Relações entre os graus de abertura de atividades investigativas e o desenvolvimento de argumentos por estudantes do ensino fundamental / Relations between levels of inquiry and the development of arguments by for middle school students

Geraldi, Aline Mendes 05 May 2017 (has links)
O ensino de ciências por investigação representa um importante caminho para a promoção da alfabetização científica. A argumentação é uma das principais habilidades que podem ser desenvolvidas por meio dessa abordagem de ensino, e também aproximar os estudantes do processo da construção do conhecimento científico. O presente trabalho tem o objetivo de investigar relações entre diferentes graus de abertura de atividades investigativas e a qualidade de argumentos desenvolvidos ao longo desse processo. Ele foi realizado no contexto de Iniciação Científica Júnior, com estudantes do ensino fundamental II. Foram propostas duas aplicações das atividades investigativas: uma chamada de sequencial, respeitando a ordem sequencial proposta na literatura, dos graus 1 ao 3 de abertura; e outra, chamada de invertida, em que as atividades foram propostas dos graus 3 ao 1. As análises foram conduzidas com base em duas ferramentas: uma fundamentada no padrão argumentativo de Toulmin (TAP), proposta por Osborne, Erduran e Simon (2004), que caracteriza a qualidade estrutural dos argumentos, e outra, que avalia a qualidade do conhecimento científico utilizado para embasá-los, adaptada do trabalho de Zohar e Nemet (2002). As análises apontaram que os estudantes são capazes de desenvolver argumentos ao se envolverem em atividades investigativas. Porém, alguns fatores influenciaram na qualidade desses argumentos, como o grau de abertura das atividades e os comandos presentes em seus enunciados. Os argumentos construídos envolveram pelo menos dois componentes do TAP, principalmente nas atividades de maior grau de abertura. Porém, identificou-se a dificuldade de os estudantes introduzirem os seguintes elementos: qualificador e refutação. Nas duas formas de aplicação, tanto em relação à qualidade estrutural quanto à do conhecimento científico, os argumentos de mais qualidade foram identificados nas atividades de graus 2 e 3 de abertura, as quais fomentavam maior protagonismo dos estudantes. Logo, as atividades investigativas não proporcionam uma maior qualidade dos argumentos quando propostas de maneira gradual. Os resultados evidenciam a importância das atividades investigativas, em seus diferentes graus de abertura, como propostas que fomentam e qualificam a argumentação no ensino de ciências. / The inquiry-based science education represents an important way for the scientific literacy. Argumentation is one of the main skills that can be developed through this teaching approach, and also bring students closer to the process of building scientific knowledge. This study has the objective of investigating relations between different levels of inquiry activities and the quality of arguments developed throughout this process. It was carried out in the context of Scientific Initiation, with middle school students. Two methods of the investigative activities were proposed: one called \"sequential\", respecting the sequential order proposed in the literature, from levels 1 to 3; and the other, called \"reversed\", in which the activities were proposed from levels 3 to 1. The analyzes were conducted on the basis of two tools: one based on the Toulmin argumentative pattern (TAP), proposed by Osborne, Erduran and Simon (2004), that characterizes the structural quality of the arguments, and another, that evaluates the quality of the scientific knowledge used to support them, adapted from the work of Zohar and Nemet (2002). The analyzes pointed out that students are able to develop arguments by engaging in inquiry activities. However, some factors influenced the quality of these arguments, like the levels of inquiry and the commands present in their statements. The arguments developed by students involved at least two components of the TAP, mainly in the more open levels. However, we identified that it was difficult for students to introduce the elements qualifier and rebuttal. In both forms of application, in terms of structural quality and scientific knowledge, the highest quality arguments were identified in the levels 2 and 3 of inquiry, which provided more autonomy for the students. Therefore, inquiry activities do not provide a higher quality of arguments when proposed in a gradual manner. The results show the importance of inquiry based activities, in their different levels, to foment and qualify the argumentation in science education.

