    Through rigorous forms of research, including a randomised controlled trial, Quality Teaching Rounds (QTR) has been shown to make a positive difference to the quality of teaching, teacher morale and school culture. This presentation will draw on both quantitative and qualitative evidence to demonstrate the impact of QTR, outlining its effects across a range of NSW primary and secondary schools and for teachers at very different stages of their careers. The essential components of QTR will be elaborated with analysis of the underlying mechanisms that contribute to the effectiveness of this form of professional development in improving teaching practice. As a relatively low-cost, short-term intervention with applicability across all subjects, stages of learning and schooling sectors, the multi-faceted evidence provided has significant implications for teacher development policy and practice. Importantly, the approach is founded in respect for the capacities of the teaching workforce in Australia, which is in stark contrast to some initiatives, here and around the world, that emphasise accountability at the expense of teacher growth and wellbeing

    Exploring Quality Teaching in the Online Environment Using an Evidence-Based Approach

    Online learning is increasingly ubiquitous in higher education. However, research regarding online teaching often focuses on the affordances of the online environment rather than on the quality of pedagogy. In this paper we consider how online learning could be enhanced using rich pedagogical models that are consistent with a wealth of existing knowledge on pedagogy for face-to-face settings. To do so, we apply an established framework, the Quality Teaching model, to explore pedagogy in the online environment and illustrate its potential benefits using a case study of 60 students in a tertiary mathematics teacher education program. We conclude that the use of an evidence-based pedagogical model can help guide online instructors in the development of high quality online course

    Detecting and understanding non-compliance with conservation rules

    AbstractThis paper establishes the context for the special issue, “Detecting and Understanding Violations of Conservation Rules”. Illicit or non-compliant human behaviors may occur in all ecosystems and range from subsistence illegal resource collection to poaching by organized criminal syndicates. Such acts have an enormous impact on social–ecological systems, but monitoring non-compliance is challenging, primarily because the topic is sensitive and victims are voiceless. The future of many conservation areas depends upon compliance with conservation rules. However, with a growing human population, consumptive societies, and rapid expansion of business opportunities fueled by new technology, there is little doubt that demand will remain steady or increase for many of our natural resources. We outline major conservation compliance issues and impacts, and review models and methods used to monitor and respond to the problem for both subsistence and commercial non-compliance

    Identifying an opportunity to harness the strength of collaborating across departments, institutions, and libraries, librarians from the Education and Clinical Services, and Research and Scholarly Communication Services of Lamar Soutter Library (LSL), University of Massachusetts Medical School (UMMS), partnered with the librarian for the Hartford Medical Society Library at Lyman Maynard Stowe Library, UConn Health, to organize an exhibit of historical ophthalmology items at UMMS. The exhibit, “Eyes to the Past,” ran from the summer through the fall, 2019, and included textbooks from the 1800s, prints to test for color blindness, artifacts such as eye surgery kits, glass eyeballs, stereoscopes, and an early 20th century ophthalmoscope. A medical student with an interest in ophthalmology was recruited to research each item on display and provide text for identification cards. The exhibit proved an excellent bridge to form a partnership with the UMass Memorial Eye Center and the UMass Medical School Department of Ophthalmology and Visual Sciences. The Eye Center just welcomed its first class of residents in July, making the timing of the exhibit perfect for the LSL’s outreach efforts. A presentation and reception, co-hosted by the LSL and the Eye Center, proved the “eye-deal” culmination to this successful collaborative effort

