Mean structure of the North Atlantic subtropical permanent pycnocline from in-situ observations

In the north Atlantic subtropical gyre, the oceanic vertical structure of density is characterized by a region of rapid increase with depth. This layer is called the permanent pycnocline. The permanent pycnocline is found below a surface mode water ,which are ventilated every winter when penetrated locally by the mixed layer. Assessing the structure and variability of the permanent pycnocline is of a major interest in the understanding of the climate system because the pycnocline layer delimits important heat and anthropogenic reservoir. Moreover, the heat content structure translate into changes in the large scale stratification feature, such as the permanent pycnocline. We developed a new objective algorithm for the characterization of the large scale structure of the permanent pycnocline (OAC-P). Argo data have been used with OAC-P to provide a detailed description of the mean structure of the North-Atlantic subtropical pycnocline (e.g.: depth, thickness, temperature, salinity, density, potential vorticity). Results reveal a surprisingly complex structure with inhomogeneous properties. While the classical bowl shape of the pycnocline depth is captured, much more complex pycnocline structure emerges at the regional scale. In the southern recirculation gyre of the Gulf Stream Extension, the pycnocline is deep, thick, the maximum of stratification is found in the middle on the layer and follow an isopycnal surface. But local processes influence and modify this textbook description and the pycnocline is characterized by a vertically asymmetric structure and gradients in thermohaline properties. T/S distribution along the permanent pycnocline depth is complex and reveals a diversity of water masses resulting from mixing of different source waters. We will present the observed mean structure of the North-Atlantic subtropical permanent pycnocline and relate it to physical processes that constraint it.

O colégio Pedro II e os livros didáticos

O presente trabalho investiga a análise dos critérios de seleção e escolha do livro didático de História pelos professores da rede pública de educação do Colégio Pedro II da cidade do Rio de Janeiro, no período entre 2010-2012, período dos processos de escolha do livro didático, promovidos pelo Programa Nacional do Livro Didático – PNLD e o Programa Nacional do Livro do Ensino Médio. Através da análise dos critérios de seleção do livro didático de história, dos professores da rede pública de educação do Colégio Pedro II da cidade do Rio de Janeiro, propomos compreender os processos educativos formais e não formais que envolvem o fazer docente, nesse caso a própria elaboração do currículo, e as influências do livro didático diretamente nos contextos educacionais, com base nas pesquisas que visam habilitar o historiador-docente a ter capacidade de auxiliar o ensino dos discentes de forma a contribuir significativamente para um ensino pautado em métodos e pesquisas que possibilitem o próprio historiador-docente a desenvolver seu trabalho não somente através de pesquisas, mas também práticas, alcançando a práxis de um currículo pautado em pesquisas historiográficas.

Geschichtsbilder sehen. Narrative Formen als Gegenstand des Lernens mit Geschichten

Im Zuge einer ikonischen Wende in den Geisteswissenschaften hat das Visuelle an Bedeutung für den kritischen Umgang mit Bildungsmedien wie Schulbücher und deren Inhalte gewonnen. Während frühe Arbeiten vor allem eine Kritik an der Vorstellung des Bildes als Anhängsel des Texts übten, erlaubte die Ausweitung des Bildbegriffs eine Annäherung verschiedener semiotischer Ansätze. Am Beispiel von Geschichtsschulbüchern stellt sich der Aufsatz die Frage inwieweit (Schulbuch)Narrative als Bilder verstanden werden können und wie ein solches Verständnis neue methodische Perspektiven auf das Lernen mit dem Bildungsmedium eröffnet.

„Geschichtsbilder“ in österreichischen Lehrmaterialien 1978/79: Sagbarkeits- und Zeigbarkeitsregeln am Beispiel „Anschluss“

Dieser Beitrag untersucht geschichtspolitische Strategien der Darstellung des „Anschlusses“ in österreichischen Lehrbüchern und -materialien Ende der 1970er-Jahre. Dabei wird auf die Bedeutungsproduktion durch das Zusammenwirken der textlichen und visuellen Ebene fokussiert. Vor dem Hintergrund der allgemeinen geschichtspolitischen Entwicklungen in Bezug auf die Auseinandersetzung mit der NS-Zeit in Österreich soll der potenzielle Beitrag dieser Materialien zur Ausbildung des österreichischen Bildgedächtnisses diskutiert werden.

Welchen Grad an visueller Aufmerksamkeit widmen Lernende den Abbildungen in Geographieschulbüchern?

Dieser Beitrag widmet sich der Erforschung des Grades visueller Aufmerksamkeit, mit dem Lernende Abbildungen auf Geographieschulbuchseiten betrachten. In einer explorativen Stichprobe wurden die Blickbewegungen von 20 Probanden/Probandinnen (Gymnasium 15-17 Jahre, Studierende 20-24 Jahre) mithilfe von Eye Tracking beim Betrachten verschiedener Geographieschulbuchseiten aufgezeichnet. Ein visueller Fokus auf Text und geringe visuelle Aufmerksamkeit für Fotos wurde festgestellt. Anhand der Eye-Tracking-Aufzeichnungen werden mögliche Herausforderungen im Lernprozess mit Abbildungen im Geographieschulbuch erläutert, die aus der Gestaltung der Abbildungen resultieren könnten. Hierfür werden Erkenntnisse aus pädagogischer Psychologie, Visueller Kommunikation und Schulbuchforschung herangezogen. (DIPF/Orig.)

