Advancing science by enhancing learning in the laboratory (ASELL)

Final report of the the Advancing Science by Enhancing Learning in the Laboratory (ASELL) project. 

Most researchers agree that the laboratory experience ranks as a significant factor that influences students’ attitudes to their science courses. Consequently, good laboratory programs should play a major role in influencing student learning and performance. The laboratory program can be pivotal in defining a student's experience in the sciences, and if done poorly, can be a major contributing factor in causing disengagement from the subject area. The challenge remains to provide students with laboratory activities that are relevant, engaging and offer effective learning opportunities.

The Advancing Science by Enhancing Learning in the Laboratory (ASELL) project has developed over the last 10 years with the aim of improving the quality of learning in undergraduate laboratories, providing a validated means of evaluating and improving the laboratory experience of students, and effective professional development for academic staff. After successful development in chemistry and trials using the developed principles in physics and biology, the project, with ALTC funding, has now expanded to include those disciplines.

The launching pad for ASELL was a multidisciplinary workshop held in Adelaide in April, 2010. This workshop involved 100 academics and students, plus 13 Deans of Science (or delegates), covering the three enabling sciences of biology, chemistry and physics. Thirty-nine undergraduate experiments were trialled over the three days of the workshop. More importantly, professional development in laboratory education was developed in the 42 academic staff that attended the workshop.

Following the workshop, delegates continued to evaluate, develop and improve both individual experiments and whole laboratory programs in their home institutions, mentored by the ASELL Team. Some highlights include:
- more than 15,000 student surveys carried out by delegates during 2010/11
- 10 whole lab programs were surveyed by delegates
- 4 new ASELL-style workshops, conducted by ASELL-trained delegates were run in 2010/11
- more than 100 ASELL-tested experiments available on the website (www.asell.org)
- ASELL workshops conducted in Philippines, Ireland in 2010, and planned in the USA and Thailand for 2011
- significant improvement in student evaluation of whole laboratory programs and individual experiments measured in universities using the ASELL approach
- high profile of ASELL activities in the Australian Council of Deans of Science (ACDS)
- research project on the misconceptions of academic staff about laboratory learning completed
- significant research on student learning in the laboratory, and staff perceptions of student learning have been carried out during 2010/11
- research results have been benchmarked against staff and students in the USA.

The biggest unresolved issue for ASELL is one of sustainability in the post-ALTC funding era. ASELL will make a series of recommendations to the ACDS, but the future of the program depends, to a large part, on how the ACDS responds.

The signature pedagogy in chemistry education

Laboratories are the signature pedagogy in chemistry education. The chemical sciences are based in investigations that are reproducible, and objectively testable. Some investigations might involve testing a hypothesis – does a carbonate produce carbon dioxide gas when reacted with acid? Other activities may not have an obvious hypothesis – how much salt is in this detergent package? Nevertheless, laboratory work is a distinctive part of science generally, and of chemistry in particular.

Laboratory work is a significant part of working in the chemistry profession. The best way for students to learn what scientists do, is to do what scientists do. The only way to conduct a laboratory investigation is to get into a laboratory and to do it!

Learning and doing chemistry in a laboratory is an important and irreplaceable part of a chemistry education.

Improving laboratory learning

It has been most encouraging to see science (and innovation)at the forefront of Australian domestic politics in recentmonths. It is also reassuring to see broader bipartisanagreement from the major political parties on the importance ofscience and research to the nation’s future. Governments maychoose to prioritise the areas of scientific endeavour thatwarrant greater support but the acknowledgement by ourpolitical leaders (federal and state) that science and innovationis vital for the nation’s future has not always been forthcoming.The funding mechanisms (e.g. grant schemes) and businessincentives (e.g. taxation) put in place by governments areimportant catalysts of ideally spontaneous processes leading toinnovation and economic advances. However, this pathway isvery complicated.

Distance learning for laboratory practical work in microcontrollers

This paper presents a simple and relatively straightforward solution to the problems of equity in laboratory practical exposure between distance-education students and their traditional, on-campus, fellow cohort. This system has been implemented for the past five years in a university that is amongst the leaders in distance education delivery and has proved to be extremely successful and very well accepted by all students. While the intention was to allow distance education students easy access to the required laboratory practical content of the course, the solution found has proved to have many advantages for the on-campus students. Although this specific implementation is based upon microcontroller technology units in an engineering degree course, the methodology is easily transferable to other disciplines and courses.

