Este estudo tem a intenção de descrever, entender e explicar processo deaprendizagem de uma turma de 4º Ano do Ensino Fundamental I, com proposta de utilizar objetos concretos na aprendizagem matemática, no qual procurou desvendar à luz da concepção de inovação de que maneira esses objetos constituem uma instigação à Inovação pedagógica. Mediante aos padrões culturais da turma pretende-se conhecer e verificar o impacto desta proposta, no cotidiano dos alunos, por meiodos saberes de cada um envolvidos. Uma vez que, é visível a complexidade e a desmotivação que o aluno do ensino fundamental I apresenta com a Matemática. A necessidade de tornar a aula mais interessante e motivadora é uma inquietação constante do professor, no qual a dissertação investiga a importância dos objetos concretos, sua funcionalidade e aplicabilidade, de modo que possa facilitar a aprendizagem, bem como, proporcionar subsídios para que o aluno desenvolva estratégias significativas e inovadoras, melhorando assim, a qualidade do aprendizado matemático e seja capaz de criar situações que promovam a curiosidade, a instigação e a busca de resoluções, possibilitando no seu cotidiano empregar o conhecimento científico. O estudo tem como alusão a construção do pensamento crítico dos alunos a partir das concepções trabalhadas na sala de aula. Nessa acepção, a presente investigação insere-se numa abordagem qualitativa, de caráter etnográfico. Desenvolve-se por intermédio da investigadora com a turma, com vista à descrição da realidade estudada, seus padrões culturais e significativos, visando a compreensão do ambiente analisado. Através dos recursos como a observação participante, a entrevista e os documentos foi possível o recolhimento de dados durante a estadia no contexto do estudo. As conclusões desta investigação apontam de certa forma para a interatividade e a compreensão de certos conceitos matemáticos, mas não induz a autonomia dos alunos, o seu projeto de vida, ou seja, não perfigura um desafio à Inovação Pedagógica.

Dopamine (DA) is known to regulate both sleep and memory formations, while sleep plays a critical role in the consolidation of different types of memories. We believe that pharmacological manipulation of dopaminergic pathways might disrupt the sleep-wake cycle, leading to mnemonic deficits, which can be observed in both behavioral and molecular levels. Therefore, here we investigated how systemic injections of haloperidol (0.3 mg/kg), immediately after training in dark and light periods, affects learning assessed in the novel object preference test (NOPT) in mice. We also investigated the hippocampal levels of the plasticity-related proteins Zif-268, brain-derived neurotrophic factor (BDNF) and phosphorylated Ca2+/calmodulin-dependent protein kinases II (CaMKII-P) in non-exposed (naïve), vehicle-injected controls and haloperidol-treated mice at 3, 6 and 12 hours after training in the light period. Haloperidol administration during the light period led to a subsequent impairment in the NOPT. In contrast, preference was not observed during the dark period neither in mice injected with haloperidol, nor in vehicle-injected animals. A partial increase of CaMKII-P in the hippocampal field CA3 of vehicle-injected mice was detected at 3h. Haloperidol-treated mice showed a significant decrease in the dentate gyrus of CaMKII-P levels at 3, 6 and 12h; of Zif-268 levels at 6h, and of BDNF levels at 12h after training. Since the mnemonic effects of haloperidol were only observed in the light period when animals tend to sleep, we suggest that these effects are related to REM sleep disruption after haloperidol injection

