The aim of this study is to investigate the views of preservice science teachers on science-technology-society, STS, issue. A total of 176 preservice science teachers participated in the study. A 26-item &ldquo / Views on Science-Technology-Society (VOSTS)&rdquo / instrument, translated and adapted into Turkish, were utilized to assess participants&rsquo / views on STS. The VOSTS (Aikenhead, Ryan and Fleming, 1989) is a pool of 114 empirically developed multiple-choice items with nine categories. In order to understand participants&rsquo / views on STS in depth, semi-structured interviews were also conducted by 9 volunteer preservice science teachers. The results gave a colorful picture of the views of preservice science teachers on science-technology-society issue. The analysis revealed that preservice science teachers often confuse the definitions of technology with science. Most of the participants of the study had specific views about the reasons of doing scientific researches in their country, for example, to be independent from other countries, to get financial profit. Results displayed a consensus on the possible positive effects of upbringing and the importance of education given to high school students. According to the data obtained from the present study, respondents possess varied views about the influences of society on science and technology. While preservice science teachers claiming that scientists could break the rules of science, they also claimed scientists as objective in their study. On the other hand, participants supported the view that scientists&rsquo / concern on all the effects of their experiments. Preservice science teachers advocated also that technological developments can be controlled by citizens.

The purpose of this investigation was to determine the extent to which multicultural science education, including indigenous knowledge representations, had been infused within the content of high school biology textbooks. The study evaluated the textbook as an instructional tool and framework for multicultural science education instruction by comparing the mainstream content to indigenous knowledge perspectives portrayed in the student and teacher editions of 34 textbooks adopted in Florida within the last four adoption cycles occurring from 1990 to 2006. The investigation involved a content analysis framed from a mixed methods approach. Emphasis was placed, in consideration of the research questions and practicality of interpreting text with the potential for multiple meanings, within qualitative methods. The investigation incorporated five strategies to assess the extent of multicultural content: 1) calculation of frequency of indigenous representations through the use of a tally; 2) assessment of content in the teacher editions by coding the degree of incorporation of multicultural content; 3) development of an archaeology of statements to determine the ways in which indigenous representations were incorporated into the content; 4) use of the Evaluation Coefficient Analysis (ECO) to determine extent of multicultural terminologies within content; and 5) analysis of visuals and illustrations to gauge percentages of depictions of minority groups. Results indicated no solid trend in an increase of inclusion of multicultural content over the last four adoption cycles. Efforts at most reduced the inclusion of indigenous representations and other multicultural content to the level of the teacher edition distributed among the teacher-interleafed pages or as annotations in the margins. Degree of support of multicultural content to the specific goals and objectives remained limited across all four of the adoption cycles represented in the study. Emphasis on standardized testing appeared in the six textbooks representing the most recent adoption cycle. Recommendations included increased efforts to identify quality of content by including input from scholars in the field of multicultural education as well as indigenous peoples in the creation of textbook content. Recommendations also included further clarification of the definition of science within multicultural science education frameworks, indigenous knowledge as compared to Western science and pseudoscience, and scientific literacy as a central focus to a multicultural science education meant to address the needs of an increasingly diverse student population and prime-age workforce.

