The inclusive mathematics class for visually impaired sixth graders
The research arises from the inadequacies detected, modeling the mathematics class for sixth grade students with visual impairment as an inclusive practice in Special Education. Mathematics is one of the subjects that generates more doubts to the teachers when they have a blind student in class, since the learning of the contents has in many occasions a great visual component and the use of abstract concepts raise doubts when explaining and reinforcing the activities; so, it is a challenge for the teachers the attention to the diversity. From the application of theoretical and empirical methods, which guaranteed obtaining the information and processing for analysis, allowed the development of the proposal of an inclusive Mathematics class for sixth grade students with visual impairment in Special Education, which allows the teacher to perform differentiated work achieving true equality for the attention to diversity within the Educational Institutions.

Exploring capabilities, uses and perspectives of pyroligneous acid in agriculture
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
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
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.
