No. of bitstreams: 1 5122.pdf: 4836185 bytes, checksum: e68b829c8c97de590e305d990e8a1452 (MD5) Previous issue date: 2012-04-13 / Secretaria da Educação do Estado de São Paulo / This paper describes the development of experimental activities with the aid of the microcomputer as a measuring tool in the laboratory teaching of physics, as well as an account of his experience in the classroom. Using the software Audacity activities were carried out involving acoustic wave phenomena and as an aid for the development of a significant learning in high school. As theoretical references were used sociointeractionist theories of Vygotsky and Ausubel's meaningful learning. The instructional material was applied to two groups of high school students: a State School Marechal Rondon - Guara / SP and other College Evolution - Guara / SP. The learning experience is described in this paper and the product was produced education tours for student experiments. / O presente trabalho descreve o desenvolvimento de atividades experimentais com auxílio do microcomputador como instrumento de medida no laboratório didático de Física, bem como um relato desta experiência em sala de aula. Com auxílio do software Audacity foram desenvolvidas atividades envolvendo fenômenos ondulatórios e a acústica como meio auxiliar para o desenvolvimento de uma aprendizagem de forma significativa no ensino médio. Como referenciais teóricos foram utilizadas as teorias sociointeracionista de Vygotsky e a da aprendizagem significativa de Ausubel. O material instrucional foi aplicado a duas turmas de alunos de ensino médio: uma da Escola Estadual Marechal Rondon Guará/SP e outra do Colégio Evolução Guará/SP. A experiência didática é descrita neste trabalho e como produto educacional foram produzidos roteiros de experimentos para o aluno.

Ambiente virtual de aprendizagem em ondas e acústica para auxiliar o processo ensino e aprendizagem da física no ensino médio

Carmo, Rodrigo Salvadori Baptista do 03 February 2013 (has links)
Made available in DSpace on 2016-06-02T20:02:52Z (GMT). No. of bitstreams: 1 5280.pdf: 8210728 bytes, checksum: 25d41c9af014811f3c1f0f36883c9a32 (MD5) Previous issue date: 2013-02-03 / This work describes the development of a VLE Virtual Learning Environment, where music is the basis for studying sound waves. New educational tools such as videos, animations, simulations, as well as the Moodle platform, were used to create a virtual environment, where students can learn about sound waves in an autonomous and interactive way, motivating them to use computers and internet as facilitators of the teaching/learning process, making it more effective and interesting. This material was applied to High School students - which translates to Ensino Médio and/or Pré-Vestibular in Brazil s schooling system - in the following schools: Carlos Drummond de Andrade and Nomelini Cirandinha, both in Barretos, Escola Espaço Livre, in Bebedouro and Coc Cardiofísico, in Jaboticabal. Both the teaching experience related to the VLE construction and its learning results are also described in this work. / O presente trabalho descreve o desenvolvimento de um AVA Ambiente Virtual de Aprendizagem, onde utilizamos a música como fio condutor para o estudo das ondas sonoras. Fazendo uso das novas ferramentas educacionais como vídeos, animações, simulações bem como a plataforma Moodle, produzimos um ambiente virtual onde os alunos podem estudar as ondas sonoras de uma forma interativa e autônoma, incentivando-os a utilizar o computador e a internet como facilitadores do processo de ensino/aprendizagem, tornando este processo mais efetivo e interessante. Esse material foi aplicado a turmas de alunos do Ensino Médio e Pré-Vestibular das escolas Carlos Drummond de Andrade e Nomelini Cirandinha, ambas de Barretos, Escola Espaço Livre, de Bebedouro e escola COC Cardiofísico, de Jaboticabal. Tanto a experiência didática quanto a construção do AVA e seus resultados de aprendizagem são também descritos neste trabalho.
