Aprendizagem de conceitos químicos num curso EaD: contribuições da Teoria da Atividade / Learning of chemical concepts in a Distance Education course: contributions of Teaching Activity

João Ricardo Sanchez 03 December 2018 (has links)
Com a expansão da Educação a Distância (EaD), vários cursos tem sido oferecidos no formato digital, inclusive cursos superiores de Ciências. Em trabalhos anteriores, pautados na Teoria da Atividade de Leontiev, desenvolvemos Atividades Orientadoras de Ensino (AOEs) sobre identificação-separação de metais pesados e investigamos a potencialidade destas como proposta teórico-metodológica em um Curso presencial de Licenciatura em Química. A formação presencial em Química do pesquisador e a atuação como tutor junto ao curso EaD em uma Universidade Paulista, favoreceram a definição da questão central neste trabalho: na EaD, como essa atividade mobilizaria os estudantes em direção a aprendizagem do conhecimento químico?A fundamentação teórica deste trabalho baseia-se em trabalhos de Vigotski, Leontiev e Engeström. A pesquisa qualitativa foi a metodologia de pesquisa adotada, com destaque para a análise microgenética. O campo empírico foi o fórum de discussão virtual no qual as Atividades de Ensino (AEs) foram disponibilizadas. Este fórum na forma de AE foi desenvolvido com alunos da EaD em 7 cidades do Estado de São Paulo. Ao planejar a AE a distância, concentramos em não valorizar situações práticas experimentais como no Ensino presencial, pois na situação virtual, o aluno estaria sozinho durante o desenvolvimento da atividade e sem muitos recursos laboratoriais. Pudemos notar que a interação aluno-aluno foi menor na atividade a distância, pois a maior parte da discussão ocorreu a partir da interação com pesquisador/mediador.Os resultados evidenciaram que nos 8 grupos em que a AE foi desenvolvida, surgiram diversas palavras relativas aos temas estudados, direta ou indiretamente, e que o sistema de análise realizado apontou para importantes processos de elaboração conceitual, uma vez que alguns conceitos foram estabelecidos, outros foram questionados e refutados. No ensino presencial a aplicação da AOE teria sido analisada em maior parte do ponto de vista de cada indivíduo e acreditamos que esta caracterização tenha sido mantida na EaD. Todavia, as informações ou experiências sócio-culturais se mostraram mais evidentes no formato AE a distância em detrimento da AOE presencial / As the Distance Education (DE) becomes more popular many course are being offered in the on-line version, including Science degree courses. In previous papers, based on Leontievs Activity Theory, we developed Teaching Guiding Activities (TGAs) about the indentification-separation of heavy metals and investigated the potential of these TGAs as a theoretical-methodological proposal in a face-to-face Chemistry Teaching course. The researchers regular face-to-face Chemistry degree and his work as a monitor in the Distance Education course at São Paulo University helped defining this paper central question: in Distance Education, how would a TA engage students toward the learning of chemical knowledge ? The theoretical bases of this paper are the works developed by Vigotski, Leontiev and Engeström. The methodology used was the qualitative research, with focus on the Microgenetic Analysis. The empirical field was the on-line discussion forums, where the TAs were available. The TA/forum was developed with distance education students from 7 different cities in São Paulo State. When planning the TA-DE (TGA for the Distance Education), we focused on not having experimental practices as it is common in face-to-face courses because the student would be alone during the activity and would not have many laboratory resources. We could notice that in the distance activity the student-student interaction was not satisfactory as the participants would interact with the researcher/professor. The results made it evident that in the 8 groups, in which the TA was developed, several words appeared on the subjects studied, directly or indirectly, and that in the system of analysis carried out pointed to important processes of conceptual elaboration, some concepts were developed, some were questioned and/or refuted. At the face-to-face education the TA development would be analyzed mostly from the individual perspective and we believe that this characteristic was kept at the Distance Education. However, social-historical information or experiences were shown more during the development of the distance TA than in the face-to-face one

