Nos últimos anos, um crescente número de trabalhos tem investigado o papel da argumentação em ambientes de ensino de ciências. Dentre os aspectos investigados estão: a identificação do espaço ocupado por atividades que fomentam a argumentação em aulas de ciências; a concepção e a avaliação de contextos didáticos que subsidiam o ensino e a aprendizagem da argumentação em aulas de ciências; a determinação da qualidade da argumentação dos estudantes em aulas de ciências e de fatores que conduzam à instauração do discurso argumentativo em ambientes de ensino de ciências. Neste trabalho temos como objetivo investigar o potencial do método de estudo de caso para promover a argumentação. A pesquisa foi realizada durante um semestre em um curso de graduação de química no Brasil. Após o recebimento de cada um dos casos, os estudantes trabalharam em grupos na resolução de perguntas, elaboradas com o intuito de guiá-los sobre questões relevantes relacionadas ao caso e vinculadas a conteúdos ministrados na disciplina na qual a pesquisa foi realizada (unidade curricular de "corrosão") e a aspectos ambientais e econômicos. O processo culminou nas apresentações orais dos grupos sobre as possíveis soluções para os casos e na realização de debates entre os grupos que haviam solucionado o mesmo caso. A coleta de dados envolveu as filmagens das apresentações orais das soluções de cada um dos casos e a posterior transcrição das falas dos alunos responsáveis pelas apresentações. A qualidade dos argumentos elaborados pelos estudantes foi analisada com base no Modelo de Toulmin e em ferramenta analítica...

Desde o início dos anos 80, diversas formas de organização e efetividade de atividades baseadas na Aprendizagem Colaborativa com Suporte Computacional (CSCL) têm sido discutidas. No entanto, o Brasil carece de estudos sobre tais temas, sobretudo no Ensino de Química. A colaboração efetiva em pequenos grupos confere à CSCL uma de suas principais características, o seu método de aprendizado único, bem sucedido e poderoso. A colaboração efetiva nos pequenos grupos incentiva os membros a lançar questionamentos, explicar e justificar suas opiniões, além de articular seu raciocínio, elaborar e refletir sobre seus conhecimentos, o que pode motivar e maximizar a aprendizagem. Essa dissertação apresenta e discute a implementação de atividades didáticas baseadas nos princípios da CSCL aplicadas em uma disciplina de comunicação científica oferecida a alunos de graduação em Química. Investigamos a dinâmica das interações dos alunos divididos em pequenos grupos, com foco na participação, habilidades interpessoais, habilidades de comunicação, processamento grupal e interdependência positiva, conforme o Modelo de Aprendizagem Colaborativa, desenvolvido por Soller et al. Analisamos ainda as percepções dos estudantes frente às atividades...

Vehicle collisions represent one of the largest anthropogenic causes of wildlife mortality. Herpetofauna are at risk for large population declines and potential extirpation as a result of a small percentage of total population mortality due to roads. Herpetofauna play an important role in wetland ecosystems and provide many ecosystem services. Ecopassages allow for the safe passage of animals under roads. The objective of this research is to identify the common elements of ecopassage developments and innovative practices that may be adopted for future application in Southern Ontario. In this paper four ecopassage case studies were used to ascertain the main features in ecopassage design and implementation. A qualitative analysis was done to highlight the major themes from each case. These themes were then compared with those present in the reference literature on ecopassages to determine their validity. In all of the case studies, the main ecopassage features were the identification of the species of importance, the identification of crossing ‘hot spots’, and the importance of fencing. The reference literature also cited the importance of mitigation and of installing ecopassages during initial road construction. Additionally, innovative approaches to ecopassage design were found in the Long Point Causeway and 1000 Islands Parkway cases. These include combining a change in driver behaviour with a change in animal behaviour and using the construction of an ecopassage as an opportunity to create a multi-use road thereby implementing multiple benefits into one development while offsetting the perceived cost and time of the project. Providing social benefits may also serve to bring the community together with their natural environment and will improve the public opinion surrounding ecopassage projects.; Undergraduate Honours Thesis Supervisor: Graham Whitelaw ENSC 501 April 2015; School of Environmental Studies

