Complex functions with Geogebra

Complex functions, generally feature some interesting peculiarities, seen as extensions real functions, complementing the study of real analysis. However, the visualization of some complex functions properties requires the simultaneous visualization of two-dimensional spaces. The multiple Windows of GeoGebra, combined with its ability of algebraic computation with complex numbers, allow the study of the functions defined from ℂ to ℂ through traditional techniques and by the use of Domain Colouring. Here, we will show how we can use GeoGebra for the study of complex functions, using several representations and creating tools which complement the tools already provided by the software. Our proposals designed for students of the first year of engineering and science courses can and should be used as an educational tool in collaborative learning environments. The main advantage in its use in individual terms is the promotion of the deductive reasoning (conjecture / proof). In performed the literature review few references were found involving this educational topic and by the use of a single software.

La matemática en la simulación con GeoGebra. Una experiencia con el movimiento en caída libre

Actualmente las experiencias de modelación y el uso de tecnologías digitales en las aulas de clase son temas de gran interés para los profesores, formadores e investigadores en Educación Matemática. Por un lado, la modelación matemática favorece el uso de la Matemática como un instrumento para el abordaje de situaciones y fenómenos del mundo. Por otro lado, integrar las tecnologías digitales (como simuladores, videojuegos, entre otros)en la enseñanza de las Matemáticas y las Ciencias, en particular de la Física, permite vincular los hechos e ideas asociadas a un fenómeno físico, entre sí y con marcos teóricos que los sustentan. Al fusionar la modelación y las tecnologías digitales a través de la simulación se obtienen entornos de aprendizaje que promueven el desarrollo de conocimiento y habilidades de pensamiento científico en los estudiantes. Sin embargo, la mayoría de las investigaciones en esta área están orientadas hacia una mayor comprensión de las formas de usar eficientemente estos simuladores en las clases de ciencias, dejando de lado al proceso de su elaboración como una verdadera oportunidad para aprender Matemática y otros saberes asociados. En este sentido, el presente trabajo describe la secuencia de pasos de construcción creada para elaborar un simulador del movimiento en caída libre con GeoGebra. Esto con el doble propósito de (i) develar la Matemática implícita en los procesos de construcción de simuladores con GeoGebra y (ii) motivar la creación de otros simuladores con un propósito similar al mencionado en este trabajo.

Identification and analysis of business and software services : A consolidated approach

Although the benefits of service orientation are prevalent in literature, a review, analysis, and evaluation of the 30 existing service analysis approaches presented in this paper have shown that a comprehensive approach to the identification and analysis of both business and supporting software services is missing. Based on this evaluation of existing approaches and additional sources, we close this gap by proposing an integrated, consolidated approach to business and software service analysis that combines and extends the strengths of the examined methodologies.

Business and software service lifecycle management

Although the service-oriented paradigm has been well established in the technical domain for quite some time now, service governance is still considered a research gap. To ensure adequate governance, there is a necessity to manage services as first-class assets throughout the lifecycle. Now that the concept of ser-vice-orientation is also increasingly applied on the business level to structure an organisation’s capabili-ties, the problem has become an even bigger chal-lenge. This paper presents a generic business and software service lifecycle and aligns it with the com-mon management layers in organisations. Using ser-vice analysis as an example, it moreover illustrates how activities in the service lifecycle may vary on lower levels of granularity depending on the focus on business or software services.
