There is an increasing interest in linking character education programs with social and academic outcomes. The Child Development Project (CDP) is a character education program that promotes academic and social growth in teachers and students. This theory-driven evaluation employed a quasi-experimental design with matched control schools. School personnel participated in an intensive professional development process to learn the CDP model. Performance measures included state-mandated achievement measures, teacher self-assessment reports, and student attitudes and outcomes. Results yielded support for the CDP model as a strategy to improve social and, if properly implemented, cognitive outcomes in students; the model also improved teacher self-assessment and provided information that may facilitate professional growth about school collegiality. Implications for policy and practice will be discussed.  相似文献

Optimal sampling frequency in recording of resistance training exercises     

Paolo Bardella  Irene Carrasquilla García  Marco Pozzo  Julio Tous-Fajardo  Eduardo Saez de Villareal 《Sports biomechanics / International Society of Biomechanics in Sports》2017,16(1):102-114

The purpose of this study was to analyse the raw lifting speed collected during four different resistance training exercises to assess the optimal sampling frequency. Eight physically active participants performed sets of Squat Jumps, Countermovement Jumps, Squats and Bench Presses at a maximal lifting speed. A linear encoder was used to measure the instantaneous speed at a 200 Hz sampling rate. Subsequently, the power spectrum of the signal was computed by evaluating its Discrete Fourier Transform. The sampling frequency needed to reconstruct the signals with an error of less than 0.1% was f_99.9 = 11.615 ± 2.680 Hz for the exercise exhibiting the largest bandwidth, with the absolute highest individual value being 17.467 Hz. There was no difference between sets in any of the exercises. Using the closest integer sampling frequency value (25 Hz) yielded a reconstruction of the signal up to 99.975 ± 0.025% of its total in the worst case. In conclusion, a sampling rate of 25 Hz or above is more than adequate to record raw speed data and compute power during resistance training exercises, even under the most extreme circumstances during explosive exercises. Higher sampling frequencies provide no increase in the recording precision and may instead have adverse effects on the overall data quality.  相似文献   

On the role of cultural participation in tourism destination performance: an assessment using robust conditional efficiency approach     

Calogero Guccio  Domenico Lisi  Marco Martorana  Anna Mignosa 《Journal of Cultural Economics》2017,41(2):129-154

The relationship between culture and tourism has been widely investigated from different perspectives. A large strand of literature studies the role of cultural heritage to attract tourists, while a rich bulk of studies on cultural participation investigates the impact of tourism flows on the demand for culture. Another aspect worth investigating relates to the link between cultural participation and the performance of tourism destinations (TDs), as a higher cultural participation in an area could boost the performance in the management of tourism resources. However, so far, this issue has been disregarded in the literature, and this paper aims at filling this gap. Specifically, it studies the effect of cultural participation on TDs’ performance using a conditional efficiency approach that ensures robust inference on the role of environmental factors. We employ data on the Italian regions for the period 2004–2010, and we explore the role of cultural participation for tourism by using several indicators. Our findings offer empirical support to the positive role of cultural participation and, thus, suggest that public cultural policies might also boost the efficiency of the tourism sector.  相似文献

The objective of the present study was to investigate the effects of combined training without caloric restriction on inflammatory markers in overweight girls. Thirty-three girls (13–17 years) were assigned into overweight training (n = 17) or overweight control (n = 16) groups. Additionally, a normal-weight group (n = 15) was used as control for the baseline values. The combined training programme consisted of six resistance exercises (three sets of 6–10 repetitions at 60–70% 1 RM) followed by 30 min of aerobic exercise (walking/running) at 50–80% VO_2peak, performed in the same 60 min session, 3 days/weeks, for 12 weeks. Body composition, dietary intake, aerobic fitness (VO_2peak), muscular strength (1 RM), glycaemia, insulinemia, lipid profile and inflammatory markers (C-reactive protein, interleukin-6, tumour necrosis factor-alpha, interleukin-10, leptin, resistin and adiponectin) were measured before and after intervention. There was a significant decrease in body fat (P < 0.01) and increase in fat-free mass (P < 0.01), VO_2peak (P < 0.01), 1 RM for leg press (P < 0.01) and bench press (P < 0.01) in the overweight training group. Concomitantly, this group presented significant decreases in serum concentrations of C-reactive protein (P < 0.05) and leptin (P < 0.05), as well as in insulin resistance (P < 0.05) after the experimental period. In conclusion, 12 weeks of combined training without caloric restriction reduced inflammatory markers associated with obesity in overweight girls.  相似文献   

