How do college students solve proportion problems?

Problems which could be solved using proportional reasoning were administered nationwide by college faculty to their own science classes during a three year period. The reasoning of more than 8000 students covering three sections of the country was classified as concrete, transitional, or formal using Piagetian categories. Data from the West closely replicated that from the Midwest on similar metric conversion tasks. Student performance changed noticeably with a different problem format. The percentages of students using a ratio formula, ratio attempt, or intuitive methods of solution held approximately constant over time, task, and section of the country. The data shows the use of additive and conversion methods of solution depends upon the problem presentation.     

Participation in an intergenerational service learning course and implicit biases

Biases against the elderly and people with disabilities can lead to discriminatory behaviors. One way to conceptualize attitudes toward the elderly and people with disabilities is through the differentiation of explicit (conscious) and implicit (unconscious) factors. Although both explicit and implicit attitudes and biases contribute to the full picture of peoples’ attitudes, explicit ideas alone may not accurately reflect people’s attitudes. This may be due to societal pressure to conceal explicit biases or the fact that often times, people are not aware they hold prejudiced views. The Implicit Association Test is a computer-based categorization task designed to assess implicit or unconscious attitudes. This test was used in in the current study to assess the impact of an intergenerational service-learning course. We designed this study to determine if greater exposure or contact with the elderly or people with disabilities might influence college students’ implicit attitudes. Pre- and post-assessment of participating students, using the Wilcoxon signed-rank test, found statistically significant decreased biases after participation. Results from this study that suggest participating in an intergenerational service-learning course can positively affect implicit attitudes. This is encouraging, especially because these attitudes are developed over a long period of repeated exposure, are consistently reinforced by cultural factors, and are notoriously difficult to change.     

Innovating for a cause: the work and learning required to create a new approach to healthcare for homeless people

Innovation occupies a pivotal place in our understanding of knowledge-based economies, and this is raising questions about sources of innovation, how it originates, and the role played by employees, work practices and learning. This paper explores these issues through case study research into a new approach to providing healthcare for homeless people in England, and by bringing together conceptual insights from the employee-driven innovation literature, and more broadly from social and practice-based learning theory and organisational theory. Applying these perspectives to our case enables illumination of the innovation as a process – not an event – and as an ongoing set of organisational practices that transcend their origins. Through our analysis we argue that the notion of ‘a cause’ is helpful in elucidating the impetus and the commitment to making the innovation happen (and go on happening). Our findings are presented under three themes: ‘establishing a cause’, ‘organising for innovation’, and ‘innovative capability in practice’. Building on these, we have identified five key inter-related dimensions which help conceptualise the work and learning that it took to create and (re-)enact the innovation and that we suggest may have relevance for understanding and characterising other employee-led innovations in and perhaps beyond healthcare.     

Fremde Blicke, eigene Wahrnehmungen

Schools share comparable curricula and follow regional and national institutional guidelines. In their materiality, however, the living spaces of schools bring forth a constant interaction on the part of its members with a given, distinctive space. In the process, school members shape and traditionalize a unique and distinctive culture in every school. Within their ongoing project, the authors seek to grasp the interpersonal and spatial complex constituted within a school culture. To document and understand the cultural specificity of individual schools, they have further developed qualitative research methods from the methodological repertoire of educational and cultural anthropological research. Building on the component of strangeness as a key component of ethnographic experience and insight, two methods were designed to complement the overall toolkit deployed within the project: guided walks and short term visits by individuals socialized in another culture. These methodological approaches promise new insights for research in schools as well as for other organizational and institutional cultures.     

Trust and transformational government: A proposed framework for research

This paper examines the concepts of trust and transformational government, both of which have been the subject of increasing attention in recent times. It explores what trust and transformation mean, or could mean, for government, governance and public administration and whether transformational government is just a feel-good phrase or a genuinely new departure. As part of this, the question of what precisely is being, or could be, transformed is examined. The results of this examination suggest that the expectation that technology-enabled change has the ability to increase citizen trust, thereby transforming government may be too high, but that more research is needed. A framework for such research is proposed.     

