Using IT Support to improve the quality of Peer Assisted Learning

Peer assisted learning (PAL) is one way to increase the empowerment of students through their learning practices and, hence, enhance their learning journey. PAL involves students mentoring groups of academically less experienced students; develops the quality and diversity of student learning, and enables students to become active partners in their learning experience. PAL supports student transition into higher education and there is evidence that it can aid retention in the early weeks of degree study. Retention is becoming a key issue for universities and one of the key performance indicators (KPIs) of quality education under the strategy for higher education set out by the current government. The PAL³ project is funded by Learn Higher and is an on going project investigating the use of IT support to improve the quality of Peer Assisted Learning. The project has set up a learning environment for students, and a knowledge base for PAL student mentors and PAL and other academic staff. This paper reports on initial findings from the project which can be divided into two strands. Firstly, the compilation of a staff knowledge base has highlighted the fact that PAL is known by different names and has different meanings in different places. We provide an initial classification. Secondly, the PAL student environment, which has been implemented and used by the student cohort and their PAL student mentors, has highlighted issues that were not envisaged at the beginning of the study and this has implications for future work

An Unfinished Canvas: Allocating Funding and Instructional Time for Elementary Arts Education

An Unfinished Canvas found that California's elementary schools face unique challenges inproviding all students with sequential, standards-based arts education. In particular, elementary principals identified inadequate funding and insufficient instructional time as significant barriers to the provision of arts education. For this study, we sought to further understand the impact of funding and time on elementary arts education. To do so, we examined the allocation of funding and instructional time in 10 schools across five states (Kentucky, Massachusetts, Minnesota, New Jersey, and California)

Blended Feedback II: Video feedback for individual students is the norm, on an undergraduate computer programming unit

The use of video feedback is popular, even usual, in fields involving social behaviour and interaction or physical performance. In other academic subject areas, the use of video as feedback is, as yet, uncommon. The work of others in this field covers group work, generic feedback, small numbers of students, samples and trials. We believe this may be one of the first studies on returning individual personalised feedback to a sizeable number of first year undergraduate students taking Computer Programming, or any other academic subject, for every assessment submitted on the unit. Student engagement with feedback is often lacking and in that case, a valuable learning opportunity is missed. Previous work using audio as feedback showed 80% of students would prefer audio to written feedback. However, the separation of submitted programming code from audio comments still limits ease of reference to the work. The next natural step was to use video screen capture to augment the student experience by improving easy reference to work by simultaneously providing contextually relevant narrative and visually referring to elements of the work

Fast pyrolysis of glucose‐based carbohydrates with added NaCl part 2: Validation and evaluation of the mechanistic model

A mechanistic model considering the significant catalytic effects of Na+ on fast pyrolysis of glucose‐based carbohydrates was developed in Part 1 of this study. A computational framework based on continuous distribution kinetics and mass action kinetics was constructed to solve the mechanistic model. Agreement between model yields of various pyrolysis products with experimental data from fast pyrolysis of glucose‐based carbohydrates dosed with NaCl ranging from 0–0.34 mmol/g at 500 °C validated the model and demonstrated the robustness and extendibility of the mechanistic model. The model was able to capture the yields of major and minor products as well as their trends across NaCl concentrations. Modeling results showed that Na+ accelerated the rate of decomposition and reduced the time for complete thermoconversion of carbohydrates. The sharp reduction in the yield of levoglucosan (LVG) from fast pyrolysis of cellulose in the presence of NaCl was mainly caused by reduced decomposition of cellulose chains via end‐chain initiation and depropagation due to Na+ favoring competing dehydration reactions. Analysis of the contributions of reaction pathways showed that the decomposition of LVG made a minor contribution to its yield reduction and contributed less than 0.5% to the final yield of glycolaldehyde from fast pyrolysis of glucose‐based carbohydrates in the presence of NaCl

Fast pyrolysis of glucose‐based carbohydrates with added NaCl part 1: Experiments and development of a mechanistic model

Sodium ions, one of the natural inorganic constituents in lignocellulosic biomass, significantly alter pyrolysis behavior and resulting chemical speciation. Here, experiments were conducted using a micropyrolyzer to investigate the catalytic effects of NaCl on fast pyrolysis of glucose‐based carbohydrates (glucose, cellobiose, maltohexaose, and cellulose), and on a major product of cellulose pyrolysis, levoglucosan (LVG). A mechanistic model that addressed the significant catalytic effects of NaCl on the product distribution was developed. The model incorporated interactions of Na+ with cellulosic chains and low molecular weight species, reactions mediated by Na+ including dehydration, cyclic/Grob fragmentation, ring‐opening/closing, isomerization, and char formation, and a degradation network of LVG in the presence of Na+. Rate coefficients of elementary steps were specified based on Arrhenius parameters. The mechanistic model for cellulose included 768 reactions of 222 species, which included 252 reactions of 150 species comprising the mechanistic model of glucose decomposition in the presence of NaCl

Applying Innovative Technologies and Practices in the Rapid Shift to Remote Learning

