Letramento em química, educação planetária e inclusão social

From the different conceptions on scientific and technology literacy (STL), and reflections on globalization and social inclusion, this paper points out the responsibility of the chemists in social actions by their associations for supporting political actions to improving the quality of life, and to protecting the environment by sustainable development for changing the modern society. Supporting ideas for equity within the society between the nations, and giving examples from approaching of socioscientific issues of the textbook "Chemistry and Society", it demonstrated the role of the teachers and the chemistry professionals to realize the STL of the people in the planetary perspective.

O espaço da prática de ensino e do estágio curricular nos cursos de formação de professores de química das ies públicas paulistas

The literature presents a new understanding of the teaching practice and the supervised internship.Mutual interaction between them is expected one providing subsidies to the other.The present article shows the conceptions prevailing at the São Paulo state universities regarding these activities.Students,when interviewed, report difficulties in dealing with classroom situations. It is possible to observe that chemists wish to prepare new chemists deviating from the objectives of a Chemistry course leading to teaching credentials .

Proceso de transformación de las concepciones del profesorado sobre la resolución de problemas matemáticos

The aim of this study is to analyze the transformation of Primary School teachers’ conceptions about mathematical problem solving. We performed a study with 18 teachers from three public schools: in each class (from 1º to 6º) there were two interventions, and we were interviewed teachers before and after them. The results have show identified changes in: 1) teacher’s expectations about students’ abilities; classroom management; perception of diversity; mathematical strategies used by students; communication in the classroom; causes of the problems encountered; and relevance process of problem solving in mathematics teaching. The transformation of teachers’ conceptions is due to the following factors: a) awareness of the practice; b) systematic reflection; c) the contrast between different ways to work solving problems in math class

Concepções e ações de formadores de professores de química sobre o estágio supervisionado: propostas brasileiras e portuguesas

The purpose of this paper is to investigate lecturers'actions and conceptions about pre-service teaching practices in chemistry. In this sense, it takes into account several theoretical references concerned with teacher education, which support the qualitative analysis of 18 interviews, gathered with 14 brazilian and 4 portuguese lecturers. Results reveal that the pre-service teaching practices in chemistry have been performed far from a technical approach, showing a paradigmatic rupture and presenting another logic related with teacher education in chemistry, which have improved the comprehension of the teachers' real practices, since these have been shaped by complex and unprescribed factors.

Concepções sobre currículo de formadores de professores: o curso de licenciatura em Química do Instituto de Química da Universidade Federal do Rio de Janeiro

In this paper, we discussed the conceptions of curriculum of teachers' trainers from de course of Chemistry from de Chemistry Institute and from the Education School of the Federal University of Rio de Janeiro. We understand that the curriculum results from a social construction, so, we intent to comprehend how happen the constitution of the course's curriculum, based on documents and interviews with the subjects of the research. The study showed that there were competitions for status, resources and territories between the Chemistry Institute and the Education School when the course was created, as well as there were internal competitions in the creation of the disciplines depending on the department of origin of the teachers.

Noções dos futuros profissionais da Química. eixo I: liberdades e demandas da pesquisa

During the schooling process, images are constructed about research and researcher activities. Based on that, a questionnaire has been structured based on three thematic axes that tend to represent some of the discussions about the translations that integrate the scientific activity collectively: freedom and demands from research, academia as a mediator and science disclosure. The objective of the instrument was to map some notions from entrants to the graduation course in Chemistry in the metropolitan region of Porto Alegre about what, based on the contributions by Bruno Latour, was called vascularizations of research.

O trabalho experimental no ensino de Química

This article deals with conceptions of the experimental work in the Chemistry teaching, developed among teachers and students. The research was carried out using qualitative methodology, based on Gaston Bachelard's thoughts. The results showed dispersion of conceptions among both students and teachers. This dispersion, interpreted as a profile of conceptions, was discussed based on the notions of Bachelard's epistemological profile and Mortimer's conceptual profile. This work points out the need to rethinking and finding new directions for experimental activities in the training courses for Chemistry teachers, in order to meet Chemistry educators' social goals.

