Science education in urban settings: Seeking new ways of praxis through critical ethnography

The challenges faced in urban science education are deeply rooted in the ongoing struggle for racial, class and gender equity. Part of this struggle is tied to huge differences in class and involves making more equitable the distribution of resources. Another part of this struggle is tied to the rich diversity of children who attend urban schools and involves generating new ways of understanding, valuing, and genuinely incorporating into school‐based practices the culture, language, beliefs, and experiences that these children bring to school. Thus, this article argues that to address these two challenges—and indeed to achieve a more just science education for all urban students— explicitly political research methodologies must be considered and incorporated into urban education. One potential route for this is critical ethnography, for this kind of methodology emerges collaboratively from the lives of the researcher and the researched and is centrally about praxis and a political commitment to the struggle for liberation and in defense of human rights. In making this argument, I have drawn from stories from my own research with homeless children. © 2001 John Wiley & Sons, Inc. J Res Sci Teach 38: 899–917, 2001     

Family disruption and academic functioning in urban,black youth

The purpose of this study was to examine from an ecological perspective the relationships between multiple levels of family disruption and children's academic functioning in a sample of 390 urban, Black adolescents at age 14. Subjects in this cohort have been followed longitudinally since before their birth. Data from previous assessments at birth and age 7 years allowed for control of important correlates in this analyses. Examination of this unique sample, using multisource data collection procedures, provides important information about the many family disruptions among urban, low‐income families and the effects of these disruptions on academic outcomes. Results revealed several consistent findings, the most notable of which is that, when parents were married, adolescents demonstrated significantly higher grades, mediated through paternal involvement. Of all variables studied, the role of fathers in the lives of these adolescents was the most influential on academic outcomes. In this unique sample, even variables such as involvement with child protective services were not significantly related to outcomes after important control variables were factored into analyses. Results of this study have important implications for future research and for prevention and intervention efforts in urban, at‐risk samples. Emphasis is made for work in the school context, particularly for school psychologists. © 2011 Wiley Periodicals, Inc.     

Focus Group Effects on Field Practicum Preferences

ABSTRACT

During the coming years the need for professionals to work with the nation's elders will increase several fold. This will place a great responsibility on university educational programs to prepare enough qualified future professionals to work in the greatly expanding field of gerontology. Prior research has identified several nonacademic and academic experiences that influence a student's decision to become gerontological professionals. One area that has been omitted from this work concerns focus groups. This article reports on the impact that observing a relatively simple and inexpensive focus group of professional geriatric practitioners can have on field practicum preferences among advanced undergraduate social work students at a large Texas state university. Findings indicate that observing a focus group significantly influences students' practicum preferences for working with elders, thereby setting them on a trajectory for a career in geriatrics.     

Researching Telemedicine: Capturing Complex Clinical Interactions with a Simple Interface Design

Telemedicine has been shown to be an effective means of managing follow-up care in chronic diseases such as depression. Exactly why telemedicine calls work, however, remains largely unknown because there are no adequate research tools to describe the complex communicative interactions in these encounters. We report here an ongoing project to investigate the efficacy of telemedicine in depression care, arguing that technical communication specialists have unique contributions to make to this kind of research.     

Assessing Students With Disabilities: Issues and Evidence

Historically, many students with disabilities were excluded from large-scale assessments. Recent federal and state policy initiatives, including the most recent reauthorization of the Individuals With Disabilities Education Act, require that the large majority of students with disabilities be included in the statewide assessments used in accountability systems. Although most observers agree that educational outcomes for students with disabilities were inadequate before the new policies were implemented, the research undergirding the new policies is limited. The reforms have spurred a rapid increase in relevant research, but more and improved research is needed. This article reviews the status of research on issues that are central to the new reforms and recommends directions for future research.     

The prevention of child abuse and neglect: A review of the literature with recommendations for application

Families at high risk for inadequate parenting can be identified during the perinatal period, or during later health care visits. Effective intervention can be implemented for these special families. During the maternity ward stay, intervention can include early delivery room contact, rooming-in arrangements, and increased teaching sessions on child care. The primary physician can provide frequent office visits, telephone contacts and helpful advice during acute illnesses and developmental phases which might precipitate child abuse. The physician can seek assistance from outreach workers such as public health nurses, lay health visitors, and child welfare caseworkers. Community prevention programs such as parenting classes, Parent's Anonymous groups, crisis nurseries and crisis hotlines should also be integrated into the family's treatment. When provided in concert, these actions can stabilize most dysfunctional families.     

Stages in the History of Algebra with Implications for Teaching

In this article, we take a rapid journey through the history of algebra, noting the important developments and reflecting on the importance of this history in the teaching of algebra in secondary school or university. Frequently, algebra is considered to have three stages in its historical development: the rhetorical stage, the syncopated stage, and the symbolic stage. But besides these three stages of expressing algebraic ideas, there are four more conceptual stages which have happened along side of these changes in expressions. These stages are the geometric stage, where most of the concepts of algebra are geometric ones; the static equation-solving stage, where the goal is to find numbers satisfying certain relationships; the dynamic function stage, where motion seems to be an underlying idea, and finally, the abstract stage, where mathematical structure plays the central role. The stages of algebra are, of course not entirely disjoint from one another; there is always some overlap. We discuss here high points of the development of these stages and reflect on the use of these historical stages in the teaching of algebra. Commentary from a Mathematics Educator Bill Barton.
