「卡片分類法」在歷史教學上的應用
No full text[[abstract]]透過課堂的教學發現，學生自己動手排列歷史事件，除對時代的「時序」與「因果」能較深刻了解外，活動進行的過程就是一個形成性評量，教師從卡片的排列順序可以清楚知道學生的學習問題所在，當下給予回饋讓學生修正及改進他們的思考，更有助於他們的學習。[[fileno]]204_JA04_2006_n17_p2

[[alternative]]The Course Designs of Three U.S. High School History Teachers: A Comment on "A Study of the Teaching Methods of High School History Teacher", The Social Studies (May/June/2008) pp.111~116
No full text[[abstract]]這是一位擁有數學與歷史教育碩士學位的美國高中老師，在2005年所做的研究。她運用事前問卷、現場觀察及課後訪談等質性研究的方式蒐集資料，研究三位美國中學歷史教師的教學方法和其背後的理念。這三位老師可以說並非當今美國中學歷史老師的普遍性樣本，依據作者的說法，大多美國歷史老師仍然以「傳統式」教學為主體，而這三位老師則是被作者認定為在採用新教學理念以促進學生學習效果方面特別有成效的優秀歷史老師。[[fileno]]204_JA04_2008_n19_p13
[[alternative]]A Website Making History Learning Different: Historical Thinking Matters (http://historicalthinkingmatters.org)
No full text[[abstract]]有一個美國網站則有另一種想法，他們的目標是教導學生增進其歷史思維，而不只是補充歷史知識。這個網站不但從站名就開宗明義告訴學生"historical thinking matters"，還在說明中強調，歷史思維不但很重要，它還是必須透過學習才能獲得的能力。[[fileno]]204_JA04_2008_n19_p13
[[alternative]]On Two Totally Different Comments on the Current College Entrance Examination in Taiwan
No full text[[abstract]]近年來的台灣高中歷史教學，可謂是變化甚大的一門學科，無論是課綱、教材、試題，都密集地出現巨大的變革，這種變革，早在教改以前，從民國79年起，高中歷史科大考試題就已嘗試擺脫以往記憶性題目為主的取向，試圖走出台灣歷史科試題思考性取向的特色，在這段近20年的歷程中，除了有許多關心歷史教育的教授們參與，與許多兢兢業業的高中歷史老師投入外，尚有另一股監督的力量，在背後亦步亦趨地仔細考察台灣高中歷史科教學的走向，此監督的力量就是每年大考試題公佈後的評論意見[[fileno]]204_JA04_2009_n20_p4

幸福的成份

食物中包含的與人體荷爾蒙相關的營養素，確實能達到紓解壓力的功效，就像我們在圖書館閱讀小說雜誌所能帶來的放鬆效果一樣。陽光則讓人感到溫暖，就像在圖書館裡面，有著全館同溫的統一空調，不只讓我在寒冬夜裡能夠雙手溫熱，更能夠感受到受到被暖氣包圍的炙熱的心靈。人每日攝取的營養素更像是館內的報章圖書一樣，供給著每日新知識與其他日積月累的資訊。
圖中的人躺在大樹底下休憩，夢到中午剛吃完的香蕉，產生的那一股幸福的感覺充斥、縈繞全身上下久久不散；旁邊的麥穗在陽光與威風的輕拂之下飄動著輕盈的身軀，傳達著春天的信息。融合在這一幅和諧畫面之中的，除了天邊的悠閒浮動的白雲外，還有一冊冊書本堆疊而成的圖書館。她散發出的光線並非逼視的，取而代之的是和煦慈祥的光輝，但卻又是那麼令人難以忘懷的美麗。
圖書館是一個好地方。每天都去圖書館的我，或查詢所需資料，或翻閱報章雜誌放鬆心情。更多的是，什麽也不做，獨享單純芬芳帶點輕盈的書香，品茗靜思人與人之間的心靈交流，體驗圖中主人翁的那一份無拘無束，快樂寫意的進入夢鄉。[[fileno]]208_SP01_2008_n4
Valley-based field-effect transistors in graphene
Get PDF[[abstract]]An analog of the Datta-Das spin field-effect transistor (FET) is investigated, which is all graphene and based on the valley degree of freedom of electrons/holes. The "valley FET" envisioned consists of a quantum wire of gapped graphene (channel) sandwiched between two armchair graphene nanoribbons (source and drain), with the following correspondence to the spin FET: valley (K and K') spin (up and down), armchair graphene nanoribbons ferromagnetic leads, graphene quantum wire semiconductor quantum wire, valley-orbit interaction Rashba spin-orbit interaction. The device works as follows. The source (drain) injects (detects) carriers in a specific valley polarization. A side gate electric field is applied to the channel and modulates the valley polarization of carriers due to the valley-orbit interaction, thus controlling the amount of current collected at the drain. The valley FET is characterized by (i) smooth interfaces between leads and the channel, (ii) strong valley-orbit interaction for electrical control of drain current, and (iii) vanishing interband valley-flip scattering. By its analogy to the spin FET, the valley FET provides a potential framework to develop low-power FETs for graphene-based nanoelectronics.[[fileno]]2030120010047[[department]]電機工程學
DC-Bus Voltage Control with a Three-Phase Bi-directional Inverter for DC Distribution Systems
No full text[[abstract]]This paper presents dc-bus voltage control with a three-phase bidirectional inverter for dc distribution systems. The bidirectional inverter can fulfill both grid connection and rectification modes with power factor correction. The proposed control includes two approaches, one line-cycle regulation approach (OLCRA) and one-sixth line-cycle regulation approach (OSLCRA), which take into account dc-bus capacitance and control dc-bus voltage to track a linear relationship between the dc-bus voltage and inverter inductor current. Since both of the approaches require the parameter of dc-bus capacitance, this paper first presents determination of dc-bus capacitor size and an online capacitance estimation method. With the OLCRA, the inverter tunes the dc-bus voltage every line cycle, which can reduce the frequency of operation-mode change and current distortion. The OSLCRA adjusts current command every one-sixth line cycle to adapt to abrupt dc-bus voltage variation. The two approaches together can prevent dc-bus voltage from wide variation and improve the availability of the dc distribution systems without increasing dc-bus capacitance. Experimental results measured from a three-phase bidirectional inverter have verified the feasibility of the discussed control approaches.[[fileno]]2030197010001[[department]]電機工程學