This descriptive case study focuses on how Technology teachers interpret and enact the interrelationship of the Technology-Society-Environment (TSE) theme with the Technological Process and Skills (TPS) and Technological Knowledge and Understanding (TKU) curriculum themes of the South African school subject, Technology. Science and technology have influenced society in the twentieth and twenty-first Century to a considerable extent. A critical study of this group of related influences is termed Science- Technology-Society and addresses socially relevant topics that encourage critical and high level thinking skills, problem-solving and decision making capacity. These issues are included in the Technology curriculum as the TSE theme. Using the TSE theme in teaching would have the potential to make the curriculum more relevant and learning more meaningful as it provides scope for teachers to engage learners to construct knowledge at a critical level in different real life contexts. This study investigated the relationship between teachers’ understanding of the interrelationship of TSE with Technological Process and Skills (TPS) and Technological Knowledge and Understanding (TKU) themes and the extent to which the unique features and scope for teaching Technology are met. The study was set in Bohlabela district of the province of Mpumalanga, in South Africa and implemented between August 2011 and April 2012. Four teachers of different schools and circuits were interviewed, three were observed during teaching, their lessons, work schedules and learners’ workbooks and project portfolios were analysed. A novel combination of an adaptation of the Ben-Peretz scheme of curriculum document analysis and Rogan and Grayson construct of implementation frame was used in the analysis of the information obtained through documents and observations. The study established that only in exceptional cases teachers use learner centred approaches that allow the integration of the TSE theme with the process (TPS) and knowledge (TKU) themes. Evidence was found that while teachers planned such integration, learners themselves do not show any examples of such integration in their workbooks. Teachers have difficulties with specific knowledge areas of the Technology curriculum, in spite of formal adequate basic training in the subject. Teachers ascribe these difficulties to resource limitations, the absence of specific technology training and inadequate support by teacher support personnel. It is recommended that teacher support groups be established, and that the Department of Education develop specific curriculum materials and train teachers in the interpretation and enactment of the documents. / Dissertation (MEd)--University of Pretoria, 2012. / gm2014 / Science, Mathematics and Technology Education / unrestricted

Science teaching according to STS (Science-Technology-Society) education comes out as an approach that aims to integrate scientific, technological and social themes in a given content. This approach stimulates students to develop skills that enhance their ability to play their role in society in an active and mindful manner, and hence contributes to the rise of a larger number of scientifically and technologically literate citizens. In that regard, the main objective of the present study is to analyze academic studies master s and doctoral theses produced between 1992 and 2009 that have focused on the STS education field, seeking to identify STS education perspectives pointed out in those studies during that time span. The secondary objectives of this study are: (i) to identify master s and doctoral theses in Education, Science and Mathematics Teaching or related graduate programs of Brazilian and Portuguese federal or state universities, all of the works dating from 1992 to 2009 and investigating approaches related to STS education; and (ii) to characterize the thematic focuses, methodological and STS approaches in those theses. Therefore, this is a state of knowledge research conducted according to a theoretical, bibliographical, and quantitative-qualitative approach, for which the Qualitative Content Analysis method was used. Among the most relevant results, it has been found that 14% of the investigated Brazilian theses were directed towards the college level, whereas none of the Portuguese theses had the same intent. On the other hand, 79% of the Portuguese theses were aimed to the first years of school, whereas only 21% of the Brazilian theses were devoted to that education level. Analyses were also carried out in order to identify and discuss which STS approaches and/or perspectives