Matemática comercial e financeira com a utilização de recursos digitais: uma experiência no ensino médio

This work aimed to investigate the possible contributions of the use of digital resources in the teaching and learning process of Commercial and Financial Mathematics concepts to high school students. Its development has included a survey of some researches on the topic as well as an experimental study of a qualitative type, in which the Webquest was used as methodology. It uses the computer, more precisely the internet resources, to assist students in building up knowledge. Eight meetings were held, in the after-school period, with a group of students of the second year of high school at a state public school in the city of Guaratinguetá. Aiming to evaluate the knowledge that students had about the theme, it was applied a diagnosis at first glance for further analysis and development of activities and interventions according to the students’ answers. Once the research data was analyzed, it was noted that the students had little knowledge regarding the basic contents of Commercial and Financial Mathematics, in addition to presenting difficulties in handling some of the digital resources used in the meetings. Nonetheless, from the students’ works, it was seen significant advances in understanding and building up knowledge on concepts such as percentage, simple and compound interest, savings, and sales involving prompt payment or in arrears

Reflexões sobre a prática pedagógica nas atividades de ensino: monitoria, no ensino médio em escola particular e estadual em Rio Claro

The difficulties related to physics teaching are related to methodology, that hinder learning, because some physical concepts beyond the common sense of most students. Just as poor training of some physics instructors in teaching is pedagogical difficulties. And also factors of infrastructure, heterogeneity in students' previous training etc.. It is proposed aim of this work to use reflection of teaching practice as a methodology. Practiced in a private school, mostly state and, in high school in Rio Claro. The method consists of preparing a daily pedagogical practice in parallel to the development of teaching, for analysis and identification of factors that result in improving the teaching of physics and physics teacher qualification

Efeitos da experimentação no cotidiano letivo no ensino médio

In this work, it was studied the effects of the experimentation in the physics teaching. Beginning from the theoretic reference and discussions, the objective was prove the efficiency of researches of this nature related to two main aspects of a class: The aroused interest in the students and the facilitating action on the understanding of the theory. For such objective, using the comparison, it was chosen two distinct classes, but the more similar possible, so that, in one of them, it was showed a tradition class, lectures and in another, a class using experimentation to contemplate the theory. To manage a way to rate these aspects, it was made a conceptual questionnaire, requiring only concepts rather than mathematics and equations, besides specific interviews to rate the opinion of the student related to each method. The observations in classes and of the reactions of the students also were of a big value to analysis. After the experimental class completed, it may analyze and conclude some positive points related to experimental methods: As for the opinion of the students, the approval was big, and the majority opined to this class as being “more interesting”. On the point of view of learning, it had a sensitive improvement of grades, but with more mature answers, deep and autonomous, if looking at a general vision

Física de partículas no ensino médio: uma análise de materiais para apoio didático

This work consisted in analysing five materials which mean respect to subjects related to Particle Physics, aiming to explore their potentialities for the use in the High School levels, particularly by physics teachers. On this perspective, we sought to describe the contents of each material and point out their potentialities as material of didactic support. They are: 1. The purpose of Secretaria da Educação do Estado de São Paulo, presented in the Teacher's Guide of the Program São Paulo faz escola; 2. The Game Sprace Game, elaborated by the European Organization for Nuclear Research (CERN); 3. The book O discreto charme das partículas elementares, written by the professor Maria Cristina Abdalla; 4. The video O discreto charme das partículas elementares, based on the book of Professor Maria Cristina Abdalla which was produced by TV Cultura in association with the Ministério da Educação e Cultura” (MEC). The book Partículas elementares no ensino médio: uma abordagem a partir do LHC written by Wagner Franklin Balthazar and Alexandre Lopes de Oliveira, from the collection CBPF - Tópicos de Física. The work was constructed on a qualitative perspective, that is, it did not attempt to quantify the help that each material could offer to Physics teaching. One sought to describe and analyse, from different theoretical frames, their potentialities for the use in the High School level. The results indicate that all the materials analysed can contribute to the Physics teaching, and beyond, as they own format and approches distinct from the subject, they can be used as a whole or in parts, together or separately, depending on the objectives to be reached and on the profile of the target public

A crise na sociedade do trabalho e sua importância na contextualização dos conteúdos curriculares do ensino médio

This article has as objective to discuss some topics concerning the supposed crisis of the society of the work and its consequences for the debate in social sciences and also for the work category contextualization in the secondary school curriculum. As the work has represented an important explanation category for the classic social thought, the contemporary paradigm of deep metamorphoses in the world of the work and the advent of the new question (CASTELS, 1995; ROSANVALLON, 1995) backward the necessity to rethink the theoretical shades that base the interpretation of the social life on the current context, when the center position of the work is being questioned. Having taken some theoretical references from the sociology of the work, we search to delineate on a brief way the quarrel about the dimensions of the social and political phenomena these days and the importance of this debate on the contextualization of the secondary school curriculum contents.

