This thesis persists on the idea of scientific development and the guiding ideology of constructing harmonious schools. Unifying the actual problems in the school administration, it defines the Basic concepts of technology, curriculum, organization, and school knowledge Management strategy by using the correlative research results; it discusses the theoretical background and the practical foundation of SKM, and then concludes the three kinds of strategic localizations of SKM, namely technological innovation and resource-sharing, knowledge innovation and curriculum development, as well as organization innovation and core competition; the deduction shows that the strategy choice of SKM is rich but united; this thesis draws attention to construct and analyze the strategy frame system of SKM, which integrates technology, curriculum and organization; it intends to construct a learning-researching-innovative school as the SKM mechanism. Finally, a brief exposition of the school knowledge Management and assessment, designed to broaden the horizons of studying SKM and to be used as the references for the Basic path and the general direction to the SKM, has been proposed based on the comprehensive and integrated strategy.The main innovational spots in this thesis include that, first, the special study on the strategy for the knowledge management in school (SKM) will be helpful for the school administrators to grasp the working points of SKM macroscopically, and, secondly, the strict and complete frame analysis, which for the first time integrates technology, curriculum and organization into the SKM, will be helpful for the staffs in a school to concert their efforts omni-directionally and corporately so that they can implement the knowledge management effectively and successfully.

Construction of the Artificial Nature of Technical Ecological Perspective (Education Papers posted on November 28th, 2014 )

The task of science is to understand the world, the task of technology is altering the world, the scientific understanding of the endless, while the technology as the means of altering the world, must be the guide in order to gain and avoid loss of the value of rational. What kind of technology there is what kind of artificial natural, artificial nature by the profound impact of technology, technology eco-transformation or not ecological artificial determinants of success or failure of the natural construction. With the technical nature of the laws of natural development, which means that the natural, but the technology also has the nature of the intervention, anti-natural characteristic.Technology development and innovation, the laws of nature provide a direction to a certain extent, determine how technology development. The natural law of development of technology, to promote the development of Social, ecological harmony, native nature well protected, is clearly conducive to the sound development of the entire ecological chain. Artificial natural living material conditions of human beings needed, also improved with the development of artificial nature, the human cognitive ability and practical level, the subjective initiative means that people have the ability to transform the artificial nature, if the improper use of technology, it will cause a negative effect on the artificial nature of the substances derived from natural substances, the purpose of requirements can be achieved only follow the laws of nature on the basis of the artificial nature is essentially to change the native nature objects.In the process of change in the natural substances, reflecting the penetration of the technology. The technical regulations the characteristic, structure and function of the artificial nature. Technical result due to its wide range and irrational application of the ecological balance of intervention and even more than nature itself has self-healing and self-regulating capacity, anti-natural is expanded beyond the technical controllability negative factors, which caused more than its self-purification capacity of natural systems to some extent, this imbalance had a significant impact to the development of human society, leading to a series of adverse consequences. In order to promote artificial natural Health and development, human beings must change the values of technology, to accomplish ecology-oriented that based on long-term vision to establish the development strategy of the artificial natural, to come true artificial natural development model ecological turn.Divided into five chapters, the first chapter of this thesis is the introduction to explain the purpose and significance of the artificial nature suggested that the artificial nature study, domestic and abroad on the artificial nature of the the present situation. The chapter two is technology and technical ecology, mainly elaborated technology combined natural and unnatural the necessity and feasibility of the technology ecosystem. Third chapter is connotation of the artificial nature and technology dialectical relationship, starting from the artificial nature of meaning, form, features a brief analysis of the artificial nature, combined with the artificial nature and nativel nature of the relationship, indicating the need for the sustainable development of the artificial nature characteristic. In the process of change due to native nature substances, highlight the role of technology, and then demonstrate the penetration of the artificial natural, the artificial nature and technology dialectical relationship. The chapter four is involve evaluation and reflection of the artificial natural development, in the evaluation aspect, elaborate the artificial nature development about practical significance and impact of the environment, in the reflect aspect, elaborate the technical alienation with native nature and expound artificial nature difficult to adapt with each other. The chapter five is Artificial Nature construction of technology ecological context with the ecological technology eco-transformation, the establishment of the eco-artificial natural direction.

