The Influence Of Learning Domain Knowledge And Sample Design On Solving Percentage Applied Problems About Concentration

Worked-example learning refers that learners learned the relevant knowledge,skills and strategies through examples.As an important way of autonomous learning,worked-example learning has become the main way of teaching and students'autonomous learning.On the basis of previous studies,this research focused on the influence of familiarity with learning domain on learning performance in the double-content examples.We have carried out two experimental studies on the application of the percentage of five grade students through the worked-example learning.The first experiment is to allow two homogeneous subjects to learn double-content examples of familiar domain knowledge and unfamiliar domain knowledge.60 subjects were selected by a pre-test out of the fifth grade students of a common primary school in Dalian.After the learning procedure,we analyze the results of their transferring performance.The results show that:the subjects who were familiar with the learning domain knowledge performed significantly better than those who were not familiar with the learning domain knowledge on near-transfer performance;the subjects who were familiar with the learning domain knowledge performed significantly better than those who were not familiar with the learning domain knowledge on far-transfer performance.In the second experiment,we used the examples that were designed by labeling method and the common examples as two different learning materials,60 primary school students in the fifth grade were selected as participants.Results show that:compared with the students who learned the common examples,students who studied the examples designed by labeling design method performed better on the transfer scores of the learning domain knowledge,the transfer scores of exemplifying domain knowledge,as well as total transfer scores.From the above two experiments,we draw the following conclusions:(1)there is a positive correlation between the familiarity of learning domain knowledge and the acquisition of exemplifying domain knowledge.That is the more familiar the learning domain knowledge is,the better the learning effect of the knowledge in its sample domain.(2)the sample design of labeling method can effectively improve the learning domain knowledge,exemplifying domain knowledge and the whole double-content of example.
