Na interpretação do mundo pelo viés das ferramentas da Química, é essencial que se explicite seu caráter dinâmico. Assim, o conhecimento químico não deve ser entendido como um conjunto de conhecimentos isolados, prontos e acabados, mas sim uma construção da mente humana, em contínua mudança. A História da Química, como parte do conhecimento socialmente produzido, deve permear todo o ensino de Química, possibilitando ao aluno a compreensão do processo de elaboração desse conhecimento, com seus avanços, erros e conflitos. Com o objetivo de integrar o uso da oralidade em sala de aula, a História da Química e conteúdos de Química Orgânica, foi proposto um trabalho com o gênero textual oral seminário sobre o livro “Os botões de Napoleão: as 17 moléculas que mudaram a história”, em uma turma de 3º ano do Ensino Médio, de um colégio estadual de uma cidade paranaense. Para o seminário, os alunos foram divididos em cinco grupos e cada grupo ficou com um capítulo para a preparação, organização e apresentação. Os capítulos escolhidos foram: pimenta, noz-moscada e cravo da índia, a glicose, o fenol, compostos nitrados e a pílula. Esses capítulos foram selecionados devido ao fato de estarem em consonância com os conteúdos bimestrais da disciplina de Química. O desenvolvimento do trabalho apontou o uso do seminário como um instrumento facilitador do Ensino de Química, que proporcionou a ampliação da competência oral dos alunos e a compreensão de conceitos químicos e históricos.Palavras-chave: Seminário. Ensino de Química. História da Química.AbstractIn interpreting the world through the bias of Chemistry tools, it is essential that its dynamic character be made explicit. Thus, chemicalknowledge should not be understood as a set of isolated, ready and finished knowledge, but a continually changing construction of the human mind. The Chemistry History, as part of the socially produced knowledge, must permeate all the Chemistry teaching, enabling the student to understand the process of elaboration of this knowledge, with its advances, errors and conflicts. In order to integrate the use of orality in the classroom, the Chemistry History and Organic Chemistry contents, a work was proposed with the oral textual genre seminar on the book “The Buttons of Napoleon: the 17 molecules that changed the History”, in a class of 3rd year of High School, of a state School in a city from Paraná State. For the seminar, students were divided into 5 groups and each group was given a chapter for preparation, organization and presentation. The chapters chosen were: pepper, nutmeg and cloves, glucose, phenol, nitrated compounds and the pill. These chapters were selected because they were in line with the bimonthly contents of the Chemistry discipline. The development of the work pointed to the use of the seminar as an instrument facilitating the Chemistry Teaching, which provided the students with increased oral competence and understanding of chemical and historical concepts.Keywords: Seminar, Chemistry Teaching, Chemistry History .

Resumo: Atualmente, existe uma preocupação em relação ao processo de ensino-aprendizagem de alguns conceitos científicos, como os conceitos iniciais de Química Orgânica, vistos no terceiro ano do Ensino Médio. Uma das alternativas para solucionar esse problema tem sido construir e apontar materiais didáticos para incrementar a metodologia das aulas ministradas pelos professores de Ciências. Alguns desses materiais, que podem contribuir com o êxito no processo de ensino-aprendizagem são os softwares lúdicos educacionais. Neste trabalho, apresentamos um aplicativo didático que foi desenvolvido, denominado Quiz Molecular, para dispositivos móveis, abordando o conteúdo de funções orgânicas. Além disso, relatou-se a aplicação, avaliação e validação do jogo com alunos de uma escola estadual de Ensino Médio e licenciandos em Química de uma instituição federal de ensino, utilizando-se questionários com perguntas objetivas e discursivas, em uma pesquisa qualitativa. Notou-se que o jogo proposto agradou aos alunos de Ensino Médio e aos futuros professores, demonstrando que pode ser uma boa alternativa para dinamizar as aulas de Química Orgânica.Palavras-chave: Tecnologias no Ensino; Ensino de Química; Química Orgânica. Abstract: Currently, there is a concern about the teaching-learning process of some scientific concepts, such as the initial concepts of Organic Chemistry, seen in the third year of high school. One of the alternatives to solve this problem has been to build and to point teaching materials to increase the methodology of the classes. Some of these materials, which can contribute to the success of the teaching-learning process, are educational software. In this work, an educational app for mobile devices was developed, named Molecular Quiz, and it addressed the content of organic functions.  It is also reported its application and validation with high school and graduation students. For theses analysis, it was used questionnaires with objective and discursive questions. It was noted that the proposed game pleased students and future teachers, demonstrating that it can be a good alternative to dynamize Organic Chemistry classes. In addition, the app has been validated as an educational game.Keywords: Educational Technologies; Chemistry teaching; Organic chemistry.

