Macro Identification And Micro Analysis Of Chemistry In Senior High School

At the end of 2017,the new senior high school chemistry curriculum standard was officially issued,and the curriculum standard made clear requirements for the depth and breadth of the academic content.In terms of the breadth,the core accomplishment of the chemistry discipline was divided into five dimensions:"macro identification and micro exploration","changing concepts and balancing thoughts","evidence reasoning and model cognition","scientific inquiry and innovation consciousness",and "scientific attitude and social responsibility".In terms of the depth,the academic quality was divided into four levels.This paper mainly studies the evaluation and strategy of "macro identification and micro exploration" core literacy,which emphasizes that chemistry should not be studied from a macro or micro perspective,but the relationship between macro phenomena and micro structure should be identified,explained,analyzed and inferred to form the chemical concept that structure determines nature and nature reflects structure.This is very beneficial to help students learn chemistry,and also to learn other subjects and contact production and life aspects often get twice the result with half the effort.Through background analysis,theoretical reference and definition of relevant concepts,this paper aims to establish an effective evaluation system.The establishment of the evaluation system first represents relevant knowledge of macro identification and micro exploration,and then carries out a detailed analysis of macro identification and micro exploration.The ability performance of students will be judged from low to high in terms of learning ability,cognition mode,cognition Angle,symbol representation,and so on.According to the evaluation system,the paper reorganizes and adapts the test questions of different levels,and tests the level of core literacy of the students of grade two and grade three in a high school in yanji city through the test questions.By evaluating the core quality of "macroscopic identification and microcosmic exploration"and summarizing the interviews with first-line chemistry teachers of senior two and three grade students through the evaluation mode,it is concluded that the overall level of macro and microcosmic combination of senior high school students is above the average level,and students pay more attention to the learning of chemical knowledge,but ignore the thinking mode and quality brought by this knowledge and apply it to the study of life and other disciplines.In view of the above problems,this paper puts forward three cultivation strategies:combining the curriculum standards,grasping the teaching content again,paying attention to chemical experiments,enlightening scientific thinking,implementing the integration of teaching,learning and evaluation,and effectively carrying out teaching feedback.Hope can throw a brick to attract jade,cause more scholar and the thinking of educational job.
