O uso de ACDLABS/CHEMSKETCH como ferramenta auxiliar no desenho de estruturas químicas, estereoquímica e reações orgânicas

Abstract

The present work presents an experience of an intervention in a school environment in high school, in the discipline of organic chemistry. In our actions in the initial and continuing education of chemistry teachers, we have worked for a scientific education that emphasizes the need to contextualize chemical knowledge in the classroom, making it useful for the education of citizens. Del Pino et al. (1993) states that it is the application of knowledge that seeks to facilitate the understanding of chemical phenomena, and allows bringing chemistry teaching closer to the student's context and as a result motivation for the construction of their knowledge in the school environment. Starting from the need that many students have difficulty, in the 2nd year of integrated teaching of basic organic chemistry at IFAM (design of organic reactions), especially in practice reports, we sought to minimize this problem, with the proposal of using a chemsketch software for drawing molecules in chemistry, bringing up subjects used in organic chemistry. Most students have many difficulties when designing their organic structures, and as a result their reports are poorly structured, with images of dubious origin and often without a chemical incoherent design. Therefore, the research had as its subject: 2nd year students of Integrated High School in Chemistry at IFAM, Campus Manaus Centro, and the objective: To teach students the use of chemsketch software to be used as an auxiliary tool in the design of structures and compounds as well as their 3D structures. The methodology used was an online presentation of the step by step of using the software as an educational technological tool, easy to access and free to download. The results were obtained through forms and from the answers of this research, it can be said that the use of the educational software chemsketch allows students to acquire learning in an easy and contextualized way, helping in the construction of their knowledge and, concepts that , most of the time, they are new and difficult to understand and, mainly, visualization. It is expected that all students in integrated chemistry teaching at IFAM will have access to this software and use it in all their reports.