Formação de professores reflexivos : uma experiência compartilhada /

Siqueira, Regina Aparecida Ribeiro. January 2009 (has links)
Orientador: João Antonio Telles / Banca: Dilma Maria de Mello / Banca: Simone Reis / Banca: Maria Rosa R. M. de Camargo / Banca: José Carlos Miguel / Resumo: Esta tese é uma investigação qualitativa que está fundamentada na concepção teórico-metodológica da Pesquisa Narrativa de Clandinin e Connelly, na Formação do Professor Reflexivo de Donald Schön e na Hermenêutica Filosófica de Gadamer. Em seu acabamento estético (tomando este adjetivo como substantivo foulcaultiano, estética da existência), fundamenta-se na concepção de "saber de experiência" de Larrosa. Nesta pesquisa o que está em suspensão é a vivência da pesquisadora como profissional da educação, cuja história é narrada, reconstruída e revivida, assim como, as histórias da participante, com quem a pesquisadora, de uma forma peculiar, compartilha suas "conversas reflexivas", seus objetos de estudo (relatos e histórias). A tese aqui defendida é a de que a construção do conhecimento pessoal e prático do professor também se dá ao se narrar as histórias de sua experiência profissional e interpretar palavras faladas e escritas - ações estas que são maneiras privilegiadas de acesso à consciência, entendida como abertura (ato intencional) em direção à compreensão do mundo como rede de relações. Assim, este trabalho teve como objetivos gerais (a) resgatar e reviver as histórias da vida pessoal, acadêmica e profissional da pesquisadora envolvida com o exercício da docência num curso de Letras; e (b) resgatar e reconstruir as histórias de vida acadêmica e profissional de uma outra professora, também formadora de professores de Letras, ex-aluna do referido curso. A tese ilustra a relevância teórico-metodológica da pesquisa narrativa para a reflexão e para a transformação da prática profissional dos professores. Os dois estudos aqui contidos, trazem as "conversas reflexivas" e a interpretação hermenêutica como instrumentos de ação social e profissional para o compartilhamento dos sentidos produzidos...

Clandinin and M.F. Connelly, on the Education of the Reflective Teacher of D. Schön, and on Gadamer's Philosophical Hermeneutics. From its aesthetical point of view (by taking this adjective as a foucaultian noun - the aesthetics of existence), the thesis is grounded on Larossa's concept of "knowledge derived from experience". The study focuses on the researcher's lived experiences as a professional in the field of Education. Her stories, as well as those of her participant become the foci of her study and they are narrated, reconstructed and relived in a peculiar way - they are shared by means of "reflective conversations". The thesis here sustained is that the construction of teachers' personal practical knowledge occurs when they tell the stories of their professional experiences and when they interpret the words that are spoken and written. Such actions are privileged ways to access consciousness, here understood as an opening (an intentional act) towards the understanding of the world as a network of relationships. The general objectives of this study, therefore, were (a) to recover and to relive the stories of the personal, academic and professional life of the researcher during her teaching practice in an undergraduate course of Letters; and (b) to recover and to reconstruct the academic and professional stories of another teacher, who is a teacher educator as well, and one of the researcher's former students in that course. The thesis illustrates the theoretical-methodological relevance of Narrative Inquiry to the reflection and transformation of teachers' professional practices. The two studies that are reported here bring "reflective conversations" and the hermeneutic interpretation as instruments of professional and social...

Význam tradičních a netradičních hospodářských zvířat / Traditional and nontraditional farm animals and their importance to human life

Procházka, Jiří January 2012 (has links)
The Abstract The main purpose of my thesis is to make summary of conventional and unconventional livestock and their importace to man. My thesis brings in survey of the most significant kinds of breeds and their economic exploitation. A separate section is devoted to Czech breeding of essential kinds of livestock in reference to their conditions and animal production capacity. Out of unconventional groups of livestock, the attention is devoted to birds from out superorder runners. The importace of meat in man's nutrition is widely discussed. As a part of thesis, a public inquiry was compiled and analysed. It was interpreted on samples of students and workers of educational institutions. The inquiry discovers the influence of respondents'demografic field and other circumstances upon meat consummation. As a suplement to the biology education at primary and secondary schools, a CD- ROM is made containing questions to systematic zoology of birds from among superorder runners. Key words: domestication, livestock, runners, meat, inquiry