CONHECIMENTO PEDAGÓGICO E CONHECIMENTO QUÍMICO NA FORMAÇÃO DE PROFESSORES: A CONSTRUÇÃO DA IDENTIDADE DOCENTE

This paper presents results of a content analysis of the formative professional profile of undergraduates within the context of Brazil's expansion of its federal education system and implementing of teacher training policies. The analysis focuses on the conceptions of undergraduates regarding elements of their initial training and professional perspectives, as recorded in narratives, interviews, and questionnaires. Based on the relationships identified between the recorded content and the Educational Course Project, we identified three categories of analysis that point to tensions generated during the professional development of chemistry teachers: 1) The relationship between pedagogical knowledge and chemical knowledge; 2) the conceptual aspects of science education, as represented by the different ways that students understand the "ionization process"; and 3) teaching identity, including the elements indicative of the identity construction of future teachers. The results indicate that the educational and professional profile of undergraduates is marked by a particular tension between chemical content knowledge and pedagogical content, as well as a lack of objectivity and focus on the course's original intent. This situation has produced a multifaceted training context in which there is confusion regarding aspects relating to the licensing, teaching modalities, and preparation of the chemistry education professional.

Virkavastuu. Määräaikainen virantoimituksesta erottaminen rajavartiomiehen, ammattisotilaan ja poliisin erityisenä kurinpitorangaistuksena.

Tutkielman tavoitteena on oikeudellisten lähteiden systematisoinnilla tuottaa johdonmukainen kuvaus poliisin, rajavartiomiehen sekä ammattisotilaan virkavelvollisuuksista, oikeudellisesta vastuusta ja virkarikosten rangaistavuudesta. Päähuomio kohdistuu virkamiehen määräaikaiseen virantoimituksesta erottamiseen. Oikeudellisella argumentaatiolla pyritään esittämään lainmukainen ja hyväksyttävä tulkintakannanotto siihen, miten kyseistä säädöstä tulisi tulkita. Tutkimusmetodi työssä on oikeusdogmatiikka. Ensisijaisena aineistona tutkielmassa on voimassa oleva lainsäädäntö valmisteluaineistoineen. Toissijaisina lähteinä käytetään kirjallisuutta, viranomaisten kurinpitopäätöksiä ja haastatteluja. Määräaikainen erottaminen voidaan määrätä virkamiehelle, joka toimii vastoin virkavelvollisuuksiaan tai laiminlyö niitä. Säädös on tulkittavissa laajentavasti siten, että myös muut kuin selkeästi viranomaisen valvontavastuulle kuuluvat teot voidaan katsoa virkatehtävien vastaiseksi. Erityisen käyttäytymisvelvoitteen johdosta menettely on rangaistavaa myös vapaa-ajalla. Määräaikainen erottaminen sijoittuu rangaistusasteikossa varoituksen ja irtisanomisen väliin. Rangaistus ei edellytä erityisen painavia perusteita, joita vaaditaan virkamiehen irtisanomiseen. Uuden säädöksen myötä irtisanomisten määrä on vähentynyt Rajavartiolaitoksessa. Säädöksestä on muotoutunut kurinpidollinen lisärangaistus, joka on määrätty virkamiehelle hallinnollisella päätöksellä yleensä rikostuomion jälkeen. Säädös on kuitenkin tarkoitettu ja se mahdollistaa myös puuttumisen varsinaisten virkatehtävien laiminlyönteihin. Lainsäädännön selkeyttämiseksi määräaikaisen erottamisen säädös tulisi poistaa eri viranomaisten erityislainsäädännöstä ja liittää suoraan virkamieslakiin. Säädöksen soveltaminen tulisi ulottaa koskemaan myös muita virkamiehiä, jotka palvelevat kyseisissä viranomaisissa. Tutkimuksen kohteena oleva virkamiesryhmä alistuu virkamiesoikeudessa blankkorangaistusuhan alle. Virkamiehen on vaikea hahmottaa kaikkea rangaistavaa toimintaa, ja virantoimittamisvelvollisuus on usein täsmentymätön ja tulkinnanvarainen. Kokonaisharkinnassa korostuvat myös muut kuin oikeudelliset lähteet (esimerkiksi moraalikäsitykset, etiikka, ohjeet, virkamiehen elämäntilanne). Sotilaiden ja poliisin oikeudenhoito poikkeaa monilta osin muiden virkamiesten oikeudenhoitomenettelystä. Rajavartiolaitoksessa sotilasoikeudenhoidon määräykset ja ohjeet ovat selkeästi puutteelliset. Rajavartiolaitoksen tehtäväkentän ja toimivaltuudet huomioiden tulisi kurinpito- ja virkarikosten tutkinnoissa lähentyä poliisin mallia sekä hyödyntää rikostorjuntahenkilöstön ammattitaitoa oman henkilökunnan esitutkinnoissa. Erityisen turvallisuusviranomaisten virkarikoksiin erikoistuneen tutkintaorganisaation perustaminen voisi tehostaa ja parantaa esitutkintojen tasoa sekä lisätä oikeusvarmuutta.

