Investigation And Comparative Study On The Study Of Physical "physical Changes" In Urban And Rural Junior High School Students

In the science testbook,for primany grade3,The design of "change of state" emotional learning questionnaire preparation,learning skills and experimental study for the The learning adaptability of students is to the original level of knowledge or psychological development of new learning,is a dynamic process of development;different age stages,various internal factors influence each other,and their psychological maturity level and psychological development level have obvious differences,these differences are necessary for effective learning the conditions.Therefore,education should provide students with learning preparation.There is a chapter named state transformation belongs to coiiection of phenonena.in thermal knowledge in junior high school physics which is closely related to daily life.Most of studengs are familiar whth it,But there may be some differences between urban and rural areas due to the temperature in the same season in urban and rural areas.So,urban studengts?learning readness is different from rural studengts?learning readiness to some extents.In this paper,the writer sets a konowleage background based on the third chapter state transformation in the grade 8 physics textbook in the current PEP edtion,and the change of tempreture and daily life related to state transformation of natural phenomenapreparation,designing a questionnaire for operation skils in experiment.,On the basis of questionnaire,the writentries to make a comparative study of data information,draw the following conclusions.In preparation for the emotional learning: the county junior high school students can adapt to the learning of junior middle school and a good life,the classroom questioning almost no one showed very hate state;most urban and rural middle school students feel physical are very useful for life,love do the experiment is to "change of state" chapter study.But think that physics is difficult to(mainly used in conversion of physics formula and mathematical knowledge.).In preparation for the knowledge learning: nearly eighty percent of the urban and rural middle school students have some understanding of the factors influencing the liquid evaporation speed,the county junior high school students in the increase of the liquid surface area and improve the temperature of the liquid of these two aspects of comparative advantage,the Township Middle School Students in speeding up the liquid surface above the air velocity on the advantage;almost all of the urban and rural junior high school students on the ice and candles at different points in the melting process can not find;more than 2/3 of the urban and rural middle school students think that "mist" is liquid,white gas liquid;more than 2/3 of the urban and rural junior high school students of small water droplets appear on the beverage bottle is how to clear,can feel what is going on(melting but basically,the boiling point of the liquid typos)not what consciousness;more than half of the urban and rural middle school students think the process of water ice in the warm The ice melting temperature decreased,water and water boiling up;the temperature of the county junior high school students' perception,understanding and use of the thermometer and the mothballs understanding is more obvious than the township middle school students is dominant;the township middle school students on "the snow is not cold,cold snow" the scene more familiar in view of this situation,can write a lot of your feelings and thoughts,the township middle school students more than eighty percent of the solid form of water was very familiar with,and that "dew" is a liquid substance.In the experimental operation skills: the thermometer for understanding and using and reading,can the correct operation of the county junior high school students than the township middle school students;seen and used alcohol lamp,can ignite and extinguish the right light alcohol county junior high school students than the township middle school students,for the heating of the object with the alcohol lamp,know for heating with the outer flame of urban and rural middle school students less than 1/3,which is also the county junior high school students of junior high school students have seen and used the excess of villages and towns;urban and rural middle school students in less than 1/3,the proper use of test tube for heating liquid is less than half the urban and rural junior high school students,but there are more than the county junior high school students in the township middle school students;seen and used the beaker county junior high school students than Township,but the proper use of the beaker heating of the liquid Township junior middle school More students than the county;the combination of alcohol lamp and beakers,the township middle school students can correctly operate much more than the county junior high school students.