are present in doctoral theses finished at both Brazilian and Portuguese universities. Such analyses have indicated that the main STS education model observed in the theses is Logical reasoning (40% of the theses, i.e., 10 out of 24 theses), followed by Sociocultural (39% of the theses, i.e., 9 out of 24 theses), Historical (3 theses), Socio-ecojustice (2 theses), and Application/Design (1 thesis). In general, the analyzes revealed that, even though there is a consensus among the academic community involved with studies on STS education, different interpretations of STS-based Science education have been emerging along decades, which reveals a field under construction and reconstruction. / Atualmente, a Ciência e a Tecnologia, com seus desenvolvimentos e influências nas dimensões humana, social, cultural e econômica, passaram a ter suas naturezas, suas potencialidades e seus limites como objetos de debate. Diante disso, o ensino de Ciências seguindo a orientação e educação CTS (Ciência-Tecnologia-Sociedade) aponta para objetivos que visam estabelecer relações entre os conhecimentos científicos, tecnológicos e sociais no desenvolvimento de conteúdos escolares. O que se espera com esse ensino é contribuir para a geração de maior número de cidadãos científica e tecnologicamente alfabetizados na medida em que os estudantes são estimulados ao desenvolvimento de conhecimentos e competências que lhes possibilitem assumir um papel consciente e ativo na sociedade. Esta pesquisa se insere nessa temática e tem como objetivo geral analisar trabalhos acadêmicos teses e dissertações produzidos no campo da educação CTS, no período de 1992 a 2009, procurando identificar as perspectivas da Educação CTS apontadas nesses trabalhos ao longo desse período. Os objetivos específicos da pesquisa são: (i) identificar teses e dissertações defendidas, no período de 1992 a 2009, nos programas de pós-graduação das áreas de Educação, de Ensino de Ciências e Matemática e correlatos de universidades estaduais e federais brasileiras e de universidades portuguesas, no âmbito do ensino que tem como referência à educação CTS; (ii) caracterizar os focos temáticos, as abordagens metodológicas e as abordagens CTS adotadas nessas investigações. Trata-se de uma pesquisa do tipo estado do conhecimento que foi conduzida segundo uma abordagem quantiqualitativa de natureza teórico-bibliográfica, na qual se utilizou a metodologia de Análise de Conteúdo. Entre os resultados do estudo comparativo destaca-se que nas pesquisas brasileiras 14% das investigações têm como foco o nível de ensino superior, enquanto não foi encontrada investigação portuguesa neste domínio. No entanto, 76% das pesquisas portuguesas foram direcionadas aos primeiros anos de escolaridade, enquanto somente 18% das pesquisas brasileiras foram direcionadas ao ensino fundamental. No que se refere aos dados sobre as abordagens e/ou perspectivas CTS presentes nas teses de doutorado defendidas nas instituições de ensino superior brasileiras e portuguesas, pode-se identificar que a principal abordagem/perspectiva de educação CTS é a Raciocínio Lógico (40%, 10 teses de um total de 24), seguida pela Sociocultural (39%, 9 teses de um total de 24), Histórica (3 teses), Socioecojustice (2 teses) e Aplicação/Design (1 tese). De modo geral, as análises revelaram que, mesmo existindo consenso entre a comunidade acadêmica envolvida com os estudos sobre a educação CTS, diferentes interpretações sobre o ensino de Ciências CTS ao longo das décadas estão a surgir, revelando assim um campo que se encontra em processo de construção dinâmica.

The didactic proposal was based on the Learning Theory of Ausubel, on orientations for the implementation of educational hypermedia systems and on approaches derived from the research in Science Teaching, among which are the Science- -Technology-Society focus, the reflections on the pedagogical importance of the History and Philosophy of Science, and the considerations about Modern Physics insertion in the High School. The program was evaluated by researchers of the area of Physics Teaching and undergraduate students in Physics Teaching and, after the incorporation of some of the suggestions done, it was tested by students of the third year of high school of a public school. Indications were obtained that the use of the computer was a factor of students’ motivation; the diversity of media elements helped them to set attention to the content and contributed to phenomena visualization and interpretation, also facilitating reasoning; the hypertext structured in accordance with the ausubelian principles contributed to the perception of the relationship among the concepts and helped with the development of subsumers to support subsequent learning. It was verified that the evaluated didactic proposal facilitated the evolution of the conceptions of most of the students regarding the concept of mass-energy equivalence and its implications; the relationships among Science, Technology and Society, including environmental and political aspects; the role of Ethics in the development and application of the scientific knowledge; the progress of the Science along the time. / Doutor

