Preservice Teachers\u27 Use of Lesson Study in Teaching Nature of Science

The purpose of this study was to explore preservice teachers’ lived experiences in a lesson study focused on teaching and learning nature of science (NOS). The body of knowledge about shifting pre- and in-service novice NOS understandings is substantial. The focus of science education research is now exploring ways to move these informed NOS understandings into classroom practice (Abd-El-Khalick & Lederman, 2000b). The research questions guiding the study were (a) how do preservice teachers’ understandings of NOS shift as a result of the lesson study experience?, and (b) how does the reflective practice that occurs in lesson study influence preservice teachers’ transition of NOS tenets into classroom practice? The participants in this study represented a sample of graduate preservice teachers, who were part of a middle and secondary science teaching alternative certification program in a southeastern university. In the first summer semester of this certification program, the participants were immersed in reform based science instruction; a section of which included NOS teachings (INTASC, 2002). In the following semester, participants were placed in a practicum setting; where the exploration of the preservice teachers’ teaching of NOS was supported through the modified lesson study framework. Data sources included the Views on Nature of Science – Form B (VNOS-b), interviews, and lesson study portfolios. Analysis of NOS understandings was guided by instruments found in literature associated with the VNOS-b (Lederman et al., 2002) and reflection (Ward & McCotter, 2004). Results showed successful transfer of NOS into classroom practice using the modified lesson study framework, with less success in the deepening of participants’ NOS understandings. Of particular significance was that results indicated a deepening of NOS pedagogical content knowledge for those participants functioning at higher levels of reflection. The study’s results’ contributes to two knowledge bases. First it provides insight to how lesson study can be used in the United States in alterative teacher preparation programs. Second, it contributes to what is understood about how to support the transition of NOS understandings into classroom practice

"I'm not sure how much this was about music:" Networks, Locations and Rituals of Identity in Pittsburgh's Grassroots Music and Arts Scene

Scenes are dynamic social relationships and experiences that are comprised of networks, locations, and rituals. Scene networks form in recognizable meeting places around activities such as live music shows, bike collectives, drag performances and gambling rings. This paper explores how cultural producers (i.e. band members, DJs, event organizers) perceive and use networks, locations and rituals in Pittsburgh's grassroots music and arts scene. Whereas previous research examines th experience of a single scene, this study explores the many ways cultural producers activate a variety of scenes under the same umbrella. This study examines how predominately white scene networks perceive and benefit from gentrification while also attending to how gender and sexuality affect where scene events are held. Women and queer identified artists do not have the same options as their heterosexual male counterparts when it comes to creating scene events in places opened by urban revitalization projects. This study also demonstrates that the rituals cultural producers engage are particular to the identities they seek to enact. Cultural producers use rituals of identity to deconstruct hegemonic constructions of gender and sexuality. Through performance rituals, participants empower stigmatized social identities

Superstars and Misfits: Two Pop-trends in the Gender Culture of Contemporary Evangelicalism

This paper examines gender in two forms of mediated contemporary Protestant evangelicalism in the United States: a male-dominated punk network, called Misfits United, and a women’s group studying Beth Moore’s Bible study, It’s Tough Being a Woman (ITBAW). While the appearance and performance styles of these two groups are drastically different, both support gender hierarchies in similar ways. Misfits United and Moore’s ITBAW present the gender of their Christian God as flexible, even transformative, and in effect open up discursive space to conceptualize gender on non-traditional grounds. Paradoxically, however, both reinforce traditional gender roles by emphasizing what distinguishes God from His creation: the gendered constraints of human biology

How and why the presence of social category diversity dictates procedures during mediation.

Through a multiple case study of the perceptions' of four mediators, this dissertation addresses how and why social category diversity dictates mediation procedures. The researcher delves into the world of governmental, non-governmental and military environments to provide viewpoints that capture a diverse audience. This literature review covers areas such as: group dynamics, self and social identification, diversity, conflict, alternate dispute resolution, discrimination, mediation, affirmative action and equal employment opportunity (EEO).The researcher discovered that three out of four mediators felt that social category diversity did not affect the mediation process. She found that gender diversity had the greatest impact on the mediation process. The study also adds richness to the current theory by bringing to life and giving a face to the mediators behind the scenes.Despite increasing efforts to address diversity, it remains a topic of discussion in most workgroups. Diversity has been considered a double-edged sword creating conflict in some cases, but mediating it in others. It is what Oprah Winfrey defines as "hard to wrap your brain around." Diversity can be surface level or non-surface level, but either can create the greatest conflict or mediate the most volatile environment

