The assessment method to be used for the
embedded audience analysis was another
concern. Although Keller (1987b) contended
that the full range of measurement possibilities
ranging from self-assessment to performance
observation and even electronic
measures of physiological characteristics can
be considered in audience analysis, the case
of CAI more or less limits one to self-assessment
for practical reasons. In this study, the
computer presented three questions at specific
internals in the program. The questions
asked learners to report their motivation with
respect to attention, relevance, and confidence.
The researchers judged that that
would be the most direct method and the eas-iest to use for most instructional designers.
However, as a way of partially compensating
for the weakness of self-report measures,
measures of performance scores on a quiz
were also used in conjunction with the motivational
self-assessment of confidence.