What makes a word difficult? Insights into the mental representation of technical terms

Learning from texts requires reflection on how far one has mastered the material. Learners use such metacognitive processes to decide whether to engage in deeper learning activities or not. This article examines how the lexical surface of specialist concepts influences their mental representation. Lexical encodings that are the concise wordings of a concept (e.g., tension headache or migraine for specific types of headache) provide immediate access to the underlying content. To understand learning contents appropriately, learners have to work on such lexical covers to gain insight into the underlying semantic meaning. It was assumed that a technical term??s origin (either German or classical Latin/Greek) is used systematically as a hint for further elaboration. 41 college students rated the difficulty, familiarity, competence, accessibility, and their knowledge of 17 German-language (GL) terms and their classical language (CL) synonyms. The influence of word frequency was controlled. As expected, results showed that GL terms were perceived to be less difficult than CL terms. Consequently, comprehension of these terms was rated more highly. Analyses of how lexical encoding influenced accuracy of participants?? comprehension judgments showed that participants?? comprehension ratings were less accurate for GL terms. Theoretical and practical implications for learning from written information are discussed.     

Does war contribute to family violence against children? Findings from a two-generational multi-informant study in Northern Uganda

After 20 years of civil war in Northern Uganda, the continuity of violence within the family constitutes a major challenge to children's healthy development in the post-conflict era. Previous exposure to trauma and ongoing psychopathology in guardians potentially contribute to parental perpetration against children and dysfunctional interactions in the child's family ecology that increase children's risk of maltreatment. In order to investigate distal and proximal risk factors of child victimization, we first aimed to identify factors leading to more self-reported perpetration in guardians. Second, we examined factors in the child's family environment that promote child-reported experiences of maltreatment. Using a two-generational design we interviewed 368 children, 365 female guardians, and 304 male guardians from seven war-affected rural communities in Northern Uganda on the basis of standardized questionnaires. We found that the strongest predictors of self-reported aggressive parenting behaviors toward the child were guardians’ own experiences of childhood maltreatment, followed by female guardians’ victimization experiences in their intimate relationship and male guardians’ posttrautmatic stress disorder (PTSD) symptoms and alcohol-related problems. Regarding children's self-report of victimization in the family, proximal factors including violence between adults in the household and male guardians’ PTSD symptom severity level predicted higher levels of maltreatment. Distal variables such as female guardians’ history of childhood victimization and female guardians’ exposure to traumatic war events also increased children's report of maltreatment. The current findings suggest that in the context of organized violence, an intergenerational cycle of violence persists that is exacerbated by female guardians’ re-victimization experiences and male guardians’ psychopathological symptoms.     

Child care quality: centers and home settings that serve poor families

The effects of center-based care on early development, outside of carefully controlled demonstration programs, appear to be positive yet often modest for children from low-income families. But little is known about variation in the quality of centers and preschools found among low-income neighborhoods. Evidence also remains scarce on the observed quality of home-based care, the settings that most children attend and into which large infusions of federal dollars are now directed. This paper reports on the observed quality of 166 centers and 187 nonparental home settings (including family child care homes and kith or kin providers) serving children in five cities situated in California, Connecticut, or Florida. Centers displayed higher mean quality as gauged by provider education and the intensity of structured learning activities, compared to home-based settings, but did not consistently display more positive child–provider interactions. Great variability among centers and home-based settings was observed, including between-city differences. Second, we found that contextual neighborhood attributes accounted for the quality of providers selected more strongly than family-level selection factors. Mothers with stronger verbal abilities (PPVT scores) did select higher quality centers; those employed longer hours each week relied on kith and kin providers with lower education levels. Interrelationships among different quality measures are detailed. The policy implications of such wide disparities in center and home-based care quality are discussed, including how states could more carefully strengthen regulatory or quality improvement efforts.     

Child Care Selection Under Welfare Reform: How Mothers Balance Work Requirements and Parenting

This paper examines the reasoning and experiences of mothers in selecting child care while trying to meet welfare-to-work requirements. Three theoretical positions that have been used to look at child care selection -rational choice, structuralist, and cultural - are examined and critiqued in light of a structural developmental psychology perspective. The paper then reports on semi-structured, open-ended interviews with seven mothers from three different ethnic groups—African- American, Anglo, and Latina—who range in age from 21 to 42. Interviews covered a 15-month period of time following the mothers' enrollment in a welfare- to-work program. The major finding is that mothers have hierarchically ordered criteria for evaluating child care possibilities, and the preeminent criteria is that they trust the child care provider to keep their children safe and well cared for. Structural constraints on the mothers choices are also analyzed. The findings in this article suggest that policy makers should focus on issues of trust and legitimacy of child care providers, as well as on more traditional concerns of supply and educational quality.
