Student Perceptions
of the Use of a Personal Response Device in a Large Lecture Class
Summary
In a general education plant pathology class we used personal
response devices (IClickers, www.iclicker.com)
that allow students to answer multiple-choice questions privately
to learn about students, conduct opinion polls, enhance class
discussions, review quiz questions and assess comprehension of
material. Students reported that the devices increase enjoyment,
learning and participation, but generally did not support their
use to monitor attendance or assign credit for correct responses.
Over a semester, instructors learned to use the system more effectively.
Introduction
Electronic personal response systems with devices to collect,
aggregate and display response data from students were first developed
in the 1990s (1). While the first system was devised in order
to revitalize lecture-based courses, advances were sparked by
two studies by Halloun and Hestenes (5,6) that showed that college
physics students were passing introductory physics courses without
learning Newtonian concepts. The system allowed students to think
more deeply, establish positions, and defend their decisions.
Viewing aggregate data showed the students where they stood compared
to their peers and indicated possible misconceptions to the instructor.
Researchers both within and outside of physics have reported that
their classrooms were happier, more lively environments when electronic
student response systems were used (1,3,4) Students report many
positive attributes of personal response systems, including anonymity,
being able to check their understanding, and encouraging participation
(2). In this study, we explored the usefulness of personal response
devices in a 75-student plant pathology course.
Materials and Methods
This study was conducted for two semesters in a 75-student general
education plant pathology class (Plant Pathology 200 - Plants,
Pathogens, and People). Student surveys were conducted twice each
semester: early (the second or third week of class) and late (the
last week of class). Each survey consisted of five short-answer
questions, followed by a space for additional comments. In Fall
2004, 68 students completed the early survey and 60 completed
the late survey. In Spring 2005, 59 and 58 students completed
the early and late surveys, respectively.
IClickers were distributed to students on the first day of class.
They were used for several purposes throughout the semester:
• to gather information about the students’ backgrounds
and level of knowledge
• to share students’ knowledge
• to poll students’ opinions
• to test knowledge and comprehension of course material
• to review on-line quizzes
IClicker questions with two to five answers were posed at various
times during each 80 minute class period.

Results
Results of the early survey (Table 1) indicated that >90%
of the students enjoyed IClickers and >85% believed the devices
enhanced their learning. While most students reported that the
IClickers were being used at a good frequency during class, about
1/5 thought they could be used more. More students opposed the
use of IClickers to either monitor attendance or to assign credit
than favored either of these uses.

Results of the late survey (Table 2) were similar to those of
the early survey for enjoyment and interest. The frequency of
use of the IClickers improved over the course of the semester,
with >90% responding “just right”. About 3/4 of
the students reported that they used their IClickers “often”,
but regardless of whether or not they used their own device, 95%
reported that use of a student response system increased their
participation in the class.

Conclusion
Use of personal response devices increased student participation
in a relatively large class. They also helped to make student
learning more visible to the instructors, and thus enabled us
to improve our teaching.