Liikkuvien työkoneiden valmistettavuuden kehittäminen teollisessa liiketoimintaverkostossa

Diplomityön tavoitteena oli kehittää Pilomac – konsernin päähankkijayrityksien tuotteiden valmistettavuutta yhteistyössä yrityksien suunnitteluosastojen ja teräsrakenteita valmistavien toimittajayrityksien kanssa. Päähankkija-yritysten, Junttan Oy:n ja Logset Oy:n, osavalmistusten ulkoistamisen myötä toimittajasuhteet ovat vähitellen muuttumassa verkostomaiseen toimintatapaan. Täten on tärkeää muuttaa ja kehittää tuotteiden valmistettavuuden mahdollistavat toimintamallit vastaamaan uutta toimintatapaa. Keskeinen perusmenetelmä valmistettavuuden huomioimisessa on suunnittelun ja valmistuksen välisen tuotekehitysyhteistyön syventäminen rinnakkaissuunnitteluksi, (CE). Verkostokumppaneiden välinen yhteistyö perustuu avoimuuteen, luottamukseen ja molempia osapuolia hyödyttävään jatkuvaan kehitystyöhön. Verkostomainen toimintatapa mahdollistaa luontevasti tuotteen suunnittelu- ja kehitysvastuiden jaottelun yritysten ydinosaamisen mukaan. Onnistuneen työnjaon myötä resurssit lisääntyvät ja valmistusteknologiat, suunnittelu ja laatu kehittyvät ja monipuolistuvat. Työn aihetta tutkittiin soveltavassa osassa benchmarkingin, nykytilakuvauksien sekä toimittajaverkoston analysoinnin avulla. Toimittajaverkoston analysointi tehtiin laajan verkostokumppanikyselyn avulla, josta selvisi Junttan Oy:n toimittajaverkoston resurssit ja kyvykkyys. Kyselyssä selvitettiin myös nykyisten toimittajien näkemyksiä valmistettavuuden kehittämisestä, kumppaneille asetettavista yhteistyövaatimuksista sekä näiden toimintamallien vaikutuksista tuotteiden kilpailukyvyn parantumiseen. Työn tuloksena selvisivät osa-alueet, joita Junttan Oy:n kannattaa hyödyntää tulevaisuudessa enemmän sekä toimintamallit, jotka mahdollistavat tuotteiden valmistettavuuden jatkuvan kehittämisen.

Kielikeskuksissa toimivien kieltenopettajien käsityksiä ja kokemuksia massayliopiston luomista haasteista

Challenges of mass university conceived and experienced by university language centre language teachers The massification of the university involved not only an expansion but also a transition from one period to another, from elite higher education to mass higher education. Massification cannot be viewed as expansion and structural change but it has to be viewed in a context of a number of changes involving universities, state, economy, society and culture as well as science, technology, education and research. In the Finnish academic context, massification is often associated with negative development and it may be used as an excuse for poor teaching. The objective of the present study is to find out how the mass context is manifested in the work of university language centre language teachers. The data were collected by means of semi-structured questionnaires from 32 language teachers working at language centres at the universities of Helsinki, Jyväskylä, Tampere and Turku in Finland. Both Finnish and native speakers, 6 male and 26 female teachers, were included. All the teachers in the study had taught more than 10 years. The data were complemented by interviews of four teachers and email data from one teacher. Phenomenographic analysis of the informants’ conceptions enabled a description of their experiences of students at a mass university, conceptions of teaching and learning and of issues related to work health. Some conceptions were consonant with earlier results. The conceptions revealed differences between two teacher groups, teachers of subject-specific language, or language for specific purposes (LSP), and teachers of elementary and advanced language courses (general language teachers). For the first, the conceptions of the investigated teachers provided a picture of the students as a member of a mass university. The students were seen as customers who demanded special services to facilitate their studies or were selective about the contents of the course. The finding that appeared only in the LSP teachers’ data was the unengaged attitude towards language study, which appeared as mere hunt for credits. On the other hand, the students were also seen as language learning individuals, but a clear picture of a truly interested language learner was evident in the data of general language teachers. The teachers’ conceptions of teaching and learning revealed a picture of experienced teachers with a long background of teaching, reflecting experiences from different time periods and influences from their own education and illustrating the increasing problems with organizing individual tutoring due to large, heterogeneous groups. It seemed, however, that in spite of the large student groups, general language teachers were able to support the students’ learning processes and to use learner-centred methods, whereas LSP teachers were frequently compelled to resort to knowledge transmission type of teaching. The conditions of the mass university were clearly manifested in the respondents’ conceptions about work satisfaction: there were a number of factors related to administration, teaching arrangements and the status of the language centres that were likely to add to the teachers’ work stress, whereas traditional characteristics of academic work were viewed as promoting work satisfaction. On the basis of the teachers’ conceptions, it is safe to assume that academic mass context and students’ orientations have an effect on the teacher’s approach to teaching, while there is no unequivocal association between mass university teaching and poor teaching.

