Ensino e aprendizagem dos processos de divisão celular no Ensino Fundamental / Strategies of learning and teaching on the cellular division processes at the basic levelPaula, Sabrina Ribeiro de 07 November 2007 (has links)
A recente explosão do conhecimento da genética molecular e o avanço da indústria da biotecnologia requerem que o público compreenda muitos conceitos da genética para a tomada de decisões sobre a pertinência do uso dessas novas ferramentas. Durante os últimos 30 anos a literatura educacional produziu conceitos e teorias para lidar com estas dificuldades, mas a maioria dos professores desconhece estas produções, principalmente porque os periódicos de referência são publicados em línguas estrangeiras (principalmente em inglês). Esta pesquisa-ação pretende preencher esta lacuna e foi baseada em testes que envolveram 283 estudantes de 12 a 15 anos de idade. Nela descrevemos as concepções dos estudantes sobre a localização e transmissão da informação genética antes e após a aplicação de uma seqüência didática elaborada especificamente para desenvolver estratégias metacognitivas de aprendizagem. As idéias dos estudantes foram colhidas por meio dos questionários e redações, nas quais os estudantes descrevem como imaginam ser o interior das células e dos gametas. Verificamos que as crianças do ensino fundamental possuem concepções semelhantes àquelas descritas para estudantes do ensino médio. A comparação das redações produzidas pelos estudantes antes e após a aplicação da seqüência didática permitiu verificar que o padrão mais comum de aprendizagem é sincrético, ou seja, as crianças tendem a distorcer as informações oferecidas pelo professor em virtude da existência de conhecimentos prévios. Por fim, a descrição e a documentação de seqüências didáticas planejadas a partir de conhecimentos produzidos na literatura educacional permitem o entendimento dos processos de transposição didática e a relação deste com a aprendizagem dos estudantes. / The recent knowledge explosion on the areas of genetics, molecular biology and biotechnology introduced many new concepts hard for common people to grasp in their decision-making processes. During the last 30 years or so the educational literature produced concepts and theories to cope with these difficulties but the vast majority of our elementary and highschool teachers remain unaware of them possibly because the available literature is written in foreign languages (mainly in English). The action-research here presented intends to fill this gap and was based on tests performed with 283 students aged 12 to 15. We describe their conceptions on the location and transmission of genetic information before and after the application of a didactic sequence specifically elaborated to develop metacognitive learning strategies. The students\' ideas were gathered by means of questionnaires and through essays describing how they imagine the interior of cells and germ-cells. We verified that children on basic educational level have conceptions very similar to those of students of middle-level education. The paired comparison of before and after essays suggests the existence of a common, syncretic learning standard. In plain language, the results indicate that previous informal knowledge of children tends to distort the formal information transmitted by their teachers. It is clear that the description and documentation of planned didactic sequences, available from the specialized literature, provide the understanding of the didactic transposition process and its relation with the students´ learning process.

University Faculty and Diverse Students' Self-Reported Attitudes toward Inclusive Teaching StrategiesAlamri, Abdulrahman Saleh 05 1900 (has links)
This dissertation examines a university faculty (n = 41) and diverse students (n = 93) including students with disability (n = 44), students without disability (n = 21), and international students (n = 28) regarding their attitudes toward and actions associated with inclusive instruction based on the universal design for learning (UDL) principles and practices. Two online surveys, the Inclusive Teaching Strategies Inventory (ITSI) and the Inclusive Teaching Strategies Inventory-Student (ITSI-S), were administered at a large, public Southwest university (N = 134). The ITSI and ITSI-S contain seven subscales representing the following constructs: (a) accommodations, (b) accessible course materials, (c) course modifications, (d) inclusive lecture strategies, (e) inclusive classroom, (f) inclusive assessment, and (g) disability laws and concepts. A series of multivariate analyses of variances (MANOVAs) measured the overall of attitude subscales and overall action subscales, and an independent-samples test (t-test) compared mean scores on the seven Attitude subscales and seven Action subscales to identify predictors of these attitudes and actions among faculty and students. The main findings were (a) significant differences among diverse students, where students with disability responded negatively on the Action subscales and (b) significant differences between faculty and diverse students where international students had a positive attitude on the Attitude subscales, whereas students with disability had a negative attitude on the Action subscales toward the actual practices of their faculty. Results of the current study respond to the gap in the literature by examining the inclusive instruction environment based on UDL in a university environment. The implications of these findings and recommendations for future research are discussed.

From policy to practice: an evaluation of the Unisa National Professional Diploma in Education from the perspective of social critical theoryMays, Tony John 30 June 2004 (has links)
The National Professional Diploma in Education is an in-service programme for classroom-based educators who have less than three years of professional training. The programme seeks to create a pathway to qualified teacher status in ways that will impact positively on classroom practice, prepare teacher-learners for the implementation of the new curriculum and provide a sufficiently rigorous foundation for further study. This evaluation adopted a fourth generation evaluation approach characterised by extensive engagement with programme stakeholders. Chapter 2 outlines an epistemological and philosophical framework of reference whilst Chapters 3 and 4 explore learning and teaching strategies and management and costing issues. The findings of these investigations lead to the recommendations made in Chapter 5. It is felt that the Unisa NPDE meets many of the goals of the programme, but further research is needed into the impact on classroom practice and into the management of the decentralised learner support. / Educational Studies / M.Ed.
