This paper reports design experiments on two Japanese elementary science lesson units in a sixth‐grade classroom supported by computer support for collaborative learning (CSCL) technology as a collaborative reflection tool. We took different approaches in the experiments depending on their instructional goals. In the unit ‘air and how things burn’, we designed the unit where groups of students engaged in building theories on ‘how a candle stops burning in a closed jar’. In the unit ‘characteristics of various solutions’, groups of students collaboratively constructed a pH scale as knowledge artefact. In both studies, the CSCL technology was implemented mainly for facilitating collaboration between groups. Results showed that: (1) students were more likely to engage in symmetric communication (i.e. between groups as well as within groups) in the second unit, and (2) they were also more idea‐centred and more frequently shared their ideas in the second unit. The results were discussed from the perspectives of the scientific practices students engaged in and task structure. 相似文献

An experiment was conducted to evaluate constructive memory in fourth-grade low-SES black and middle-SES white children. The children were read nine short passages; each passage was composed of two premise statements and a filler sentence. The children were tested by a recognition procedure. Thirty-six test sentences were presented randomly. Four sentences were associated with each passage (true premise, false premise, true inference, and false inference). Subjects were asked to make yes/no recognition decisions based on whether the test sentence was identical to a sentence presented at study. Middle-SES white children made few errors, except to true inference test sentences. This pattern of performance is consistent with the constructive view of memory. Low-SES black children also had a high error rate to true inference items. However, this outcome may not reflect constructive memory because they also had a high error rate to some of the other types of test sentences. 相似文献

Japan's universities were established in order to import Western knowledge and ideas to assist in the development of the nation beginning in the mid-19th century. Because it was never colonized and because it has sucessfully developed not only its academic system but also its economy, Japan is a particularly significant case study. Japan's academic development can be seen in two phases. First there was a window shopping period in which many Western models were explored and some partially adopted. Second, there has been an involvement mode in which specific Western models are adopted. This essay follows the development of Japanese higher education through its various phases, including the post World War Two impact of the United States and the growth of a mass university system. The process of internationalization of various foreign influences is examined. 相似文献

In October 2003, Californians voted in the high-profile gubernatorial recall election and on what is referred to as the “Racial Privacy Initiative.” The Initiative sought to prohibit the gathering of racial data in education and state employment. Unlike recent such initiatives addressing California's racial laws, this one was unsuccessful: 62 percent of voters said no. This essay examines the discourse surrounding the initiative over its three-year history and traces the rhetorical dynamics that led to its defeat. The analysis details the implications of this moment for hegemonic processes in general and as they relate to the specifics of race. 相似文献

Aim: Recent meta-analyses of the literature confirmed the association between the RR+RX genotype of the ACTN3 R577X polymorphism and elite sprint/power athletic status in Europeans but not in Asians and Africans, while the association between the R577X genotype and elite endurance athlete status is less convincing. The aim of the present study was to investigate the association between the ACTN3 R577X genotype and elite athlete status in a large Asian (Japanese) cohort of track and field athletes. Methods: One-thousand fifty-seven Japanese track and field athletes (627 sprint/power athletes and 430 endurance athletes) and 810 Japanese controls were genotyped for the ACTN3 R577X polymorphism (rs1815739) by using the TaqMan® SNP Genotyping Assay. Results: Elite sprint/power athletes had a higher frequency of the RR+RX genotype than the controls (OR: 1.59, 95% CI: 1.16–2.18; P?=?.003). A significant linear correlation was found between the RR?+?RX genotype and athlete status (i.e. regional?P?=?.001 for trend) and long-distance runners (regional: 65%, national: 72%, international: 82%; P?=?.030 for trend). Conclusions: The data obtained for this large Asian (Japanese) cohort of track and field athletes served to confirm the association between the RR?+?RX genotype of the ACTN3 R577X polymorphism and elite sprint/power athlete status and also the association between the ACTN3 RR?+?RX genotype and long-distance running athletic status. 相似文献

The purpose of this study was to examine research and trends in knowledge management in education (KME) published in selected professional sources during the period 1990–2008. Citation analysis was used in this study to investigate documents related to KME, which were indexed in the Web of Science, Education Researches Information Center and ScienceDirect. Knowledge management‐ and educational technology‐related keywords were used jointly in the search for documents. There were a total of 125 documents judged to be relevant to the field of KME and were analysed. As a result of this study, it can be seen that the documents and the number of citations related to the KME field has been continuously increasing since 2005. It is recommended that a combination of citation analysis and other types of analyses should be used in future research studies. 相似文献

