Tem como objetivo principal compreender como está se constituindo a Educação a Distância – EaD no Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Sul – IFRS, analisando o processo de institucionalização desta modalidade, buscando entender sua dinâmica, seus limites e possibilidades. Procura também conhecer as políticas públicas relacionadas a EaD e verificar em que medida as diretrizes políticas se concretizam nas ações de EaD no âmbito do IFRS; compreender a concepção de EaD dos diferentes atores que atuam nessa modalidade no contexto do IFRS; conhecer quais os saberes que esses diferentes atores acreditam ser necessários para atuar em EaD; entender como esses diferentes atores percebem o processo de institucionalização; além de compreender como está ocorrendo a capacitação para atuação com a modalidade EaD. Os principais teóricos que fundamentam o estudo e alguns autores que ajudam a compreender a pesquisa são Aebli (1958), Santaella (1997), Lévy (1999), Axt (2000), Peters (2001), Belloni (2003, 2009), Santos (2005), Schlemmer (2005, 2006), Silva (2006, 2012), Tardif (2007) e Preti (2009). A pesquisa é de natureza exploratória envolvendo análise qualitativa e quantitativa de dados por meio da realização de estudo de caso, utilizando os documentos oficiais da instituição e os questionários aplicados aos gestores, da reitoria e dos campi, e aos docentes do instituto. O resultado mais significativo indica que a EaD, no IFRS, ainda não é uma prática institucionalizada. Neste sentido, identificou-se que o IFRS tem reproduzido algumas falhas que já foram percebidas em outras instituições, onde os documentos institucionais trazem a ideia do formalismo, mas continuam a investir em práticas individuais de construção de projetos pedagógicos, de gestão de cursos, de uso de metodologias, etc. Entendemos que a contribuição efetiva da tese se dá no sentido da identificação da necessidade de mudar significadamente as ações individuais, para ações coletivas e compartilhadas, propondo-se a criação de momentos de diálogo e reflexão por parte dos gestores e comunidade em geral no que tange a EaD, a fim de que seja possível dar conta do processo de constituição e institucionalização da EaD no IFRS. / This research is in the context of the research line, Education, Development and Technologies of the Post-Graduation Program in Education of the University of Vale dos Sinos – UNISINOS. Its main objective is to understand how Distance Education is being formed - DE at the Federal Institution of Education, Science and Technology of Rio Grande do Sul – FIRS, analyzing the process of institutionalization of this kind, trying to understand its dynamics, its limits and possibilities. It also attempts to know the public policies related to the use of DE and verify in what measure the policy guidelines are made real in the DE actions under the FIRS; understand the concept DE of the different actors who act on this modality in the context of FIRS; know what knowledge that these different actors believe to be necessary to act on in DE; understand how these different actors perceive the institutionalization process; in addition to understanding how the training is taking place with the DE mode. The main theoretical that substantiate the study and some authors who help to undertand the research are Aebli (1958), Santaella (1997), Lévy (1999), Axt (2000), Peters (2001), Belloni (2003, 2009), Santos (2005), Schlemmer (2005, 2006), Silva (2006, 2012), Tardif (2007) and Preti (2009). The research is of explanatory nature involving qualitative and quantitative analysis of data by conducting a case study, using the official documents of the institution and the questionnaires applied to the managers, of the rectory and campuses and to the professors of the institute. The most significant result indicates that the DE, in the FIRS, is not yet an institutionalized practice. In this way, we see that, the FIRS has reproduced some flaws that have already been perceived in other institutions, where the institutional documents bring the idea of formalism, but keep on investing in individual construction projects of pedagogical practices, management courses, using methodologies, etc. We understand that the effective contribution of the thesis is given towards identifying the need for significantly change the individual actions to collective and shared actions, proposing the creation of moments of dialogue and reflection by managers and the general community regarding DE in order to make it possible to account for the constitution process and institutionalization of DE in FIRS.

