HELP – Home Electronics Laboratory Platform –Development And Evaluation

In response to the COVID pandemic, many of our undergraduate students were supplied with custom development kits to undertake their electronic laboratory activities at home. Following our return to on-campus teaching, we plan to combine on-campus laboratory sessions with at-home experiments taking advantage of both on-campus and at-home experimental work while avoiding some of the limitations experienced during remote teaching. The goal is to embed active learning as a key part of a long-term strategy to enable students to better manage their learning and to maximise the analytical engagement with lecturers in a hybrid blend of on-campus and remote activities. In this paper, we report on three generations of the at-home laboratory kit developed by the author\u27s institute and partners in the Erasmus+ project “Home Electronics Laboratory Platform (HELP)”. The HELP kit comprises a portable signal generator and measurement instrument and a custom electronic board, which includes several functional blocks alongside the usual breadboard for assembling circuits with discrete components. The motivation for the design of each generation is introduced and the desired functionality and its implementation are described. The impact and user experience with the kits have been assessed through student surveys and staff focus groups in the HELP consortium partners. The main themes associated with take-home electronics laboratories have also been explored in a workshop with HELP partners and contributors from other universities across Europe and the USA. This work is summarised and future potential technical and pedagogical developments are outlined

Innovative Engineering Education in Circuits and Systems

Nowadays, the field of microelectronics has become the drive for the advancement of the times, which promotes new demands on the cultivation of the students in colleges and universities. In order to keep up with the trend of the global engineering educational reform, three important reforms in education have been in progress step by step, including classroom teaching, innovative training and virtual laboratories. At first, for enhancing and integrating the existing courses related to the circuit, so that the students can comprehend the existing knowledge much more effectively, an important and effective curriculum reform has been performed by combining “Circuit Analysis” and “Analog Circuit Foundation” into one course; Then, innovative training has been carried out to cultivate the team skills among the students; Finally, in consideration of the rapid development of the electrical and electronic experiment, the conventional laboratory equipment may not satisfy the demand of every student due to financial constraints, therefore, the construction of virtual simulation experiment center is an efficient way to break this bottleneck. As a result, the atmosphere of academic innovation of the pursuit of truth, advocacy of science, brave exploration, dare to practice have been formed in colleges and universities through the above innovative engineering education reform

How to make classrooms creative and open spaces: ARIS games, digital artifacts and storytelling

As part of long-term research into interviewing users and visualizing digital artifacts, we have created a parallel archives of projects in our classroom. Ethnography helps us to discover the temporal trends of interactions with students and with the virtual environment. The outcomes expected motived us to repurpouse stories we co-create with students in a new form, retelling motivations, design, narratives, into a gaming scenario where the use of experiences become more digital and less tangible but always snapshots of their social existence.Peer Reviewe

Laboratorios virtuales y remotos en electrónica y telecomunicaciones: una revisión técnica en educación

Training in analysis of electrical and electronic circuits is a fundamental area in the learning process of future bachelors in areas related to electronics and telecommunications, therefore, preparation in Know-How is a stage that must be part of the process where the evolution of engineering and the fourth industrial revolution have changed not only technology but also the path of teaching.

Vertical And Horizontal Integration Of Laboratory Curricula And Course Projects Across The Electronic Engineering Technology Program

This paper discusses the details of the curricular development effort with a focus on the vertical and horizontal integration of laboratory curricula and course projects within the Electronic Engineering Technology (EET) program at Texas A&M University. Both software and hardware aspects are addressed. A common set of software tools are introduced to the sophomore students in the EET curriculum; these tools are then used in several junior and senior level courses. Through early and repeated exposure to these tools, students learn to use them more effectively to solve various engineering problems in laboratory and course projects. A DC permanent magnetic motor is identified as one of the common hardware platforms for multiple course projects. By using a common platform for different course projects, the students can spend much less time preparing for the course projects. With each course adding different features to the common platform, the learning experience in several courses becomes seamlessly integrated. Surveys were conducted to show that the curriculum development effort improved the efficiency of student learning and enhanced the students’ educational experience.

Remote controlled experiments for teaching over the Internet: A comparison of approaches developed in the PEARL project

The PEARL project has been developing approaches for enabling real-world experiments to be conducted by students working, remotely from the laboratory, over the Internet. This paper describes these approaches and compares and contrasts three specific implementations of them both at the level of the nature of the practical work they support and the technical infrastructures that enables this to be conducted remotely. Initial evaluations by experts and representative student subjects are reported and key lessons for further development work by the project consortium, or others seeking to implement remote experiments, are outlined. Among the lessons learnt is that engineering realities associated with the equipment being used were difficult to accommodate in the generic architecture we initially envisaged. In fact the three implementations described adopted different architecture in their realisation of the PEARL approach. These are commented on in the paper together with notes on their implementation given available technologies

A PORTABLE AND INEXPENSIVE DO-IT-YOURSELF TEMPERATURE SENSOR

Nowadays it is important to have commercial solutions to be used in teaching and research laboratories for the needs. We can have different equipment according to the necessary parameters of control being related to the influence of parameters internal or external to the laboratory practice. However they can't be straightforward to use, their costs can be considerable.  In this context, the do-it-yourself approach is an interesting alternative. In this paper we report the construction of a temperature sensor made by students. Based on a probe taken from a deactivated equipment, the sensor development and validation encompassed its design and building up, the establishment of a connection to a personal computer via USB, the setup of computer-controlled processes, which included remote control, graphical and numerical displaying and signal acquisition, and finally its testing. Tests were performed in water containers with different temperatures, namely boiling, room and ice. The obtained results are comparable to those from a commercial thermometer. This student experiment project allowed not only to contact different disciplines such as chemistry, electronics, and programming but also to gain competencies that can be used outside the class context. We proved it is possible to build tailor-made electronic devices capable of providing useful measurements to chemical purposes old equipment in an inexpensive and trustworthy way