The case studies in this book provide useful information on the characteristics of students and the performance of various types of schools that benefit from public-private partnerships. While these case studies are empirically grounded, their results are not necessarily of universal application, because context also matters. The authors are careful to point out that while one of the case studies is based on an experiment, the other case studies use instruments or matching methods that have their limitations. Yet a key result from this work is that sound analyses of existing data are feasible and can yield useful conclusions about the contribution that private service providers can offer to educational development. These case studies will encourage more researchers to undertake similar work to demonstrate the many options that developing countries have to reach their education goals.

The objective of this volume is to assess the relationships between growth and poverty reduction on the basis of a number of case studies, all but one of which are based on recent household survey data. The first part of the volume presents data on Ghana and Senegal, two countries that have benefited from high levels of growth over the last dozen years. The analysis suggests that growth led to substantial reductions in the share of the population in poverty. Yet growth could not be said to be "pro-poor" because the gains in consumption for better off households were proportionately larger than the gains for poorer households. In the second part of the volume, case studies for Burkina Faso and Cape Verde are presented to solve the paradox of high growth without poverty reduction. It was initially believed in both countries that there had been no poverty reduction despite high growth during the 1990s. Yet a closer examination of the data suggests that this paradox was actually due to measurement errors: more careful work confirmed that poverty reduction was substantial. The third and last part of the volume presents case studies for Guinea-Bissau and Nigeria on the impediments to growth...

Collectively, the six country case studies provide an unusually rich source of material on the local dynamics of the aid business and the realities that countries face when they try to adopt CDF principles in earnest. In order to make this material more accessible (full case studies are over 70 pages), OED has summarized each study to about 15 pages and gathered all six summaries into this volume, which is intended to complement the main synthesis report for the CDF evaluation, Toward Country-Led Development: A Multi-Partner Evaluation of the Comprehensive Development Framework. This volume can also be used alone, to enrich the discussion of development assistance in a particular case study country or as a basis for comparing country experiences. Since the main purpose of the CDF evaluation was to look at what had happened since the CDF was launched, priority was given to interested countries where pilot implementation of the CDF was the most advanced (on the grounds that these countries would offer the greatest potential for learning). Consideration was also given to Regional balance. One non-CDF pilot country (Burkina Faso) was chosen as a control.

This book is about inventing successes and good practices of governments that are "closer to the people." Numerous examples throughout Latin America indicate-often despite macroeconomic instability, high inflation, and strong top-down regulation-that subnational actors have repeatedly achieved what their central counterparts preached: sound policymaking, better administration, better services, more participation, and sustained economic development. But what makes some governments change course and move toward innovation? What triggers experimentation and, eventually, turns ordinary practice into good practice? The book answers some of these questions. It goes beyond a mere documentation of good and best practice, which is increasingly provided through international networks and Internet sites. Instead, it seeks a better understanding of the origins and fates of such successes at the micro level. The case studies and analytical chapters seek to explain: How good practice is born at the local level; Where innovative ideas come from; How such ideas are introduced in a new context...

This study explores the international development community's understanding of poverty and illustrates how it is related to environmental degradation. the study relies on three sources: a comprehensive general literature review, a review of past donor interventions in Nigeria, and original empirical evidence. The linkages found between poverty and environmental degradation are based on 240 household surveys analyzed by income quintiles investigated at two sites in Nigeria: the Hadejia-Nguru Wetlands in the North and the Niger Delta in the South. Lessons relating "Causality and Linkages" (Chapter 2) explore various perceptions of how poverty "causes" environmental degradation, how environmental degradation "causes" poverty, or how other ofseting or reinforcing factors may influence the linkages between poverty and environmental quality. The empirical findings from the two study sites provide the primary basis for subsequent policy recommendations. Chapter 3 outlines the site selection process, summarizes the methods used...

