Title: Estudo do movimento bidimensional realizado por uma esfera sobre um plano inclinado Author(s)/Inventor(s): Coelho, Miguel Nogueira de Carvalho Advisor: Soares, Vitorvani Abstract: In this work, we present a didactic activity to be carried out by students, with teacher mediation, to describe the two-dimensional movement of a sphere along an inclined plane. We constructed the geometric curve that depicts the trajectory of this sphere on the plane, with the help of experimental data extracted from a video produced by us. Then, we also present different geometric and algebraic methods to compare the experimentally obtained curve with those theoretically predicted by the parabolic movement. The teacher’s guide produced by this work offers an opportunity to present students with different ways to describe and analyze physical phenomena with accessible mathematical formulation, as demonstrated by its application with students of 3rd series of high school in a private school in Rio de Janeiro.

Title: Constantes fundamentais e análise dimensional no ensino médio Author(s)/Inventor(s): Carvalho, Humberto de Advisor: Moreira, Ildeu de Castro Abstract: Fundamental constants are not given this name by chance: they play a central role in connecting the micro and the macro, linking the classical, relativistic, and quantum worlds. They form the basis for building a sound intuition about the scales of nature. These constants are also essential elements for one of the most powerful tools in Physics: dimensional analysis. More recently, their relevance has become even more evident, as the entire International System of Units (SI) is now defined in terms of these fundamental constants. This dissertation aims to discuss how these constants are addressed in PNLD textbooks and in the daily practices of high school classrooms. To this end, a survey was conducted on the presence and treatment of fundamental constants in these works, as well as a questionnaire with Physics teachers from different regions of Brazil. Based on these data and the conclusions obtained, a booklet was developed to synthesize key concepts, illustrate metrological procedures, present historical aspects of some of these constants, and suggest practical activities and examples of dimensional analysis.

Title: Métodos ativos de aprendizagem aplicados em aulas de física do ensino médio Author(s)/Inventor(s): Santos, William de Sant’Anna dos Advisor: Guimarães, Antônio Cândido de Camargo Abstract: We used two active learning methods, Just-in-Time Teaching (JiTT) and Peer Instruction (PI), in high school physics classes and from this experience produced an implementation guide for teachers. The active methods allow students to participate in the teaching-learning process in a collaborative way, being the protagonists of the knowledge construction. In this work we show that, based on the theory of Ausubel, Novak, Gowin and Vygotsky, the methods help in the process of achieving significant learning. Just-in-Time Teaching, in addition to assist students achieving a greater commitment with homework, allows the teacher to better decide which subjects should be worked out with greater attention. The teacher sends a reading material and a questionnaire that must be answered before the class and based on this feedback focuses the lecture on the points that have generated the most doubts. The method Peer Instruction consists basically in the application of conceptual tests that follow a dynamics in which students have no choice but to participate actively in the classroom activities. Students respond to classroom quizzes, question by question, discussing and trying to convince their classmates about the answers they thought correct. The methods are complementary and contribute to a truly meaningful learning. In order to verify the gain, we applied before and after school tests in two classes that developed the same content: one group subject to the active learning methods and another to the conventional method. We highlight the results of the experience that show that with the active methods students feel more confident and achieve better results in the evaluation. As a result of our work, our educational product is a guide for high school teacher meant to introduce and orientate them in the implementation of the active learning methods. Hopefully, we will facilitate the use of new and powerful tools, making the pedagogical process more dynamic and interesting for teachers and students, and the learning to be more effective.

Title: Desenvolvimento da biblioteca AcliveJS para simulações de fenômenos físicos Author(s)/Inventor(s): Nascimento, Wallace Robert da Silva Advisor: Ttira, Claudio Ccapa Abstract: Often the Teaching-Learning process about a certain physical phenomenon is compromised due to the students' difficulty of abstraction. In these cases, you can use media resources, whether in the form of videos or computer simulations. The use of these technologies seeks to facilitate the understanding of what is being studied. Based on this principle as the final product of the Master's dissertation, a javascript library, AcliveJS, was developed, whose purpose is to enable teachers to show or develop simulations of physical phenomena through internet browsers. The objective of this work is to present the AcliveJS simulation tool and to show the teacher how to develop a simulation through an example. Aim the results obtained from the application of the tool in the classroom and discuss the acceptance, advantages and disadvantages of using the tool. It is hoped that this work will be an invitation for the teacher to improve his professional practice and to incorporate more and more the use of new media resources in Physics Teaching, favoring the study and the reflection on the part of the students.
