【正文】 畢 業 設 計 說 明 書基于 WEB的在線自測系統的設計與實現基于WEB的在線自測系統的設計與實現摘 要：計算機應用技術的日益發展，為教育技術學的研究與發展帶來了新的機遇，如何把計算機和網絡更有效地引進教育領域為教育服務，已成為教育領域中的一個新的課題。隨著網絡應用的多元化與普及化，學生學習的途徑更加多樣化。通過網絡，學生可以更好的完成對所學知識的鞏固和理解，同時通過在線自測系統，可以在網上對所學內容進行自我測試，清醒的認識自己的學習情況，發現不足，以便更好的完成學習任務。在線自測系統可以配合多元化教育，對學習效果直接進行考察并自動組卷、自動判卷。根據成績庫學生可以很直觀的看到自測練習的成績，以便了解自己近期的學習效果，有利于學生的自學。本文主要闡述了基于 WEB 技術的在線自測系統的體系結構和具體設計以及實現過程。介紹了在線自測系統中對題庫的管理、試卷的管理、學生成績的查詢，在線自測功能的實現以及用戶權限的管理和試卷發布等功能。著重介紹了組卷功能、時間控制功能、自動批改試卷功能的設計與實現。整個系統層次結構簡單，操作容易，并具備一定的安全性，使用該系統能更高效、便捷地檢驗學生在課程學習中的學習效果。關鍵詞: 在線自測；時間控制；試題庫1The Design and Implementation of Online Selftest System Based on WEBAbstract : The increasing development of puter application technology for educational research and development has brought new opportunities, and how the puter and work to be more effectively to introduce the field of education, has bee a new topic. With the diversity of work applications and the popularity of more diverse ways of learning. Students can better plete the consolidation of the knowledge and understanding, through online selftest system, you can learn online content on the selftest, a clear understanding of their own learning and found weaknesses in order to better pletion of learning tasks. Online selftest system can acmodate the diversity of education, direct effects on learning and automatic generation of inspection, automatic graders. According to results library students can see the selftest exercises very intuitive results, in order to understand their recent learning, helping students selflearning. This article focuses on technologybased WEBline selftest system architecture and detailed design and implementation process. Introduced an online selftest item bank system on the management, paper management, student achievement information, online selftest function of the realization and user rights management and publishing papers and so on. Test paper focuses on the function, time control function, automatic correcting function of the design and implementation papers. Hierarchy of the whole system is simple, easy, and have a certain security, to use the system more efficient and convenient to test students in the course of learning. Key words: Online self_test。Time control。 Test database基于 WEB 的在線自測系統的設計與實現目 錄1 概 述 ...............................................................................................................................1 項目開發背景及意義 ....................................................................................................1 系統開發環境 ................................................................................................................1 系統開發技術及工具 ....................................................................................................22 需求分析 ...........................................................................................................................5 系統可行性分析 ............................................................................................................5 系統基本需求 ................................................................................................................5 系統功能模塊需求 ........................................................................................................6 系統的設計目標 ............................................................................................................73 系統概要設計 ...................................................................................................................7 系統開發環境 ................................................................................................................7 數據庫 設計 ....................................................................................................................74 系統詳細設計 .................................................................................................................11 數據庫連接及操作類的編寫 .......................................................................................11 在線自測模塊設計 ......................................................................................................12 成績查詢模塊設計 ......................................................................................................16 查看正確答案模塊設計 ..............................................................................................17 試卷管理模塊設計 ......................................................................................................19 題庫管理模塊設計 ......................................................................................................23 管理員功能模塊設計 ..................................................................................................25 用戶登錄模塊設計 ......................................................................................................27 學生注冊模塊設計 ......................................................................................................295 系統測試 .........................................................................................................................30 題庫管理模塊測試 ......................................................................................................30 試卷管理模塊測試 ......................................................................................................31 在線自測模塊測試 ......................................................................................................326 結束語 .............................................................................................................................33參考文獻 .............................................................................................................................34致 謝 .............................................................................................................................35附 錄 ...................................................................................
