This document summarizes the development of an intelligent tutoring system called the Accounting Tutor. It describes the key components of the system, including: (1) a student modeler that tracks a student's knowledge, problems, and learning strategies; (2) a problem solver that solves accounting problems; (3) a diagnoser that identifies discrepancies between a student's work and the ideal solution; and (4) a tutor that provides feedback, instruction, and problems based on the student's needs. It also describes an accounting platform and user interface to facilitate problem solving. The goal is to test the system in a classroom and evaluate its effectiveness in helping students learn accounting concepts.
This paper presents a model of Questions & Answers (Q&A) learning where students are the ones that ask and also answer questions, as a method to increase and reinforce knowledge.
Computers are a familiar sight in classrooms in the 21st century, and technology has been used to streamline many educational tasks. CAL started in the 1950s and 1960s mainly in USA. Term often used interchangeably with Computer-Based Instruction (CBI), Web Based Instruction (WBI), Computer-Assisted Learning (CAL), Computer-Enriched Instruction (CEI), and Web Based Training (WBT). Logo project was the first CAL system that was based on a specific learning approach.

Initial Identification
When you hear the word "college," you might picture students hanging out in their dorm rooms or packing into large lecture halls for their studies. However, when more and more learning methods are made possible by technology, that representation is dated more and more. Indeed, the popularity of online and distant learning among college students has consistently grown, but does that indicate it's a good fit for you? To help you respond to that question, spend some time contrasting traditional versus online schooling. Since both traditional and online learning have benefits and drawbacks, students should be prepared before entering the classroom (or logging in). This head-to-head comparison concentrated on three crucial components that affect a student's experience. We'll also examine the advantages of "mixed learning" in more detail.
The project encourages Macomb Community College to increase the number of classes it provides to students, both in the physical classrooms and online. College is a time for self-discovery, and there is no better way to figure out one's capabilities and areas of interest than by enrolling in a wide array of subjects during your time there. Macomb analyses data on student learning to pinpoint areas that could benefit from altered rules and procedures. In order to improve the college's Academic Mobility Policy, data on student success is used. This policy establishes a procedure for ensuring that students are enrolled in the proper classes. The set course prerequisites must be met by all students enrolling in English composition, mathematics, reading, and English for Academic Purposes (EAPP) courses. The college has a "mobility period" in place to make sure that students are adequately positioned for success in these foundational courses. Math and English are the subjects where mobility happens the most frequently. As a student, I have participated in a diverse range of classes, and I never stop being astonished by the extent to which the topics overlap.
The Center for Teaching and Learning used the assessment results to provide additional opportunities and resources to support faculty initiatives to integrate communication-based teaching methods into their lessons. On the Macomb Community College Portal, a page titled "Using Assessment Results" was made with resources highlighting communication strategies faculty members can use. Workshops highlighting methods for assisting students in becoming successful researchers, thinkers, and writers in the disciplines were available as professional development opportunities. A book discussion on John C. Bean's book Engaging Ideas - The Professor's Guide to Integrating Writing, Critical-Thinking, and Active Learning in the Classroom was also provided by the Center for Teaching and Learning (2011).

A Brief Introduction to the Use of Technology in Education
http://www.youtube.com/watch?v=rMazGEAiZ9c
Introduction
Can teachers be effective if they choose not to use technology in their classrooms? Unfortunately, there is little agreement among educators on this basic question. In this chapter, we will explore issues associated with teaching and learning in
order to understand when, how, and why technology has the potential to enhance teach-
ing, learning, and performance. Specifically, our goal is to understand whether or not the
decision to use technology in the classroom is up to the individual teacher or if there are
some larger social obligations that require teachers to support technology use by diverse
students in ways that foster meaningful and deep learning.
In other courses you may have been introduced to various theories of learning. Here we
will briefly explore selected learning theories in order to understand their implications for
our personal beliefs concerning how learning occurs, as research has demonstrated that a
teacherâs theoretical framework has considerable implications for the way they adopt and
use technology in the classroom (or not!).
The final sections in this chapter will bridge theory, research, and practice by introducing
you to a model of the technology integration process. While many technology specialists
find all aspects of technology integration exciting, we must not lose sight of the goal for
using technology in the classroom: to enhance student learning. Therefore, youâll be given
a roadmap to the process of integrating technology into the curriculum and learn practical
strategies, resources, and tools that will facilitate this process.

Word Problems are designed to help students to learn the application of mathematical concepts, algebraic identities and formulae in the real world. Variables are assigned the values of âreal-worldâ entities and a logical approach in solving them is established. They help the students to bridge the gap between theoretical knowledge and the real world application of it by giving them hypothetical situations about the same. Probability is a measure or estimation of how likely it is that a particular event will happen. Probability concepts need to be properly understood before attempting to solve any problem related to it. In view of this a survey was conducted. Students from various schools and coaching classes were approached for the same. The study shows that majority of the students experience difficulties in identifying and understanding what exactly the word problem signifies and what approach it demands. Also, the process of learning Probability needs to be specialized given the different understanding levels of each and every student in contrast to the generalized education techniques that are being used in traditional classrooms. Keeping in mind these issues, Word Problem Solver for Probability is implemented, which caters to the learning needs of each and every student individually by providing a step-by-step solution to all problems from the Probability domain.

