Such a choice is justified by the weight and responsibility of these groups to complete this phase of education. These classes are evaluated internally as a form of school approval, and externally as a statistic of the government system for the presentation of educational indexes. The bibliographical and field research aim to observe and validate the report between the applied methodologies: traditional and problem solving. Make a comparison between the content-transmitting teacher or mediating teacher and the student receiving or interpreting questions before resolving them. The methodological application is done in two groups of students in a same period of the academic year in the theme of Analytical Geometry, the results are presented in a tabulated evaluation and described in this dissertation, followed by a questionnaire evaluation applied to give consistency to the research with the reports of the students. These results lead to a final analysis of methodological proposals of mathematics teaching. Finally, it is proposed as methodology the hybrid study, it is possible to insert and compare with proposals of other methods and new studies. The results show a tendency to use the alternative methodology through data and reports collected. / Na proposta de análise metodológica do ensino de matemática no nível básico, desenvolve-se um trabalho no Ensino Médio, com a terceira série. Justifica-se tal escolha ao peso e responsabilidade que essas turmas têm em concluir essa fase do ensino. Essas turmas são avaliadas internamente como forma de aprovação escolar, e externamente como estatística do sistema governamental de apresentação de índices educacionais. A pesquisa bibliográfica e de campo visam observar e validar o relato entre as metodologias aplicadas: tradicional e resoluções de problemas. Faz uma comparação entre o docente transmissor de conteúdos ou professor mediador e do discente receptor ou intérprete de questões antes de resolvê-las. A aplicação metodológica é feita em dois grupos de alunos em um mesmo período do ano letivo no tema de Geometria Analítica, os resultados são apresentados em uma avaliação tabulada e descrita nessa dissertação, seguido de uma avaliação de questionário aplicado para dar consistência à pesquisa com os relatos dos discentes. Tais resultados levam a uma análise final de propostas metodológicas do ensino da matemática. Finalmente propõe-se como metodologia o estudo híbrido, cria-se possibilidade de inserções e comparações com propostas de outros métodos e novos estudos. Os resultados mostram uma tendência a utilização da metodologia alternativa através de dados e relatos colhidos.

Requirements are features or attributes which we discover at the initial stage of building a product. Requirements describe the system functionality that satisfies customer needs. An incomplete and inconsistent requirement of the project leads to exceeding cost or devastating the project. So there should be a process for obtaining sufficient, accurate and refining requirements such a process is known as requirement elicitation. Software requirement elicitation process is regarded as one of the most important parts of software development. During this stage it is decided precisely what should be built. There are many requirements elicitation techniques however selecting the appropriate technique according to the nature of the project is important for the successful development of the project. Traditional software development and agile approaches to requirements elicitation are suitable in their own context. With agile approaches a high-level, low formal form of requirement specification is produced and the team is fully prepared to respond unavoidable changes in these requirements. On the other hand in traditional approach project could be done more satisfactory with a plan driven well documented specification. Agile processes introduced their most broadly applicable technique with user stories to express the requirements of the project. A user story is a simple and short written description of desired functionality from the perspective of user or owner. User stories play an effective role on all time constrained projects and a good way to introducing a bit of agility to the projects. Personas can be used to fill the gap of user stories.

There are several critical success factors suggested for why agile software development projects succeed, including organisational and process factors. Although there are an increasing number of identified critical success factors, IT professionals lack the modelling techniques and the theoretical framework to help them meaningfully understand their influences. To solve this problem, this study developed a model by employing the following theories: Theory of Reasoned Action (TRA), Theory of Planned Behaviour (TPB), and Unified Theory of Acceptance and Use of Technology (UTAUT) to create a fit model for agile software development projects. The research sought to answer the question: What are the critical success factors that influence the success of agile software development projects? The literature review considers the continued failure of agile and traditional software development projects which have led to the consideration of, and dispute over, critical success factors — the aspects most vital to a methodology’s success. Though TRA, TPB and UTAUT have previously been applied to agile methodologies, empirical models have not been completely integrated to develop a fit model. This research sought to fill this gap. Data was collected in South Africa through a web-based survey using structured questionnaires and an interview guide. Face-to-face interviews were done to identify the critical success factors in agile projects. The data was captured and analysed for descriptive statistics, convergent and discriminant validity, composite and internal reliability, and correlation in order to inform the structural equation modelling (SEM). SEM was used to test the research model and hypotheses to answer the research questions. The results informed development of a comprehensive model that could provide guidelines to the agile community. The study contributes towards understanding the critical success factors for agile projects. It examined direct, indirect and moderating effects, and the findings contribute towards developing a framework to be used by agile professionals. These key result shows that organisational factors have a great influence on performance expectancy characteristics. To ensure success of agile projects, managers are advised to focus on the effect of the organisation’s environment, culture and policies on performance and effort expectancy. / School of Computing / Ph.

Although there is a growing influence of psychology and human resources in modern management, this area is being often neglected in theory and particularly in praxis of project management. This area offers a big potential for improvement of performance of project teams and increase of teamwork efficiency. Therefore this thesis is focused on human factor in project management and the opportunity for using psychology, especially the theory of motivation and teamwork. There were set more main goals of thesis they can be split in two groups. In the first group there are research goals aimed on teamwork in project teams managed by agile or traditional methods, establishment of project teams, characteristics of projects suitable for agile approach and implementation of agile methods in a company. The proposal of solution of identified problem areas belongs to the second group of goals. According to the research results agile project teams are closer to psychological concept of team, whilst traditional project teams are closer to work groups. Therefore agile project teams have better potential for being more efficient and performing higher than the project teams managed by traditional methods. Another finding in this thesis is regarding setting up the project teams and their daily work. Although agile methods seem to be more efficient from the teamwork perspective, they don't offer general solution for all problems in project management and their usage is not necessary suitable for all kinds of projects and company environment. That's why the characteristics of appropriate projects for being managed by agile methods were also investigated. Successful implementation and application of agile methods is strongly influenced by company environment and other factors that were identified in theoretical part of the thesis and subsequently verified by the research. The thesis brings a lot of verified information regarding work in project teams and emphasizes the significance of management, motivation and development of project teams. For identified problem areas with significant potential for improvement were prepared two solution proposals included in final parts of the thesis. The first solution is a model for implementation of project methodology in a company; the second one is a model aimed on project team performance increase. Both proposed solutions offers specific tools and techniques ready for application in company environment.
