這主要存在一些難點(diǎn)，比如：首先是當(dāng)前我國(guó)教育整個(gè)信息化的程度還很低，教育者信息化素質(zhì)還較低，提不出多少實(shí)際的數(shù)據(jù)挖掘應(yīng)用需求；數(shù)據(jù)挖掘作為 36 一種工具，通過(guò)歷史數(shù)據(jù)預(yù)測(cè)學(xué)習(xí)者的未來(lái)行為，但實(shí)際上連學(xué)習(xí)者自己有時(shí)都不清楚下一步要做什么；此外 學(xué)習(xí)者的特征、學(xué)習(xí)過(guò)程及學(xué)習(xí)結(jié)果有時(shí)是難以用數(shù)量方式進(jìn)行描述，開發(fā)的難度較大；數(shù)據(jù)挖掘在教育信息化中的應(yīng)用涉及到對(duì)學(xué)習(xí)者特征的提取，這就牽扯到社會(huì)環(huán)境、文化背景、價(jià)值理念等多方面，國(guó)情不同、地域不同，知識(shí)發(fā)現(xiàn)的算法就不同 ， 因此，國(guó)外的經(jīng)驗(yàn)只能借鑒，不能簡(jiǎn)單照搬。 目前“一體化智能教學(xué)網(wǎng)絡(luò)平臺(tái)”的子項(xiàng)目“ 基于 DW的成績(jī)?cè)u(píng)定系統(tǒng) ”的初始 版本已交付給學(xué)校進(jìn)行試用，本項(xiàng)目的開發(fā)人員 正積極準(zhǔn)備進(jìn)行下一次的迭代開發(fā)。筆者進(jìn)行了多年的思考與研究， 提出了關(guān)于教育評(píng)價(jià)管理的“三向 ” 智能評(píng)估策略 的需求 ， 并充分利用最新的信息技術(shù)解決評(píng)價(jià)改革中的問(wèn)題，在 架構(gòu)設(shè)計(jì) 思想 SOA 和 其它 技術(shù)的指導(dǎo)下，設(shè)計(jì)出“一體化智能教學(xué)網(wǎng)絡(luò)平臺(tái)”架構(gòu) 藍(lán)圖 ，為新一代的智能教學(xué) 網(wǎng)絡(luò)環(huán)境的設(shè)計(jì)提供了參照。因此教育開始進(jìn)行全面改革，實(shí)現(xiàn)教育現(xiàn)代化、信息化。 雖然這個(gè)功能很簡(jiǎn)單，但作為一個(gè)項(xiàng)目的原型，為其它廣泛的數(shù)據(jù)挖掘應(yīng)用提供了技術(shù)基礎(chǔ)。實(shí)際該生 20xx 年的高考升學(xué)成績(jī)?yōu)?606 分，已考入西安電子科技大學(xué)的電子信息工程專業(yè)。我們對(duì) 200 名 06 級(jí)理科學(xué)生進(jìn)行了預(yù)測(cè)測(cè)試，結(jié)果理想。 目前我們開發(fā)的軟件原型，整個(gè)工作都可以說(shuō)是為了進(jìn)行測(cè)試，這里限于篇幅， 將不再敘述，下面的應(yīng)用就是一個(gè)測(cè)試。 6） 對(duì)代碼進(jìn)行重構(gòu)，并保證測(cè)試通過(guò)。 4） 編寫 對(duì)應(yīng)的功能代碼。 2） 快速完成針對(duì)此功能的測(cè)試用例編寫。測(cè)試驅(qū)動(dòng)開發(fā)就是通過(guò)編寫 測(cè)試用例 ，先考慮代碼的使用需求（包括功能、過(guò)程、接口等），而且這個(gè)描述是無(wú)二義的，可執(zhí)行驗(yàn)證的。 33 第六章 測(cè)試工作流 測(cè)試工作流對(duì)于項(xiàng)目開發(fā)是至關(guān)重要的， 因此 ，做為質(zhì)量保證的重要手段，極限編程的重要特點(diǎn) 就是 測(cè)試驅(qū)動(dòng)開發(fā)（ TestDriven Development）。 } 用 Web Services 把服務(wù)包裝好，發(fā)布到網(wǎng)上。 theProbability =