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / The origin of the movement known as Science-Technology-Society (STS), with repercussions in the Science Education, is associated to the questioning of the supposed neutrality of Science & Technology (CT). In Science Education, in the Brazilian context, STS can be considered a growing line of research, in a process of consolidation. However, how the nonneutrality of Science & Technology has been worked, in this line of research, considering the production of knowledge present in Brazilian journals from the area of Science Education? This constitutes the research problem. It is aimed to analyze how the non-neutrality of CT, in the CTS line of research, has been worked on the production of knowledge, present in Brazilian journals in the area of Science Education. As specific objectives: to identify and to characterize the approach given to the dimensions of the non-neutrality of Science- Technology in Brazilian journals, from the area of Science Education; to deep the understanding about the non-neutrality of Science-Technology and to signal referrals for the Science Education, which contribute to the understanding of non- neutrality of Science- Technology, particularly in the field CTS. In terms of theoretical and methodological referrals, consists of qualitative research, bibliographical, being the corpus of analysis constituted from articles presented in three journals published in Brazil, of the area of Science Education. This was submitted to the discursive textual analysis, which consisted of three steps: unitarization, categorization and communication. From the search results, was produced a metatext. The interaction between theoretical and empirical elements resulted in three categories, which summarize the research results: a) the agenda transfers intentions to the scientific-technological product; b) partial understanding of the non-neutrality of CT; and c) the knowledge produced (product) does not is the result only of the traditional epistemic factors: logic + experience. / A origem do denominado movimento Ciência-Tecnologia-Sociedade (CTS), com repercussões na Educação em Ciências, está associada ao questionamento da suposta neutralidade da Ciência-Tecnologia (CT). Na Educação em Ciências, no contexto brasileiro, CTS pode ser considerada uma linha de pesquisa em crescimento, num processo de consolidação. Contudo, como a não neutralidade da Ciência-Tecnologia tem sido trabalhada, nesta linha de pesquisa, considerando a produção de conhecimento presente, em periódicos brasileiros, da área de Educação em Ciências? Este constitui-se no problema de pesquisa. Tem-se como objetivo geral analisar como a não neutralidade da CT, na linha de pesquisa CTS, tem sido trabalhada, na produção do conhecimento, presente em periódicos brasileiros, na área de Educação em Ciências e objetivos específicos: identificar e caracterizar a abordagem dada, à dimensão da não neutralidade da Ciência-Tecnologia, em periódicos brasileiros, da área de Educação em Ciências; aprofundar a compreensão sobre a não neutralidade da Ciência-Tecnologia e sinalizar encaminhamentos, para a Educação em Ciências, que contribuam para a compreensão da não neutralidade da Ciência-Tecnologia, particularmente no campo CTS. Em termos de encaminhamento teórico-metodológico, constitui-se de pesquisa qualitativa de cunho bibliográfico, sendo o corpus de análise constituído a partir de artigos presentes em três periódicos, editados no Brasil, da área de Educação em Ciências. Este foi submetido à análise textual discursiva, constituída de três etapas: unitarização, categorização e a comunicação, sendo que, dos resultados da pesquisa, resultou a produção de um metatexto. Da interação entre elementos teóricos e empíricos resultaram três categorias, as quais sintetizam os resultados da pesquisa: a) a agenda transfere intencionalidades para o produto científico-tecnológico; b) compreensão parcial da não neutralidade da CT e c) o conhecimento produzido (produto) não é resultado apenas dos tradicionais fatores epistêmicos: lógica + experiência.

