Research On The Integrated Practice Of "Teaching,Learning And Evaluation" In Senior High School Chemistry Based On Core Literacy

The "Chemistry Curriculum Standards for General High Schools"(2017edition,2020 revision)emphasizes the important position of chemistry core literacy in the teaching of chemistry,and advocates teaching for the purpose of cultivating students’ core literacy.And with the advancement of the curriculum reform,the evaluation concept has changed,and the evaluation based on literacy is advocated.The integration of "teaching,learning and evaluation" is proposed under this background.Integrate evaluation into the teaching process,integrate with teaching,and promote the implementation of evaluation concept.Carry out the evaluation of daily chemistry learning in teaching,and attach importance to the important role of evaluation in the development of core literacy.The research content of this paper mainly includes the following parts:In the first part,through reading domestic and foreign literatures,the research status of the integration of "teaching,learning and evaluation" and the status quo of comprehension learning are sorted out,and the research purpose and significance of this research are clarified;The second part defines the concept of chemistry core literacy,comprehension learning evaluation,and the integration of "teaching,learning and evaluation",and introduces the theoretical basis of this research;The third part investigates the current situation of high school chemistry core literacy training and the current situation and difficulties of the integrated implementation of teaching evaluation,analyzes the survey results,and establishes evaluation ideas;The fourth part is based on the previous literature research and the investigation of the teaching status,to carry out the overall design of the evaluation system: to formulate teaching objectives according to the content design requirements of the curriculum standards,and to formulate evaluation objectives corresponding to the teaching objectives according to the requirements of academic quality.As well as the learning situation,carry out the integrated teaching design and practice of "teaching,learning and evaluation".Under the guidance of the evaluation goal,the six dimensions of comprehension learning are used as the evaluation carrier to design the study case to complete the evaluation system integrated with "teaching" and "learning".The fifth part is to choose the optional compulsory course of high school chemistry,"The Principles of Chemical Reaction",part of the content of the third chapter,according to the constructed system and the developed study case,to carry out five class hours of teaching practice,and to analyze the results.Finally,summarize and reflect on the previous research content,analyze the integration of "teaching,learning and evaluation" and construct the overall framework of evaluation,integrate evaluation into teaching,promote the development of core literacy through understanding learning evaluation,and quantitatively track The development of students’ literacy level provides feasible ideas for comprehensive and accurate chemistry teaching evaluation.