Study of Fertilizer Effect and Compound Technology of Biomass Gasification ASH (Education Papers posted on November 28th, 2014 )

ABSTRACT It is not dividual that energy exploitation and environment protection. China is one of the biggest countries on producing and consuming energy resource, and it is also one of the badly polluted countries.In recent years,people have perceived the threat and effect with the circumstance exacerbate,they begin to pay attention to atmosphere quality and entironment.To protect the environment is very important energy tactic.The environment factor will be significantly constrained by energy development.With biomass gasification power generation technologies mature and the size of the project generating growing,biomass gasification ash utilization of the resources become a hotspot on the biomass field.Biomass gasification ash is outgrowth of the biomass gasification for power generation,The kalium in the straw is all salts in the form of ash in the gasification process.it is about above 1.0%,some can overtop 10%,and 80~90%is water-solubility kalium,it is easy to absorb by crop,it also contain N、P、Ca、Zn、Mu、Mg etc.Using the biomass gasification ash to produce compound fertilizer,the products both have N、P、K and organic compound and microelement,it is propitious to crop grow and improve utilization rate.Using the biomass gasification ash to manufacture compound fertilizer,it is not only abate the status that short of kalium but also can implement biomass gasification ash utilization of the resources and protecting the ecological environment has important practical significanceThis article is under the support that the 863 national projects “biomass gasification for power generation and optimization system demonstration projects” (the serial number:2003AA514010),we do the research on major component characteristics、fertilizer effect and technology of biomass gasification ash through the experiment.The main contents and conclusions are as follows:(1)In the paddies ash,kalium is 2.14%,phosphor is 0.24%.(2)According to fertilizer effect experiment of biomass gasification ash,the experimental results indicate:under the same nutrition conditions,biomass gasification ash compares with the fertilizer:the gemmiparous time is earlier than the time of the fertilizer except the cucumber;late growing significantly better than the latter,the laminae is thick and lustrous;at the course of growing the former has not insect pest but the latter has;growing is better than single fertilizer when add nitrogen and phosphor to biomass gasification ash.(3)Produce compound fertilizer can adopt disc granulation technology,the experimental results indicate:design the direction for producing fertilizer is 15-6-9,by testing the result is 14.60-6.10-10.02,granularity is 95.8%,the aquiferous quantity is 4.7%,these are eligible basically.(4)In the biomass gasification ash compound fertilizer cucumbers grow better than common compound fertilizer,as the height,the breadth and length of lamina,it is not dividual that it has microelement as Ca、B、Zn etc.In the biomass gasification ash,they can accelerate cucumber grows;otherwise,we can observe which does not artifactitious biomass gasification ash fertilizer grows better than biomass gasification ash compound fertilizer,it has the phenomena that fertilizer effect balance out.(5)Benefit analyse:the results show that net present value(NPV)is 22306.95 Yuan,and static pay back period is 7.67 year,internal rate of return(IRR)is 10.1%.

The Analysis on Risk in the Process of Nature Transferring to Artificial Nature (Education Papers posted on November 7th, 2014 )

One manifestation of human progress is the transformation from nature to artificial nature, through which technology plays the important roles of driving force. However, the development of technology, especially the development of modern technology, brings all types of risks to human being as it pushes forward the formation and progress of artificial nature as well as promote the living conditions. These risks are derived from every steps of technological process and pose a threat to the daily life and living of human beings. Suggestions on how to avoid and overcome such risks and analyze its origin from the perspective of Philosophy of technology is needed.Based on the theory of artificial nature, theory of technological process and relevant theories about risks, this paper focuses on the essence, origin and classification of risk during the transformation process from nature to artificial nature and analyzes them. The paper analyzes the origin of all risks have been illustrated and classifies ten common risks in practice. Further more, the paper explores the theoretical foundations and means which used to avoid and overcome risks from the perspective of theory of Philosophy of technology and theory of artificial nature. In special, the solutions to different types of risks have been introduced. In the analysis of three kinds of risks, the analytical method, strategy and analytical process have been introduced taken the cases of Wenchuan earthquake, SARS, influenza A (H1N1) and global crisis of 2008.In addition, the origin and demonstration of risks as well as the basis and means for risks avoidance have also been discussed.This article holds that to avoid and overcome the risk, we should at first start from the technology itself, find the root causes of the risk and give the right solution. At the same time, we should also explore the links between micro-technology nodes on the process of macro-technology combined with the actual situation of different regions. The grasp of the dynamics characteristics of technology, the Social attribute of technology, should be considered and paid attention to. In addition, comprehensive and effective technical assessment and forecast should be carried out, so to achieve optimally resolved of riskt.