Expectativas sobre os efeitos do uso de álcool e padrão de beber em alunos de ensino médio

Studies have shown that adolescents begin to make use of alcoholic beverages earlier and excessively, a behavior which has several negative consequences. Thus, the present study aims at investigating whether the expectations they have for the effects of alcohol consumption are high or low and if there is a relationship between expectation and consumption pattern. AUDIT and IECPA were applied as data collection instruments. The first indentifies the pattern of alcohol use and the second investigates the expectations the subjects have in relation to the use of alcohol. The results of this study, differently than others, do not evidence the positive relationship between binge-drinking and high expectations about the use of alcohol.

A Inserção da astronomia na grade curricular do ensino médio do Estado de São Paulo

We performed in this study an analysis of Curriculum Astronomy contents the public schools of São Paulo from the available educational materials to teachers and students by the state board of education. We analyzed the conditions that teachers carry out the activities suggested to the teaching-learning situations, considering factors such as time available for classes, available material and the general technical condition to perform the activities suggested by the material. Thereafter, we conducted a search with teachers from public of São Paulo, than three cities in the Vale do Paraíba, in order to trace a general framework of the perception of these teachers about the introduction of Astronomy in Physical during the implementation of the new curriculum

Atividades investigativas: o impacto na capacidade de argumentação em alunos do ensino médio sobre eletroquímica

The education research guidelines have shown the important contribution of the investigations that focus on analysis of the discursive dimension of teaching and learning of Science in actual classroom. An interesting proposal to analyze the effectiveness of an educational activity is to assess the potential of investigative activities in the development of argumentation in science classes. Several studies have taken into account the use of argument in the classroom as a way to provide students with new ways to know the science. Argument refers to the process of associating components that play a central role in the construction of explanations, models and theories. In order to investigate the potential of these activities took place the application of investigative activities with third-year high school students, recorded in audio and video, focusing on the development of the argument. The search, conducted ranks as a qualitative research with characteristics of a case study. The arguments collected during the activities contained the students' conceptions about the concepts discussed and all were recorded in audio and video. With the encouragement of the argument by the investigative activity we evaluate the learning experienced by the speech of students. It may be noted that students have appropriated the concept of oxidation involving electron transfer, thus the activity reached the goal, so that was planned, making it effective for the introduction of electrochemical concepts

Metas de inflação no Brasil (1999-2012): uma análise institucional

The paper shows the advantages and handicaps of implementing an inflation target (IT) regime, from post-keynesian and institutional stances. It is post-keynesian as long as it does not perceive any benefit in the mainstream split between monetary and fiscal policies. And it is institutional insofar as it shows there are several ways of implementing a policy, such that the chosen one is determined by historical factors, as illustrated by the Brazilian case. Thus, one could even support IT policies if their targets were seen just as “focusing devices” guiding economic policies, but also regarding with due attention other targets, as, in the short run, output growth and employment and, in the long run, technology and human development. Therefore, an IT is not necessary, although it can be admitted, mainly if the target is hidden from the public, in order to increase the flexibility of the central bank.

Representações sociais de professores sobre indisciplina no ensino médio e técnico

O objetivo do presente estudo foi identificar as representações sociais de professores sobre indisciplina em sala de aula. Adotamos a teoria das Representações Sociais como referencial teórico. Os dados foram coletados por meio de entrevistas individuais semiestruturadas. Os participantes foram três professores do ensino técnico, três do ensino médio e três de ambos os ensinos, totalizando nove docentes de uma Escola Técnica Estadual (ETEC) do interior paulista, pertencente ao Centro Estadual de Educação Tecnológica Paula Souza. Utilizando a análise de conteúdo, definimos três eixos temáticos: causas atribuídas à indisciplina, alternativas para lidar com a questão e concepção de indisciplina, para os quais caracterizamos categorias, em que obtivemos a frequência de respostas. Na análise dos resultados, podemos indicar que a representação social da indisciplina parece estar objetivada, principalmente, nas questões individuais dos alunos. Os professores relataram diferentes causas da indisciplina para os ensinos médio e técnico. Foram indicadas algumas diferenças na maneira de lidar com o aluno adolescente e adulto e entre as causas e as alternativas para lidar com a indisciplina. As representações sociais dos professores sobre a indisciplina ancoraram-se, em sua maioria, num referencial tradicional, associado à responsabilização do aluno e da família.
