Describes a chemistry software program that emulates a modern binary gradient HPLC system with reversed phase column behavior. Allows for solvent selection, adjustment of gradient program, column selection, detectory selection, handling of computer sample data, and sample preparation. (MVL)

Responds to Eisner's discussion of the nature of research and the place of qualitative research. Advocates increased emphasis on the true experiment in educational research to provide evidence of the usefulness of educational practices. (SLD)

Explores the nature of educational research, replying to Knapp's comments on the role of qualitative research. Suggests that the "true" experiment is very hard to conduct in educational research and discusses what validity means in the educational research context. (SLD)

The Multiple Option Observation System for Experimental Studies (MOOSES) is a flexible data collection and analysis package for applied behavioral research that addresses the needs of researchers interested in live coding of observational data. MOOSES allows the researcher to design a coding system for a particular research question. General types…
