In this context, the present study aimed to investigate how inquiry-based experimental activities could contribute to students' participation, interpretation, and knowledge construction regarding the topic of Mixtures and Separation Methods in first-year high school classes. The proposal was based on the integration of theoretical, experimental, and problem-based activities, seeking to promote greater student engagement in Chemistry lessons. This study adopted a mixed-methods approach, combining qualitative and quantitative procedures through the use of diagnostic and final questionnaires, participant observation, and the implementation of a didactic sequence. The research was conducted with two first-year high school classes at a public state school located in Cezarina, Goiás, Brazil, during the morning shift. In both participating classes, students demonstrated active engagement during the inquiry-based experimental activities, particularly when they were able to manipulate materials, formulate hypotheses, discuss results, and relate chemical concepts to everyday situations. Evidence of increased student participation and interaction was also observed during group discussions, as well as improvements in the explanations presented throughout collaborative activities. Nevertheless, the study revealed that some conceptual difficulties persisted, particularly regarding questions that required higher levels of abstraction, interpretation of scientific language, and the articulation of different levels of chemical representation. The findings suggest that more carefully planned and systematically organized inquiry-based teaching proposals, supported by intentional teacher mediation, may contribute to greater student participation and a deeper understanding of chemical concepts.

Based on the understanding of the school library as a formative environment capable of integrating reading, writing, oral communication, and digital technologies, the study seeks to answer how the production of educational podcasts can redefine the role of the school library and contribute to the development of Creative Learning. The main objective is to analyze the role of the school library as an environment for creativity through the production of educational podcasts. The study adopts a qualitative, descriptive-interpretative approach, combining bibliographic research with empirical investigation conducted in a private school library located in the municipality of Pires do Rio, Goiás, Brazil. The participants were two middle school students and one Portuguese Language teacher. Data were collected through a semi-structured interview conducted in a podcast format and a satisfaction questionnaire administered to the participants. Data analysis was grounded in Pierre Bourdieu’s reflexive sociology, particularly the concepts of field, habitus, and capital, articulated with discussions on Creative Learning and school libraries. As an Educational Product, the podcast channel BibliocastNAescola was developed as a space for authorship, expression, and knowledge production. The findings indicate that the production of educational podcasts fostered student protagonism, expanded opportunities for oral expression and student authorship, strengthened the pedagogical mediation carried out by the school library, and promoted the integration of digital technologies with reading practices. It is concluded that the production of educational podcasts constitutes a pedagogical strategy capable of expanding learning experiences, strengthening student participation, and consolidating the school library as a space for creativity, pedagogical innovation, and collaborative knowledge construction in basic education.

In this context, this dissertation aimed to evaluate the potential of integrated soilborne pathogen management through the association of the nematicide fluopyram with the biological control agent Trichoderma harzianum ESALQ-1306 in tomato and melon crops. Field experiments were carried out in a randomized complete block design, with treatments involving single and combined inoculations of R. solani and Meloidogyne javanica in tomato, and of R. solani and Meloidogyne incognita in melon, in the presence or absence of fluopyram and T. harzianum. In tomato, the evaluated variables were root colonization frequency by T. harzianum, R. solani incidence, gall index, egg and second-stage juvenile populations, fresh root mass, and yield. In melon, in addition to root colonization and R. solani incidence, nematological indices, fresh root mass, and yield were assessed. In both crops, T. harzianum showed high root colonization frequency throughout the crop cycle, even in the presence of fluopyram, demonstrating compatibility between the chemical and biological strategies. Treatments containing fluopyram and/or T. harzianum reduced R. solani incidence and nematological indices compared with the infested controls, with more consistent responses observed for Meloidogyne spp. In tomato, the association between fluopyram and T. harzianum was effective in reducing gall index and final egg and juvenile populations, while maintaining yield, especially under coinoculation conditions. In melon, the treatments also promoted suppression of R. solani and Meloidogyne spp., with emphasis on the association between fluopyram and T. harzianum under coinoculation, which resulted in the highest yield. Overall, the results demonstrate that the combined use of fluopyram and T. harzianum ESALQ-1306 is a promising strategy to integrate the management of soilborne pathogens in vegetable crops, contributing to the reduction of fungal and nematode damage and supporting more sustainable and efficient production systems.

The storage sector plays a strategic role in agribusiness, requiring solutions that mitigate losses and optimize the conservation of agricultural assets. The central objective was to diagnose the technological maturity level of local units and develop a technical product capable of guiding the strategic modernization of these structures. Methodologically, the research is characterized as an applied case study using a mixed approach (quantitative and qualitative). Data collection was conducted through structured questionnaires sent to managers of storage units, and the treatment of qualitative data was based on Bardin's (2016) Content Analysis technique. The results indicate that the sector has a consolidated technological base for temperature and ventilation monitoring, processes considered highly effective by 100% of respondents. However, a significant gap was identified in the adoption of Industry 4.0 technologies, such as IoT and Artificial Intelligence, primarily due to high implementation costs and the need for a skilled workforce. Qualitative analysis revealed that technology is perceived not only as a physical preservation tool but also as a pillar of credibility, regulatory compliance, and access to financial credit. As a practical contribution, the Modular Strategic Guide for Technological Modernization was developed, offering a scalable roadmap for managers to implement innovations in a sustainable and financially viable manner. It is concluded that efficiency in storage management in Rio Verde depends on overcoming economic barriers through modular planning, ensuring the competitiveness and quality of grain in the global market.
