Resumo
Esta pesquisa objetivou investigar se licenciandos em química enunciam e compreendem os conceitos de aleatoriedade e irreversibilidade, presentes na Teoria Cinética dos Gases, por meio de etapas construídas para um jogo digital e da sua aplicação após finalizado. Participaram da pesquisa vinte e um acadêmicos do curso de licenciatura em química de uma universidade tecnológica federal no Paraná, separados em: grupo 01, 02 e 03. Para a coleta de dados, cada grupo, em determinados momentos, respondeu questionários, elaborou desenhos e participou de entrevistas semiestruturadas. O desenvolvimento da pesquisa foi orientado pela abordagem qualitativa e por alguns estudos realizados por Piaget. Para tratar e analisar os dados, optamos pelos princípios da análise de conteúdo. A partir do conteúdo dos desenhos construídos nas etapas do jogo digital, foi possível constatar que, os participantes do grupo 01 e 02 buscaram ilustrar em alguma etapa do jogo, uma aproximação de distribuição homogênea do sistema. Nos desenhos dos níveis, verificamos que a maioria (quatorze) dos participantes levou em consideração as experiências obtidas durante o jogo, porque mudaram a maneira de prever em algum nível, as trajetórias de partículas no sistema; dentre os vinte e um sujeitos, apenas oito ilustraram nos quatro níveis do jogo, as primeiras previsões de colisões do lado esquerdo, alcançando o padrão de análise estabelecido. No conteúdo obtido nos discursos dos participantes, referente ao conceito de irreversibilidade, foi possível verificar que este conhecimento não está bem construído nas estruturas cognitivas dos participantes do grupo 01 e 02, porque cinco apresentaram discurso não elucidativo nas quatro etapas do jogo e dois não souberam elucidar o conceito investigado em três etapas. Com relação ao conceito de aleatoriedade, verificamos que os participantes utilizaram palavras diferentes em cada contexto de aplicação das etapas e dos níveis do jogo digital, apresentando distintos discursos, como de gênero científico, próximo do gênero científico, de senso comum, não elucidativo e elucidativo ao jogo. Depreende-se que os recursos didáticos digitais utilizados podem proporcionar aos estudantes compreenderem e apreenderem conteúdos de caráter microscópico e submicroscópico. Portanto, as etapas e os níveis do jogo digital poderão contribuir para que os sujeitos apreendam cientificamente os conceitos da teoria cinética dos gases, como também em outras áreas do conhecimento.
This research aimed to investigate whether licentiate in chemistry enunciate and understand the concepts of randomness and irreversibility present in Kinetic Theory of Gases, through the construction of steps of a digital game and its application after finalized. The participants were twenty-one academics in chemistry degree course of a federal technological university in Paraná, separated into: Group 01, 02 and 03. For the collection of data, each group, at certain times, answered questionnaires, prepared drawings and participated in semi-structured interviews. The development of the research was guided by a qualitative approach and some studies conducted by trough the ideas of Piaget. To process and analyze the data, we chose the principles of content analysis. From the content of the drawings built on the steps of digital game, it was found that the participants of group 01 and 02 sought to illustrate in some stage of the game, a homogeneous distribution approach of the system. In the drawings levels, we found that the majority (fourteen) of the participants took into account the experiences gained during the game because it changed the way to predict to some degree, the particle trajectories in the system; among the twenty-one subjects, only eight illustrated in the four levels of the game, the first predictions of collisions on the left side, reaching the established pattern analysis. The content obtained in the speeches of the participants, referring to the concept of irreversibility, it was found that this knowledge is not well built in cognitive structures of group members 01 and 02, because five had not been elucidated speech in the four stages of the game and two did not know how to elucidate the concept investigated in the three steps. Regarding the concept of randomness, we found that participants used different words in each application context of the stages and the digital game levels, with different speeches, as scientific genre, close to the scientific genus, common sense, not enlightening and instructive the game. It appears that digital teaching resources used can provide students understand and grasp microscopic and submicroscopic character content. Therefore, the steps and levels of the digital game can contribute to the subject scientifically seize the concepts of kinetic theory of gases, as well as in other areas of knowledge.
