Transição demográfica e a questão educacional: uma abordagem para o ensino médio do Rio Grande do Norte

Due to demographic transition process, the educational public sector politics formers encounter a highly specific demographic situation because, nowadays, despite the demographic transition, population is still growing because of the demographic inertia; however, due to steady decline in fertility, young population tends to decrease in next years. In this way, aiming to make high school widely accessible in the country, the issue of education quality is highlighted as well the importance of the physical structure of schools and their teaching equipments to confirm a favorable or not environment for developing educational processes. In this way, this work aims to relate the enrollment of students as school types with the demand of young people who will be able to attend high school on the Rio Grande do Norte state by the year of 2020, emphasizing teaching unities structural aspects, from a school profiling to the design of three prospective alternatives. So, from INEP's Scholar Census data and IBGE population's projections, this work is composed by four stages: i) literature review about research related subjects; ii) database design and build; iii) school profiling; and, iv) prospective alternatives creation. As results, three alternatives relate potential demand and enrollment using the built profiles and they are: i) “Alternative A” attends PEE's requirements related to demands but do not provide improvements in the school structural aspects; ii) “Alternative B” points into an increase of enrollment offering to the detriment of school's structural conditions which are offered to these students; iii) “Alternative C” propitiates a quantitative enrollment increasing combined with improvements on school's physical structure. These alternatives help to support decision making related to goals and realization of universal access with physical conditions which are necessary to a favorable environment to educational activity development.

O Ensino de ligações químicas por meio do conceito de energia: uma proposta didática para o ensino médio

This work presents discussions on the teaching of Chemical Bonds in high school and some implications of this approach in learning chemistry by students. In general, understanding how the chemicals combine to form substances and compounds, it is a key point for understanding the properties of substances and their structure. In this sense, the chemical bonds represent an extremely important issue, and their knowledge is essential for a better understanding of the changes occurring in our world. Despite these findings, it is observed that the way in which this concept is discussed in chemistry class has contributed, paradoxically, to the emergence of several alternative designs, making the understanding of the subject by students. It is believed that one of the explanations for these observations is the exclusive use of the "octet rule" as an explanatory model for the Chemical Bonds. The use of such a model over time eventually replace chemical principles that gave rise to it, transforming knowledge into a series of uninteresting rituals and even confusing for students. Based on these findings, it is deemed necessary a reformulation in the way to approach this content in the classroom, taking into account especially the fact that the explanations of the formation of substances should be based on the energy concept, which is fundamental to understanding how atoms combine. Thus, the main question of the survey and described here of the following question: Can the development of an explanatory model for the Chemical Bonds in high school based on the concept of energy and without the need to use the "octet rule"? Based on the concepts and methodologies of modeling activity, we sought the development of a teaching model was made through Teaching Units designed to give subsidies to high school teachers to address the chemical bonds through the concept of energy. Through this work it is intended to make the process of teaching and learning of Chemical Bonds content becomes more meaningful to students, developing models that contribute to the learning of this and hence other basic fundamentals of chemistry.

Contradições como força de mudança: o processo de formação continuada de professores do ensino médio enquanto potencializador da práxis transformadora à luz da teoria histórico-cultural

The intervention research proposed was based on the Cultural-Historical Theory based on the laws and logic of materialism historical-dialectical. Therefore, we tried to design a research process that involved all as responsible for the process. In the field of continuous teacher's training usually has been found dualistic relationship / paradoxical processes as a result of the adopted training models which are characterized by individualist human processes. The teacher training work sought to overcome this dualism, to promote the unveiling of the contradictions with regard to teaching models. As a hypothesis, we imagined that immersed in this process, teachers recognize such contradictions, and this recognition would make the contradictions become the driving force of change in teaching practice, realizing the teaching-learning-development triad as the basis of praxis. Aiming to develop a process of continuing education to bring results to the professional teachers development looking for answer the following research question: How and what the changes of teachers who participated in the Didactic-Formative Intervention process raised the quality of their teaching practices? In this context, the objective of the research was to develop a process of Didactic-Formative Intervention from the perspective of Cultural-Historical Theory with high school teachers in order to theorize about the changes in pedagogical practices of teachers and learn aspects that transform the essence teaching practice. The research involved two high school teachers of a public school in Uberlândia-MG. The training meetings took place at the school through a collective study group between the years 2013 and 2015. As procedures were used two interconnected aspects: classes observations, and a theoretical and methodological training, both for diagnosis and for the process evaluation, the second aspect has a formative dimension, and a didactic dimension (double meaning) to form didactically the teacher and to elaborate didactic procedures. The collected data were analyzed by observing the assumptions of the method, analysis by units and the processuality. As results teachers showed changes in their teaching practices regarding the organization of the pedagogical work and also centered their design educational actions based on learning and development of the students. The presence of continuous diagnosis during the classes, work with a systems of concepts and their conceptual links, problematization as a teaching method can be pointed as meaningful changes in their praxis. Regarding the training activities that emerged from the analysis of the compiled materials and analyzed throughout the process can be emphasized: forming a collective group of school teachers continuous training, diagnostics, development of practical activities, increase relationships among participants, the choice of scientific material used should have direct relation to the needs of the participants, promoting conditions that enable the emergence of contradictions between the pedagogical practice of teachers and teaching based on the perspective of the Cultural-Historical Theory. This research craved to develop and design a teachers' training processes that increase the quality of teachers life and ways of teaching in the Brazilian public school.

