Design, implementation and evaluation of a virtual laboratory for Computer Engineering Education

Broad consensus has been reached within the Education and Cognitive Psychology research communities on the need to center the learning process on experimentation and concrete application of knowledge, rather than on a bare transfer of notions. Several advantages arise from this educational approach, ranging from the reinforce of students learning, to the increased opportunity for a student to gain greater insight into the studied topics, up to the possibility for learners to acquire practical skills and long-lasting proficiency. This is especially true in Engineering education, where integrating conceptual knowledge and practical skills assumes a strategic importance. In this scenario, learners are called to play a primary role. They are actively involved in the construction of their own knowledge, instead of passively receiving it. As a result, traditional, teacher-centered learning environments should be replaced by novel learner-centered solutions. Information and Communication Technologies enable the development of innovative solutions that provide suitable answers to the need for the availability of experimentation supports in educational context. Virtual Laboratories, Adaptive Web-Based Educational Systems and Computer-Supported Collaborative Learning environments can significantly foster different learner-centered instructional strategies, offering the opportunity to enhance personalization, individualization and cooperation. More specifically, they allow students to explore different kinds of materials, to access and compare several information sources, to face real or realistic problems and to work on authentic and multi-facet case studies. In addition, they encourage cooperation among peers and provide support through coached and scaffolded activities aimed at fostering reflection and meta-cognitive reasoning. This dissertation will guide readers within this research field, presenting both the theoretical and applicative results of a research aimed at designing an open, flexible, learner-centered virtual lab for supporting students in learning Information Security.

Next generation e-learning platform: virtual laboratory simulations

Bioscience subjects require a significant amount of training in laboratory techniques to produce highly skilled science graduates. Many techniques which are currently used in diagnostic, research and industrial laboratories require expensive equipment for single users; examples of which include next generation sequencing, quantitative PCR, mass spectrometry and other analytical techniques. The cost of the machines, reagents and limited access frequently preclude undergraduate students from using such cutting edge techniques. In addition to cost and availability, the time taken for analytical runs on equipment such as High Performance Liquid Chromatography (HPLC) does not necessarily fit with the limitations of timetabling. Understanding the theory underlying these techniques without the accompanying practical classes can be unexciting for students. One alternative from wet laboratory provision is to use virtual simulations of such practical which enable students to see the machines and interact with them to generate data. The Faculty of Science and Technology at the University of Westminster has provided all second and third year undergraduate students with iPads so that these students all have access to a mobile device to assist with learning. We have purchased licences from Labster to access a range of virtual laboratory simulations. These virtual laboratories are fully equipped and require student responses to multiple answer questions in order to progress through the experiment. In a pilot study to look at the feasibility of the Labster virtual laboratory simulations with the iPad devices; second year Biological Science students (n=36) worked through the Labster HPLC simulation on iPads. The virtual HPLC simulation enabled students to optimise the conditions for the separation of drugs. Answers to Multiple choice questions were necessary to progress through the simulation, these focussed on the underlying principles of the HPLC technique. Following the virtual laboratory simulation students went to a real HPLC in the analytical suite in order to separate of asprin, caffeine and paracetamol. In a survey 100% of students (n=36) in this cohort agreed that the Labster virtual simulation had helped them to understand HPLC. In free text responses one student commented that "The terminology is very clear and I enjoyed using Labster very much”. One member of staff commented that “there was a very good knowledge interaction with the virtual practical”.

Understanding and representing atmospheric convection across scales: recommendations from the meeting held at Dartington Hall, Devon, UK, 28–30 January 2013

As weather and climate models move toward higher resolution, there is growing excitement about potential future improvements in the understanding and prediction of atmospheric convection and its interaction with larger-scale phenomena. A meeting in January 2013 in Dartington, Devon was convened to address the best way to maximise these improvements, specifically in a UK context but with international relevance. Specific recommendations included increased convective-scale observations, high-resolution virtual laboratories, and a system of parameterization test beds with a range of complexities. The main recommendation was to facilitate the development of physically based convective parameterizations that are scale-aware, non-local, non-equilibrium, and stochastic.

Special Issue: Interactive Educational Media for the Neural and Cognitive Sciences

Understanding the functioning of brains is an extremely challenging endeavour - both for researches as well as for students. Interactive media and tools, like simulations, databases and visualizations or virtual laboratories proved to be not only indispensable in research but also in education to help understanding brain function. Accordingly, a wide range of such media and tools are now available and it is getting increasingly difficult to see an overall picture. Written by researchers, tool developers and experienced academic teachers, this special issue of Brains, Minds & Media covers a broad range of interactive research media and tools with a strong emphasis on their use in neural and cognitive sciences education. The focus lies not only on the tools themselves, but also on the question of how research tools can significantly enhance learning and teaching and how a curricular integration can be achieved. This collection gives a comprehensive overview of existing tools and their usage as well as the underlying educational ideas and thus provides an orientation guide not only for teaching researchers but also for interested teachers and students.