History of Science in Science Education: Development and Validation of a Checklist for Analysing the Historical Content of Science Textbooks     

Laurinda Leite 《Science & Education》2002,11(4):333-359

One of the aspects science education should focus on is learning about science.Achieving a good understanding of this aspect requires, among others, the useof the history of science. There is some evidence that teachers rely heavily ontextbooks to select the historical content they include in their physical sciencelessons. On the other hand, Portuguese physical science syllabuses are not veryexplicit about the teaching of the science. Therefore, textbook writers may notfeel compelled to give enough importance to the history of science in their textbooksand consequently little history of science will pervade the science lessons. This paperaims to present a theoretically grounded checklist developed for analysing the historical content of science textbooks. Five physics textbooks that are different with regard to historical content were analysed. Inter-ratter agreement was used in order to validate the checklist. The results of the analysis show that the checklist is able to reveal differences among textbooks and that the historical content included in the textbooks is hardly able to give students an adequate image of science and scientists' work.  相似文献   

Increasing the impact of a Master’s programme on teacher leadership and school development by means of boundary crossing     

Marco Snoek  Mascha Enthoven  Joseph Kessels  Monique Volman 《International Journal of Leadership in Education》2017,20(1):26-56

In this case study, we investigate how the development and impact of teacher leadership through a Master’s programme can be supported by a design that encourages boundary crossing activities between schools and universities. The case study focuses on 42 experienced teachers from three vocational colleges who were promoted to senior teacher positions and participated in a Master’s programme. Through individual and focus group interviews, data were collected on how boundary crossing activities can connect professional development and school development, and on favourable conditions for effective boundary crossing. The study shows that strategic alignment and shared ownership between university and school, a collective approach with multiple participants from one school, and the use of boundary objects, created the conditions through which the Master’s programme could serve as a catalyst, stimulating innovation of work practices and development of new leadership practices. The leadership of the senior teachers initiated a development process that shifted from formally mandated forms of leadership to more culturally embedded forms of leadership. This case study leads to a new understanding of design criteria for Master’s programmes and boundary objects that can support the process of developing teacher leadership within schools by facilitating boundary crossing between university and school.  相似文献

Principal Recruitment: An Empirical Evaluation of a School District’s Internal Pool of Principal Certified Personnel   总被引：1，自引：0，他引：1  

Paul A. Winter  James S. Rinehart  Marco A. Muñoz 《Journal of Personnel Evaluation in Education》2002,16(2):129-141

Applicant pools for principal vacancies are shrinking nationwide. This shortage of job applicants requires school districts to evaluate their internal pools of principal certified personnel. In this study, 194 certified individuals from a large school district responded to a survey measuring attraction to the job of principal, current job satisfaction versus expected satisfaction in the job of principal, barriers to pursuing the job, and recommended changes in the job. Few participants intended to apply for principal vacancies due to age (median=51), lack of self-reported capability to do the job, and satisfaction with the current job. Participants perceived their job satisfaction would decrease on assuming the job of principal relative to factors such as time with family and job security, and increase relative to factors such as salary and opportunity to experience varied activities. Implications for principal recruitment and recommendations for restructuring the job are discussed.  相似文献   

Concurrent and longitudinal predictors of calculation skills in preschoolers     

Valentina Tobia  Paola Bonifacci  Gian Marco Marzocchi 《European Journal of Psychology of Education - EJPE》2016,31(2):155-174

Early calculation abilities in preschoolers are predictive of mathematics achievement in subsequent grades (e.g., Jordan et al. 2009). Two studies were conducted to evaluate concurrent and longitudinal predictors of early calculation skills. In the first study, 102 preschoolers (57.8 % female; mean age?=?60.57?±?8.66 months) were given vocabulary, language comprehension, and verbal working memory tasks and a test battery that evaluated components of early number competence (quantity comparison, counting, number line, size seriation, semantic knowledge of digits, visual-spatial memory). The children were also asked to complete early calculation tasks, including addition and subtraction calculations. The results of this task constituted the dependent variable. The results showed that vocabulary, size seriation, and visual-spatial memory were significant concurrent predictors of early calculation competence. In the second study, 43 children completed the early number competence battery at time 1 (53.5 % female; mean age?=?59.30?±?3.46 months) and the linguistic and early calculation tasks at time 2, about 10 months later (mean age?=?69.43?±?3.31 months). The analysis of the longitudinal predictors of early calculation showed significant effects for counting and size seriation. The implications for preschool assessment and intervention are discussed.  相似文献
