No campo da química, a escrita precisa transitar entre os níveis macroscópico, submicroscópico e o representacional, utilizando-se de elementos específicos da linguagem e do contexto no qual a linguagem é produzida. Modelos de análise baseados na Linguística Sistêmico Funcional, um que analisa a construção do campo, e outro que analisa a construção de entidades dentro da semântica discursiva foram utilizados para analisar a escrita de estudantes de graduação em química. Nosso objetivo foi avaliar se estes modelos podiam ser aplicados a textos de química produzidos pelos estudantes, identificando escolhas linguísticas utilizadas na produção textual, mapeando entidades específicas do campo da química e realizar adaptações nos modelos avaliados de forma que se adequem ao contexto da Química. O corpus de análise foi constituído de 31 textos divididos em três grupos de experimentos em química orgânica. Para cada grupo, foram mapeados elementos relacionados ao campo (relações taxonômicas, tipos de atividades e propriedades) e elementos da linguagem (entidade, dimensionalidade e metáforas gramaticais vivas). A análise dos textos mostrou que os estudantes têm dificuldades em descrever o campo da química no mundo submicroscópio e isso impacta na construção de taxonomias e nos tipos de atividades descritas. O mapeamento de entidades indicou que a diversidade das entidades depende diretamente do tipo de experimento e ainda que os estudantes não constroem metáforas gramaticais vivas. Portanto, os modelos de análise adotados neste artigo podem ser utilizados para analisar textos produzidos pelos estudantes de química. No entanto, os textos aqui analisados se referem a uma área específica da química, a química orgânica. Um desdobramento desta pesquisa seria estender este estudo à outras áreas da química.
