Item Proposta de uma sequência didática baseada no ensino por investigação para abordar o conteúdo de eletrólise no ensino médio(2019-07-19) Oliveira, Johnies Jaaziel Matias de; Freitas, Kátia Cristina Silva de; http://lattes.cnpq.br/5859266863241551; http://lattes.cnpq.br/1186652030834689This word focuses on the proposal and analyses of a didactic sequence on the theme “Battery”. The sequence was elaborated for the development of the electrolysis contends in class of the 2nd or 3 and year of high school. The following methodological procedure was adopted: 1) Development of the Didactic Sequence on the theme Battery, 2) Analysis of the process of elaboration of the didactic sequence. The results show that the structure of the didactic sequence present characteristics teaching through research and bring elements of the dimensions of the epistemic and pedagogical. We have evaluated that this didactic sequence, because its contextualization in a daily theme, allows the students to have a more active participation, generating discussions and debates based on problems, questionnaires and experimental activities. Finally, this sequence also leads to environmental awareness of the incorrect disposal of batteries and their risksItem Atividade experimental em eletrólise para o ensino de química: abordagem para uma educação ambiental na escola(2018-08-17) Silva, Thiago Ramos da; Freitas, Kátia Cristina Silva de; http://lattes.cnpq.br/5859266863241551; http://lattes.cnpq.br/3205312853023513This work aims to analyze if the use of experimental activity in electrolysis, contextualized by environmental issues, will bring to the students of high school a more comprehensive understanding on the subject in the classes of chemistry. For this, the following methodological procedure was adopted: 1) research with teachers from the State of Pernambuco about how they analyze the electrolysis experiment, as a didactic resource to be developed in the classroom; and 2) construction of didactic planning and application of a Didactic Sequence (SD) on the electrolysis theme. The present study was based on a descriptive and exploratory qualitative analysis, where the data obtained served as a personal parameter to answer the questioning of the objective mentioned above. All the data made with the teachers in this research, after being processed, were constructing the idea for a relevance of the topic related to environmental awareness, since this transversal theme should be present in the educational process of students at various school levels, as recommended by the National Policy on Brazilian Environmental Education and the National Curricular Parameters. In order to construct students' knowledge in a well-planned way, the application of SD was divided into two moments: theoretical lecture on some topics of electrochemistry, whose emphasis was mainly on learning the electrolysis subject; and next, an experimental class in the room about electrocoagulation, using easily accessible materials. The verification of the phenomenon occurred in the experiment had as fundamental characteristic the use of electrolysis for water treatment purposes, using iron electrode in a hypothetical sample of a solution containing dyeing paint for clothes.