Prolegomenon for an ethics of visibility in Hannah Arendt

This paper aims to discuss the Arendtian notions of appearance and perception in order to promote a displacement of those conceptions from the generally associated domain of passive apprehension of the faculty of knowledge towards the domain of a praxiology of action and language, based on an active perception. Arendt's appropriations on the Heideggerian "to take one's place" (sich hin-stellen) will be discussed, as well as the Augustinian "finding oneself in the world" (diligere). A twofold disposition of appearance will be distinguished: producing and position, whose transposed to the Arendtian notion of world correspond, respectively, to fabrication (poiesis) of the world, man's objective in-between space, and to action (praxis) in the world, man's subjective in-between space. Those conceptual replacements, in a broad sense, uphold a closer imbrication between the activities of the mind and acting, stricto sensu, and consequently, foment not only the valorization of the public space, but the visibility of our acts and deeds as well, calling out the dignity of appearance in ethics.

Parallella, dynamiska representationer i gymnasiefysiken : implementering av ett interaktivt datorverktyg i didaktiska situationer och uppfattning av effektivt lärande

The computer is a useful tool in the teaching of upper secondary school physics, and should not have a subordinate role in students' learning process. However, computers and computer-based tools are often not available when they could serve their purpose best in the ongoing teaching. Another problem is the fact that commercially available tools are not usable in the way the teacher wants. The aim of this thesis was to try out a novel teaching scenario in a complicated subject in physics, electrodynamics. The didactic engineering of the thesis consisted of developing a computer-based simulation and training material, implementing the tool in physics teaching and investigating its effectiveness in the learning process. The design-based research method, didactic engineering (Artigue, 1994), which is based on the theoryof didactical situations (Brousseau, 1997), was used as a frame of reference for the design of this type of teaching product. In designing the simulation tool a general spreadsheet program was used. The design was based on parallel, dynamic representations of the physics behind the function of an AC series circuit in both graphical and numerical form. The tool, which was furnished with possibilities to control the representations in an interactive way, was hypothesized to activate the students and promote the effectiveness of their learning. An effect variable was constructed in order to measure the students' and teachers' conceptions of learning effectiveness. The empirical study was twofold. Twelve physics students, who attended a course in electrodynamics in an upper secondary school, participated in a class experiment with the computer-based tool implemented in three modes of didactical situations: practice, concept introduction and assessment. The main goal of the didactical situations was to have students solve problems and study the function of AC series circuits, taking responsibility for theirown learning process. In the teacher study eighteen Swedish speaking physics teachers evaluated the didactic potential of the computer-based tool and the accompanying paper-based material without using them in their physics teaching. Quantitative and qualitative data were collected using questionnaires, observations and interviews. The result of the studies showed that both the group of students and the teachers had generally positive conceptions of learning effectiveness. The students' conceptions were more positive in the practice situation than in the concept introduction situation, a setting that was more explorative. However, it turned out that the students' conceptions were also positive in the more complex assessment situation. This had not been hypothesized. A deeper analysis of data from observations and interviews showed that one of the students in each pair was more active than the other, taking more initiative and more responsibilityfor the student-student and student-computer interaction. These active studentshad strong, positive conceptions of learning effectiveness in each of the threedidactical situations. The group of less active students had a weak but positive conception in the first iv two situations, but a negative conception in the assessment situation, thus corroborating the hypothesis ad hoc. The teacher study revealed that computers were seldom used in physics teaching and that computer programs were in short supply. The use of a computer was considered time-consuming. As long as physics teaching with computer-based tools has to take place in special computer rooms, the use of such tools will remain limited. The affordance is enhanced when the physical dimensions as well as the performance of the computer are optimised. As a consequence, the computer then becomes a real learning tool for each pair of students, smoothly integrated into the ongoing teaching in the same space where teaching normally takes place. With more interactive support from the teacher, the computer-based parallel, dynamic representations will be efficient in promoting the learning process of the students with focus on qualitative reasoning - an often neglected part of the learning process of the students in upper secondary school physics.

