Research On "TRTM" Based On Hand-held Technology

Hand-held technology is a new science experimental mean,which was introduced into middle school chemistry teaching at the end of the 20th century.Real-time,accuracy,comprehensiveness are its characteristics,hand-held technology has accepted and used by more and more teachers.The students' personality and cooperative consciousness are developed,it bring new changes to the current middle school chemistry experiment teaching.Hand-held technology with"TRTM" and POE teaching strategy are combined,case study of existing cases."Chemical energy and heat energy"anda"acid-base neutralization reaction"are designed to have two classes.Research on"TRTM"based on hand-held technology,combination of theoretical research and practical interview is studied.Six parts constitute this article.The issue,the content,the methods and the significance of research in the first part.The second part mainly introduces the related concepts in the research,including the concept of hand-held technology,the advantages and disadvantages,the basic overview of the "TRTM" and the POE teaching strategy.Some classical teaching cases are selected and studied in the third part."Chemical energy and heat energy"and"acid-base neutralization reaction"are designed in the fourth part.The sixth part is the result of comprehensive research and practical interview on the existing cases.It is considered that the "TRTM"conforms to the modern educational idea and is feasible in the actual teaching,and the implementation suggestion is given.
