A utilização das técnicas de química forense como uma proposta de ensino de Química

Abstract

Forensic Chemistry is an area that has many connections with several other sciences and has great importance in the solution of criminal investigations. Chemistry teaching has been changing and new methodologies aim to relate Chemistry to the student's daily life. Students consider chemistry one of the most difficult subjects. In this way, to reduce these difficulties new teaching methodologies are used. This work has the general objective of carrying out a literature review on the theme Forensic Chemistry and its techniques as a teaching proposal. In addition, it seeks to recognize the importance of Forensic Chemistry methods for learning, to list Forensic Chemistry methodologies used as a teaching method, to emphasize the methods of Forensic Chemistry most frequently used in teaching. To achieve these objectives, a qualitative bibliographic research was carried out on several database that deal with the topic Forensic Chemistry. The results showed that the fictional crime scene and questionnaires are didactic resources very explored in the studied articles and that high school students are the focus of study. The authors point out the interdisciplinary as of great importance, since it is present in the most diverse areas of the forensic science. Chemical reactions and intermolecular forces are the most discussed contents in the articles under study. In addition, it can also be observed that the most used forensic chemistry techniques for didactic purposes were blood identification, chromatography, DNA extraction, fingerprint development and ballistics. At the end of these searches, it is possible to verify the importance of the subject studied and the great need to produce more research in the area so that it can reach more and more teachers, researchers and students
