A model for incrementally transforming the science classroom from traditional instruction to inquiry

Jerome, Tana Michelle 01 January 2006 (has links)
Explores the implementation of inquiry into the science classroom and presents a model for incrementally changing the traditional (behavioralist) instruction found in the science class to inquiry-based (constructivist) instructional strategies.

Using concept maps to explore preservice teachers' perceptions of science content knowledge, teaching practices, and reflective processes

Unknown Date (has links)
This qualitative study examined seven preservice teachers' perceptions of their science content knowledge, teaching practices, and reflective processes through the use of the metacognitive strategy of concept maps. Included in the paper is a review of literature in the areas of preservice teachers' perceptions of teaching, concept development, concept mapping, science content understanding, and reflective process as a part of metacognition. The key questions addressed include the use of concept maps to indicate organization and understanding of science content, mapping strategies to indicate perceptions of teaching practices, and the influence of concept maps on reflective process. There is also a comparison of preservice teachers' perceptions of concept map usage with the purposes and practices of maps as described by experienced teachers. Data were collected primarily through interviews, observations, a pre- and post-concept mapping activity, and an analysis of those concept maps using a rubric developed for this study. Findings showed that concept map usage clarified students' understanding of the organization and relationships within content area and that the process of creating the concept maps increased participants' understanding of the selected content. / The participants felt that the visual element of concept mapping was an important factor in improving content understanding. These participants saw benefit in using concept maps as planning tools and as instructional tools. They did not recognize the use of concept maps as assessment tools. When the participants were able to find personal relevance in and through their concept maps they were better able to be reflective about the process. The experienced teachers discussed student understanding and skill development as the primary purpose of concept map usage, while they were able to use concept maps to accomplish multiple purposes in practice. / by Judy L.

Do uso à mediação de tecnologias no ensino-aprendizagem de ciências: uma abordagem investigativa de prática educacional no ensino fundamental

Darronqui, Silvia Regina 28 June 2013 (has links)
Esta dissertação apresenta uma abordagem teórico-prática sobre a mediação de tecnologias no ensino-aprendizagem de ciências. Este estudo de caso foi desenvolvido com alunos de quatro turmas de nono ano do Ensino Fundamental do Colégio Estadual Professor Victor do Amaral, situado em Curitiba - PR. O principal objetivo desta pesquisa foi investigar se a problematização das tecnologias pode proporcionar a construção de um conhecimento diferenciado para o ensino-aprendizagem de Ciências no Ensino Fundamental. Entende-se aqui conhecimento diferenciado aquele que é crítico, reflexivo e contextualizado, que vai além dos conceitos e definições previstos no currículo. Esta pesquisa-ação qualitativa seguiu as seguintes fases: aplicação de questionário inicial, onde comprovamos a necessidade da existência desta pesquisa; realização de aulas de Física (Ciências) com a aplicação da metodologia problematizadora de Freire através de sequências didáticas fundamentadas teoricamente e aplicação de questionário final. As tecnologias estiveram presentes nas aulas como recurso pedagógico e conteúdo de ensino objetivando colaborarem para tornar os estudantes ativos, críticos e reflexivos em relação aos conteúdos trabalhados e às tecnologias. A metodologia utilizada nas sequências didáticas e, portanto, nas aulas, foi problematizadora, contendo os três momentos pedagógicos: problematização, organização e aplicação do conhecimento. Esta pesquisa fundamentou-se em autores como Freire, Vicente, Pacey, Postman e Bazzo, entre outros. Tendo por base “a importância do ato de ler” de Freire (1989) fez-se uma transposição para a necessária leitura das tecnologias, onde foram criados eixos norteadores do trabalho realizado. Essa reflexão teórica foi necessária para apoiar a reflexão que as sequências didáticas visavam a proporcionar nos estudantes. A coleta de dados se deu por meio de questionário inicial e final, por diário de campo e por transcrições das aulas gravadas em áudio. Os resultados mostraram que problematizar as tecnologias no ensino proporciona a apropriação de um conhecimento diferenciado. Concluímos que o ensino mediado sobre/com tecnologias contribui com a aprendizagem, favorecendo uma participação mais efetiva proporcionando discussão e reflexão nos estudantes, dinamizando assim o ensino de ciências. / This thesis presents a theoretical and practical approach about the mediation of technology in teaching and learning of Natural Sciences. This case study was developed with students from four classes ninth year of the Public Elementary School Teacher's Victor Amaral, located in Curitiba – PR. The main objective of this research was to investigate whether the questioning of technologies may provide for the construction of a knowledge for differentiated teaching and learning of Natural Sciences in Elementary Education. It is understood that differentiated knowledge that goes beyond that provided in the curriculum, which is critical, reflexive and contextualized. This qualitative action research followed the stages: application of the initial questionnaire, which proved the necessity of the existence of this research, conducting classes in Physics (Science) with the application of the questionable methodology of Freire through didactic sequences theoretically grounded and a questionnaire end. The technologies were present in the classroom as a teaching resource and learning content aimed collaborate to make students active, critical and reflective in relation to content and technology worked. The methodology used in the teaching sequences and therefore in the classroom, was problematical, containing the three pedagogical moments: problematization, organization and application of knowledge. This research was based on authors such as Freire, Vicente, Pacey, Postman and Bazzo, among others. Based on "the importance of the act of reading" Freire (1989) became a transposition to the necessary reading technologies, which were created guiding principles of the work. This theoretical reflection was needed to support the thinking that the didactic sequences aimed at providing the students. Data collection occurred through initial and final questionnaire for field diary and transcripts of audio-recorded lessons. The results showed that problematize technology in education provides a differentiated knowledge acquisition. We conclude that education mediated over/with technology contributes to learning, favoring a more effective participation by providing discussion and reflection among students, thus boosting science education.
