中国古代职业技术教育之方法

艺徒训练制贯穿中国古代职业教育历史进程，无论是世承制、官工作坊制，还是官工业制、民间师承制，都倡导或坚持了技艺、规范和就业道德融为一体，注重示范与模仿、总结与交流。案例教育方法不仅体现在职医、职官教育之中，也体现在吏员训练和艺徒训练等方面。算学教育渗透于天文历算、冶炼铸造、纺织制器、赋税徭役、商贾买卖等职业技术教育之中，坚持联系生产、生活实际于始终。     

Triadic interaction in clinical task-based interviews with mathematics teachers

A clinical task-based interview can be seen as a situation where the interviewer–interviewee interaction on a task is regulated by a system of explicit and implicit norms, values, and rules. This paper describes how documenting and mapping triadic interaction among the interviewer, the interviewee, and the knowledge negotiated can be used to increase procedural replicability of the interview and accuracy of drawn conclusions about the interviewee’s thinking process. Excerpts from interviews with 25 inservice mathematics teachers working on a task to make up a problem whose solution requires division of two fractions are discussed. The excerpts illustrate the relationship between methodological decisions taken by the interviewer during the interview and the applicability of the interview output to the research questions. A divergent analysis of the interviews with these teachers, which spanned over two years and were conducted by four interviewers, is used to offer a framework for analyzing data collected in clinical task-based interviews.     

Giving Education a Bad Name: Bookish Boys in Contemporary American School Stories

This article discusses contemporary American school stories that appear to advocate learning and literacy as a democratic good, but actually undermine democratic possibilities by teaching young readers to think of academic inquiry as a means to selfish, petty ends. Since “learning” and “literacy” are catchwords for educators dedicated to remedying neoliberal inequities, it is understandable why authors of school fiction such as Andrew Clements and Tommy Greenwald are celebrated by educators for foregrounding the exploits of bookish characters. Yet, as is shown, the narrative arcs in works such as Frindle by Clements and Charlie Joe Jackson’s Guide to Not Reading by Greenwald ultimately endorse the market consciousness, deregulation, and excessive individualism for which neoliberalism is known. Examining the ways in which these two novels intersect with ongoing debates over literacy standards, learning outcomes, and academic honesty, it is argued that the didactic-pedagogical imagination in contemporary American fiction for young people has a biased conception of student development and life preparedness, ideologically at odds with democratic curriculum provision.     

Visualization of structured packing with laser induced fluorescence technique: Two-dimensional measurement of liquid concentration distribution

A method of using laser induced fluorescence(LIF)technique was applied to two-dimensional measurement of the liquid concentration distribution in the 250Y structured packing sheet. The experimental structured packing sheet was made of perspex so that the laser could pass through it. The visualization of the distribution of the liquid concentration in the structured packing sheet was realized. The calibration of the thickness and liquid concentration was carried out firstly and the regression formula I=kcd was acquired, in which concentration c and the liquid film thickness d were both considered. Then the liquid feed of uniform tracer(rhodamine)concentration entered the perspex structured packing from the top under different spraying densities. The corresponding thickness of liquid film on the packing was calculated. Finally, tracer(rhodamine)with a high concentration was injected only at one fixed point of the structured packing under different spraying densities of the liquid. With the known liquid film thickness, the concentration distribution of the tracer can be calculated inside the structured packing sheet.

紫外分光光度法测定莽草酸的解离常数

根据光度法测定酸解离常数的原理,采用紫外分光光度法测定了莽草酸的解离常数。在选定波长(215、220、224、226、230 nm)处测定不同pH值的莽草酸溶液吸光度值,得到莽草酸的离解常数为3.87±0.08。方法简便,结果可靠。     

教育组织现象学范式的哲学基础

教育组织现象学范式是一种有着重要影响的主观范式论,这种范式关注组织中人的存在,强调组织的可理解性与组织的建构性,认为组织是人的意志与价值的体现。古代哲学、德国古典哲学、现象学与存在主义、历史主义以及后现代主义等哲学思想都影响着这种范式的产生与发展。建立在这些哲学思想的基础之上,教育组织现象学范式对实证主义、理性主义以及结构功能主义展开批判,并构建出人本性、道德性与理解性的全新组织观。     

Study on pig growth hormone gene polymorphisms in western meat-type breeds and Chinese local breeds

Chinese Meishan and Jiangquhai pigs are two of the most prolific pigs in the world, but their growth rate is lower than that of Duroc, Landrace and Pietrain pigs. It is suggested that growth rate is regulated by growth hormone. The objective of the current study was to analyze the porcine growth hormone (pGH) gene polymorphisms based on the polymerase chain reaction restriction fragment-length polymorphism method (PCR-RFLP) for three western meat-type breeds (Duroc, Landrace and Pietrain) and two local Chinese pigs (Meishan and Jiangquhai). Five polymorphic restriction sites were detected with the ApaI, MspI, BspI and HhaI restriction enzymes in two amplified fragments (605 bp, -119 to +486; 506 bp, +206 to +711). Breed difference was found only in the 506 bp fragment. There was no difference in allelic frequencies of BspI and HhaI restriction sites among the five breeds (P>0.05). Landrace and Meishan pigs lacked allele G3 of MspI site. The allele G3 frequency of restriction MspI site of the 506 bp fragment in Pietrain pigs was higher than that in Duroc and Jianquhai pigs (P<0.001). For ApaI site, the Meishan pigs lacked allele G1; no difference was found in allelic frequencies among Pietrain, Duroc, Landrace and Jiangquhai pigs (P>0.05). This new and rapid PCR-RFLP typing method is an attractive tool for analysis of porcine growth hormone gene restriction sites. The differences in MspI and ApaI restriction sites may explain the growth difference between the foreign meat-type breeds above mentioned and local Chinese pigs.     

对初中历史新课程的思考

我市从2002年秋季进入初中新课程，至今已历时4年。这几年，我们采取先市区、后县城、再农村，边实验边推广的方式，经历了逐渐适应、摸索经验、学习模仿和再创新的过程。总结和反思初中历史新课程的教学，有很多体会，写出来可能有点滴参考价值，也希望得到专家和同行们的指导。
