The aim of this study was to examine the effectiveness of either a standard care programme (n = 9) or a 12-week supported exercise programme (n = 10) on glycaemic control, β-cell responsiveness, insulin resistance, and lipid profiles in newly diagnosed Type 2 diabetes patients. The standard care programme consisted of advice to exercise at moderate to high intensity for 30 min five times a week; the supported exercise programme consisted of three 60-min supported plus two unsupported exercise sessions per week. Between-group analyses demonstrated a difference for changes in low-density lipoprotein cholesterol only (standard care programme 0.01 mmol · L(-1), supported exercise programme -0.6 mmol · L(-1); P = 0.04). Following the standard care programme, within-group analyses demonstrated a significant reduction in waist circumference, whereas following the supported exercise programme there were reductions in glycosylated haemoglobin (6.4 vs. 6.0%; P = 0.007), waist circumference (101.4 vs. 97.2 cm; P = 0.021), body mass (91.7 vs. 87.9 kg; P = 0.007), body mass index (30.0 vs. 28.7 kg · m(-2); P = 0.006), total cholesterol (5.3 vs. 4.6 mmol · L(-1); P = 0.046), low-density lipoprotein cholesterol (3.2 vs. 2.6 mmol · L(-1); P = 0.028), fasting β-cell responsiveness (11.5 × 10(-9) vs. 7.0 × 10(-9) pmol · kg(-1) · min(-1); P = 0.009), and insulin resistance (3.0 vs. 2.1; P = 0.049). The supported exercise programme improved glycaemic control through enhanced β-cell function associated with decreased insulin resistance and improved lipid profile. This research highlights the need for research into unsupported and supported exercise programmes to establish more comprehensive lifestyle advice for Type 2 diabetes patients.  相似文献   

Exploring Interactive Writing as an Effective Practice for Increasing Head Start Students’ Alphabet Knowledge Skills     

Anna H. Hall  Michael D. Toland  Jennifer Grisham-Brown  Steve Graham 《Early Childhood Education Journal》2014,42(6):423-430

The current study used a pretest–posttest randomized control group design with 73 Head Start students, ages 3–5 years. The researcher served as the interactive writing teacher for the treatment group, rotating to five different classrooms in one Head Start center 3–4 days a week for 13 weeks. Children in the treatment group received a 10–15 min interactive writing lesson each day in small groups within their own classroom settings. Children in the control group received standard literacy instruction in small groups with their own classroom teachers. Child outcome data on upper case, lower case, and letter sound identification were collected before and after the intervention for both groups. Based on the large frequency of zeros on outcomes, zero-inflated Poisson regression analyses were performed. The results of the study showed that children receiving interactive writing identified more lower case and upper case letters at the end of the study relative to children in the control, but no differences were observed on letter sounds. While continued evaluation of the interactive writing strategy is needed in the preschool setting, the evidence from the current study shows encouraging trends in alphabet knowledge skill development as a result of this strategy.  相似文献   

Differences in Brain Activation Between Novices and Experts in Science During a Task Involving a Common Misconception in Electricity     

Steve Masson  Patrice Potvin  Martin Riopel  Lorie‐Marlène Brault Foisy 《Mind, Brain, and Education》2014,8(1):44-55

Science education studies have revealed that students often have misconceptions about how nature works, but what happens to misconceptions after a conceptual change remains poorly understood. Are misconceptions rejected and replaced by scientific conceptions, or are they still present in students' minds, coexisting with newly acquired scientific conceptions? In this study, we use functional magnetic resonance imaging (fMRI) to compare brain activation between novices and experts in science when they evaluate the correctness of simple electric circuits. Results show that experts, more than novices, activate brain areas involved in inhibition when they evaluate electric circuits in which a bulb lights up, even though there is only one wire connecting it to the battery. These findings suggest that experts may still have a misconception encoded in the neural networks of their brains that must be inhibited in order to answer scientifically.  相似文献   

Forming an effective partnership with a dedicated LabAssistant: A software shell for engineering laboratory exercises     

Steve Rothberg  Fiona Lamb 《European Journal of Engineering Education》2002,27(2):181-193

This paper describes the structure and use of LabAssistant, a software shell purposely written to run alongside engineering laboratory exercises and provide support to students undertaking the exercises. The structure of LabAssistant enables tutors to deliver their own laboratory sessions within the shell using only basic spreadsheet skills. LabAssistant is intended to be used in conjunction with in-depth, analytical laboratory exercises and its features include text entry, numerical input and checking (including verification of calculated values and provision of appropriate feedback), graph sketching, data plotting and report generation. Feedback from students confirms that LabAssistant has enhanced the learning experience, encouraging active engagement, building confidence and assisting progression through the exercise, even using the data and information input during the session to generate the majority of their laboratory write-up automatically. From the tutor's perspective, the provision of immediate and continual help to the students is a significant enhancement to the quality of the learning experience. LabAssistant complements the tutor who is now able to deal effectively with deeper conceptual difficulties and larger student numbers. The facility to verify all calculated values and the creation of a report in a standard electronic format are significant aids to the marking of student submissions.  相似文献   

‘… do that and I'll raise your grade’. Innovative module design and recursive feedback     

