Research Of Teaching Practice Based On Modern Chemistry Experimental Technology And Methods

Modern chemical experiment technology and method teaching is an important method which can merge modern science and technology into chemical experiment teaching. So it can fully reflect the student-centered, teacher-led educational thinking.Rational utilization of this teaching model can not only optimize the teaching process and improve teaching efficiency, but also help cultivate students' creative ability,scientific thinking and exploration ability.Through literature research, this paper summed up the current situation of chemistry experiment teaching mode in middle school, and analyzed the characteristics and advantages of modern chemical experiment technology and method teaching. Then the idea of integrating modern scientific technology with chemistry experiment teaching was proposed in order to optimize teaching process.And its concept, characteristic and operability were also summarized and analyzed.The thesis is composed of three parts:By consulting lots of references, Part One analyzed current situation of chemical experiment teaching mode both at home and abroad, and then elaborated the importance and necessity of developing modern technology and method of chemical experiment teaching. What's more, the main research topic, research significance,research methodology and relevant concepts were also briefly introduced in this part.In Part Two, starting with three mainstream teaching materials and subject forefront and combining the characteristics of students, the importance of developing modern chemistry experiment technology and method for students was discussed based on the learning theory of constructivism, humanism and behaviourism.With the help of teaching practice, the third part explored the effects of modern chemical experiment technology and method produced in the actual teaching process.Three successful application cases, such as "acid-base titration curve mapping", "animation of preparation of chlorine" and "determination of the neutralization heat of reaction " were focused on. That demonstrated the feasibility of modern chemical experiment technology and method teaching in further.