Introduction
Acute kidney injury (AKI) is common in neonatal intensive care units (NICU). In recent years, every effort is made for early detection of AKI. Our hypothesis was that serum neutrophil gelatinase-associated lipocalin (sNGAL) may be a reliable screening test for early diagnosis of AKI in premature neonates after perinatal asphyxia. Therefore, our aim was to assess the diagnostic accuracy of sNGAL for AKI in premature asphyxiated neonates.Materials and methods
AKI was defined in the third day of life (DOL 3) as a serum creatinine (sCr) increase ≥ 26.5 μmol/L from baseline (the lowest previous sCr). According to the increase of sCr, AKI patients were divided in AKIN1 (sCr increase up to 1.9 baseline) and AKIN2 (sCr increase from 2.0 to 2.9 baseline). sNGAL levels were measured on DOL 1, 3 and 7.Results
AKI was diagnosed in 73 (0.676) of 108 enrolled premature asphyxiated neonates. Sixty one patients (0.836) were classified in AKIN1 and 12 patients (0.164) in AKIN2. sNGAL reached the maximal concentrations on DOL 1 within 4 hours after admission to NICU, being higher in AKI compared with no-AKI group (160.8 ± 113.1 vs. 87.1 ± 81.6; P < 0.001) as well as in AKIN2 compared with AKIN1 group (222.8 ± 112.9 vs. 147.8 ± 109.9; P < 0.001). The best areas under the receiver operating characteristic curves (AUC) for prediction of AKI were 0.72 [95% (0.62-0.80) P < 0.001] on DOL1 at 2h and 0.72 [95% (0.63-0.80) P < 0.001] at 4th hour after admission respectively. The corresponding sNGAL cutoff concentrations were 84.87 ng/mL (sensitivity 69.0% and specificity 71.9%) and 89.43 ng/mL (sensitivity 65.7% and specificity 74.3%).Conclusions
In premature asphyxiated neonates sNGAL measured within the first 4 hours of DOL 1 is predictive of the occurrence and severity of AKI. Therefore, plasma levels of NGAL may be used for early diagnosis of AKI in these patients.Key words: serum neutrophil gelatinase-associated lipocalin, acute kidney injury, premature neonates, biomarker 相似文献9.
The research function of universities in Japan 总被引：1，自引：0，他引：1
Japan has long led the trend towards privatization of Research andDevelopment (R&D). With the recent establishment of corporate R&Dfacilities overseas, this has become more international in character. Therelative impoverishment of Japanese academic science has only recently begunto be addressed by the government. Despite the neglect, there appears to bea gradual increase in Japanese academic research, but international researchcollaborations are still quite limited in number. There are growing tieswith industry, but industry has been slow to recognize the value of graduateschool training. Stronger links may promote greater research activity, butwithout reforms to the structure of the education system and Ministry ofEducation policies, Japan will not be prepared to meet the challenge of the21st century, and the need for a highly-skilled, innovative workforce. 相似文献

The Department of Education in the Philippines has undertaken initiatives to restructure the curriculum for secondary schools as part of its ongoing effort to improve the quality of learning. After a decade of study, the Department produced a new basic education curriculum, as the 2002 Basic Education Curriculum. All public schools in the country were mandated to implement the curriculum at the start of 2002–2003 school year. Makabayan (nationalistic or patriotic) is one of the learning areas in the Basic Education Curriculum along with English, Filipino, Science and Mathematics. Makabayan from First to Fourth Year is designed to develop the personal, social and work special skills of learners especially their interpersonal skills, empathy with other cultures, vocational efficiency, problem-solving, and decision-making in daily life, that is, to develop socio-cultural and politico-economic literacy. This paper describes the context and content of the Makabayan curriculum and the extent to which it develops in learners a sense of citizenship, that is, a healthy personal and national self-concept. To delimit scope, this paper focuses on the study of geography only as one of the components of Araling Panlipunan (Social Studies) in the secondary school Makabayan Curriculum, using the results of a study of third year high school students' learning of geographic knowledge and skills as bases of empirical data. Key Words: citizenship, geographic literacy and competency, Makabayan curriculum, secondary education 相似文献
