Collaboration and teacher development: Unpacking resistance, constructing knowledge, and navigating identities

This article presents a study of the Collaboration Centers Project (CCP), which is a pseudonym for a three-year, federally-funded program that focused on helping in-service teachers better address the needs of English language learners (ELLs) in their classrooms. The CCP is important to study because of its clear intention to integrate real teachers--their understandings, voices, selves, and practices--into professional development by providing an experiential, collaborative and school-centered context for ongoing reflection on teachers\u27 practice. It is important to understand the complexities of teacher development in the context of a project that sought to break with the short-term transmission model that Richardson (2003) described as the still dominant approach to in-service professional development. By investigating the ongoing collaboration created by the program, the authors seek to provide a multi-layered understanding of how collegial and collaborative professional development affects teachers and how teachers affect professional development. Therefore, their purpose is to add to the existing research that explains the complexity of teacher collaboration by uncovering the meaning of teacher resistance and by providing an in depth look into how a group of teachers co-constructed knowledge and negotiated their identities over time

To determine diurnal variations in the physical and biological state of Lake Garda in early spring, high-resolution measurements were made of the vertical distribution of temperature and fluorescence in the upper 100 meters during 5–7 March 2014. In this paper, the results of these measurements are presented and a preliminary analysis that focuses on the connection between the vertical mixing coefficient K_T and the chlorophyll-a (chl-a) concentration is given. From these first direct measurements of turbulence-related quantities in Lake Garda, it is found that mixed-layer values of K_Tdecrease, while surface chl-a concentrations increase, over the day. Variations in K_Tcan be connected to the changes in the surface wind stress, while variations in chl-a are negatively correlated with the amplitude of K_T. In addition, satellite observations of the surface chl-a concentration are analysed to test their use for the calibration of the fluorescence measurements and also for their potential utility in remotely determining vertical mixing in the upper layers of the lake

Primary skin fibroblasts as a model of Parkinson's disease

Parkinson's disease is the second most frequent neurodegenerative disorder. While most cases occur sporadic mutations in a growing number of genes including Parkin (PARK2) and PINK1 (PARK6) have been associated with the disease. Different animal models and cell models like patient skin fibroblasts and recombinant cell lines can be used as model systems for Parkinson's disease. Skin fibroblasts present a system with defined mutations and the cumulative cellular damage of the patients. PINK1 and Parkin genes show relevant expression levels in human fibroblasts and since both genes participate in stress response pathways, we believe fibroblasts advantageous in order to assess, e.g. the effect of stressors. Furthermore, since a bioenergetic deficit underlies early stage Parkinson's disease, while atrophy underlies later stages, the use of primary cells seems preferable over the use of tumor cell lines. The new option to use fibroblast-derived induced pluripotent stem cells redifferentiated into dopaminergic neurons is an additional benefit. However, the use of fibroblast has also some drawbacks. We have investigated PARK6 fibroblasts and they mirror closely the respiratory alterations, the expression profiles, the mitochondrial dynamics pathology and the vulnerability to proteasomal stress that has been documented in other model systems. Fibroblasts from patients with PARK2, PARK6, idiopathic Parkinson's disease, Alzheimer's disease, and spinocerebellar ataxia type 2 demonstrated a distinct and unique mRNA expression pattern of key genes in neurodegeneration. Thus, primary skin fibroblasts are a useful Parkinson's disease model, able to serve as a complement to animal mutants, transformed cell lines and patient tissues

Promising Pedagogical Practices for Emergent Bilinguals in Kindergarten: Towards a Mathematics Discourse Community

In the current U.S. context, it is relevant to disseminate research that portrays in detail how bilingual teachers create challenging and safe mathematics learning environments for emergent bilinguals. It is critical to identify pedagogical approaches that foster emergent bilinguals’ participation in mathematics conversations and discourse practices where language is considered a pedagogical resource. This is possible when teachers understand that young Latino/a students come to school with a wide range of cognitive and linguistic tools, which they can use to help them make sense of problems posed in the classroom. Using case study methodology, we define and provide a detailed portrayal of a bilingual kindergarten teacher´s mathematics pedagogical practices. Specifically we discuss: (a) the use of authentic mathematics stories, (b) the integration of multimodal representation of problem solving, and (c) collective thinking and representation of problem solving solutions. In addition, we analyze how the teacher fosters practices that use language as a learning resource. Finally, we argue that these practices promote a mathematics discourse community and that pedagogy of confidence, care, and understanding is at the core of this teacher’s instructional approach