Pesticides are chemicals that aim to control pests in agriculture, livestock, and household cleaning purposes. The use of the theme as a guideline for working chemical concepts is of great interest in the field of Chemistry Teaching, especially when applied in the area of Environmental Chemistry, Analytical Chemistry and Organic Chemistry, as a major concern in Chemical Science, is the way how educators contextualize their specific subjects with their students. After conducting interviews with six chemistry teachers who teach in Chemistry Course, the theme pesticides was contextualized in the specific disciplines of the Course, using data supplied by teachers and by gathering information in scientific articles and books. By this all, an educational copybook was produced.

O presente estudo aborda as concepções iniciais de estudantes do 1º ano do Ensino Médio sobre a relevância do componente curricular de Química. Assim, o problema central da pesquisa é: Quais as concepções iniciais de estudantes do 1º ano do Ensino Médio sobre a relevância do componente curricular de Química?. A investigação foi realizada com estudantes de três turmas do 1º ano do Ensino Médio, totalizando 69 participantes, com idade média de 16 anos, pertencentes a uma escola pública estadual da região do Vale do Sinos, RS, Brasil. Para coleta de dados, o professor perguntou aos estudantes: Qual a relevância que você percebe na Química? Cabe ressaltar que o questionamento foi realizado por escrito na primeira semana de aula do ano letivo de 2016, antes do professor do referido componente iniciar o trabalho relacionado aos conteúdos para aquele ano. O material coletado foi analisado por meio de Análise Textual Discursiva (MORAES; GALIAZZI, 2013). A análise possibilitou compreender que os estudantes apresentam concepções distintas sobre a relevância do componente curricular de Química. Acredita-se que tais concepções tenham sido construídas por meio de vivências escolares, durante os anos anteriores de escolarização, e fortalecidas no 9º ano do Ensino Fundamental, onde o componente de Ciências aborda tópicos relativos à Química, ou ainda, a partir do cotidiano desses estudantes. Os resultados obtidos podem auxiliar os professores deste componente curricular no sentido de desenvolverem práticas mais efetivas que proporcionem aos estudantes compreender a real função e relevância do estudo da Química, enquanto ciência.Palavras-chave: Educação Básica.

Thus, the central problem of the research is: What are the initial conceptions of students of the 1st year of High School on the relevance of the curricular component of Chemistry? The research was carried out with students from three classes of the 1st year of High School, totaling 69 participants, with a mean age of 16 years, belonging to a state public school in the region of Vale do Sinos, RS, Brazil. For data collection, the teacher asked the students: How relevant do you perceive in chemistry? It should be noted that the questioning was done in writing in the first week of class in the 2016 school year, before the professor of chemistry began to work with the planned the course for that year. The collected material was analyzed through Discursive Textual Analysis, (MORAES; GALIAZZI, 2013). With the analysis it was possible to understand that the students pointed out different conceptions about the relevance of the curricular component of Chemistry. It is believed that such conceptions were constructed through school experiences, during the previous school years and emphasised in the 9th year of Elementary School, where the Science component covers topics related to Chemistry, or even, from the daily life of these students. The collected data can help the teachers from this subject to develop more effective practices that allow students to understand the real function and relevance of the study of Chemistry as a science.Keywords: Basic education.

Chemistry teaching is not such an easy task for teachers trained in contemporary times. The process of updating your resume should be a constant in the profession. The teacher needs to plan his classes with a language that can make it easier for the student to understand the contents explained. One of the ways of working with chemistry could be with the student actively participating in the process. Agrochemicals are feasible topics to be mediated in this way and can potentially increase students’ interest in the discipline. This article aims to identify the strategies for teaching chemistry at a high professional and technological level present in scientific articles with the theme “pesticides”. The methodology chosen for this study was a qualitative approach centered on being concerned with reality. The observation of this brief survey allows us to conclude that the teaching of chemistry in high school groups can and must be related to the area of ​​research and scientific dissemination; there are several didactic tools that enable more assertive ways related to teaching chemistry; and relating the content of chemistry to interdisciplinary and specific subjects, such as pesticides, can help a better understanding of the content of chemistry in high school students.

