M.Ed. / Renewal represents an improvement in accepted existing practice. This implies that the old practice is just not good enough any longer. Similarly, the knowledge and training base of lecturers at technical colleges fell short with the introduction of the new National Intermediate Certificate, as well as the National Senior Certificate in 1992. The subject-related problems which emerged, could have been solved by various techniques. The quality circle, self-directed work team and support groups, are three group-related problem-solving techniques to be assessed in this study. The three techniques share group participation as a common characteristic. Each of these techniques still maintains a unique approach and method in solving a problem. One would have a remarkable problem-solving technique if one could capitalise on all the positive aspects of the various techniques. The introduction of the new National Intermediate Certificate and the National Senior Certificate, is a direct result of adherence to community needs. The new courses demanded implementation of computer training in various fields of study at technical colleges. A curriculum analysis focusing on Parktown College, led to the identification of three fields of study affected by the introduction of the computer. Lecturers responsible for computer training experienced and still experience various problems. These problems were identified by means of a focus group interview.

Parte dessa questão refere-se à importância de formar formadores desses professores. Este trabalho teve por objetivo compreender como ocorreu o meu processo de formação para o ensino de ciências naturais no Projeto Ara Verá - curso de formação de professores indígenas kaiowá/guarani de Mato Grosso do Sul. Para tanto, optei por fazer uma narrativa da minha experiência nesse contexto. Essa opção se ancora no movimento que adota a abordagem biográfica como perspectiva epistemológica, pois admite que a formação do professor também se dá na experiência e que esse processo deve ser investigado. A narrativa foi concebida como uma viagem aberta a reflexões e a diferentes teorizações, cada uma recrutada a seu tempo, em função dos desafios apresentados. Para conduzir-me nas reflexões, utilizei como ponto de partida os registros que fiz da minha atuação no Projeto e, por meio deles, transitei por entre três movimentos confluentes e interpenetrantes: o re-conhecimento de mim mesma, dos Kaiowá/Guarani e dos nossos modos de conhecer e interpretar o mundo. Nesse percurso formativo, fui aprendendo a nos conhecer como sujeitos históricos, com visões de mundo distintas e com vontade de tornar as aulas de ciências naturais em contextos de encontro entre culturas, de troca de saberes e de influências recíprocas. / Abstract: One of the challenges faced by the indigenous school in the present time is the teacher's education for teaching in a specific, differentiated, intercultural and bilingual school. Part of this problem concerns the importance to build teachers for these teachers This research aimed to understand how occurred my process of education for teaching natural sciences in the Projeto Ara Verá - education program for indigenous students kaiowa/guarani of Mato Grosso do Sul - Brasil. For in such away I decided to make a narrative of my proper experience in this context. This choose has anchors in the movement that adopts the biographical boarding as epistemologic perspective, because accepts that the teacher's education also is given by experience and that this process must be investigated. This narrative was conceived as an open trip to the reflections and the different theorization each one enlisted opportunely, as the challenge were presented during the journey. To lead me in the reflections, I used as starting point the registers that I made from my performance in the Projeto Ara Vera and I transited among three confluent and interpenetrating movements: the re-cognition of myself, of Kaiowá/Guarani and our ways to know and to interpret the world. In this educative process, I was learning how to know us a historical citizens, with different world perspective, and with desire to become the natural science classes on intercultural context, within knowledge exchange and reciprocal influences. / Doutor

