<p>En los cursos de cinética química de licenciatura, se estudia la rapidez de las reacciones químicas, así como los efectos de temperatura en la rapidez de reacción, a través de ejercicios que utilizan métodos matemáticos como integración de ecuaciones de rapidez y funciones que se ajustan mediante regresión lineal. Con estos ejercicios, los alumnos desarrollan el tratamiento matemático de los datos sin lograr aprendizajes significativos. Es por ello, que surge la necesidad de crear ejercicios como “verdaderos problemas”, que tengan que ver con su vida cotidiana, esto es, aplicar el Aprendizaje Basado en Problemas (ABP). Se presenta el problema ¿Cuánto tiempo (en horas) se conserva la leche pasteurizada a temperatura ambiente?, a estudiantes de Fisicoquímica V (Cinética Química), de la carrera de Química de la FES Cuautitlán UNAM. A partir del cuestionamiento, surgieron una serie de preguntas, respuestas y acciones por parte de los estudiantes y del profesor. Con el modelo de primer orden, la ecuación de Arrhenius y el tratamiento matemático adecuado los estudiantes determinaron el número de horas en que se conserva la leche a temperatura ambiente. Los resultados mostraron que después de aplicar el ABP, los estudiantes comprendieron el efecto de la temperatura en la rapidez de la reacción. Esta estrategia, permitió estudiar el efecto de la temperatura en la rapidez de una reacción de una forma didáctica para lograr aprendizajes significativos, por lo que puede ser utilizado en los cursos de cinética química con el fin de incrementar el rendimiento académico.</p>
In developing countries, digital banking has been introduced and, although it has grown tremendously, it still coexists with traditional banking, with branch service. The objective of this study is to explore the elements in the quality perception of Generation Z that makes them prefer traditional banking to digital banking in the context of a developing country, Mexico. The study of quality perception is implemented through the application of the SERVQUAL model with 22 items. There were applied 394 online surveys to users of traditional or digital banking from generation Z. Qualitative content analysis is used to understand the customer's quality perception of traditional banking, in which the variables considered were: tangibility, reliability, responsiveness, assurance, and empathy, which were evaluated through a 7-point Likert-type satisfaction survey (1 = Completely disagree, 7 = Completely agree). In this study, it was identified that the responsiveness variable which considers the attitudinal aspects of the branch staff and communication with the staff in traditional banking services, is the one that has the greatest impact on generation Z consumers, regardless of their socioeconomic status, and therefore, explaining the preference for traditional banking services over digital ones. In addition, from favoring traditional services, Generation Z users have evolved from a product perspective to a service perspective, where the aspects of tangibility and reliability take the background, giving greater relevance to responsiveness, assurance, and empathy which are focused on the employeeconsumer internment. This study offers a strategic starting point that will facilitate the banking sector to plan the development of strategies that stimulate the migration of banking services to digital banking services.
Con el objetivo de investigar la percepción sobre las competencias de egreso de los estudiantes de la Licenciatura de Administración Hotelera del campus Playa del Carmen de la Universidad Autónoma del Estado de Quintana Roo, México, se recolectaron datos de egresados a través de una encuesta con escala tipo Likert. Y se encontró que los estudiantes se perciben con las competencias para: (1) dirigir un negocio en el sector hotelero, (2) diseñar sistemas y proceso de trabajo, (3) trabajar con actitud de servicio en el sector hotelero, (5) para fomentar una cultura de sustentabilidad, competitividad y calidad en la prestación de servicios y la administración hotelera y (6) adiestrar en situaciones reales de la administración hotelera. Pero que no se perciben con las competencias: (4) de liderazgo para gestionar y desarrollar al personal, (7) de respeto ético con la ciudadanía mundial, la humanidad y preservador de cultura, costumbre y valores de la región y las diferentes comunidades de México y (8) del dominio del idioma inglés. En conclusión, los estudiantes perciben que han desarrollado 5 de las 8 competencias del perfil de egreso de forma adecuada y por lo tanto es necesario reforzar las otras tres competencias en la licenciatura.
A problem-based online learning (PBe-L) teaching sequence was designed for calculating the shelf life (expiration date) of an on-site solution of refrigerated drug as part of activities of a Pharmaceutical Physical Chemistry course of Pharmacy major at FES Cuautitlán UNAM in Mexico. The teacher presents students the problem, a group collaborative activity is carried out to search for information in PBL cycles. Students are then shown a virtual experiment that includes experimental results. Another group collaborative activity is carried out for the search of information, for the procedural analysis of the results. Applying knowledge and understanding of the topics of chemical kinetics, temperature effect on the rate of chemical reactions and drug degradation reactions, etc., students solve the problem. Hake's factor was determined for the conceptual gain. A Likerttype satisfaction survey was conducted and compared to the results of a group that was applied to the PBL strategy in person. At the end of the sequence students achieved recognition, comprehension and application learnings and conceptual gain was high. Allowing an integration of its cognitive framework of kinetics topics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
