Standard guide for designing and conducting visual experiments 設計和操縱可視實驗標準指南
The visual experiments also involved manipulated faces and facial features . in this case , observers would focus on a black dot . to the dot ' s right were lips that were fat or thin , or smiling or frowning 同樣地,在第二組試驗中,參與者也被要求把注意力集中在一個黑點上,黑點右邊是或薄或厚或微笑或生氣的嘴唇,而黑點左邊是一整張面孔。
According to the modern education theory , we should adopt the following tactics in teaching the concept of chemistry : 1 . use the vivid visual image to let the students gain the knowledge of the concept ; 2 . create the atmosphere and let the students take part in the formation of the concept of chemistry ; 3 . revise the old knowledge while learning the new one to realize the assimilation of concept ; 4 . proceed step by step , lead the students deepen and develop the concept ; 5 . give prominence to the understanding of the key words of the concept , get deeper understanding ; 6 . pay attention to the relation between the concepts ; 7 . optimize the study strategy and enhance the cognition standard , i . e . in the teaching of the concept of chemistry , we must pay great attention to the usage of various kinds of teaching method , including visual experiment , visual language and cai courseware , in order to help the students to understand the concept ; use the question to stimulate students " thoughts , give free rein to students " corpus , and let the students take part in the teaching process actively ; guide the students to remember new concepts and the help of their old knowledge ; pay attention to the levels of the concept , deepen and develop the concept continuously , use various ways to strengthen the meaning of the key words , help the students to master the concepts connotation , and give a clear extension , guide the students to found the concept system 也就是說,在化學概念的教學中,要注意充分運用各種直觀教學手段,包括實驗直觀、語言直觀和cai課件直觀,幫助學生理解概念;注意運用問題啟動學生思維,發(fā)揮學生的主體性,使學生積極參與教學過程;要指導學生利用原有認知結構中適當?shù)母拍顖D式來學習新概念;注意概念教學的層次性,不斷深化和發(fā)展概念;注意通過各種方式強化概念中關鍵字、詞的意義,幫助學生準確把握概念的內涵,清晰界定概念的外延;注意引導學生在應用中建立概念系統(tǒng),形成合理的概念結構。同時在概念教學中還要注重學習方法的傳授和學習策略的形成,進行適當?shù)脑J知訓練,優(yōu)化學生的學習策略,提高其元認知水平。根據(jù)化學概念的教學策略,化學概念的基本教學程序為:創(chuàng)設問題情境,引入概念;組織問題解決,建立概念;引導知識整理,概念系統(tǒng)化;指導練習應用,概念具體化。
Abstract : visual experiment was carried out for the enhanced boiling heat transfer in evaporation region of thermosyphon . analysis had been carried out to test the results . a physical model describing an enhanced boiling heat transfer in evaporation region were proposed based on the analysis results , thus providing theory references for development of heat pipe technology 文摘:通過對熱虹吸管蒸發(fā)段強化傳熱進行可視化實驗研究并對其結果進行分析討論,在此基礎上建立了熱虹吸管蒸發(fā)段強化傳熱物理模型,為熱管技術的發(fā)展提供理論依據(jù)
