Resumo: | The teaching by Transmission-reception corresponds to an insistent reality in Chemistry classrooms, stigmatizing teachers as active subjects in the teaching and learning process while students behave as mere recipients of the contents that are often not articulated with the social contexts in which they are inserted. Intending to contribute to change this scenario, many researchers in Chemistry teaching work to develop and popularize the so-called active teaching methodologies, aiming to prepare teachers to act as mediators of the teaching and learning process, enabling the protagonism of students. In this sense, the teaching by using problem solving represents a valuable strategy that enables the articulation of chemical knowledge with the students' reality, inserting them in scientific research activities in the school context, valuing the problematization, hypothesis elaboration, reflection, debates and the teacher's mediation. Investigations on the teaching and learning of Electroplating point out such content as one of the subjects of greatest difficulty for students to understand. Thus, this research contributed to the construction of concepts related to Electroplating based on Problem-Solving, making use of a teaching and learning sequence. The research subjects, thirty-four high school students from a state school in the metropolitan region of Recife, underwent a diagnostic evaluation containing questions related to the central theme and both the answers of this first evaluation and the answers given as a resolution to the proposed problem were analyzed qualitatively, with a descriptive/interpretative character, aiming to identify the construction of knowledge at a phenomenological, theoretical and representational level. After applying the teaching and learning sequence, it was acknowledged that most students were able to develop the learning of Electroplating in at least two of the three expected levels of chemical knowledge, and it was found that students were able to restructure knowledge to respect the concepts explored in the initial evaluation, especially in relation to the formation of rust, since the students revealed to know it only empirically when they elaborated their answers based on reasoning that took into consideration only the macroscopic observations they had made at some point in their lives. Thus, in addition to verifying the efficiency of the educational product built in this work, a contribution was developed to make it even more evident that the construction of concepts about Electroplating is favored by the problem solving methodology. |

Pretendendo contribuir com a mudança desse cenário, muitos pesquisadores em ensino de química trabalham para desenvolver e popularizar as chamadas metodologias ativas de ensino, visando preparar os docentes para que atuem como agentes mediadores do processo de ensino e aprendizagem, possibilitando o protagonismo aos estudantes. Nessa direção, o ensino por Resolução de Problemas representa uma valiosa estratégia que possibilita a articulação do conhecimento químico com a realidade dos alunos, inserindo-os em atividades de investigação científica no contexto escolar, valorizando a problematização, elaboração de hipóteses, reflexão, debates e a mediação do professor. Investigações a respeito do ensino e aprendizagem sobre Galvanoplastia apontam tal conteúdo como um dos assuntos de maior dificuldade de compreensão por parte dos alunos. Dessa maneira, a presente pesquisa contribuiu para a construção de conceitos relativos à Galvanoplastia a partir da Resolução de Problemas, fazendo uso de uma sequência de ensino e aprendizagem. Os sujeitos da pesquisa, trinta e quatro alunos do segundo ano do Ensino Médio de uma escola estadual da Região Metropolitana do Recife, foram submetidos a uma avaliação diagnóstica contendo questionamentos correlatos à temática central e tanto as respostas dessa primeira avaliação quanto as respostas dadas como resolução ao problema proposto foram analisadas de modo qualitativo, com caráter descritivo/interpretativo, objetivando identificar a construção do conhecimento em nível fenomenológico, teórico e representacional. Após a aplicação da sequência de ensino e aprendizagem, constatou-se que a maioria dos alunos conseguiu desenvolver a aprendizagem relativa aos conceitos de Galvanoplastia em pelo menos dois dos três níveis de conhecimento químico esperados. Também percebeu-se que os alunos conseguiram reestruturar o conhecimento a respeito dos conceitos explorados na avaliação inicial, sobretudo com relação à formação da ferrugem, pois os estudantes revelaram conhecê-la apenas empiricamente, quando elaboraram as suas respostas a partir de raciocínios que levavam em consideração apenas as observações macroscópicas que tinham realizado em algum momento de suas vidas. Assim sendo, além de verificar a eficiência do produto educacional construído neste trabalho, desenvolveu-se uma contribuição para deixar ainda mais evidente que a construção de conceitos sobre Galvanoplastia é favorecida pela metodologia de resolução de problemas.Submitted by Mario BC (mario@bc.ufrpe.br) on 2022-04-12T14:54:44Z No. of bitstreams: 1 Rafael Jose dos Santos.pdf: 2274931 bytes, checksum: 1e04842d8c1526ef8ee8d028dc05c4a5 (MD5)Made available in DSpace on 2022-04-12T14:54:44Z (GMT).

The teaching by Transmission-reception corresponds to an insistent reality in Chemistry classrooms, stigmatizing teachers as active subjects in the teaching and learning process while students behave as mere recipients of the contents that are often not articulated with the social contexts in which they are inserted. Intending to contribute to change this scenario, many researchers in Chemistry teaching work to develop and popularize the so-called active teaching methodologies, aiming to prepare teachers to act as mediators of the teaching and learning process, enabling the protagonism of students. In this sense, the teaching by using problem solving represents a valuable strategy that enables the articulation of chemical knowledge with the students' reality, inserting them in scientific research activities in the school context, valuing the problematization, hypothesis elaboration, reflection, debates and the teacher's mediation. Investigations on the teaching and learning of Electroplating point out such content as one of the subjects of greatest difficulty for students to understand. Thus, this research contributed to the construction of concepts related to Electroplating based on Problem-Solving, making use of a teaching and learning sequence. The research subjects, thirty-four high school students from a state school in the metropolitan region of Recife, underwent a diagnostic evaluation containing questions related to the central theme and both the answers of this first evaluation and the answers given as a resolution to the proposed problem were analyzed qualitatively, with a descriptive/interpretative character, aiming to identify the construction of knowledge at a phenomenological, theoretical and representational level.
