Uppfattningar om utomhuspedagogik hos lärare i grundskolans årskurs 4-6

Cassel, Louise January 2009 (has links)
<p>The use of out-door pedagogy in the school has been frequently high-lighted during recent years. To which extent out-door education was practised in the school depends on the opinions among the active teachers. The aim of this study was to examine the opinions on out-door pedagogy among teachers in classes 4-6 of the elementary school and to find out to which extent the teacher used out-door teaching. The study was based on qualitatively structured interviews with 4 teachers having different lenght of teaching experience. The results of the interviews showed that the teachers had different opinions on the definition of out-door pedagogy. They claimed that out-door pedagogy was a way to explore nature, to link the out-door environment to theoretical subjects and to give the children an increased understanding on nature. In daily teaching, out-door pedagogy was practiced to a varying extent depending on weather, season, schedule and the teacher´s own experience of out-door teaching. The teachers stressed that out-door pedagogy was an interdisciplinary teaching method that offered a possibility to integrate different subjects.</p>

No. of bitstreams: 1 DISSERTACAO RAILMA.pdf: 4231634 bytes, checksum: 754476049de60a236bc760be9a58535a (MD5) Previous issue date: 2011-07-13 / Fundação de Amparo à Pesquisa do Estado do Amazonas / The piquiá (Caryocar villosum) belongs to the Caryocaraceae family; it is considered a social tree, because it provides fruit, raw material for making objects and income for the people of the rainforest, allowing the study of the establishment of the interrelationship between man and forest. Due to its conservation by farmers, this study investigated the social and environmental conservation practices of piquiá (C. villosum (Aubl.) Pers.) through phytosociological and ethnobotanical knowledge of farmers, testing the occurrence of seed dormancy in piquiá (C. villosum) and are described the means of management practiced by farmers in Manacapuru, in Amazonas. In this study, we adopted a systemic approach, structuring the research as a case study. The experiences that comprise this work are carried out through focus groups, who manage the piquiá, which include farmers and parataxonomists. In the end, data were collected through the following techniques: (1) semistructured interview (2) diary, (3) cultural trail, (4) literature searches, (5) experimental testing to verify the seed dormancy of this species. Data analysis was done qualitatively and quantitatively. Six interviews with farmers and with two parataxonomists were conducted; during this phase the two species were cited (C. villosum and C. glabum) with the name of piquiá. Protection practices of piquiá (C. villosum) by farmers stimulate phenotypic plasticity of the species, yet the selection of specific features was not verified. Currently, the plant occurs with the first seeds to germinate without worrying about the characteristics that individuals will make when they grow up. The long and uneven seed germination due to dormancy and embryonic cutaneous existing piquiá seed, but can be circumvented by partial removal of the integument and the application of inducers plant. Finally, we conclude that both systems work as germplasm banks in situ, so it is important to keep them. The piquiá in the forest system provides individuals in the wild, with wild gene; in agroforestry, the fruit has a better social and economic use and it benefits of protecting human activities, and may acquire certain characteristics. One suggestion is to encourage the maintenance of legal reserve, to enable farmers to become experimenters, wrapping them in protective practices and management and enabling them to maintain the ethnic knowledge. The conservation manifests itself in daily life. Therefore it is important to understand how human communities are related to plant community. / O piquiá (Caryocar villosum) pertence à família Caryocaraceae, é considerada uma árvore social, pois fornece fruto, matéria-prima para fabricação de objetos e renda para os moradores da floresta tropical, possibilitando o estudo do estabelecimento da inter-relação entre o homem e a floresta. Tendo em vista a conservação do piquiá por agricultores, o presente trabalho objetivou estudar as práticas de conservação socioambiental do piquiá (C. villosum (Aubl.) Pers.); por meio de conhecimentos fitossociológicos e etnobotânicos dos agricultores, testando a ocorrência de dormência em sementes de piquiá (C. villosum); e descrevendo as formas manejo praticadas por agricultores da Região dos Lagos Parú e Calado, Manacapuru - Amazonas. Neste estudo adotou-se a abordagem sistêmica, estruturando a pesquisa como um Estudo de Caso. As experiências que compõem este são realizadas por grupos focais, que manejam o Piquiá sendo eles: agricultores familiares e parataxonomistas, para tal os dados foram coletados por meio das seguintes técnicas: (1) entrevista semi-estruturada, (2) diário de campo, (3) trilha cultural, (4) pesquisas bibliográficas, (5) ensaio experimental para verificar a dormência em sementes da espécie em estudo, a análise dados foi de forma qualitativa e quantitativa. Foram realizadas 6 entrevistas com agricultores e 2 com parataxonomistas, durante as quais foram citadas duas espécies (C. villosum e C. glabum) com o nome de piquiá. Práticas de proteção ao piquiá (C. villosum), realizadas pelos agricultores estimulam a plasticidade fenotípica da espécie, contudo a seleção de características específicas não foi verificada, atualmente, o plantio ocorre com as primeiras sementes a germinar, sem a preocupação com as características que as os indivíduos vão apresentar quando crescerem. O longo e desuniforme período de germinação deve-se a dormência tegumentar e embrionária existente em sementes de piquiá, porém pode ser contornada, com a remoção parcial do tegumento e com aplicação de indutor vegetal. Ao final, podemos concluir que os sistemas florestais e agroflorestal, funcionam como bancos de germoplasma in situ, sendo importante mantê-los. O piquiá no sistema florestal fornece indivíduos em estado silvestre, com gene silvestre; em sistemas agroflorestais o piquiá tem maior aproveitamento social e econômico, se beneficia como proteção antrópica podendo adquirir características, uma sugestão é incentivar a manutenção da reserva legal, possibilitar aos agricultores tornarem-se experimentadores, envolvendo-os em práticas de proteção e de manejo e os possibilitando a manutenção do etnoconhecimento. A conservação se manifesta no cotidiano das pessoas por isso é importante conhecer como comunidades humanas se relacionam com uma comunidade vegetal.

