Avaliação da aprendizagem no curso a distância de licenciatura em ciências biológicas da Universidade Estadual de Pernambuco

In contemporary society, distance education is expanding, especially in the offering of courses of initiatory professor training. By the side of possibilities, there is the need to critically reflect on the government decision to finance, and even to incite distance education, as a more economic way to achieve, within different time and space, the greatest quantity of the population, trying to fill the gaps of the Brazilian school education. The research was made in the Biology Bachelor Course offered by the Pernambuco University (UPE), in the context of the Presential Support Pole of the Paraiba State University, located in the city of Campina Grande. Along this study, we intend to analyze the evaluation practice and the instruments of valuation available in the virtual environment of learning (AVA), used by the former professors in the learning evaluation of the contents offered by the reference course. The relevance of the discussion is to reflect about the results of distance education in the initial of the professor training. To perceive the possibilities and limitations concerning the technological resources available at the educational process, especially to the evaluation practice, is primordial in order to comprehend the contents of learning that can be explored by the professors and which is the dialogical relation that is firmed between professor, preceptor and student, in favor of the learning development and an effective and meaningful education. The qualitative research had the symbolic interacionism as a methodological-theoretical approach. We gathered informations through institutional documents, documental records, questionnaires and semi-structured interviews. Treating and analyzing the data we used the content analysis method (Bardin, 1977). As a theoretical basis, we relied on authors such as Zabala (1998, 1999), Aretio (2002), Hoffmann (2003, 2005), Silva, M. (2003, 2006), Belloni (2006), Luckesi (2008), Silva, J. (2008), Vasconcelos (2008) and Domingos (2009). It was evident the need to reflect about the educational practice of the professors and preceptors responsible for the academic distance learning, concerning the evaluation of the learning contents in a autonomous and innovatory way, identifying its influence in the development of values which are considered vital to a complete professor upbringing. The evaluation in a mediator approach is necessary to the reality of an online classroom, because of its character to promote the improvement of the action of the one who is teaching and the one Who is learning in an interactive, collaborative and cooperative perspective, seeking a transformative praxis. Involved in this formation, the bachelors will be able to promote the development of capacities and skills necessary to the complete learning of theirs future students, certifying the education for life, which is a perspective that includes the knowing, the knowing how to do and how to be, a living being with sustainable relations with the others and with nature

Mecanismos sócio-genéticos da representação social de trabalho docente por grupos de licenciandos de física e de química da Universidade Federal do Rio Grande do Norte

This research aims to understand the social representations Teaching Work in groups of undergraduate students of Physics and Chemistry of the Federal University of Rio Grande do Norte. For this, the proposal was based on the three theoretical and methodological consensus Carvalho (2012) in the explanation of socio-genetic mechanisms constituents of dynamic consensus that has functionality to your organization. It Was used to achieve this goal, the theoretical-epistemological Serge Moscovici (1978, 2003), Jodelet (2011), Wagner (1998,( 2011) and Carvalho (2012). The corpus analyzed results from a qualitative and quantitative research, developed in three stages. The first two (2) questionnaires to fifty (50) of each undergraduate course, a questionnaire and another profile for collection of free associations concerning motes inductors "Give Lesson," "Student" and "Teacher". The second step in the procedure Multiple Classifications, Roazzi (1995), aimed for another thirty (30) undergraduate students for each course, as well as Document Analysis of Educational Projects Curriculum courses in Physics and Chemistry. The data analysis of the first stage focused on descriptive statistics and frequency and average order of the words associated with motes inductors. The results from the Multiple Classification Procedure submitted to multidimensional analysis (MSA multidimensional scalogram analysis) and SSA (Similarity Structure Analysis), were interpreted by the theoretical and methodological proposal of the three consensus, supported by analysis of the rhetorical nature of justifications classifications and categorizations of words, boosted in times of application of Procedure Multiple Classification. The data revealed that the groups surveyed were the same Social Representation with specific dynamic consensual. Thinking Teaching Work for these groups it is considered in three dimensions: the BE-DO-HAVE of teaching. In the group of Physics consensus was clear semantic, which expressed a dynamic in which the interpretations of "Teaching Work" peacefully coexist on perceptions of two concepts: An identity around the "BE" "Teacher" or "BE" "Educator" and the other, how they think about professional development. The type of group consensus Chemistry pointed to a consensual logic hierarchical order in which the gradual between the elements of BE-DO-HAVE attested conflicts and disagreements about the perceptual object "Teaching Work", around what value most, whether they are the attributes of personal or professional-technical dimension of teaching, in the course of professional development. The thesis to explain the mechanisms of socio-genetic Representation Social Teaching Work by theoretical and methodological proposal was confirmed