Images of imagination : an aesthetic approach to education

Visual art practice has generally been described as a lonely affair, thinking about what an artist has experienced in the outside world. This study is an inquiry into a visual art practice of another kind: the relational one. The research purpose is twofold. The first purpose is to shed light on a visual artist’s conceptions of art, education and scholarship. The second purpose is to by reasoning on imagination and a rhizomatic formation interpret the relations created between art, multimodality and literacy learning as an aesthetic approach to education. By inquiry into a specific collaborated long-term art practice, the study conveys how the meaning making elements of an arts based learning practice gradually transform an artist’s and a teacher’s concepts of art education to an aesthetic approach to education. In the art practice examined the typical Finnish rye bread and a poem have represented a cultural theme that has been elaborated through art conventions. The poem and the rye bread have in the art practice been articulated as cultural representations of as well as symbolic projections on the Swedishspeaking minority culture in Finland. The study connects art informed inquiry to a hermeneutic research rationale where the research reasoning is generated through a rhizomatic alliance between empiric data and theories. The reasoning is constructed as an interpretation pattern that expands throughout the study. The study arguments that the rhizome as an aesthetic formation can be appropriate to refer to when articulating arts based meaning making and when creating arts based educational strategies, dialogues, aesthetic learning and multimodal literacy in education. The study investigates an aesthetic approach to research in education, which means that the art practice surveyed is interpreted through articulation appropriate to poetic aspects of art, education and research.

Musikaliska möten man minns : om musikundervisningen i årskurserna sju till nio som en arena för starka musikpplevelser

Earlier research has shown that strong experiences related to music (SEM) can occur in very different contexts and take on many different forms. Experiences like these seem significant and have among other things reportedly had an affect on the individual's continuing relationship towards music, which makes them interesting from a pedagogical point of view. Formal teaching situations, though, are under-represented in studies where people have been asked to describe strong experiences that they have had in connection with music. The purpose of my thesis is to investigate what SEM may mean to pupils and teachers in lower secondary school (grades 7-9), and to inquire more deeply into the potential "space" for such experiences within school music education. On a comprehensive level my ambition is to deepen the understanding for SEM as a possible element in pedagogical situations. Three empirical perspectives are employed: pupil-, teacher- and curriculum perspectives. The pupil perspective involved an analysis of written accounts of 166 fifteen-year-olds, describing own strong experiences. The teacher perspective involved studying 28 music teachers' conceptions of the purpose of teaching music in school as well as their understanding about strong music experiences in school context. Further, the teachers' descriptions of SEM that they have had themselves were analysed. The curriculum perspective is reflected through a study of how music experience was represented in 24 local and 2 national curriculum texts for music. Grounded in a phenomenological-hermeneutical perspective the material have been analyzed both qualitatively and quantitatively. The result points towards the fact that the music education in school has the potential to become an arena for SEM and that this can happen in relation to a multitude of activities and genres and take on many different expressions. Only one pupil referred to a musical encounter in the classroom environment; all other experiences that occurred inside the frame of school activity had taken place in other arenas (the school hall, public concert halls, and so on). However, more than 98 % of the descriptions concerned musical encounters in leisure time contexts. The significance of SEM is further clarified by narrative constructions. SEM as a conception does not occur on the curriculum level; however the analyze revealed a number of interesting "openings" which are illustrated. Even though all teachers displayed a fundamentally positive attitude towards the idea of regarding SEM as a feature of formal musical learning, it became clear that many teachers never had approached this theme from a pedagogical point of view before. Still, they proved to have an evident "familiarity" towards the phenomenon based on their own experiences of receptive and performative musical encounter. The possible space for strong musical experiences within school music education is specified through a detailed illustration of six specific themes derived from the reasoning of the teachers. Furthermore, this is described through a mapping of the potential experiencing zone, constructed from the teachers descriptions of educational aims.