Preference, Resistance to Change, and Qualitatively Different Reinforcers

Podlesnik, Christopher Aaron 01 May 2008 (has links)
Preference for one stimulus context over another and resistance to disruption within those contexts are a function of the conditions of reinforcement arranged within those contexts. According to behavioral momentum theory, these measures are converging expressions of the concept of response strength. Most studies have found that preference in concurrent chains and resistance to change are greater in contexts presenting higher rates or larger magnitudes of reinforcement. The present series of experiments attempted to extend behavioral momentum theory by examining whether differences in reinforcer type affect relative response strength with rats lever pressing for different types of food. In Experiment 1 of Chapter 2, several nonuniform disrupter types were examined that provided free access to a food type that was the same as one reinforcer type. Responding decreased more in the context presenting the same type of reinforcer as the disrupter, suggesting that many traditional disrupters (e.g., satiation) are inappropriate for examining how reinforcer type impacts response strength. Therefore, extinction was used throughout the remainder of the experiments to more uniformly disrupt responding across contexts. In Experiment 2 of Chapter 2, resistance to extinction was assessed when food pellets and a sucrose solution maintained responding across contexts. Moreover, relative reinforcer type was manipulated by changing the sucrose concentration across conditions. Relative response rates were systematically affected by changing sucrose concentration, but relative resistance to extinction was not. In Experiment 3 of Chapter 2, qualitative difference between reinforcers was enhanced and preference also was assessed to provide a converging measure of response strength. Preference and relative response rates were systematically affected, but relative resistance to extinction again was not. Finally, in Chapter 3, relative reinforcer rate and type were manipulated while assessing preference and resistance to extinction using the matching law. Preference, but not resistance to extinction, consistently was affected by changes in reinforcer rate and type. Systematic deviations in sensitivity and bias, however, suggested that different reinforcer types interacted with reinforcer rate. Overall, these findings suggest that the overall context of reinforcement, including interactions between different reinforcer types, should be considered when assessing preference and relative resistance to change.

Technik und Bildung in der verwissenschaftlichten Lebenswelt

Lumila, Minna 02 June 2023 (has links)
Die Studie versucht, Husserls Modell einer nicht-wissenschaftlichen Lebenswelt für pädagogische Untersuchungen zum Verhältnis von Technik und Bildung in der verwissenschaftlichen Welt zu öffnen. Sie diskutiert Entwicklungsprobleme der Spätmoderne unter pluralen Fragestellungen und führt Ansätze und Traditionen zusammen, die unterschiedliche Wege zur Weiterentwicklung der modernen Bildungstheorie beschritten haben. Im Zentrum steht die Frage, wie moderne Technik einerseits als lebensweltliche Entfremdung des Menschen problematisiert und andererseits als Produkt menschlicher Freiheit und Weltgestaltung gewürdigt werden kann. In vier Kapiteln werden die methodischen Ansätze und Antworten vorgestellt, die der Philosoph und Pädagoge Eugen Fink (1905–1975), der Philosoph Martin Heidegger (1889–1976), der Philosoph und Erziehungswissenschaftler Theodor Litt (1880–1962) und der Soziologe Helmut Schelsky (1912–1984) auf die Frage nach dem Verhältnis von Bildung und Technik gegeben haben. Im Durchgang durch ihre Positionen wird ein Konzert erarbeitet, dessen Originalität darin liegt, Abstimmungsprobleme von Bildung, Technik und Lebenswelt aus postdualistischer, praxistheoretischer sowie posthumanistischer Perspektive zu thematisieren. / The study attempts to open Husserl's model of a non-scientific lifeworld for pedagogical investigations of the relationship between technology and “Bildung” in the scientific world. It discusses developmental problems of late modernity under plural questions and brings together approaches and traditions that have taken different paths to the further development of modern “Bildungs”-theory. The central question is how modern technology can be problematized on the one hand as the alienation of human beings from the world of life and on the other hand be appreciated as a product of human freedom and the shaping of the world. Four chapters present the methodological approaches and answers that philosopher and educator Eugen Fink (1905–1975), philosopher Martin Heidegger (1889–1976), philosopher and educationalist Theodor Litt (1880–1962), and sociologist Helmut Schelsky (1912–1984) have given to the question of the relationship between education and technology. In the course of their positions, a concert will be developed whose originality lies in addressing the coordination problems of “Bildung” (education), “Technik” (technology) and “Lebenswelt” (lifeworld) from a post-dualist, praxis-theoretical as well as post-humanist perspective.