Campo educacional e representação social da formação docente :o olhar dos agentes

Teaching formation has been the target of many changes, having been forged according to numerous formats and models through different times and spaces, composing thus, different codes and curricular proposals for different levels of qualification. We've tried in this work to pinpoint the main discussions which take place in the area of the teaching formation, based in the views of modern writers. We ve also tried, through the Social Representations Theory, to reveal and learn how the agents directly involved in this process realize and react, that is, the teachers who cope with the beginning stages of the Fundamental Teaching in the public school system in Natal/RN, taking into account that, in many cases, such formation demands the rethinking of the very formation policies. We've also adopted the concepts of field and educational field introduced by the praxiology of Pierre Bourdieu. It s been considered a fundamental theoretical reference which enables the understanding of social phenomena, both in macro and micro viewpoints. Thus, we do not neglect the whole, and particularly, the nuances of each context or specific situation. In the methodological track we ve used for data gathering the Free Word Association Test, and the Semi-Structured Interview, and also secondary sources for the characterization of the research spectre. Data treatment and analysis were performed with the help of the following software: SPSS Statistical Package for Social Sciences and EVOC; and the method of Content Category Analysis. The combination of the concepts and techniques mentioned above was necessary to cope with the qualitative and quantitative aspects, in our attempt to offer a wider range of contributions and outcome validations, which have shown, among other less explicit elements, the existence of a social representation of the teaching formation such as: knowledge theoretical and practical; a necessity imposed by the symbolical conflicts of the social field; capacitation and compromisse. We acknowledge the relevance of the thoughts discussed here, though aware that this is just one of the possible approaches to the theme

A formação do enfermeiro na reflexividade

The study proposes an understanding of nurses training in reflexivity and the overcome the limits of biomedical formation model, from the thought of John Dewey, inserted in the panorama of the reflective practitioner introduced by Donald Schön and dialoguing with the perspective of the transforming action of Paulo Freire. We used a qualitative approach to collect empirical data through focus groups conducted with nursing students from 3rd to 5th year in the Faculty of Health Sciences, Trairi / UFRN in the year 2012. Data analysis occurred through the technique of thematic content analysis constituted of three stages: pre-analysis, exploration of the material, treatment of results, inference and interpretation of the material. Thus, the categories formulated by organizing, classifying and aggregating the the content of the speeches to groups who shared opinions approximations of thought generating a set of categories of analysis designed from the contents. The results present the experiences of nursing students and their reflections, demonstrating that the process of reflection permeates the journey of life. It is inferred that the knowledge acquired in these experiences do not always participate in this dialogue in this formative process, reducing previous experiences in the field of exemplification of everyday situations. We conclude that it is necessary to consolidate innovative pedagogical proposals that allow the continuous dialogue with reality, breaking with the decontextualized teaching process from reality insertion of the university. Rethinking of the structures is recommended, reinforcing the break with the biomedical model and the integration of knowledge dynamically

Desempenho de híbridos de milho submetidos a diferentes espaçamentos e densidades populacionais