A case for a mobile architecture and built environment laboratory

Deakin University and other research and industry partners have recently won a grant for the establishment of a Mobile Architecture and Built Environment Laboratory (MABEL). MABEL provides the first means of integrated, on-site measurement of the key aspects of the built environment (power, sound, light and comfort) using the latest instrument technology. There exists an ongoing need to establish a versatile and comprehensive in-situ testing facility for built internal environments, for the provision of research, education, training and technology diffusion. The ability to make on-site measurements across the environmental spectrum is unique and important. Individual measurements might demonstrate improved lighting performance, reduced power consumption, and improved ventilation or better building acoustics. More importantly, an integrated perspective will address an interaction in terms of energy efficiency and overall occupant comfort. H is recognised that many of the parameters we can measure with existing instrumentation remain unresolved regarding their diagnostic significance on occupant health, comfort and productivity. Also, developed standards for in-situ measurement are at an emerging state, in the delivery of reliable and useful assessment methods. This paper discusses the inception and role of the MABEL facility for building research, learning and teaching.

Achieving greater feedback and flexibility using online pre-laboratory exercises with non-major chemistry students

Compulsory online pre-laboratory exercises were required of non-major, first-year university chemistry students in response to poor student preparation for laboratory sessions. The online pre-laboratory exercises were designed to be straightforward, endeavoring to help students maximize the benefits of the introductory laboratory class. Diagrams and pictures were included in the exercises to improve descriptions. Students were allowed multiple attempts with immediate feedback provided to help them learn from their mistakes. The study is a descriptive account of students' perceptions of the impact of online pre-laboratory exercises on their learning. Students recognized the value of the exercises in improving their organization, their preparedness for the laboratory class, and their understanding of the chemistry concepts of the weekly experiments. The increased flexibility of doing pre-laboratory exercises online and the increased feedback to students were two important aspects of this project that nearly all students recognized as being beneficial to their learning.

Providing a practical education for off-campus engineering students

This paper considers the provision of laboratory-practicals for distance-education students in engineering degree programmes. The authors discuss the role of laboratory-practical work in the curriculum and reflect on five methods that can be used to ensure off-campus students have an equivalent practical experience as the traditional on-campus cohort. On-campus sessions, videotapes (or ‘on-line’ movie-clips), computer simulations, home experiment kits and laboratories controlled over the internet are covered. Some examples are given to show how these can be incorporated into the curriculum. A case study then discusses the problem of (and an exemplar solution to) delivering the laboratory-practical components of two microcontroller units offered at Deakin University – a leading provider of distance-education in Australia. In doing so, it leads the reader through the solution process and cites some constraints that drive the choice of model - for example, cost considerations and the need for relevant didactic materials.

NewsLink Indiana : a learning laboratory for the news industry

The broadcast news industry has many questions about convergence and how best to operate in a world of rapidly changing digital technology. Some of the key issues the industry ponders are how to innovate in a climate of increased competition, how best to structure a converged media operation and how to produce quality journalism yet keep costs under control. This paper tracks the introduction of a "learning laboratory" at Ball State University in Indiana designed to answer these and other questions. The paper outlines the theories and concepts behind the development of a converged newsroom staffed by professionals and students in an immersion education program. It uses qualitative methods initially because these are most appropriate for the project at this stage of its development.

An investigation into the adoption of CDIO in distance education

The Conceive, Design, Implement and Operate Initiative (CDIO) uses integrated learning to develop deep learning of the disciplinary knowledge base whilst simultaneously developing personal, interpersonal, product, process and system building skills. This is achieved through active and experiential learning methods that expose students to experiences engineers will encounter in their profession. These are incorporated not only in the design-build-test experiences that form a crucial part of a CDIO programme but also in disciplinefocused studies. Active and experiential learning methods are, of course, more difficult to incorporate into distance education. This paper investigates these difficulties and the implications in providing a programme that best achieves the goals of the CDIO approach through contemporary distance education methods.

First, the key issues of adopting the CDIO approach in conventional oncampus courses are considered with reference to the development of the CDIO engineering programmes at the University of Liverpool. The different models of distance based delivery of engineering programmes provided by the Open University in the UK, and Deakin University and the University of Southern Queensland in Australia are then presented and issues that may present obstacles to the future adoption of the CDIO approach in these programmes are discussed.