    BACKGROUND: Cataract is the leading cause of blindness in the world, and cataract surgery is one of the most commonly performed operations in the Western world. Preferred surgical techniques have changed dramatically over the past half century with associated improvements in outcomes and safety. Femtosecond laser platforms that can accurately and reproducibly perform key steps in cataract surgery, including corneal incisions, capsulotomy and lens fragmentation, are now available. The potential advantages of laser-assisted surgery are broad, and include greater safety and better visual outcomes through greater precision and reproducibility. OBJECTIVES: To compare the effectiveness of laser-assisted cataract surgery with standard ultrasound phacoemulsification cataract surgery by gathering evidence on safety from randomised controlled trials (RCTs). SEARCH METHODS: We searched CENTRAL (which contains the Cochrane Eyes and Vision Trials Register) (2016, Issue 4), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE (January 1946 to May 2016), EMBASE (January 1980 to May 2016), Latin American and Caribbean Health Sciences Literature Database (LILACS) (January 1982 to May 2016), the ISRCTN registry (www.isrctn.com/editAdvancedSearch), ClinicalTrials.gov (www.clinicaltrials.gov), the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en) and the U.S. Food and Drugs Administration (FDA) website (www.fda.gov). We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 10 May 2016. SELECTION CRITERIA: We included randomised controlled trials where laser-assisted cataract surgery was compared to standard ultrasound phacoemulsification cataract surgery. We graded the certainty of the evidence using GRADE. DATA COLLECTION AND ANALYSIS: Two review authors independently screened the search results, assessed risk of bias and extracted data using the standard methodological procedures expected by Cochrane. The primary outcome for this review was intraoperative complications in the operated eye, namely anterior capsule and posterior capsule tears. The secondary outcomes were visual acuity (corrected distance visual acuity (CDVA) and uncorrected distance visual acuity (UDVA)), refractive outcomes, quality of vision (as measured by any validated visual function score), postoperative complications and cost-effectiveness. MAIN RESULTS: We included 16 RCTs conducted in Germary, Hungary, Italy, India, China and Brazil that enrolled a total of 1638 eyes of 1245 adult participants. Overall, the studies were at unclear or high risk of bias. In 11 of the studies the authors reported financial links with the manufacturer of the laser platform evaluated in their studies. Five of the studies were within-person (paired-eye) studies with one eye allocated to one procedure and the other eye allocated to the other procedure. These studies were reported ignoring the paired nature of the data.The number of anterior capsule and posterior capsule tears reported in the included studies for both laser cataract surgery and manual phacoemulsification cataract surgery were low. There were four anterior capsule tears and one posterior capsule tear in 1076 eyes reported in 10 studies (2 anterior capsule tears in laser arms, 2 anterior capsule tears and 1 posterior capsule tear in standard phacoemulsification arms). We are very uncertain as to the effect of laser-assisted surgery compared to standard phacoemulsification surgery with respect to these two outcomes. For postoperative cystoid macular oedema and elevated postoperative intraocular pressures, again the evidence was inconclusive (odds ratio (OR) 0.58, 95% confidence interval (CI) 0.20 to 1.68; 957 eyes, 9 studies, low certainty evidence; and OR 0.57, 95% CI 0.11 to 2.86; 903 eyes, 8 studies, low certainty evidence).We found little evidence of any important difference in postoperative visual acuity between laser-assisted and standard phacoemulsification arms. There was a small advantage for laser-assisted cataract surgery at six months in CDVA. However, the mean difference (MD) was -0.03 logMAR (95% CI -0.05 to -0.00; 224 eyes, 3 studies, low certainty evidence) which is equivalent to 1.5 logMAR letters and is therefore, clinically insignificant. No studies reported patient-reported outcome measures such as visual function.There were no data reported on costs or resource use but three studies reported the time taken to do the surgery. There was little evidence of any major difference between the two procedures in this respect (MD 0.1 minutes, 95% CI -0.02 to 0.21; 274 eyes, low certainty evidence). AUTHORS' CONCLUSIONS: The evidence from the 16 randomised controlled trials RCTs included in this review could not determine the equivalence or superiority of laser-assisted cataract surgery compared to standard manual phacoemulsification for our chosen outcomes due to the low to very low certainty of the evidence available from these studies. As complications occur rarely, large, adequately powered, well designed, independent RCTs comparing the safety and efficacy of laser-assisted cataract surgery with standard phacoemulsification cataract surgery are needed. Standardised reporting of complications and visual and refractive outcomes for cataract surgery would facilitate future synthesis. Data on patient-reported outcomes and cost-effectiveness are needed. Paired-eye studies should be analysed and reported appropriately

    Can continuing professional development utilizing a game-centered approach improve the quality of physical education teaching delivered by generalist primary school teachers?

    Get PDF
    The primary objective of this study was to evaluate the efficacy of a continuing professional development (CPD) intervention in producing changes in physical education (PE) teaching practice and PE teaching quality by generalist primary school teachers when the CPD addressed the use of a game-centred approach. A cluster randomized controlled trial was conducted in seven primary schools in the Hunter Region, New South Wales, Australia. One year six teacher from each school was randomized into the Professional Learning for Understanding Games Education (PLUNGE) intervention ( n = 4 teachers) or the 7-week wait-list control ( n = 3) condition. The PLUNGE intervention (weeks 1–5) used an instructional framework to improve teachers’ knowledge, understanding and delivery of a game-centred curriculum, and included an information session and weekly in-class mentoring. The intervention was designed to enhance content and pedagogical knowledge for the provision of pedagogy focused on a broad range of learning outcomes. Teaching quality was assessed at baseline and follow-up (weeks 6 and 7) via observation of two consecutive PE lessons using the Quality Teaching Lesson Observation Scales. Linear mixed models revealed significant group-by-time intervention effects ( p &lt; 0.05) for the quality of teaching (effect size: d = 1.7). CPD using an information session and mentoring, and a focus on the development of the quality of teaching using a game-centred pedagogical approach was efficacious in improving the quality of PE teaching among generalist primary school teachers. </jats:p

    Using Dynamic Contrast-Enhanced Magnetic Resonance Imaging Data to Constrain a Positron Emission Tomography Kinetic Model: Theory and Simulations

    Get PDF
    We show how dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) data can constrain a compartmental model for analyzing dynamic positron emission tomography (PET) data. We first develop the theory that enables the use of DCE-MRI data to separate whole tissue time activity curves (TACs) available from dynamic PET data into individual TACs associated with the blood space, the extravascular-extracellular space (EES), and the extravascular-intracellular space (EIS). Then we simulate whole tissue TACs over a range of physiologically relevant kinetic parameter values and show that using appropriate DCE-MRI data can separate the PET TAC into the three components with accuracy that is noise dependent. The simulations show that accurate blood, EES, and EIS TACs can be obtained as evidenced by concordance correlation coefficients >0.9 between the true and estimated TACs. Additionally, provided that the estimated DCE-MRI parameters are within 10% of their true values, the errors in the PET kinetic parameters are within approximately 20% of their true values. The parameters returned by this approach may provide new information on the transport of a tracer in a variety of dynamic PET studies

    An active learning approach to home heating in the smart grid

    Get PDF
    A key issue for the realization of the smart grid vision is the implementation of effective demand-side management. One possible approach involves exposing dynamic energy prices to end-users. In this paper, we consider a resulting problem on the user’s side: how to adaptively heat a home given dynamic prices. The user faces the challenge of having to react to dynamic prices in real time, trading off his comfort with the costs of heating his home to a certain temperature. We propose an active learning approach to adjust the home temperature in a semiautomatic way. Our algorithm learns the user’s preferences over time and automatically adjusts the temperature in real-time as prices change. In addition, the algorithm asks the user for feedback once a day. To find the best query time, the algorithm solves an optimal stopping problem. Via simulations, we show that our algorithm learns users’ preferences quickly, and that using the expected utility loss as the query criterion outperforms standard approaches from the active learning literature
