Overview
Group-based research projects have been introduced into the BSc Chemistry programme for final year students. Small teams of students investigate different aspects of a research problem, each working on a separate strand. The results are combined and overall conclusions drawn. The team-based approach more closely resembles the nature of research in the chemical industry. The approach can be translated to many other disciplines.
Objectives
- To provide final year students with the opportunity for open-ended investigative laboratory research.
- To work as a team to plan and design a suitable approach and experiments to explore the problem.
- To carry out original research and collate and analyse results.
- To draw conclusions and present the results both orally and as a dissertation.
- To develop a variety of key transferable skills required for the workplace.
Context
All accredited Chemistry programmes must contain individual independent investigative work, historically in the form of a final-year research project. Since the rapid expansion of chemistry undergraduate numbers, many departments have moved from laboratory-based projects to literature reviews or short, open-ended practical work. Group projects provide an alternative approach where undergraduates carry out a worthwhile chemical investigation, with the potential of yielding useful results within the restricted time, and with the limited resources available.
Implementation
A Teaching and Learning Development Fund (TLDF) Grant in 2015 allowed us to appoint two undergraduate students to investigate some potential ideas for research projects over the summer of 2015. The students carried out initial trials into a series of research topics in the broad areas of inorganic, organic, physical and analytical chemistry. On the basis of these preliminary investigations a short briefing sheet was drawn up for each research question, to be used as a starting point for the teams.
Final year students on the BSc Chemistry and BSc Applied Chemistry (NUIST) programmes were invited to select areas of preference in chemistry for their final year project. Students were organised into teams of 3-5 students on the basis of project preferences and undertook two short (five week) projects, the first of which acted as a trial run to allow students to become familiar with an independent research environment. Each team was allocated an academic supervisor to whom they reported their results weekly. During the final week of each project team members discussed their results and prepared a presentation. Students were given feedback on the first presentation to help inform the second. The second project was written as a formal report, with each student writing up their individual investigations and the whole team contributing to the introduction and final discussions and conclusion.
Students were assessed on the basis of their individual laboratory notebook, their oral presentation and project report. They were asked to evaluate their peers’ contributions under a variety of categories to produce a factor which could be used to scale any group component marks.
Impact
In 2015-2016 a total of 12 team-based projects were carried out in 4 different research areas. As the topics were re-visited (i.e. the same topic used more than once), the second group of students were able to carry on the investigation from where the first group finished.
All projects were successful in producing results that the students were able to analyse and discuss. The value of the results to the research question varied significantly with the team and the nature of the project. Students were not penalised if they worked in a project area that did not easily yield positive results: they were advised that their grades depended upon their input into the project and their oral and written communication skills in presenting the project. In the majority of cases the teams worked well to plan and execute experiments that led to conclusive results.
Although the numbers were relatively small in 2015-2016, the team-based approach reduced academic supervision and training time, as one staff member could supervise a team of students. More results were obtained from the team-based approach than when students worked independently. The research questions had to be selected carefully and some preliminary work done, but despite this some of the projects yielded new results that are publishable. Students improved their team working skills significantly and have ample experiences to discuss at interviews.
Reflections
The success of each group project depended to a large extent on the individual supervisor and the group dynamics. Ownership of the project by the supervisor led to more successful outcomes and better group dynamics. It was observed that groups of 4 students seemed to work better than 3 or 5, as research problems often break down to comparing A against B, and therefore workload could be more easily divided. Interestingly, students requested one long project in future rather than two short ones because they felt that with a long project they could really make a meaningful impact with their work.
As the project reports were to be submitted shortly before the exam period, some students were anxious to complete their contributions in good time and found it difficult to work with their peers who had a more relaxed approach. Because of the high weighting (40 credits) on the project, we will require individual project reports in future. In addition, combined group reports were difficult to assess fairly, even with peer evaluation.
Links
The work was presented at the 2nd Enhancing Student Learning Through Innovative Scholarship Conference meeting in June 2016.
The core Part Two undergraduate module, International Business Management and Strategy (MM272), was redesigned on two pillars: teamwork, and social media (Facebook). Formal student evaluations were high and feedback from focus groups with students was very positive – students found the use of Facebook effective and enjoyable, and students felt fully engaged.
Active learning methods were explored, and the Environmental Quality and Well-being module (CEM236EQW), a week intensive module offered by the School of the Built Environment, was amended to incorporate suitable active learning methods, improving student satisfaction and engagement.