No. of bitstreams: 1 Raquel_texto_completo.pdf: 4554269 bytes, checksum: 31b7a7e875a4461d29d0d14f512012b0 (MD5) Previous issue date: 2011-07-08 / Corn (Zea Mays L.) contributes significantly to the human being nourishment because of its nutritional characteristics. However, these characteristics also support fungus growing, which during their secondary metabolism produce toxic substances, named mycotoxins. Among mycotoxins, found more frequently in corn grains and derived products, aflatoxins B1, B2, G1 and G2 can be found and are also rated as cancer developers for human beings, as well as animals. Considering the diversity of sub products from this grain and that most of them is daily on the table of the Brazilian population, this research has the goal of evaluating the safety of corn derivates traded in the city of Cascavel Paraná, focusing on identifying the risk of the population's exposition to aflatoxins. Initially, a population survey was done to check which corn derivates products are the most consumed in the city of Cascavel Paraná, through the application of a questionnaire to the population, stratified into four categories: children (between 2 to 9 years old), teenagers (between 10 to 18 years old), young adults (between 19 to 59 years old) and elderly (above 60 years old). The city was divided into five geographical parts: East, West, North, South and downtown, and in each one of the regions one large supermarket was selected randomly and defined as the place to apply the questionnaires. After carrying out this survey, four samples of each one of the three most consumed corn products were collected. Collection was done every 15 days at the chosen supermarkets. Such samples were submitted to microbiological quality (fungus scoring) physical chemical (moist, ashes, acidity, proteins and lipids levels) and toxicological (identification and quantification of aflatoxins B1, B2, G1 and G2) tests. After finishing these analyses, the likely daily ingestion for AFB1 was estimated with the goal of checking if population was exposed to harms caused by these substances. From the population survey, it was observed that the most consumed corn derivates in the city were corn flour, popcorn and corn starch. Microbiological tests performed in those samples couldn t be analyzed as a pattern indicating quality in the products, considering the absence of a current legislation on this aspect. However, it was observed cultures similar to yeasts in the corn flour harvests whereas fungi similar to genus Aspergillus were noticed in popcorn cultures. Physical chemical tests identified that all samples were suitable to human consumption, considering the evaluated aspects. As for aflatoxins presence, subgroup B1 was detected only in one sample of corn starch, under concentration of 1 μg/kg, or in an amount under the limit recommended to current legislation. In risk analyses, an IDPM of AFBI was estimated to all population categories and the people category identified as eminently in risk were children, with IDPM varying from 0,0963 t 0,1438 ng/kg body weight/day. The conclusion was that even the population layers that acquired products with low aflatoxins incidence and amount, the risk regarding harms of this substance must be periodically checked, considering that in this research only one sample was positive for AFB1. However, IDPM for children was considered going nearly beyond limit. / O milho (Zea mays L.) contribui de forma significativa para a alimentação do ser humano, em virtude de suas características nutricionais. Em contrapartida, estas mesmas características também favorecem o crescimento de determinados fungos, os quais, durante seu metabolismo secundário, produzem compostos tóxicos denominados micotoxinas. Dentre as micotoxinas encontradas com maior frequência em grãos de milho e produtos derivados, estão as aflatoxinas B1, B2, G1 e G2, classificadas como substâncias carcinogênicas para o ser humano e também para animais. Considerando a diversidade de subprodutos oriundos deste grão, e que a maioria está presente diariamente na mesa da população brasileira, este trabalho teve por objetivo avaliar a segurança alimentar de produtos derivados de milho comercializados no município de Cascavel Paraná, com ênfase em identificar o risco de exposição desta população às aflatoxinas. Inicialmente foi realizado um inquérito populacional para verificar quais são os produtos derivados de milho mais consumidos no município de Cascavel Paraná, por meio da aplicação de um questionário à população deste município, estratificada em quatro categorias: crianças (2 a 9 anos), adolescentes (10 a 18 anos), jovens/adultos (19 a 59 anos) e idosos (60 anos ou mais). O município foi dividido em cinco quadrantes geográficos (leste, oeste, norte, sul e centro), e em cada uma das regiões foi selecionado, de maneira aleatória, um supermercado de grande porte, definido então como o local para aplicação dos questionários. Após a finalização do inquérito populacional, foram coletadas quatro amostras de cada um dos três produtos derivados de milho mais consumidos no município. Estas amostras foram submetidas a testes de qualidade microbiológica (contagem de fungos), físico-química (umidade, cinzas, acidez, teor de proteínas e lipídios) e toxicológica (identificação e quantificação de aflatoxina B1, B2, G1 e G2). Após o término destas análises, estimou-se a Ingestão Diária Provável Média (IDPM) para AFB1, com o objetivo de verificar se a população estava exposta aos malefícios ocasionados pela ingestão deste composto. A partir do inquérito populacional, identificou-se que os produtos derivados de milho mais consumidos no município eram o fubá, a pipoca e o amido de milho. Os ensaios microbiológicos realizado nestas amostras não puderam ser analisados como parâmetro indicador de qualidade destes produtos, tendo em vista a ausência de uma legislação em vigência quanto a este aspecto, porém, salienta-se que nas culturas de fubá foram visualizadas culturas semelhantes a leveduras, enquanto que, nas culturas de pipoca, verificou-se a presença de colônias de fungos semelhantes ao gênero Aspergillus. Os ensaios físico-químicos identificaram que todas as amostras estavam adequadas para o consumo humano, quanto aos aspectos avaliados. Quanto à presença de aflatoxinas, o subgrupo B1 foi detectado somente em uma amostra de amido de milho, na concentração de 1 μg/kg, ou seja, quantidade inferior ao limite preconizado pela legislação vigente. Na análise de risco, estimou-se a IDPM de AFBI para todas as categorias populacionais analisadas, e o público identificado como eminentemente em risco foram as crianças, com IDPM variando de 0,0963 a 0,1438 ng/kg peso corpóreo/dia. Concluiu-se que, mesmo em populações que adquiram produtos com baixa incidência e quantidade de aflatoxinas, o risco quanto aos malefícios deste composto deve ser periodicamente observado, tendo em vista que neste estudo apenas uma amostra foi positiva para AFB1, entretanto, a IDPM para as crianças foi considerada limítrofe.

