Item Análise de material didático para a abordagem de questões sociocientíficas (QSC) na perspectiva de professores de Química da educação básica(2024-07-25) Silva, José Jonas da; Firme, Ruth do Nascimento; http://lattes.cnpq.br/7234636790850019; http://lattes.cnpq.br/4208955531756095The approach to Socioscientific Issues (CSQ) in science teaching enables students to discuss social, environmental and economic issues, of a controversial nature and related to science, in the school context. This approach enables the contextualization of school content from the perspective of citizen science. Therefore, the objective of this research was to analyze the contributions and limitations of a didactic material developed for the implementation of the approach of Socioscientific Issues in the teaching of Chemistry from the perspective of Chemistry teachers in Basic Education. Five methodological stages were developed: literature review (stage 1); preparation of didactic material for the implementation of the approach to Socioscientific Issues in the teaching of Chemistry (stage 2); preparation and application of the questionnaire for the evaluation of the didactic material prepared (stage 3); teacher evaluation (stage 4); organization, systematization and analysis of data (step 5). A qualitative approach to the data was adopted (Minayo, 2004). Four basic education chemistry teachers participated in the research. The teachers identified contributions and limitations of the didactic material entitled: "A proposal for the approach of the socio-scientific question The dilemma of automobiles: fuel versus battery from the mock jury as a didactic strategy", such as: allowing a connection between the QSC and Science; having the Socio-Scientific Question as the central focus of the proposal and the QSC being approached as a real-world context and allowing discussion on social dimensions of science (contributions); not ensuring the participation of all students in higher-order practices (argumentation, reasoning and decision-making); the level of previous knowledge of the students about the QSC and stage 5 as the only moment for the discussion of scientific content in the Practices of confrontation of scientific content with the Socioscientific Question (limitations).Item Estudos de cinética química a partir da elaboração e uso de uma cartilha didática sobre produtos de limpeza para lavagem de roupas(2023-09-18) Nascimento, Ismani Adalgiza do; Amaral, Edenia Maria Ribeiro do; http://lattes.cnpq.br/5241130686153506; http://lattes.cnpq.br/0285664573551889The present study deals with the development and validation of a booklet that contains concepts of chemical kinetics, presented from the action of sanitizers for clothes washing. The objective of this study is to analyze the potential and limitations of the booklet, as well as to verify the participation and interaction of students during the use of the material and to evaluate how the association of the action of sanitizers to the concepts of chemical kinetics can help students understand this subject. In order for the work to be developed, after the development of the booklet, a didactic sequence composed of three moments was proposed: raising the students' previous conceptions, teamwork using the booklet and application of the final questionnaire. Through the application of this sequence, some results were obtained: Most of the students were able to conceptualize what chemical kinetics studies after the teamwork using the booklet, in addition, they associated the study of the reaction speed to other examples of everyday life, not limited to the situation presented about the action of sanitizers for clothes washing. Some potentialities of the booklet identified by the students were: accessible and clear language of the text, promotes interactivity and is playful. In addition, the students made suggestions to improve the content of the booklet: use fewer formulas, discuss more theories, and expand the approach of other subjects. With the results, it was possible to realize that the booklet is an attractive material that can be used as a pedagogical support material, containing various subjects in a playful and interactive way.