In this dissertation was elaborated an interdisciplinary didactic sequence for the development of Physical concepts involved in the interaction of laser radiation with biological matter in order to make a relation between Physics and other fields of knowledge aiming to enlarge the contextualization of scientific knowledge. The objective was to develop an educational product which theme is “Laser’s Interaction with Biological Tissues”. In this work, basic physical concepts related to laser radiation were presented, its interaction with matter and applicability in the student's daily life, with emphasis on Public Health. The inclusion of the subject in schools was effected through didactic transposition as theoretical foundation and the three pedagogical moments as teaching support. The development of the project involved discussions of scientific knowledge applied in society’s daily life. In the product's design the didactic sequence was projected and the use of varied teaching resources has been proposed, such as videos, texts, experiments, simulators and de Software “Tracker”. The construction of paradidactic material was performed considering different stages of equal importance for a teacher's reflection process. The work prioritizes the alternative conceptions of student, transforming him in a direct agent of the construction of knowledge and this aspect is based on the profile of the Student's Material. Another important point is the evaluation's proposal, this was systematized to be done class after class through building texts, essay questions, presentation of papers, among others activities. The didactic sequence guides the introduction of relevant topics of the students and society’s daily life, the ideas are not closed and in many times the teacher make changes which deem relevant to the teaching for better development of their practice.

Relações entre mecanismos de coordenação e controle com desempenho organizacional: um estudo nas instituições públicas de ensino médio de Natal

This research aimed at relating coordination and control forms to organizational performance. The multicase study was applied in two public high schools: Centro Federal de Educação Tecnológica do Rio Grande do Norte and Floriano Cavalcanti. In order to accomplish these objectives, it was developed a qualitative analysis and considered coordination and control forms of several authors. Also was considered Sander´s (1984) model of organizational performance. The mentioned model considers two criteria to analyze organizational performance: one instrumental (efficiency and efficacy) and other substantive (effectiveness e relevance). The research attempts to show the importance of balancing these criteria in a way that effectiveness and relevance becomes more important at schools. It was proven that the use of bureaucratic coordination forms has the power to influence the evaluation on the instrumental technique. At the same time, it was observed that the use of mechanisms based on the autonomy of the school is related to efficiency and efficacy. The object of this research can be considered successful

Significância histórica e as questões de gênero no ensino de história: um estudo de caso sobre as narrativas dos estudantes no ensino médio da Escola Professor Lorea Pinto

O objetivo deste trabalho consiste em analisar como os estudantes da turma de história do terceiro ano do ensino médio, da Escola Estadual Professor Carlos Lorea Pinto, situada em Rio Grande, elaboram narrativas no intuito de significar as questões de gênero através do pensamento histórico. Este trabalho segue as premissas teóricas da educação histórica e discute conceitos de significância, consciência histórica e narrativa, assim como faz uma reflexão sobre as questões de gênero, corpo e sexualidade no ensino de história. A metodologia deste trabalho contempla os pressupostos de pesquisas desenvolvidas na educação histórica, sendo um trabalho de cunho qualitativo que tem com objeto de análise as narrativas dos estudantes e está dividido em três fases. A primeira fase corresponde a questionamentos que busquem identificar as ideias prévias dos estudantes sobre gênero e ao contato dos estudantes com as fontes históricas selecionadas, essas fontes são o livro didático e um jornal. Através da utilização do próprio livro didático como fonte histórica e do contato como um jornal feminino do inicio século XX – o jornal riograndino Corymbo – os alunos irão elaborar e estruturar suas visões a respeito das questões de gênero. A segunda fase desta pesquisa diz respeito à produção de narrativas dos estudantes. Neste momento os alunos irão mobilizar seus pensamentos históricos para a produção de narrativas em formatos de jornais sobre a mulher. Por fim a terceira parte aborda a investigação destas narrativas e dos questionamentos feitos aos alunos, através da utilização da metodologia de análise de conteúdo. Este trabalho visa contribuir para que haja maior conhecimento sobre a forma como os estudantes apreendem história e demonstrar a importância da competência narrativa e da reflexão sobre as relações de gênero para o ensino de história.
