A Practical Study Of Jigsaw In The Teaching Of History Of Biological Science In High School

Two thousand and fourteen In,the Ministry of education developed and printed the opinions on comprehensively deepening the curriculum reform and implementing the basic task of establishing morality and cultivating talents.Centering on the fundamental problem of "establishing morality and cultivating talents",it put forward the concept of core literacy,which is clearly required to be implemented in practice.In 2018,the Ministry of Education issued the general high school chemistry curriculum standard,marking the beginning of a new round of curriculum reform,and the five core literacy of chemistry Officially landing,replacing the three-dimensional target.In recent years,the investigation of core literacy is more and more obvious in the chemical test questions.However,the research on the connection between core literacy and chemistry test is still in its infancy,so it is very urgent and necessary to study the chemistry test in Senior High School under the background of core literacy.In this paper,the first chemical simulation test and the second chemical simulation test after the second round of review in 2017-2019 in Harbin area are taken as the research objects.Based on combing,analyzing and determining the concept of chemical core literacy,this paper uses literature research,statistical analysis,case study and other research methods to carry out six sets of chemical simulation test papers in Harbin area Research,including the distribution of knowledge points,question type,score,examination of literacy ability and analysis of the embodiment of literacy of chemical simulation questions.According to the statistical chart,the paper analyzes the five core literacy questions: macro analysis and micro analysis literacy,change concept and balance ideological literacy,evidence reasoning and model cognitive literacy,scientific exploration and innovation awareness literacy,scientific attitude and social responsibility Carry on the characteristic analysis,and carry on the analysis to the typical test question which manifests the core accomplishment,and interpret the core accomplishment's embodiment in the simulation test question in detail.According to the results of statistics,this paper summarizes the core literacy of chemical simulation test in Harbin.Then,the paper compares and analyzes the characteristics of core literacy in Harbin Senior three chemistry simulation test and the national second volume test.According to the research on chemical simulation test questions in the past three years,the teaching strategies for cultivating core literacy are put forward,such as situational course content,reflecting chemical practice,focusing on knowledge integration,grasping core concepts,increasing experimental teaching,providing students with opportunities for practical learning,focusing on the raising of problems,and cultivating the ability to collect data,etc.Finally,this paper summarizes the research results,reflects on the deficiencies in the research process and makes a prospect for the future research of this topic.
