中文摘要 先備知識為學習者學習中不可或缺之元素,其能夠影響學習者如何去解釋、組織、同化與吸收即將學習的知識或技能,文獻更指出,於學習過程中,學習者若能擁有足夠的先備知識,則能夠提升其學習動機與成效。因此,為了能夠於教學前瞭解學習者之先備知識程度,一般而言,測驗為常被教師使用的方式,然而傳統的測驗往往只會於測驗結果中提供一分數來讓教師與學習者瞭解其測驗結果,如此的方式可能會造成教師與學習者無法清楚的瞭解問題之所在。為此,先前的研究提出一先備知識測量與診斷系統來協助診斷學習者之先備知識能力,進而提升與強化其所需之先備知識,以面對即將來臨的課程;雖然研究結果顯示應用該系統能有效改善學習者的學習成效,但由於該系統僅以測驗中之單一屬性來診斷學習者之先備知識,忽略了此問題其實應為多屬性決策,並且各屬性之重要性往往會隨著教學情境的不同而有所變化,基於此,本研究應用模糊多屬性決策之技術,發展一增強式學習診斷系統來克服上述之問題。為評估此系統,本研究將其應用於實際教學情境中來探討其對於教學成效之影響,實驗結果顯示出本研究所提出之系統能夠改善學習者之學習動機與提升學習成效,最後,本研究針對先備知識之診斷結果來進行分析,其結果顯示所提出之診斷機制能夠準確的診斷出學習者之先備知識的能力。
英文摘要 Students learn new instructions well by building on relevant prior knowledge as such knowledge affects how instructors and students interact with the learning materials. Moreover, studies have found that good prior knowledge can enable students to attain better learning motivation, comprehension, and performance. This suggests it is important to assist students in obtaining the relevant prior knowledge, as this can enable them to engage meaningfully with the learning materials. Generally, tests are often used to help instructors assess students’ prior knowledge. Nevertheless, conventional testing approaches usually assign only a score to each student, and this may mean that students are unable to realize their own individual weaknesses clearly. To address this problem, previous work has developed a prior knowledge testing and diagnosis (PKT&D) system to assist instructors and students in diagnosing and strengthening prior knowledge. Although, the PKT&D system has shown its effectiveness in helping students improve their learning performance, past experiences of applying this model also reveal the limits of applying it. One of the major problems of applying the PKT&D system is that it does not consider the necessity of multiple attributes when identifying the learning problems of individual students. Moreover, the importance ratios of these attributes may be varied for different educational contexts or if the instructors have different opinions about them. Therefore, this study applied the Efficient Fuzzy Weighted Average (EFWA) technique to develop a Fuzzy Prior Knowledge Test and Diagnosis (FPKT&D) system with a multi-attribute decision making model to deal with these above weaknesses. To demonstrate the usefulness of the FPKT&D system, a quasi-experiment was conducted to evaluate its efficacy with regard to improving teaching and learning performance. Furthermore, an analysis was also performed to investigate how accurately the system can diagnose students’ prior knowledge and thus provide them with appropriate materials to strengthen this.
