BACKGROUND 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? 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 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.)

FINDINGS The key findings from the 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 PBL 1.

KEY 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 publications "A Tiny Adventure: the introduction of problem based learning in an undergraduate chemistry course."

THE 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)

Creative Commons Licence THE 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 at Leicester, Edinburgh and Huddersfield The problem is based on the search for a sustainable solution to a nation’s energy needs UnitSkills 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

ASSESSMENT 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 DEVELOPMENT The development of draft problems took place July-December 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 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) 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) 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