As trajetórias compreendem o processo em que a Instituição se desenvolveu, entre as décadas de 1970 a 2010. As memórias individuais, tomadas como documentos, foram analisadas coletivamente. A pesquisa tem como objetivo discutir acerca da educação profissional e dos caminhos trilhados por cinco docentes que participaram dos processos de implementação e das transformações ocorridas no Ensino Técnico Profissionalizante. Nesse contexto, a ênfase recai sobre as práticas do exercício da docência no ensino profissionalizante e na construção de um espaço escolar. O estudo aborda conceitos ligados à historicidade, ao discurso e às experiências relatadas. A metodologia desenvolvida relaciona-se aos pressupostos da História Oral que, valendo-se das narrativas memorialísticas e sob o aporte teórico da História Cultural, produz um corpus empírico passível de estudo. As memórias analisadas permitiram entrever diferentes aspectos relacionados à educação profissional, ao espaço escolar e as práticas docentes. As recordações e os esquecimentos possibilitaram entrever, de forma geral, o caminho percorrido pela educação profissional no Brasil e, em particular, alguns fragmentos deste caminho no estado do Piauí. / This study historically reconstructs the trajectories of retired teachers of the Federal Institute of Education, Science and Technology of Piauí, in a route comprising its inception as ETFPI to become IFPI. The trajectories comprehend the process in which the institution developed between the 1970s and 2010. The individual memories, taken as documents, were analyzed collectively. The research aims to discuss professional education and the pathways of five teachers who participated in the implementation of processes and changes occurring in the Technical Education. In this context, the emphasis is on teaching practices in vocational education and on the construction of a school environment. The study discusses concepts related to historicity, speech and the experiences reported. The developed methodology is related to the assumptions of Oral History that, taking advantage of memory narratives and under the theoretical framework of Cultural History, produces an empirical corpus to be studied. The analyzed memories allowed us to find out different aspects related to professional education, school environment and teaching practices. The remembrances and forgetfulness allowed us to find out, in general, the path taken by professional education in Brazil and, in particular, some fragments of this path in the state of Piauí.

The purpose of this study was to examine the effects of constructivist instruction on the achievement, attitude towards science teaching, science process skills and retention of fourth grade preservice science teachers in Science Teaching Methods II course. Two groups (one experimental and one control) were assigned from Hacettepe University Faculty of Education Department of Science Education. Experimental group consisted of 53 preservice science teachers and the control group consisted of 50 preservice science teachers / totally 103 preservice science teachers participated in this study. Quasi experimental research design was used in this study. Constructivist instruction was used in experimental group and traditional instruction was used in control group during the teaching and learning process. This research study was conducted in fall semester of the 2007-2008 academic year and lasted 15 weeks including the final examination term. Science Process Skills Test, Attitude towards Science Teaching Scale and Achievement Test in Science Teaching Methods II course were administered to participants three times / at the beginning of the study, immediately after the implementation process and 10 weeks later. A mixed between within ANOVA with repeated measures was used as a statistical technique for analyzing quantitative data and both descriptive and content analysis was used for analyzing questionnaire, formative and summative focus group interviews. Statistical mean difference was obtained for all tests in favor of experimental group and the findings of quantitative data analysis results were supported by the qualitative data analysis results. After interpreting the results, it can be claimed that constructivist instruction is effective in preservice science education.

Marine aquariums are excellent venues for accomplishing the purposes of marine education, and school field trips conducted at non-formal settings continue to be an important part of K-12 education. The purpose of this study was to provide not only quantitative data regarding the extent and quality of marine aquarium field trips conducted by elementary schoolteachers in Seoul, South Korea, but also to provide a qualitative description of marine aquarium education conducted in the USA and Canada. A Web survey designed to examine Korean teachers' experiences and perspectives on aquarium field trips identified several concerns regarding Korean marine aquarium education, and a case study conducted at three aquariums in the USA and Canada described the characteristics and qualities of marine aquarium education at those aquaria. Recommendations for both Korean aquaria's educational roles and Korean elementary schools' successful field trips to aquaria are presented with the goal of improving the quality of Korean marine aquarium education.

