Its performance is similar to MS Windows. It works well under demands of more saving resources and automatization, like memory of system. An approach to install/update software automatically on embedded platform was proposed. This approach derives from above feature based on embedded environment with Linux OS. Configurations of files related to this feature were introduced. An example in practice was given to realize this approach from universal serial bus (USB) memory disk when USB disk is available.展开更多

The prohibit-word table with position information has been designed. The improved Maximum Matching-Minimum Backtracking method has been researched. Moreover it has been studied on improved indexing algorithm and application technology based on rules and thematic concept word table.展开更多

Classroom observation, focus group interviews, and questionnaire were used to （a） explore how the student teachers engaged in the practices of peer teaching and learning and reflected on their relevance to their own future teaching careers and （b） identify the major benefits and challenges of peer teaching from the students＇ perspectives. Most of the students actively engaged in peer teaching during the course and considered it as a strategy that they might later use in their teaching. Issues such as awareness of teaching elements, opportunities for peer learning, cultural diversity, and English as a medium of instructions brought both benefits and challenges for students in the process of peer teaching. The study points to a research agenda for pre-service teacher education for autonomy that focuses on the long-term impact of students＇ experiences of a range of pedagogical strategies for autonomy on their future teaching.展开更多
