We investigated the influence of the learning disability label on performance expectations among prospective teachers in Germany. Using an experimental design with 276 participants, they read a description of a student with academic problems, with only the experimental group having the student labeled as having a learning disability. Results revealed no significant main effect of the learning disability label, but prospective special education teachers had partially lower performance expectations than regular education teachers.
We had 186 pre-service teachers visually analyze single-case graphs, representing an intervention effect, a baseline trend, both, or no change at all. The presence of a baseline trend increased type I errors from 5% to 25%. Inter- and intra-rater reliabilities were low, particularly for graphs including a baseline trend.
