Worked Examples Learning Of The Change Rules Of Gas And Functional Relationship By Analogical Reasoning

There are the same variation regularity and functional relationship in the different thing.According to the basic principle of analogical reasoning to solve the problem,whether the functional relationship between two different things use analogical reasoning?In order to investigate whether students can grasp the functional relationship by learning worked example of the change rules of things,then analogical reason about the relation of function,and promote the learn about the change rules of other things,which contains the same functional relationship,we conduct two experiments,selecting the first grade of junior high school students as participants.Experiment 1 adopted the virtual database of mobile phone prices change rules as worked-examples materials,investigate the effect of linear function and inverse proportional function by worked-examples learning.Experiment 2 adopted the database of the gas isobaric,isothermal and isothermal variations as worked-examples material,investigate the positive impact of the gas isobaric,isothermal and isothermal variations after mastering the functional relationship.(1)experiment 1 investigate the effect of linear function and inverse proportional function by worked-examples learning,selecting 240 students in the first grade of junior high school,using two factors random block design between subjects.The results were the following,whether it was in the near-migration test,or far-migration test,transfer performance of the sample group was significantly better than control group.There was no significant difference in two types of functional relationship.(2)the experiment 2 investigate the effect of the state variation of gas whether or not students learn to linear function and inverse proportional function,using two factors random block design between subjects.The results were the following,in addition to the effect of the inverse function sample to learn,not learn between the far-migration is not significantly difference,however,in other migration test,the transfer performance of the sample group was significantly better than control group.lt is suggested that the effectiveness of learning from worked-examples with linear function and inverse proportional function for the rules of gas isobaric,isothermal and isothermal variations.