Expansive and transformative learning within volunteer training : a multiple case study of three UK health and social care charities

Darley, Sarah January 2016 (has links)
This research explores the learning of volunteers who are being trained to perform service-providing roles within UK health and social care charities. Within these charities, volunteers often perform complex roles in dynamic environments, supporting service users and addressing challenging causes. This thesis argues that the charity and voluntary environment offers certain affordances, and also constraints, that provide opportunities for transformative learning experiences. The limited previous studies on the learning of volunteers have tended to concentrate on training evaluations or informal learning 'on the job', resulting in an unhelpful formal/informal dichotomised approach to learning. The research proposes that this approach has been unable to offer a detailed insight into the learning experienced by volunteers within the training process. In particular, this dichotomised view has been unable to account for both the learning of scientific concepts, such as the specific health conditions these charities are addressing, and everyday experiences of both volunteers and service users that are integral to the learning process. To address this gap, the thesis draws upon Cultural-Historical Activity Theory (CHAT), which is an approach grounded in Hegelian dialectics. Specifically, the CHAT-informed theories of expansive learning (Engeström, 1987) and Transformative Activist Stance (TAS) (Stetsenko, 2008) are synthesised to examine how volunteers interact with and within the charity environment through practices of training. Through this perspective, learning is conceptualised as a form of individual and social transformation, which expands the possibilities for collective activity. Expansive learning and TAS have previously been drawn upon to provide insight into learning in the workplace and in projects of social change respectively. However, so far the theories have not been focused on learning within the charity and voluntary environment. A multiple case study of three health and social care charities based in North West England provides the empirical data for the research. Each charity addresses a complex health and social cause, including stroke, sexual violence and HIV, and relies on volunteers to help provide services. Multiple qualitative methods, including observations of training, charity staff interviews, along with interviews and focus groups with volunteers, allow a range of perspectives and positions to be taken into account in line with the epistemology of the study. Data are analysed through the process of abduction drawing upon a CHAT-informed theoretical framework. The thesis intends to contribute to knowledge in two main areas. Firstly, it aims to increase understanding of learning within volunteer training, including how learning in the charity environment can be supported, sustained and made meaningful to enable transformative experiences. Secondly, it aims to theoretically advance CHAT, and the charity and voluntary environment is presented as a fruitful setting for developing particular aspects of the theory, such as emotion and agency.

A Computer Model of Creativity Based on Perceptual Activity Theory

Blain, Peter J, N/A January 2007 (has links)
Perception and mental imagery are often thought of as processes that generate internal representations, but proponents of perceptual activity theory say they are better thought of as guided exploratory activities. The omission of internal representations in the perceptual activity account has led some to see it as computationally implausible. This thesis clarifies perceptual activity theory from a computational perspective, and tests its viability using a computer model called PABLO. The computer model operates in the Letter Spirit domain, which is a framework for creating stylistic variations on the lowercase letters of the Roman alphabet. PABLO is unlike other computer models of perception and mental imagery because it does not use data-structures to represent percepts and mental images. Mental contents are instead modelled in terms of the exploratory activity in which perceptual activity theory says they consist. PABLO also models the flexibility of imagery, and simulates how it can be harnessed and exploited by the system to generate a creative product. PABLO is a first attempt at an implementation of perceptual activity theory, but the results suggest that the theory is computationally viable, and that it has advantages over other theories of mental imagery in the context of creativity.

