【文章內(nèi)容簡介】 文、音像并茂，因而在激發(fā)學生興趣，提高學生的主動性、積極性方面受到較大的限制。 可見，在多 媒體教學系統(tǒng)和智能輔助教學系統(tǒng)之間存在性能互補關(guān)系，二者結(jié)合起來才 可以揚長避短，從而研制出高性能的新一代智能輔助教學系統(tǒng)。 四 .多媒體技術(shù)與建構(gòu)主義學習理論的結(jié)合 如前所述 建構(gòu)主義學習理論是認知學習理論的一個重要分支，但是 ， 在很長一段時期內(nèi)并未產(chǎn)生明顯的影響。直至近年來，隨著多媒體技術(shù)的日益普及，才逐漸引起人們的廣泛的注意，按照建構(gòu)主義學習環(huán)境進行教改試驗研究的學校也日漸增多。建構(gòu)主義學習環(huán)境包含四大屬性或四大要素即“情景”、“協(xié) 商”、“會話”和“意義建構(gòu)”。 多媒體技術(shù)的特性與功能最有利于四大屬性的充分體現(xiàn) ， “情景”──建構(gòu)主義學習理論強調(diào)創(chuàng)設(shè)真實情景，把創(chuàng)設(shè)情景看作是“意義建構(gòu)”的必要前提，并作為教學設(shè)計的最重要內(nèi)容之一。而多媒體技術(shù)正好是創(chuàng)設(shè)真實情景的最有效工具，如果再與仿真技術(shù)相結(jié)合，則更能產(chǎn)生身臨其境的逼真效果。 “協(xié)商”與“會話”──協(xié)商與會話過程主要通過語言作媒介，這就要求計算機輔助教學系統(tǒng)必須要有語音功能，即要用多媒體計算機才能支持。 “意義建構(gòu)” 。 意義建構(gòu)是學習的目的，它要靠學生自覺、主動去完成。教師和外界環(huán)境的作用都是為了幫助和促進學生的意義建構(gòu)。多媒體技術(shù)由于能提供界面友好、形象直觀的 交互式學習環(huán)境，能提供圖文聲并茂的多重感官綜合刺激，還能按超文本方式組織與管理各種教學信息和學科知識，因而對學生認知結(jié)構(gòu)的形成與發(fā)展，即對學生關(guān)于當前所學知識的意義建構(gòu)是非常有利的，也是其它媒體或其他教學環(huán)境無法比擬的。 14 / 60 正因如此 ，近年來建構(gòu)主義學習環(huán)境更趨完善，建構(gòu)主義學習理論也就日漸風行。當然，這不等于說建構(gòu)主義學習理論是萬應(yīng)靈丹，能解決學習領(lǐng)域的一切問題 (例如，情感領(lǐng)域和動作技能領(lǐng)域的教育目標就不一定能通過建構(gòu)主義學習環(huán)境來達到 )，但是就認知領(lǐng)域的教育目標而言，借助多媒體技術(shù) (若有條件還可結(jié)合網(wǎng)絡(luò)通信 技術(shù) )實現(xiàn)的建構(gòu)主義學習環(huán)境，確實非常有利于學生認知結(jié)構(gòu)的形成與發(fā)展則已得到愈來愈多試驗的證實。這是值得我們國內(nèi)教育界認真思索與借鑒的。 結(jié) 束 語 多媒體教學已被實踐證明是一種行之有效的 輔助 教學手段。 合理地 利用多媒體教學，一方面可以創(chuàng)造生動活潑的 教學 情景，激發(fā)學生的學習興趣，讓學生在愉悅的環(huán)境中獲取 基礎(chǔ) 知識， 優(yōu)化課堂教學，提高 學習 效率，提高教學質(zhì)量 ；另一方面， 實際 應(yīng)用中也 確實 存在一些問題，但這些不應(yīng)該阻礙多媒體教學應(yīng)用的發(fā)展， 我們畢竟應(yīng)順應(yīng)時代發(fā)展的潮流， 更新教學理念。所以， 如何有效地運用多媒體教學 手段達到提高教學效果和教學 效率的目的， 并不斷改進和完善， 是 教育界人士 應(yīng)該 長期 正確面對 和 深入研究 的課題 。 【 參考文獻 】 [1]劉逸文 .冷眼相看多媒體教學 [J].教學儀器與實驗 .第 17 卷 2020 年第 1 期 [2]丁俊 .多媒體技術(shù)在計算機教學中的應(yīng)用 [J].福建電腦 .2020 年第 5 期 [3]馬占山 .多媒體教學的優(yōu)勢及其存在的問題和對策 [B].青海師專學報 (教育科學 ).2020 年第 6 期 [4]賴文繼 .關(guān)于多媒體教學新模式的探究 [C].桂林電子工業(yè)學院學報 .第 25 卷第 2 期 2020 年 4 月 [5]周毓萍 。余益峰 . 多 媒體和網(wǎng)絡(luò)現(xiàn)代教育模式對培養(yǎng)大學生信息素養(yǎng)的影響 2020(01) [6]徐世貴 . 新課程與教師專業(yè)能力的提升 2020 [7]趙莉 .論多媒體技術(shù)在教學中的作用 2020(04) [8]陳艷容 .多媒體教學的 優(yōu) 與 優(yōu) 2020(02) 15 / 60 [9]陳偉華 . 基于多媒體輔助的引探發(fā)現(xiàn)教學模式 [期刊論文 ] 教育導(dǎo)刊2020(10) doi:[10]黃曉洲 .多媒體教學的研究與實踐 2020(32) [11]方其桂 .CAI 課件制作教程 2020 [12]瞿彩萍 .多媒體輔助教學的優(yōu)勢和存在的問題 2020(10) 16 / 60 （英文版 ） Two regulations promulgated for implementation is in the party in power for a long time and the rule of law conditions, the implementation of prehensive strictly strategic plan, implementation in accordance with the rules and discipline to manage the party, strengthen innerparty supervision of major initiatives. The two regulations supporting each other, the code adhere to a positive advocate, focusing on morality is of Party members and Party leading cadres can see, enough to get a high standard。 rule around the party discipline, disciplinary ruler requirements, listed as negative list, focusing on vertical gauge, draw the party anizations and Party members do not touch the bottom line . Here, the main from four square face two party rules of interpretation: the first part introduces two party Revised regulations the necessity and the revision process。 