The main objective is to develop laboratory practices that connect the theoretical content taught in the classroom with the professional reality and the demands of the job market of a technician. The research is based on the analysis of the curricular guidelines and the Pedagogical Course Projects (PPCs) of federal institutes in Goiás, both the IF Goiano and IFG (IF Goiás) evidencing the need for experiments that explore the professional scope by uniting syllabus contents seen in classrooms, the text discusses the relevance of safety in the laboratory, the use of PPE/EPCs and the correct management of the disposal of chemical waste. As a result, 11 practical experiments are proposed that cover industrial processes, oxidation-reduction reactions and various syntheses, providing a solid and integrated basis for the training of qualified professionals.

This study presents a literature review based on the analysis of 30 scientific studies on the biogenic synthesis of CuO NPs using plant extracts, fungi, and microorganisms as reducing and stabilizing agents. The findings demonstrate that the physicochemical properties of the nanomaterial are strongly influenced by experimental parameters such as pH, temperature, and the nature of the biological matrix. Characterization by UV–Vis spectroscopy, X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), and scanning/transmission electron microscopy (SEM/TEM) revealed a wide range of morphologies and crystallite sizes varying from 3 to 100 nm. In the agricultural context, CuO NPs exhibited multifunctional performance, acting as biostimulants that enhance seed germination and vegetative growth in crops such as tomato, lettuce, and wheat, particularly at low concentrations. In addition, they showed significant potential for phytosanitary control against major plant pathogens, including Fusarium oxysporum, as well as storage pests. However, the reviewed studies emphasize that their effects are strictly concentration-dependent, with high doses inducing phytotoxicity and oxidative stress. Overall, biogenic CuO NPs represent a promising innovation for sustainable agriculture. Nevertheless, the standardization of synthesis protocols and the assessment of their long-term environmental impacts remain essential challenges for their large-scale agricultural application.

The research shows that pedagogical practice goes beyond content transmission, encompassing ethical, social, and emotional dimensions that directly impact students’ holistic growth. Authors such as Freire (1996), Libâneo (1994; 2001), Tardif (2002), and Vygotsky (1998) emphasize that teaching is marked by complexity, requiring sensitivity, commitment, and the ability to foster meaningful learning. The analysis demonstrates that teachers’ actions contribute to stimulating motivation, engagement, and critical thinking, while also promoting values such as respect, solidarity, and social responsibility. The teacher is seen as an agent of transformation, capable of influencing not only academic performance but also citizenship and social awareness. It is concluded that the quality of teacher education is directly linked to the quality of education and to the positive impact on students’ academic and personal trajectories.
