Research On Teaching Practice Based On The Core Literacy Of "Evidence Reasoning And Model Cognition"

Today is a new era of all-round development,and the development of the new era has a clearer and clearer understanding of cultivating high-quality,high-standard,and high-profile socialist successors.The rapid development of society has caused a huge change in the demand for talent training.Citizens need to have the core literacy to adapt to social development to be able to cope with this change.In recent years,groups of educational researchers in my country have been actively exploring ways to cultivate core literacy to cultivate students with the key ability to adapt to future social development,so as to meet the needs of talents with comprehensive qualities for social development.In 2016,the promulgation of "Core Literacy for Chinese Students’ Development" means that my country’s continuous promotion of core literacy education will enter a new process.The 2017 edition of "Chemistry Standards for General High Schools" highly condenses the core literacy of chemistry,and the promulgation of the new curriculum standards is like a The direction mark points out the direction for the development and implementation of students’ core literacy in chemistry.Among them,"evidential reasoning and model cognition" is one of the five dimensions of the core literacy of chemistry.The literacy is an important method of thinking in chemistry.It occupies a relatively important position and is also a research hotspot of many scholars and front-line teachers.At present,most of the research on core literacy is biased towards theoretical research.Although the new curriculum reform has achieved certain results,there are not many practical researches that really implement the core literacy of "evidential reasoning and model cognition" into middle school chemistry classrooms.Therefore,how to implement the core literacy is the focus of current research,so it is very necessary to enter the middle school classroom to discuss the teaching practice research to promote the cultivation of the core literacy of "evidential reasoning and model cognition".This research adopts the methods of literature analysis,questionnaire survey and interview.In-depth understanding of the research status of core literacy,"evidential reasoning and model cognition" and other theories,and on-the-spot investigation of the current situation of the core literacy training of "evidential reasoning and model cognition" in high school classrooms.The survey results show that most chemistry teachers do not have a thorough understanding of the connotations of evidence reasoning and model cognition;most chemistry teachers do not pay much attention to the cultivation of evidence reasoning and model cognition;Some students lack a correct understanding of evidence reasoning and model cognition;the current situation of evidence-based reasoning and model cognition literacy training in middle school classrooms is generally average.Based on the analysis of the survey results,guided by constructivist learning theory,meaningful learning,and inquiry-based learning theory,the content of high school chemistry is sorted out,and teaching cases suitable for cultivating students’ evidence-based reasoning and model-based cognitive literacy are selected.The data of practical research in this paper mainly come from questionnaires and examinations,and focus on comparative research on the changes of students’ learning styles,academic performance and the formation of the core literacy of "evidential reasoning and model cognition".The practical results show that the classroom teaching practice based on "evidence reasoning and model cognition",1.is conducive to helping students change their learning methods,and is more conducive to helping students form scientific thinking in learning chemistry;2.is conducive to improving students’ problem-solving ability,to promote the improvement of chemistry performance;3.Help to enhance students’ awareness of evidence and model awareness,and effectively implement the core literacy of "evidence reasoning and model cognition".