O objetivo deste trabalho foi avaliar a influência de espaçamentos entre linhas e densidades populacionais, nos componentes de produção e na produtividade de grãos, em dois híbridos de milho (Zea mays). O experimento foi conduzido na safra 2006/2007, em Latossolo Vermelho eutrófico típico, textura argilosa, em Jaboticabal, SP. O delineamento experimental de blocos ao acaso foi composto por 24 tratamentos com parcelas subsubdivididas. As parcelas principais foram constituídas por três espaçamentos entre linhas (0,40, 0,60 e 0,80 m), as subparcelas, por dois híbridos e as subsubparcelas, por quatro densidades populacionais (30 mil, 50 mil, 70 mil e 90 mil plantas por hectare). Foram avaliadas as variáveis: altura de planta e altura da inserção da primeira espiga, diâmetro de colmo, número de grãos por espiga, massa de 1.000 grãos, produtividade de grãos e índice de colheita. A produtividade do milho aumentou com a redução do espaçamento entrelinhas para os híbridos avaliados. O incremento na densidade populacional de milho resultou em aumentos na altura das plantas e na altura da inserção da primeira espiga e em redução do número de grãos por espiga. O melhor arranjo de plantas para os híbridos avaliados é de 0,40 m de espaçamento entre linhas e de 75 mil e 80 mil plantas por hectare de densidade populacional.

Adubação nitrogenada em cultivares de arroz de terras altas

O objetivo deste trabalho foi avaliar a influência de diferentes doses de N em cobertura (0, 30, 60, 90 e 120 kg ha-1) sobre as características agronômicas de diferentes cultivares de arroz de terras altas (Caiapó, Primavera, Confiança, IAC 202 e Carisma) sob irrigação por aspersão durante os anos agrícolas 2003/04 e 2004/05, em área experimental da FCAV - UNESP - Jaboticabal (SP). Os cultivares Caiapó, IAC 202 e Carisma são os de maior produtividade, com o Primavera não respondendo ao incremento da adubação nitrogenada; o IAC 202 e Carisma são possuidores de índice de colheita mais elevado e responsivos ao nitrogênio aplicado em cobertura, sugerindo-se indicá-los para sistemas produtivos mais evoluídos; o cultivar Caiapó demonstra ser mais eficiente em absorver e utilizar o N contido no solo, sugerindo sua indicação para sistemas produtivos de menor aporte de tecnologia.

Características agronômicas e qualidade comercial de cultivares de milho pipoca em alta população

Com o objetivo de identificar cultivares de milho pipoca que se constituam em alternativa viável aos produtores foi conduzido um experimento em delineamento experimental de blocos casualizados, com cinco genótipos de milho pipoca (BRS Ângela, Zélia, IAC 112, IAC 12 e IAC TC-01) e quatro repetições, na safra 2003/2004. O experimento foi instalado em espaçamento entre as linhas de 60 cm, com densidade populacional de 75 mil plantas por hectare. No decorrer do experimento, foram avaliadas características agronômicas e comerciais em condição de campo e de laboratório. A variedade BRS Ângela apresentou maior produtividade, seguida pelos híbridos simples IAC, com Zélia (híbrido triplo) apresentando menor produtividade. O híbrido simples IAC 12 apresentou pior qualidade comercial de pipoca. A produção de grãos está associada positivamente com o número de grãos por espiga e com a massa de 1.000 grãos e negativamente com o teor de Ntotal no grão. A qualidade comercial se correlacionou negativamente com a massa de 1.000 grãos.

Suscetibilidade de genótipos de feijão ao vírus-do-mosaico-dourado

O objetivo deste trabalho foi avaliar a suscetibilidade de diversos genótipos de feijão ao vírus-do-mosaico-dourado (VMDF), transmitido pela mosca branca (Bemisia tabaci). A semeadura foi realizada na época da seca e das águas, com e sem aplicação do inseticida granulado Aldicarb (3,0 kg ha-1 do i.a.) no sulco de semeadura. O delineamento experimental utilizado foi o de blocos casualizados disposto em esquema fatorial 14x2, representado por genótipos e inseticida, respectivamente, com quatro repetições. A maior infestação de mosca-branca e incidência do vírus ocorreu na época da seca, causando prejuízos à produção do feijoeiro. Os genótipos apresentaram diferentes graus de suscetibilidade ao vírus e ao inseto vetor. Os genótipos mais tolerantes foram IAPAR 57, IAPAR 65, IAPAR 72, Ônix, Aporé e 606 (5)(214-17). A aplicação do inseticida sistêmico controla o vetor em ambas as épocas de cultivo, proporcionando aumentos da produtividade.

