While science classes are believed to be interactive learning environm
ents, offering varied ways for students to learn, some experts believe
that learning disabled (LD) students should be monitored closely in s
uch settings because of difficulties adjusting to the social, behavior
al and academic demands. The purpose of this paper is to determine whe
ther LD fourth and sixth graders show difficulties adjusting to the de
mands of their mainstream science classes and to investigate two means
of assessing LD students' functioning in these classes: paired questi
onnaires for teachers and students and a science curriculum-based asse
ssment (CBA). Subjects include 31 fourth graders (9 LD) and 38 sixth g
raders (13 LD). Results show that the LD students had significant weak
nesses on some subtests of the science CBA relative to their peers; ad
ditionally, they rated themselves and were rated by their teachers sig
nificantly more negatively than their Non-LD peers. These results sugg
est the potential value of monitoring LD students in mainstream scienc
e classes. Case studies of LD students reveal mismatches in the percep
tion of the student and teacher regarding the student's adjustment and
classroom habits. Examination of these case studies is used to sugges
t ways in which the collaboration of student and teacher as well as re
gular and special education teachers might aid the student.
