AbstractDesigning problems and learning activities is a key factor to initiating students’ engagement with the course material and influencing their reasoning processes. Although tasks and problems are a central part of teaching and assessments in the chemistry classroom, they may not engage students in deep reasoning or in a way that is intended through a task. Some problems may cause an algorithmic or a surface approach. Even with designing clever problems, students may not use a larger variety of chemistry ideas and connect them in meaningful ways. Here the idea of scaffolding students’ answering process comes into play. Structuring students’ reasoning process through instructional prompts or structured worksheets supports students in activating and connecting knowledge pieces in a more meaningful way and positively slows down their fast decision-making process. This paper will discuss the importance of asking questions in chemistry teaching and highlights the idea of contrasting cases, drawn from cognitive psychology, as a task design principle. In addition to having contrasting cases as a good problem format, the idea of scaffolding students’ reasoning while solving contrasting cases through the use of instructional prompts that scaffold the reasoning process will be exemplarily showcased for mechanistic reasoning in organic chemistry.

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.

Organic Chemistry is one of the difficult subjects, especially in reaction and strechochemical mechanisms. One effort to reduce it is to utilize teaching materials. This study aims to develop organic chemistry teaching materials on free radical reaction material in the form of constructivism-based student worksheets (LKM). The research method used research and development research design with a 4D development model which consists of the stages of define, design, development, and disseminate. Development of LKM was assessed based on validity criteria and limited trials. The validity of LKM was achieved and assessed by three validators. Limited trials were conducted for the 6th semester students of the chemical education study program totaling 15 people and also three organic chemistry lecturers to see the appropriateness of developed LKM from the lecturers' perspective. The overall LKM results of its validity showed that the LKM has 95.05% valid. The results of limited trials based on the responses of students and lecturers each obtained a percentage of 84.02% and 87.22%, respectively. Based on the results of validation and limited testing of constructivism-based LKM on the material of free radical reaction developed it is included in the category of valid and can be used in the learning process.
