使用Vue框架與Spring Boot建置題庫管理及精熟檢定系統:以Oracle OCA SQL為例
為了解決SQL SELECT IF 的問題,作者劉軒齊 這樣論述:
精熟檢定(Mastery Test)已經被廣泛用於專業證照及執照考試,判斷受測者是否具備足夠的專業能力。在教學上,尤其針對證照導向的課程,教師透過精熟測檢定以瞭解學生是否已精熟特定主題,藉此可動態調整的教學進度。教師執行精熟檢定時,若以人工的方式執行一連串的題庫管理、編製試卷、製作解答卷等活動,將造成極大的教學負擔,進而影響教學成效。本研究以 Oracle OCA SQL 證照考試教學為案例,使用 Vue 與 Spring Boot 框架,開發一題庫管理及精熟檢定系統,以減輕教師執行精熟檢定之教學工作負擔。題庫管理功能上,命題者以 Markdown 格式編制試題內容及其圖片,之後可以批量匯入
題庫並進行維護。命題者也能對試題貼標籤進行試題分類。此外,命題者可透過Excel匯入試題的三個試題參數:鑑別度、難度和機運度(pseudo-chance),做為精熟檢定功能挑選試題的依據。在精熟檢定功能上,使用 Hambleton and De Gruijter (1983) 提出的測驗方法為基礎,在給予試題參數、檢定範圍及最小可接受之誤判率下,從題庫中選擇最少的試題數產生試題卷及解答卷,以進行精熟檢定。本研究開發之系統,提供教師一個題庫管理及精熟檢定測驗之工具,除了減輕教師教學負擔外,並能以更系統化的方式判斷學生學習精熟度。

書目探勘公共圖書館帕列托法則
為了解決SQL SELECT IF 的問題,作者楊依婷 這樣論述:
帕列托法則為管理學上的熱門議題,指關鍵少數與無用多數的不平衡現象,80/20法則是帕列托法則的延伸,主張小部分的原因、投入或努力,可以產生大部分的結果、產出或酬勞。公共圖書館的流通資料,是讀者實際使用圖書館館藏的紀錄,本研究探討圖書館情境中的80/20法則,以讀者的觀點為基礎,分析公共圖書館近2年的流通資料,研究結果發現24.7%的讀者佔有75.3%的借閱量,符合帕列托法則的現象,有關鍵少數讀者貢獻了大部分的借閱。本研究以資料探勘技術分析關鍵少數讀者的特性、可用多館藏特性,以及兩者的關聯,並應用於目標行銷中,試圖達成公共圖書館的目標行銷。目標行銷三步驟為市場區隔、市場選擇與市場定位,本研究以
帕列托法則的觀點,找出圖書館有少部分的讀者,因佔有大部分的借閱,成為關鍵少數讀者,當作目標行銷中的市場區隔;以分群分析了解關鍵少數讀者的特性,當作目標行銷中的市場選擇;藉由借閱資料的關聯規則分析,得知群集中讀者借閱館藏的關聯,以擬定推銷館藏的策略,當作市場定位。本研究結果有助於公共圖書館個人化服務推廣,以及行銷推展及政策制定,可成為公共圖書館館藏推薦時的參考,幫助公共圖書館在管理、行銷與館藏發展議題上更有效率。