A co-operative inquiry into counselling and psychotherapy trainers' inter- and intra-personal concerns and challenges in a higher education context

Carver, Elizabeth V. January 2017 (has links)
Key Aim: The purpose of this study was to examine complex concerns and challenges encountered by counselling and psychotherapy trainers, and support them to deliver a consistent, relationship-centred learning approach within Higher Education (HE). Background: Counselling and psychotherapy training is central to regulating practice, however, studies conceptualising trainers’ concerns and challenges in the United Kingdom (UK) are sparse. Literature generally evaluates trainer challenges from a professional competence and/or gatekeeping perspective. Little evidence exists identifying problems connected with ‘professionalisation’. Aims and Objectives: The aim was to evaluate trainers’ multidimensional unease that can hinder working relationships. The intention was to: explore difficult patterns of behaviour and group dynamics in the ‘training alliance’; explore trainers’ perceptions and experiences when confronted with gatekeeping issues; collaboratively develop strategies to enhance trainers’ learning experience; examine the processes needed to sustain these strategies; and identify the lessons learnt to inform practice, education, and research. Approach and Methods: A qualitative, co-operative inquiry approach enabled trainers to question their situated and propositional knowledge, reconcile professional challenges, allay concerns about individual fitness to practice, and provide alternative responses to students, peers, and managerial hierarchies in HE and professional bodies. This approach has a political and social element, according with personal desire to make change. Thematic analysis uncovered new insights, expanded or modified principles and re-examine accepted interpretations during 8 inquiry sessions with 5 experienced trainers, and 3 associated workshops. A primarily iterative and inductive process of immersion, involved reflexive engagement, and sharing of data with trainer/practitioners. Findings: 6 overarching themes were identified: Trying to Make Sense of Significant Events; Negotiating Conflict and Incongruity in Training Groups; Navigating Inherent Challenges within Counsellor Training Teams; Teaching as a Never-Ending Challenge; Organisational Constraints and Challenges; and Contemplating Individual Connection in a Collaborative Context. Discussion and Conclusion: Findings supported previous research suggesting trainers require training, and that trainers’ concerns and challenges are interlinked; beginning with interpersonal challenges that subsequently impact on trainers’ professional and intra-personal sense of identity. Co-operative inquiry can benefit programme teams in terms of the co-construction of trainers’ realities and dynamic negotiation of meaning. Co-researchers’ knowledge and confidence in responding to potential conflict in training was enhanced. To achieve the best outcome, this knowledge needs implementing in practice; programme team involvement is a prerequisite, and support is required by professional bodies and HE to ensure ethical training practice in the face of student disgruntlement, management demands in HE and from professional accrediting bodies.

