Abstract This study investigated self-presentation bias in the self-reports of
teachers about their practices in six topic areas in educational technology
(Instructional Design, Assessment, Learner-Centered Instruction, Curriculum
Alignment, Attitudes about Computers, and Use of Computers with
Students). Subjects were 50 middle-school teachers. Data were collected using
a 30-item Likert-type survey containing five items per topic area. Teachers
responded to items in two forms: ‘‘what I do’’ and ‘‘what other teachers do.’’
Significant differences favoring the ‘‘I’’ form were obtained in three of the six
areas (Instructional Design, Learner-Centered Instruction, and Curriculum
Alignment) and on nine of the 30 items, indicating a rather strong self-presentation
bias. Responses were generally positive across both forms. Results
are discussed with implications for working with teachers and for using
additional assessment measures that complement teacher self-reports.
