Understanding teachers as change agents: An investigation of primary school teachers’ self-perception     

H. R. M. A. van der Heijden  D. Beijaard  J. J. M. Geldens  H. L. Popeijus 《Journal of Educational Change》2018,19(3):347-373

This study reports on a large-scale survey on primary school teachers’ perceptions of being change agents and the extent to which these perceptions are related to personality and contextual factors. A principal component analysis and confirmatory factor analysis revealed nine characteristics of teachers as change agents. Personality and contextual factors are related to teachers’ perceptions of being a change agent. Four teacher profiles were distinguished according to the varying degrees of teachers’ perceptions of themselves as change agents. This study adds to the further understanding of teachers as change agents, their characteristics and how these characteristics are related to personality and contextual factors.  相似文献   

A response to David Kirk: personal/professional views from US authors     

Peter Hastie  Hans van der Mars 《Sport, Education and Society》2013,18(3):333-342

This paper represents the views of two scholars in the USA with respect to the scholar lecture presented by David Kirk at the 2012 BERA – Physical Education and Sport Pedagogy (PESP) Special Interest Group meeting. We discuss how two unique features of the American universities have an impact on both the corporate nature of our work and our scholarship. These features are described as ‘the notion of outreach scholarship’ and the ‘nature of giving.’ In addition, we discuss our different situations and how they affect our ability to do the best academic work. We can, and by consequence, give our best efforts to resist the hegemony of corporatization.  相似文献   

Alterations in kinematics and muscle activation patterns with the addition of a kipping action during a pull-up activity     

Christopher Dinunzio  Nathaniel Porter  John Van Scoy  Derrick Cordice 《Sports biomechanics / International Society of Biomechanics in Sports》2013,12(6):622-635

Recently, addition of a gymnastics glide kip to a standard pull-up (SPU) has resulted in the kipping pull-up (KPU). Changes in muscle activation and kinematics were evaluated with eleven athletes performing sets of 5 SPU and 5 KPU. Surface electromyography of upper body and lower body muscles was recorded along with movement kinematics obtained via markers and motion tracking software. Most kinematic variables were significantly higher in the KPU including (KPU minus SPU deg): Max hip angle (48.8° ± 6.8°, p < 0.001) and max knee angle (56.5° ± 11.3°, p < 0.001). The recruitment of core and lower body muscles was significantly higher in the KPU (% MVIC increase): rectus abdominis (28.7 ± 4.7%, p < 0.001), external oblique (21.8 ± 4.1%, p < 0.001), iliopsoas (26.1 ± 5.5%, p = 0.001) and tensor fasciae latae (13.5 ± 2.3%, p < 0.001). Correspondingly, the biceps brachii had lower activation in the KPU (% MVIC decrease): (26.7 ± 0.6%, p = 0.006). Depending on the athlete’s goal, they may elect to perform an SPU for higher upper body muscle activation; or the KPU for more full-body activation with the potential to perform more repetitions through reduced upper body fatigue.  相似文献   

The influence of test-based accountability policies on teacher stress and instructional practices: a moderated mediation model     

Nathaniel P. von der Embse  Alexander M. Schoemann  Stephen P. Kilgus  Maribeth Wicoff  Mark Bowler 《教育心理学》2017,37(3):312-331

The present study examined the use of student test performance for merit pay and teacher evaluation as predictive of both educator stress and counterproductive teaching practices, and the moderating role of perceived test value. Structural equation modelling of data from a sample of 7281 educators in a South-eastern state in the United States supported the hypothesis that educators who perceived the test as an invalid measure of teaching effectiveness were more likely to report high levels of test stress and to use counterproductive teaching practices, including fear appeals, in an attempt to motivate students for test-taking. This study provides initial evidence for the hypothesised relationships of test-based accountability policy with teacher mental health and instructional practices. Implications for research and practice are discussed.  相似文献   

The effects of teacher expectation interventions on teachers’ expectations and student achievement: narrative review and meta-analysis     

Hester de Boer  Anneke C. Timmermans  Margaretha P. C. van der Werf 《Educational Research and Evaluation》2018,24(3-5):180-200

ABSTRACT

This study provides a systematic review of the effects of 19 teacher expectation interventions. Prior research on teacher expectations primarily focussed on correlational relationships with student and teacher characteristics, leaving open the questions of whether it is possible to raise teacher expectations and to prevent (too) low expectations from having detrimental effects on student achievement. These questions were the scope of the current review. We distinguished 3 types of interventions: changing teacher behaviour, creating awareness of expectancy effects, and addressing the beliefs underlying the expectations. The results indicated that it was possible to raise teacher expectations and subsequent student achievement. We found summary effects of Hedges’ g?=?0.38 and 0.30, respectively. The narrative review suggested that the intervention type did not affect the effectiveness, but teacher support for the intervention did. However, verification of this suggestion with moderator analysis was not possible due to the limited number of interventions.  相似文献   

The concept of development and the development of concepts. Education and development in Vygotsky’s thinking     

René van der Veer 《European Journal of Psychology of Education - EJPE》1994,9(4):293-300

