Feedback for future learning: delivering enhancements and evidencing impacts on the student learning experience

Enhancing the student learning experience through the provision of improved student feedback is both challenging and complex. ‘Feedback for Future Learning’ was a Glasgow Caledonian University(GCU)-wide project intended to enhance feedback practices from both the student and staff perspectives; to ensure greater awareness of, and reflection upon, feedback by students; and to encourage greater use of feedback to inform future student learning. The design, implementation and evaluation of approaches to ‘Feedback for Future Learning’ are described with an emphasis on STEM disciplines. The conceptualisation, design and implementation of a range of student feedback tools and approaches aimed to develop understanding of learning processes, reinforce learning and improve performance. This was achieved through collaboration with the GCU Students’ Association and the establishment of the University Feedback Enhancement Group. A series of generic and bespoke seminars, workshops, individual programme interventions and competitions were used to enhance comprehension of the perception, experience and use of formative and summative assessment feedback by students.   Providing opportunities for reflection and evaluation together with qualitative and quantitative metrics have demonstrated 93% satisfaction with student feedback enhancement workshops, a trebling of engagement with memorable feedback survey initiatives and a 9% increase in National Student Survey assessment and feedback satisfaction. A 16% rise in student satisfaction with the promptness of feedback, a 14% improvement in satisfaction with the detailed comments received and an 8% increase in satisfaction with the helpfulness of comments received were achieved. The lessons learned inform the continuing and sustainable enhancement of the student learning experience for STEM students and the wider University community. Keywords: Feedback, future learning, dialogue, engagement, reflection, enhancemen

Carboranes as model hypercarbon systems; structural and bonding patterns in selected isoelectronic closo-borane and carborane systems; [BnHn](2-), [1-CBn-1Hn](-) and 1,n-C2Bn-2Hn (n=5, 6, 7, 10 or 12)

Computations have been carried out on the title boranes and carboranes, model hypercarbon cluster systems chosen to explore how effectively an individual carbon atom, whilst bonding by a normal 2-electron 2-centre bond to an exo-hydrogen atom, can also bond to sets of three, four or five equivalent boron atoms within a series of carborane clusters which have carbon atoms in axial sites of C3v, C4v or C5v local symmetry. The calculated interatomic distances and bond orders and CH and BH group charges are reported, and the manner in which the introduction of CH units to replace BH− units in closo-borane cages perturbs the distribution of the skeletal electrons in these clusters is discussed

Rheology to guide formulation development of particulate dispersions for automated capsule filling

The rheological properties of pharmaceutical formulations intended for liquid fill hard gelatin capsules are fundamental for their filling performance. Here we used the rheological characteristics of particulate drug formulations to develop formulations suitable for automated capsule filling

Some theorems in combinatorial topology

This thesis consists of four papers: 1. On the fundamental group of an orbit space 2. Transversality for piecewise linear manifolds 3. Transversality for polyhedra 4. Extending triangulations At the beginning of each paper there is an introduction which contains a survey of the problems to be tackled, and statements of the main results obtained. Each paper is presented in a form suitable for publication

Telescopic actions

A group action H on X is called "telescopic" if for any finitely presented group G, there exists a subgroup H' in H such that G is isomorphic to the fundamental group of X/H'. We construct examples of telescopic actions on some CAT[-1] spaces, in particular on 3 and 4-dimensional hyperbolic spaces. As applications we give new proofs of the following statements: (1) Aitchison's theorem: Every finitely presented group G can appear as the fundamental group of M/J, where M is a compact 3-manifold and J is an involution which has only isolated fixed points; (2) Taubes' theorem: Every finitely presented group G can appear as the fundamental group of a compact complex 3-manifold.Comment: +higher dimension

Bound Chains of Tilted Dipoles in Layered Systems

Ultracold polar molecules in multilayered systems have been experimentally realized very recently. While experiments study these systems almost exclusively through their chemical reactivity, the outlook for creating and manipulating exotic few- and many-body physics in dipolar systems is fascinating. Here we concentrate on few-body states in a multilayered setup. We exploit the geometry of the interlayer potential to calculate the two- and three-body chains with one molecule in each layer. The focus is on dipoles that are aligned at some angle with respect to the layer planes by means of an external eletric field. The binding energy and the spatial structure of the bound states are studied in several different ways using analytical approaches. The results are compared to stochastic variational calculations and very good agreement is found. We conclude that approximations based on harmonic oscillator potentials are accurate even for tilted dipoles when the geometry of the potential landscape is taken into account.Comment: 10 pages, 6 figures.

Thermodynamics of Dipolar Chain Systems

The thermodynamics of a quantum system of layers containing perpendicularly oriented dipolar molecules is studied within an oscillator approximation for both bosonic and fermionic species. The system is assumed to be built from chains with one molecule in each layer. We consider the effects of the intralayer repulsion and quantum statistical requirements in systems with more than one chain. Specifically, we consider the case of two chains and solve the problem analytically within the harmonic Hamiltonian approach which is accurate for large dipole moments. The case of three chains is calculated numerically. Our findings indicate that thermodynamic observables, such as the heat capacity, can be used to probe the signatures of the intralayer interaction between chains. This should be relevant for near future experiments on polar molecules with strong dipole moments.Comment: 15 pages, 5 figures, final versio

Thermal rates for baryon and anti-baryon production

We use a form of the fluctuation-dissipation theorem to derive formulas giving the rate of production of spin-1/2 baryons in terms of the fluctuations of either meson or quark fields. The most general formulas do not assume thermal or chemical equilibrium. When evaluated in a thermal ensemble we find equilibration times on the order of 10 fm/c near the critical temperature in QCD.Comment: 22 pages, 4 tables and 2 figures, REVTe
