Resumo: Energy is one of the key ideas of school science curricula. Research literature about students understandings of energy is ample, but concerned only with the identification of alternative conceptions. Learning about energy is considered difficult, for a number of reasons: it s too abstract, mysterious, the term of energy is confused with force and power, and energy is not used in the same way in the other scientific disciplines such as chemistry and biology, not to mention everyday language. Learning what energy means in physics demands abstraction and specialized knowledge of mechanics, electricity, thermodynamics, and other subjects. This work reports part of a research project in which we developed a didactical sequence to teach energy to year 9 (high school) secondary school students. We developed a learning environment to help students in making explicit and revise their understandings through collaborative work and discussions during their classes. In this work we present only students models of energy identified just before instruction.

A literatura sobre o tema é extensa, mas pouco esclarecedora. O tema é considerado como difícil de ser ensinado e aprendido, por ser usado em várias disciplinas que enfatizam usos e aspectos distintos do conceito. A idéia de energia é também amplamente utilizada na linguagem cotidiana, confundindo-se com idéias como as de força e potência. A aprendizagem do significado de energia em Física requer abstração e conhecimentos específicos de suas várias áreas, como mecânica, eletricidade, termodinâmica. Este trabalho relata parte de uma pesquisa desenvolvida no escopo de um projeto mais amplo, em que desenhamos uma seqüência didática para o ensino de energia para estudantes do primeiro ano do ensino médio de uma escola pública. Desenvolvemos um ambiente de aprendizagem para auxiliar os estudantes a explicitarem e revisarem seus modelos de energia , incentivando o trabalho em grupo e discussões em sala de aula. Aqui analisamos apenas os modelos de energia dos estudantes que identificamos na fase preliminar à intervenção que desenvolvemos e implementamos.Imprensa Universitária - UFSC2008-09-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/fisica/article/view/6275Caderno Brasileiro de Ensino de Física; v. 23 n. 2 (2006); 182-2172175-79411677-2334reponame:Caderno Brasileiro de Ensino de Física (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/fisica/article/view/6275/12765Barbosa, João Paulino ValeBorges, Antônio Tarcisoinfo:eu-repo/semantics/openAccess2022-11-29T18:35:52Zoai:periodicos.ufsc.br:article/6275Revistahttp://www.periodicos.ufsc.br/index.php/fisicaPUBhttps://periodicos.ufsc.br/index.php/fisica/oaicbefisica@gmail.com||fscccef@fsc.ufsc.br|| cbefisica@gmail.com2175-79411677-2334opendoar:2022-11-29T18:35:52Caderno Brasileiro de Ensino de Física (Online) - Universidade Federal de Santa Catarina (UFSC)false
