The difficulties and challenges in a Precalculus class: an ethnographic study
Mathematics. Education. Digital Technologies.
The Precalculus course is aimed at filling the mathematical knowledge gaps of the Basic Education students and prepare them to follow the specific contents of Calculus. However, despite being a component of preparation for the Calculus course, students have also demonstrated difficulties in this new discipline. The purpose of this research is to comprehend the students’ difficulties in a Precalculus discipline. To do so, an ethnographic study was carried out in a Precalculus class at a Mechanical Engineering course, a literature review of work on the Precalculus theme and the search for Digital Information Technology and Communication (DITC) resources that could aid students of Precalculus. Through the ethnographic study, it was possible to observe that some students showed apprehension to expose themselves, (dis)interest in the curricular component, excessive mobile phone use, and difficulty to keep a study routine concerning the Precalculus. The present research is supported by post-structuralist authors. The outcome of this research refers to a Digital Educational Resource (DER), in the format of a digital book (e-book), which aims at presenting DITC and tips to insert these technologies in Precalculus classes based on the difficulties found in the ethnographic study carried out. The product was developed on the platform Canva. The choice for this format is an attempt to share DITC and tips on how to use it, so that DER becomes an alternative to professors, in order to think or rehearse the execution of collective experiences focused on the establishment of relations, cooperation practice, promotion of new interests, student preparation practice, as well as the study supported by DITC.
