Computer Animation to teach interpolation
2019
<div data-canvas-width="460.953206963072">Aunque las asignaturas de matemáticas son un tema básico en los estudios de una ingeniería, a menudo son considerados por los estudiantes como una asignatura difícil. En este trabajo presentamos una experiencia de aprendizaje basada en la animación por ordenador mediante el uso de la modelización matemática. Nuestro objetivo es proporcionar a los estudiantes un contexto que motive el estudio de la interpolación de funciones. Presentamos un planteamiento del problema que se pretende resolver mediante</div><div data-canvas-width="460.9542195018301">el Ciclo de Modelización.

Bot or not? a case study on bot recognition from web session logs
2018
This work reports on a study of web usage logs to verify whether it is possible to achieve good recognition rates in the task of distinguishing between human users and automated bots using computational intelligence techniques. Two problem statements are given, offline (for completed sessions) and on-line (for sequences of individual HTTP requests). The former is solved with several standard computational intelligence tools. For the second, a learning version of Wald’s sequential probability ratio test is used.
Obstacles modelling reality: Two exploratory studies on physics defined and undefined problems
2014
For some researchers, and perhaps for many teachers, problem-solving is strongly related to thinking (Mayer, 1983). Several reports highlight the importance of developing suitable skills to solve complex, ill-defined and boundless real-life problems in educated people (NSF Standards, U.S. Department of Labour, ABET engineering accreditation organization, and American Institute of Physics, mentioned in Etkina & Van Heuvelen, 2007; Bureau of Labour Statistics, U.S. Department of Labour, 2014; Competency Model Clearinghouse, 2012). Problem-solving is virtually the core of the professional activity of a physicist (Etkina, Van Heuvelen, White-Brahmia, Brookes, Gentile, Murthy, Rosengrant & Warre…
Cyber Security Strategy Implementation Architecture in a Value System
2018
In this chapter, we introduce an approach toward enhancing the quality of strategy implementation. As a framework, we use cybersecurity strategy implementation planning and execution. Justification for this work is the observed need to be able to perform strategy readjustment processes quickly and in an agile way, when needed. This requires processes and practices that are simple enough and executable with small resources in a relatively short timeframe. The problem statement can be formulated as follows: “We need to determine an utterly simplified, noncomplicated model to help us to tackle the complex problem of implementing a cybersecurity strategy of adequate efficiency in a changing ope…
The Principles of universal design for learning implementation in design study process
2015
Problem Statement: Starting their studies students have different level of perception and understanding. There is a need for an instructional framework that would allow educational programming, inclusive for all students.Research Questions: What is diversity of students learning strategies how can be facilitated students perception ability, expression and cooperation skills?Purpose of the Study: Objective of the current study is to investigate pedagogical possibilities to promote design students perception abilities and reasoning skills using in learning process principles of Universal Design for Learning (UDL) in context of student’s diversity.Research Methods: In start up phase students w…
What seems to be the problem?—A study of connections between national contexts and regional e-health strategies
2015
Abstract Motivation Different e-health strategies may produce different long-term results, so it is of general interest to look into strategies behind e-health approaches, and what factors that influence strategy-formation. Problem statement Previous studies into process improvements in the e-health area has suggested that approaches and strategies are very dependent on national contexts. This study explores this issue, by sampling two national regions in Europe, the St. Gallen region and canton in Switzerland, and the Agder region comprised of the two Agder-counties, in Norway. The research questions revolve around the extent to which the context influences e-health innovation in two diffe…
Missing Curious Fraction Problems
2018
In this paper we present a study of one of the best-known types of descriptive word fraction problems. These problems have disappeared from today’s textbooks but are hugely important for developing arithmetic thinking. The aim of this paper is to examine the historical solution methods for these problems and discuss the analytical readings suggested by the authors. On the basis of this analysis we have conducted a preliminary study of the performance of 35 Spanish students who are highly trained in mathematics. Our results show that these students have a preference for algebraic reasoning, are reluctant to use arithmetic methods, and have reading comprehension difficulties that are reflecte…