The effectiveness and suitability of various solutions to foreseen difficulties in delivering CDIO programmes through distance education are then considered. These include the further development, increased use and interinstitutional sharing of technology based facilities such as Internet facilitated access to laboratory facilities and computer aided learning (CAL) laboratory simulations, oncampus workshops, and the development of a virtual engineering enterprise.

Chemical education research

Every field of knowledge has two aspects: a practice component, and research into the advancement of the discipline. Chemical education is the same. Chemical education research (CER) aims to evaluate improvements and innovation in practice and also investigate how students learn chemistry. Examples illustrate the scope of CER, with analogies to better well-known examples of research in chemistry.

One recurring theme in chemical education is the improvement of existing laboratory exercises, the development of new laboratory exercises, and the testing of the activities to ensure their scientific validity and robustness, and finally evaluation and feedback to assess the effectiveness of the experiment by students and teaching staff.

Another active area of research is the analysis of curriculum in terms of logical versus psychological progressions of topics order, and trials on better sequences of topics for better outcomes.

have lead to advances in chemistry, with microwave-assisted synthesis, microfluidic devices, and better spectrometers to name just a few. So too, advances in technology have changed the practice of chemical education.

Other CER has examined new uses for mobile phones, using podcasts to enhance lectures, as flashcards, or to access chemistry resources, student-created videos and photo blogs, and other advances in technology.

Yet another area of CER is in the development and validation of these survey instruments.

Research is about collecting proof to support or refute a hypothesis. Chemical education research is no different. Chemical education seeks to improve the learning of chemical science. Chemical education research collects data to evaluate whether a particular course of action is good or bad for learning.

Physics practicals for distance education in an undergraduate engineering course

BACKGROUND : Providing engineering practicals to undergraduates by means of distance education is a significant challenge. The past 30 years have seen the rapid development of the distance education. For many years, Deakin University has offered a full Bachelor of Engineering degree programme via distance education. All first-year students study a unit in physics. This unit includes practicals. Providing practical experiences to students is distance education’s greatest challenge.

PURPOSE : The purpose of this work was to develop the means for off-campus students to complete practical exercises in first-year engineering physics. The solution to the problem also had to comply with accreditation requirements set by Engineers Australia.

METHOD : The long-term solution to the problem was running on-campus lab classes either on weekends or as part of the annual first-year residential school for engineering professional practice. Students work was assessed by means of standard laboratory reports. On-campus marks and off-campus lab marks have been collected and compared over the past 12 years.

RESULTS : The results indicate that the off-campus lab experience is similar to the on-campus experience. Marks for the two cohorts were comparable. Those few students who completed their pracs at home faced and overcame significant challenges.

CONCLUSIONS : We found that performance in their lab reports for off-campus students was similar to that of the on-campus students. Accreditation requirements has shifted the focus from developing activities that students could perform at home to offering timely and efficient on-campus lab classes for off-campus students. Future work will focus on on-campus lab classes in accordance with accreditation requirements and perhaps on-line broadcasts of prac classes for those students who cannot attend lab on-campus.

Undergraduate electronics students' use of home experiment kits for distance education

Laboratory practicals form an essential component in any electronics or electrical engineering course. Many students choose to study engineering by means of distance education. Providing such students with effective and manageable practical experience has always been a significant challenge for those involved in providing distance education. Our university has employed an experimental electronics kit for teaching laboratory skills to distance-education students over the past several years. The chief limitation of the early kit was the inability to use it for performing AC experiments without an additional AC signal generator and an oscilloscope. We now supply distance-education students with the original components pack, and an additional “HELP” kit which contains the signal generator, PC-oscilloscope, a basic multimeter, logic probe, software and documentation. The combined kits allow these students to perform basic DC and AC electronics experiments at home in both freshman and sophomore electronics courses. A more recent development is introducing a small robot platform intended to enhance the student experience and interest in electronics and mechatronics, while still covering the basic skills necessary for the engineer-in-training. Distance-education students receive an updated experimental kit containing the robot, other equipment and components to allow them to complete a fuller suite of practical exercises in electronics in their first two years of study. Within this paper, we present these developments in our HELP kit and also make comparisons between on-campus and off-campus performance.
