Relato de experiência de uma regência sobre estequiometria desenvolvida no ensino médio utilizando diferentes recursos: aprendizados e dificuldades

Abstract

The present work is an experience report of the conducting of a chemistry
teacher, developed within the Pedagogical Residency Program (PRP) of the
Federal University of Itajubá (Unifei). The PRP is a project that aims to
improve the training of the undergraduate student (intern) through
immersion in public schools of basic education, in which the undergraduate
student develops activities such as disciplinary and interdisciplinary projects
and lesson plans. This report contemplates the execution of a chemistry
lesson plan for a 2nd year high school class, through a differentiated
approach to the stoichiometry content, with technological resources and
practical experiments. The limitations and difficulties of proposing activities
using these resources in the classroom are also discussed. Stoichiometry is
the content of chemistry that studies the amount of substances involved in a
chemical reaction, the proportions between regents and formed products.
Students usually have some difficulties in understanding this content, mainly
due to problems with interpretation and mathematical calculations. Thus,
some types of approaches and resources, such as relating the content to the
daily lives of students and using simulators, can reduce the distance between
students and the content and help in learning. The development of
conducting classes contributed to the critical maturation of the intern,
making her initial training more effective.
