Title: Materiais Magnéticos: como são abordados em alguns livros didáticos voltados ao Ensino Médio Abstract: The magnetic properties of matter is a topic often neglected and overly simplified in high school Physics textbooks. This study conducts a survey of 15 textbooks provided by PNLD 2018 and PNLD 2026. The methodology is grounded in Yves Chevallard’s Anthropological Theory of the Didactic (ATD), with its analytical framework reinforced by Bittar’s proposal, which segments content into course sections and proposed activities. Additionally, Bardin’s Content Analysis is employed to categorize and codify the conceptual depth levels related to magnetic materials (ferromagnetic, paramagnetic and diamagnetic) into three tiers: Superficial, Intermediate and In-depth. Results reveal that 53,3% (8 books) adopt a Superficial approach, 40% (6 books) an Intermediate one and only 6,7% (1 book) an In-depth treatment. Furthermore, just 46,7% (7 books) include specific exercises or activities on the topic. These finding highlight a significant theoretical and methodological gap, undermining students proper conceptual understanding of magnetic materials.

Title: O RPG como uma ferramenta lúdica para o ensino de Física Abstract: This work aims to present the use of Role-Playing Game (RPG) as an active methodological practice, exploring playfulness to foster the understanding of Newton’s three Laws. The proposal is based on the idea that students, guided by challenges and mediated by the teacher, can build knowledge in a meaningful way. To this end, the concept of RPG and its gameplay dynamics are discussed, as well as its educational feasibility in light of the Base Nacional Comum Curricular (BNCC), through a comparison between the competencies outlined in the document and the benefits highlighted by authors who have investigated its application in education. The study also presents a logical-historical approach to Newton’s Laws, discussing the ideas and arguments of scholars of the time and their relation to current formalization. As a result of these analyses, a ludic game entitled “A Sinfonia do Saber” is proposed, offering students a logical pathway similar to the one described and contributing to their understanding of Newton’s Laws.

Title: Kit didático com blendas poliméricas: explorando novas possibilidades no ensino de fotoluminescência e óptica Abstract: This work presents the development of a teaching kit for teaching photoluminescence and optics in high school. It uses conjugated polymers, materials known for their semiconductor and photoluminescent properties, with great potential for technological applications. During the development of the kit, polymer blends were prepared in solid and liquid states. The blends were produced by mixing a bicomponent polymer resin with the photoluminescent polymer MEH-PPV (poly[2-methoxy-5-(2'-ethylhexyloxy)-1,4-phenylenvinylene]). Photoluminescent blends were also prepared using polyfluorenes. To prepare the photoluminescent polymer solutions, mixtures were made with acrylic varnish and the same photoluminescent polymers used in the preparation of the solid and liquid blends. The kit includes these blends and optical lenses and is accompanied by lesson plans that guide their application in the classroom, promoting a practical approach that encourages observation, questioning, and scientific experimentation by students. To evaluate the material's applicability, the kit was presented to high school students at a public school in Uberlândia, with the aim of sparking their interest in scientific topics. During the demonstration, concepts such as the visible light spectrum and the functioning of photoluminescent polymers were covered. The students' active participation highlighted the kit's potential as a teaching resource for experimental science education.

Title: Desenvolvendo competências em Física por meio da programação: Um estudo sobre o uso do Scratch na educação Abstract: This text presents the implementation and evaluation of a didactic sequence for teaching Physics, using the Scratch platform, which is a block programming language, as a pedagogical tool. The main objective is to explore the contributions of Scratch, which is classified as a Digital Information and Communication Technology, in learning physical concepts, as a way of promoting active learning. The didactic sequence was applied in two in-person meetings, carrying out proposed activities and collecting student opinions. The results obtained demonstrated that the use of the Scratch tool promotes active and meaningful learning of physical concepts by students.
