實驗、實訓與上機課可以采用自主學習方式。自主學習方式是一種學習者在總體教學目標的宏觀調控下,在教師的指導下,根據自身條件和需要自由地選擇學習目標,學習內容和方法,并通過自我調控的學習活動完成具體學習目標的學習方式。自主學習離不開教師的適時指導與評價,學生只有在教師的適時幫助下,才能不斷地完成一個又一個實驗與實訓項目,獲得越來越大的成就感,增加自己自主學習的動力,從而保證自主學習方式的良性發展。教師還必須結合理論課程的進程,結合實驗實訓設備編寫由淺入深、逐步遞進、面向不同層次學生的實驗實訓指導書,為學生的自主學習提供有力的理論支撐。
3、綜合實訓是PLC課程zui重要的一個環節。要安排充足的時間進行,還要提高實訓的效率,綜合考慮學生個體的差異。在實訓中,遵循能者多勞,共同提高的原則,把學生按個體差異分組,各組根據自己的能力情況選擇不同控制要求的實訓內容,根據控制要求,進行編程、調試,故障診斷與排除。這種方法較靈活的解決了學生能力差異存在的相互制約問題,同時也培養了學生的分工及團隊合作的能力。

三、成績評價機制。應該明確成績評價不是教學行為的zui終目的,成績評價應作為激勵學生學習的一種方法,成績評價應做到及時、公正,具有可操作性。1、理論成績評定包括筆試成績、平時成績和實驗成績,筆試成績通過開卷或閉卷方式,考核了學生對PLC基本知識的掌握程度;平時成績通過平時獨立完成作業的質量、上課出勤、課堂上解決問題的能力及創新方法等來評定;2、實驗實訓成績評價應能體現出競爭機制,根據不同的任務要求分兩種情況:*,保證完成質量的前提下,根據完成速度評定分數;第二,保證統一時間的前提下,根據完成質量評定分數。教師根據完成質量或速度只對每個團隊進行分數評定,團隊每個成員的分數則依據教師給定分數通過本團隊民主評議得分,這樣促進團隊內每個成員的積極性與主動性,同時培養學生的團隊意識。
四、校內學習與校外鍛煉。學生在學校所學的PLC知識與技能對比實際工作崗位中的PLC控制系統,仍具有一定的差異或差距,學生就業后在工作崗位中一定會遇到一些難于解決的難題,這就需要學校、教師仍然要加強對學生畢業工作過程的指導,把這些問題的解決方法做成典型案例對在校學生講解,對在校生來說也是一種良好經驗的積累。學生就業后,在工作崗位上應不斷地與學校教師溝通,不斷地向有經驗的師傅請教,才能熟練掌握PLC控制系統的設計與應用。
總之,作為學校只有做到以上若干方面協同優化,才能真正培養出高素質應用型PLC人才。
