The experiment of learning transfer Background To study the transfer of learning, there are two methods usually used: before and after learning method, continue learning method. There is a drawback of the learning method of before and after which can only examine the initial stage influence of A to B. Thus to examine the effects during the whole learning process, we replace the test of B by learning of B after the practice A, and it is called continue learning method. The specific arrangements of continue learning method are as follow: A and B are the two materials that have equal difficulty. Because of the same difficulty of A and B, merely considering if it is more easily to learn B after learning A or not can help to examine the influence of A to B. However, there are some limits of learning transfer study to conduct experiments with the materials that have the same difficulty. Therefore, if there are two same groups of participants so that we can study the influence of any kinds of learning to another learning. It is to say that the study scope can be enlarged. Thus the specific experiment arrangements are as follow: The experimental group: learn A fist, learn B then The control group: learn B.Then compare the results of the two groups learning B so that the influence of A to B can be gotten. If the two kinds of learning have different difficulty and the learning abilities of the two participants are different as well, the experiment of studying learning transfer can be arranged as follow：The first group: learn A first, learn B thenThe second group: learn B first, learn A then. Then combine the two results of first learning in the two group as C, and combine the two second learning results in the two groups as D as well. Compare C and D, the influence of the two kinds of materials to each other. Taking the needing time of reaching the same studying leve as index, if C D, it is positive transfer; if C D, it is negative transfer; if C = D, it means no influence
