實(shí)驗(yàn)、實(shí)訓(xùn)與上機(jī)課可以采用自主學(xué)習(xí)方式。自主學(xué)習(xí)方式是一種學(xué)習(xí)者在總體教學(xué)目標(biāo)的宏觀調(diào)控下，在教師的指導(dǎo)下，根據(jù)自身?xiàng)l件和需要自由地選擇學(xué)習(xí)目標(biāo)，學(xué)習(xí)內(nèi)容和方法，并通過自我調(diào)控的學(xué)習(xí)活動(dòng)完成具體學(xué)習(xí)目標(biāo)的學(xué)習(xí)方式。自主學(xué)習(xí)離不開教師的適時(shí)指導(dǎo)與評(píng)價(jià)，學(xué)生只有在教師的適時(shí)幫助下，才能不斷地完成一個(gè)又一個(gè)實(shí)驗(yàn)與實(shí)訓(xùn)項(xiàng)目，獲得越來越大的成就感，增加自己自主學(xué)習(xí)的動(dòng)力，從而保證自主學(xué)習(xí)方式的良性發(fā)展。教師還必須結(jié)合理論課程的進(jìn)程，結(jié)合實(shí)驗(yàn)實(shí)訓(xùn)設(shè)備編寫由淺入深、逐步遞進(jìn)、面向不同層次學(xué)生的實(shí)驗(yàn)實(shí)訓(xùn)指導(dǎo)書，為學(xué)生的自主學(xué)習(xí)提供有力的理論支撐。

     3、綜合實(shí)訓(xùn)是PLC課程zui重要的一個(gè)環(huán)節(jié)。要安排充足的時(shí)間進(jìn)行，還要提高實(shí)訓(xùn)的效率，綜合考慮學(xué)生個(gè)體的差異。在實(shí)訓(xùn)中，遵循能者多勞，共同提高的原則，把學(xué)生按個(gè)體差異分組，各組根據(jù)自己的能力情況選擇不同控制要求的實(shí)訓(xùn)內(nèi)容，根據(jù)控制要求，進(jìn)行編程、調(diào)試，故障診斷與排除。這種方法較靈活的解決了學(xué)生能力差異存在的相互制約問題，同時(shí)也培養(yǎng)了學(xué)生的分工及團(tuán)隊(duì)合作的能力。

 三、成績(jī)?cè)u(píng)價(jià)機(jī)制。應(yīng)該明確成績(jī)?cè)u(píng)價(jià)不是教學(xué)行為的zui終目的，成績(jī)?cè)u(píng)價(jià)應(yīng)作為激勵(lì)學(xué)生學(xué)習(xí)的一種方法，成績(jī)?cè)u(píng)價(jià)應(yīng)做到及時(shí)、公正，具有可操作性。1、理論成績(jī)?cè)u(píng)定包括筆試成績(jī)、平時(shí)成績(jī)和實(shí)驗(yàn)成績(jī)，筆試成績(jī)通過開卷或閉卷方式，考核了學(xué)生對(duì)PLC基本知識(shí)的掌握程度；平時(shí)成績(jī)通過平時(shí)獨(dú)立完成作業(yè)的質(zhì)量、上課出勤、課堂上解決問題的能力及創(chuàng)新方法等來評(píng)定；2、實(shí)驗(yàn)實(shí)訓(xùn)成績(jī)?cè)u(píng)價(jià)應(yīng)能體現(xiàn)出競(jìng)爭(zhēng)機(jī)制，根據(jù)不同的任務(wù)要求分兩種情況：*，保證完成質(zhì)量的前提下，根據(jù)完成速度評(píng)定分?jǐn)?shù)；第二，保證統(tǒng)一時(shí)間的前提下，根據(jù)完成質(zhì)量評(píng)定分?jǐn)?shù)。教師根據(jù)完成質(zhì)量或速度只對(duì)每個(gè)團(tuán)隊(duì)進(jìn)行分?jǐn)?shù)評(píng)定，團(tuán)隊(duì)每個(gè)成員的分?jǐn)?shù)則依據(jù)教師給定分?jǐn)?shù)通過本團(tuán)隊(duì)民主評(píng)議得分，這樣促進(jìn)團(tuán)隊(duì)內(nèi)每個(gè)成員的積極性與主動(dòng)性，同時(shí)培養(yǎng)學(xué)生的團(tuán)隊(duì)意識(shí)。 

    四、校內(nèi)學(xué)習(xí)與校外鍛煉。學(xué)生在學(xué)校所學(xué)的PLC知識(shí)與技能對(duì)比實(shí)際工作崗位中的PLC控制系統(tǒng)，仍具有一定的差異或差距，學(xué)生就業(yè)后在工作崗位中一定會(huì)遇到一些難于解決的難題，這就需要學(xué)校、教師仍然要加強(qiáng)對(duì)學(xué)生畢業(yè)工作過程的指導(dǎo)，把這些問題的解決方法做成典型案例對(duì)在校學(xué)生講解，對(duì)在校生來說也是一種良好經(jīng)驗(yàn)的積累。學(xué)生就業(yè)后，在工作崗位上應(yīng)不斷地與學(xué)校教師溝通，不斷地向有經(jīng)驗(yàn)的師傅請(qǐng)教，才能熟練掌握PLC控制系統(tǒng)的設(shè)計(jì)與應(yīng)用。

     總之，作為學(xué)校只有做到以上若干方面協(xié)同優(yōu)化，才能真正培養(yǎng)出高素質(zhì)應(yīng)用型PLC人才。
