Giving students an eDGE: Focusing on ePortfolios for Graduate Employability

Universities are placing increased attention on providing students with ePortfolios and online teaching platforms to enhance learning and employability. The aim of this paper is to investigate the views of dietetic students on the usefulness of PebblePad as a learning platform and ePortfolio tool for evidencing graduate competency and enhancing employability. This research was conducted within a multi-component design-based research framework. PebblePad was introduced to the [blinded] Bachelor of Nutrition and Dietetics four-year degree in 2016. Students in years 1 and 3 enrolled in courses utilising PebblePad in 2016 and 2017 were invited to complete an online survey at the conclusion of each course. Surveys were completed by 116 students (2016 n=50; 2017 n=66). Students perceived that PebblePad could impact on their employability through supporting their learning as well as assisting their understanding and competency development as a professional. This was more evident in Year 3 students than Year 1. The aspects of PebblePad perceived as most beneficial for employability were the ability to: 1) collate experiences and assessment; 2) evidence dietetic competencies via ‘tagging’; and 3) facilitate reflection. The least beneficial aspects were: 1) usability and navigation of PebblePad; 2) lack of clarity around using PebblePad to evidence employability; and 3) belief that required reflections were excessive. ePortfolios and learning platforms such as PebblePad are perceived by students to be useful for evidencing employability, with potential improvements in assessment design further enhancing their use

Developing measures of immersion and motivation for learning technologies in healthcare simulation: a pilot study

Introduction: Medical education has benefitted from the introduction of new technology within recent years. Immersivedevices, such as, 360-degree films and virtual reality have become new ways of simulating clinical experiences. The aim of the study was to validate and test reliability of a new measure of engagement.Methods: A between-participants design of 2 groups viewing a clinical consultation on a 360-degree headset or 2D monitor was conducted following computer random allocation of 40 healthcare professionals recruited from scheduled teaching. Twenty-three were assigned to 360-degree and 17 to 2D Medias. Adapted Immersion Experience Questionnaire (AIEQ) and Abridged Intrinsic Motivation Inventory (AIMI) were modified to match factors relating to clinical encounters. AIEQ and AIMI were utilised as the data collection tool by each group following video viewing. Spearman’s rank correlation was used to assess relationship between immersion and motivation. Comparisons between 360-degree and 2D media responses were made using Wilcoxon’s signed ranks test. Internal reliability coefficients of adapted measures were calculated with Cronbach alpha scores. Results: Total immersion scores were statistically higher in those experiencing 360 (P<0.05), with a median difference of 14.50 (95% CI 6.50-22.00). A positive correlation existed between the total AIEQ and total score of the AIMI in both groups (rs=0.88, n=17, P<0.001). Internal consistency and reliability was demonstrated with a high Cronbach alpha score for the AIEQ (α=0.91). AIMI subscale alpha value was also high at (α=0.95) which shows the measures to be of high internal reliability.Conclusions: Adaptation and validation of existing measures for use in healthcare education can be used to quantify levels of immersion and motivation. Standardising measures for use in evaluating new Technology Enhanced Learning is a step to aid understanding on how we develop these tools in medical education and how we might learn from immersive technology

Herschel Extreme Lensing Line Observations: Dynamics of two strongly lensed star forming galaxies near redshift z = 2

We report on two regularly rotating galaxies at redshift z=2, using high resolution spectra of the bright [CII] 158 micron emission line from the HIFI instrument on the Herschel Space Observatory. Both SDSS090122.37+181432.3 ("S0901") and SDSS J120602.09+514229.5 ("the Clone") are strongly lensed and show the double-horned line profile that is typical of rotating gas disks. Using a parametric disk model to fit the emission line profiles, we find that S0901 has a rotation speed v sin(i) = 120 +/- 7 km/s and gas velocity dispersion sigma < 23 km/s. The best fitting model for the Clone is a rotationally supported disk having v sin(i) = 79 +/- 11 km/s and sigma < 4km/s. However the Clone is also consistent with a family of dispersion-dominated models having sigma = 92 +/- 20 km/s. Our results showcase the potential of the [CII] line as a kinematic probe of high redshift galaxy dynamics: [CII] is bright; accessible to heterodyne receivers with exquisite velocity resolution; and traces dense star-forming interstellar gas. Future [CII] line observations with ALMA would offer the further advantage of spatial resolution, allowing a clearer separation between rotation and velocity dispersion.Comment: 20 pages, 4 figures; in press at The Astrophysical Journa

Organic contaminant content and physico-chemical characteristics of waste materials recycled in agriculture

A range of wastes representative of materials currently applied, or with future potential to be applied, to agricultural land in the UK as fertilisers and soil improvers or used as animal bedding in livestock production, were investigated. In addition to full physico-chemical characterization, the materials were analysed for a suite of priority organic contaminants. In general, contaminants were present at relatively low concentrations. For example, polychlorinated dibenzo-p-dioxins/dibenzofurans and polychlorinated biphenyls in biosolids and compost-like-outputs (CLOs) were, in most cases, between 5-50 times lower than proposed and implemented European limit values for biosolids or composts applied to agricultural land. However, the technical basis for these limits may need to be re-evaluated. Polybrominated, and mixed halogenated, dibenzo-p-dioxins/dibenzofurans are not currently considered in risk assessments of dioxins and dioxin-like chemicals, but were detected in the biosolids and compost-like-outputs and their potential contribution to the overall toxic equivalency will be assessed. Other, ‘emerging’ contaminants such as perfluoralkyl compounds (PFCs) and organophosphate flame retardants were detected in several of the waste materials, and their potential significance is discussed. The study is part of a wider research programme that will provide evidence to improve confidence in the use of waste-derived materials in agriculture and establish guidelines to protect the food chain where necessary