This study examines science teachers' beliefs and ideas about science prior to and following a one and a half day workshop on Indigenous Knowledge and Traditional Witsuwit'en knowledge of science. It is part of a wider study initiated by the Aboriginal Enhancements Branch of the BC Ministry of Education to determine why Aboriginal students are not enrolling in the sciences. A broad range of qualitative methodologies were applied, including pre and post instructional questionnaires, an experiential field trip to traditional Witsuwit'en territories as well as an instructional workshop and a dialogue process. Aspects of Indigenous methodology were included that were central to the lived experience of the Witsuwit'en people whose territories we were on and with whom the research was being conducted. Post-workshop questionnaire responses indicated that teachers' developed a broader understanding of Witsuwit'en Traditional Knowledge systems and a deeper respect for the contributions of the local First Nations to the sciences.

This thesis presents the development, implementation and evaluation of a cross-cultural, experiential marine program that occurred in 2007 at a Senior High School in Sooke, British Columbia. The program consisted of a field-intensive, marine curriculum that acknowledged the contributions of Aboriginal science (Traditional Ecological Knowledge and Wisdom) as complementary to Western science, when understanding and monitoring the coastal environment. Students of both Aboriginal (N= 8) and non-Aboriginal (N= 11) heritage were surveyed before and after instruction of theirknowledge and beliefs about marine science and Aboriginal culture. Prior to instruction,students tended to have positive opinions about Aboriginal culture and marine science, although their knowledge in marine ecology and oceanography was not strong. However, students showed a good understanding of human impacts on the environment. An important finding was that after instruction all students, regardless of cultural heritage, gender or previous coursework, gained positively in all measures from the experience.

Two groups of students in introductory physics courses of an Access Program for engineering technologies were the subjects of this study. Students with a wide range of academic histories and abilities were enrolled in the program; many of the students were re-entry and academically unprepared for post-secondary education. Five years of historical data were evaluated to use as a benchmark for revised instruction. Data were gathered to describe the pre-course academic state of the students and their academic progress during two physics courses. Additional information was used to search for factors that might constrain academic success and as feedback for the instructional methods. The data were interpreted to regulate constructivist design features for the physics courses. The Engineering Technology Access Program was introduced to meet the demand from non-traditional students for admission to two-year engineering technology programs, but who did not meet normal academic requirements. The duration of the Access Program was two terms for electronic and computer engineering students and three terms for civil and mechanical engineering students. The sequence of mathematics and physics courses was different for the two groups. The Civil/Mechanical students enrolled in their first mathematics course before undertaking their first physics course. The first mathematics and physics courses for the Electronics students were concurrent. Academic success in the two groups was affected by this difference. Over a five-year period the success rate of students graduating with a technology diploma was approximately twenty-five percent. Results from this study indicate that it was possible to reduce the very high attrition in the combined Access/Technology Programs. While the success rate for the Electronics students increased to 38% the rate for the Civil/Mechanical students increased dramatically to 77%. It is likely that several factors, related to the extra term in the Access Program for the Civil/Mechanical students, contributed to this high retention rate. Additional time, with less academic pressure in the first term of the Access Program, provided the Civil/Mechanical students with the opportunity to develop academic skills and maturity resulting in improved self-concept and academic identity. These students may have been better equipped to take advantage of the alternate instructional setting of the revised physics courses. Results from a wide range of studies in Physics Education Research provide ideas and opportunities to improve instruction and students conceptual understanding in introductory physics courses. Most studies focus on traditional students and curriculum. The development and implementation of alternate curriculum and instruction may improve outcomes for different groups of students, particularly for students in disciplines indirectly related to the sciences.

