Percepciones de los estudiantes sobre el uso de los laboratorios virtuales en mecánica de suelos

Este artículo muestra los resultados de adoptar laboratorios virtuales en la asignatura de mecánica de suelos en los pregrados de ingeniería civil e ingeniería agrícola en la Universidad Nacional de Colombia. Desde la perspectiva de los estudiantes, presenta de qué manera los laboratorios contribuyen a la comprensión y aplicación de conceptos en la solución de problemas relacionados con la mecánica de suelos. Se exploraron los resultados de la percepción de autoeficacia de los estudiantes así como de su percepción sobre los laboratorios virtuales en relación con las características socio-demográficas de los estudiantes. La evidencia recolectada sugiere que los estudiantes encuentran que los laboratorios contribuyen a potenciar sus habilidades de investigación, de análisis y conocimientos en mecánica de suelos. Los estudiantes que dedicaron mayor tiempo a la asignatura consideran que los laboratorios virtuales permiten desarrollar conceptos y habilidad de análisis y evalúan positivamente el trabajo con estos laboratorios.

CHEMOTION: A gesture based chemistry virtual laboratory with leap motion

AbstractChemistry laboratories are expensive to setup and operate as well as it entails safety issues. However, as technologies develop and new technologies are being produced every day, an advance solution for physical Chemistry laboratories limitation is the use of virtual laboratories. In this paper, we present the design and implementation of a virtual chemistry laboratory system that utilizes gesture computing technology to create an interactive and entertaining laboratory application for pupils. The system is software that works on PCs with the help of Leap motion controller, off‐the‐shelf gesture recognition hardware, to simulate a chemistry laboratory. The system provides number of experiments to perform along with tutorials and quizzes. A preliminary usability evaluation of the system shows the high level of interest from the pupils in using such a system and the positive feedback.

Virtual laboratory enabling projects to work with robots, NC machines, conveyors and other types of objects. The solution is a system for recording special marks under which a computer generates the appropriate object.

ЗАСТОСУВАННЯ ІНТЕРАКТИВНИХ ОНЛАЙНОВИХ МОДЕЛЮВАНЬ ПІД ЧАС ВИКОНАННЯ ЛАБОРАТОРНИХ РОБІТ З ФІЗИКИ

Сучасному вчителю фізики потрібно мати професійні компетентності, що спрямовані на використання інтернет-технологій, пов’язаних з фізичним експериментом. Недостатня кількість методичних матеріалів для вчителів українською мовою призводять до використання вчителями віртуальних лабораторій і комп’ютерних моделювань за традиційними методиками, а не за новітніми інноваційними сучасними педагогічними технологіями, що може обмежити їх використання і значно знизити їх ефективність. В українській методичні літературі практично відсутні відомості щодо оцінювання компетентностей, дослідницьких навичок учнів під час виконання ними лабораторних робіт. Метою статті є опис окремих компонентів методики використання матеріалів веб-сайту з моделювань в шкільному фізичному експерименті та їх оцінювання, зокрема, під час виконання лабораторних робіт.

Virtual Laboratory for Learning Asynchronous Motors in Engineering Degrees

Studies within the European Higher Education Area framework include the acquisition of skills such as the ability to learn autonomously, which requires students to devote much of their time to individual and group work to reinforce and further complement the knowledge acquired in the classroom. To consolidate the results obtained from classroom activities, lecturers must develop tools to encourage learning and facilitate the process of independent learning. The aim of this paper is to present the use of virtual laboratories based on Easy Java Simulations to assist in the understanding and testing of electrical machines.

Virtual laboratory vs. traditional laboratory: which is more effective for teaching electrochemistry?

The use of virtual laboratories has become an increasing issue regarding science laboratories due to the increasing cost of hands-on laboratories, and the increase in distance education. Recent studies have looked at the use of virtual tools for laboratory to be used as supplements to the regular hands-on laboratories but many virtual tools have not been used as replacements. In order to understand the effects of virtual laboratory methods as well as ascertain the effectiveness of our normal lab procedures, we used a virtual versus hands-on scenario for an electrochemistry laboratory. We separated our General Chemistry II Lab students into two groups. Each group completed an electrochemistry lab either through our normal hands-on format or with the use of a virtual lab animation created by the Iowa State Education Group. Pre- and post-test data for conceptual and factual understanding were collected as well as a post-test hands-on setup of an electrochemical cell. There were no significant differences in scores on either the pre-test, post-test, or the hands-on setup test. However, individual item analysis on the tests revealed a significant difference in the use of the salt bridge during the post-test and the hands-on setup activity.

Impacto del laboratorio virtual en el aprendizaje por descubrimiento de la cinemática bidimensional en estudiantes de educación media

Este artículo resume un estudio cuyo propósito fue determinar la incidencia del laboratorio virtual en el aprendizaje de la cinemática bidimensional, para un contexto específico. El estudio es de tipo cuantitativo, con diseño cuasiexperimental, pre-prueba, pos-prueba y grupos intactos, uno de ellos de control. Las pruebas paramétricas permitieron concluir que, en las dimensiones afectiva y cognitiva, existía diferencia significativa a favor de los alumnos que emplearon una estrategia basada en el uso del laboratorio virtual. Para la dimensión procedimental no se encontró diferencia estadísticamente significativa.

The Use of Virtual Laboratories and Other Web-based Tools in a Drug Assay Course

To determine students' perceptions of and performance in a drug assay laboratory course after the addition of Web-based multimedia tools. Video modules and other Web-based tools to deliver instructions and emulate the laboratory set up for experiments were implemented in 2005 to improve student preparation for laboratory sessions and eliminate the need for graduate students to present instructions live. Data gathered from quizzes, final examinations, and post-course surveys administered over 6 years were analyzed. Students' scores on online quizzes after implementation of the virtual laboratories reflected improved student understanding and preparation. Students' perception of the course improved significantly after the introduction of the tools and the new teaching model. Implementation of an active-learning model in a laboratory course led to improvement in students' educational experience and satisfaction. Additional benefits included improved resource use, student exposure to a variety of educational methods, and having a highly structured laboratory format that reduced inconsistencies in delivered instructions.

The Role of Design in Control Engineering Education

In this paper we discuss the role of design in tertiary education linked to professional practice. We give particular emphasis to control engineering. We argue that such education is made more interesting and relevant if it is linked to real world experiences. We point to one mechanism for giving students exposure to real world designs via the use of Virtual Laboratories.

Facilitating process control teaching and learning in a virtual laboratory environment

AbstractThe rapid pace of technological developments and the high cost of engineering equipment, pose several challenges to traditional modes of engineering education. Innovations in education are desirable. In particular, education on practical aspects of engineering and personnel training can be enhanced through the use of virtual laboratories. Such educative experiences allow a student to better understand the theoretical aspects of the discipline in addition to its integration with practical knowledge. In this work, the development, set‐up and application of a virtual twin heat exchanger plant is described. The philosophy and methodology of our approach is described, including the implementation details and our experience in using it. The effectiveness of the platform in educating students and in training industrial personnel is described. © 2002 Wiley Periodicals, Inc.
