Literacia científica e trabalho prático: um estudo para a inovação pedagógica em contexto escolar

Na presente tese o Trabalho Prático (TP) foi analisado procurando-se discernir as suas potencialidades na criação de práticas pedagógicas heterodoxas onde o aluno seja socialmente participativo na construção de conhecimento. A investigação fundamentou-se na metodologia etnográfica, tendo a recolha de dados ocorrido durante o desenvolvimento de TP na disciplina de Biologia do 12ºAno de escolaridade. A análise reflexiva dos dados permitiu compreender as vivências culturais do grupo turma, possibilitando criticar as práticas pedagógicas desenvolvidas como continuidade ou rutura com o modelo tradicional de ensino. As conclusões apontam para a importância do TP na humanização da ciência e para a necessidade de conjugar diferentes modalidades de TP, vincando a dimensão social, enquanto meio para o desenvolvimento da Literacia Científica dos alunos. Esta implica que o conhecimento seja socialmente construído, envolvendo a partilha e negociação de uma rede comum de significados. Para tal, o trabalho de grupo aparece como matriz de desenvolvimento do TP potenciado pela democratização do acesso à informação possibilitada pelo uso das Tecnologias da Informação e Comunicação (TIC). Neste âmbito, a heterogeneidade cultural dos alunos da turma é uma mais valia na prática social e a customização da aprendizagem uma possibilidade, indiciando potencialidades do TP para a criação de práticas pedagógicas incomuns.

A iluminação cênica no trabalho do ator de teatro

This research aims to investigate how the stage lighting can be articulated in the creation of theater actor process. To we reach this reflection, it is necessary to understand the space of the rehearsal room, where the actor works as a place where their function receives influences of other artists who are creating the spectacle.Collaborative processes are analyzed three Cia de Teatro Engenharia Cênica: Irremediável, 2007; Doralinas e Marias , 2009; O Menino Fotógrafo, 2011, aiming to understand the collaborative theater potentializes, the intersection and the exchange of experiences in the rehearsal room, collaborating actively for the training of persons involved in creating the show. The research proposes an investigation of how the creative process of stage lighting is gaining ground in the rehearsal room in the language of theater directing, showing mainly how is your "co-evolutionary" creation with the creative process of the actor

Investigação e avaliação da toxicidade aguda dos agrotóxicos mais utilizados no cinturão verde da Grande Natal (RN, Brasil) para o peixe-zebra (Danio rerio Hamilton Buchanan, 1822, Teleostei, Cyprinidae

The objectives of this research were to investigate the agrotoxic most used in the Gramorezinho region in the green belt of Natal, and to evaluate the acute toxicity of these, based on the LC50-48h values estimated in tests for Danio rerio, internationally used as test organism. The acute toxicity tests were performed under laboratory conditions, according to standardized methods (ABNT/NBR/15088/04) for this species. The LC50-48h estimated to Tamaron BR was 352.89 mg.L-1, which characterizes that as practically non-toxic, according to toxicological classes cited by Zucker. For Decis 25EC, the LC50-48h estimated was 0.0004156 mg.L-1 (4.156 X 10-4 mg.L-1), which classifies it as highly toxic to this species

Nitretação em plasma com gaiola catódica: investigação do mecanismo e estudo comparativo com a nitretação em plasma de tensão contínua

The ionic plasma nitriding is one of the most important plasma assisted treatment technique for surface modification, but it presents some inherent problems mainly in nitriding pieces with complex geometries. In the last four years has appeared a plasma nitriding technique, named ASPN (Active Screen Plasma Nitriding) in which the samples and the workload are surrounded by a metal screen on which the cathodic potential is applied. This new technique makes possible to obtain a perfect uniform nitrided layer apart from the shape of the samples. The present work is based on the development of a new nitriding plasma technique named CCPN (Cathodic Cage Plasma Nitriding) Patent PI 0603213-3 derived from ASPN, but utilizes the hollow cathode effect to increase the nitriding process efficiency. That technique has shown great improvement on the treatment of several types of steels under different process conditions, producing thicker and harder layers when compared with both, ASPN and ionic plasma nitriding, besides eliminating problems associated with the later technique. The best obtained results are due to the hollow cathode effect on the cage holes. Moreover, characteristic problems of ionic plasma nitriding are eliminated due to the fact that the luminescent discharge acts on the cage wall instead of on the samples surface, which remains under a floating potential. In this work the enhancement of the cathodic cage nitriding layers proprieties, under several conditions for some types of steels was investigated, besides the mechanism for nitrides deposition on glass substrate, concluding that the CCPN is both a diffusion and a deposition process at the same time