This book synthesizes the findings from ten case studies that investigate whether, when, and how foreign aid affected economic policy in Africa, and reveals the range of African policy experience. Results varied enormously, for example, while Ghana and Uganda were successful reformers that grew rapidly reducing poverty, Cote d'Ivoire and Ethiopia have shown significant reform recently, but its sustainability remains to be seen, and, in other countries, policies changed little, or even worsened. Based on the World Bank's Country Policy and Institutional Assessment, the study relates foreign aid in the 1990s, to a measure of overall economic policy, a broad measure that covers macroeconomic management, as well as effectiveness of the public sector in providing essential services for growth, and poverty reduction. In assessing aid, and reform policy, the study subdivides these countries in three groups: the post-socialist reformers (Ethiopia, Mali and Tanzania); the mixed reformers (Cote d'Ivoire, Kenya and Zambia)...

Transport is not 'gender neutral'. Men and women hold different socio-economic roles and responsibilities that are associated with different patterns of transport access, needs, and use. Yet, there is often not much recorded evidence on the differences in gender travel needs between men and women, in urban areas in particular. Transport planning has not routinely addressed these differences and sex-disaggregated data on transport needs and patterns is very limited. The present regional report summarizes the findings and recommendations of four separate case studies on gender and transport conducted in Casablanca, Morocco, Sana'a and rural Yemen, and Nablus, Jenin, and Tulkarem in the northern part of the West Bank, during between September 2008 and September 2009. The main objective with summarizing the case studies into a regional report is to provide a regional overview relevant for a better understanding of how transport infrastructure and services are facilitating or constraining mobility by gender in the MENA region. In particular...

Purpose: The aim of this paper is to promote qualitative methodology within the scientific community of management. The specific objective is oriented to propose an empirical research process based on case study method. This is to ensure rigor in the empirical research process, that future research may follow a similar procedure to that is proposed. Design/methodology/approach: Following a qualitative methodological approach, we propose a research process that develops according to four phases, each with several stages. This study analyses the preparatory and field work phases and their stages. Findings: The paper shows the influence that case studies have on qualitative empirical research process in management. Originality/value:. Case study method assumes an important role within qualitative research by allowing for the study and analysis of certain types of phenomena that occur inside organisations, and in respect of which quantitative studies cannot provide an answer.

This study aims to assess the methodological rigor of case studies in management accounting published in Brazilian journals. The study is descriptive. The data were collected using documentary research and content analysis, and 180 papers published from 2008 to 2012 in accounting journals rated as A2, B1, and B2 that were classified as case studies were selected. Based on the literature, we established a set of 15 criteria that we expected to be identified (either explicitly or implicitly) in the case studies to classify those case studies as appropriate from the standpoint of methodological rigor. These criteria were partially met by the papers analyzed. The aspects less aligned with those proposed in the literature were the following: little emphasis on justifying the need to understand phenomena in context; lack of explanation of the reason for choosing the case study strategy; the predominant use of questions that do not enable deeper analysis; many studies based on only one source of evidence; little use of data and information triangulation; little emphasis on the data collection method; a high number of cases in which confusion between case study as a research strategy and as data collection method were detected; a low number of papers reporting the method of data analysis; few reports on a study's contributions; and a minority highlighting the issues requiring further research.

The aim of this study is to better understand the failure of young gifted athletes and the influence the parents / child relationships has on it. Three case studies are developed in order to put them back in their context. Interviews were carried out with players / parents / coaches. The players were specifically chosen as they had not reached elite level, despite very promising results in the junior leagues. The content analysis points out some favorable roles played by parents and other rather negative ones. It appears that their influence is closely linked to numerous interacting factors (parental values, motivations, parents / child, parents / coach relationships...). The case studies also clearly stress the importance of the choices made during the childs training, how they are linked to parental values, as well as the possible consequences of negative father / athlete relationships. Practical applications of this study should be taken into account to favor athletes carrer.

