Abstract Research Methods Tutor (RMT) is a web-based intelligent tutoring system designed for use in conjunction with
introductory research methods courses. RMT has been shown to result in average learning gains of .75 SDs above classroom
instruction in traditional college environments. However, a primary goal of the RMT project is to provide greater access to
tutoring for students without access to traditional one-on-one human tutoring. Therefore, we further tested RMT’s effec-
tiveness at a university that enrolls primarily non-traditional students. Although we again found evidence of RMT’s effec-
tiveness, a few key outcome differences between traditional and non-traditional environments emerged, including percep-
tions of the pedagogical agent and access to the system.

1. Introduction
Computing technologies, particularly those that allow
students convenient access to learning resources, are infil-
trating every aspect of the educational system. Textbooks
routinely come with online student resources, and many
instructors regularly assign online or computer - based
homework to enhance the classroom learning experience.
One of these computer-based technologies, intelligent tu-
toring systems (ITS), seeks to mimic the benefits of
one-on-one human tutoring. Expert human tutoring is be-
lieved to be among the most beneficial learning techniques.
Bloom, for example, found that a successful human tutoring
situation can enhance learning by up to 2.3 standard devia-
tions over classroom instruction alone[1]. In contrast to more
didactic approaches, such as lecture, textbook learning, or
websites that mimic a traditional textbook layout, tutoring
allows students to engage in a dialog that helps them to as-
sess their current levels of understanding and to work coop-
eratively to increase levels of knowledge[2-7]. The extent of
the student’s engagement in this dialog is correlated with the
student’s learning outcomes[8-10]. An ITS that uses the
techniques employed in expert human tutoring, therefore,
could provide access to this powerful learning technique
without the drawbacks of human tutoring, which include the
cost, the time involvement, and the inconvenience of coor-
dinating schedules. Due to the challenges faced by many of

today’s students, including childcare, work schedules, and
transportation[11], ITS have the potential to make vast con-
tributions to effective teaching and learning.
A number of successful ITS have been created and tested
to date. For example, Koedinger and colleagues[12] con-
ducted a large-scale study of the effectiveness of PAT (the
PUMP Algebra Tutor) in conjunction with a high school
algebra curriculum. They found that students who used the
system scored 100% higher on basic skills tests than those
who did not use the system. In laboratory-based tests, an-
other ITS, AutoTutor, increased students’ scores by one
standard deviation above reading a textbook alone[13].
ANDES, an ITS used in undergraduate physics courses, has
also been associated with significant learning gains for stu-
dents who use the system in lieu of pencil-and-paper based
homework[14].
Research Methods Tutor (RMT) is a dialog-based ITS
created to increase student learning in introductory under-
graduate psychology research methods courses. Most psy-
chology programs require at least one course in research
methods[15]. Research methods courses, however, tend to be
difficult for psychology majors due to their applied, techni-
cal, and largely quantitative nature. In addition, research
methods courses require students to engage in critical
thinking, which is generally a skill that undergraduate col-
lege students are in the process of developing[16]. RMT is
designed for use in conjunction with traditional coursework
and is available online, making it convenient to use at any
time of the day without cost. It consists of five topic modules
that coincide with typical topics from psychology research
methods - ethics, variables, reliability, validity, and experi-
mental design. Each RMT topic module is assigned after the
