Enlightenment： this knowledge helps avoid misunderstanding of educational philosophy, which is not only a type of theoretical philosophy, but also a practical philosophy; teachers need to construct a proper philosophy of personal education of their own and enhance their professionalism and specialism while improving their humanistic quality and professional sentiment; great efforts should be made to create an educational community to exert the influence of philosophy of public education, and to promote the healthy development of educational activities.展开更多

Then the relation between the three-order form invariance and the three-order Lie symmetry is discussed and the sufficient and necessary condition of Lie symmetry, which comes from the three-order form invariance, is obtained. Finally a three-order Hojman conserved quantity is studied and an example is given to illustrate the application of the obtained results.展开更多

In this paper by using adjoint operator method, normal forms of order 3 and 4 for nonlinear dynamical system with nilpotent linear part and Z(2)-asymmetry are computed. According to normal forms obtained, universal unfoldings for some degenerate bifurcation cases of codimension 3 and simple global characterizations, are studied.展开更多

Semi-structured interviews were conducted online with some student teachers （n = 10） and teacher educators （n = 10） at the university to identify their personal viewpoints, experiences and concerns regarding integrating the Internet into this teacher education context. For triangulation purposes, content analysis was conducted on 12 online documents. Results reveal some difficulties, challenges and concerns related to the process and some new forms of literacy needed for this context. Based on this, some guidelines are suggested for integrating the Internet into pre-service EFL teacher education programmes with special reference to the Egyptian context.展开更多
