博士生课程参与困境的诱因及其调适 ——基于“双一流”高校教育学博士生的个案研究

博士生群体构成的日益多样化呼唤博士生培养模式的变革。当前博士生课程存在学生参与度低等问题,其合理性正面临挑战。对我国三所“双一流”高校教育学专业博士生的深度访谈发现,课程制度设计的模糊性与有限性导致学生选课决策更多表现为既定约束下的次优博弈。此种选课机制与课程教学质量的不确定性相结合,最终引致学生课堂参与行为的分异。博士生通过旁听、权变等非制度化实践,一定程度上彰显了学习者在教育场域中的能动性。未来,有必要增加博士生课程制度的弹性,重申有效互动的价值。     

Tandem array of nanoelectronic readers embedded coplanar to a fluidic nanochannel for correlated single biopolymer analysis

We have developed a two-step electron-beam lithography process to fabricate a tandem array of three pairs of tip-like gold nanoelectronic detectors with electrode gap size as small as 9 nm, embedded in a coplanar fashion to 60 nm deep, 100 nm wide, and up to 150 μm long nanochannels coupled to a world-micro-nanofluidic interface for easy sample introduction. Experimental tests with a sealed device using DNA-protein complexes demonstrate the coplanarity of the nanoelectrodes to the nanochannel surface. Further, this device could improve transverse current detection by correlated time-of-flight measurements of translocating samples, and serve as an autocalibrated velocimeter and nanoscale tandem Coulter counters for single molecule analysis of heterogeneous samples.

全站式陀螺仪定向数据处理及系统开发

针对隧道施工中导线测量存在的方向误差累积问题,探讨全站式陀螺仪加测地下导线定向边及其数据处理方法,以提高定向边精度。由于全站式陀螺仪内置的数据处理软件只能计算出陀螺方位角,而实际应用中需要的定向边的坐标方位角仍然停留在笔算阶段,为此开发全站式陀螺仪定向测量数据处理系统,并结合西秦岭隧道陀螺定向测量数据对系统的正确性进行验证。     

Information Economy and Changing Occupational Structure in Singapore

Using population census data since 1921, this article traces changes in employment and occupational structure in Singapore in the past 80 years. This is a follow-up to an earlier paper by Kuo and Chen (1987) that reported the nascent formation of the information society in Singapore till the 1980s. It also makes an assessment of the role of proactive government policies in directing industrial restructuring and occupational changes in this city-state. It is found that the long-term growing trend in information-related occupations has been in tandem and supportive of industrial changes in Singapore. One more wave of growth of information producers (and certainly, innovators) and information distributors is expected in the next couple of decades. The momentum has started, and competition from regional countries similarly aspiring to be information and knowledge economies will quicken the pace. The government has initiated fundamental changes in the educational system to meet the challenges of the knowledge-based economy. The small city-state has also long adopted an adaptive philosophy to be responsive to the ever-changing environment, either in technology or in regional politics. Based on the trend analysis, it is expected that the emergent information society will graduate into full status when Singapore attains a developed country status in the forthcoming decades.

浅谈季布故事的变更与发展——兼论《捉季布传文》对《史记》中季布故事的拓展

敦煌本《捉季布传文》的故事原型来自《史记》、《汉书》中的季布故事,由于时代的变更,社会的发展,文体文风以及受众视角的转变,使得季布故事在流传中不断加以丰富,至唐代敦煌变文其情节更加完善,人物更加丰满,不仅一改汉代史传文学简略质朴的叙事风格,而且整体变化尤为明显。探讨《捉季布传文》对《史记》中季布故事的拓展,进而探究唐代俗文学的创作视角。     

Evaluating the effects of programs for reducing achievement gaps: a case study in Taiwan

Considering that achievement gaps have become a serious educational problem worldwide, the Ministry of Education in Taiwan has been addressing a series of policies to reduce achievement gaps, but the effect of these policies has not yet been carefully examined. Therefore, the present study investigated current educational policies, achievement gap phenomenon, and its changing trends in the use of national standardized tests in Taiwan and evaluated the degree to which these policies are reducing the achievement gaps among Taiwanese students. Junior high school graduates who took the high school entrance examination between 2004 and 2010 were recruited to examine the associations between their academic achievements and variables such as socioeconomic status (SES), ethnicity, and school district. Time series analyses were conducted to determine the longitudinal trends for the achievement gaps. The results revealed that achievement gaps are decreasing among different ethnicities, but they are increasing among different SESs and school districts. These findings demonstrate some positive effects of the educational policies introduced in Taiwan, but also the need for further modification and precise implementation of these policies. Suggestions for implementing educational programs and policies to reduce achievement gaps are also presented.     

Implementing web 2.0 tools in the classroom: Four teachers’ accounts

In this paper, four teachers shared their experiences using the following free Web 2.0 tools with their students: Jing, Wix, Google Sites, and Blogger. The teachers found that students reacted positively to lessons in which these tools were used, and also noted improvements they could make when using them in the future.