Propuesta de Enseñanza-aprendizaje en Estudios Sociales para el Quinto año de Educación Básica de la escuela “Alfonso María Borrero”, año lectivo 2014-2015

El trabajo de investigación se basa en una propuesta de enseñanza-aprendizaje en Estudios Sociales basado en actividades con enfoque pedagógico crítico y constructivista aplicado en el desarrollo del tercer bloque del Quinto Año EGB, durante el periodo Lectivo 2014-2015 de la Escuela “Alfonso María Borrero.” La Educación Tradicional basada en el conductismo que se fundamenta en el uso del libro escolar y la memorización persiste en las Escuelas pese al esfuerzo del Ministerio de Educación por cambiar estas prácticas, por lo que esta propuesta busca probar que la práctica pedagógica y didáctica desde enfoques alternativos es factible pese a presiones de tiempo o exigencia en la presentación de calificaciones. Metodológicamente, se realizó un diagnóstico en el que se observaron las prácticas tradicionales; luego se organizaron dos grupos de trabajo, el primero en el que se aplicó la propuesta y el segundo que continuó con la labor normal; finalmente, se analizaron los resultados. Estos demostraron que las actividades de una propuesta constructivista y crítica alternativa a la tradicional pueden ser cumplidas en los tiempos establecidos y que los resultados académicos son mejores.

A MATLAB program for the computation of the confluent hypergeometric function Φ2

We here present a sample MATLAB program for the numerical evaluation of the confluent hypergeometric function Φ2. This program is based on the calculation of the inverse Laplace transform using the algorithm suggested by Simon and Alouini in their reference textbook [1].

Pre-packaged multimodal resources and second language teacher agency

In the present globalised and digitised world, availability of a plethora of pre-packaged classroom resources for English Language Teaching (ELT) seems Lo threaten ESL/EFL teachers' professional agency in the language classroom. Whilst it is difficult to envisage the viability of these materials presented for a global audience of learners (Liyanage & Bartlett, 2008), the practice also seriously limits ESL/EFL teachers' agency in the application of their pedagogic content knowledges. The selection and implementation of pre-packaged materials by language teachers arc due either to personal choice or to mandated regulations and established practices(Birch & Liyanage, 2004; Liyanage & Bartlett, 2008). This paper reports the reflections of thirty overseas ESL/ EFL teachers enrolled in postgraduate programmes on (i) their use of pre-packaged materials in language classrooms in contexts where such practice is mandated or is the nom1, and, (ii) the effect of this practice on their professional agency in the Jru1guage classroom.

How online learning in an engineering-physics course helped us flip the classroom

Distance education has developed in the past 25 years or so as a way of supplying education to people who would not have access to local college education facilities. This includes students who live in remote regions, students who lack mobility, and students with full-time jobs. More recently this has been renamed to "online learning". Deakin University in Australia has been teaching freshman engineering physics simultaneously to on-campus and online students since the late1990's. The course is part of an online Bachelor of Engineering major that is accredited by the Institution of Engineers Australia.* In this way Deakin answers the call to provide engineering education "anywhere, anytime."**The course has developed and improved with the available educational technology. Starting with printed study guides, a textbook, CD-ROMS, and snail-mail, and telephone/email correspondence with students, the course has seen the rise of websites, online course notes, discussion boards, streamed video lectures, web-conferencing classes and lab sessions, and online submission of student work. Most recently the on-campus version of the course has shifted from a traditional lecture/tutorial/lab format to a flipped-classroom format. The use of lectures has been reduced while the use of tutorials and practical exercises has increased. Primary learning is now accomplished by watching videos prepared by the lecturer and studying the textbook.Offering this course for several years by distance education made this process considerably easier. Most of the educational "infrastructure" was already in place, and the course's delivery to a non-classroom cohort was already established. Thus many elements of the new structure did not have to be produced from scratch. Improvements to the course website and all the course material has benefited all students, both online and on-campus.The new course structure was delivered for the first time in 2014, has run for two semesters, and will continue in 2015. Student learning and performance is being measured by assignment and exam marks for both on-campus and off-campus students. Students are also surveyed to gauge how well they received the new innovations, especially the video presentations on the lab experiments. It was found that student performance in the new structure was no worse than that in the older structure (average on-campus grades increased 10%), and students in general welcomed the changes. Similar transitions are being implemented in other courses in Deakin's engineering degree program.This presentation will show how physics is taught to online students, outline the changes made to support flipping the on-campus classroom, and how that process benefited the off-campus cohort.

Introduction: why pedagogy of school mathematics is important for us?

This textbook is designed to empower pre-service teachers to teach mathematics in schools in China. In this chapter, we briefly described the history of mathematics teaching in the West and in China and the history of mathematics education becoming a science. Then we reviewed some hot research issues associated with mathematics education that occurred from the mid-1950s. We selected four research in literature as examples to illustrate the research methods that PSTs could try in future. We hoped to help PSTs understand that having solid mathematical knowledge is not enough to be an excellent teacher. They need to learn professional knowledge and deal with teaching issues basing on research.
