This work presents a Didactic Sequence (SD) formulated from the dissertation titled "EXPLORING THE CONCEPTS OF BLACKBODY RADIATION FROM CLASSICAL TO MODERN PHYSICS WITH THE PEER INSTRUCTION METHODOLOGY," which investigated the effectiveness of the Peer Instruction (PI) methodology in teaching blackbody radiation concepts to students in the 11th stage of EJA (Youth and Adult Education). The main objective of the SD is to relate the types of electromagnetic radiation, especially thermal radiation, to the laws of Classical and Modern Physics that describe the radiation emitted and/or absorbed by a blackbody, using the PI methodology as a tool to promote active learning. The choice of PI is justified by its suitability to the EJA teaching structure, which combines synchronous classes (Mondays and Fridays) and face-to-face classes (Tuesdays, Wednesdays, and Thursdays). Asynchronous classes were used for the pre-class moment, where students had their first contact with the content. Face-to-face classes were used for the in-class moment, where content was reviewed based on students' difficulties, and to promote peer discussion. Following the implementation of the SD's preliminary version, the in-class moments were adjusted to better address the difficulties presented by the students. The SD consists of 4 classes, each lasting 55 minutes. The first 3 classes are structured around a pre-class moment and an in-class moment. However, these classes should have ideally been divided into 3 moments: pre-class, in-class, and post-class, where the objective is to consolidate learning through problem-solving. Nevertheless, considering the reality of the EJA students, the post-class moment was applied in the fourth class. The results from the SD's application indicated that students achieved at least 70% accuracy in problem solving situations, demonstrating the effectiveness of the PI methodology in teaching complex modern physics concepts within the EJA context.

The present research aims to investigate evidence of improved learning among Youth and Adult Education (EJA) students regarding the classical and modern descriptions of black-body radiation, resulting from the integration of the Peer Instruction (PI) methodology into the teaching-learning process. To achieve this objective, a qualitative study with an action research approach was conducted with 28 students in the 11th stage of the 2024 academic year of the Youth and Adult Education (EJA) program at the Antônio da Encarnação Filho State School, within the Amazonas State education network. Aligned with the theoretical framework of learning, the collected data were obtained through conceptual learning verification tests administered before, during, and after the lessons. The data analysis was performed using Content Analysis, with student responses as the unit of analysis. The data were categorized into Conceptual Understanding, Knowledge Application, and Opinion Change. The research concluded that the PI teaching methodology is effective in optimizing classroom time, promoting student engagement, and gradually improving their state of understanding and ability to apply the content. Consequently, students are able to progress from a partial understanding or skill after the pre-class phase to demonstrating comprehension or application skills during and after the lesson.
