The time, material, and staff‐consuming nature of anatomy's traditional pen‐and‐paper assessment system, the increase in the number of students enrolling in medical schools and the ever‐escalating workload of academic staff have made the use of computer‐based assessment (CBA) an attractive proposition. To understand the impact of such shift in the assessment method, an experimental study evaluating its effect on students’ performance was designed. Additionally, students’ opinions toward CBA were gathered. Second‐year medical students attending a Clinical Anatomy course were randomized by clusters in two groups. The pen‐and‐paper group attended two sessions, each consisting of a traditional sectional anatomy steeplechase followed by a theoretical examination, while the computer group was involved in two similar sessions conducted in a computerized environment. At the end of each of the computer sessions, students in this group filled an anonymous questionnaire. In the first session, pen‐and‐paper group students scored significantly better than computer‐group students in both the steeplechase (mean ± standard deviation: 66.00 ± 14.15% vs. 43.50 ± 19.10%; P < 0.001) and the theoretical examination (52.50 ± 12.70% vs. 39.00 ± 21.10%; P < 0.001). In the second session, no statistically significant differences were found for both the steeplechase (59.50 ± 17.30% vs. 54.50 ± 17.00%; P = 0.085) and the theoretical examination (57.50 ± 13.70% vs. 54.00 ± 14.30%; P = 0.161). Besides, an intersession improvement in students’ perceptions toward CBA was registered. These results suggest that, after a familiarization period, CBA might be a performance equivalent and student accepted alternative to clinical anatomy pen‐and‐paper theoretical and practical examinations.

INTRODUCTION Sustainable development is commonly definedas meeting the needs of the present without compro-mising the ability of future generations to meet theirown needs (WCED, 1987). All industries, includingthe construction industry should contribute to themission. Compared to other industries, constructionactivities are generally considered to have more im-pact on the environment, which provides the basicconditions for the sustainability and development oflife on the Earth.

Comparison of Students’ Performance on Algorithmic, Conceptual and Graphical Chemistry Gas Problems     

Bayram Co&#;tu 《Journal of Science Education and Technology》2007,16(5):379-386

The purpose of this study was to determine whether there were significant differences in students’ performances amongst conceptual, algorithmic and graphical questions tests. Seventy-one eleventh-grade students were involved in this study. In order to assess students’ performance, conceptual, graphical and algorithmic questions tests were utilized. Students’ performances in each test were analyzed statistically. Statistical analysis using one-way ANOVA of student tests scores pointed to statistically significant differences amongst each of three test scores (P < 0.05) in favor of the conceptual test. Further analyses were conducted to compare one type of questions with others. From these comparisons, positive relationships were found between conceptual understanding and algorithmic understanding and between conceptual understanding and graphical understanding. Also, results obtained indicated that most of the students lack of graphical understanding. The results suggest that students need more training about graphical understanding.  相似文献   

工作满意度、组织承诺与关系绩效的关系实证研究     

向倩雯 《四川教育学院学报》2007,23(1):101-103

通过在成都、广州、深圳一些企业的实证研究,探讨组织承诺、工作满意度与关系绩效之间的关系,发现组织承诺三维度、工作满意度五维度与关系绩效两维度之间几乎都具有非常显著的相关关系;但是将工作满意度和组织承诺作为关系绩效的预测变量时,发现二者的因果关系非常不显著,因此推测工作满意度、组织承诺可能是关系绩效的前因中介变量或者调节变量。  相似文献

The role of personal best (PB) and dichotomous achievement goals in students’ academic motivation and engagement: a longitudinal investigation     

Andrew J. Martin  Andrew J. Elliot 《教育心理学》2016,36(7):1285-1302

This study assessed the role of prior personal best goals in predicting subsequent academic motivation and engagement. A total of 1160 high school students participated in a longitudinal survey study exploring the extent to which personal best and mastery and performance (dichotomous) achievement goals predict students’ academic motivation and engagement across the course of a full academic year. Findings showed that personal best goals predicted higher motivation and engagement a year later. Along with personal best goals, mastery goals also predicted higher motivation and engagement, while the role of performance goals was either neutral or negative. These findings provide support for the contention that personal best goals are associated with higher motivation and engagement across time.  相似文献   

Preparation and Tribological Performance of Novel Organotin Compound as Lubricant Additive     

刘仁德陶德华  赵源曹卫国  张建华付尚发 《上海大学学报(英文版)》2004,8(1):96-100

Oil-soluble stannous naphthenate (SN) is synthesized by using naphthenatic acid and SnO. And its molecular structure is confirmed by IR and multielement oil analyzer (MOA). The tribological performances of the organotin as lubricant additive are evaluated with a four-ball friction and wear tester. These experiments indicate that the wear scar diameter (WSD) and friction coefficient are diminished while the load-carrying capability increased by comparison with that of base oil. The elemental composition of the boundary lubricating film is examined by means of Auger electron spectroscopy (AES). Synergistic effect is found in the load-carrying capability of the complex of SN and sulfured olefin. The analytical results of AES indicate that the good performance of stannous naphthenate is attributed to the formation of a boundary lubricating film containing Sn on the rubbed surface.  相似文献   

The Design of Competency-Based Performance Assessment in E-Learning     

Dominique M. A. Sluijsmans  Frans J. Prins  Rob L. Martens 《Learning Environments Research》2006,9(1):45-66

This article focuses on the design of competency-based performance assessment in e-learning. Though effort has been invested in designing powerful e-learning environments, relatively little attention has been paid to the design of valid and reliable assessments in such environments, leaving many questions to educational developers and teachers. As a solution to this problem, a systematic approach to designing performance assessments in e-learning contexts is presented, partly based on the 4C/ID model. This model enables the construction of realistic whole tasks instead of advocating education that is restricted to more isolated skills. A new assessment procedure also implies an alternative view of instructional design, learning and assessment. The requirements for the learning environment are addressed. Examples from a virtual seminar are presented to illustrate the design approach. The article concludes with the identification of possible pitfalls related to the approach and gives directions for future research.  相似文献   

Testing results analysis of contact materials＇ electrical contact performance     

WANG Jing-qin WANG Hai-tao WEN Ming ZHU Yan-cai 《浙江大学学报(A卷英文版)》2007,8(3):459-463

Because of the different ways in which contact materials work, the basic requirements for silver metal oxide contact materials are different. They are anti-welded and anti-erosion when closed, anti-erosion when broken, and arc easily moved and have smaller contact resistance. In this paper, La2O3 is used as a stable oxide in contact material to replace CdO. A new type of Ag/SnO2-La2O3-Bi2O3 contact material is first obtained through using powder metallurgical method. Then electrical contact material parameter tester is used to test the electrical contact performance of the contact material. Through experiments, the arcing voltage and current curves, arcing energy curves, fusion power curves while broken and contact resistance while closed were obtained. Analysis of the results showed that the addition of La2O3 makes the contact material have the following advantages： smaller electrical wear, smaller arc energy, smaller contact resistance and arc is more easily extinguished.  相似文献
