Abstract This paper provides a rigorous statistical analysis of the educational effectiveness of a curriculum module pertaining to direct current (DC) motors and motorized systems. Educational interactive multimedia software played an important role in the module, which also included lectures, a design project and other more traditional pedagogics. Pre- and post-tests were administered to measure learning during the module and individual test questions targeted specific areas of the curriculum to determine the contribution of the various resources to the entire learning environment. The data indicate that the module was indeed educationally successful and that the software contributed to the curriculum’s success. The module was particularly effective for promoting learning by female engineering students in the course and mitigated some discrepancies in prior knowledge. Students were also grouped into four preference groups based on analysis of students’ preference questionnaire responses. The data indicate that each preference group responded differently to the various teaching techniques employed in the curriculum.

Laboratory experiments are an important and integral part of the learning experience for undergraduate engineering students. They help the students in getting hands-on experience and in better understanding theoretical concepts. In recent years, a significant number of remotely accessible experiments have been developed and integrated into engineering laboratory courses at many educational institutions worldwide. There exist several approaches and technologies for making experimental hardware accessible via the Internet. This paper will discuss some of the available technologies and a specific method for acquiring data from experimental setups via LabVIEW Virtual Instruments over a network. As an example, a remote experimental apparatus that was developed by upgrading a commercially available air flow rig with remote control and monitoring capabilities is presented. This system is used in a junior-level mechanical engineering course on fluid mechanics. It enables the students to access the experimental setup via the Internet either in real-time or batch mode. For real-time use of the experimental setup, remote panels are used. These remote panels are exactly the same as those that would be used on a local on-site server. They can be run under LabVIEW’s Web server to be observed and controlled by the client via any Internet browser. For the batch-mode use of the experimental setup, on the other hand, simple HTML pages in conjunction with forms are used to generate experimental requests that are sent to the LabVIEW server. This server then places these experimental requests in a queue and executes the appropriate LabVIEW scripts on a first-come first-served basis. This paper will discuss and compare both methods for performing remote laboratory experiments.

Teaching electronics is not only for electrical and electronics students but also for mechanical, aerospace, engineering design, civil and engineering mathematics programmes, which are likely to have electronics units as part of their curriculum. To teach electronics for these non-electronic programmes is very challenging in many aspects. First, the electronics unit has to satisfy the learning outcomes for each programme. Second, the student’s motivation is normally very low since electronics is not the career the students would like to pursue. Third, the timetabling can be an issue when a large number of students are enrolled; for instance, at the University of Bristol, over 340 students are registered for the electronics unit. Due to this large number and the capacity of the electrical laboratory, students will have laboratory experiments timetabled in different weeks and some may have laboratory experiments before the lectures are covered. Finally, a method of assessing this large number of students has to be put into place. In this paper, the content of the unit including the laboratory experiments, the methods of course delivery and the assessment methods are justified. Also, since students learn differently and have a variety of motivations, a combination of teaching methods has to be found to satisfy more students and improve the learning outcomes.

The engineering students understand the engineering concepts effectively when they conduct the experiments in the laboratory. Hence, laboratory is as important as theory; however, the ill-equipped laboratory facilities affect the students’ learnability. The virtual laboratories may help the students overcome the problems faced by them in the conventional laboratory. In India, educational activities during the middle of the semester were affected due to lockdown related to COVID-19. However, the theory classes were conducted online, and educational institutions are finding it difficult to complete the laboratory experiments due to closure of colleges for the students due to COVID-19 pandemic. Hence, we have conducted a faculty development programme for the engineering college faculty members on mechanical engineering virtual laboratories. Similarly, we have trained the mechanical engineering students on fluid mechanics virtual laboratory. We have taken feedback from the participants of these virtual laboratory training programme and analysed it. From the analysis we have observed that more than 90 per cent of the participants were happy about the virtual laboratory and they expressed that their learning process improved with virtual laboratory experiments. Also, they felt that the virtual laboratories can be used till the COVID-19 pandemic issues are solved. Since the vaccine for COVID-19 is not available yet, the virtual laboratories will help the mechanical engineering students to conduct the laboratory experiments for the academic year 2020–2021.

AbstractFrom the established dependence of the brightness decrease of a short-period comet dependence on the perihelion distance of its orbit it follows that part of the surface of these cometary nuclei gradually covers by a refractory crust. The results of cometary nucleus simulation show that at constant insolation energy the crust thickness is proportional to the square root of the insolation time and the ice sublimation rate is inversely proportional to the crust thickness. From laboratory experiments resulted the thermal regime, the gas productivity of the nucleus, covering of the nucleus by the crust, and the tempo of evolution of a short-period comet into the asteroid-like body studied.