Collaborative learning in mathematics

Pietsch, James Roderick January 2005 (has links)
Doctor of Philosophy (PhD) / This study looked at the implementation of a collaborative learning model at two schools in Sydney designed to realise the principles recommended by reform documents such as the Principles and Standards for School Mathematics (NCTM, 2000) and policy documents including Numeracy, A Priority for All (DETYA, 2000). A total of 158 year seven and year eight students ranging in age from 12 to 15 years old from two schools participated in the study. In all, seven classroom teachers participated in the study each completing two topics using the collaborative learning model. Four research questions were the focus of the current study. Three research questions were drawn from eight principles identified in the literature regarding what constitutes effective mathematics learning. These questions related to the nature of collaboration evident in each classroom, the level of motivation and self-regulation displayed by students in the different types of classrooms and the relationship between learning mathematics within the collaborative learning model and real-world mathematics. A final research question examined the degree to which the concerns of teachers relating to preparing students for examinations are met within the collaborative learning model. Several different data collection strategies were adopted to develop a picture of the different forms of activity evident in each classroom and the changes that took place in each classroom during and after the implementation of the collaborative learning model. These included classroom observations, interviews with student and teacher participants, questionnaires and obtaining test results. Both exploratory and confirmatory factor analysis were used to reduce the data collected. Factor scores and test results were compared using t-tests, ANOVAs and Mann Whitney nonparametric tests. Data collected from interviews and classroom observations were analysed using a grounded approach beginning with the open coding of phenomena. Leont’ev’s theoretical approach to activity systems (1972; 1978) was then used to describe the changing nature of classroom activity with the introduction of the collaborative learning model. Within the collaborative classrooms there were a greater number of mathematical voices participating in classroom discussions, a breaking down of traditional roles held by teachers and students, and dominant patterns of collaboration evident in each classroom reflecting pre-existing cultural ways of doing. Furthermore, there was some quantitative evidence suggesting that student levels of critical thinking, self-regulation and help seeking increased and students were also observed regulating their own learning as well as the learning of others. Classroom practice was also embedded in the cultural practice of preparing topic tests, enabling students to use mathematics within the context of a work group producing a shared outcome. Finally, there was quantitative evidence that students in some of the collaborative classes did not perform as well as students in traditional classrooms on topic tests. Comments from students and teachers, however, suggested that for some students the collaborative learning model enabled them to learn more effectively, although other students were frustrated by the greater freedom and lack of direction. Future research could investigate the effectiveness of strategies to overcome this frustration and the relationship between different types of collaboration and developing mathematical understanding.

Foreign Language for Content: Aiming to Develop Lifelong Learning Dispositions

Dimova, Svetoslava 11 May 2012 (has links)
ABSTRACT FOREIGN LANGUAGE FOR CONTENT: AIMING TO DEVELOP LIFELONG LEARNING DISPOSITIONS by Svetoslava Dimova In the context of emphasis on English language, mathematics and science within the American educational system (No Child Left Behind, 2001), foreign language education appears to be increasingly dissociated from educational priorities. Ways to create relevant goals and optimize the effects of foreign language teaching emerge through the use of communication technologies and connections to academic content. This qualitative study explores the relationship between high school students’ skills in French as a foreign language (L2), their cognitive strategies during reading in L2 for academic content, and their motivation to read authentic French texts. The following questions guided the study: 1) How do students internalize the task of self-selected online reading in L2 for content understanding pertaining to their History of the Americas course? 2) What processes and skills do students evidence and draw upon to locate and read for information in L2?, and 3) What are the implications for building a theory of student motivations for extensive reading in L2 beyond the classroom context? The study was realized in the setting of an International Baccalaureate (IB) program, where 4 key informants were selected, and analysis was presented in the form of 4 case studies. Informants’ French language proficiency ranged from intermediate-mid to advanced levels (ACTFL Guidelines, 1999). Data collection occurred during 8 weeks and included three rounds of formal, phenomenological interviews, classroom observations, and students’ learning journals. Data were analyzed through the lens of Activity theory (Engeström, 1999) and motivation theory (Keller, 2008) in order to determine emerging themes. While both L2 skills and interest in historical content influenced the task completion, and informants used multiple strategies to search and read, internalization and motivation aspects related to acquiring content superseded those related to increasing language skills. Informants’ differences in attitudes toward the curriculum integrative task were additionally caused by their ideas of content appropriateness in a L2 course. Development of cultural awareness and critical thinking was also primarily shaped by interest in content. Findings from the analysis suggested further directions for L2 classroom instruction that could lead to developing students’ lifelong learning dispositions.

