In the traditional model of teaching, when proposing a study on the properties of ceramic materials in undergraduate courses, one always starts from the study of the raw materials and types of ceramic materials, and after think about the properties, the applications and the processing. However, the inverse path of study, considering first the applications and processes to later arrive at the types of ceramics and the raw materials, is an alternative in the chain of the construction of knowledge, since one can first contextualize the technological importance of products and processes to reach the material itself and its possible raw materials. In the current educational context, varying the way of teaching using various alternatives and activities is very important in order to reach most students. Thus, the present work reports the study of an alternative for the teaching of the properties of silicon oxide from microelectronic process analyzes, starting from the several possible processes of obtaining the silicon oxide used in devices in microelectronics, and to explore its properties and possible sources of raw material. With this teaching methodology one can elicit the students' curiosity about the properties of materials from an initial knowledge of microelectronic technology. The present study was carried out during the offering of the subject "Design of Devices" at UFABC. Thus, students were challenged to think about the importance of certain ceramic materials for the development of technologies, in an interdisciplinary, reflective, dialogic and transformative context. Group activities, research activities and problem solving activities were conducted in the classroom based on this methodology and revealed a better learning about silicon oxide.
