Charles University in Prague - Faculty of Science Department of Teaching and Didactics of Chemistry Albertov 3, 128 40 Praha 2, Czech Republic Educational project Saccharides Topic Work in Chemistry for high School Bc. Renata Šedivá sedivarenata@gmail.com This diploma thesis is a suggestion of educational project Saccharides classifiable into education of Chemistry in 3rd year of four-year grammar school. In the first part there is a research of literature sources concerning the issue project education. The Following part is a suggestion of educational project Saccharides, its product are lessons about the topic saccharides, which are designed, prepared and taught by the students. The suggestion of the project contains a timetable of the project, instructions and methodology for individual parts of the project (motivation, preparation of lessons, laboratory works, presentation of lessons, final practice, test and reflection), methodological notes and documentation to the implementation of the project at Grammar school in Dvůr Králové nad Labem.

Thesis is fixed on inter-subjects relations between chemistry and geology in context of science education. Thesis concern subject matter defined in curricula for grammar schools, which is devoted inorganic chemistry, mineralogy and petrology. Next there is lucid compile inclusion these themes to school curricula in other grammar schools. Thesis emphasizes mainly to practical works in teaching mentioned subjects i.e. experiments. There are compile topics for chemical and physical experiments, which are useful for demonstration inter- subject relations between these subjects and geology. Worksheets with creative solutions were made for these experiments; there are component of enclosure of this thesis.

Este trabalho relata uma proposta metodológica fundamentada na perspectiva construtivista, que teve como objetivo investigar a contribuição da utilização de atividades experimentais realizadas com materiais alternativos e de baixo custo no aprendizado de conteúdos de química. A pesquisa foi realizada com alunos da 2ª série do Ensino Médio da Escola Agrotécnica Federal de Sombrio/SC. As atividades experimentais foram desenvolvidas com o intuito de promover a interação dos alunos com seus colegas e professor. Durante a realização destas atividades procurou-se levantar as concepções espontâneas dos alunos, que têm por base o conhecimento prévio a respeito dos fenômenos em estudo. A investigação se delineou como um estudo qualitativo, de caráter descritivo das análises das respostas coletadas nos dados de pré e pós-testes realizados com os alunos, embora também se tenha quantificado com números algumas respostas dos mesmos. Os resultados dessa intervenção didática indicaram que a contextualização de atividades experimentais, valorizando os conhecimentos prévios, as interações entre aluno-aluno e aluno-professor pode ser uma boa forma de contribuir para a melhoria do ensino de química, assim como, para ampliar o nível de aprendizagem dos alunos, dos conteúdos fundamentais de química. / This work explains a methodological proposition based on the construtivist perspective, that had as objective to investigate the contribution of the use of experimental activities carried through with low cost alternative materials in the learning of chemistry contents. The research was carried through with pupils of 2nd levels of High School of Sombrio Federal Agrotechnical School/SC. The experimental activities had been developed with intention to promote the interaction of the pupils with their colleagues and teacher. During the accomplishment of these activities it was looked to raise the spontaneous conceptions of the pupils, who have as base the previous knowledge regarding the phenomena in study. The inquiry delineated itself as a qualitative study with descriptive character of the analyses of the collected answers in the data of the previous and after-tests carried through with the pupils, even so it has quantified with numbers some answers of those students. The results of this didactic intervention had indicated that the contextualization of experimental activities, valorizing the previous knowledge, the interactions between pupil-pupil and pupil-teacher can be a good way to contribute for the improvement of the chemistry education, as well as, to extend the level of learning of the pupils in the basic contents of chemistry.

This thesis reports a series of studies into textbook authors', teachers' and students' use of analogies to improve students' understanding of abstract chemistry concepts. The five research problems considered: (a) the nature and extent of analogy use in textbooks; (b) the views of textbook authors and editors concerning analogies; (c) how, when, and why analogies were used by experienced chemistry teachers; (d) the development of an instrument to determine chemistry students' understanding of analogies; and (e) how chemistry students use the analogies presented as part of their chemistry instruction.Study One reports the findings of an investigation of ten chemistry textbooks used by Australian students for the nature and extent of analogy inclusion. The study found that, while used sparingly, analogies were employed more frequently in the beginning of textbooks and that the analogies used concrete analog domains to describe abstract target concepts. There was considerable use of pictorial-verbal analogies although simple analogies comprised a substantial proportion and stated limitations or warnings were infrequently employed.Study Two involved interviews with the authors of eight of the above mentioned textbooks to determine authors' views on analogies and their use in textbooks and teaching. The study identified a relationship between how frequently analogies were used by the author and what he or she considered to be the characteristics of a good chemistry teacher. Each author had a good understanding of the nature of analogy and each sought a flexible environment for its use - most arguing that analogies are better used by teachers than printed in textbooks. They appeared to favour analogies embedded in text or placed in margins rather than as post-synthesisers or advance organisers.Study Three reports an investigation into six chemistry teachers' use of ++ / analogies in Western Australia and England. This study found that the teachers drew upon their experiences and professional reading as sources of the analogies that tended to be spontaneously used when they felt their students had not understood an explanation. The analogies tended to map functional attributes of abstract target concepts with some teachers using the blackboard to illustrate pictorial analogies and some including statements of limitations.Study Four describes the development of analogy maps - instruments used to determine the effectiveness with which students map given analogies. The iterative development process engaged classroom-based research methods to develop an instrument of value both for teaching and for school-related research. A rating system enables researchers to compare students' effectiveness at mapping analogies with variables such as analogy type.Studies Five and Six describe how a combination of interviews and analogy map surveys were used to investigate how students used analogies in chemistry. The study found that students felt more confident with pictorial-verbal analogies although they were not necessarily able to map these analogies better than verbal (only) analogies. Also, student mapping confidence appeared not to depend upon the level of enrichment supplied and added enrichment did not necessarily aid mapping performance. Further, the analogy maps were useful as a means to identify alternative conceptions and there was little evidence that the analogy maps contributed to the formation of alternative conceptions in the learners.The final chapter draws together and discusses the assertions made in all of the previous studies before considering the contribution of the thesis to theory building. The implications of the research are discussed and suggestions made for future research on analogies in chemistry education. The chapter ++ / concludes by outlining examples of how and where the findings of this research have begun to be disseminated.