Telementoring Physics: University-Community After-school Collaborations and the Mediation of the Formal/ Informal Divide

Lecusay, Robert January 2013 (has links)
For several decades improvement of science education has been a major concern of policy makers concerned that the U.S. is a “nation at risk” owing to the dearth of students pursing careers in science. Recent policy proposals have argued that provision of broadband digital connectivity to organizations in the informal sector would increase the reach of the formal, academic sector to raise the overall level of science literacy in the country. This dissertation reports on a longitudinal study of a physics telementoring activity jointly run by a university-community collaborative at a community learning center. The activity implemented a digital infrastructure that exceeds the technical and social-institutional arrangements promoted by policy makers. In addition to broadband internet access (for tele-conferencing between students at the community center and physicists at a university), supplemented by digital software designed to promote physics education, the activity included the presence of a collaborating researcher/tutor at the community learning center to coordinate and document the instructional activities. The current research revealed a fundamental contradiction between the logic, goals, and practices of the physics instructors, and the corresponding logic, goals, and practices of the participants at the community learning center. This contradiction revolves around a contrast between the physicists’ formal, logocentric ways of understanding expressed in the ability to explain the scientific rules underlying physical phenomena and the informal, pragmatic orientation of the youth and adults at the learning center. The observations in this dissertation should remind techno-enthusiasts, especially in the arena of public education policy, that there are no turnkey solutions in “distance” science education. Technically “connecting” people is not equivalent to creating conditions that expand opportunities to learn and a functioning socio-technical system that supports learning. Secondly, for designers and practitioners of informal learning in community-university collaborative settings, it is critically important to understand distance learning activities as developing “cross-cultural, ” collaborative encounters, the results of which are more likely to be hybrids of different ways of learning and knowing than the conversion of informal learning into a tool for instruction that will allow youth to “think like physicists.”

Learning Together: Applying Socio-cultural Activity Theory to Collaborative Consultation in School-Based Occupational Therapy

VILLENEUVE, MICHELLE ANN 29 September 2011 (has links)
Socio-cultural activity theory (SCAT) was used to examine the nature of collaborative working in a case study of school-based occupational therapy (SBOT) in Ontario. Collaborative consultation has been widely adopted in SBOT practice. However, we know little about the impact of collaboration for students and lack understanding about how the organization of SBOT service contributes to collaborative working among educators and occupational therapists. Grounded in theoretical understanding about the distributed nature of group learning, SCAT was used as a conceptual and analytical tool in this study to describe SBOT collaborative consultation from multiple stakeholder perspectives. The research took place in two phases. Phase One involved case study research to describe SBOT for three students with disabilities from multiple stakeholder perspectives. Data were gathered using a combination of observation, document analysis, and interviews involving participants directly involved in the delivery of SBOT with each focal participant. SCAT provided a framework for describing the nature of joint effort. Dilemmas emerging from incongruence between elements in the activity system were identified and described. Common characteristics in two cases enabled cross-case analysis to also identify features of collaborative working that facilitated educational programming and outcomes for students with developmental disability. In Phase Two, program administrators participated alongside service recipients and service providers in a series of focused discussion workshops to reflect on case study findings and prioritize areas for program improvement. Developmental Work Research (Engeström, 2000) and Appreciative Inquiry (Cooperrider, Whitney, & Stavros, 2003) methods were used within a participatory action research approach to facilitate organizational learning among stakeholders. Engagement of stakeholders supported program administrators in critically examining decision-making for the delivery of SBOT service in the region studied. Combining practice-driven dilemmas with conceptual tools of analysis enabled a multiple-perspective understanding about the social, cultural, and historical work practices that have influenced collaborative interactions in SBOT practice and led to the development of principles for improving how work is shared. Program administrators used their shared understanding to propose a new model for delivering SBOT services. / Thesis (Ph.D, Education) -- Queen's University, 2011-09-28 21:31:58.308
