Studies On Strategies Of Reflective-Thinking Training For Chemistry Young-Teachers

In the teaching process,the original three-dimensional comprehensive evaluation system,comprehensive performance of the current chemistry core literacy training while the implementation of the new curriculum standards.The new teaching goal emphasizes the change of the teaching subject,puts forward the clear direction and goal for the teacher's teaching,lays the foundation for the students to cultivate a sound personality and leads to a better life in the future.The periodic law is the basis of inorganic chemistry and the sublimation of the knowledge of elemental compounds,the revelation of the periodic law of elements systematically relates the properties of elements,using the close relationship among the positions in the periodic table,the atomic structure and the properties of elements can guide the study of chemistry,In the study of the periodic law of the elements,students need to master the bridge between constructing atomic microstructure and macroscopic properties of elements,to establish the knowledge model of position-structure-property-application(referred to as "position,structure,sex,use "),and to use model thought to solve the change of element properties.Therefore,teaching strategies based on chemistry core literacy are of great significance under the guidance of the new curriculum standards.Based on the core literacy,the main research content of this paper is the chemistry teaching strategy research,which is implemented —— " the element cycle law ".The article can be divided into the following four parts:The first part,based on the chemistry curriculum standards,discusses the research background of the cultivation of chemistry core literacy,analyzes the characteristics of the periodic law knowledge,the establishment of the periodic law knowledge system and the relationship between chemistry core literacy.The related concepts of this study are defined through the research and analysis of literature theory.According to the analysis of students' cognitive development level and learning situation,we can choose the basic teaching theory.It is embodied in the following aspects: based on the core accomplishment of chemistry,following the theory of cognitive development,and implementing the application of humanism theory,STSE theory and constructivism theory in the teaching of periodic law oelementary.Through the review of the current situation of chemical core literacy research at home and abroad,we can understand the importance of cultivating students' chemical core literacy practice in front-line teaching to determine the research direction and research methods of this paper.The second part,through the interview method,this paper understands at the situation of front-line teachers' teaching of periodic law of elements,further induction "the element cycle law" this section content teaching present situation and the insufficiency: the situation teaching insufficiency,the chemistry history development content is more one-sided,the scientific experiment inquiry implementation is less,the teaching process lacks the cultivation of students' experimental inquiry ability.Based on the questionnaire survey of students' study status,this paper summarizes the current situation and existing problems of students' study of periodic law of elements: it is difficult to establish the knowledge model of "position-structure-property-function ";it has some difficulties in the concrete application of periodic law knowledge,such as: the concrete manifestation of metallicity and non-metallicity;using periodic law knowledge to judge and predict the properties of elements.Based on the above pedagogy theory research,through the comprehensive analysis of teaching materials,curriculum standards,examination syllabus,combined with the current teaching status quo and students' cognitive level,several effective teaching strategies are put forward.The third part,in order to carry out the practice of teaching strategy,based on the teaching idea of chemistry core accomplishment,designs the curriculum teaching design of element cycle law.Acquiring the feedback of classroom teaching effect,then combined with the examination results to evaluate the students' knowledge system.The research shows that the teaching mode of setting up the development of chemistry history and creating problem scenarios can improve students' attention in class,and increase students' learning efficiency.Paying attention to the establishment of chemical thinking model in teaching plays an important role in improving students' comprehensive thinking ability and implementing chemistry core accomplishment.The fourth part is the conclusion of this paper.Based on pedagogy theory,it puts forward teaching strategies based on chemistry core literacy,which can help students to improve their interest in chemistry learning and more easily establish the thinking model of "position-structure-quality",which is conducive to the cultivation of students' core literacy.Finally,the paper also points out the shortcomings of the research and looks forward to the direction of future efforts.
