Literatura de monteiro lobato no ensino de ciências

Advocating education as a humanizing task, the humanizing function of literature and the importance of scientific education, this paper proposes linking Science and Literature in Science Teaching using two specific books of Monteiro Lobato in the final series of elementary school level. Adopting the action research methodology, an interdisciplinary approach, we used the books A Reforma da Natureza and Serões de Dona Benta in two classes (8th and 9th) at Escola Estadual Professor José Mamede, located in the town of Tibau do Sul, Rio Grande do Norte. The readings were performed in Portuguese Language s course and the scientific content were discussed in Science´s classrooms. The book A Reforma da Natureza permitted to approach issues related to the environment, while the use of Serões de Dona Benta showed particularly its effectiveness in questioning the concepts of matter, mass, weight and some questions about the Nature of Science (NOS). In general, the analysis of results shows that the readings of these two books permitted interaction and dialogicity in the classroom, as well as indicates the potential of these books in contextualing and questioning the scientific content contained in it. We advise, however, the need for the science teacher be aware of the conceptual mistakes present in literary works, avoiding erroneous learning and reinforcement of alternative conceptions

Efeitos de um programa de intervenção precoce baseado no modelo mais que palavras - HANEN, para crianças menores de três anos com risco de autismo

In the last decades, studies on early intervention involving children with autism have suggested that there is no single intervention model capable of addressing the needs of all individuals in the spectrum. The role of parents as active intervention agents is, however, highly recommended. The More Than Words-HANEN Program has been specifically created for parents of children, under five years of age, who are in the autism spectrum. This intervention aims at improving the social competence and language comprehension of the child, as well as their parents empowerment. Until now only three studies have been performed in order to evaluate the effectiveness of the HMTW program. The purpose of this investigation is to evaluate the effects of an early intervention program inspired on HMTW model on the level of caregiver responsiveness and child communication skills. The present study adds to the existing research literature on family-centered early intervention that uses a developmental paradigm. A two year boy in risk for autism, his mother and nanny took part in this investigation, which was carried out in the child´s home in Mossoró, Rio Grande do Norte. The caretakers were given one fifty-two hours of training, divided into thirteen weekly meetings. A quasi-experimental A-B-C design (baselineintervention- follow-up) showed improvement in the caretakers level of responsiveness and meaningful social-communicative gains in the child´s response

Análise dos efeitos de um plano educacional individualizado no desenvolvimento acadêmico e funcional de um aluno com transtorno do espectro do autismo

Given the paradigm of inclusive education, the presence of students with autism spectrum disorder in regular schools has become more significant in recent years. Studies have revealed, however, deficits in academic participation of these students in these settings. Among the factors contributing to this phenomenon include poor teacher training and the lack of strategies to promote curriculum access. The aim of this study was to develop an instrument that would promote academic inclusion of a student with autism through procedures that could simultaneously empower the teacher. In this perspective, the study aimed to analyze the effects of an Individualized Educational Plan (IEP), developed collaboratively with teachers, on the academic and functional development of a student with autism in an early childhood education setting. Data were collected in a private school located in the city of Natal in Rio Grande do Norte, in the course of the academic year 2012. In addition to the student with autism, one teacher, a specialized educator, and four teacher aides participated in the study. The research used a single subject quasi-experimental design (AB) as well as qualitative methods of data analysis. The study was conducted in three phases: characterization, baseline and intervention. The first comprised interviews with the child´s parents and teachers, as well as the identification of two routines focus of intervention. In the second phase, the amount of time the student spent engaged in the selected routines during baseline was analyzed. In the third phase, the researcher prepared, collaboratively with the teachers, an individualized educational plan (IEP) for the student. Finally, the IEP was implemented by the teachers. The results indicated qualitative and quantitative changes in student´s participation in academic and functional tasks after the intervention program

