(2017) Encalada Serrano, Lisseth Lorena; Quito Vázquez, Erika Yessenia; Sánchez Karste, Francisco Javier
material and natural regeneration were taken. The assessment determined that the species has been overexploited and for this reason a conservation plan was proposed and it based on three main guidelines: research, conservation and education Molleturo is 36% of the area of the Cuenca canton, it haves a variety of climatic floors. Here, there are a diversity of plant and animal species and habitants have been benefiting from it, an example is the Palm of wax, people of Molleturo extract the leaflets and they elaborate handicrafts in Easter, in spite of that its commercialization is prohibited. The present investigation identifies areas potentially suitable for the growth of the Ceroxylon ventricosum species through of use of a potential distribution model called Maxent, it uses records of occurrence, and climate layers formed from meteorological information. The minimum training presence value was used to determine the cut-off threshold between presence/absence, the result was 0,39; the model was validated using Kappa of Cohen statistic, the result was 0,63. There are three zones of probability of presence in the obtained map, they correspond to high, medium and low, all equivalent 10,6% of the study area, these zones have the climatic and topographic characteristics suitable for the growth of the species. At the same time, an assessment of the population of the studied species was made; parameters such as elevation, diameter, stem height, density, soil use, canopy, dominance, physical state, reproductive.
Estrategias lúdicas en la enseñanza de números enteros en el octavo año de Educación General Básica

The current study implemented nine games focused on operations with whole numbers for the eighth-grade students of San Juan de Jerusalén School in the 2021-2022 academic year. An experimental group was selected to receive playful strategies while a control group did not. The validation process for the instruments, including pre-tests and post-tests, was conducted through expert judgment provided by teaching professionals who hold a fourth-level degree in Education from the University of Cuenca. The study began with the pretest and concluded with the posttest, and statistical analysis and hypothesis testing were conducted using the JAMOVI statistical package. The Shapiro-Wilk Test was utilized to determine the normality of the data, and the Levene Test was applied to verify the assumption of homogeneity of variances of the data obtained. The t-test for independent samples was utilized to make comparisons between the control and experimental group, while the t-test for paired samples was used to make comparisons between the same group but at different times (pre-test and post-test). Results indicated that the experimental group showed a significant increase in average, suggesting that playful strategies had a positive impact on the teaching of operations with integers.
