In February, 1994, a written questionnaire was sent
to the 197 workshop participants from the summer of
1993. The response rate was 64%. There were 113 usable
responses; 2 questionnaires were returned too late
to be included in the analysis; and 12 questionnaires
were returned either for incorrect address or because
the addressee had not actually attended the entire
workshop. Results of the first nine questions were
compiled and the open-ended responses were analyzed
and categorized.

Ninety-nine of the 113 participants who responded
to the questionnaire indicated on the questionnaire
that they would be willing to be interviewed by telephone.
After the analysis of the written questionnaires,
phone interview participants were sought whose responses
indicated either a dramatic change in their view of
teaching calculus, or a resistance to change; and
whose responses indicated careful thought about the
impact of the workshop. This initial group numbered
thirty-six. During the first week in May, 1993, an
attempt was made to call all thirty-six people to
set up appointments for interviews. Ten of the thirty-six
were either unreachable or were unable to be interviewed
in the available time period. One additional person
made an appointment and then was unable to keep that
appointment. Thus, twenty-five people participated
in the telephone interviews. An attempt was made to
interview participants from each workshop as well
as participants from each of the four institution
types. |