Práticas populares de cuidado à criança: o saber/fazer de cuidadoras

Popular practices correspond to the resources used by households, lay people and popular therapists, whose perception of knowledge is constructed in the everyday. In this context, the sick child can become vulnerable to be dependent on a family caregiver, who often decide to employ popular practices. Thus, the child care should be shared between carer and health professional. However, they know little about the resources that the family uses to detect a grievance in infant. Therefore, the present research aimed to analyse the use of popular practices by caregivers of children with zero to five years old. We conducted an exploratory and descriptive study with a qualitative approach, together with 15 caregivers of children who were treated at the Joint Unit Felipe Shrimp, located in Natal, Rio Grande do Norte, Brazil. To select the participants, they should be age and above 18 years; be caregivers of children up to five years of age; and reside in the area ascribed the Joint Unit Felipe Shrimp. The data collection took place between September and October 2013, through in depth interview. This step was preceded by the approval of the Health Department of the city of Natal; the direction of the Joint Unit Felipe Shrimp; as well as, the Committee on Ethics in Research from the Federal University of Rio Grande do Norte with Certificate of Presentation and Consideration Ethics, No 15467013.8.0000.5537. Furthermore, the interviewees formally authorized their participation in the research by signing the consent form. The data were treated according to the technique of content analysis in the form of thematic analysis according to Bardin. This process, four categories emerged: "Types of popular practices used in the care of the child"; "Source of information of popular practices"; "Results obtained with popular practices"; "Factors that hinder the adoption of common practices." The results showed the use of popular practices by caregivers in the case of illness to children such as the homemade preparations with medicinal plants and folk healers. The family environment was referenced as the main learning space and spread of popular practices, which are influenced by cultural relations present in this context. As to the results obtained with popular features, the caregivers said to be satisfactory, and this triggers a feeling of confidence and acceptability of such measures. It is concluded that the use of popular practices in child care persists in everyday most of the participants, despite the hegemony of allopathic therapy. The caregivers stated that such practices are effective and easy to obtain, being secured in context by popular culture. In addition, health professionals, especially nurses, were seldom mentioned by the caregivers as to the information concerning popular resources used by them, which suggests the weakness in dialogic process of negotiating practices between both of them

Estudo do comportamento no estado fresco e endurecido do concreto com incorporação de resíduo de corte de botão

This works aims at investigating the effects of adding waste from RCBP-polyester button manufacturing to Portland cement concrete, particularly regarding its consistency and mechanic strength. The RCBP used came from a button factory located in Parnamirim, RN, Brazil. The waste was added to the concrete on different ratios: 5 %, 10 %, 15 % and 20 % of the total cement mass. A sample of concrete without the RCBP was used as reference, 1:1,33:2,45:0,50. For the mechanic strength test four samples were tested with different ages (3, 7 and 28 days old) and mixtures. Furthermore, a Slump Test was also conducted in order to verify the concrete s consistency. A tendency to a reduction in the compression resistance was noticed for all samples. For the samples with 5 % and 10 %, there was also an increase in the traction resistance during inflexion, regarding the reference concrete. In the microstructural analysis, the RBCP was observed to show an irregular and porous surface, thus explaining the consistency decrease

Proposta de um modelo de medição e avaliação de desempenho como ferramenta de gest ão - um estudo de caso num órgão público

The public sector performance has received much attention in the literature and due to that the purpose of this work is to develop a proposal for a model of performance measurement for a higher education institution unit. First, we performed a theoretical research on public organizations and private institutions of higher education, followed by a literature review on performance measurement and evaluation. This review presents some performance models that are quite frequent in the literature: Total Quality Management (Total Quality Management) - TQM and the PDCA cycle, SMART System, Balanced Scorecard and Môdef Ouanturn. In order to verify the possibility of implementing a performance measurement model for Higher Education Institutions, it was conducted a case study in a support unit of a University, located in the city of Natal, RN, Brazil. The study attempted to identify the key processes of the unit and proposed by the use of Quantum model in order to improve the management and operation of the same. The work aims to contribute to the advancement of knowledge in measurement and performance evaluation in higher education institutions that where still lacks scientific production of this subject compared to other areas. This study also identifies better practices and opportunities for improvement in processes to determine the expected performance indicators to aid a decision-making unit.