Intermediate elementary students (grades 4 and 5) frequently struggle to become scientifically literate in their general education classrooms. Scientific literacy includes knowing how to access and use information found in science texts. Unfortunately, many students struggle to read and understand science texts (Michalsky, Mevarech, & Haibi, 2009, p. 363). Fortunately, elementary students have shown improvement in reading comprehension when explicitly instructed in cognitive and metacognitive strategies to comprehend expository text in settings that support collaboration and flexible application of comprehension strategies, and have meaningful opportunities for reading and writing (Mastropieri & Scruggs, 2004; Palincsar & Klenk, 1992). A method that includes these components is reciprocal teaching (RT; National Reading Panel, 2000). RT has been used during content area instruction to increase reading comprehension skills of intermediate elementary students without disabilities in general education classrooms (King & Johnson, 1999; Lederer, 2000; Lubliner, 2004). These reading comprehension gains have been maintained by students on follow-up tests after the RT intervention has been withdrawn (Palincsar & Brown, 1984; Westera & Moore, 1995). This study examined the effects of RT on the science literacy of intermediate elementary students (grades 4-5) participating in inclusive science classes. Students with learning disabilities (SWLD), students at-risk (AR), and students in general education (GE) participated in this study. General education teachers used RT with science texts to improve science literacy. Pre/post science quizzes were used to assess the effects of the RT intervention, and post/follow-up tests assessed potential maintenance of the RT. s / Analyses of the data showed that the RT intervention resulted in improved science comprehension overall, and for each student group. In addition, the results showed that the gains were maintained for the individual student grouping after the RT intervention was removed, although these gains were not found overall.The study demonstrated that the use of RT during science instruction in inclusive, intermediate elementary classes assisted students who are AR, SWLD, and students in GE to attain science knowledge using standard science texts and materials. These results extend the experimental literature on science literacy and reciprocal teaching, particularly among intermediate elementary students. / by Kim E.

This qualitative case study examined how middle school science teachers conducted collaborative inquiry and reflection about students’ conceptual understanding, and how individual teachers in the middle school science group acted and made reflections in response to their collaborative inquiry. It also examined external influences that affected the teachers’ ability to engage in collaborative inquiry. Observational, written, and interview data were collected from observations of teachers’ face-to-face meetings and reflections, individual interviews, a focus group interview, and online reflections. The results of this study revealed that collaborative inquiry is a form of professional development that includes answering curricular questions through observation, communication, action, and reflection. This approach was developed and implemented by middle school science teachers. The premise of an inquiry is based on a need with students. Middle school science teachers came to consensus about actions to affect students’ conceptual understanding, took action as stated, and shared their reflections of the actions taken with consideration to current and upcoming school activities. Activities involved teachers brainstorming and sharing with one another, talking about how the variables were merged into their curriculum, and how they impacted students’ conceptual understanding. Teachers valued talking with one another about science content and pedagogy, but did find the inquiry portion of the approach to require more development. The greatest challenge to conducting collaborative inquiry and reflection was embedding teacher inquiry within a prescribed inquiry that was already being conducted by the Sundown School District. Collaborative inquiry should be structured so that it meets the needs of teachers in order to attend to the needs of students. A conducive atmosphere for collaborative inquiry and reflection is one in which administrators make the process mandatory and facilitate the process by removing an existing inquiry. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2013.

This mixed method study investigated K-6 teacher candidates' beliefs about informal science instruction prior to and after their experiences in a 15-week science methods course and in comparison to a non-intervention group. The study is predicated by the literature that supports the extent to which teachers' beliefs influence their instructional practices. The intervention integrated the six strands of learning science in informal science education (NRC, 2009) and exposed candidates to out-of-school-time environments (NRC, 2010). Participants included 17 candidates in the intervention and 75 in the comparison group. All were undergraduate K-6 teacher candidates at one university enrolled in different sections of a required science methods course. All the participants completed the Beliefs about Science Teaching (BAT) survey. Reflective journals, drawings, interviews, and microteaching protocols were collected from participants in the intervention. There was no statistically significant difference in pre or post BAT scores of the two groups; However, there was a statistically significant interaction effect for the intervention group over time. Analysis of the qualitative data revealed that the intervention candidates displayed awareness of each of the six strands of learning science in informal environments and commitment to out-of-school-time learning of science. This study supports current reform efforts favoring integration of informal science instructional strategies in science methods courses of elementary teacher education programs.

xi, 73 p. : ill. / Recent studies have demonstrated a clear gap between the skills that high school graduates obtain by the completion of high school and those that are necessary for success in college as well as the workforce. Demands for more rigorous preparation at the high school level have prompted some states to make changes to state standards and high school graduation requirements. This dissertation used a prediction study to examine the coursetaking patterns of high school students in science and their subsequent success in chemistry 1A at the college level. Analysis of obtained data using a two-way ANOVA was used to estimate the main effects of (a) number of semesters of science courses and (b) the type of science courses and (c) the interaction effect on college performance as indicated by the final course grade. The results of this study indicate that the main effect of type and the main effect of number of semesters are both significant statistically. Taking more semesters of science in high school is positively associated with the final grade in first-year college chemistry. Taking higher level science coursework in high school is also positively associated with final grade. The interaction of type by number of semesters is not significant, however. Taking more semesters of higher level science coursework does not increase the likelihood of doing well in college chemistry, as there is no observable significant influence on final grade in chemistry, beyond the main effects described previously. / Committee in charge: Paul Yovanoff, Chairperson; David Conley, Member; Kathleen Scalise, Member; Kenneth Doxsee, Outside Member

