We selected from 222 students at first grade in a primary school as subjects. A One to One intervention was given in the subjects by using self-made program computer programs. This study is composed of two experiments. The first experiment discusses the effect of self-explanation which guided by different direct instruction in problem solving on procedural learning, procedural transfer and conceptual understanding. The purpose of this experiment was to test whether self-explanation can promote transfer and which is the most the most effective combination of self-explanation and instruction. The second experiment, based on the results of the first experiment, compared the effect of self-explanation of different types in problem solving on procedural learning, procedural transfer and conceptual understanding. There are two methods: explain aloud, explain without voice. The purpose was to compare which effect is better?

8Ps for native and NaBH〓 chemically modified reaction centers, and the transfer process from H〓 to the final electron acceptor Q〓 occurs in about hundreds of picoseconds. On the other hand, the energy transfer from excited B was obviously slowed down in the pheophytin-exchanged RC. By considering the change of free energy of ion pair P〓Phe〓, it could be expected there might exist alternative pathway of charge separation and electron transfer in pigment-exchanged reaction center. In addition, the influence of acid environment on the ultrafast dynamics of reaction center was also experimentally observed, which shows an evident difference from that of in native RC, and further investigation should be carried out to elucidate the origination.