Desarrollo de una aplicación software para laboratorios remotos

Las prácticas en laboratorios forman una parte muy importante de la formación en todos los programas docentes. A pesar de esta importancia, la creación de un laboratorio no es una tarea fácil, ya que el hecho de equipar un laboratorio puede suponer un gran gasto económico, tanto inicial como posterior. Como solución, surge la educación a distancia, y en concreto los laboratorios virtuales, es decir, simulaciones de un laboratorio real utilizando modelos matemáticos. Por sus características y flexibilidad se han ido desarrollando laboratorios virtuales en el ámbito docente, pero no todas las áreas cuentan con tantas posibilidades o facilidades como en la electrónica. La mayoría de los laboratorios accesibles desde Internet que hay en la actualidad dentro de la enseñanza a distancia o formación online, son virtuales. El laboratorio que se ha desarrollado tiene como principal ventaja la realización de prácticas controlando instrumentos y circuitos reales de forma remota. El proyecto consiste en realizar un sistema software para implementar un laboratorio remoto en el área de la electrónica analógica, que pueda ser utilizado como complemento a las actividades formativas que se realizan en los laboratorios de los centros de enseñanza. El sistema completo también consta de un hardware controlado mediante buses de comunicación estándar, que permite la implementación de distintos circuitos analógicos, de tal forma que se pueda realizar prácticas sobre circuitos físicos reales. Para desarrollar un laboratorio lo más real posible, la aplicación que maneja el estudiante es un visor 3D. Con la utilización de un visor 3D lo que se pretende es tener un aumento de la realidad a la hora de realizar las prácticas de laboratorio remotamente. El sistema desarrollado cuenta con un sistema de comunicación basado en un modelo cliente-servidor: • Servidor: se encarga de procesar las acciones que realiza el cliente y controla y monitoriza los instrumentos y dispositivos del sistema hardware. • Cliente: sería el usuario final, que mediante un visor 3D comunica las acciones a realizar al servidor para que éste las procese. Practices in laboratories are a very important part of training in all educational programs. Despite this importance, the establishment of a laboratory is not an easy task, since the fact of equipping a laboratory can be a great economic budget, both initial and subsequent spending. As a solution, appears the education at distance (online), and in particular the virtual labs, namely simulations of a real laboratory by using mathematical models. Virtual laboratories in the field of teaching have been developed for its features and flexibility, but not all areas have so many possibilities or facilities as in electronics. The most accessible laboratories from the Internet that are currently accessible within the distance or e-learning (on-line) are virtual. The laboratory which has been developed has as a main advantage to make practices or exercises in the fact of controlling instruments and real circuits remotely. The project consists of making a software system in order to implement a remote laboratory in the area of analog electronics that can be used as a complement to the others training activities to be carried out. The complete system also consists of a controlled hardware by standard communication buses that allow the implementation of several analog circuits, in such a way that practices can control real physical circuits. To develop a laboratory as more realistic as possible, the application that manages the student is a 3D viewer. With the use of a 3D viewer, is intended to have an increase in reality when any student wants to access to laboratory practices remotely. The developed system has a communication system based on a model Client/Server: • Server: The system that handles actions provided by the client and controls and monitors the instruments and devices in the hardware system. • Client: The end user, which using a 3D viewer, communicates the actions to be performed at the server so that it will process them.

Evolution and implementation of CDIO initiatives at ETSII-UPM

The School of Industrial Engineering at Universidad Politécnica de Madrid (ETSII-UPM) has been promoting student-centred teaching-learning activities, according to the aims of the Bologna Declaration, well before the official establishment of the European Area of Higher Education. Such student-centred teaching-learning experiences led us to the conviction that project based learning is rewarding, both for students and academics, and should be additionally promoted in our new engineering programmes, adapted to the Grade-Master structure. The level of commitment of our teachers with these activities is noteworthy, as the teaching innovation experiences carried out in the last ten years have led to the foundation of 17 Teaching Innovation Groups at ETSII-UPM, hence leading the ranking of teaching innovation among all UPM centres. Among interesting CDIO activities our students have taken part in especially complex projects, including the Formula Student, linked to the complete development of a competition car, and the Cybertech competition, aimed at the design, construction and operation of robots for different purposes. Additional project-based learning teamwork activities have been linked to toy design, to the development of medical devices, to the implementation of virtual laboratories, to the design of complete industrial installations and factories, among other activities detailed in present study. The implementation of Bologna process will culminate at ETSII-UPM with the beginning of the Master’s Degree in Industrial Engineering, in academic year 2014-15. The program has been successfully approved by the Spanish Agency for Accreditation (ANECA), with the inclusion of a set of subjects based upon the CDIO methodology denominated generally “INGENIA”, linked to the Spanish “ingeniar” (to provide ingenious solutions), also related etymologically in Spanish with “ingeniero”, engineer. INGENIA students will live through the complete development process of a complex product or system and there will be different kind of projects covering most of the engineering majors at ETSII-UPM.