Plody podle způsobů jejich šíření - výukový materiál pro ZŠ / The fruits according to their spreading - an educative material for the primary schools

MIKLASOVÁ, Lucie January 2019 (has links)
The aim of this diploma thesis was to summarize the issue of different types of seed / fruit propagation and to propose teaching material containing elements of inquiry based education. In the presented research proposal, pupils focused on finding out how to spread the seeds / fruits through their own process. The pupils worked with the worksheet, a description of the selected plants and the presented tools. The research task was carried out in four schools. The pre-test was conducted with seven grade students and final testing with seventh-grade students. Even though selected pupils met for the first time with this type of learning, they were able to build their own practice and discuss each other's findings.

Detecting students who are conducting inquiry Without Thinking Fastidiously (WTF) in the Context of Microworld Learning Environments

Wixon, Michael 09 April 2013 (has links)
In recent years, there has been increased interest and research on identifying the various ways that students can deviate from expected or desired patterns while using educational software. This includes research on gaming the system, player transformation, haphazard inquiry, and failure to use key features of the learning system. Detection of these sorts of behaviors has helped researchers to better understand these behaviors, thus allowing software designers to develop interventions that can remediate them and/or reduce their negative impacts on student learning. This work addresses two types of student disengagement: carelessness and a behavior we term WTF (“Without Thinking Fastidiously”) behavior. Carelessness is defined as not demonstrating a skill despite knowing it; we measured carelessness using a machine learned model. In WTF behavior, the student is interacting with the software, but their actions appear to have no relationship to the intended learning task. We discuss the detector development process, validate the detectors with human labels of the behavior, and discuss implications for understanding how and why students conduct inquiry without thinking fastidiously while learning in science inquiry microworlds. Following this work we explore the relationship between student learner characteristics and the aforementioned disengaged behaviors carelessness and WTF. Our goal was to develop a deeper understanding of which learner characteristics correlate to carelessness or WTF behavior. Our work examines three alternative methods for predicting carelessness and WTF behaviors from learner characteristics: simple correlations, k-means clustering, and decision tree rule learners.

Teacher Experiences in Highly Impacted Schools That Produce Happiness

Lund, Brittany Nicole 01 April 2018 (has links)
Teachers represent a large percentage of the workforce in the United States, yet there is a high demand for teachers every year due to a large number of teachers exiting the profession (Ingersoll, 2001). Staying beyond the first five years is a feat nearly half of the teachers in the United States do not accomplish which leads to problems within the school community (Ingersoll, 2002; Ingersoll, 2004). Through an exploration of the positive stories of teachers' experiences this study identifies some of the common themes found within those stories that led teachers to greater happiness in their profession. While this study provides important information regarding specific experiences of teacher happiness, it is also a closer look at a lesser-known but powerful tool of Narrative Inquiry, story cycles.
