description: This article offers an overview of the challenges and opportunities that artificial intelligence (AI) offers in continuing teacher training, highlighting its transformative potential in diverse contexts and its structural limitations. It explores how AI personalizes learning through adaptive systems that identify individual needs and suggests a national platform that optimizes resources and promotes pedagogical innovation. It addresses challenges that create a digital divide through online solutions and workshops that support equity, especially in rural areas, given the shortcomings teachers face in this context. It reveals the need for new teaching competencies that integrate practical skills with tools such as chat and ethical reflection. Through modules and workshops piloted at universities, suggestions are offered to the national AI-based network to strengthen university-society relations and promote the exchange of experiences between educators from diverse regions, with transparent, equitable, and autonomous ethical implications, in line with Cuban humanistic values. Strategies of local practices and interdisciplinary collaboration with equitable and ethical approaches are resumed to continuing teacher training, fostering socialization, innovation, the exchange of experiences, and the development of human capital from the university level.

Exploring capabilities, uses and perspectives of pyroligneous acid in agriculture
type: item
description: Pyroligneous acid, obtained from the pyrolysis of organic matter, has emerged as a promising alternative in sustainable agriculture due to its properties and ability to improve soil quality. The evidence collected indicates that pyroligneous acid exhibits antimicrobial activity in vitro and in vivo against a range of plant pathogens, including fungi, bacteria and nematodes, showing significant potential for the biocontrol of diseases in various crops. Its use as a herbicide has shown positive results in inhibiting the growth of weeds without negatively affecting the desired crops. Furthermore, several studies demonstrate that pyroligneous acid induces systemic defense responses in plants, increasing their resistance to biotic stresses. Regarding direct uses in growth, it was observed that it can promote root growth, nutrient absorption and tolerance to abiotic stress, such as drought and salinity, improving crop performance in less than optimal conditions. Despite these promising findings, the review also identifies significant gaps in the research. Most studies have been carried out on a laboratory or greenhouse scale, making it necessary to validate these effects in large-scale field trials in different agroecological conditions (need for multicenter studies). Likewise, a greater understanding of the molecular mechanisms underlying the interactions of said compound with plants and soil microorganisms is required.

Identification of multi-risk disasters in the community
type: item
description: This research is part of the project "Capacities' Formation for Student Leadership in Addressing the Effects of Climate Change from Schools to Coastal Communities in Granma", responding to the need to develop a system of actions aimed at reducing vulnerabilities to multi-hazard disasters among students and communities, incorporating Environmental Education for Sustainable Development. The study suggests better preparation for students, families, and communities in disaster risk reduction and resilience to climate change, which should begin in schools and extend to ommunities. This approach will help them acquire knowledge on how to contribute to Environmental Education and Disaster Education while preserving the environment. Thus, the research aims to develop a multisectoral action system to enhance students' and communities' understanding of multi-hazard disasters. The applied theoretical, empirical, and statistical research methods allowed for the validation of the results.

The divisibility rule in the teaching of Mathematics
type: item
description: The divisibility criteria in the teaching of Mathematics play an important role in the study of arithmetic in Primary Education, these are used to simplify fractions, to investigate whether a given number is prime or not, among other contents. From the study carried out by different authors where their treatment is exposed in deferent literatures, it can be seen using the concept of numerical congruence, however, the treatment of textbooks that allow students to appropriate this content is not explained in the textbooks, which is the objective of this work. A study of the divisibility relationship in the whole numbers is carried out; where said relationship is defined and exemplified, it is necessary properties are stated or demonstrated to obtain or demonstrate a considerable amount of divisibility criteria, some of these are exemplified and one of its applications to the resolution of exercises with text directed to this end is illustrated. This work was introduced in the corresponding content of the Mathematics I study program with a population of three groups and a sample of group of the Bachelor of Primary Education.