Desenvolvimento de metodologia para avaliação de desempenho ambiental em edifícios adaptada à realidade do Nordeste brasileiro

This research refers to the production of green buildings, defined, mainly, based on the use of sources of alternative energies, smaller emission of pollutant, use of recyclable materials, systems of recycling of the waters, maximization of the natural illumination, preservation of green areas or native, and appropriate quality of the internal air. From the conception of those buildings, it appears the needs of evaluating them, creating the methodologies for the evaluation of environmental performance of buildings. In that way, this work can be divided in two moments: the first one when it identifies the methodologies for the evaluation of environmental performance for buildings existents in the literature, defining their categories, criteria and sub-criteria to be appropriate to the reality of the Brazilian Northeast; and the second one when starting from the analysis of the systems of existent evaluation. It defines a methodological base and it generates a new evaluation system, denominated MEDACNE (Methodology of Evaluation of Environmental Acting for Construction in the Northeast). In that moment, the process of framing of the section of the building site is verified under the maintainable optics, stimulated mainly by the pressures of the society - conferences, protocols and agreements. Finally, the proposed methodology was applied in a case study, a residential building, called Maria José Gurgel , located in Natal-RN, Brazil, for its validation. This methodological proposition should increase the patterns environmental places for the production of new buildings, and it will be a reference guide for architects, engineers and planners to develop their constructions considering the criteria of the sustainability. This study made use of bibliographical research in books and specialized magazines and the analysis of the data was realized in an interpretative way

RoboEduc: uma metodologia de aprendizado com robótica educacional

In this work, we propose a methodology for teaching robotics in elementary schools, based on the socio-historical Vygotsky theory. This methodology in conjunction with the Lego Mindstoms kit (R) and an educational software (an interface for control and programming of prototypes) are part of an educational robotics system named RoboEduc. For the practical development of this work, we have used the action-research strategy, being realized robotics activities with participation of children with age between 8 and 10 years, students of the elementary school level of Municipal School Ascendino de Almeida. This school is located at the city zone of Pitimbu, at the periphery of Natal, in Rio Grande do Norte state. The activities have focused on understanding the construction of robotic prototypes, their programming and control. At constructing prototypes, children develop zone of proximal development (ZPDs) that are learning spaces that, when well used, allow the construction not only of scientific concepts by the individuals but also of abilities and capabilities that are important for the social and cultural interactiond of each one and of the group. With the development of these practical workshops, it was possible to analyse the use of the Robot as the mediator element of the teaching-learning process and the contributions that the use of robotics may bring to teaching since elementary levels

RoboEduc: especificação de um software educacional para ensino da robótica às crianças como uma ferramenta de inclusão digital

Because of social exclusion in Brazil and having as focus the digital inclusion, was started in Federal University of Rio Grande do Norte a project that could talk, at the same time, about concepts of collaborative learning and educational robotics , focused on children digitally excluded. In this context was created a methodology that approaches many subjects as technological elements (e. g. informatics and robotics) and school subjects (e. g. Portuguese, Mathematics, Geography, History), contextualized in everyday situations. We observed educational concepts of collaborative learning and the development of capacities from those students, as group work, logical knowledge and learning ability. This paper proposes an educational software for robotics teaching called RoboEduc, created to be used by children digitally excluded from primary school. Its introduction prioritizes a friendly interface, that makes the concepts of robotics and programming easy and fun to be taught. With this new tool, users without informatics or robotics previous knowledge are able to control a robot, previously set with Lego kits, or even program it to carry some activities out. This paper provides the implementation of the second version of the software. This version presents the control of the robot already used. After were implemented the different levels of programming linked to the many learning levels of the users and their different interfaces and functions. Nowadays, has been implemented the third version, with the improvement of each one of the mentioned stages. In order to validate, prove and test the efficience of the developed methodology to the RoboEduc, were made experiments, through practice of robotics, with children for fourth and fifth grades of primary school at the City School Professor Ascendino de Almeida, in the suburb of Natal (west zone), Rio Grande do Norte. As a preliminary result of the current technology, we verified that the use of robots associated with a well elaborated software can be spread to users that know very little about the subject, without the necessity of previous advanced technology knowledges. Therefore, they showed to be accessible and efficient tools in the process of digital inclusion

Modelo arquitetural de comunicação para monitoramento de pacientes baseado em middleware, computação móvel e ubíqua

Hospital Automation is an area that is constantly growing. The emergency of new technologies and hardware is transforming the processes more efficient. Nevertheless, some of the hospital processes are still being performed manually, such as monitoring of patients that is considered critical because it involves human lives. One of the factors that should be taken into account during a monitoring is the agility to detect any abnormality in vital signs of patients, as well as warning of this anomaly to the medical team involved. So, this master's thesis aims to develop an architecture to automate this process of monitoring and reporting of possible alert to a professional, so that emergency care can be done effectively. The computing mobile was used to improve the communication by distributing messages between a central located into the hospital and the mobile carried by the duty