The purpose of this research study was to explore why some Aboriginal students participate in senior secondary Biology, Chemistry, or Physics and achieve a high level of academic success (67% or higher) in these courses. The following key questions were addressed: 1. What are the experiences and perceptions of Aboriginal students with regard to senior secondary science? 2.What role, if any, does culture play for Aboriginal students who are successful in the senior secondary sciences? 3. What are the factors that either contribute to or hinder success by Aboriginal students in science-related courses? Ten Aboriginal participants were interviewed from the Greater Victoria School District. Metaphor Interviews, Literal Interviews and a Focus Group were used to collect data. The results indicated that Aboriginal ancestry was important to the identity of many of the participants, but it was not a significant contributing factor in their academic success in senior secondary science.

This study intented to investigate the effects of activities based on role-play on ninth grade students&rsquo / achievement and attitudes at simple electric circuits. In this study, Physics Achievement Test was developed to evaluate students&rsquo / achievement on simple electric circuits and role-play activities about simple electric circuits were prepared. In addition, Physics Attitude Scale was administered to explore students&rsquo / attitude towards physics. The present study was conducted at one of the high schools in Acipayam during 2003-2004 Spring Semester with a total number of 104 (51 female and 53 male) 9th students from four classes of two physics teachers. One class of each physics teacher was assigned as experimental and instructed by role-play activities on the other hand the other classes of each physics teacher was as control group and instructed by traditional method. The teachers were trained for how to implement role-play activities in the class before the study began. Physics Attitude Scale and Physics Achievement Tests were applied twice as a pre-test and after a three-week treatment period as a post-test to both groups to assess and compare the effectiveness of two different types of teaching / role-play versus traditional teaching method. Data were collected utilizing Physics Achievement Test and Physics Attitude Scale. Data of this study were analyzed utilizing descriptive and inferential statistics. The scores of the post-tests were analyzed by statistical techniques of Multivariate Analyses of Covariance (MANCOVA). Experimental group compared to control group tended to favor a significant difference in the achievement. However the statistical analysis failed to show any significant differences between the experimental and control groups&rsquo / attitude towards physics at simple electric circuits.

The main purpose of this study was to develop a three-tier test for assessing ninth-grade students&rsquo / misconceptions about simple electric circuits. The first tier of an item on the test presents an ordinary multiple choice question, the second tier presents a set of reasons for the response given to the first tier, and the third tier questions if examinees are confident for their responses to the first two tiers. The study was carried in Polatli, the biggest outlying district of capital Ankara. In the light of the related literature, interviews were conducted by the researcher so as to collect information about students&rsquo / understanding of simple electric circuits. Thereby, a list of misconceptions was acquired and it was used for developing an open-ended questionnaire. Next, the questionnaire was examined by two physics teachers and an instructor from METU for establishing content validity. The questionnaire was administered to 99 ninth-grade students and their responses were categorized in the purpose of determining the distracters of the three-tier test / the Simple Electric Circuit Diagnostic Test (SECDT). At last, the SECDT was developed and administered to 124 ninth-grade students. The validity of the SECDT was established by means of quantitative methods in addition to the qualitative methods. A positive correlation coefficient was estimated between student scores and confidence levels, that is, successful students on the SECDT were more confident for their responses than unsuccessful students. This result means that the SECDT works properly, for example, students generally understood the items and found their reasoning among the distracters. Also, what items measure was investigated by means of factor analysis, and three reasonable factors were obtained. Furthermore, proportions of false positives and negatives were estimated and found as 17.47 % and 10.82 %, respectively. As well as, Cronbach alpha reliability coefficient of student scores was estimated as 0.69, but the reliability coefficient of student misconception scores was estimated as 0.33. Consequently, the SECDT scores are valid and reliable measure of students&rsquo / qualitative understanding of simple electric circuits / however, misconception scores may not be reliable.
