A origem de comportamentos criativos é em grande medida pouco conhecida cientificamente. Aparentemente, trata-se de um fenômeno multifacetado que comporta muitos processos distintos. Um desses processos seria a resolução de problemas conhecida como “insight”. Tal processo pode ser explicado como resultado de uma interconexão espontânea de repertórios comportamentais previamente aprendidos. A presente pesquisa teve por objetivo produzir diferentes desempenhos de “insight”, em macacos-prego (Cebus spp.) dando-lhes diferentes histórias de treino. Em especial, pretendeu-se testar o papel da quantidade de treino de cada repertório pré-requisito. Seis sujeitos foram divididos em dois grupos de três sujeitos cada. As habilidades pré-requisitos para a resolução da tarefa foram: 1) juntar objetos (“encaixar”); e, 2) puxar uma caixa contendo alimento usando uma vareta (“pescar”). Todos os sujeitos passaram pelo treino das duas habilidades, sendo que um grupo (GS) passou por um treino simétrico (mesma quantidade de sessões) entre as duas habilidades, com critérios de aprendizagem elevados para ambas. O outro grupo (GA) passou por um treino assimétrico, no qual uma habilidade, a de encaixe, foi treinada em poucas sessões e com um baixo critério de aprendizagem. Neste grupo a habilidade de pescar teve um treino extenso, com um número de sessões de treino pelo menos duas vezes maior do que o treino da habilidade de encaixe, e um critério elevado de aprendizagem. Ao final, todos os sujeitos foram colocados frente a uma situação problema: uma caixa contendo comida fora de seu alcance, e duas ferramentas disponíveis, das quais nenhuma sozinha alcançava a caixa. Nesta situação a solução dependia da recombinação dos dois repertórios ensinados separadamente, encaixar e pescar. Apenas o terceiro participante do grupo assimétrico não resolveu a tarefa. Todos os demais participantes resolveram a tarefa consistentemente, apresentando topografias de resolução do problema de acordo com o seu treino, apontando que variáveis de quantidade de treino influenciam na forma e eficácia da resolução da tarefa.

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

Dissatisfaction with certain aspects of the educational processes of the traditional teaching has always existed, and new teaching methods have been routinely studied. The experimental investigative activity is one of those alternative practices. In this type of activity the experimentation is inserted with an investigative approach, in which the student must build the concept, with proposals that represent solutions to the excited problems. In the teaching of chemistry, specifically, the need and importance of experimentation is evident, beyond motivate students, aid in the understanding of chemical concepts relating them to reality. Realizing the contributions of this methodology for teaching and learning, through this research was conducted to understand the difficulties encountered by teachers for planning and implementation of these activities in the teaching of chemistry and therefore the reasons for the dominance of traditional teaching method. The subjects were undergraduate students of chemistry course that developed and implemented differentiated learning activities for teaching and teachers who accompanied the high school students who participated in the university extension project Inclusion Science and University students and teachers from public: Teaching and Learning Chemistry focuses on research and practice”. Through the data it was possible to identify some factors that affect and hinder the implementation of experimental activities in general, not only the investigative. However, despite the difficulties experienced by undergraduates, the majority considered the activity as an alternative teaching method interesting and innovative, able to produce interest, motivation and participation of students with subsequent learning. As well as the teachers, what with all the difficulties that they had declared facing when applying experimental activities, they admitted the pedagogical...

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

Falls among older people is a major clinical problem due to its high incidence, with consequent implications for the health and care costs. Elderly patients with dementia of Alzheimer type (AD) are more susceptible to falls due to the impairment of executive functions and gait, with the risk of falls 3 times higher than non-demented elderly. This study used a longitudinal design and aimed to analyze the effects of a regular and systematized physical activity program on the frequency of falls in patients with AD. Additionally, we aimed to correlate the frequency of falls with the executive functions and equilibrium, after and before the physical activity program. The study included 21 patients with clinical diagnosis of AD, divided into two groups: control group (CG), composed of 11 subjects not engaged in any systematized physical activity and training group (TG): 10 seniors who participated in the Cinesioterapia Functional and Cognitive in Elderly with Alzheimer's disease program (PRO-CDA). The physical activity program lasted four months, with weekly frequency of three times, with each session lasting 60 minutes. Were administered the Mini-Mental State Examination (MMSE) to assess cognitive functioning and global score of the Clinical Dementia Rating (CDR) to classify the severity of dementia. For the evaluation of executive functions were used the Clock Drawing Test (TDR) and Frontal Assessment Battery (FAB). In addition, we used the Functional Balance Scale, Berg test (EEFB) and Timed Up-and-Go (TUG) to assess the equilibrium and risk of falls. Falls were recorded by means of a questionnaire, which included the number of falls in the last four months. Analyzing the results, it was observed that TG obtained significant improvements in equilibrium and in executive functions, highlighting the beneficial effects of physical activity in these variables...
