This study explores elementary teacher perceptions related to the implementation of an online tutoring program. Teachers were surveyed regarding factors that affected use of the online tutoring program as a supplement to mathematics instruction. Results indicated that teachers overwhelmingly reported positive views of the training and support opportunities provided, as well as confidence in their level of knowledge and the ease of use of the program. Teachers also indicated strong support of the mathematical content and instructional value of the program. Each of these factors increases the likelihood that online tutoring programs such as the one implemented in this study will continue to be used among teachers as a supplement to mathematics instruction. 相似文献

In 15–16 year olds from Oslo, Norway, we investigated the occurrence of self‐reported dyslexia and reading/writing difficulties (RWD), and we measured dyslexic symptoms using the Duvan dyslexia screening test. The prevalence of self‐reported dyslexia was 8.2%, while 10.4% reported severe or moderate RWD. The group of self‐reported dyslexics obtained lower mean‐values on Duvan than the non‐dyslexic group (125.7 [SD = 20.2] versus 153.2 [SD = 23.4]), but not on the test of general ability. The questionnaire items on dyslexia and RWD, as well as gender, ethnicity and general ability, significantly predicted Duvan scores (explained variance, R 2 = 0.25). More research is needed to explore the precision of Duvan as a screening tool for dyslexic symptoms among Norwegian adolescents. 相似文献

This paper examines university social science and education students' views of research methodology, especially asking whether a negative research orientation towards quantitative methods exists. Finnish (n?=?196) and US (n?=?122) students answered a questionnaire concerning their views on quantitative, qualitative, empirical, and theoretical methods, their readiness to use quantitative and qualitative methods in their own research, and the difficulties they experienced in quantitative methods' learning. Students were clustered in groups according to their views. Students had varying combinations of views on the methods, that is different research orientations towards methods were found in both countries. Some of the students had a dichotic attitude towards quantitative and qualitative methods; they seemed to “choose their side” between these methods. In both countries a negative research orientation towards quantitative methods was found. It was connected with either difficulties in quantitative methods' learning or with a lower appreciation of empirical methods than that of other students. Major subject and study year had no effect, so the views were not discipline‐specific and students seemed to already have them on entering university. Views were quite stable during the course. A reduction in difficulties experienced with quantitative methods' learning was connected with a lowered over‐appreciation of qualitative methods at the end of the course. 相似文献

It is, in part [the] nineteenth century war between the advocates of the humanities and of the sciences, in which intransigent positions were taken, that led finally to a situation which can only be called neither peace nor war‐‐ something like a condition of armed neutrality between scientific and humane studies, with an ever widening gulf between them, which it is the business of modern education, if not to abolish, at least to narrow [I].

The continually rising percentage of the elderly population and the demand for geriatric nursing care are dramatically related. While it is true that most undergraduate programs prepare nurses for the care of geriatric patients, most receive limited academic preparation in the nursing curriculum (Williams & Mezey, 2000). This is particularly true in the Philippines where there is no stand-alone geriatric nursing course. This phenomenological study purports to capture the lived experiences of Filipino nursing students' dilemmas in geriatric care. Five Filipino senior nursing students and three clinical faculty from a comprehensive university in the Philippines were purposely chosen for the study. A two-part instrumentation was used. The first is the robotfoto, a Dutch term which means a cartographic sketch of the subject (Kelchtermans & Ballet, 2002). The second was a semi-structured face-to-face interview that was recorded with the consent of the participants. The full texts were phenomenologically reduced using a repertory grid to observe both cool and warm analyses, which facilitates the identification of unique conceptual clusters. Findings of this study have described the elements that define student dilemmas in geriatric care. The emerged Students' Dilemmas in Geriatrics Causality Quadrant (SDGCQ), which consists of (a) Foundational Deficit, (b) Psychological Deficit, (c) Relational-Attitudinal Deficit, and (d) Occupational Deficit, are valuable discussion points for needed reforms in the present-day nursing curriculum. 相似文献

During the past decade, the benefits of HPT approaches used in the commercial sphere are being adopted in the much different world of donor‐funded development. The challenges of applying these strategies and methodologies to this complex and foreign arena require special consideration of application for real‐world results. The authors provide some insight from their combined 50+ years of work in this environment for prospective HPT professionals thinking to enter this critical and growing sector. 相似文献

Informetric researchers have long chafed at the limitations of bibliographic databases for their analyses, without being able to visualize or develop real solutions to the problem. This paper describes a solution developed to provide for the specialist needs of informetric researchers. In a collaborative exercise between the fields of computer science and informetrics, data modelling was used in order to address the requirements of complex and dynamic informetric data. This paper reports on this modelling experience with its aim of building an object-relational database (ORDB) for informetric research purposes. The paper argues that ORM (object-relational model) is particularly suitable because it allows for the modelling of complex data and accommodates the various data source formats and standards used by a variety of bibliographic databases. Further, ORM captures the dynamic nature of informetric data by allowing user-defined data types and by embedding basic statistical calculating tools as object functions in these user-defined data types. The main ideas of the paper are implemented in an Oracle database management system. 相似文献

Background/aim: Currently, the liver is cold-preserved at 0-4 ℃ for experimental and clinical purposes. Here, we investigated whether milder hypothermia during the initial phase of the preservation period was beneficial for liver viability upon reperfusion. Methods: In the first set of experiments, rat livers were preserved either conventionally in clinically used histidine-trypthopan-ketoglutarate (HTK) solution (Group A: 45 min and Group B: 24 h) or by slow cooling HTK solution (from 13 ℃ to 3 ℃) during the initial 45 min of preservation (Group C: 24 h). In the second set of experiments, additional groups of livers were evaluated: Group BB-preservation according to Group B and Group CC-preservation according to Group C. Further, some livers were preserved at 13 ℃ for 24 h. Livers were then reperfused using a blood-free perfusion model. Results: Bile production was approximately 2-fold greater in Group C compared to Group B. Alanine transaminase (ALT) and aspartate transaminase (AST) release into perfusate were 2-3-fold higher in Group B compared to Group C. No significant differences were found in ALT and AST release between Group C and Group A. Livers in Group CC compared to Group BB exhibited significantly lower portal resistance, greater oxygen consumption and bromosulfophthalein excretion into bile and lower lactate dehydrogenase (LDH) release into perfusate. Histological evaluation of tissue sections in Group BB showed parenchymal dystrophy of hepatocytes, while dystrophy ofhepatocytes was absent in Group CC. Livers preserved at 13 ℃ for 24 h exhibited severe ischemic injury Conclusion: These results suggest that the conventional way of liver preservation is not suitable at least for rat livers and that slow cooling of HTK solution during the initial phase of cold storage can improve liver viability during reperfusion. 相似文献
