En el presente artículo proponemos una herramienta numérica en forma de laboratorio virtual, sencilla e intuitiva, desarrollada en el entorno del software Mathematica que permite resolver interactivamente las ecuaciones de la Mecánica del Vuelo simétrico de un avión y obtener resultados directamente relacionados con el diseño estructural. Se muestra el funcionamiento del modelo con algunos ejemplos.","PeriodicalId":18645,"journal":{"name":"Modelling in Science Education and Learning","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78969040","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Esta experiencia tiene como objetivo incorporar las Tecnologias de Informacion y Comunicacion (TICs) en el proceso de ensenanza y aprendizaje de la ingenieria. El contenido del programa se distribuye en tres modulos diferentes: “Ensayo de compactacion”, “Ensayo de consolidacion” y “Ensayo de corte directo”. Usando graficos vectoriales, tablas, figuras ilustrativas, animaciones, ecuaciones, botones de ayuda y correccion inmediata de errores, el software aclara la relacion entre conceptos teoricos y resultados practicos de laboratorio, instruye a los estudiantes en los momentos de duda, atrae su interes y motiva ellos para lograr la interpretacion completa de datos. Con base en los resultados de un cuestionario de evaluacion, se observo que la mayoria de los estudiantes quedaron satisfechos con los contenidos y las funcionalidades del programa. La herramienta desarrollada puede ser una inspiracion para la creacion de nuevos programas educativos que mejoren la calidad de la educacion en diferentes areas de la ingenieria. EnglishThis work aims to implement and evaluate an interactive educational software that helps Civil Engineering students to perform and analyze the calculations related to different Soil Mechanics laboratory tests. This experience consists of an attempt to incorporate information and communication technologies (ICTs) into the engineering teaching-learning process. The content of the program is distributed into three different modules: “Compaction test”, “Consolidation test”, and “Direct shear test”. Using vector graphics, tables, illustrative figures, animations, equations, tip buttons, and immediate correction of mistakes, the software clarifies the relationship between theoretical concepts and practical laboratory results, instructs the students in the moments of doubt, attracts their interest, and motivates them to achieve the complete data interpretation. Based on the results of an applied evaluation questionnaire, it was observed that most of the students were satisfied with the contents and functionalities of the program. The developed tool can be an inspiration for the creation of new educational software that improve the quality of education in different engineering areas.","PeriodicalId":18645,"journal":{"name":"Modelling in Science Education and Learning","volume":"103 1","pages":"43-54"},"PeriodicalIF":0.0,"publicationDate":"2018-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79411607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

En un primer experimento, destinado a estudiantes de Secundaria y niveles superiores, las medidas de la presion obtenidos a diferentes profundidades permiten realizar un ajuste lineal, comprobando asi la validez de la Ley de Stevin.  Ademas, a partir de dicha ley y de los parametros del ajuste se puede determinar la densidad del agua. Los valores obtenidos indirectamente por este procedimiento difieren entre un 2% y un 4% del resultado de dividir entre si la masa y el volumen de una muestra. En un segundo experimento, mas enfocado a estudiantes de primeros cursos universitarios de asignaturas de Fisica, el telefono movil sumergido oscila suspendido de un muelle. Las medidas del sensor de presion permiten, mediante la Ley de Stevin, obtener la serie temporal de la presion en la correspondiente oscilacion amortiguada, cuyos parametros se determinan mediante un ajuste no lineal. La comparacion de la pulsacion libre obtenida a partir de estos valores difiere en un1,5% respecto del obtenido a partir de la medicion directa del periodo fuera del agua.  En ambos casos, los resultados obtenidos indican la efectividad del metodo utilizado en contextos docentes.","PeriodicalId":18645,"journal":{"name":"Modelling in Science Education and Learning","volume":"7 1","pages":"15-24"},"PeriodicalIF":0.0,"publicationDate":"2018-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76272006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Economics, business and finance are mainly based on data and dealing with data requires specific skills and techniques such as computer programming in order to get full potential of most quantitative models. In this paper, we propose a coding oriented learning method based on Python Notebooks which is specifically designed for students of degrees in economics, business and finance. We follow a learning-by-doing strategy that encourages students to implement economic models as a suitable way to improve the understanding of fundamental concepts. As an illustrative example, we also describe a case study in which Python Notebooks are the key tool to teach cash management in a Master in Business Administration program. Since students of today are the decision-makers of tomorrow, a further advantage of the use of a programming language as a teaching tool is the possibility to connect theory to practice by enabling students to implement their own decision support tools.","PeriodicalId":18645,"journal":{"name":"Modelling in Science Education and Learning","volume":"4 1","pages":"55-64"},"PeriodicalIF":0.0,"publicationDate":"2018-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87637936","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present work illustrates how, from the simplest equations of hydrodynamics, it is possible to contribute to this end. Bernoulli and continuity equations are included in Physics syllabi of secondary and university levels, and can be seen as a linking between general and professional education. By means of the proposed project, students are taken through general stages which are usually present in any engineering project or research work based on modeling and simulation. such as the formulation of the problem, the statement of the Physics model, a computational simulation and the comparison between theory and experiments. This kind of project allows for the development of modeling skills and also to some other typical skills of the scientist's and engineer's profiles nowadays, such as  fitting and graphing analysis. It is common to see that secondary and  first year university courses do not contribute much to the formation of modeling skills, instead they rather contribute to particular skills from the perspective of the different subjects. On the other hand, students are usually more motivated for the modeling of real world situations than for idealized ones.","PeriodicalId":18645,"journal":{"name":"Modelling in Science Education and Learning","volume":"2013 1","pages":"211-222"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88095613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
