Developing and trialling PBL resources for undergraduate
chemistry students

BACKGROUNDBACKGROUND
• PBL approach introduced to chemistry teaching at Leicester in 2007 as part of the HEA/RSC ‘Chemistry for our Future’ project
• Initially we used content based on existing i-Science courses for use in year 1 of our degree
• Since 2007 we have modified the problems that we use in the year 1 module. We have also increased the amount of PBL in the course
WHY PBL?WHY PBL?
Our original aims were:
• To encourage students to engage with the subject at a deeper level
• To allow students to see how to apply abstract chemical concepts to real-world situations
• To embed the development of workplace skills in the chemistry curriculum
PBL IN YEAR ONEPBL IN YEAR ONE
The key features of our original implementation were:
• Problems combined some existing resources with custom written material
• Academic staff and postgraduates were used as facilitators – overseen by an educational developer
• PBL unit ran for 10 weeks in a first semester year one inorganic and physical chemistry module – problems covered core chemistry (bonding, states of matter, etc.)
FINDINGSFINDINGS
The key findings from the 2007-2011 period included:
• The use of PBL in year 1 had an impact on student retention (an increase from 83% to 89% in spite of an increased student intake)
• Students appreciated the development of transferable (workplace) skills “Teaches you to work with different group members” and that it “reflects industry”1
• Student performance was at least as good as it was before the introduction of PBL1. A Nijjar, Robert Ward, “Formative Evaluation of Strand 3.2 of ‘Chemistry for our Future”, Centre for Recording Achievement, 2008.

KEY LESSONSKEY LESSONS
During this period we learnt some important lessons:
• The resource has to be realistic! Use a consultant to help write it if necessary
• To ensure sustainability, teaching by PBL must be efficient in terms of staff and student time and effort
• There must be plenty of opportunities to give student feedback
• Key findings summarised in two publications2-3

THE CHEMISTRY OF ENERGYTHE CHEMISTRY OF ENERGY
In 2011 we made two successful bids to develop a series of new PBL resources as part of the National HESTEM project:
• The Chemistry of Energy – developed by DPW in collaboration with a consultant who had industrial experience (Dr Kevin Parker, KKI Associates Ltd)
• Chemistry’s Frontiers – developed by a Leicester based team (DPW with Dr Sarah Gretton and Dr Carys Bennett)

THE CHEMISTRY OF ENERGYTHE CHEMISTRY OF ENERGY
• The Chemistry of Energy - a 5 credit resource which aims to challenge the popular perception that chemistry’s benefit to society is confined to medicine• Resource piloted in 2011-12 at Leicester, Edinburgh and Huddersfield• The problem is based on the search for a sustainable solution to a nation’s energy needs
Unit Skills areas
Power Generation • Solar Chemistry• Nuclear Power• Organic chemistry and Thermodynamics• Rare Earth Chemistry• Carbon capture technology
Environmental impact and societal issues
• Environmental impact including security of supply and the effect of power generation/usage on atmospheric chemistry
Energy Conservation
• Materials chemistry• The chemistry and physics of power transmission
All Problems • Workplace skills – communication, problem-solving, teamwork, critical thinking, independent learning, etc. • Problem solving strategy
ASSESSMENTASSESSMENT
As well as the scientific learning outcomes, The Chemistry of Energy has a strong focus on the development of communication skills:• Students give a press conference• Students prepare written reports in the form of articles and letters• Students use a spreadsheet model to calculate the energy demands of a nation
PROBLEM DEVELOPMENTPROBLEM DEVELOPMENT
• The development of draft problems took place July-December 2011.
• An RSC advisory panel helped ensure authenticity of the scenarios used in the resources
• Draft resources were trialled and reviewed (by Professor Simon Belt) in early 2012
• Final resources were submitted in June 2012
HOW THE PROBLEM WAS USEDHOW THE PROBLEM WAS USED
Two different approaches were used during the trial of the problem:
• At Leicester – the problem was run in three workshops (each of two hour duration) in a year two communication module
• At Huddersfield – the problem was run as a day long workshop in a year three industrial skills module
EVALUATION (LEICESTER)EVALUATION (LEICESTER)
• 71.4 % of respondents agreed that the problem was interesting
• 85.7 % of respondents agreed that this was a useful way of learning how to communicate science
• “I thought this module was very useful, because I reckon employers always look for scientists that know how to communicate their words effectively and for all kinds of audience”
EVALUATION (HUDDERSFIELD)EVALUATION (HUDDERSFIELD)
• 100 % of (24) students agreed that the scenario was interesting
• Over 90 % of students stated that they liked working in teams
• Over 70 % of students agreed that they were more comfortable about talking in public after this problem
• “Overall, I think this is an excellent scenario. The resource provides just enough details to get started” Dr Christine Lamont
