Laboratory-based courses play a critical role in scientific education. Automation is changing the nature of these laboratories, and there is a long-running debate about the value of hands-on versus simulated laboratories. In addition, the introduction of remote laboratories adds a third category to the debate. Through a review of the literature related to these labs in education, the authors draw several conclusions about the state of current research. The debate over different technologies is confounded by the use of different educational objectives as criteria for judging the laboratories: Hands-on advocates emphasize design skills, while remote lab advocates focus on conceptual understanding. We observe that the boundaries among the three labs are blurred in the sense that most laboratories are mediated by computers, and that the psychology of presence may be as important as technology. We also discuss areas for future research.

Hands-on, simulated, and remote laboratories: A comparative literature review

Remote laboratories have been introduced during the last few decades into engineering education processes as well as integrated within e-learning frameworks offered to engineering and science students. Remote laboratories are also being used to support life-long learning and student's autonomous learning activities. In this paper, after a brief overview of state-of-the-art technologies in the development of remote laboratories and presentation of recent and interesting examples of remote laboratories in several areas related with industrial electronics education, some current trends and challenges are also identified and discussed.

Current Trends in Remote Laboratories

This review presents the first attempt to synthesize recent (post-2005) empirical studies that focus on directly comparing learning outcome achievement using traditional lab (TL; hands-on) and non-traditional lab (NTL; virtual and remote) participants as experimental groups. Findings suggest that most studies reviewed (n?=?50, 89%) demonstrate student learning outcome achievement is equal or higher in NTL versus TL across all learning outcome categories (knowledge and understanding, inquiry skills, practical skills, perception, analytical skills, and social and scientific communication), though the majority of studies (n?=?53, 95%) focused on outcomes related to content knowledge, with most studies (n?=?40, 71%) employing quizzes and tests as the assessment instrument. Scientific inquiry skills was the least assessed learning objective (n?=?4, 7%), and lab reports/written assignments (n?=?5, 9%) and practical exams (n?=?5, 9%) were the least common assessment instrument. The results of this review raise several important concerns and questions to be addressed by future research. Data supports equal or greater outcome achievement in virtual/remote labs vs. hands-on.A categorization tool (KIPPAS) is presented for meaningful outcome comparisons.The Knowledge and understanding (K) outcome of the KIPPAS tool is most frequently assessed.Quizzes/exams are the most frequently used tools for evaluating outcome achievement.

Learning outcome achievement in non-traditional (virtual and remote) versus traditional (hands-on) laboratories

Laboratory experimentation plays an essential role in engineering and scientific education. Virtual and remote labs reduce the costs associated with conventional hands-on labs due to their required equipment, space, and maintenance staff. Furthermore, they provide additional benefits such as supporting distance learning, improving lab accessibility to handicapped people, and increasing safety for dangerous experimentation. This paper analyzes the literature on virtual and remote labs from its beginnings to 2015, identifying the most influential publications, the most researched topics, and how the interest in those topics has evolved along the way. To do so, bibliographical data gathered from ISI Web of Science, Scopus and GRC2014 have been examined using two prominent bibliometric approaches: science mapping and performance analysis.

Virtual and remote labs in education

Economic pressures on universities and the emergence of new technologies have spurred the creation of new systems for delivering engineering laboratories in education, in particular simulations and remote-access laboratory systems. Advocates of simulation argue that physical labs needlessly consume university space and students' time. However, proponents of hands-on laboratories argue that student engineers should be exposed to real environments. Remote laboratories have appeared as a third option. These laboratories are similar to simulation techniques in that they require minimal space and time, because the experiments can be rapidly configured and run over the Internet. But unlike simulations, they provide real data. Studying the relative effectiveness of these modes of delivering student laboratories is complex, for the underlying technology of the laboratory is just one of many possible factors that could influence effectiveness. For example, the interface to the equipment may be of importance, as might the discussions students have among themselves. This paper presents a model for testing the relative effectiveness of engineering laboratories in education that takes account of these and other factors. The results are presented for an assessment study comparing versions of remote labs versus hands-on labs in a junior-level mechanical engineering course on machine dynamics and mechanisms. The results suggest that students learned lab content information equally well from both types of laboratories, and that they have a realistic understanding and appreciation of the practical advantages of remote laboratories.

