【摘要】：智能計算機輔助教學(xué)(即智能CAI)是當(dāng)前教育研究領(lǐng)域內(nèi)的一個熱點。本文將智能CAI的相關(guān)理論和技術(shù)與大學(xué)物理課程結(jié)合,旨在開發(fā)出一個功能相對完善的大學(xué)物理課程智能CAI系統(tǒng),并以此促進(jìn)大學(xué)物理課程教學(xué)改革,提高其教學(xué)的質(zhì)量和效果。 本文系統(tǒng)是以軟件工程思想為指導(dǎo),利用Visual Basic開發(fā)工具結(jié)合Access數(shù)據(jù)庫,并采用基于局域網(wǎng)的客戶端/服務(wù)器(C/S)架構(gòu)體系開發(fā)而成,具體可實現(xiàn)用戶管理、習(xí)題管理、教案管理和試卷管理等多個功能。 本文的理論研究重點在于對系統(tǒng)智能化的設(shè)計。通過對模塊理論、認(rèn)知理論和框架理論等的研究,最終對大學(xué)物理課程智能CAI系統(tǒng)的三個基本模塊分別采用如下設(shè)計思想：①知識庫模塊主要采用習(xí)題和教案兩種表現(xiàn)形式。首先根據(jù)教學(xué)大綱的要求將教學(xué)內(nèi)容細(xì)化為各個最小知識點,然后采用章節(jié)分類的方法將每個知識點加以編碼,最后構(gòu)造知識點之間的影響關(guān)系；對于教案主要依據(jù)所包含的知識點數(shù)量以及知識點的難易程度被設(shè)計為初、中、高3個級別；而對于習(xí)題則需要找出所運用的各個知識點并分別標(biāo)注其編碼,以保證智能教學(xué)策略庫的設(shè)計；②學(xué)生模塊主要是依照布魯姆的目標(biāo)分類理論,將學(xué)習(xí)者的認(rèn)知水平劃分為識記、理解、掌握、綜合、運用和評價6種類型,當(dāng)學(xué)習(xí)結(jié)束后,通過對學(xué)習(xí)結(jié)果的智能分析,找出學(xué)習(xí)者錯誤產(chǎn)生的根源,并準(zhǔn)確定位其認(rèn)知水平；③教師模塊主要根據(jù)學(xué)習(xí)者答題測試的結(jié)果,從答題數(shù)量、平均用時、正確的得分比例以及答題準(zhǔn)確率等方面綜合考慮,由系統(tǒng)自動分析,針對不同的組合形式給出個性化的建議。 本文的主要特色在于：將智能CAI技術(shù)與大學(xué)物理課程結(jié)合,符合實際需求,具有很強的研究意義；在理論研究的基礎(chǔ)上真正地實現(xiàn)了系統(tǒng)的開發(fā),并且系統(tǒng)已經(jīng)投入使用,應(yīng)用前景較好；被開發(fā)的系統(tǒng)包含兩個不同的版本,即：基于PC機的單機版本和基于C/S的網(wǎng)絡(luò)版本,其適應(yīng)范圍較廣；系統(tǒng)的擴展性較強,可以直接被進(jìn)行二次開發(fā),并運用于其它學(xué)科。
[Abstract]:Intelligent computer aided instruction (CAI) is a hot topic in the field of educational research. This paper combines the theory and technology of intelligent CAI with the course of college physics, aiming to develop a relatively perfect intelligent CAI system of college physics course, and to promote the reform of college physics course teaching. Improve its teaching quality and effect. This system is based on the idea of software engineering, using Visual Basic development tools combined with Access database, and using the client / server (C / S) architecture system based on LAN. It can realize user management and exercise management. Teaching plan management and examination paper management and other functions. This paper focuses on the intelligent design of the system. Through the research of module theory, cognitive theory and frame theory, three basic modules of intelligent CAI system of college physics course are designed as follows: 1 knowledge base module mainly adopts exercise and teaching plan. Firstly, according to the requirements of the syllabus, the teaching content is refined into each minimum knowledge point, then each knowledge point is coded by the method of chapter classification, and the influence relationship between the knowledge points is constructed. For the teaching plan mainly based on the number of knowledge points included and the degree of difficulty of the knowledge points are designed for the initial, middle, high three levels; For the exercises, we need to find out the knowledge points and encode them separately to ensure the design of the intelligent teaching strategy library. According to Bloom's goal classification theory, students' cognitive level is divided into six types: memorizing, understanding, mastering, synthesizing, applying and evaluating. Find out the root cause of learners' errors and accurately locate their cognitive level; (3) the teacher module is mainly based on the result of the learner's answer test, which is analyzed automatically by the system, including the number of questions, the average time, the correct score ratio and the accuracy rate of the answer question, and so on. Individualized suggestions are given for different combinations. The main features of this paper are as follows: the combination of intelligent CAI technology and college physics course is in line with the actual needs and has a strong research significance; The development of the system is realized on the basis of theoretical research, and the system has been put into use, and the application prospect is good. The developed system includes two different versions: the single version based on PC machine and the network version based on C / S, which has a wide range of adaptations; the system has strong expansibility and can be directly developed for secondary development and applied to other disciplines.