ResumoPrimo Levi, químico italiano, participou da resistência italiana, e, judeu, foi capturado e levado a Auschwitz. Ao fim da segunda guerra mundial, retomou suas atividades na indústria, e iniciou a de escritor. Em suas memórias do Holocausto, a Química, seus elementos, e as habilidades necessárias nas suas práticas servem de fios construtores. Se a História da Ciência se constitui como uma área de interface, ela é interdisciplinar e, o livro A Tabela Periódica, como leitura contextualizada do período, mescla elementos históricos e científicos que permearam a construção do conhecimento. Por meio da leitura, a Química deixa de ser apenas ciência e se torna vivência. A Química, a matéria e suas transformações se tornam uma lente de mundo. A leitura de dois capítulos do livro foi mediada junto a alunos do terceiro ano do Ensino Médio. O objetivo foi compreender a possibilidade de emprego de sua leitura na formação de alunos do ensino médio, visando a interdisciplinaridade e despertar o interesse pela leitura. Observamos desconhecimento básico sobre acontecimentos recentes da história da humanidade, dificuldades na interpretação de texto, contudo percebemos após a leitura guiada dos dois capítulos uma melhor interpretação e compreensão dos fatos.Palavras chave: História da Ciência; História da Química; Ensino de Química; Primo Levi.  AbstractPrimo Levi, an Italian chemist and Jewish men that had been a part of the Italian résistance movement, was captured and taken to Auschwitz during the World War II. After the war, he resumed his activities in the chemical industry and started a career as a writer. In his memories about the Holocaust, Chemistry, its elements and the abilities needed to its praxis, serve as conducting wire. If History of Science is an interface area, it is also interdisciplinary and his book, Periodic Table, as contextual reading of the period, has both historical and scientific elements that contribute to the construction of knowledge. Through the reading Chemistry is no longer just a science, it is experience. Chemistry becomes a lens through which to see the world. The reading of two chapters of the book was mediate amongst two different high school classrooms. The goal was to understand the possibility to use the reading in high school Education, aiming interdisciplinary formats and to promote the habit of reading. It was observed a lack of knowledge about recent events in human history and difficult to read the text, but it was also observed an improvement of both throughout the activity.   Keywords: History of Science; History of Chemistry; Chemistry Teaching; Primo Levi.

The aim is to present the relations between the teachings of Paulo Freire on the dialogical education and concerns with the teaching of chemistry, which is present in many natural events and transformations of matter in our daily lives, but witnessed an erosion of the teaching of it. We seek improvements in education, and why not go back to what Freire taught us? An education for dialogue, where the student becomes part of the school context. The dialogic be brings with it the commitment by the transformations of reality (FREIRE, 1983), and the dialogue, according to Freire Ibid p. 28, "the rendezvous of men, mediated by the world," pronounced ", I call it, transform it, and turning it, the humanize for the humanization of all", inspired and motivated a different education that We, in which changes are valuable and necessary. Using the trial as a facilitator of chemistry teaching, it takes an inductive space in student learning, being a kind of the same features that can control variables and discover or rediscover evidence and checks on the theories studying, taking this case a deductive character to test what is described theoretically.

The COVID-19 pandemic has impacted every aspect of life around the world. Colleges and universities were forced to close and shift to remote/distant/online learning.  This event resulted in classes being delivered online, prompting faculty in different chemistry departments to ponder on several questions. How can we maintain the same engagement we have in a face-to-face environment once we go online? Are we ready for this mode of teaching? How are we going to do the laboratory class? This same set of questions posed a challenge to me when the institutions I am teaching decided to shift on remote/distance learning. In this paper, I share my experiences on how we transition to this new teaching mode. Among these experiences include the preparations in classes (both lecture and laboratory) and the resources that I used. I will also discuss the preparation I made for my students and the reactions I got from them as we went on transition and by the end of the semester. I hope that this paper will be helpful to the readers (college and high school faculty) as they prepare for flexible learning once classes resume in the Philippines.