Steve Prowse  Julie Hughes  Deirdre Burke 《Teaching in Higher Education》2013,18(4):437-445

In an attempt to ensure students had a positive experience in their first semester, and to encourage future effective use of tutors’ feedback comments, a post-1992 university used a module in the school of education to develop an innovative feedback process. The process involved four stages: a first submission of written work, written feedback on that work, viva on student understanding of feedback, and final submission of written work. Between the viva and final submission, students could choose to improve their work for a specified number of grade points. The innovation was met favourably by students, and overall grades were improved against the previous iteration of the module. The project showed promise for adaptation in other forms for use across the University, though some ideological issues around assessment remain unresolved. The matter of the innovation and institutional quality standards is discussed in detail.  相似文献   

Teacher job satisfaction: lessons from the TSW Pathfinder Project     

Graham Butt  Ann Lance  Antony Fielding  Helen Gunter  Steve Rayner  Hywel Thomas 《School Leadership & Management》2013,33(5):455-471

Government policy assumes that modernization and remodelling will be effective as external intervention mechanisms to improve job satisfaction. Based on data collected as part of the evaluation of the ‘Transforming the School Workforce Pathfinder Project’, an argument is presented here which suggests that internal management models may be more effective in improving teacher job satisfaction. By comparing the responses of teachers within primary and special schools with those from secondary schools, internal factors are identified which may be more relevant than externally imposed measures.  相似文献   

Content and Context of the Administrative Internship: How Mentoring and Sustained Activities Impact Preparation     

Jennifer K. Clayton  Steve Myran 《Mentoring & Tutoring: Partnership in Learning》2013,21(1):59-75

As universities prepare educational leaders for twenty-first century schools, the quality and authenticity of the internship experience require both the strengths of university faculty and the expertise of practitioners to create authentic experiences that seek to bridge the theory-to-practice divide. One mechanism to achieve this is through quality mentorship by school- and central-office-based personnel during the internship experience. A central aspect of this professional relationship is the ability for the mentor to provide access to quality activities that will prepare the aspiring leader for his/her first administrative position. This exploratory study examined language utilized by interns in their time logs as well as information gleaned from preliminary surveys of both interns and mentors upon completion of their experience. Findings revealed the complexity of language analysis and revealed a need for understanding activities of interns and interactions with mentors in a contextual fashion.  相似文献   

Leadership and The Effective School   总被引：3，自引：3，他引：0  

Steve Murgatroyd  H.L. Gray 《School Leadership & Management》2013,33(3):285-295

The article examines the origins and purposes of assessment for learning (AfL) within the National Curriculum Assessment context in England. As a part of the Primary Strategy, AfL became part of the government's drive to improve standards through measuring school outcomes. The authors describe their investigation into teachers' understandings of AfL, how AfL has influenced teaching, learning and assessment in the intervening six years and whether it has established a presence as part of teaching pedagogy.  相似文献   

Tackling the remaining attainment gap between students with and without immigrant background: an investigation into the equivalence of SES constructs     

Jenny Lenkeit  Daniel H. Caro  Steve Strand 《Educational Research and Evaluation》2013,19(1):60-83

In England, students with immigrant background exhibit lower educational attainment than those without immigrant background. Family socioeconomic status (SES) helps explain differences in educational attainment, but a gap remains that differs in size for students with different immigrant backgrounds. While the explanatory repertoire for the remaining gap is broad, it has been neglected to comprehensively investigate whether family SES constructs are equivalent across students with different immigrant backgrounds. Using data from the first wave of the Children of Immigrants Longitudinal Survey in Four European Countries (CILS4EU) for England (n = 4,315), the paper applies exploratory structural equation modelling (ESEM) to evaluate measurement invariance of family background constructs across students without and with immigrant background, specifically Pakistani/Bangladeshi immigrant background. Results suggest differences in the structure of family SES indicators across groups and in their association with educational attainment. Complementary variables are suggested to enhance family SES indicators. Findings are relevant to researchers investigating educational inequalities related to immigrant background.  相似文献   

Perspectives on continuing professional development in and through information and communications technology     

Steve Kennewell 《Technology, Pedagogy and Education》2013,22(1):1-3

This paper considers the role and development of meaningful dialogue in digitally mediated learning (DML) in UK higher education for teachers. It argues that more research is vital in the field of meaningful dialogue if we are to avoid the risk that pedagogic values in DML become increasingly driven by market forces toward ‘data vending’ without sufficient contextualisation of learning as social practice. Three data collection sources are interpreted. The first is the narrativised experiences of a DML development team transforming an MA Education award; the second is some key reflections on the experiences of MA participants on a newly transformed DML module and the third is a brief analysis of student results and evaluations. The key focus for the paper is how important and challenging it can be to nurture a dialogic academic community online that clearly supports and nurtures the professional development of teachers across the education sector. Using a methodological approach incorporating Ulrich’s notion of ‘reflective competence’, the paper considers the pitfalls of transforming face-to-face modules into DML, arguing that both staff and participant preparation for DML must be at the forefront of such transformations. The paper concludes with a consideration of the vital role in DML of pedagogies which promote emotional engagement and ‘kindness’.  相似文献
