Assumptions
and Limitations |
Assumptions:
1. It was assumed that participants would understand the language of assessment
and how to respond correctly to the questions.
2. It was assumed that participants would understand the structure and scope
of the study and its implications.
3. It was assumed that all participants were objective and accurate in self-assessing
the effectiveness of their learner assessment strategies and methodologies.
4. It was assumed that participants were objective about their own professional
practice.
5. It was assumed that the data would reveal the use of authentic assessment.
6. It was further assumed that participants would complete the survey within
the time frame given.
Limitations of the study:
1. Response burden is considered to be a primary limitation when collecting
survey data. Response burden is usually quantified in terms of how long the
survey takes to complete. Other aspects of response burden include how difficult
it is to provide the desired information and how sensitive the respondent is
about providing the information. As Zukerberg and Lee (1997) suggest, “Completing
a survey is often a novel experience for respondents” (p. 1). In order
to lower response burden, careful attention was given to the following aspects
of the survey: design and implementation of the survey instrument, explanation
of terms, clear instructions for completion, length of survey, time required
to complete the survey, anonymity of respondents, and password protection.
2. The audience of participants was limited to members and conference attendees
of academic organizations whose primary focus is the integration of technology
into instruction.
3. The participants were limited to instructors who teach introductory computer
science, information technology or similar computer applications courses either
totally online or with some online components.
4. The participants were further limited to instructors within the above groups
who volunteered to complete the online survey after an initial e-mail solicitation
to organization members.
