A coactive sign system for children who are dual-sensory impaired.

The SKI*HI Institute developed a system of coactive signing to help alleviate communication and instructional barriers for children who are dual-sensory impaired (deaf and blind). The system also can be used to help children who are severely multihandicapped learn how to communicate. The system includes optimized coactive signs that are functional, easy to feel, easy to relate to the referent, and easy to make, and it also includes techniques related to effective coactive sign use. The coactive sign system is illustrated on a series of video tapes that has been field tested and produced and is being disseminated throughout the United States and Canada.     

Research on teaching in physical education.

This article reviews research on teaching in physical education. I first consider research methodology employed in this area and then examine research related to instructional effectiveness, classroom ecology, and cognition and decision making. Conclusions and future directions are then presented that have implications for researchers, teachers, and teacher educators.     

Seizing the moment: scientists' authorship rights in the digital age

The American Association for the Advancement of Science carried out a study on intellectual property and electronic journal publishing with the aim of identifying those aspects of the intellectual property regime that facilitate or constrain the effective development of electronic scientific publishing. This paper summarizes the conclusions reached, emphasizes the continuing need to maintain the legal framework offered by copyright law, but makes recommendations both for its modification and in its application to ensure that the potential benefits of electronic publishing are fully realized.
