Ultrasonography is increasingly used in medical education, but its impact on learning outcomes is unclear. Adding ultrasound may facilitate learning, but may also potentially overwhelm novice learners. Based upon the framework of cognitive load theory, this study seeks to evaluate the relationship between cognitive load associated with using ultrasound and learning outcomes. The use of ultrasound was hypothesized to facilitate learning in anatomy for 161 novice first‐year medical students. Using linear regression analyses, the relationship between reported cognitive load on using ultrasound and learning outcomes as measured by anatomy laboratory examination scores four weeks after ultrasound‐guided anatomy training was evaluated in consenting students. Second anatomy examination scores of students who were taught anatomy with ultrasound were compared with historical controls (those not taught with ultrasound). Ultrasound's perceived utility for learning was measured on a five‐point scale. Cognitive load on using ultrasound was measured on a nine‐point scale. Primary outcome was the laboratory examination score (60 questions). Learners found ultrasound useful for learning. Weighted factor score on “image interpretation” was negatively, but insignificantly, associated with examination scores [F (1,135) = 0.28, beta = ?0.22; P = 0.61]. Weighted factor score on “basic knobology” was positively and insignificantly associated with scores; [F (1,138) = 0.27, beta = 0.42; P = 0.60]. Cohorts exposed to ultrasound had significantly higher scores than historical controls (82.4% ± SD 8.6% vs. 78.8% ± 8.5%, Cohen's d = 0.41, P < 0.001). Using ultrasound to teach anatomy does not negatively impact learning and may improve learning outcomes. Anat Sci Educ 10: 144–151. © 2016 American Association of Anatomists.  相似文献   

The Financing of Extension Services: A Survey Among Rural Youth in Greece     

George Alexopoulos  Alex Koutsouris  Irene Tzouramani 《The Journal of Agricultural Education and Extension》2013,19(2):177-190

Abstract

Since its establishment in the early 1950s, the Greek Extension Service has undergone considerable changes. Especially after 1981, a bureaucratic–administrative role related to the implementation of the CAP has been undertaken. In parallel, in the international scene, governments have started experimenting with various cost-recovery mechanisms for extension. In front of such challenges, at both national and international levels, the current work intends to explore the willingness of young rural inhabitants to pay for advisory services. Drawing data from a large-scale survey and utilising probit analysis, the decomposition of the marginal effects of a series demographic, socioeconomic and spatial characteristics and information needs upon willingness to pay for extension is presented. The results show that under preconditions cost-recovery mechanisms may be employed in Greece; furthermore, it is argued that the Extension Service has to be restructured–reoriented.  相似文献

Characteristics of extracurricular physical activity and cognitive performance in adolescents. The AVENA study

Abstract

The aim of this report was to examine the associations between some characteristics (i.e., structure and number) of extracurricular physical activity (EPA) and cognitive performance in adolescents. A total of 1662 adolescents (880 girls; 13.0–18.5 years) from 5 Spanish cities (Granada, Madrid, Murcia, Santander and Zaragoza) were included in this study. Structure (organised and non-organised) and number of EPAs, and participation at vigorous intensity during EPA were self-reported. Cognitive performance (verbal, numeric and reasoning abilities, and an overall score) was measured with the “SRA-Test of Educational Ability”. Results showed that vigorous EPA was positively associated with all cognitive variables. Adolescents who practiced an organised EPA had higher scores in 3 of the 4 cognitive variables than those who practiced a non-organised EPA (all P < 0.05). Likewise, the group who participated in more than one EPA had higher cognitive performance in all variables than the group who participated in only one EPA (all P < 0.05). Regardless of potential confounder variables, including vigorous EPA, both structure and number of EPAs were each other independently associated with cognitive performance. Therefore, structure and number of EPAs may positively influence cognitive performance in adolescents. Participating in multiple, organised EPA may have benefits for cognitive performance.  相似文献   

‘Warrant’ revisited: Integrating mathematics teachers’ pedagogical and epistemological considerations into Toulmin’s model for argumentation     

Elena Nardi  Irene Biza  Theodossios Zachariades 《Educational Studies in Mathematics》2012,79(2):157-173

In this paper, we propose an approach to analysing teacher arguments that takes into account field dependence—namely, in Toulmin’s sense, the dependence of warrants deployed in an argument on the field of activity to which the argument relates. Freeman, to circumvent issues that emerge when we attempt to determine the field(s) that an argument relates to, proposed a classification of warrants (a priori, empirical, institutional and evaluative). Our approach to analysing teacher arguments proposes an adaptation of Freeman’s classification that distinguishes between: epistemological and pedagogical a priori warrants, professional and personal empirical warrants, epistemological and curricular institutional warrants, and evaluative warrants. Our proposition emerged from analyses conducted in the course of a written response and interview study that engages secondary mathematics teachers with classroom scenarios from the mathematical areas of analysis and algebra. The scenarios are hypothetical, grounded on seminal learning and teaching issues, and likely to occur in actual practice. To illustrate our proposed approach to analysing teacher arguments here, we draw on the data we collected through the use of one such scenario, the Tangent Task. We demonstrate how teacher arguments, not analysed for their mathematical accuracy only, can be reconsidered, arguably more productively, in the light of other teacher considerations and priorities: pedagogical, curricular, professional and personal.  相似文献   

The Teacher's Voice: Vocal training in teacher education     

Irene Velsvik Bele 《Scandinavian Journal of Educational Research》2013,57(1):41-57

The voice is a basic tool in human communication and an important factor in a positive self‐understanding and identity, both for the teacher's sense of profession and for the pupils' ability to express themselves orally; two perspectives of great importance in the Norwegian National Curriculum. Voice disorders are common among teachers world‐wide and seem to be increasing. Voice problems influence the teachers' ability to teach effectively. An historical review illustrates the significance of the oral tradition in Norwegian teacher education. Against the background of recent studies that show that voice training courses given to different professional groups prevent voice disorders, a proposal is presented for the organisation of vocal training in Norwegian teacher education. The purpose is to emphasise the clear link between teaching and voice disorders and to focus on the prevention of voice problems among teachers by reintroducing voice training in teacher training.  相似文献

RECALL SCORES OF OLD AND YOUNG PEOPLE AS A FUNCTION OF REGISTRATION INTERVALS     

Irene M. Hulicka  Douglas Wheeler 《Educational gerontology》2013,39(4):361-372

The subjects, 24 old (mean age, 69 yr) and 24 young (mean age, 19 yr) people, were given one learning trial on paired associate lists under each of four temporal conditions: (1) 3 sec study (association) interval; (2) self‐paced study interval; (3) self‐paced study interval and 4 sec registration interval; (4) self‐paced study and registration intervals. The response interval for the single recall trial was self‐paced for all conditions. The subject was instructed to use the registration interval to ensure that the association between the paired items was “fixed” in his or her mind. The recall scores of the elderly subjects but not the young subjects improved significantly as a function of the registration interval. The results suggest that with advanced age more time is required for information processing, and specifically for the registration of an association and/or its transfer from primary to secondary memory. The significant improvement of the older subjects from the paced‐study‐interval condition to the self‐paced‐study‐and‐registration‐intervals condition supports the contention that modification of conditions under which the older person is expected to perform can result in substantial performance increments.  相似文献
