Electronic marking of statistics assessments for bioscience students

We describe the main features of a program written to perform electronic marking of quantitative or simple text questions. One of the main benefits is that it can check answers for being consistent with earlier errors, so can cope with a range of numerical questions. We summarise our experience of using it in a statistics course taught to 200 bioscience students

Obstacles to returning to work with chronic pain : in-depth interviews with people who are off work due to chronic pain and employers

Background: The global burden of chronic pain is growing with implications for both an ageing workforce and employers. Many obstacles are faced by people with chronic pain in finding employment and returning to work after a period of absence. Few studies have explored obstacles to return-to-work (RTW) from workers’ and employers’ perspectives. Here we explore views of both people in pain and employers about challenges to returning to work of people who are off work with chronic pain. Methods: We did individual semi-structured interviews with people who were off work (unemployed or off sick) with chronic pain recruited from National Health Service (NHS) pain services and employment services, and employers from small, medium, and large public or private sector organisations. We analysed data using the Framework method. Results: We interviewed 15 people off work with chronic pain and 10 employers. Obstacles to RTW for people with chronic pain spanned psychological, pain related, financial and economic, educational, and work-related domains. Employers were concerned about potential attitudinal obstacles, absence, ability of people with chronic pain to fulfil the job requirements, and the implications for workplace relationships. Views on disclosure of the pain condition were conflicting with more than half employers wanting early full disclosure and two-thirds of people with chronic pain declaring they would not disclose for fear of not getting a job or losing a job. Both employers and people with chronic pain thought that lack of confidence was an important obstacle. Changes to the job or work conditions (e.g. making reasonable adjustments, phased return, working from home or redeployment) were seen by both groups as facilitators. People with chronic pain wanted help in preparing to RTW, education for managers about pain and supportive working relationships. Conclusions: People with chronic pain and employers may think differently in terms of perceptions of obstacles to RTW. Views appeared disparate in relation to disclosure of pain and when this needs to occur. They appeared to have more in common regarding opinions about how to facilitate successful RTW. Increased understanding of both perspectives may be used to inform the development of improved RTW interventions

Understanding the Impact of Technology: Learner and School Level Factors

The first part of this report focuses on the factors impacting on learner performance in national tests at primary and secondary level. This was the central research question of this research. The second section focuses on teacher and learner perceptions of their own responses to learning and the learning environment. This was centred on, but not confined to, their school. The institutional structures record the level of development of the schools sampled here and investigate the use of two key technologies – interactive whiteboards and learning platform

The work of return to work. Challenges of returning to work when you have chronic pain : a meta-ethnography

Aims To understand obstacles to returning to work, as perceived by people with chronic non-malignant pain and as perceived by employers, and to develop a conceptual model. Design Synthesis of qualitative research using meta-ethnography. Data sources Eleven bibliographic databases from inception to April 2017 supplemented by citation tracking. Review methods We used the methods of meta-ethnography. We identified concepts and conceptual categories, and developed a conceptual model and line of argument. Results We included 41 studies. We identified three core categories in the conceptual model: managing pain, managing work relationships and making workplace adjustments. All were influenced by societal expectations in relation to work, self (self-belief, self-efficacy, legitimacy, autonomy and the meaning of work for the individual), health/illness/pain representations, prereturn to work support and rehabilitation, and system factors (healthcare, workplace and social security). A mismatch of expectations between the individual with pain and the workplace contributed to a feeling of being judged and difficulties asking for help. The ability to navigate obstacles and negotiate change underpinned mastering return to work despite the pain. Where this ability was not apparent, there could be a downward spiral resulting in not working. Conclusions For people with chronic pain, and for their employers, navigating obstacles to return to work entails balancing the needs of (1) the person with chronic pain, (2) work colleagues and (3) the employing organisation. Managing pain, managing work relationships and making workplace adjustments appear to be central, but not straightforward, and require substantial effort to culminate in a successful return to work

An LED Approach for Measuring the Photocatalytic Breakdown of Crystal Violet Dye

A simple technique to assess the reactivity of photocatalytic coatings sprayed onto transmissive glass surfaces was developed. This new method uses ultraviolet (UV) gallium nitride (GaN) light-emitting diodes (LEDs) to drive a photocatalytic reaction (the photocatalytic breakdown of a UV-resistant dye applied to a surface coated with the semiconductor titanium dioxide); and then a combination of a stabilized white light LED and a spectrometer to track the dye degradation as a function of time. Simple, standardized evaluation techniques that assess photocatalytic materials over a variety of environmental conditions, including illumination level, are not generally available and are greatly needed prior to in situ application of photocatalytic technologies. To date, much research pertaining to this aspect of photocatalysis has been limited and has focused primarily on laboratory experiments using mercury lamps. Mercury lamp illumination levels are difficult to control over large ranges and are temporally modulated by line power, limiting their use in helping to understand and predict how photocatalytic materials will behave in natural environmental settings and conditions. The methodology described here, using steady-state LEDs and time series spectroradiometric techniques, is a novel approach to explore the effect of UV light on the photocatalytic degradation of a UV resistant dye (crystal violet). GaN UV LED arrays, centered around 365 nm with an adjustable DC power supply, are used to create a small, spatially uniform light field where the steady state light level can be varied over three to four orders of magnitude. For this study, a set of glass microscope slides was custom coated with a thinly sprayed layer of photocatalytic titanium dioxide. Crystal violet was then applied to these titanium-dioxide coated slides and to uncoated control slides. The slides were then illuminated at various light levels from the dye side of the slide by the UV LED array. To monitor dye degradation on the slides over time, a temperature-stabilized white light LED was used to illuminate the opposite side of the slides. As the dye degraded, the amount of light from the white light LED transmitted through the slide was monitored with a spectrometer and subsequently analyzed to determine and compare the rate of dye degradation for photocatalytically coated versus uncoated slide surfaces. The long-term stability of the spectrometer/white light LED combination, which required only a single reference spectra to be taken for a time series sequence of several hours, enabled accurate measurements of transmitted light over time. Time series transmission curves were generated and results demonstrated that over time the transmission increased much more rapidly on the coated slides than on the control slides. This experimental configuration and methodology for photocatalytic activity measurement minimizes many external variable effects and allows low light level studies to be performed. This study also compares the advantages of this novel LED light source design to traditional mercury lamp systems and non-LED lamp approaches that have conventionally been used. The methodology and experimental design research summarized in this abstract is partly funded by the Department of Homeland Security, Science and Technology Directorate, and by the NASA Stennis Space Center Innovative Partnerships Program

Personalising Learning

This report presents the findings of the Personalising Learning project, which was commissioned by Becta. The core aim of the project is to develop a robust model of the effective use of digital technologies for the personalising of learning. Personalising learning in this context involves the tailoring of pedagogy, curriculum and learning support to meet the needs and aspirations of individual learners irrespective of ability, culture or social status in order to nurture the unique talents of every pupil. Section 2 of this report outlines the background and aims of this research project. Section 3 traces the development of the model and the accompanying learning equation. The key concept encapsulated in this model is that of overlapping action spaces, school, teaching, personal and living spaces, in which learning occurs. These spaces are populated by the key educational stakeholders: learners, their teachers, their family and peers. In each of these spaces a range of digital technologies is available to support the learner. Section 4 is a validation of the model using evidence from field research
