The method used to record intellectual transaction in the Science Teaching Observation Schedule (STOS) is examined in the light of the theory of sampling methods. Concludes that STOS cannot give reliable quantitative data. Questions usefulness of continued analysis of STOS data. (Author/DS)

In response to criticisms of the reliability of the sampling methods associated with the Science Teaching Observation Schedule (STOS), the instrument's authors briefly review the rationale in developing the STOS and describe several studies validating the instrument. (DS)

Explores student-scientist partnerships (SSPs) that help students gain a unique understanding of both the content and the process of science. Discusses the potential of SSPs, the range of SSP activities, a strategy for national impact, the educational importance of SSPs, the research importance of SSPs, and technology as a facilitator.

Technology can be useful in physics classrooms, though teachers must be careful not to let technology remove students from first-hand experiences with nature through observation and experimentation. The paper examines how to enhance physics instruction using computers as graphing tools, for data collection, and as real-world simulators. (SM)
