Bhute V, Campbell J, Kogelbauer A, Shah U, Brechtelsbauer Cet al., 2020, Moving to timed remote assessments: the impact of COVID-19 on year end exams in Chemical Engineering at Imperial College London, Journal of Chemical Education, Vol: 97, Pages: 2760-2767, ISSN: 0021-9584

Summative year end assessments area major component of student assessment at the Department of Chemical Engineering, Imperial College London.More than 600 studentsparticipate in over40 different exams during the summer term. At the end of the spring term, the college moved to fully remote operation due to COVID-19, leaving the academic community with the challenge of delivering examinationsremotely. At the time pandemic hit the UK, teaching for allmodules in the department had been completed, the exam timetable had already been published and all exam paperspassed the mandatory external quality review. To implement time-limited remote examsas stipulated by the university, the department decided to proceed with anexisting VLE platformfor submission of answer-sheets.This study highlights stakeholder reflections from the academic and student communityduring the implementation of this approachculminating in a mock examination to gauge readiness of the infrastructure as well as the student population.Our survey found that the majority of students (>80%) managed to follow the written instructionsand readily engaged with scanning technologies and the uploading process.In the main, students did not have to adapt their learning or writing style. All stakeholdersprovided constructive suggestions at the end of the mock exam resulting in a relatively smooth transition to this new mode of examination. This study highlights challenges and reflections on making the summer year end examsremote in a very short timeframein a large and diverse Chemical Engineering department at very short notice.

University rankings have become an important tool to compare academic institutions within and across countries. Yet, they rely on aggregated scores based on subjective weights which render them sensitive to experts’ preferences and not fully transparent to final users. To overcome this limitation, we apply Data Envelopment Analysis (DEA) to evaluate UK universities in the field of chemical engineering as a case study, using data retrieved from two national rankings. DEA is a non-parametric approach developed for the multi-criteria assessment of entities that avoids the use of subjective weightings and aggregated scores; this is accomplished by calculating an efficiency index, on the basis of which universities can be classified as either ‘efficient’ or ‘inefficient’. Our analysis shows that the Higher Education Institutions (HEI) occupying the highest positions in the chemical engineering rankings might not be the most efficient ones, and vice versa, which highlights the need to complement the use of rankings with other analytical tools. Overall, DEA provides further insight into the assessment of HEIs, allowing institutions to better understand their weaknesses and strengths, while pinpointing sources of inefficiencies where improvement efforts must be directed.

Maraj M, Hale CP, Kogelbauer A, Hellgardt Ket al., 2019, Teaming with confidence: How peer connections in problem-based learning impact the team and academic self-efficacies of engineering students

Engineers will routinely work in teams to solve complex problems. Team-working and collaboration are therefore an integral part of engineering education as they offer enhanced opportunities of acquiring both transferable and subject-specific skills. This paper examines the experiences of third-year engineering students studying a design-based module which uses problem-based learning (PBL) as the main pedagogical approach where students work in teams of 5 or 6 to achieve the associated learning outcomes. PBL allows students to not only play an active role in their own learning but also affords the added opportunity of learning with and from each other (peer learning). The success of this experience can however, be impacted by the team efficacy which exists or ensues as part of the process. These interactions can influence academic self-efficacy and a key aim of this paper is to use the students' perceptions of their experiences with PBL to examine the relationships which exist among academic self-efficacy, peer learning and team efficacy within the module. Findings show that a large percentage of students (85%) felt they learned from each other and that this collaborative experience strongly improved their understanding of mechanical design principles. Self-efficacy scales ranging from 0 (cannot do at all) to 100 (highly certain can do) showed that 65% of students rated their average academic self-efficacy across all learning outcomes as high (above 75). This efficacy was positively related to the support received from peers. Only 6% of respondents indicated that they would be confident undertaking the module by themselves and that while peer-to-peer interactions helped with sharing the workload and producing deliverables, they would have been able to successfully tackle the module alone had the time allotted been increased proportionally. This information is valuable as it can inform and direct future module design within our programme in which many modules are team

A curriculum review can be an intricate and arduous process, made more complex due to a myriad of interwoven threads that inform the curriculum. This is often the case in chemical engineering due in part to the accommodation of employer expectations, requirements from accreditation bodies and the multidisciplinary, integrative nature of an engineering degree which depends on students acquiring a wide range of attributes, and which focuses on application and relevancy [1], [2]. In this paper, we present our efforts to review the chemical engineering curricula at a research-intensive higher education institution (HEI)in the UK. This review is being orchestrated by institutional managers to ensure that programmes of study throughout the HEI better reflect student needs and expectations and adhere to a recently revised institutional teaching and learning strategy. This review is also driven by a recognition that the student body has changed with traditional modes of teaching seemingly outdated and ineffective. For example, it has previously been suggested that one of the greatest obstacles to overcome with respect to creating the right type of education for chemical engineers, does not arise from external drivers, but in recognising and responding to internal factors –amounting to fundamental pedagogical shifts in learner behaviour and expectation[1].

Kolade MA, Kogelbauer A, Alpay E, 2008, Adsorptive reactor technology for VOC abatement, Chemical Engineering Science, Vol: 64, Pages: 1167-1177

The use of the monolith as an adsorptive reactor (MAR) is proposed as a viable and novel alternative for VOC disposal. The MAR combines adsorptive separation and catalytic combustion of the VOC in a single reactor unit and is thought to make effective utilisation of energy due to efficient heat integration. Theoretical studies on the feasibility and application of the adsorptive reactor concept for VOC oxidation is presented in this paper. Thus unlike previous work, present studies focus on an exothermic reaction system and the ability of the MAR to control thermal runaway. A two dimensional mathematical model accounting for non isothermal adsorption and reaction, mass transfer limited adsorption kinetics and non linear (Tóth) adsorption equilibria, has been developed. The process is operated cyclically in two steps: adsorption and desorption/reaction. The VOC is fed into the reactor in the adsorption step and captured to produce a pure carrier gas effluent. Concentration and thermal swing is induced in the second step by means of an air feed. The most outstanding feature of the MAR is its ability to prevent thermal runaway whilst maintaining a high VOC conversion. Simulation results indicate that the careful selection of step times for adsorption and desorption, feed temperatures and inlet velocities lead to stability and energy requirements which outperform equivalent conventional designs. The MAR is thermally more stable due to the controlled release of the reactant from the adsorbed phase into the reaction zone, and also the heat integration of endothermic desorption and exothermic reaction.
