Determinación experimental de los índices de refracción complejos de metales
(2021) Lata Reino, Richard Eduardo; Rojas Rojas, Marco Alejandro; Guachún Lucero, Freddy Patricio; Rojas Rojas, Irma Alicia
This work describes the process followed to determine the complex refractive indices of metals, by means of a simple experimental process, so that it can be carried out in a university optics laboratory. This is as an alternative method to traditional processes that involve sophisticated and high-cost materials that are often not counted in a conventional laboratory. For the process, a gold foil and two sources of different wavelengths were used, a sodium lamp and a Helium-Neon laser. The experimental results agree acceptably with the data found in specialized books on optics. Among the conclusions, it stands out: It has been shown that the spectrogoniometer is a very useful device to be able to carry out experiments on optics in which angles play a relevant role. Its handling and finetuning has in itself been a good kind of refresher on optical concepts.
El software GeoGebra como recurso para la enseñanza de la Integral definida: una propuesta didáctica.
(Alonso María Arce de la CCE. Núcleo del Cañar, 2020) Rojas Rojas, Irma Alicia; Guachún Lucero, Freddy Patricio; Rojas Rojas, Marco Alejandro
This work shows the results obtained from a didactic experience with the students of Mathematics of the third year of the General Unified Baccalaureate of the President Jaime Roldos Educational Unit of the canton La Troncal-Ecuador, during the 2019-2020 school year. In this experience, the GeoGebra software was used as a resource for teaching the subject of definite integrals. The methodology applied during the research is quantitative with a descriptive approach, the research variables are the motivation that was measured with a perception survey and the knowledge acquired that was measured through a knowledge test. The main conclusions indicate that using the GeoGebra software favors the understanding of the concepts of the definite integral in students, since it allows them to better visualize the process carried out, which increases the motivation to learn this complex subject of mathematics. These results show that the GeoGebra Software is a useful tool for teaching especially in these moments in which, due to the pandemic caused by Covid, virtual education prevails in all educational institutions in the country.
Guía didáctica de rúbricas de evaluación para el bloque uno de números y funciones, dirigida a docentes de matemáticas de segundo año de bachillerato
(2016) Rojas Rojas, Irma Alicia; Tapia Malla, Natalia Raquel; Lliguaipuma Aguirre, Mónica del Carmen
El presente trabajo titulado “Guía Didáctica de Rúbricas de Evaluación para el Bloque Uno de Números y Funciones, dirigida a docentes de matemática de Segundo Año de Bachillerato” ha sido diseñado con la intención de fortalecer el proceso de evaluación a través de la utilización de un nuevo instrumento, la rúbrica; con el objetivo de facilitarla tarea evaluadora del docente. En el primer capítulo, se da a conocer de manera general los cambios que ha sufrido la educación en los últimos años, la necesidad de conocer y relacionar las corrientes pedagógicas innovadoras como el constructivismo y la teoría del aprendizaje significativo con la evaluación del proceso educativo, la didáctica en el ámbito de la matemática, y la implementación de guías didácticas y rúbricas como instrumentos de apoyo para el docente. En el segundo capítulo se busca dar sustento a la propuesta mediante la aplicación de una encuesta, en la cual se evidenciala falta de instrumentos de evaluación que rompan el estigma de la utilización únicamente de pruebas en este proceso, además la factibilidad del uso de una guía didáctica de rúbricas para la matemática. Finalmente, en el tercer capítulo se presentan20 modelos de rúbricas holísticas y analíticas desarrolladas por cada actividad, referidas al Bloque Uno de “Números y Funciones” en base a las Destrezas con Criterio de Desempeño de acuerdo a lo que se establece en el Currículo del sistema educativo ecuatoriano. The following working paper entitled as “Teaching Guide about Evaluation Rubrics in Block One ‘Numbers and Functions’ addressed to Mathematics Teachers of Second Year of BGU” has been designed with a view to strengthening the evaluation process through the use of a new instrument, the rubrics, in order to facilitate the evaluation task for teachers. In the first chapter, it is reported, in a general manner, the changes that have undergone education in recent years; the need of knowing and relating the innovative educational tendencies such as Constructivism and Meaningful Learning Theory with the evaluation in the educational process; Didactics in the field of Mathematics; and the implementation of teaching guides and rubrics as supporting tools for teachers. In the second chapter, it intends to provide support to the proposal by implementing a survey, in which the lack of assessment tools to break the stigma of using only one test in the teaching and learning process is evident. Moreover, it presents the feasibility of developing a teaching guide about rubrics for mathematics. Finally, in the third chapter, it introduces twenty holistic and analytic rubric templates developed for each activity referred to Block One “Numbers and Functions,” based on the Skills with Performance Criteria as set out by the educational system in the Ecuadorian National Curriculum.