A model for evaluating the effectiveness of remote engineering laboratories and simulations in education

During the last decade the exponential expansion of the Internet has had an enormous impact on the tertiary education sector. The new technology has brought a significant improvement in communication within the academic community and has improved students' learning experiences. However, one of the most important factors in forming the engineering graduate qualities is the practical component of the engineering curriculum. Many software packages have been developed for the simulation of real experiments and although very useful, none of them are as effective as learning from undertaking real experimental work. Remote laboratories offer all the advantages of the new technology, but are often a poor replacement for real laboratory work. In this paper we present a remote laboratory called NetLab, developed at the University of South Australia. With its specially designed graphical user interface it offers students all the advantages of a real laboratory environment.

Remote laboratories versus virtual and real laboratories

Three key issues should be addressed to enable universities to deliver engineers who have a solid documented laboratory experience enabling them to design goods and services complying with the requirements of a sustainable society. First, introduce learning objectives of engineering instructional laboratories in courses including laboratory components. Second, implement individual student assessment. Third, introduce free access to online experimental resources as a supplement to the equipment in traditional laboratories. Blekinge Institute of Technology (BTH) in Sweden and the University of South Australia (UniSA) have created online laboratory workbenches for electrical experiments that mimic traditional ones by combining virtual and physical reality. Online workbenches not only supplement traditional ones, but they can also be used for low-cost individual assessment. BTH has started a project disseminating the BTH workbench concept, The Virtual Instrument Systems in Reality (VISIR) Open Laboratory Platform, and invites other universities to set up replicas and participate in further development and standardization. Further, online workbenches offer additional learning possibilities. UniSA has started a project where students located in different countries can perform experiments together as a way to enhance the participants' intercultural competence. This paper discusses online laboratory workbenches and their role in an engineering education appropriate for a sustainable society.

On Objectives of Instructional Laboratories, Individual Assessment, and Use of Collaborative Remote Laboratories

Practical skills are important attributes of every engineering graduate. The Internet has provided tertiary education with the opportunity to develop innovative learning environments. The teaching and learning of practical skills has gained a new dimension with the emergence of remote laboratories. The rapidly growing number of remote laboratories (RL) worldwide is the evidence that the educational community has recognized their potential to develop into a creative, flexible, engaging, and student-cantered learning environment. Even a brief review of the existing RLs shows a large diversity in their structure, design and implementation. However, not many researchers disclose how their RLs are integrated within their curricula. Therefore, an important question still remains to be answered: how to optimize the design of RLs and their integration in a course curriculum for the best learning outcomes? This problem is particularly important when RLs are used in teaching 1st year students who have limited technical knowledge and practical experience in using real equipment. In this paper we would like to share our experiences with NetLab, an RL developed at the University of South Australia (UniSA) for teaching 1st year engineering students and make recommendations for improvements in teaching practices based on it.

Remote laboratories (RL) are becoming a common educational environment at a growing number of universities worldwide. However, there are no standards guiding the development of remote laboratories, so each of about 120 currently existing RLs is a unique development. In this paper we do not introduce a standard, but we rather showcase an effective example that has been developed at the University of South Australia (UniSA) and adopted elsewhere, so it may possibly be proposed as a standard graphical user interface (GUI) for effective interaction between users and instruments in remote laboratories.

Remote laboratory netlab for effective interaction with real equipment over the internet

Over the past few years many universities worldwide have introduced a common first year for all engineering disciplines. This is despite the opinion of many academics that large classes have negative effects on the learning outcomes of first year students. The University of South Australia is also faced with low motivation amongst engineering students studying non-major courses. In 2006, a project-based laboratory was successfully introduced for first year students enrolled in electrical disciplines, which increased student satisfaction, reduced the attrition rate and improved students’ success rate. This paper presents the experiences with the project-based laboratory's implementation in three different projects in the common first year course, Electrical and Energy Systems, where each project aims to increase the motivation of students in one of three disciplines: electrical, mechanical or civil engineering.
