185 secondary teachers of mathematics responded to a questionnaire asking them to rate their competence with and classroom use of databases, spreadsheets, Logo and basic, In addition they were invited to offer curricular justifications for each of the four pieces of software, Overall there was a nide spread of competence with, and classroom use of, all four pieces of software, Databases were perceived to have limited curricular value with justifications focusing on narrow aspects of data handling, Logo was viewed positively with justifications addressing issues such as motivation and covering a range of geometric al topics, Spreadsheets were seen as the most versatile software with justifications being spread across a range of curriculum areas, with few exceptions basic was dismissed as being of little use, Competent teachers who used software regularly tended to have shorter lengths of service, better qualifications and were more likely to be male than female, The converse tvas also found to be true.

This paper describes a basic microcomputer program that computes all pairwise comparisons of means after analysis of covariance using the Tukey-Kramer test. Input to the program consist of the means of the covariate, the adjusted criterion means, the sample size, mean square error from a one-way analysis of covariance, and the 95th percentile point on the Studentized range distribution.

A basic computer program is described which computes the Stuart-Maxwell test with its chi-square value and associated probability level. Following a significant chi-square test, the user has the option of performing multiple comparisons using McNe-mar"s test for the significance of change.