Youth Digital Cultural Consumption and Education

Media and technological devices function as socializing agents during children’s leisure and entertainment time. Drawing from the theory of cultural consumption, a socio educational approach to students’ digital practices, and media literacy, this qualitative study seeks to explore and describe students’ cultural consumption profile. The authors explore the representations and meanings of digital practices of public school students of a predominately working class neighborhood situated in the periphery of Buenos Aires, Argentina. Findings highlight different aspects of youth cultural consumption profile. Two themes were identified: a) children use computers for a multiplicity of different activities enacting multitasking practices; and b) children develop new forms of digital practices for social digital interaction that are expressed in the “need” to be connected, the production and use of shared codes and the establishment of ambivalent relations with social media platforms. Implications for education are explored

Young Latino students\u27 learning in problem-based reform Mathematics classrooms: Developing mathematical thinking and communication

This study explores how Latino first grade students develop mathematical problem solving and communication in their native language. Problem types came from Cognitively Guided Instruction (Carpenter et al. 1999) and were embedded in students’ cultural and linguisticexperiences. Findings show students solved a wide range of CGI problems and developed confidence, flexibility, and sophistication in their strategies and explanations

A regola d’arte. Istruzioni e modelli per l’architettura carceraria tra Settecento e Ottocento

The 19th century constitutes a moment of rebirth for the field of treatises, also thanks to the impulse given previously by the Enlightenment movement in restoring faith in a scientific organisation of knowledge, based on the possibility of defining general rules applicable to a multiplicity of concrete cases. At the same time, social and cultural changes sparked off a vibrant debate on the reorganisation of the detention system, with a transformation of the concept of punishment that also affected the places deputed to it. The prison compounds themselves, conceived to offer a synthesis of the "rule of art", become, in turn, the basis for norms and standards, constituting a support for the training of architects and engineers: the most successful solutions are mentioned by eminent theorists, while drawings and descriptions flow into publications of various kinds that, as they spread, collaborated in a process of proto-globalisation of design approaches to large public buildings. Starting from the recognition of these sources, the contribution investigates the instances that guided the design of prison architecture in programmatic terms and the pragmatic rules into which they were translated, in order to identify, on the one hand, the general paradigms, and on the other, the individual peculiarities generated by contextual contingencies.Il contributo costruisce un percorso ragionato sulle diverse tipologie di fonti che hanno guidato l’edificazione delle carceri storiche.L’Ottocento costituisce un momento di rinascita per il genere della trattatistica, grazie anche all’impulso precedentemente dato dalla corrente illuminista nel rinnovare la fiducia in un’organizzazione scientifica del sapere, basata sulla possibilità di definire norme generali applicabili a una molteplicità di casi concreti.Parallelamente, profonde modificazioni sociali e culturali accendono un vivo dibattito sul riordino del sistema detentivo, con una trasformazione del concetto di pena che investe anche i luoghi a essa deputati.Gli stessi complessi carcerari, concepiti per offrire una sintesi della «regola d’arte», divengono, a loro volta, la base per norme e regolamenti, costituendo un supporto per la formazione di architetti e ingegneri: le soluzioni più riuscite vengono menzionate da illustri teorici, mentre disegni e descrizioni confluiscono in pubblicazioni di diversa natura che, diffondendosi, collaborano a un processo di proto-globalizzazione degli approcci progettuali alle grandi fabbriche pubbliche.Sebbene non tutti finalizzati alla formazione di studenti e tecnici, tali strumenti influenzano le scelte progettuali, coerentemente con le essenziali esigenze che la buona prigione deve soddisfare secondo i pensatori dell’epoca.Muovendo dalla ricognizione di queste fonti, il contributo si propone di indagare le istanze che hanno guidato in termini programmatici il progetto delle architetture detentive e le regole operative in cui esse si sono tradotte, al fine di identificare, da un lato, i paradigmi di carattere generale, dall’altro, le peculiarità individuali derivanti dalle contingenze contestuali.Infatti, se la letteratura manifesta una tendenza all’universale, attraverso la riduzione logica a categorie generali, i singoli episodi architettonici, nelle innumerevoli variazioni sul tema, evidenziano l’esistenza di spazi di libertà e modificazione di regole e modelli che il progettista può reinterpretare e adattare sulla base della propria sensibilità