Investigação e gerenciamento de áreas contaminadas por postos revendedores de combustíveis em Natal

Activities that have fuel subterranean storage system are considered potentially polluting fuels by CONAMA Resolution 273, due to the possibility of leak, outpouring and overflow of fuel into the ground. Being even more worrying when contaminate groundwater for public supply, as the case of Natal City. For this reason, the Public Ministry/RN, in partnership with UFRN, developed the project environmental suitability of Gas stations in Natal, of which 36% showed evidence of contamination. This paper describes the four stages of the management of contaminated areas: preliminary assessment of environmental liabilities, detailed confirmatory investigation of the contamination, risk analysis to human health (RBCA), as well as the remediation plan of degraded areas. Therefore it is presented a case study. For the area investigated has been proposed a mathematical method to estimate the volume of LNAPL by a free CAD software (ScketchUp) and compare it with the partition method for grid area. Were also performed 3D graphics designs of feathers contamination. Research results showed that passive benzene contamination in groundwater was 2791.77 μg/L, when the maximum allowed by CONAMA Resolution 420 is 5 μg/L which is the potability standards. The individual and cumulative risks were calculated from 4.4 x10-3, both above the limits of 1.0 x10-5 or by RBCA 1.0 x10-6 by the Public Ministry/RN. Corrective action points that remediation of dissolved phase benzene is expected to reach a concentration of 25 μg/L, based on carcinogenic risk for ingestion of groundwater by residents residential, diverging legislation. According to the proposed model, the volume of LNAPL using the ScketchUp was 17.59 m3, while by the grid partitioning method was 14.02 m3. Because of the low recovery, the expected removal of LNAPL is 11 years, if the multiphase extraction system installed in the enterprise is not optimized

Efeito da natação e do basquetebol em cadeira de rodas sobre o colesterol HDL: uma investigação em indivíduos com lesão medular

Despite the observation of an increase in life expectancy in individuals with Spinal cord injury (SCI), it is lower than that of the general population. Studies have shown that affected individuals have a sedentary lifestyle that reflects negatively on health and quality of life. Studies have demonstrated that HDL cholesterol (HDL-C) levels, a high-density lipoprotein and important predictor of cardiovascular disease, are lower in this population exposing these people to a greater incidence of heart disease from atherosclerotic process In the general population, exercise increases HDL-C serum levels, but this phenomenon is not very clear in people with spinal cord injury (SCI). The present study examined the effect of both swimming and wheelchair basketball in the lipid profile of eleven men and seven women with SCI. The subjects included in regular exercise programs showed increases in HDL-C levels and decreases in CT/HDL-C and LDL-C/HDL-C ratios. We found better results mainly in men with lower levels of SCI and in those that sustained exercise intensities above 60% of the heart rate reserve. The duration of training sessions can be an essential factor in these results. The results suggest that both the exercise prescription and the personal characteristics of people with SCI influence changes in the lipid profile mediated through exercise. The elaboration of this work is an attempt to clarify uncertainties about health and the longevity of people with SCI generated in discussion of all members of the interdisciplinary rehabilitation team, especially the physiotherapists, nutritionists, nurses and physicians that contributed considerably in all phases of the research

Investigação das alterações citogenéticas em pacientes pediátricos com leucemia linfóide aguda do Rio Grande do Norte