There has been the need to assess the effectiveness of the Hotel Operations course at Rochester Institute of Technology. The purpose of this report is to analyze the perceptions of these students and determine the effectiveness of the case method of instruction in the Hotel Operations course. A survey tool was used to obtain student responses. The tool was distributed to twenty six students; there was a response rate of 46 percent yielding a sample size of twelve. The responses were analyzed using SPSS software. Also a list of seven universities was compiled in order to get an idea how many other universities are utilizing a similar teaching format. The universities were chosen at random, however all either work closely with the industry or have a captive hotel. Only five universities responded, the University of New Hampshire was the only one that collaborated with the industry while conducting case studies. It was found that there was strong support for these case studies teaching method. Students feel that it was a valid technique that increases their theory retention. The majority of students do not believe that cases conducted in the Industry are more valuable than those conducted in the classroom. A manager can develop the most effective case studies from real situations. They should also be conducted in small groups followed by short presentations and class discussions. Also the manager that had to deal with the case in real life should be available to inform the students of the decisions that were made by management and why. Case studies should also utilize class time in order to obtain maximum participation.; Mentored by David Crumb and relates to the scholarship "Enterprise Learning" using the RIT Inn...

Three case studies were conducted to understand the factors that impact the demand for outsourced commercial printing by corporations. The cases included one university, one large retailer, and one food packager. For Rochester Institute of Technology (RIT), the purchase of a new offset press by the in-plant print shop resulted in a substantial increase in 2003 revenues, primarily through internal charge-backs. Many four-color jobs that formerly had been outsourced to external print services providers were able to be printed internally. One of the primary customers of the in-plant print shop is the Admissions Office. Their budget for printed recruitment materials has remained constant over the last 10 years because the growth in outreach to potential students has been through electronic media. Lately, internal printing by students and faculty is straining departmental budgets, and so many departments are considering document management strategies for the future. For Heluva Good Quality Foods, the change in primary and secondary packaging technologies in the last decade has decreased the need for printed labels applied to packages and increased the use of pre-printed flexible film. The locus of printing has shifted, in many cases, from the commercial printer to the packager/converter. Walgreens’ Printing and Mail Services unit sold its offset equipment in 2000 and purchased a digital color press (first an Indigo...

Structural failures occur from time to time, as seen from the recent (January 2006) rash of roof collapses in Germany, Poland, and Russia. However, many engineering and engineering technology students are not made aware of these failures in their analysis or design courses. In the author’s structural analysis and design courses, students are required to research specific structural failures, and to report on these failures, detailing the causes of failure - illustrated with pictures and free-body diagrams, and any lessons learned. Articles on several structural failures are posted regularly on the course website to draw the students’ attention to these failures and their consequences, as well as any lessons learnt; discussions of these failures on the course website discussion forum is also strongly encouraged. Our hypothesis is that studying specific structural failures has a positive impact on students’ learning experiences. To verify this hypothesis, an end-of-term student survey was conducted in two structural design courses where failure case studies were used. Analysis of the survey results indicates a positive impact of failure case studies on students’ educational experiences and awareness of ethical issues. The use of failure case studies in more engineering technology courses is also recommended.; Faculty Advisor: Abi Aghayere...

High-speed rail (HSR) has become a major contributor to the transportation sector with a strong push by the Obama Administration and the Department of Transportation to implement high-speed rail in the United States. High-speed rail is a costly transportation alternative that has the potential displace some car and airport travel while increase energy security and environmental sustainability. This thesis will examine the United States high-speed rail implementation strategy by comparing it to the implementation strategies of France, Japan, and Germany in a multiple case study under four main criteria of success: economic profitability, reliability, safety, and ridership. Analysis will conclude with lessons to be taken away from the case studies and applied to the United States strategy. It is important to understand that this project has not been established to create a comprehensive implementation plan for high-speed rail in the United States; rather, this project is intended to observe the depth and quality of the current United States implementation strategy and make additional recommendations by comparing it with France, Japan, and Germany.