A Study of William Gibson’s Matrix Trilogy in the Light of Cyborg Theory (Education Papers posted on November 5th, 2014 )

With the progress of science and technology, great changes have taken place in people’s life and even on themselves, and the science fictions that tend to predict the future tendency of society begin to draw more and more people’s attention. Cyberpunk is a contemporary science fiction genre noted for its focus on‘high tech and low life’. It gives prominence to advanced science, such as information technology and cybernetics. William Gibson, one of the primary representatives of cyberpunk, is called father of Cyberpunk movement because of his great contribution in successfully creating the conception of cyberspace, an informationized virtual online world. William Gibson’s‘Sprawl Trilogy’are famous early cyberpunk novels which can be seen as prominent examples of the cyberpunk style and theme. With technology as one of its most distinctive features, cyberpunk novels reveal the changes of human body and the expansion of space brought about by the application of high-tech, which corresponds closely with Haraway’s cyborg theory. Donna Haraway is a famous theorist who has had a deep study of the body, gender and identity issues caused by new technology. Donna Haraway defines”Cyborg”as”a cybernetic organism, a hybrid of machine and organism, a creature of Social reality as well as a creature of fiction.”She also emphasizes that the cyborg myth is about transgressed boundaries, potent fusions, and dangerous possibilities. This paper researches the people’s changes brought about by high-tech in William Gibson’s‘Sprawl Trilogy’in the light of Haraway’s Cyborg theory.This paper is constituted by the introduction, the body and the conclusion.In the part of introduction, the focus will be on the brief introduction of William Gibson and his‘Sprawl Trilogy’, Haraway’s cyborg theory, the previous studies on Gibson’s‘Sprawl Trilogy’, the research method and the research purpose.The main body of this paper consists of three chapters. In the first chapter, the exterior reform of human body brought about by the application of high-tech is analyzed. The author first adduces some cyborg images that are exteriorly reformed in Gibson’s novels and divided them into three kinds, the combination of man and Computer, Mechanical aids, and AI. The author then points out that these images are also cyborgs that are hybrids of machine and organism according to Haraway’s Cyborg theory, and specifies that their generation manifests the boundary breakdown between organism and machine.In the second chapter, this paper studies the inner changes of human body of the characters in Gibson’s‘Sprawl Trilogy’, that is, the genetically modified people. In addition to the Mechanical cyborgs in Gibson’s novels, there are also genetically modified characters. The author exhibits this kind of innerly changed cyborgs from two aspects, the genetically modified men and clone men. These kinds of creatures possess both the features of natural men and artificial men, while you can’t decide definitely which kind they belong to. These creatures of transgressed boundaries and potent fusions are cyborgs. The author then demonstrates that the innerly changed creatures possess the feature of the transgressed boundaries between natural and artificial.In the third chapter, the paper gives a careful analysis of the spatial turning. The cyberspace, another space besides people’s living space, is a virtual world existed in Computer networks. As cyberspace is the most significant feature in Gibson’s novels, the author then gives a detailed description of the generation and features of cyberspace. Through the analyzing of the cyberspace in Gibson’s novels, the author then discusses that the generation of cyberspace has obviously blurred the boundary between virtual and reality.In the part of conclusion, this paper points out that William Gibson succeeds in shaping various kinds of cyborg images which challenges the dualisms because of their features of transgressed boundaries and potent fusions. Gibson in his novels not only predicts a highly advanced world full of cyborgs but also attempts to arouse people’s reflection on the influences of science and technology.

On Hume’s View of Technology (Education Papers posted on October 27th, 2014 )

