Teaching to address diverse learning needs: development and validation of a Differentiated Instruction Scale     

Amélie Roy  Frédéric Guay  Pierre Valois 《International Journal of Inclusive Education》2013,17(11):1186-1204

In the province of Quebec, Canada, a trend towards full inclusion has impelled teachers to adapt their instruction to meet the needs of both advanced and weaker learners in regular school settings. The main purpose of the present investigation was to develop and validate the Differentiated Instruction Scale (DIS), which assesses the use of instructional adaptations and academic progress monitoring strategies in general education classrooms. A total of 125 elementary school teachers participated in a cross-sectional study, allowing us to develop and validate the DIS. Overall our results show that the DIS is composed of two factors that are consistent with the predicted constructs (instructional adaptations and academic progress monitoring). Evidence of convergent validity is provided through correlations among DIS' subscales and two criteria: (1) teachers' autonomy support and (2) perceptions of school climate. Results also reveal that teachers tend to use instructional adaptations that do not require much preparation or tailored instruction. The DIS could thus be used in future research to investigate outcomes of differentiated instruction. Moreover, it could provide useful information on optimal strategies for promoting learning in children with different abilities in general education classrooms.  相似文献   

New Challenges in Agricultural Advisory Services from a Research Perspective: A Literature Review,Synthesis and Research Agenda     

Guy Faure  Yann Desjeux  Pierre Gasselin 《The Journal of Agricultural Education and Extension》2013,19(5):461-492

Abstract

Purpose: Agricultural advisory services are perceived by many actors involved in rural development as a key driver behind innovation processes in agriculture. However, changes in national and global contexts cause dramatic changes in the orientation of advisory services, their organisation and their methods of intervention. This article aims to analyse the major research topics related to agricultural advice.

Design/methodology/approach: The study is based on an extensive review of literature produced over a ten-year period that is accessible through the CAB, ECONLIT and Web of Science citation indexes. Using keywords related to extension and advisory services, we selected published articles according to the relevance of the results provided in relation to advisory services and the quality of the discussion on past or current controversies.

Findings: The results show that the ongoing scientific debates are shaped by the diversity of disciplines, methods, topics and schools of thought. The scientific community largely has focussed on five main themes: (1) the institutional environment of agricultural advisory services; (2) the structures necessary for the operation of an advisory system; (3) the actors providing advisory services and the skills deployed in advisory activities; (4) the approaches, methods, tools and content of advisory activities; and (5) the assessment and impacts of advisory systems.

Practical implications: This literature review is useful for researchers and practitioners to better understand research results in the field of advisory services. It paves the way for future research.

Originality/Value: Although many articles have been written in recent decades on agricultural advisory services, few studies provide an overview of the contributions of, and debates in, the international scientific community.  相似文献   

From Practice to Theory and back to Practice: Reflexivity in Measurement and Evaluation for Evidence-based Policy Making in the Information Society     

Gianluca Misuraca  Cristiano Codagnone  Pierre Rossel 《Government Information Quarterly》2013

This article presents a comprehensive review of literature and practice on the measurement and evaluation of ICT impact in general and of selected public eServices (eGovernment, eHealth, and eInclusion), within the context of the Information Society paradigm. It calls for a sustained meta-level analysis, in which it is important to have a self-reflexive layer where we evaluate and measure how we evaluate and measure, and what the implications and the trade-offs are. The analysis justifies the call for reflexivity as a necessary step towards advancing our understanding of the impact of ICT within the Information Society domains observed. The article concludes presenting some possible ways of re-coupling the conceptual and technical dimensions of the measurement process and linking the production of measurement data more closely with impact evaluation causal models and hypotheses. It suggests that this could be achieved by refocusing on the micro level and stimulating a gradual micro-macro link through an intermediate (meso) level, which effects need to be described using different measurements and evaluation paradigms. In order to do so it is required to refine and test our theories and models to find out where it would be most feasible to scale up to the global (macro) level and to shape and inform the production of more valid measurement indicators for better informing evidence-based policy making in the Information Society.  相似文献   

Evolution of fat oxidation during exercise in obese pubertal boys: Clinical implications

Abstract

In this study, we examined fat oxidation rates during exercise in obese pubescent boys. Three groups of pubescent boys (16 pre-pubescent, Tanner's stage I; 16 pubescent, Tanner's stage III; and 14 post-pubescent, Tanner's stage V) performed a graded test on a leg cycle ergometer. The first step of the test was fixed at 30 W and power was gradually increased by 20 W every 3.5 min. Oxygen consumption ([Vdot]O₂) and carbon dioxide production ([Vdot]CO₂) were determined as the means of measurements during the last 30 s of each step, which allowed us to calculate fat oxidation rates versus exercise intensity. Between 20 and 50% of peak oxygen consumption ([Vdot]O_2peak), fat oxidation rate in relative values (mg · min^?1 · kg FFM^?1) decreased continuously with pubertal development. In the same way, the maximum rate of fat oxidation occurred at a lower percentage of [Vdot]O_2peak (pre-pubescent: 49.47 ± 1.62%; pubescent: 47.43 ± 1.26%; post-pubescent: 45.00 ± 0.97%). Our results confirm that puberty is responsible for a decrease in fat free mass capacities to use fat during exercise. The results suggest that post-pubescent obese boys need to practise physical activity at a lower intensity than pre-pubescent boys to enhance lipolysis and diminish adipose tissue and the consequences of obesity.  相似文献   

ENTRE REPRODUCTION ET MOBILISATION: LES RAPPORTS DE GENRE EN FORMATION CONTINUE EN FRANCE ET AU CANADA     

Christine Fourner  Pierre Béret  Pierre Doray  Paul Bélanger 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》2009,55(1):75-103

REPRODUCTION OR MOBILISATION? GENDER PROPORTIONS IN CONTINUING EDUCATION IN FRANCE AND CANADA – Initial education provisions for women have evolved greatly over the past 40 years. But what about their situation within adult education and training? This article, comparing Canada and France, shows that, while it is well known that more women than men participate in adult education, their greater presence in professional training courses is a new development. The analysis highlights certain particular findings, such as the growing demand for continuing education in Canada and the increased rate of participation by full-time employees in France. In both countries, a number of social factors continue to influence women’s participation.  相似文献   

Biomechanical analysis of the “waiter’s serve” on upper limb loads in young elite tennis players     

Pierre Touzard  Richard Kulpa  Benoit Bideau  Bernard Montalvan  Caroline Martin 《European Journal of Sport Science》2019,19(6):765-773

Waiter’s serve (WS) is a specific tennis serve posture frequently observed in young players, and commonly considered as a technical error by tennis coaches. However, biomechanical impact of WS is unknown. The aims of this study were to identify the potential consequences of WS in young elite players relating to performance and injury risk, and to explain the kinematic causes of WS. Serve of 18 male junior elite players (Top 10 national French ranking, aged 12–15 years) was captured with a 20 camera, 200?Hz VICON MX motion analysis system. Depending on their serve technique, the players were divided into two groups (WS versus Normal Serve [NS]) by experienced coaches. Injury data were collected for each player during a 12-month-period following the motion capture. Normalized peak kinetic values of the dominant arm were calculated using inverse dynamics. In order to explain WS posture, upper limb kinematics were calculated during the cocking and the acceleration phases of the serve.
