En nombre de un amor imaginario y los orígenes de la República del Ecuador (Dossier: Bicentenario, rastros y revelaciones de la Independencia)

El autor analiza esta novela histórica de Jorge Velasco Mackenzie, en torno a los orígenes de la nación ecuatoriana, entre la historia y la fábula. Reflexiona sobre el proceso de escribir como una forma de interpelar presupuestos consagrados, valores, símbolos e identidades. Handelsman destaca que el trabajo de la Misión Geodésica Francesa, de 1736, cambió la cosmovisión de la sociedad colonial ecuatoriana, escolástica, por otra de carácter más empírico, pero que el nuevo motor del saber moderno trajo también distorsiones y omisiones de otras verdades (como el que los indígenas perdieran su protagonismo milenario como conocedores de su hábitat). Pone en relieve, igualmente, la imposibilidad de expresar en una segunda lengua lo que se vive en geografías ajenas. Personaje importante es Isabel Godin, quien no puede liberarse del mundo oscuro, complejo y ambivalente que constituye la memoria. En suma, la novela desmitifica la autoridad de las ciencias naturales y físicas, y abre la posibilidad de repensar, reescribir y resignificar la historia del país.

Briefing: re-engineering the city 2020–2050 – urban foresight and transition management

Cities may be responsible for up to 70% of global carbon emissions and 75% of global energy consumption and by 2050 it is estimated that 70% of the world's population could live in cities. The critical challenge for contemporary urbanism, therefore, is to understand how to develop the knowledge, capacity and capability for public agencies, the private sector and multiple users in city regions systemically to re-engineer their built environment and urban infrastructure in response to climate change and resource constraints. Re-Engineering the City 2020–2050: Urban Foresight and Transition Management (Retrofit 2050) is a major new interdisciplinary project funded under the Engineering and Physical Science Research Council's (EPSRC) Sustainable Urban Environments Programme which seeks to address this challenge. This briefing describes the background and conceptual framing of Retrofit 2050 project, its aims and objectives and research approach.

Undersökande arbetssätt i NO-undervisningen i grundskolans tidigare årskurser

This thesis deals with the use of inquiry-based approaches in primary school science. The aim is to investigate the goals and purposes that are constituted by the curriculum and by the teachers in interviews and through their teaching in the classroom. The results are used to develop conceptual tools that can be used by teachers’ in their work to support students’ learning of science when using an inquiry-based approach. The thesis is comprised of four papers. In paper one a comparative analysis is made of five Swedish national curricula for compulsory school regarding what students should learn about scientific inquiry. In paper two 20 teachers were interviewed about their own teaching using inquiry. Classroom interactions were filmed and analyzed in papers three and four, which examine how primary teachers use the various activities and purposes of the inquiry classroom to support learning progressions in science. The results of paper one show how the emphasis within and between the two goals of learning to carry out investigations and learning about the nature of science shifted and changed over time in the different curricula. Paper two describes the selective traditions and qualities that were emphasized in the teachers’ accounts of their own teaching. The results of papers three and four show how students need to be involved in the proximate and ultimate purposes of the teaching activities for progression to happen. The ultimate purposes are the scientific purposes for the lesson (as given by the teacher or by the curriculum), whereas the proximate purposes are the more student-centered purposes that through different activities should allow the students to relate their own experiences and language to the ultimate purpose. The results show the importance of proximate purposes working as ends-in-viewin the sense of John Dewey, meaning that the students see the goal of the activity and that they are able to relate to their experiences and familiar language.

Possíveis implicações epistemológicas do conceito de interação não-ordinária para a noção de sincronicidade de Jung

Este estudo teórico visa propor, em sentido mais amplo, a noção de totalidade não-fragmentada como referencial de "visão do mundo" e, consequentemente, de construção do conhecimento. Para tanto, faz-se necessário estabelecer as perspectivas de um redimensionamento epistemológico, objetivando edificar os fundamentos para a viabilização de uma teoria sistêmica do conhecimento, baseada na noção de totalidade. Tal teoria se reporta, em âmbito mais estrito, aos chamados sistemas autogênicos não-ordinários, que são sistemas especiais, voltados a se constituir como uma alternativa de interpretação para os sistemas humanos. Nesse sentido, tem-se por objetivo orientar-se para a síntese de uma conceituação especial para o domínio do "vivo", em detrimento da vigência de uma linguagem ainda "fisicalista", oriunda da transferência de conceitos da ciência física para as outras áreas do conhecimento. Pretende-se, assim, que a conceituação dos chamados "sistemas autogênicos não-ordinários" se constitua como passível de ser aplicada ao âmbito da psicologia e, mais especificamente, aos fenômenos da psique. Para se alcançar esta meta, procurar-se-á exemplificar a procedente utilidade dos sistemas autogênicos à psicologia através de tentativa, ainda incipiente, de aplicabilidade da noção de interação não-ordinária (foco central desses sistemas) ao princípio de sincronicidade de Jung. A fim de realizar os objetivos supramencionados, este trabalho prende-se, em sua primeira parte, tanto a um estudo das fontes de constituição do conhecimento no ocidente quanto a uma apreciação das tendências epistemológicas da ciência contemporânea, no sentido de situar adequadamente a questão da proposta da noção de totalidade não-fragmentada. De forma contígua a este fim, procede-se a pesquisa da obra de certas personalidades do cenário do conhecimento no ocidente, por se terem, reconhecidamente, norteado segundo um referencial de totalidade.

Modelling Mathematical Reasoning in Physics Education

Many findings from research as well as reports from teachers describe students' problem solving strategies as manipulation of formulas by rote. The resulting dissatisfaction with quantitative physical textbook problems seems to influence the attitude towards the role of mathematics in physics education in general. Mathematics is often seen as a tool for calculation which hinders a conceptual understanding of physical principles. However, the role of mathematics cannot be reduced to this technical aspect. Hence, instead of putting mathematics away we delve into the nature of physical science to reveal the strong conceptual relationship between mathematics and physics. Moreover, we suggest that, for both prospective teaching and further research, a focus on deeply exploring such interdependency can significantly improve the understanding of physics. To provide a suitable basis, we develop a new model which can be used for analysing different levels of mathematical reasoning within physics. It is also a guideline for shifting the attention from technical to structural mathematical skills while teaching physics. We demonstrate its applicability for analysing physical-mathematical reasoning processes with an example.

The Impact of Greek Affiliation on Students’ Educational Objectives: Longitudinal Change in Clark-Trow Educational Philosophies

Change in 4,119 students' freshman to senior ratings of four educational philosophies (vocational, academic, collegiate, and nonconformist) provided four measures of educational impact. Repeated measures analyses of variance compared changes in philosophy as a function of Greek affiliation, controlling for sex, historical era, major, parents' education, scholastic aptitude, and academic motivation. Small but significantly different degrees of change in the collegiate and nonconformist philosophies suggested that Greek affiliation increased social interests and inhibited some forms of intellectual interests. These small differences across all students masked the moderating effect of major. In the nonconformist philosophy, for example, the Greek × major interaction reflected substantial Greek–independent differences among humanities majors, and progressively smaller differences or reversals among social science, physical science, and engineering majors. Possible interpretations of this interaction are offered.
