High School Element Chemistry Teaching Design Based On The Integration Of "Teaching,Learning,and Evaluation" And Practice

The "2017 edition of the General High School Chemistry Curriculum Standards" regards the integration of "teaching,learning,and evaluation" as the basic concept of the chemistry classroom.For the first time,the three elements of teaching,learning,and evaluation are integrated and interconnected,aiming to cultivate students’ core chemical literacy and implement the fundamental task of cultivating morality and cultivating talents.The knowledge of chemical elements and compounds in high school mainly includes chemical experiments and other theoretical knowledge as the core content,which has negative characteristics such as a large system,complex intersection,and easy to learn and forget.In practical teaching activities,students usually adopt a single and mechanical memory method to learn and consolidate.However,teachers generally adopt the traditional "indoctrination" teaching method to carry out teaching,and do not organize relevant practical activities in the field of chemical experiment exploration on time,resulting in a lack of active thinking and hands-on practice ability,which invisibly brings unnecessary learning pressure and memory burden to students,Restrict the generation of students’ learning motivation and interest.In the face of various problems in the teaching of high school chemical elements and compounds,it is necessary to promptly establish a high school element and compound teaching design and practice based on the integrated concept of "teaching,learning,and evaluation",effectively improving the quality of teaching and the development of subject core literacy.The author used literature research methods to sort out relevant literature on the integration of "teaching,learning,and evaluation" and the teaching of high school chemical elements and compounds.Using three methods: questionnaire survey,interview survey,and classroom observation,the author fully understood the current situation of the implementation of "teaching,learning,and evaluation" integration in a high school chemistry classroom teaching in Xing’an League.After the above investigation and analysis,a teaching design for high school chemical element compound content based on the integrated concept of "teaching,learning,and evaluation" was proposed,and classroom teaching practice was conducted on it.Subsequently,through interviews and student performance analysis,the feasibility and real effectiveness of this teaching design and practice were confirmed.The conclusion is as follows:(1)Through teachers’ questioning,commenting,questioning,as well as students’ self-evaluation and mutual evaluation,as well as various evaluation forms such as classroom testing and homework,the three elements of "teaching,learning,and evaluation" are fully integrated to jointly achieve the practical goal of "evaluation in teaching,promoting teaching through evaluation,and promoting learning through evaluation".During this process,students should effectively understand the achievement of their learning goals based on the true feedback of the evaluation results,further optimize their internal motivation for learning,and stimulate their subjective initiative in learning.They should focus on developing students’ core competencies in the field of chemistry,and comprehensively improve the quality of education and teaching;(2)From the analysis of student performance and interviews,it can be seen that the design and practice of high school elemental chemistry teaching based on the integrated concept of "teaching,learning,and evaluation" not only has a certain incentive effect on teachers’ "teaching",but also has a great traction effect on students’ "learning".The steady implementation and vigorous promotion of the integrated concept of "teaching,learning,and evaluation" have effectively promoted the improvement and progress of students’ learning abilities,and effectively promoted the formation and cultivation of core competencies in the chemistry discipline.In summary,the integration of "teaching,learning,and evaluation" has become an important "trend word" in current curriculum reform.How to break away from the inherent teaching mode and how to truly implement students’ core literacy have become the core topic of common concern for us educators.Therefore,in the actual teaching process,fully utilizing the high school element chemistry teaching design and practice based on the integration of "teaching,learning,and evaluation" can effectively implement the integrated concept of "teaching,learning,and evaluation",break through various persistent problems in current teaching work,and in the future era of artificial intelligence and complex information environment,be able to grasp the direction and self navigate.This is not only the inherent meaning of core literacy,but also the proposition of the times.
