasks. Contrast sensitivity and feature search improved with age similarly for luminance and color-defined targets. Incidental feature integration improved more with age for color-motion than luminance-motion. Individual differences in feature search ( = .11) and incidental feature integration ( $$ = .06) mediated age-related changes in conjunction visual search, an index of visual selective attention. These findings suggest that visual selective attention is best conceptualized as a series of developmental trajectories, within an individual, that vary by an object's defining features. These data have implications for design of educational and interventional strategies intended to maximize attention for learning and memory.
