基于JSP的遠(yuǎn)程教學(xué)系統(tǒng)的設(shè)計(jì)與實(shí)現(xiàn)

摘要
Internet互聯(lián)網(wǎng)已經(jīng)深入許許多多普通人每天的生活，它的觸角也漸漸滲透到社會(huì)的各個(gè)角落。在這場(chǎng)信息改革浪潮中，高校作為新技術(shù)的前沿陣地，如果成功地運(yùn)用Internet技術(shù)，它將會(huì)成為高校教學(xué)工作改革的催化劑。[1]
在傳統(tǒng)的教學(xué)方式中，師生每天在教室里面對(duì)面地上課、提問(wèn)和答疑；課后學(xué)生做完作業(yè)，等著教師的批改結(jié)果；考試場(chǎng)上，教師一刻不停地監(jiān)考，學(xué)生緊張地答卷等。這種體制下出現(xiàn)的各種不良結(jié)果，常見(jiàn)的有學(xué)生厭學(xué)情緒嚴(yán)重、抄襲別人作業(yè)、考試作弊，更有甚者直至荒廢學(xué)業(yè)。[2]如何克服傳統(tǒng)教學(xué)弊端，提高教師學(xué)生工作學(xué)習(xí)的效率，降低教師的工作壓力，減輕學(xué)生的學(xué)業(yè)負(fù)擔(dān)，提高學(xué)生的學(xué)習(xí)積極性，同時(shí)熟悉計(jì)算機(jī)操作，發(fā)揮計(jì)算機(jī)和Internet 網(wǎng)絡(luò)在教學(xué)工作中的作用，是本論文主題探索研究的方向。現(xiàn)在一些運(yùn)行的教學(xué)系統(tǒng)，要么是采用基于局域網(wǎng)的C/S結(jié)構(gòu)的平臺(tái)，要么是采用ASP技術(shù)開(kāi)發(fā)的網(wǎng)絡(luò)教學(xué)系統(tǒng)。本論文選擇JSP+SQLServer搭建網(wǎng)絡(luò)教學(xué)系統(tǒng)平臺(tái)，它們是當(dāng)今世界最前沿最流行的兩種網(wǎng)絡(luò)開(kāi)發(fā)技術(shù)的黃金搭配組合。JSP技術(shù)日趨穩(wěn)定成熟，它擁有卓越的系統(tǒng)可移植性，同時(shí)它與流行的XML等技術(shù)也能良好整合，加上SQLServer2000數(shù)據(jù)庫(kù)強(qiáng)大的后臺(tái)數(shù)據(jù)支持，奠定了JSP技術(shù)在網(wǎng)絡(luò)應(yīng)用系統(tǒng)開(kāi)發(fā)中的關(guān)鍵地位。[3]
這次的畢業(yè)設(shè)計(jì)開(kāi)發(fā)了計(jì)算機(jī)科學(xué)與工程學(xué)院遠(yuǎn)程教學(xué)系統(tǒng)V1.0。這種平臺(tái)不僅滿足了傳統(tǒng)教學(xué)的基本要求，并且充分運(yùn)用了計(jì)算機(jī)和網(wǎng)絡(luò)技術(shù)，有效彌補(bǔ)了現(xiàn)行教學(xué)方式的不足，學(xué)生選課后，實(shí)行教師上傳學(xué)生下載的學(xué)習(xí)過(guò)程同時(shí)還可以相互留言實(shí)行互動(dòng)環(huán)節(jié)。隨著教學(xué)系統(tǒng)的應(yīng)用、更新和完善，平臺(tái)將給學(xué)校教學(xué)工作注入新的活力，并且有效地促進(jìn)學(xué)校教學(xué)改革工作的蓬勃開(kāi)展。[7]

Design and realization of long range teaching system
Abstract
Internet already thorough allow much more life of the common run of people everyday, it of the antenna also gradually seeps through each social corner. In this information reform wave tide, high school conduct and actions be lately technical of ex- follow battlefield, if successfully make use of an Internet technique, it will become high school teaching a work the catalyst of reform.
In the traditional teaching method, the teachers and the students face to face have a class, lift to ask and answer Yi in the classroom everyday; The student finishes do homework after the lesson and wait for the result of correct of teacher; On the examination field, the teacher never stop for a moment supervises and the student nervously answers an etc..Various bad result that this kind of bottom of the system appear, familiarly have a student to be disgusted with to learn motion severity and plagiarize other people's homework, cheat in an examination, have more very until neglected studies. How overcome traditional teaching irregularity, raise a teacher student to work the efficiency for study, lower the teacher's work pressure, lighten the student's studies burden, the exaltation aggressive of study of student, acquaint with calculator operation, exertive calculator and Internet network to work in the teaching a medium function in the meantime, is this thesis topic quest research of direction.Now some teaching systems of movements, the Yao is an adoption the terrace of the structure is according to the C/S of the bureau area net, Yao is adopt ASP technique development of network teaching system. This thesis chooses JSP+SQLServer build the system terrace of the network teaching and they are a world to follow two kinds of most popular networks to develop technical gold to match a combination ago most nowadays. The JSP technique is gradually stable mature, it owns outstanding system and can transplant sex, in the meantime it with popular of XML etc. technique also ability good integration, plus SQLServer2000 databases a strong backstage data support, established a JSP technique in the network the application the system the development of key position.
The graduation design this time develop calculator science and the system V1.0 of the long range teaching of the engineering college. This kind of terrace not only satisfied the basic request of traditional
teaching, but also made the most of calculator and network technique, effectively made up the shortage of current teaching method, student after select elective courses, practice a teacher to up spread the student download of the learning process can leave a message to practice interaction link still mutually in the meantime. Along with the application, renewal of teaching system with perfect, the terrace will work to infuse into new vitality for school teaching, and availably help the school reform in education to work of booming open an exhibition.
Keywords: Long range teaching; Up spread a download; Select elective courses; Leave a message.
