The Teaching Research On The Cultivation Of "Macro Identification And Micro Analysis" Literacy In The PAD Class Teaching Mode

Focusing on the cultivation of students’ core literacy is a major trend in the field of education.Under the background of the new curriculum reform,the basic education reform based on core literacy has been in full swing.High school chemistry core literacy is an important part of high school students’ core literacy,which shows the important value of high school chemistry to students’ all-round development.Therefore,it is particularly important to implement chemistry core literacy into high school chemistry teaching.The "Opinions on Comprehensively Deepening the Curriculum Reform and Implementing the Fundamental Task of Lide Shuren" points out that it is necessary to promote the learning methods of autonomy,cooperation and inquiry and the teaching methods of inspiration,discussion and participation.And the PAD class teaching mode meets this requirement.Based on this,this study selects the PAD class teaching mode to cultivate "macro identification and micro analysis" literacy.Through reading literature and works,this study understands the research status of the PAD class teaching mode and "macro identification and micro analysis" literacy at home and abroad.Guided by constructivism theory,situational cognition theory and Bruner’s cognitive discovery theory,this study adopts literature research method and questionnaire survey method.On the basis of defining the concepts of sub-classroom teaching mode,bright test assignment and macro identification and micro analysis,the teaching design of the PAD class teaching mode to cultivate "macro identification and micro analysis" literacy is carried out.It aims to construct the corresponding teaching framework and provide more choices for teachers to design teaching.And let students change the traditional receptive learning mode,improve students "macro identification and micro analysis" literacy.First of all,this study conducted a questionnaire survey on high school students to understand the current high school students’ chemistry learning habits,the cognition of "macro identification and micro analysis" literacy and the chemistry classroom teaching methods that students like.It is necessary to adopt the PAD class teaching mode to cultivate "macro identification and micro analysis literacy".Secondly,based on the above survey results,this study proposes a teaching framework for the cultivation of "macro-identification and micro-analysis" literacy in the PAD class teaching mode,including teaching design model,teaching process design and student evaluation design.Finally,according to the teaching framework of cultivating "macro-identification and micro analysis" literacy in the PAD class teaching mode,the teaching cases of "ionization of electrolyte" and "ionic bond" in the compulsory one of high school chemistry in the People’s Education Edition(2019 Edition)and "chemical energy and electric energy" in the compulsory two of high school chemistry in the People’s Education Edition(2019 Edition)are designed to provide some help for chemistry teachers to cultivate students "macro-identification and micro-analysis" literacy.