Leukemia is a heterogeneous group of hematologic malignancies that result from partial or total transformation of the blast cells. The Acute Lymphoblastic Leukemia (ALL) is the most common malignancy in childhood, especially in male, Caucasian children younger than 14 years. Several criteria are adopted to classify ALL, including the cell morphology, cytochemistry, immunophenotyping and cytogenetic analysis. Cytogenetic studies allow a more detailed analysis to detect chromosomal abnormalities of leukemic cells. These modifications will determine the diagnosis, classification, stage characterization, remission assessment and prognosis. In this study were evaluated 30 patients, aged from four months to seventeen years, of both sexes and various ethnicities. The age distribution showed that 67% of patients had between one and ten years (with mean age of XX years old), the most prevalent ethnic was Caucasian (50%) and 57% were males. According to immunophenotype, 93% of patients had B-cells progenitor ALL and 7% early lineage T. Considering the total studied population, the most frequent medical findings were lymphadenopathy (37%), hepatomegaly (77%) and splenomegaly (70%), where one patient could present more than one of these medical findings. Regarding the CBC, the majority of patients had hemoglobin below 10 g / dl (73%), leukocyte count less than 10.000/μL (60%) and platelet count below 150.000/μL (83%). Chromosomal abnormalities were observed in 64% of all patients, where hyperdiploidy was the most common numerical change (67%), followed by hypodiploid (33%). All these data are in agreement with the literature. Moreover, complexes structural and/or number changes not yet described in literature were observed, which indicated poor prognosis. Finally, we concluded that this study demonstrated the importance of cytogenetic study in the diagnosis and identification of prognostic factors in pediatric patients with ALL in Rio Grande do Norte. The results obtained in this study are extremely useful and emphasizes that surveys of this nature must be conducted more frequently in our state

A reestruturação produtiva e as novas formas de organização do trabalho: a experiência do transporte alternativo no município de Belém/PA

The study made in this thesis analyzes the new form of work organization at the urban collective transportation sector, so called Altemative Transportation which is a new form of public transportation that appears in the Brazilian urban context by the mid ninety' s, this work is made by independent or sub-contracted workers, usually organized in cooperatives . It reflects the investigation of new forms of precarious work, unformal which has been expanding in the urban transportation sector. Thus, discusses non regulation of the services sector problem the ways of survival of exc1uded workers from the formal work market mainly afier the capital productive restructure. It has as privileged area of investigation, the sector policy of urban transportation that make field of the main nets of political articulations that define the dynamic of the urban space. It is known that the urban collective transportation allows the access to the production, circulation and general consumption being necessary to the mobility of the resident population, mainly to those with low purchasing capacity. It becomes a field of empirical investigation at the Belem municipal, located at the Amazonic region - north Brazil. The main points dealed on this research start from concrete relations from the daily life of workers that deve1op their activity on the altemative transport mediated with theoretical references needed for understanding and interpretation of the studied reality. The investigation strategies were built from the abstract (theorical knowledge produced for the reality analyze) in concrete by the investigation quantitative-qualitative from this area of urban policy, making up possible the formation of a references chart to the analyses of the studied subject. Rescue his historicity, from characterization of the urban space of the metropolitan region of Belem passing true the forms of organization and urban services performances while essential production and reproduction element of the social relations. Identifies the main individuals that historically have been participating in the construction of the municipality transport policy and the ways of expression of the local political strength relations. Outstand the State paper on the net of established relations near the local power, as well as outstand the importance of social sciences in the understanding of urban policies in the transportation area, trying to bring input to the academicals -scientific debate .The above e1ected and mentioned points in this study are crucial for a critical reflection of the transportation policies. That relation is not given, but historically built at the power relation chart that makes up this unique area of the urban policies

Trabalho, pobreza e caridade: as ações do Padre Ibiapina nos sertões do Nordeste

This work started from an investigation concerning the process of education, moralization and disciplining of the poor in the backlands of the Brazilian Northeast region, in the second half of the 19th century, through the incorporation of the values of productive work. In order to do so, we took as our field of investigation the missions of Father José Antônio Pereira Ibiapina (1806-1883), in which an extensive work was developed, including the construction of twenty two (22) charity houses in the States of Rio Grande do Norte, Paraíba, Pernambuco, Ceará e Piauí, but also of weirs, churches, graveyards, hospitals and so forth. Given the socio-historical character of the research, we adopted qualitative methods of analysis and the following procedures: survey and analysis of documents, statute and internal rules that ordered the workings of the charity houses; biographies on Father Ibiapina and the missions‟ reports, as well as various sorts of publications on the missionary. Our study comprises his 27 year-period of missionary-religious activity (1856-1883), and undertakes an analysis on the topic of poverty, since the medieval Christian take on it until modernity, when it stops representing a value and becomes a problem to be solved through work. The socio-political context in which Ibiapina lived in the Northeast was marked by the consequence of droughts and economic crises in the region. The analysis of the documents indicates that, in the circumstances of political weakness and lack of interest for regional demands by the national political agenda, his missionary actions produced strong effects. Starting from an ethics of valorization of work, which combined modern and traditional elements, his actions set up disciplinary, moralizing and civil educational practices of the poor, founding, simultaneously, a pragmatic religious experience directed at the resolution of the problems caused by poverty. In that sense, we observe that such actions are connected to the broader process of moralization and education of the poor, but the analysis also suggests that their inscription into the social order articulated both forward as well as conservative aspects of the established system

