The research adopted a qualitative approach with an exploratory and descriptive design. Data collection involved both preintervention discursive and post-intervention objective conceptual tests, as well as observation records. Data were analyzed qualitatively using the content analysis method applied to the students' responses. The DS was implemented with 25 students from a public school in Manaus, Amazonas. The results indicated that the pedagogical intervention was effective. In the pre-test, the majority of students did not demonstrate robust evidence of meaningful learning on the topics. However, after the DS was implemented, a significant learning gain was observed across all topics, as measured by Hake's normalized gain. Specifically, for Wien's Law, the normalized Hake gain was 0.79, which is considered high, indicating that students understood the relationship between wavelength and temperature. For the concepts of object color (absorption and reflection), the gain was 0.94, also classified as high, showing that students grasped the process of color formation. Regarding the atomic models, the gains were 0.47 for Dalton, 0.67 for Thomson, 0.46 for Rutherford, and 0.68 for Bohr. Although these gains are considered medium, they still represent a significant improvement compared to traditional methods. Finally, for spectral lines, the gain was 0.78, a high gain. The overall normalized gain of the DS was 0.67, which indicates that the teaching methodology employed fostered active student participation and the development of conceptual understanding, thus characterizing meaningful learning.

The research was developed at the Professor Jorge Karam Neto State School, in the city of Manaus-AM, seeking to understand how the integration between theory and practice, through the construction and programming of robots, can favor the learning of the fundamental concepts of dynamics. The development of the work was structured in four phases: analysis, elaboration, implementation and evaluation. In the analysis phase, diagnostic questionnaires were applied to identify the students' prior knowledge and their learning needs in relation to Newton's laws. Based on these data, a teaching-learning sequence based on Project-Based Learning was developed, in which the students, organized in groups, planned, assembled and programmed robots capable of participating in practical challenges, such as tug-of-war and sumo wrestling competitions. During implementation, students were challenged to apply concepts of force, mass, acceleration, and action and reaction to optimize the performance of prototypes, integrating physical knowledge into the assembly and programming processes of devices. Assessment was carried out continuously, using formative assessment instruments, using specific rubrics that allowed monitoring the progress of students in criteria such as understanding of concepts, teamwork, application of data, and reflection on their own learning process. In addition to the formative assessment, a final assessment was conducted on students' perceptions of the activities performed. The results demonstrated that the use of educational robotics, combined with the Project-Based Learning methodology, provided a more dynamic, collaborative, and meaningful learning environment, contributing to a better understanding of physical concepts and the development of essential skills, such as critical thinking, logical reasoning, and problem-solving. It is concluded that the adopted approach not only promoted the strengthening of Physics knowledge, but also encouraged autonomy, protagonism and student engagement, demonstrating that active methodologies integrated with technology constitute an effective strategy for improving Physics teaching, especially in high school.

The goal is to examine the potential of using the Pictoblox platform as a supporting tool in high school physics education. Given the challenges faced in the learning process of this subject, often characterized by abstract and decontextualized approaches, this study seeks to assess how the introduction of a block-based programming language, integrated with sensors and electronic components, can contribute to building physics knowledge in a more interactive, experimental, and meaningful way. Thinking about overcoming such obstacles and motivating high school students to study physics, we thought of using the software PictoBblox, a tool based on SCRATCH, which allows the development of programming in blocks, and also allows connection to boards (microcontrollers) Arduino. The use of the Arduino board will be of great importance in this research, as this is the time when students will need to exercise their knowledge about circuits and, by building and handling variations of these circuits, it will be possible to achieve significant learning on the topic covered. The option to promote a didactic sequence using this software to teach electrical circuits is based on the use of technology to make physics more attractive and understandable to students, making them not only understand the content, but also recognize the importance of learning it.

In addition to these and other curricular changes, the base also brought another set of pedagogical proposals to be innovative by teachers in the classroom. One of these changes involves technological transformations. We therefore observe that the use of Digital Information and Communication Technologies (DICT’s) in education has become an emerging theme. Given this macro scenario, this led us to ask the following question: Is it possible to understand the concepts necessary for building simple electrical circuits using computer simulations as a tool, relating them to real electrical circuits, through a didactic sequence implemented from the perspective of Raymond Duval's Theory of Semiotic Representation Registers? This study aimed to answer this question by developing and applying a structured teaching sequence based on the progression of semiotic registers applied to the construction of simple electrical circuits using the NI Multisim software environment. In this study, we employed a collaborative teaching strategy based on the use of different registers of semiotic representations, mobilizing them and verifying whether the gaps between registers of representations of the same object influenced a better understanding of essential concepts for the construction of these circuits. We highlighted the importance of coordinating the different types of languages present in the teaching of Physics, be it symbolic, algebraic, oral or written, demonstrating the relationships involved and their emotions. This led us to conclude that the teaching of Physics, be it through expository classes, experiments, computational models, active methodologies, etc., should be developed based on the evolution of these registers.
