Em sua contribuição para a produção de conhecimentos aplicados à solução de problemas humanos, os analistas do comportamento vêm produzindo estudos sobre os processos básicos envolvidos na aquisição de desempenhos de leitura e escrita, e na descoberta de procedimentos de ensino para desenvolver estes repertórios. Alguns estudos têm obtido resultados positivos com a utilização de procedimentos que estabelecem o controle por unidades mínimas de leitura, sílabas, partindo do ensino de unidades macro, palavras. Resta, entretanto, pesquisar a possibilidade do ensino da leitura com procedimentos alternativos. Este estudo investiga a efetividade na instalação de desempenhos de leitura e escrita através de um programa que parte do ensino de leitura de unidades textuais mínimas para unidades maiores, utilizando técnicas operantes. Quatro dos seis participantes finalizaram o programa. Todos os participantes aprenderam a ler as palavras ensinadas. A emergência da leitura generalizada foi obtida prontamente em um participante, e com a extensão dos testes para os demais. Dois participantes aprenderam a construir palavras ensinadas e recombinadas ditadas. Os dados indicam o controle pelas unidades menores. Mais investigações do controle de estímulos sobre o comportamento de escrever palavras ditadas, uma relação importante de ser aprendida para atingir a alfabetização funcional, são necessárias.

As discussões sobre criatividade indicam uma dificuldade tanto na definição do que seria um padrão “original” ou “criativo” quanto de identificar que variáveis o controlariam. Dentre as interpretações deste fenômeno encontra-se a chamada “interconexão espontânea de repertórios”, quando dois ou mais repertórios diferentes, aprendidos em separado, podem se juntar em novas situações produzindo sequências originais de comportamento. A resolução de um problema de forma súbita através desta interconexão foi denominada de “Insight”. Um dos processos que participariam dessa interconexão seria a “Generalização Funcional”. O presente estudo replicou com algumas mudanças, utilizando três ratos (Rattus norvegicus) como sujeitos (S1, S2 e S3), o trabalho original de Epstein (1985b) e investigou o papel da “Generalização Funcional” na interconexão dos repertórios. Ao S1 e ao S2 foram ensinados separadamente três repertórios distintos. O S1 aprendeu a (1) empurrar um cubo de maneira direcionada, (2) a subir e se erguer sobre cubo e (3) a puxar uma corrente. O S2 aprendeu a (1) empurrar um cubo de maneira não direcionada, (2) a subir e se erguer sobre cubo e a (3) puxar uma corrente. O S3 aprendeu apenas a (1) subir e se erguer sobre cubo e (2) a puxar uma corrente. Após o treino foram colocados numa situaçãoproblema que exigiria a interconexão das habilidades aprendidas para que a resolução ocorresse. O S1 e o S2 resolveram o problema de maneiras distintas: o S1 resolveu de forma aleatória e o S2 resolveu após um treino adicional de subir e puxar a corrente que estabeleceu elos importantes para a resolução. O S3 não resolveu o problema. Os dados indicaram que a generalização funcional poderia ser explicada como generalização simples e que esta não seria um requisito fundamental para a resolução súbita do problema.

This paper presents a proposal for the teaching of cataloguing, emphasizing the problem-solving methodology. The proposal was designed for the distance-based continuing education of the professional cataloguer. It takes into account the challenges inherent to the development of interactive and inter-disciplinary tasks, as well as the development of directed self-education and critical consciousness of that professional, inasmuch as he becomes an active subject, manager of his/her own education.

When I set out to attend degree in mathematics was because I believed that mathematics could be taught to students in a way closer to their daily lives, thereby making it a more attractive school discipline, gradually, eliminating its reputation of a difficult school subject. Then, during my observations in supervised, I realized that one of the greatest difficulties in mathematics was related with geometry, in which the concepts of area and perimeter were often confused. Using the methodological tool of problem solving, something to bring the concept to be developed and the cultural context in which the student is in, I developed some educational activities in which, using concrete materials, students were encouraged to construct their own knowledge about the concepts of area and perimeter. Moreover, such activities were designed to place the student as the center of attention in the classroom. The main objective of this work is to encourage and observe how this methodology, based on the solving problem process, can be used within the classroom, to better understand the concepts to be taught, always looking for improvement of the student learning

Since the 1980s, problem solving has been recommended by international curriculum proposals for the teaching of mathematics. In Brazil, with the publication of the National Curriculum Guidelines in 1997, this trend was reinforced and became the central activity of the classroom. Troubleshooting is seen as an asset in the learning process of the student, providing a context for learning concepts, mathematical methods and attitudes. However, this methodological approach requires deeper research, especially for new teaches. This work aims at a further study in this subject and in the experiences with problem solving in the classroom of High School students. The ground basis for this was the Mathematical Transalpine Rally, a competition between classrooms that seeks to facilitate the problem solving within mathematics teaching, and through an autonomous and creative work, performed collectively. The results of this experience, as well as the contribuition for the student’s education are presented

The mathematical problem solving is very important in the student's school career, leading him to develop his creativity and self-confidence. The way the teacher explains specific content may interfere in the student learning. Some researches show that the teacher trust and his problem solving rapport lead to a more satisfying job. This research focused on students of the course PARFOR at UNESP Bauru. This work was performed in order to investigate the affinity, trust and attitudes toward mathematical problem solving, the performance from who have positive and negative attitudes and the results that may be generated during class

The financial health of a family is one of the main generators of quality of life, and this is only possible through financial planning, which is nothing more than save and analyze before contracting debts. To do this, students must have notion of financial mathematics, especially of that used by the banks on overdraft interest, in investments and in the short-term and longterm loans, that is, compound interest, equivalent rates, depreciation and others. Starting from the knowledge of arithmetic and geometric progressions and, based on real situations which allow the application of the content learned, one intends to develop activities applied to high education. To start from real situations is one of the main lines of thought of the Problem Solving Methodology, in which the student is the active agent in the construction of his or her knowledge. As the National Curricular Parameters point out, the practice in the use of computers is essential for gaining a job. Therefore, this project proposes an activity where knowledge of Financial Mathematics can to be practiced, associated with the use of Microsoft Excel® spreadsheet

The competitiveness in the industrial sector is increasingly fierce. In this context, the quality of maintenance is often neglected due to the sense of urgency that arises in these companies. Thus, it becomes increasingly necessary to use tools of Reliability Centered Maintenance to assist in managing maintenance effectively and efficiently, and directing resources .This study aims to evaluate the use of the fault tree to identify critical paths in the maintenance sector in an industry. The proposal is uses the tools of Reliability Centered Maintenance (MCC) for the collection, disposal and prioritizing causes problems in the transport industry. The study has its focus on the theoretical foundation of problem solving methods and techniques to identify the root causes, using the fault tree
