A causal and correlational investigation was carried out of a non-experimental and transversal nature, in which 1,000 tourists who visited the city of Arequipa-Peru participated. These were intentionally selected to represent a specific sample. Two expert-validated surveys were used for data collection. The results indicated a moderate level of environmental education, with foreign professional women showing profound environmental knowledge. On the contrary, young national professionals demonstrated a profound commitment to the environment. These results underscore the significant link between environmental education and sustainable tourism. Nevertheless, a definitive conclusion was not reached about the study, as there could be other contributing factors.</p> 2024-02-27T16:16:55+00:00 Copyright (c) 2024 James Josmell Ojeda Portugal, Cecilia Alejandra Alarcon Vilca, Jeniffer Stephanie Diaz Santivanez, Diana Soledad Maquera Yucra, Raul Mauro Gonzales-Veliz Mathematical model in the optimization of the cost of heavy agricultural cargo transportation 2024-02-28T19:39:12+00:00 Juan Alberto Avalos Reyes Patricia Mercedes Cepeda Silva Paul Caceres <p><span class="OYPEnA text-decoration-none text-strikethrough-none">This work aimed to design a mathematical model to optimize the cost of heavy agricultural load transport using linear programming. The model was based on studying fixed and variable costs, including distance, cargo volume, arrival and departure times, lubricants, fuels, and other variables that influence transport pricing. The work had a quantitative approach, descriptive type, and its design of the non-experimental character with a cross-section. The methods were used, inductive, deductive, and systemic. For the collection of information, the survey was used as a technique and the questionnaire as an instrument, evidencing that most carriers do not know the calculation of the actual cost of transport, thus visualizing the need for a mathematical model in cost optimization, an achievement validated in the WINQSB program (Network Modeling Module).</span></p> 2024-02-27T16:46:34+00:00 Copyright (c) 2024 Juan Alberto Avalos Reyes, Patricia Mercedes Cepeda Silva, Paul Caceres Design of an educational strategy based on digital resources for the teaching of social sciences 2024-02-28T19:39:49+00:00 Cesar Camilo Zambrano Tomala Jisson Oswaldo Vega Intriago Marcos Fernando Pazmino Campuzano <p>This research proposes a pedagogical strategy incorporating digital tools for teaching Social Sciences.

These tailings are sometimes deposited in water effluents, close to mining production areas. Therefore, the purpose of the present investigation was to propose partial remediation of the exposed problem, with the use of zeolite, depositing this mineral on and under the mining tailings, carrying out 10 tests, with variation in the amount of zeolite, from 100 to 500 grams. The trials were subject to an action time of 30 days. The results obtained in the experimentation show that the test with 500 grams, placed at the bottom of the tailings, was the most efficient for the absorption of heavy metals, specifically with results of 43% in lead and 51% in arsenic, which benefits to the environment.</span></p> 2024-02-27T00:00:00+00:00 Copyright (c) 2024 Patricio Feijoo, Eduardo Luna Project Based Learning to promote the teaching of chemistry 2024-03-08T09:50:41+00:00 Karla Sofia Echeverria Giler Jean Carlos Perez Parra <p><span class="OYPEnA text-decoration-none text-strikethrough-none">El Aprendizaje Basado en Proyectos (ABP) se posiciona como una estrategia educativa valiosa que promueve el desarrollo de habilidades para la resolución de problemas prácticos. En este estudio se investigó la efectividad del ABP en comparación con el método de enseñanza tradicional en el contexto de la enseñanza de la química en la educación secundaria, específicamente en el abordaje del tema ácido-base.

The main results show that it is possible to obtain a pure and refined glycerol, in addition, it was observed that the parameters were within the regulations presented by several authors. It was also observed that the glycerol with better properties was obtained at 60 minutes at a temperature of 60ºC. In this way, it is possible to affirm that it is viable to use discarded oils as an alternative for their application in the elaboration of products that benefit the chemical, cosmetic, and pharmaceutical industries, as is the case of hydrogel, thus avoiding their incorporation into the environment.</span></p> 2024-03-08T17:14:50+00:00 Copyright (c) 2024 Steeven Jose Analuisa Mero, Luis Alberto Moreno Ponce, Segundo Alcides Garcia Muentes, Ramon Eudoro Cevallos Cedeno, Ariana Milena Garcia Bowen Use of GeoGebra for teaching quadratic equation 2024-04-03T11:33:23+00:00 Jaime Arias Mendez Fredy Yunior Rivadeneira Loor <p><span class="OYPEnA text-decoration-none text-strikethrough-none">The present study was carried out to massify the use of the GeoGebra program in high school mathematics teachers. A pretest was carried out, after the training an evaluation was used, and then a satisfaction survey with all the teachers, with the dependent variable being the learning of quadratic equations and the use of GeoGebra as an independent variable. The methodology consisted of using this software to motivate students in the teaching-learning process of mathematics. The main results show that the traditional teaching of mathematics can be complex for today's students, however, the use of technological tools such as GeoGebra is attractive to them, which causes motivation and consequently achieves more effective learning.</span></p> 2024-04-03T00:33:04+00:00 Copyright (c) 2024 Jaime Arias Mendez, Fredy Yunior Rivadeneira Loor Home experiments to promote the learning of mixtures in the subject of inorganic chemistry 2024-04-04T11:38:00+00:00 Paola Alexandra Zambrano Cevallos Kerly Leomar Toala-Vera <p><span class="OYPEnA text-decoration-none text-strikethrough-none">Chemistry is an empirical science and as such experimental work in the laboratory (or even at home) must be part of the teaching-learning process. Favorably, Chemistry is a science that allows many simple experiments to be carried out using easily accessible substances and materials. This paper aimed to implement home experiments to promote the learning of mixtures in inorganic chemistry subject. The applied methodology was descriptive and qualitative research. According to the results found, it is mentioned that experimentation goes beyond observation, because it offers the possibility of studying natural phenomena in greater depth, giving way to curiosity as an essential part of this practice. In conclusion, experimental activities in the laboratory are a fundamental part of the teaching and learning of Chemistry. However, many times its implementation can be limited by factors such as the lack of materials and instruments.</span></p> 2024-04-03T13:55:19+00:00 Copyright (c) 2024 Paola Alexandra Zambrano Cevallos, Kerly Leomar Toala-Vera Emancipatory education in the Ecuadorian context: a systematic literature review 2024-04-04T11:37:48+00:00 Alex Mauricio Alvarez Zurita Dilia Camacho Eduardo Simon Velasco Pullupaxi Carlos Alberto Andocilla Andrade <p><span class="OYPEnA text-decoration-none text-strikethrough-none">Emancipatory education is presented as an educational methodology that promotes the empowerment of students to achieve concrete learning goals.

Therefore, this research aimed to develop a didactic proposal of curricular adaptations for the learning of mathematical concepts in students with intellectual educational needs. In this context, a qualitative and<br>descriptive study took students with this condition and educational teachers as study individuals. The results obtained in the diagnosis externalized the importance of applying adaptations depending on the degree of complexity presented by each student. In this way, a proposal is presented that contributes to improving the teaching-learning process of young people with intellectual disabilities in different degrees and that allows them to strengthen fundamental mathematical concepts to include them in their daily activities and the environment that surrounds them.</p> 2024-04-26T14:39:31+00:00 Copyright (c) 2024 Wendy Fabiola Mendoza Sanchez