Laboratorios virtuales y docencia de la automática en la formación tecnológica de base

Recientemente, ha surgido un interés por aprender a programar, debido a las oportunidades profesionales que da este tipo de estudios universitarios. Es fácil de entender porque el número de trabajos para programadores e ingenieros informáticos está creciendo rápidamente. Por otro lado, un amplio grupo de psicólogos opinan que el pensamiento computacional es una destreza fundamental para cualquiera, no sólo para los ingenieros informáticos. Para leer, escribir y realizar operaciones aritméticas, deberíamos utilizar el pensamiento computacional y por lo tanto, para desarrollar todas las habilidades analíticas de los niños. Es necesario cambiar los requerimientos de las destrezas necesarias para trabajar, los nuevos trabajadores necesitarán destrezas más sofisticadas en ciencias, matemáticas, ingeniería y tecnología. Consecuentemente, los contenidos sobre Tecnología de la Información tales como electrónica, programación, robótica y control se incrementan en la educación tecnológica en enseñanza secundaria. El desarrollo y utilización de los Laboratorios Virtuales de Control y Robótica ayuda a alcanzar este objetivo. Nos vamos a centrar en control y robótica porque un proyecto de control y robótica incluye contenidos de otras tecnologías tales como electrónica, programación, … Se ha implementado un sitio web con Laboratorios Virtuales de Control y Robótica. En este trabajo, se muestran seis grupos de laboratorios virtuales para la enseñanza del control y la robótica a niveles preuniversitarios. Estos laboratorios virtuales han sido usados para la docencia de alumnos de enseñanza secundaria. Las estadísticas del proceso de enseñanza-aprendizaje permiten validar ciertos aspectos de dicho trabajo. Se describen dichos laboratorios y la mejora del aprendizaje en cuanto a conocimientos procedimentales y conceptuales, así como la mejora de la interactividad respecto al aprendizaje con análogas aplicaciones con objetivos de aprendizaje idénticos, pero careciendo de la componente de laboratorio virtual. Se explican algunas de las experiencias realizadas con los alumnos. Los resultados sugieren, que dentro de la educación tecnológica de la educación secundaria, los laboratorios virtuales pueden ser explotados como un efectivo y motivacional entorno de aprendizaje. ABSTRACT Recently, there has been a surge of interest in learning to code, focusing especially on career opportunities. It is easy to understand why: the number of jobs for programmers and computer scientists is growing rapidly. On the other hand, the psychologists think that computational thinking is a fundamental skill for everyone, not just for computer scientists. To reading, writing, and arithmetic, we should add computational thinking to every child’s analytical ability. It is necessary to change workforce requirements mean that new workers will need ever more sophisticated skills in science, mathematics, engineering and technology. Consequently, the contents about Information Technology as well as electronics, coding, robotics and control increase in Technology Education in High School . The development and utilization of the Virtual Laboratories of Control and Robotics help to achieve this goal. We focus on control and robotics because a control and robotics project includes other technologies contents like electronics, coding,... A web site with Virtual Laboratories of Control and Robotics was implemented. In this work, six groups of virtual laboratories for teaching control and robotics in preuniversity level are shown. These Virtual Laboratories were used for teaching students at high school. The statistics of teaching-learning process allow to check some issues of this work. The laboratories, the improvement of learning (concepts and procedures) and interactivity are described and are compared to similar applications. They share identical learning objectives but they lack the virtual laboratory aspect. Some experiences with students are explained too. The results suggest that within high school technology education, virtual laboratories can be exploited as effective and motivational learning environments.

Web-based OERs in Computer Networks

Learning and teaching processes are continually changing. Therefore, design of learning technologies has gained interest in educators and educational institutions from secondary school to higher education. This paper describes the successfully use in education of social learning technologies and virtual laboratories designed by the authors, as well as videos developed by the students. These tools, combined with other open educational resources based on a blended-learning methodology, have been employed to teach the subject of Computer Networks. We have verified not only that the application of OERs into the learning process leads to a significantly improvement of the assessments, but also that the combination of several OERs enhances their effectiveness. These results are supported by, firstly, a study of both students’ opinion and students’ behaviour over five academic years, and, secondly, a correlation analysis between the use of OERs and the grades obtained by students.

Synchronous collaboration of virtual and remote laboratories

Virtual and remote laboratories(VRLs) are e-learning resources which enhance the accessibility of experimental setups providing a distance teaching framework which meets the student's hands-on learning needs. In addition, online collaborative communication represents a practical and a constructivist method to transmit the knowledge and experience from the teacher to students, overcoming physical distance and isolation. Thus, the integration of learning environments in the form of VRLs inside collaborative learning spaces is strongly desired. Considering these facts, the authors of this document present an original approach which enables user to share practical experiences while they work collaboratively through the Internet. This practical experimentation is based on VRLs, which have been integrated inside a synchronous collaborative e-learning framework. This article describes the main features of this system and its successful application for science and engineering subjects.