Perspectivas de inserção da energia solar fotovoltaica na geração de energia elétrica no Rio Grande do Norte

The generation of electricity in Brazil is predominantly renewable, with internal hydraulic generation being more than 70% of its energy matrix. The electricity rationing occurred in 2001 due to lack of rain, led the country to increase the participation of alternative energy sources. This need for new sources of energy makes the regional potential to be exploited, which configures the change of generation model from centralized generation to distributed generation. Among the alternative sources of energy, the solar energy is presented as very promising for Brazil, given that most of its territory is located near to the equator line, which implies days with greater number of hours of solar radiation. The state of Rio Grande do Norte (RN) has one of the highest levels of solar irradiation of the Brazilian territory, making it eligible to receive investments for the installation of photovoltaic solar plants. This thesis will present the state-of-the-art in solar photovoltaic power generation and will examine the potential for generation of solar photovoltaic power in Brazil and RN, based on solarimetrics measurements conducted by various institutions and also measurements performed in Natal, the state capital

Aproveitamento de resíduo de caulim em cerâmica branca

The world market of Kaolin has been growing as new investments for better quality of materials have been applied. This market produces amounts of dross that are put in the environment in a wrong way, causing damages to it. Trying to reduce these damages, researches have been done in an attempt to use kaolin dross in ceramic. The disposal of kaolin dross in the environment by the industries of the states of Rio Grande do Norte and Paraiba have great impact in society. Usually this dross is disposed clandestinely in places like roads, river banks and lands of small cities. The present work shows the characteristics of the kaolin produced by the mining company in Junco do Seridó, Paraiba state, western Seridó, 300 km from Natal, in the border of both states. After that, researches were done to study its physical and the chemistry characteristics, trying to see if it can be used in white ceramic. The samples got were bolted in fabric of 325# . The technological characteristics tried to use it as a product in white ceramic. For that, it was made a haracterization of the subject matter through enlargement analyses, ATG and ATD, elaborating three formulations that were burned in four different temperatures, 1175, 1200, 1250 and 1300 degrees centigrade up to 30 minutes. After the burning, the subjects were submitted to water absorbing tests, linear retreating, apparent porosity, apparent specific mass, resistance to flexibility and MEV. For one of the mixtures it was obtained demanded properties for a semi porous material

Estudo de formulação de massa para aplicação em placas cerâmicas

The sector of civil construction is strongly related to the red ceramic industry. This sector uses clay as raw material for manufacturing of various products such as ceramic plates. In this study, two types of clay called clay 1 and clay 2 were collected on deposit in Ielmo Marinho city (RN) and then characterized by thermogravimetric analysis (TG/DTG), differential thermal analysis (DTA), X-ray diffraction (XRD), X-ray fluorescence (XRF), rational analysis and particle size distribution and dilatometric analyses. Ceramic plates were manufactured by uniaxial pressing and by extrusion. The plates obtained by pressing were produced from the four formulations called 1, 2, 3 and 4, which presented, respectively, the following proportions by mass: 66.5% clay 1 and 33.5% clay 2, 50% clay 1 and 50% clay 2, 33.5% clay 1 and 66.5% clay 2, 25% clay 1 and 75% clay 2. After firing at 850, 950 and 1050 °C with heating rate of 10 °C/min and soaking time of 30 minutes, the following technological properties were determined: linear firing shrinkage, water absorption, apparent porosity, apparent specific mass and tensile strength (3 points). The formulation containing 25% clay 1 produced plates with most satisfactory results of water absorption and mechanical resistance, because of that it was chosen for manufacturing plates by extrusion. A single firing cycle was established for these plates, which took place as follow: heating rate of 2 °C/min up to 600 ºC with soaking time of 60 minutes, followed by heating using the same rate up to 1050 ºC with soaking time of 30 minutes. After this cycle, the same technological properties investigated in the plates obtained by pressing were determined. The results indicate (according to NRB 13818/1997) that the plates obtained by pressing from the mixture containing 25 wt% clay 1, after firing at 1050 °C, reach the specifications for semi-porous coating (BIIb). On the other hand, the plates obtained by extrusion were classified as semi-stoneware (group AIIa)