O Trabalho e o labirinto da responsabilidade socioempresarial:a experiência da cidadania empresarial do Banco do Brasil

In the current systemic crisis, economic policy is directed to correct the consequences of the functioning of this metabolism, but within the limits of the capital. From this perspective, decision makers propose trade policies, agricultural and industrial to ensure conditions for economic growth. However, as a dead end, there is failure of the State in giving efficacy to the operation of all segments of the economy, especially given the budget constraint. Public managers are forced to seek external resources, resuming the cycle of political allegiance to the interests of international financial and banking representatives, installed in so-called multilateral. The complex ideological capital comes into play in trying to convince society that the paths taken by governments are inevitable, and that capitalism can be "humanized", even with the realization of the growing inequalities caused by historical irrationalism of the production process of capital . In this sense, emerging concepts that attempt to demonstrate the compatibility of the system to real human needs. This ideological offensive is intended to legitimize the capital. The so-called third sector has a special highlight with the concept of corporate social responsibility. It creates a political environment in which the inevitable mix-up with new illusions offered by and often funding the metabolism of capital in order to perpetuate this system. In this context, political elites, and considerable portions of the academy, embark on "waves of capitalist optimism," while the sociometabolismo capital expands its historical limits, driving forces postponing their collapse, but that cause human suffering and ecological stress. Wars are disseminated to strengthen the deadly war industry and the automobile industry; and devastating the environment of which depends the capital system. In this scenario disassemble, propositions emerge around a "new social pact" in order to minimize the adverse effects of the dynamics of reproduction of capital. The business class is called to exercise its role through the discourse that appeals to social responsibility programs, in order to intervene directly in the "social question". The core of this research is precisely this point. Although there is considerable scholarship on the phenomenon of Social Responsibility and Corporate Citizenship, there is also an evident lack of this approach focused on the banking sector in Brazil. The importance of rentier capital increased ownership of shares in the wealth produced by all of Brazilian society, justifies a sociological research project on Social Responsibility in the domestic financial sector. In this sense, it was decided to perform a dynamic approach to the "Corporate Citizenship" in the banking industry, specifically in the Bank of Brazil. As this is a key institution, is important analyze of the impacts of this strategy fetish of capitalist reproduction, in order to evaluate the social legitimization of rentier capital in Brazil. In this scenario of the abundance of the discourse on social responsibility there exist a progressive impoverishment of professional work in this segment in Brazil. There is a dramatic mismatch between rhetoric and practice because of the trend of deepening vulnerability of the working conditions of the Brazilian bank worker, from the 1990's. In the specific case of the Bank of Brazil, the first initiative of the institution was to conform to the principles of the UNO and the Ethos Institute, aiming to align their domestic policies to this new strategy of domination of capital. The purpose is to place the Bank in the ideological sphere of corporate social responsibility, just as with its partners in the private financial intercapitalist competition. Indeed, in the internal ambit of the Bank of Brazil, there is a policy to adjust its functional segments to the doctrine of Social Corporate Responsibility. The concepts of this doctrine is presented as something inexorable. There are no alternatives. The Bank of Brazil operates in a highly competitive market, the segment featuring the dominance of financial capital accumulation today. For this reason it can not fail to incorporate the technological advances organizational. For employees there is no alternative but to adapt to this new set of ideas proposed by the metabolism of capital