Hume was a famous British agnostic philosopher and ethicist in the 18th century, and also was well known as a historian and economist. He was one of the most important people during the Enlightenment in Scottish and in the history of Western Philosophy. Because of Hume’s outstanding contribution to Philosophy, the focus of many previous studies of Hume was his philosophy, especially epistemology, rather than his view of technology. In fact, Hume also had his own amazing insights on ethics, religion, philosophy of technology and other fields. In the early time of modern society, where Hume lived, which had a set of great and important changes, the understanding of technology confronted the change from tradition to modern. The contradictions, which connected with each other in Hume’s ideological system, showed several Social realistic conflicts. In particular, the reforms of politics, economy and culture, the optimistic utilitarianism of controlling and conquering nature through technological ways advocated during the Renaissance and, the thoughts of subject-object dichotomy based on man and nature from Bacon, Locke and Hobbes all had a significant impact on Hume’s view of technology, especially the nature and role of technology.Both the understanding of technology in ancient Greece and the prototype of modern philosophy of technology can be discovered in Hume’s view of technology. Therefore, the study of Hume’s view of technology is an enormous task which has pretty good significance in theory and reality. This findings demonstrate that the internal reasons and contradictions of generation and evolution of Philosophy of Technology during certain historical period. And it not only enriches the research methods, but promotes the diversification of the current studies in Philosophy of Technology. In the meanwhile, it helps to form a better understanding of technology.In this paper, we present a method which combines cases study with system study to conduct a comprehensive and systematic study of Hume’s view of Technology. This approach adheres to the principle of combining main points with non-main points, combining historicism with objectivist. As a typical of agnostic, Hume denied the knowability of the nature and law of objective things. And as a world-known empiricist, he stressed the importance of experience, and acknowledged that the human activities were legitimate within experience, and technology is reasonable within empiricism, and he emphasized that technology derived from experience rather than innate sense. Hume argued from the perspective of logical positivism that technology is the unity of the means and ends, also is the tool for the pursuit of human happiness. On the relationship between technology and nature, he believed that artifacts were essentially different from natural things and, artifacts could not achieve the perfection of the natural. In the standpoint of utilitarian, technology played a very important role in national economy, culture and politics. It can combine nation, commercial trade, manufacturing and humanity with each other perfectly together. Hume also had the attitude worried about technology while he praised its huge functions. So his attitude toward technology is hesitant rather than purely utilitarian. Hume’s view of technology is unique and distinctive in the history of the industrial development. The purpose of this paper is to analyze Hume’s view of technology, revealing its rich content and he important value of nexus role in the history of philosophy.

Analysing Ecological Character of Technology (Education Papers posted on October 12th, 2014 )

The analysis on the ecological character of technology may avoid one-sided understanding of technology. These one-sided understandings of technology and non-rational application have a serious impact on the coordinated development between man and nature. Faced with this problem, we need to introduce ecological theory and system theory into the analysis of technology. In order we analyze and construct technical system by simulating sophisticated construction and harmonious functions of natural ecosystems to avoid the conflict between technical application and mechanism of the natural ecosystem.The analysis on the ecological character of technology is to use the method that draw an analogy between natural system and technical system to analyze the ecological character of technology. ecosystem is a very broad inclusive concept; it is not only limited to natural ecological systems, but also including Social ecosystem and technology ecosystem which is more broad understanding of it. In the Social ecosystem,technology is in the changing process, and always interact with the surrounding politics, economy, and culture to build social ecosystem together, which is similar to the life in the natural ecosystem. Technology exist in the form of the system, it is the same as the natural ecosystems that is open, holistic, hierarchical, self-organizing system. In addition, the technology itself is in the concrescence, the cycle of life about technology to create the technical ecosystem. There is diversity of “technical species”in the technical ecosystem. These “technical species” interact with the surrounding environment. This interaction is similar to the mechanism of evolution, and symbiotic mechanism, the mechanism of genetic variation in the natural ecosystem .These mechanism make the Re-cycle mechanism come true.For analyzing on the ecological character of technology, it is necessary to study the various components of technology and the relations between technology and technical environment from the systematic, the integrated perspective. We should regard the functioning of natural ecosystems as an important source of guiding technological ecological research. Humankinds need to turn their own Mechanical technological view to an ecological technological view gradually, in order to achieve the transformation from Mechanical technologies to ecological technologies.

Course assessment practices and student learning strategies in online college courses (Education Papers posted on March 27th, 2013 )

This study explored assessment practices in online courses and the relationship between assessment and student learning strategies. Assessment practices are important in determining what kind of learning occurs in a course, and online learning environments by their very nature lend themselves towards different assessment practices. However, little is known about online assessment practices or their influence on student learning strategies. The study used a mixed-method, two-phase design. In Phase I, 60 online community college courses were sampled across disciplines. Instructor and student surveys and course observations were used to describe the status of course assessment practices and student learning strategies and explore which assessment practices relate to which learning strategies. In Phase II, follow up qualitative investigations of nine courses explored how certain assessment practices influence critical thinking strategies. The assessment practices in these online courses appear to match in many areas what is considered best practice in summative and formative assessment. Using multiple assessments and methods, grading student learning over time, and providing frequent and individualized feedback to students are beneficial practices. Both students and instructors seem to focus their efforts on elaboration, critical thinking, and self-regulation strategies, more than rehearsal and organization strategies. However, there are potential areas for improvement, such as using multiple assessors more effectively, adding only an appropriate number of assignments, and ensuring students utilize the frequent feedback they receive. Quantitative and qualitative data both indicated that discussions, written assignments, and papers were positively related to critical thinking strategy use whereas final/midterms and non-graded assignments were negatively related. Assignments that were successful in encouraging critical thinking had three areas in common: providing explicit intent to promote critical thinking, allowing time for reflective thinking, and using appropriate instructor guidance. In online discussions that promoted critical thinking, instructor postings were less frequent, more neutral, and used provoking questions. Knowledge retention multiple-choice questions were least useful for understanding student learning and played a formative instead of summative role. This study suggests that assessment methods are most important in determining the type of learning occurring and grading opportunities are ideal teachable moments in online courses.