This study investigates the development of Learning Objects for the literacy of children. It aims to know based in the notion of literacy teachers the main factors of academic failure in literacy and researching in Brazil, as well as identify relevant activities in the literacy process of children to support the creation of a set of Learning Objects. Refers to an exploratory research, which is configured as a qualitative nature case study, inspired in part in an action-research described by Thiollent (2003), conducted with ten early grades elementary school teachers of a public municipal school in Parnamirim / RN. As methodological options for data collection uses questionnaires and focuses on the group of teachers, analyzing the data, referring back to the ideas by Szymanski (2001; 2008) and content analysis, guided by Bardin (2002). The development of Learning Objects, follows the steps of development suggested by Garrett (2000). Rules in its multidisciplinary theoretical reference and promotes a conceptual dialogue on: Literacy; Literacy School Failure; Pedagogical Practice in Literacy; Thoughts and Language; Multimedia and Hypermedia; Learning Objects. Perceives that the act of education in literacy as an act of love, courage and social interaction between individuals - educator and pupil, so there is ownership of the object of knowledge in the relations with the world and with the experience, through a pedagogical practice that assumes all different knowledges, the moral political ideal, the mindsets of the students, and can make use of teaching materials that supports the learning process and are consistent with the educational objectives (FREIRE, 1998; FREINET, 1976; VYGOTSKY, 1998; FERREIRO AND TEBEROSKY, 1985; JONASSEN, 2000; WILEY, 2001). Figures out, through the teachers' opinions, five reasons for school failure in literacy, three inside the school environment: teacher; academic assistant and principal; student, and two outside the school environment: parents/family; government and public management. Presents a set of Learning Objects, based on the constructivist thought, developed from the identification of activities considered relevant by teachers in literacy's teaching and learning process. Suggests the use of Learning Objects as pedagogical practice in literacy as a digital resource that supports learning and can trigger important cognitive processes for the acquisition of reading and writing skills in the school environment

This paper discusses aspects related to the mathematical language and its understanding, in particular, by students of final years of elementary school. Accordingly, we aimed to develop a proposal for teaching, substantiated by mathematical modeling activities and reading, which takes advantage of the student of elementary school a better understanding of mathematical language for the content of proportion. We also aim to build / propose parameters for the assessment of reading proficiency of the language of the student in analyzing and modeling process, its ability to develop/improve/enhance this proficiency. For this purpose, we develop a qualitative research, with procedures for an action research whose analysis of the data is configured as Content Analysis. We refer to epistemological and didactic, in the studies: Piaget (1975, 1990), Vygotsky (1991, 2001), Bakhtin (2006), Freire (1974, 1994), Bicudo and Garnica (2006), Smole and Diniz (2001), Barbosa (2001), Burak (1992), Biembengut (2004), Bassanezi (2002), Carrasco (2006), Becker (2010), Zuin and Reyes (2010), among others. We understand that to acquire new knowledge one must learn to read and reading to learn it, this process is essential for the development of reading proficiency of a person. Modeling, in turn, is a process which enables contact with different forms of reading providing elements favorable to the development here mentioned. The evaluation parameters we use to analyze the level of reading proficiency of mathematical language proved to be effective and therefore a valuable tool that allows the teacher an efficient evaluation and whose results can guide you better in the planning and execution of their practice

Neste artigo quero apontar para a possibilidade de uma ontologia da matemática que, mesmo mantendo alguns pontos em comum com o platonismo e com o construtivismo, desliga-se destes em outros pontos essenciais. Por objeto matemático entendo o foco referencial do discurso matemático, ou seja, aquilo sobre o qual a matemática fala. Entendo que a existência destes objetos é meramente intencional, presuntiva, mas, simultaneamente, objetiva, no sentido de ser uma existência comunalizada, compartilhada por todos aqueles engajados no fazer matemático. A existência objetiva das entidades matemáticas não está, entretanto, garantida de uma vez por todas, mas apenas enquanto o discurso matemático for consistente. Este é o espírito do critério de existência objetiva enunciado que, acredito, deve sustentar uma ontologia matemática sem o pressuposto da existência independente de um domínio de objetos matemáticos, sem o empobrecimento que lhe impõem as diferentes versões construtivistas e sem a aniquilação que lhe infringe o formalismo sem objetos.

Exploratory behavior is done by animals to increase their interaction to the environment after be stimulated by curiosity, when animal feels that is in a secured place. The objective of this study was to evaluate exploratory behavior of foals front of introduction of new objects in their environment. Four foals and mares were observed in seven day sections of 60 minutes each one, always with a new object. No differences were verified about frequencies of looking, going to or touching into foals and mares. Total time of touching was 45,6 minutes, divided in 64 touches, mainly in first 20 minutes of each observation. However there is no statistical difference into solitary or impaired approaches and in impaired approaches there is no differences into foals or mares initiatives, foals done more solitary approaches than mares. Four animals touched the objects in first place, suggesting predisposition to this position based in individual differences. So, we concluded that new objects can stimulate similarly foals and mares to exhibit exploratory behavior, but foals show more manipulation activity, suggesting that are more curious than mares and predisposition to touch objects first depends of individual differences.