A major theme of Vygotsky’s research in the latter part of his life was the theme of concept formation or conceptual development in child development. He argued that the acquisition of mature scientific (academic) concepts forms the crowning achievement of adolescsence. Mature conceptual thinking positively influences the cognitive domain but also the aesthetic reactions and emotions. Conversely, the breakdown of conceptual thinking in pathology will lead to severe intellectual impairment but also to emotional dullness etc. In this paper it is claimed that this view is highly interesting but a number of criticisms are raised. Specifically, it is argued that (1) the resulting view is overly rationalistic; (2) the notion of scientific concepts seems to imply a somewhat static view of science; and (3) Vygotsky was perhaps too optimistic about the possibility of transfer of scientific (conceptual) thinking to other domains.  相似文献   

Gender Differences in Child Aggression: Relations With Gender‐Differentiated Parenting and Parents’ Gender‐Role Stereotypes          下载免费PDF全文

Joyce J. Endendijk  Marleen G. Groeneveld  Lotte D. van der Pol  Sheila R. van Berkel  Elizabeth T. Hallers‐Haalboom  Marian J. Bakermans‐Kranenburg  Judi Mesman 《Child development》2017,88(1):299-316

This longitudinal study examines the association between child gender and child aggression via parents’ physical control, moderated by parents’ gender‐role stereotypes in a sample of 299 two‐parent families with a 3‐year‐old child in the Netherlands. Fathers with strong stereotypical gender‐role attitudes and mothers were observed to use more physical control strategies with boys than with girls, whereas fathers with strong counterstereotypical attitudes toward gender roles used more physical control with girls than with boys. Moreover, when fathers had strong attitudes toward gender roles (stereotypical or counterstereotypical), their differential treatment of boys and girls completely accounted for the gender differences in children's aggressive behavior a year later. Mothers’ gender‐differentiated parenting practices were unrelated to gender differences in child aggression.  相似文献   

The Role of Students’ Personality Characteristics, Self-Perceived Competence and Learning Conceptions in the Acquisition and Development of Social Communicative Competence: A Longitudinal Study     

A. W. E. A. Bakx  J. M. M. Van der Sanden  K. Sijtsma  M. A. Croon  Y. J. M. Vermetten 《Higher Education》2006,51(1):71-104

An important purpose of higher social work education is to guide students to acquire and develop social-communicative competencies. The purpose of this study was to investigate the role students’ personality characteristics, self-perceived communicative competence and learning conceptions play in the acquisition and development of social-communicative competencies. We designed and tested a hypothetical model on the student-related variables – self-perceived communicative competence, learning conceptions and reported learning activities regarding communication – in relation to performance scores. We were interested in developmental trends in the above mentioned variables. We also wanted to gain insight into the relationships among the variables. The study was set up according to a longitudinal, within-subjects design in order to study intra-individual changes. One-hundred and twenty-three first-year social-work students participated in this study. Many changes were found in students characteristics, reported deployed learning activities and study results during their first academic year. Except for confidence in “showing sympathy”, which was already relatively high at the beginning of the study, all scores on aspects of students’ self-perceived social-communicative competence increased. Assessment scores on comparable communication tests also increased significantly. Extraversion and emotional stability were the only two personality characteristics, which seemed rather stable. Agreeableness decreased while autonomy increased continuously during the first academic year. It seemed to be possible to set up a model, which may serve as a starting point for further research into the development of social-communicative competence.  相似文献   

A Comparison of Item-Selection Methods for Adaptive Tests with Content Constraints     

Wim J. van der Linden 《Journal of Educational Measurement》2005,42(3):283-302

In test assembly, a fundamental difference exists between algorithms that select a test sequentially or simultaneously. Sequential assembly allows us to optimize an objective function at the examinee's ability estimate, such as the test information function in computerized adaptive testing. But it leads to the non-trivial problem of how to realize a set of content constraints on the test—a problem more naturally solved by a simultaneous item-selection method. Three main item-selection methods in adaptive testing offer solutions to this dilemma. The spiraling method moves item selection across categories of items in the pool proportionally to the numbers needed from them. Item selection by the weighted-deviations method (WDM) and the shadow test approach (STA) is based on projections of the future consequences of selecting an item. These two methods differ in that the former calculates a projection of a weighted sum of the attributes of the eventual test and the latter a projection of the test itself. The pros and cons of these methods are analyzed. An empirical comparison between the WDM and STA was conducted for an adaptive version of the Law School Admission Test (LSAT), which showed equally good item-exposure rates but violations of some of the constraints and larger bias and inaccuracy of the ability estimator for the WDM.  相似文献   

A Strategy for Optimizing Item-Pool Management     

Adelaide Ariel  Wim J. van der Linden  Bernard P. Veldkamp 《Journal of Educational Measurement》2006,43(2):85-96

Item-pool management requires a balancing act between the input of new items into the pool and the output of tests assembled from it. A strategy for optimizing item-pool management is presented that is based on the idea of a periodic update of an optimal blueprint for the item pool to tune item production to test assembly. A simulation study with scenarios involving different levels of quality of the initial item pool, item writing, and management for a previous item pool from the Law School Admission Test (LSAT) showed that good item-pool management had about the same main effects on the item-writing costs and the number of feasible tests as good item writing, but the two factors showed strong interaction effects.  相似文献