Fundação de Amparo a Pesquisa no Estado do Rio Grande do Sul / In search of a distinctive chemical education, with meaning for social and productive life of young high school students, the present study investigates how the theme "pollution" may facilitate the construction of the teaching and learning process of redox reactions content of high school students under a STSE (Science-Technology-Society-Environment) approach. For this, firstly, we sought theoretical references about the conceptual part of redox reactions and the theme "pollution". Then, we conducted an analysis of papers published in the journal Chemistry at the New School , with the intention of investigating how the redox reactions have been explored, their different approaches and their impact on the teaching of chemistry. From this, we developed a proposal to approach the redox reactions in the classroom, which was assessed through interventions with the second year high school students from a public school of Santa Maria, RS. Interventions in the classroom were carried out in two steps, both based on the methodology of the three pedagogical moments. The first developed inorganic redox content associated with the pollution of soil, whereas the second involved some organic redox reactions through the water pollution, specifically the treatment of effluents. This is a qualitative research. To collect data, we use questionnaires and textual productions, they were analyzed according to the Discursive Textual Analysis. The results allowed us to conclude that the development of redox reactions associated with the theme "pollution" by a STSE perspective favored teaching and learning of chemistry, as we observe an improvement in the construction of students knowledge. / Na busca de um ensino de química diferenciado, com significado para vida social e produtiva de jovens estudantes do nível médio, a presente pesquisa investiga como a temática Poluição pode favorecer a construção do processo de ensino aprendizagem do conteúdo de reações redox para estudantes de nível médio sob um enfoque CTSA (Ciência-Tecnologia-Sociedade-Ambiente). Para isso, primeiramente, buscamos referenciais teóricos a respeito da parte conceitual das reações redox e a temática Poluição . Em seguida, realizamos uma análise dos artigos publicados na revista Química Nova na Escola, com a intenção de investigar como as reações redox estão sendo exploradas, suas diferentes abordagens e sua repercussão no ensino de Química. A partir disso, desenvolvemos uma proposta para abordar as reações redox em sala de aula, que foi avaliada através de intervenções realizadas com estudantes da segunda série do nível médio de um colégio estadual de Santa Maria, RS. As intervenções em sala de aula foram realizadas em duas etapas, ambas baseadas na metodologia dos Três Momentos Pedagógicos. A primeira desenvolveu o conteúdo inorgânico de oxirredução associado à poluição do solo, enquanto que a segunda envolveu algumas reações orgânicas de oxirredução através da poluição da água, especificamente o tratamento de efluentes. A pesquisa é de caráter predominantemente qualitativo. Para a coleta de dados, utilizamos de questionários e produções textuais, analisados de acordo com a Análise Textual Discursiva. Os resultados encontrados nos permitiram concluir que o desenvolvimento das reações redox associadas a temática Poluição por um perspectiva CTSA favoreceram o ensino e a aprendizagem de Química, visto que observamos um avanço na construção do conhecimento dos estudantes.

From the principles of generalized symmetry and reflexivity, we expanded our understanding of the theoretical body to reflect on the Didactic Sequence constructed as a network of human and non-human actors in constant interest dispute. Thus, the overall objective of the work was to identify which nodes hold the networks built to each other. Among the actors identified in this construction, we highlight the authors of the Didactic Sequence (researcher, teacher of the university field and teacher of the school field), the high school students who became involved in the activities, the theoretical reference adopted and the studies of the relations between Science, Technology and Society. It should be noted that each of these actors associate with others in a heterogeneous network and in constant movement. In each chapter we map the actorsnetworks that translate this attempt to converge interests and values of the researcher, Actor-Network Theory, Research in Science Teaching and School. Finally, we indicate some of the clashes perceived in the process, as well as fight that, although they are bubbling, go unnoticed by some of the actors present. / Este trabalho se apropria da Teoria do Ator-Rede como referencial teórico e metodológico para elaborar uma Sequência Didática em que alunos do Ensino Médio possam explorar controvérsias em torno de artefatos tecnocientíficos. A partir dos princípios de simetria generalizada e reflexividade, expandimos nosso entendimento do corpo teórico para refletir sobre a Sequência Didática construída como uma rede de atores humanos e não humanos em constante disputa de interesses. Dessa forma, o objetivo geral do trabalho foi identificar quais os nós que prendem as redes construídas umas às outras. Entre os atores identificados nesta construção destacamos os autores da Sequência Didática (pós-graduando formador, professor formador do campo universitário e professor formador do campo escolar), os alunos formadores do Ensino Médio que se envolveram nas atividades, o referencial teórico adotado e os estudos das relações entre Ciência, Tecnologia e Sociedade. Cabe ressaltar que cada um destes atores se associam a outros tantos em uma rede heterogênea e em constante movimento. Em cada capítulo cartografamos os atores-redes que traduzem esta tentativa de convergir interesses e valores do pós-graduando formador, da Teoria do Ator-Rede, da Pesquisa em Ensino de Ciências e da Escola. Por fim, indicamos alguns embates percebidos no processo, assim como enfrentamentos que, apesar de estarem borbulhando, passam despercebidos por alguns dos atores presentes.