A investigação criminal e a vedação ao anonimato no sistema jurídico brasileiro

The thesis, prepared with basis on deductive reasoning (through the utilization of general concepts of the fundamental rights theory) and on inductive logic (by means of the consideration of particular situations in which the theme has been approached) deals with the criminal investigation and the prohibition of anonymity in the Brazilian law system. The state criminal investigation activity presents not only a substantial constitutional basis, due to the objective dimension of fundamental rights (which imposes an obligation to protect these essential values), but also a formal constitutional basis, arising from the administrative principles of rule of law, morality and efficiency, referred to in article 37 of the Constitution. The criminal investigation, however, is not an unlimited pursuit, being restrained by the duty to consider fundamental rights that oppose to its realization. One of the limits of the state investigation activity, in the Brazilian law system, is the prohibition of anonymity, referred to in article 5°, IV, of the Constitution. This prohibition is a direct constitutional restriction to the freedom of expression that aims to ensure the credibility of the diffusion of ideas and prevent the abusive exercise of this fundamental right, which could harm both persons and the state, with no possibility of punishment to the offending party. Generally, based on this prohibition, it is affirmed that a criminal investigation cannot begin and progress founded on anonymous communication of crimes. Informations about crimes to the investigative authorities require the correct identification of the stakeholders. Therefore, it is sustained that the prohibition of anonymity also comprehends the prohibition of utilization of pseudonyms and heteronyms. The main purpose of this essay is to recognize the limits and possibilities in starting and conducting criminal investigations based on communication of crimes made by unidentified persons, behind the veil of anonymity or hidden by pseudonyms or heteronyms. Although the prohibition of article 5°, IV, of the Constitution is not submitted to direct or indirect constitutional restrictions, this impediment can be object of mitigation in certain cases, in attention to the constitutional values that support state investigation. The pertinence analysis of the restrictions to the constitutional anonymity prohibition must consider the proportionality, integrated by the partial elements of adequacy, necessity and strict sense proportionality. The criminal investigation is a means to achieve a purpose, the protection of fundamental rights, because the disclosure of facts, through the investigatory activity, gives rise to the accomplishment of measures in order to prevent or punish the violations eventually verified. So, the start and the development of the state criminal investigation activity, based on a crime communication carried out by an unidentified person, will depend on the demonstration that the setting up and continuity of an investigation procedure, in each case, are an adequate, necessary and (in a strict sense) proportional means to the protection of fundamental rights

Alfabetizar letrando: investigação-ação fundada nas necessidades de formação docente

The accomplished researches in the education field focus on the importance of the accomplishment of actions involved in the analysis of the needs to graduate teachers as a way to adequate to socialcultural changing that require more and more a creative activity to prepare teachers in their graduation perspective. The worry with a fail at school linked to public school students lead us to make this thesis which goals are: investigate the needs of the graduation of teachers at public Elementary Schools concerning to the subjacent knowledge to the development of a pedagogic practice of alphabetizing with literacy and (re)create, with some teachers as active participants in the researches, knowledge regarding the process of alphabetization with literacy , based on the graduation of teachers. The study was accomplished in a municipal Elementary School in the Ceará-Mirim city, located in the state of Rio Grande do Norte, which offers both I and II levels of the Elementary School, 7 teachers and the principal of the school were subjects of our researches. The starting point was the needs of the graduation as subject phenomena, socially created and that allow people to be aware of the goals of a graduation. The investigative broach is qualitative, whose fundamental purpose is the understanding of the meanings, symbols, values and intentions of the mankind actions, as regards to other humanbeing and the contexts in which they interact. Within this context, we chose the investigation-action for we consider this kind of research a place for investigation and professional graduation, in which teachers and the researcher herself assume responsibility of problematizing, build the needs of graduation and think about their practices. As proceedings to create and analyze data, we developed participant observations during the activities in classroom; semi-structured interviews (individual and in groups) with teachers and the principal; analysis of documents and meetings at school for reflexive studies that enabled us to gather data in a pyramidal panoramic view and analyze the contents. The research revealed that the analysis of necessities to graduate teachers is a resource able to contribute to the planning of projects of keeping on graduating more properly, and thus create a critical and reflexive identity for teachers. This way, it was possible the graduation necessities could be revealed and also the knowledge of teachers as regards to alphabetization inserted in a perspective of literacy. Nowadays, conceptualized needs upon difficulties of teachers, there is a tendency to translate them into theorization of problems, without application to these knowledge of teachers, as well as their wishes for changing, especially when those needs are built to analyze and consider concrete practices. Therefore, the graduation experiences have enabled the abandon of a mechanical broach for teaching reading and writing. It has also lead teachers to assume a posture of providing their students the understanding about the reading and writing processes and their functions as social instruments. The graduation theme contents allowed the knowledge to conceive reading and writing in new perspectives, according to their social functions, so that they can improve the education with literacy quality. This theoretical construction has enabled us to understand and consider the necessities of the graduation as progressive process, and has given us the possibility of re-think our own learning processes at the university and review the pedagogical practices of public school teachers. Our conclusion is that once teachers consider their own graduation needs, it contributes to change their concepts and practices in education and literacy, even though there used to be many difficulties in their graduation and organization of the pedagogical work

