，先考慮代碼的使用需求（包括功能、過程、接口等），而且這個描述是無二義的，可執(zhí)行驗證的。 4） 編寫 對應(yīng)的功能代碼。 目前我們開發(fā)的軟件原型，整個工作都可以說是為了進行測試，這里限于篇幅， 將不再敘述，下面的應(yīng)用就是一個測試。實際該生 20xx 年的高考升學(xué)成績?yōu)?606

正積極準(zhǔn)備進行下一次的迭代開發(fā)。我們對這方面問題的研究，也將大大推進教育信息化的發(fā)展和進步。 using 。 public partial class PublicFunction { //得到考試班級列表 public static ArrayList funClass(int ExamTimeID,int CourseID) { //聲明常量與變量 string

這主要存在一些難點，比如：首先是當(dāng)前我國教育整個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，通過歷史數(shù)據(jù)預(yù)測學(xué)習(xí)者的未來行為，但實際上連學(xué)習(xí)者自己有時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)過程及學(xué)習(xí)結(jié)果有時是難以用數(shù)量方式進行描述，開發(fā)的難度較大；數(shù)據(jù)挖掘在教育信息化中的應(yīng)用涉及到對學(xué)習(xí)者特征的提取，這就牽扯到社會環(huán)境、文化背景、價值理念等多方面，國情不同、地域不同，知識發(fā)現(xiàn)的算法就不同 ， 因此，國外的經(jīng)驗只能借鑒，不能簡單照搬。筆者進行了多年的思考與研究， 提出了關(guān)于教育評價管理的“三向 ” 智能評估策略 的需求 ， 并充分利用最新的信息技術(shù)解決評價改革中的問題，在 架構(gòu)設(shè)計 思想 SOA 和 其它 技術(shù)的指導(dǎo)下，設(shè)計出“一體化智能教學(xué)網(wǎng)絡(luò)平臺”架構(gòu) 藍圖 ，為新一代的智能教學(xué) 網(wǎng)絡(luò)環(huán)境的設(shè)計提供了參照。 雖然這個功能很簡單，但作為一個項目的原型，為其它廣泛的數(shù)據(jù)挖掘應(yīng)用提供了技術(shù)基礎(chǔ)。我們對 200 名 06 級理科學(xué)生進行了預(yù)測測試，結(jié)果理想。 6） 對代碼進行重構(gòu)，并保證測試通過。 2） 快速完成針對此功能的測試用例編寫。 33 第六章 測