Shifting to remote learning during times of a crisis, such as the COVID-19 pandemic, is very different from well-planned online learning. This paper highlights the experience of shifting to remote learning and outlines lessons learned from the experience. The COVID-19 pandemic brought a wholly new educational context, which uncovered problems such as; course delivery & assessment; communication & misinformation; and technology limitations. This highlights a gap in research on rapid mid-term shift to remote learning in times of a crisis. There are plenty of resources for Information Systems education to draw lessons for effective online learning practices. However, there is limited research on remote learning in response to a crisis, such as COVID-19. This paper presents a case study at Bournemouth University, in which a Business Systems Analysis and Design (BSAD) course was moved to remote learning during COVID-19. The results reflect on the importance of learning focus, students focus, and learning resource focus for remote learning. This includes activities to promote effective communication and information resources, student engagement and support, and remote course delivery and assessment. All these activities are essential elements in a rapid shift from blended learning to remote learning during a crisis, such as COVID-19

Clinical and serological features of systemic sclerosis in a multicenter African American cohort: Analysis of the genome research in African American scleroderma patients clinical database.

Racial differences exist in the severity of systemic sclerosis (SSc). To enhance our knowledge about SSc in African Americans, we established a comprehensive clinical database from the largest multicenter cohort of African American SSc patients assembled to date (the Genome Research in African American Scleroderma Patients (GRASP) cohort).African American SSc patients were enrolled retrospectively and prospectively over a 30-year period (1987-2016), from 18 academic centers throughout the United States. The cross-sectional prevalence of sociodemographic, clinical, and serological features was evaluated. Factors associated with clinically significant manifestations of SSc were assessed using multivariate logistic regression analyses.The study population included a total of 1009 African American SSc patients, comprised of 84% women. In total, 945 (94%) patients met the 2013 American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) classification criteria for SSc, with the remaining 64 (6%) meeting the 1980 ACR or CREST (calcinosis, Raynaud's phenomenon, esophageal dysmotility, sclerodactyly, telangiectasia) criteria. While 43% were actively employed, 33% required disability support. The majority (57%) had the more severe diffuse subtype and a young age at symptom onset (39.1 ± 13.7 years), in marked contrast to that reported in cohorts of predominantly European ancestry. Also, 1 in 10 patients had a severe Medsger cardiac score of 4. Pulmonary fibrosis evident on computed tomography (CT) chest was present in 43% of patients and was significantly associated with anti-topoisomerase I positivity. 38% of patients with CT evidence of pulmonary fibrosis had a severe restrictive ventilator defect, forced vital capacity (FVC) ≤50% predicted. A significant association was noted between longer disease duration and higher odds of pulmonary hypertension, telangiectasia, and calcinosis. The prevalence of potentially fatal scleroderma renal crisis was 7%, 3.5 times higher than the 2% prevalence reported in the European League Against Rheumatism Scleroderma Trials and Research (EUSTAR) cohort.Our study emphasizes the unique and severe disease burden of SSc in African Americans compared to those of European ancestry

Electronic health records in ambulances: the ERA multiple-methods study

Background: Ambulance services have a vital role in the shift towards the delivery of health care outside hospitals, when this is better for patients, by offering alternatives to transfer to the emergency department. The introduction of information technology in ambulance services to electronically capture, interpret, store and transfer patient data can support out-of-hospital care. Objective: We aimed to understand how electronic health records can be most effectively implemented in a pre-hospital context in order to support a safe and effective shift from acute to community-based care, and how their potential benefits can be maximised. Design and setting: We carried out a study using multiple methods and with four work packages: (1) a rapid literature review; (2) a telephone survey of all 13 freestanding UK ambulance services; (3) detailed case studies examining electronic health record use through qualitative methods and analysis of routine data in four selected sites consisting of UK ambulance services and their associated health economies; and (4) a knowledge-sharing workshop. Results: We found limited literature on electronic health records. Only half of the UK ambulance services had electronic health records in use at the time of data collection, with considerable variation in hardware and software and some reversion to use of paper records as services transitioned between systems. The case studies found that the ambulance services’ electronic health records were in a state of change. Not all patient contacts resulted in the generation of electronic health records. Ambulance clinicians were dealing with partial or unclear information, which may not fit comfortably with the electronic health records. Ambulance clinicians continued to use indirect data input approaches (such as first writing on a glove) even when using electronic health records. The primary function of electronic health records in all services seemed to be as a store for patient data. There was, as yet, limited evidence of electronic health records’ full potential being realised to transfer information, support decision-making or change patient care. Limitations: Limitations included the difficulty of obtaining sets of matching routine data for analysis, difficulties of attributing any change in practice to electronic health records within a complex system and the rapidly changing environment, which means that some of our observations may no longer reflect reality. Conclusions: Realising all the benefits of electronic health records requires engagement with other parts of the local health economy and dealing with variations between providers and the challenges of interoperability. Clinicians and data managers, and those working in different parts of the health economy, are likely to want very different things from a data set and need to be presented with only the information that they need