Análise da contribuição de estagiários remunerados na força de trabalho em enfermagem

The present study analyses non obligatory and remunerated traineeships in nursing, as a contribution to work process in health and learning of students at nursing technician courses. It objectives to examine the contribution of medium level nursing students on scholarships at a teaching hospital s work force, at Natal/RN. It s a quantitative/qualitative, that uses descriptive statistics and analysis fulfilled with categories that emerged from research, through a dialog between the studied authors in the theoretical reference of nowadays work process, work force, non obligatory and remunerated traineeships, and night shifts. The collaborators of this research were 105 (73,43%) nursing technicians, medium level students on scholarships that fulfill remunerated traineeships at the hospital. The feminine gender was a major part of the collaborators, with 90 (85,70%), in which medium age was 29,71 years, 62 (59,00%) single, 57 (54,30%) don t have kids, 100 (95,23%) students on scholarships with complete medium level, 78,10% with professional experience before their insertion at the remunerated traineeships, 73 (69,50%) referred to enjoy the area, reason for the nursing technician course choice. About the technician course conclusion, 83 (79,00%) affirmed that happened between 2005 and 2008, and about traineeships time in the institution, 38 (36,20%) have between one and six months. About learning, 74 (70,50%) referred to learn with the nursing technicians and all fulfilled specialized courses, or grade up to bond with the school and be able to be trainees. These courses were considered low quality ones, what justifies the number of 54 (51,40%) students with scholarships that said their performance in studies is good and 75 (71,40%) are able to join it with the traineeships without problems. About remuneration as scholarship, 71 (67,60%) referred that helped to keep up with the studies, because this amount has specially this purpose, paying studies. About nonobligatory traineeships, the ABEn-RN affirmed that there s no following process to this traineeship mode, as long as there was never this concern, because obrigatory traineeships demand a lot of the efforts in the meetings. And COREN-RN doesn t supervise this way of contract. The present research observed that there is, in fact, a contribution of medium level nursing students on scholarships work force on the researched institution. Resigned to work circumstances established by the institution, representing the lack of human resources, materials, work conditions, and work insertion in night shifts, it s possible to affirm that the situation is irregular about the students on scholarships, besides the determinant risk factor to their lives and health. In addition to it, the students on scholarships, in order to maintain the quality of trainee in the institution, are obligated to fulfill courses to grade up, or specialized courses in nursing technician, at schools referred as bad quality ones

Contribuições da investigação em sala de aula para uma aprendizagem das secções cônicas com significado

In this work, the didactical possibilities of investigation use in classroom, through an experience with high school students from Federal Center of Technological Education of Paraíba, as well as the study of conic sections were analysed. In order to fulfill our goals the theoretical conceptions concerning the meaninful learning in conection with the investigation of mathematics history were taken into account. The classroom research occurred by means of activities which encouraged the learner to investigate his own concepts on the conic sections. The results of the proposed activities showed the effectiveness and the efficiency of such a methodology as regards the making up of the required knowledge. They also reveal that the investigation in the classroom guides the ones involved, in this process, to have a wider look at the origins, the methods used and the several representations presented by mathematics that certainly lead, specially the students, to a meaninful learning

Uma investigação histórica sobre os logaritmos com sugestões didáticas para a sala de aula

This study was conducted from a preliminary research to identify the conceptual and didactic approach to the logarithms given in the main textbooks adopted by the Mathematics teachers in state schools in the School of Natal, in Rio Grande do Norte. I carried out an historical investigation of the logarithms in order to reorient the math teacher to improve its educational approach this subject in the classroom. Based on the research approach I adopted a model of the log based on three concepts: the arithmetic, the geometric and algebraic-functional. The main objective of this work is to redirect the teacher for a broad and significant understanding of the content in order to overcome their difficulties in the classroom and thus realize an education that can reach the students learning. The investigative study indicated the possibility of addressing the logarithms in the classroom so transversalizante and interdisciplinary. In this regard, I point to some practical applications of this matter are fundamental in the study of natural phenomena as earthquakes, population growth, among others. These practical applications are connected, approximately, Basic Problematization Units (BPUs) to be used in the classroom. In closing, I offer some activities that helped teachers to understand and clarify the meaningful study of this topic in their teaching practice
