Quality Analysis And Improvement Strategy Of Science Exercises Under The Framework Of Pisa2015

Pisa is an international student assessment project organized by Organization for Economic Co-operation and Development(OECD)to carry out the comparison of different countries students' academic level.PISA enjoys a high reputation and recognition in the world,known as “Education World Cup”.The test key of Pisa2015 evaluation is science.The evaluation target system and testing level is very consistent with the test requirements and science literacy dimension that put forward by China's current science curriculum standard.The evaluation target,test question types,proposition strategy are worth using for reference.I analyze the quality of science exercises in Ningbo and put forward the improvement strategies based on PISA2015 testing framework and proposition technology,in order to compile high quality science exercises in accord with the actual requirement of science teaching and evaluation.Based on the analysis of the Pisa2015 evaluation framework and these years' senior high school entrance examination questions in Zhejiang province,I put forward some improvement strategies of science exercises:I excavate exercise sources from the real life situation;pay attention to frontier science and technology news for a wide range of collecting material;explore the unexpected joy of the experiment,to broaden the exercise situation;encoding clear detailed points to the standards;accept diverse answers,protect students' spirit of innovation.I use these five strategies to try to compile some exercises which come from real life,hope to prepare science exercises in our country in virtue of the application of exercise compilation Pisa testing used,to develop more exercises that really test students' ability to adapt to social life,in order to meet the needs of practical teaching.This paper argues that good exercise should come from life situation,finally in the service of life.Pisa question well reflect the characteristics.Pisa2015 science assessment framework and Pisa2015 test gives us a lot enlightenment and reference about junior middle school science exercise formulation.It suggests mining exercise sources from the real life situation,preparing clear answer,accepting diverse answers,then students' innovation spirit and logical thinking ability will be cultivated.