Knowledge Summary 27: Death reviews: maternal, perinatal and child

Many maternal, perinatal and child deaths are preventable and progress towards Millennium Development Goals 4&5, to reduce child mortality and improve maternal health, has been insufficient in many parts of the world. Well-implemented death reviews provide opportunities to examine the circumstances surrounding a woman’s or child’s death, and improve the delivery of health services to prevent such deaths in the future. Several types of review processes exist to evaluate deaths in diverse settings, given different data availability and levels of service delivery. Both consistent surveillance and effective response are needed to ensure that maternal, perinatal and child deaths are identified and reviewed, so that recommendations can be made, and action can be taken to prevent further deaths

Rebellious Religion: Christian Hardcore and Muslim 'Taqwacore' Punk Rock

This study shows how U.S. Christian Hardcore and Muslim ‘Taqwacore’ (taqwa means ‘god consciousness’ in Arabic) youth fuse traditional religions and punk rock music outside of religious institutions. It is part of a new cultural turn in the sociological study of religion that regards religion and secular culture as potentially interactive and mutually reinforcing. I examine the process by which both groups adapt D.I.Y. (do-it-yourself) hardcore punk to make religion their own; how they present themselves as religious/punk in subcultural settings; and how they define themselves internally as well as externally. To understand how Christian Hardcore and Taqwacore youth bridge religion and punk, I collected ethnographic data from intensive interviews, participant observations, surveys of audience members, and artifacts such as albums, films, images, newspaper articles, and websites about these two music scenes. I find that Christian Hardcore and Taqwacore youth both draw on the oppositional aspects of hardcore punk to combine religion and punk. Yet their relationships to religious and social institutions shape how they use hardcore punk. Christian Hardcore youth are influenced by the white Protestant evangelical institutions that support their music as a ministry. They oppose the “mainstream church” that condemns their punk music and the “anti-Christian” punks who reject them for being Christian. Taqwacores face a much different set of challenges. They are rejected from traditional Islamic institutions, American society, and white dominated punk. Consequently, they oppose the very idea of Islam, America and punk. In conclusion, I argue that subcultural Christian and Muslim youth rebel against religious/secular boundaries to make religion their own and in effect challenge how scholars commonly study religion and religious identity

IMAGING T1, T2 AND MYELIN WATER FRACTION IN THE POST-MORTEM MULTIPLE SCLEROSIS CENTRAL NERVOUS SYSTEM

PhDThe subject of this thesis is the use of Magnetic Resonance (MR) Imaging to quantify biometric MR indices in the Multiple Sclerosis (MS) fixed post-mortem central nervous system (CNS) tissue. Evaluating these indices in fixed tissue allows for the use of histology to verify the findings of MRI. However, it must first be discovered if the indices can be evaluated in fixed post-mortem spinal cord tissue. There is very little literature in this specific area, though some in the fixed brain, the results of which have been assumed to be equivalent in the spinal cord without proof. Therefore, the methodology must first be verified before the consideration of any index as useful and translatable to in-vivo spinal cord. This thesis concentrates on the evaluation of MR relaxometry methods using the indices T1 and T2 by themselves and to evaluate the myelin content of fixed post-mortem CNS tissue. The Carr-Purcell-Meiboom-Gill (CPMG) and Multicomponent Driven Equilibrium Single Pulse Observation of T1 & T2 (mcDESPOT) sequences are used to calculate T1, T2 and the Myelin Water Fraction (MWF) which is believed to be proportional to myelin content in the CNS. This is performed at 3T in a clinical scanner and at 7T in a small animal and wholebody scanner. The methods are first evaluated for use in fixed post-mortem CNS tissue. The two myelin measurement methods are then compared to histological staining if appropriate and where available to verify that the results obtained are proportional to myelin content. The T1 and T2 values in fixed tissue were found to be shortened in fixed tissue, T2 values were so short as to be at the limits of measurement by a clinical scanner, and values converged in white and grey matter, and therefore contrast was found to be limited between these tissues. Proton density images provided the most contrast between tissues. However, even with shortened T2 values, the CPMG sequence was able to identify the myelin water component in fixed tissue. The mcDESPOT algorithm struggled to separate the myelin water component due to clinical scanner limitations and the shortened, converging T1 and T2 values. However, the mcDESPOT algorithm was successful in discerning the myelin water component in the high signal situation of a small bore 7T peclinical scanner. An evaluation was then made of the usefulness of these indices for translation into clinical imaging. The CPMG sequence was found to be proportional to myelin content under all conditions, and therefore useful for disease monitoring in demyelinating diseases. The mcDESPOT sequence, was found to be proportional to myelin in some conditions, and is likely to be useful for monitoring myelination, though the sequence could not be fully validated in this thesis.Barts and the London Charit