the second part is the interpretation of the two fundamental principles of the revision of laws and regulations in the party。 the third part introduces two party regulations modified the main changes and needs to grasp several key problems。 the fourth part on how to grasp the implementation of the two regulations of the party. code and Regulations revised the necessity and revised 17 / 60 history of the CPC Central Committee the amendment to the Chinese Communist Party members and leading cadres honest politics several guidelines and Chinese Communist Party discipline and Punishment Regulations column 1 by 2020 to strengthen party laws and regulations focus. Two party regulations revision work lasted a Years, pooling the wisdom of the whole party, ideological consensus, draw historical experience, respect for the wisdom of our predecessors, which reflects the unity of inheritance and innovation。 follow the correct direction, grasp the limited goals, adhere to the party39。s leadership, to solve the masses of the people reflect a focus on the problem. The new revision of the code and rule , reflects the party39。s 18 and the eighth session of the third, the spirit of the fourth plenary session, reflecting the experience of studying and implementing the General Secretary Xi Jinping series of important speech, reflects the party39。s eighteen years prehensive strictly practice. (a) revised two regulations of the party need of the ICAC guidelines in in 1997 Leaders as members of the Communist Party of China clean politics certain criteria (Trial) based on revised, the promulgation and implementation of January 2020, to strengthen the construction of the contingent of leading cadres play an 18 / 60 important role. But with the party to manage the party strictly administering the deepening, has not been able to fully meet the actual needs. Content is too plicated, eight prohibition, 52 are not allowed to hard to remember, and also difficult to put into practice。 the second is concisely positive advocated by the lack of prohibited provisions excessive, no autonomy requirements。 the third is banned terms and discipline law, both with the party discipline, disciplinary regulations repeat and Criminal law and other laws and regulations repeat。 the fourth is to clean the theme is not prominent, not for the existing problems, and is narrow, only needle of countylevel leading cadres above. rule is in 1997 Chinese Communist Party disciplinary cases (Trial) based on revision, in December 2020 the promulgation and implementation, to strengthen the construction of the party play very important role. Along with the development of the situation, which many provisions have been unable to fully meet the prehensive strictly administering the practice needs. One is Ji law, more than half of the provisions and criminal law and other countries laws and regulations Repetition。 two is the political discipline regulations is not prominent, not specific, for violation of the party constitution, damage the 19 / 60 authority of Party Con
