Constructing a Community Response Grid (CRG): The Dublin, Ohio Case Study

Freund, John 01 January 2012 (has links)
During an emergency, information availability is critical to preserving life and minimizing damages. During the emergency response, however, information may not be available to those who need it. A community response grid (CRG) can help ameliorate this lack of availability by allowing people to document and distribute emergency information to professional emergency responders (PERs). A CRG combines mobile communications services, Internet technologies, e-government applications, and social network concepts with traditional emergency response systems. The problem that this case study investigated was how to construct a CRG for the City of Dublin, Ohio, Division of Police that works in conjunction with an in-place emergency management system (EMS). The goal was to create a process that is replicable by similarly sized cities that wished to implement a CRG. In this investigation, the author examined CRG design and implementation issues such as message origin, training needs, policy design, security issues, and funding. The results of this investigation were organized in terms of Systems Development Lifecycle (SDLC) phases. Throughout these phases, the author identified information that can aid PERs in to better implement a CRG. Based on the results, the author developed a paradigm for constructing a CRG that meets the requirements of residents of the City of Dublin, Ohio, Division of Police and of similarly sized municipalities.

陳新豐 Unknown Date (has links)
論文名稱:線上題庫與適性測驗整合系統之發展研究 頁數:337 校所系別:國立政治大學教育學系 畢業時間及摘要別:九十學年度第二學期博士論文摘要 指導教授:林邦傑博士、余民寧博士 研究生:陳新豐 論文摘要內容 本研究係結合工具研發、理論驗證與效能評估的研究,旨在開發一個建構在全球資訊網的「線上題庫與適性測驗整合系統」,以提供教師在網際網路環境下的輔助教學評量系統,除了可動態新增題庫之外,並能針對學生提供童身訂做的適性測驗。因此,研究的兩個核心主軸為「線上題庫與適性測驗整合系統」之開發與「線上題庫建置」的理論驗證。 依循這兩個核心主軸,本研究的研究目的有三:(一)開發線上題庫與適性測驗整合系統。(二)驗證建置題庫的相關理論。(三)評估整合系統運作效能與使用者滿意程度。 為達成這三個研究目的,研究者採用結構分析中,Sehlly、Cashmen和Rosenblatt (2001)所提出的「系統開發生命週期」,將「線上題庫與適性測驗整合系統」開發過程分為「系統規劃」、「系統分析」、「系統設計」、「系統建置」、「系統運行與支援」等五個階段逐步開發。 研究樣本方面,第一次預試選用台南市崇明國中三年級學生115人,第二次預試選用台南市建興國中三年級學生191人,正式施測樣本則是台灣地區北、中、南、東、離島等共計九校2567位國中三年級學生為研究對象。此外,在需求調查報告部分,共調查十五位專家對開發系統的意見。 就研究工具來說,本研究主要研究工具為「線上題庫與適性測驗之整合系統」,另外,「功能需求調查問卷」、「硬體設備」、「軟體工具」、「系統評估量表」也是本研究的研究工具。 就資料處理來說,本研究運用ITEMAN、BILOG、MatLab和SPSS套裝軟體進行資料處理,所採用的統計方法包含古典測驗理論與試題反應理論等理論來分析,計有試題分析、IRT三參數估計、因素結構分析等。 研究結果部分,本研究得到如下結論:(一)線上題庫與通性測驗兩個系統可整合為一。(二)線上題庫與遍性測驗之整合系統具有多項功能。(三)結構化分析中之系統開發生命週期是開發整合系統的理想方法。(四)題庫等化轉換常數方法以Mean/Mean和Haebara等方法較佳。(五)線上測驗與紙筆測驗的試題訊息量相近,但難度偏高。(六)線上測驗連結效益良好。(七)本整合系統運作效能良好。(八)使用者對整合系統之功能感到滿意。根據研究結論,本研究針對工具研發、題庫建置、效能評估等提出具體建議。 關鍵字:試題反應理論、題庫、等化、電腦化適性測驗、系統開發生命週期 / A Reserach In The Development of An Integrated On-Line Item Bank and Computerized Adaptive Testing System Abstract This research is to develop an integrated internet system of on-line item bank and computerized adaptive testing (the "System"), which is comprised of the teaching tool development, theory verification, and efficiency evaluation. Except for the addition of new item bank dynamically, the System, an auxiliary teaching evaluation system for teachers, can also provide customarily made adaptive testing for students. Therefore, to develop an integrated on-line item bank and computerized adaptive testing system and to verify the theory of on-line item bank development constitute the two core spindles of this research. Following the aforementioned research spindles, the main purposes of this research are going to: (A). Develop an integrated on-line item bank and computerized adaptive testing system. (B). Verify the related theories concerning the development of on-line item bank. (C). Evaluate the operating efficiency of such System and the degree of users' satisfaction. The "systems development life cycle" (Sehily, Cashmen Rosenblatt, 2001), a structured analysis method, is adopted to conduct the research. The development process of an integrated on-line item bank and computerized adaptive testing system is divided into 5 separate and successive stages, starting from system planning, system analysis, system design, system development, to system operation and support. In terms of research sampling, the selected samples in the first preliminary testing are 115 ninth-grade students of Chiung-Ming High School in Tainan City, Taiwan. The selected samples in the second preliminary testing are 191 ninth-grade students of Cheng-Sing High School in Tainan City, Taiwan. The third and official sampling is 2,567 ninth-grade students who were selected from a total of 9 high schools ranging from Northern, Central, Southern, and Eastern Taiwan, and islands adjacent to Taiwan. Furthermore, in the demand side, an investigation has been conducted to consult with 15 teaching experts for their professional opinions in regard to such System development. As far as research tools are concerned, except for the main research tool - the integrated on-line item bank and computerized adaptive testing system, other research tools employed consist of functional demand questionnaires, hardware equipments, software tools, and scales for system evaluation. In the aspect of data processing, ITEMAN, BILOQ MatLab, and SPSSapplication softwares are used to perform the data processing. The statistical method,like classical true score theory and item response theory and etc., is applied to conduct the following analyses: item analysis, IRT three-parameter estimate, structured analysis of elements, and etc. The results of this research lead to the following conclusion: 1. The on-line item bank: system and the adaptive testing system, the two separate systems, can be integrated into one system. 2. The integrated on-line item bank and adaptive testing system can play multiple functions. 3. "Systems development life cycle" in the structured analysis is an ideal manner to develop an integrated system. 4. "Mean/Mean", "Haebara" and, etc. are the better methods to perform the item bank equating and constant conversion. 5. For users, the information volume provided by on-line testing and traditional written testing are quite similar, but the degree of difficulty of on-line testing is higher than that of traditional written testing. 6. The linking effect of on-line testing is fair. 7. The operating efficiency of the integrated system is fair. 8. Users are satisfied with the functions of the integrated system. Based on research conclusions drawn thereon, suggestions for tool development, item bank development, and efficiency evaluation are also provided. Keywords: item response theory, item bank, equating, computerized adaptive testing,systems development life cycle
