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

PISA presents a new image for academic achievement, which has prompted Japanese education reforms over the past decade to innovate teaching and learning for ‘PISA-style literacy’. Supported by theoretical foundations, particularly with regard to the concept of ‘PISA literacy’ and ‘authentic assessment’, these reforms have accomplished progress in the focus on higher order competencies, such as application and the development of new assessment strategies. However, more recently, various critical discussions of ‘PISA literacy’ are underway in the Japanese academy. They interrogate it more critically and reveal the narrow emphasis on functional application and technical operation. Current assessment practices, which tend to fall into ‘criteria compliance’, are in urgent need of review. There is a need to extend the critical discussions in progress to the new assessment strategies. This paper responds to this, by considering the Japanese acceptance of ‘PISA literacy’ and its assessment, discussing the features and limitations. 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

To investigate the effects of a single high-load (80% of one repetition maximum [1RM]) set with additional drop sets descending to a low-load (30% 1RM) without recovery intervals on muscle strength, endurance, and size in untrained young men. Nine untrained young men performed dumbbell curls to concentric failure 2–3 days per week for 8 weeks. Each arm was randomly assigned to one of the following three conditions: 3 sets of high-load (HL, 80% 1RM) resistance exercise, 3 sets of low-load [LL, 30% 1RM] resistance exercise, and a single high-load (SDS) set with additional drop sets descending to a low-load. The mean training time per session, including recovery intervals, was lowest in the SDS condition. Elbow flexor muscle cross-sectional area (CSA) increased similarly in all three conditions. Maximum isometric and 1RM strength of the elbow flexors increased from pre to post only in the HL and SDS conditions. Muscular endurance measured by maximum repetitions at 30% 1RM increased only in the LL and SDS conditions. A SDS resistance training program can simultaneously increase muscle CSA, strength, and endurance in untrained young men, even with lower training time compared to typical resistance exercise protocols using only high- or low-loads. 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

Comparisons over time of the inputs and outputs of polymer chemistry research in Japan show that the academic institutionalisation of this discipline took place after the most creative period in its research had been reached. Early interest in the development of the field had been stimulated by Japanese industry in response to major discoveries made in Western Europe and the USA. 相似文献

We present a microfluidic device designed for maintenance and culture of non-adherent mammalian cells, which enables both recirculation and refreshing of medium, as well as easy harvesting of cells from the device. We demonstrate fabrication of a novel microfluidic device utilizing Braille perfusion for peristaltic fluid flow to enable switching between recirculation and refresh flow modes. Utilizing fluid flow simulations and the human promyelocytic leukemia cell line, HL-60, non-adherent cells, we demonstrate the utility of this RECIR-REFRESH device. With computer simulations, we profiled fluid flow and concentration gradients of autocrine factors and found that the geometry of the cell culture well plays a key role in cell entrapping and retaining autocrine and soluble factors. We subjected HL-60 cells, in the device, to a treatment regimen of 1.25% dimethylsulfoxide, every other day, to provoke differentiation and measured subsequent expression of CD11b on day 2 and day 4 and tumor necrosis factor-alpha (TNF-α) on day 4. Our findings display perfusion sensitive CD11b expression, but not TNF-α build-up, by day 4 of culture, with a 1:1 ratio of recirculation to refresh flow yielding the greatest increase in CD11b levels. RECIR-REFRESH facilitates programmable levels of cell differentiation in a HL-60 non-adherent cell population and can be expanded to other types of non-adherent cells such as hematopoietic stem cells. 相似文献

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