Efeito do paclobutrazol e de ácido giberélico na indução floral do maracujazeiro-amarelo em condições de entressafra

Objetivou-se estudar os efeitos de ácido giberélico (GA3) (i.a.), nas concentrações de 50 e 100 mg L-1, acrescido do espalhante adesivo Extravon® a 0,05%, em duas aplicações via foliar e do paclobutrazol (PBZ) (i.a.), em doses de 2 e 4 g por planta, aplicado via solo, em uma única aplicação, na antecipação da floração do maracujazeiro-amarelo, em Araguari-MG. O delineamento experimental empregado foi em parcelas subdivididas, com cinco tratamentos (parcelas) e dois tratamentos (subparcelas), com quatro repetições e quatro plantas por parcela. Foram identificados 12 ramos terciários por parcela, com seis ramos expostos à luminosidade predominante pela manhã e seis com luminosidade predominante à tarde. Avaliaram-se os dois lados da espaldeira aos 103 dias após a primeira aplicação dos tratamentos, observando-se o comprimento dos ramos e de entrenós, número de nós e de botões florais. Os reguladores não promoveram respostas significativas para o comprimento dos entrenós e o número de botões florais. Porém, observaram-se indícios de maior número de botões florais com PBZ 2 g. O maior comprimento dos ramos foi obtido com GA3 100 mg L-1, sob luminosidade, pela manhã. Ao se compararem os tratamentos nas duas condições de luminosidade, o PBZ 4 g, independentemente da condição de luminosidade, proporcionou o menor comprimento dos ramos.

Características físico-químicas do grão de cultivares de arroz em função da adubação nitrogenada

Rice (Oryza sativa L.) stands out as a staple food of the world population due to important nutritional properties. However, rice physico-chemical parameters vary according to genotype and management, for example, the use of nitrogen fertilizer. The aim of this work was to evaluate physico-chemical parameters of grains from thirteen cultivars of upland rice under supplemental sprinkler irrigation and fertilized with different nitrogen rates by topdressing (0, 40, 80, 120 and 160 kg ha(-1)). Parameters such as milling efficiency, commercial grade, gelatinization temperature, as well as total nitrogen and crude protein contents of grains were evaluated. Nitrogen fertilization positively influences the whole grain yield, especially IAC 25 and BRS Colosso. BRS Aroma, IAC 202, IAC 500, BEST 2000, Curinga and Baldo have a high percentage of broken grains. The cultivars Baldo and Carnaroli (appropriate for Italian cuisine), IAC 25 and Caiapo are classified as long grain and the others, as long-thin. The cultivars, except CIRAD 141, displayed grain gelatinization temperature between intermediate and low, providing quick cooking. The grain content protein varies among cultivars, and it can be increased with nitrogen fertilization.

Adubação nitrogenada de cobertura no feijoeiro de invernoprimavera em três sistemas de cultivo

The aim of this study was to evaluate the nitrogen topdressing influence in common bean irrigated (winter-spring), in the first year of no tillage implementation. The experimental design was split-plot with three replications in randomized blocks. The plots were formed by three types of ground cover, corn-grain, corn-grain intercropped with Brachiaria ruziziensis and only B. ruziziensis. The subplots were formed by five doses of nitrogen topdressing (0, 40, 80, 120 and 160 kg ha(-1)), using urea as nitrogen source. It was determined the dry mass of residue present as ground cover, the full flowering time, the leaf nitrogen content, the 100 grains mass, the grain yield, the processing income, the chemical soil properties and economic analysis of common bean grain yield. It was found the common bean grain productivity in succession to corn-grain was positively influenced by nitrogen fertilization, showing it is economically viable only when given 160 kg ha(-1) of nitrogen and the intercropping corn-grain and B. ruziziensis use is the best option when the common bean is sown in succession.
