Abstract
The focal point of this research was the potentiality of the Case Study Teaching Strategy (CSTS) for teaching High School Chemistry. To do this, CSTS was applied by three Chemistry teachers in a public school in Brazil. As research instruments, we used classroom observation, application of a questionnaire to the students and a semi-structured interview with the teachers. The results indicated that, according to teachers and students, CSTS is a favourable and significant teaching tool for High School. These subjects pointed out the emphasis in the active and analytical participation of students, group work, acquiring of different scientific knowledge, approaching the content from the student's experience, stimulation of the development of important abilities by the students, such as reading, argumentation, oral communication, among others. They also pointed out difficulties involved in the application of CSTS, such as time and the lack of resources for the research.