The impact of teacher self efficacy and attitudes toward classroom computers(s) on the use of classroom technology (Education Papers posted on March 27th, 2013 )

This study focused on examining the integration of computers) into classrooms of schools in an urban school district. Teachers in the district had access to a laptop or desktop computers) for use in their classrooms. Teachers also had access to remote Internet access dial up) and web-based professional development at home or at school. Three instruments were used in this study: Teachers Computer Attitudes, developed specifically for this study, Teachers Sense of Efficacy Scale-Short Form Tschannen-Moran & Wollfolk, Hoy), and a demographic survey developed specifically for this study. Results of this study provided support that teacher efficacy was significantly related to teachers attitudes toward computers) for best practices, Computer usefulness, and computer efficacy. The negative relationships between teacher efficacy and computer anxiety support the contention that teachers who had higher levels of confidence were less anxious about using computers) in their teaching practice. Teachers who lacked sufficient confidence in using computers) in their work were likely to avoid them altogether. The positive relationships between teacher efficacy and computer efficacy support the lack of anxiety. Perhaps computers) have been common in the classroom and teachers may be receiving sufficient training to encourage them to be used effectively. The teachers in the present study indicated that they used computers) for a variety of classroom tasks e.g., lesson planning, drill and practice, grading, Education, classroom Management and presentations) and were familiar with sever types of productivity software word processing, grade books, educational games, presentations, etc.). Teachers who recognize the value of computer use in their classroom are more likely to have higher levels of teacher efficacy. Teachers attitudes toward computers) were not related to their self-reported skills with computers). Although this question had not been addressed in previous literature, teachers who self-reported their skills as excellent or good were thought to have more positive attitudes toward the use of computers) in their classrooms. An interesting finding was the negative relationship between teachers person use of computers) and computer anxiety. Teachers who expressed higher levels of anxiety were less likely to use computers) for personal use.

The impact of individual learner characteristics and synchronous computer-mediated communication on language production in learners of English (Education Papers posted on March 27th, 2013 )

As Computer technology advances rapidly in the past decades, incorporating Computer technology into classroom teaching has been popular, especially in the area of foreign language Education because of its potential benefits. Among Computer technology, computer mediated communication henceforth, CMC) is widely used in language classrooms for its benefits, for example, more equal participation, a less stressful learning environment, and increased output Chun, 1998; Kern, 1995; Warschauer, 1996). In addition, due to the hybrid nature of CMC, learners are allowed to have more time to process input, monitor and edit output Kelm, 1992; Warschauer, 1996) resulting in more accurate and complex language production compared to face-to-face conversation. Beauvois, 1992, 1995; Kern, 1995; Pellettieri, 2000; Sotillo, 2000; Warschauer, 1995, 1996). Several studies examined another benefits of CMC – the development of oral proficiency Abrams, 2003; Beauvois, 1998b; Payne & Whitney, 2002; Kost, 2004); however, the results of these studies are consistent, suggesting that oral proficiency may be enhanced by synchronous online discussion. Instead of investigating whether synchronous CMC is beneficial for all students, the present study aims to investigate the extent to which the factors such as personality types, amount of participation and previous experience using chat contribute most to the development of oral skills. That is, the present study focuses on individual, affective variables that could affect the effects of CMC on spoken language development among beginning learners of English. Employing a pre and post one-group comparison design, 16 students participated in the study and their oral skills were measure by two interviews and the interviews were scored by a native speaker informant and the researcher based on the scoring rubric that was adopted from the previous study Payne & Whitney, 2002). The results of repeated measures ANOVA revealed none of factors identified in the study were statistically significant. The results, however, should be interpreted that the use of CMC in language classroom does not disservice any group of students with a specific personality type or previous experience using chat. With numerous benefits known, chatting remains a valuable pedagogical tool to promote second language learning.
