A ascensão e queda da teoria do calórico
The aim of this paper is to make a historical analysis of the appearance of the caloric theory, its explanatory power and its decline. Unlike many texts disclose, we will show that Joseph Black was not the first to investigate the heat as a substance and that the experiments of Benjamin Thompson (Count Rumford) were not crucial to the abandonment of this theory. The explanatory power of the caloric will be shown by analysis of extracts from the book of dissemination of Science authored by Janet Marcet. We believe that the knowledge of these facts will help to better understand the origin of many terms that we use in the study of the calorimetry, besides alerting teachers and students of the historical claims errors found in textbooks.
Do calórico ao calor: uma proposta de ensino de química na perspectiva histórica
E proposta uma sequencia didatica para a construcao do conceito de calor com base em trechos do livro Conversations on Chemistry, publicado no seculo XIX na Inglaterra por Jane Marcet. Os fundamentos teoricos que embasam o uso de historia da ciencia e da experimentacao no ensino de quimica sao apresentados. A aplicacao da sequencia didatica para uma turma de 1a serie do ensino medio e descrita e os resultados sao apresentados e discutidos, dentre eles, evidencias da apropriacao do modelo cinetico-molecular de calor pelos alunos e sua mobilizacao para explicar novas situacoes.
Educational innovation in Musical Language Course: responses and the overcoming of limitations
This article presents an innovative methodological proposal for the development of auditory education in the course of the Language of Music. Based on this proposal, we analyze an educational community’s response to the innovations implemented, and we identify the limitations recognized throughout the learning and teaching process, as well as the strategies developed to overcome them. To this end, we applied a qualitative methodology with the classroom-based research method. The compilation of data was carried out through participant observation, captured in the journals of the professor and researcher, interviews and analysis of documents. The research results demonstrate that patience, responsibility and perseverance in their work on behalf of the professors have been key to overcoming the limitations identified and in promoting that students enjoy and learn their class contents in meaningful ways.
