Although technological innovations have been widely adopted in elementary schools, efforts to implement these have generally not been successful. Past research on innovation has largely ignored the social context in which implementation occurs. This research examines how the implementation of the microcomputer is affected by the traditional social…

This paper reports the results of a Monte Carlo investigation of Type I errors in the single group repeated measures design where multiple measures are collected from each observational unit at each measurement occasion. The Type I error of three multivariate tests were examined. These were the doubly multivariate F test, the multivariate mixed…

A random sample of 113 members of the American Vocational Education Research Association (AVERA) was surveyed to obtain baseline information regarding AVERA members' perceptions of statistical significance tests. The Psychometrics Group Instrument was used to collect data from participants. Of those surveyed, 67% were male, 93% had earned a…