We also intend to highlight the use of images for the purpose of registration and circulation of knowledge. However, to develop this study in the field of History of Science, we chose as a case study the work A New Herball, published in 1568 by the british scholar William Turner (c.1510-1568). From this work, we present some discussions about the use of images and their relevance for the knowledge about nature at that time. We complement this work with a didactic sequence acting in the interface between the History of Science and Teaching, emphasizing science as human construction and the relevance of images in the process of communication of knowledge / Neste estudo, analisamos a relevância das imagens em herbários do século XVI, salientando principalmente alguns aspectos da relação imagem e texto presentes nos livros desse período.

The objective of the analysis is to verify the selections that have been made and the methodology predicted and well as made effective for teaching. The work is part of the History of School Disciplines area led by Andre Chervel and Bruno Belhoste, which considers school textbooks a privileged resource of contents that affects pedagogical practice and constitute the school culture. I develop the material analysis of the books by taking Roger Chartier as a theoretical reference, to identify editorial devices that reveal strategies and intentions of the reader's use of the work. The research highlighted devices by which textbooks have come to guide readings and uses, as well as the ways in which they have appropriated notions known as "object lessons / Este trabalho analisa exemplares de livros escolares que veicularam conteúdos de ciências destinados à instrução pública elementar entre os séculos XIX e XX. O objetivo da análise é verificar os conteúdos selecionados e a metodologia prevista e efetivada para o ensino. O trabalho se insere na área da História das Disciplinas Escolares, tributária de André Chervel e Bruno Belhoste, que considera os livros escolares fontes privilegiadas de conteúdos que se inserem na prática pedagógica, constituindo a cultura escolar. Com base em Roger Chartier, fazem-se análises materiais dos livros para identificar dispositivos editoriais reveladores de estratégias e intencionalidades de usos da obra pelos leitores. A pesquisa evidenciou dispositivos pelos quais os livros escolares passaram a orientar leituras e usos, bem como as maneiras pelas quais eles se apropriaram de noções disseminadas como “lições de coisas”

To improve students’ scientific literacy and their general perceptions of chemistry, I enacted critical chemistry education (CCE) in two “regular level” chemistry classes with a group of 25 students in a suburban, private high school as part of this study. CCE combined the efforts of critical science educators (Fusco & Calabrese Barton, 2001; Gilbert 2013) with the performance expectations of the Next Generation Science Standards (NGSS) (NGSS Lead States, 2013a) to critically transform the traditional chemistry curriculum at this setting. Essentially, CCE engages students in the critical exploration of socially situated chemistry content knowledge and requires them to demonstrate this knowledge through the practices of science. The purpose of this study was to gauge these students development of chemistry content knowledge, chemistry interest, and critical scientific literacy (CSL) as they engaged in CCE. CSL was a construct developed for this study that necessarily combined the National Research Center’s (2012) definition of scientific literacy with a critical component. As such, CSL entailed demonstrating content knowledge through the practices of science as well as the ability to critically analyze the intersections between science content and socially relevant issues. A mixed methods, critical ethnographic approach framed the collection of data from open-ended questionnaires, focus group interviews, Likert surveys, pre- and post unit tests, and student artifacts. These data revealed three main findings: (1) students began to develop CSL in specific, significant ways working through the activities of CCE, (2) student participants of CCE developed a comparable level of chemistry content understanding to students who participated in a traditional chemistry curriculum, and (3) CCE developed a group of students’ perceptions of interest in chemistry. In addition to being able to teach students discipline specific content knowledge, the implications of this study are that CCE has the ability to affect students’ critical science thinking in positive ways. However, to develop longer lasting, deeper critical insights that students use to participate in science-related issues outside of class, critical science education must be enacted longitudinally and across disciplines. Furthermore, it must be enacted in ways that either prompt or help students to transfer classroom learning outside of the classroom as they engage in critical issues in the classroom.
