The results of an extensive survey of the senior academic staff of the Israeli universities on their use of electronic journals and databases are presented. The major findings are that the use of electronic sources is already widespread among the respondents and more than 50% found the electronic services indispensable. Disparities were found between the usage patterns in the different disciplines.  相似文献   

Effects of experimenting with physical and virtual manipulatives on students' conceptual understanding in heat and temperature     

Zacharias C. Zacharia  Georgios Olympiou  Marios Papaevripidou 《科学教学研究杂志》2008,45(9):1021-1035

This study aimed to investigate the comparative value of experimenting with physical manipulatives (PM) in a sequential combination with virtual manipulatives (VM), with the use of PM preceding the use of VM, and of experimenting with PM alone, with respect to changes in students' conceptual understanding in the domain of heat and temperature. A pre–post‐comparison study design was used which involved 62 undergraduate students that attended an introductory course in physics. The participants were randomly assigned to one experimental and one control group. Both groups used the same inquiry‐oriented curriculum materials. Participants in the control group used PM to conduct the experiments, whereas, participants in the experimental group used first PM and then VM. VM differed from PM in that it could provide the possibility of faster manipulation, whereas, it retained any other features and interactions of the study's subject domain identical to the PM condition. Conceptual tests were administered to assess students' understanding before, during, and after the study's treatments. Results indicated that experimenting with the combination of PM and VM enhanced students' conceptual understanding more than experimenting with PM alone. The use of VM was identified as the cause of this differentiation. © 2008 Wiley Periodicals, Inc. J Res Sci Teach 45: 1021–1035, 2008  相似文献   

“I May Be Crackin’, But Um Fackin’”: Racial Humor in The Watsons Go To Birmingham—1963     

Jonda C. McNair 《Children‘s Literature in Education》2008,39(3):201-212

This article examines the utilization of racial humor in Christopher Paul Curtis’ novel, The Watsons Go To Birmingham—1963. The theoretical perspectives that inform the analysis include critical race theory and humor theory. The results of the analysis reveal that the use of humor in this book is influenced to a significant degree by race and racism.  相似文献   

The effect of illustrations in arithmetic problem-solving: Effects of increased cognitive load     

Inez E. Berends  Ernest C.D.M. van Lieshout 《Learning and Instruction》2009,19(4):345-353

Arithmetic word problems are often presented accompanied by illustrations. The present study examined how different types of illustrations influence the speed and accuracy of performance of both good (n = 67) and poor arithmeticians (n = 63). Twenty-four arithmetic word problems were presented with four types of illustrations with increasing information value. The results show that illustrations can have a detrimental effect on performance on arithmetic word problems, produced by irrelevant, redundant or interacting sources of information. Principles from cognitive load theory are used to explain the results, in particular in relation to (poor) working memory ability.  相似文献

Evaluation in primary prevention: a must, II, The child psychiatry point of view     

C Marneffe  G Soumenkoff 《Child abuse & neglect》1986,10(1):53-61

The evaluation of any antenatal prevention program of child abuse and neglect is limited for statistical and ethical reasons, as shown in the first part of the present study (cf., The obstetrical viewpoint by G. Soumenkoff). The authors propose a child psychiatry model of evaluation. Use of the model is illustrated by a 4-year survey of 374 selected high-risk pregnant women followed in the antenatal out-patient department of St. Pieters Hospital in Brussels. A child psychiatrist worked together with several gynecologists, supporting the high-risk couples as well as their children. Several indirect evaluation methods of the quality of screening and the efficiency of the work are analyzed. Long-term evaluation of the children is an absolute necessity. In order to evaluate this type of approach, a simple questionnaire concerning the quality of life of the children under study was derived from a model used in pediatric oncology by the EORTC and adapted to the problems of abused children. One part was answered by the parents which allowed the researchers to evaluate their perception of the child. The second part was filled out by the sociomedical professionals who followed the child. The combination of these two views is rich in information concerning the patient as well as the parents' attitude toward their child.  相似文献