issues central to
tutoring systems:
the
( 1)
representing domain knowledge, (2) representing instructional
knowledge, (3) modeling student learning, and (4) developing user-
friendly interfaces. The focus of domain learning tasks includes
accounting basics, often covered in the first few chapters of an
accounting principles course.
Introduction
Educators have long sought methods of helping students learn
more effectively and efficiently, in and out of the classroom .
students often seek the help of student tutors. Tutors interact
with the students on a one-to-one basis, explaining basic concepts,
showing students how to solve problems, watching and correcting
students as they solve probLems, and evaluating progress. Research
by educational psychologists indicates that private tutoring, both
student and computer, is even more effective than conventional
classroom instruction in which a student listens to lectures, reads
tests and solves homework problems. [Delaney, 1985) An example is
the LISP tutor at Carnegie Mellon University.
Field studies at Carnegie Mellon University, showed LISP tutor
4. helped college students learn programming faster and more
effectively than other methods. In one comparison, students were
tutored by graduate and undergraduate Carnegie Mellon students with
c;:onsiderable experience in both LISP and tutoring â˘. Another. group of
students read the instructional material and solved the same
sequence of problems on their own, with help from a teacher only
when they were stuck. John Anderson noted that "the basic finding
was that the human tutor is best, the computer is not that far
behind, and the traditional on-your-own practice conditions were
much worse." The advantages of private tutoring by human or
computer, relative to the on-your-own condition, increased with t.he
difficulty of the material. The student subjects took an average of
11.4 hours with the human tutors, 15 hours with the computer tutor,
and 26.5 hours with the on-your-own condition. Students in
traditional classroom settings indicated that they took over 40
hours to cover the material. In another study, students who had
used the LISP tutor did 43 percent better on a final examination-
than those who had conventional instruction. [Delaney, 1985]
Some students struggle to learn accounting. A course in
accounting principles is required in most business schools.
Unfortunately, many students have painful memories of learning
accounting. Too often in the fundamental courses, classes are large
and sufficient tutors are unavailable. It could be effective to
leverage individualized instruction, even augmenting conventional
classroom instruction with intelligent computer-aided instruction
3
5. {ICAI). Creating an intelligent computer requires knowledge that
human tutors must have, including domain problem-solving knowledge,
instructional techniques, and recognition of difficulties a typical
student may encounter. Furthermore, a good user-machine interface
is important.
To effectively observe student progress, discover errors and
offer instruction, a tutor must be able to solve the problems a
student is working on in a manner similar to how an ideal student
would solve problems. This "ideal model" represents the accounting
_knowledge we want the student to acquire. The accounting tutor
follows along as the student solves the problem, symbol by symbol,
trying to figure out what correct or faulty rule would have led to
that input. If it appears that the student is solving the problem
correctly, the tutor only observes and offers encouragement, but if
an error is identified, the tutor may decide to interrupt with
appropriate remedial instruction. Concurrently, the computer is
building an internal model of the student's progress, skills and
difficulties, and how the student prefers to learn. The Accounting
Tutor can thus tailor it's instructions for that particular
student.
Finally, the student is provided with a user-friendly windows
environment, with tools which facilitates accounting problem-
solving. The student has considerable control over the environment,
selecting the degree of computer-aided instruction, amount of help
4
6. to be provided, and what objects will be seen and how they will be
arranged on the screen. In addition, to do this in accounting
requires a workspace similar to accounting workpapers or a
computerized accounting package.
Additional Motivation
More than just building another potentially useful program,
Anderson (1984) noted that building an intelligent tutoring system
is a valuable research tool for the study of mental processes that
are involved in learning. Thus, modelling the student and
investigating tutorial strategies provides insights into
interesting psychological questions as well. Some of these
questions are: How can an individual student be helped to learn
effectively and efficiently? What exactly is 'learning'? What
styles of teaching interactions are most effective and when? ICAI
is important to education because it tries to answer these
questions. (Self, 1988) It has also been argued that the
intelligent models may be considered as theories which can be
tested. (Meservy et. al., 1985)
Background
Many educational researchers consider computers to be the most
important technological development for education since the
invention of the printing press or writing itself. They believe
5
7. that computers will one day transform education, leaving their mark
on education as writing and books have done. Even though computer-
aided instruction (CAI) has been used for many years, results at
the college level have been mixed, although generally moderately
positive, reducing instructional time while increasing learning
effectiveness. [Kulik, 1990]

The following explains how th~ rest of the paper is organized.
The paper first describes the various components of the Accounting
Tutor system and how they interact. The paper then examines some of
the strategies that were used to address various issues and
problems encountered. A classroom experiment is then conducted
along with other tests examining various aspects of the validity of
the model. Results of study are reported, and conclusions,
including future research, are suggested.
The Model
The model for the Accounting Tutor is analogous to several
experts sitting around a blackboard and computer terminal in a
small room. As they watch the input on the computer screen from a
student solving problems, the experts write various notes on the
6
8. blackboard as they also solve the problem. These notes include not
only correct solutions, but also problems and/ or succes.ses the
student seems to be having, the students individualized learning
approach, remedial and expansive instructional material, tailored
learning strategies, and additional accounting problems for the
student to work. Deciding as a group how they can best help the
student, they then place the appropriate messages on the computer.
At times, these messages may be simple positive or negative
feedback. At other times, the messages may include more detailed
definitions, rules, or hints. The system may decide to restart the
problem and demonstrate the correct solution, and then provide the
student with additional problems to solve. The system will also
respond to a student's request for various levels of help.
The experts, described below, consist of a Student Modeler, a
Problem Solver, a Diagnoser, and a Tutor. Modeling the system as a
number of individual experts allows departmentalization of
knowledge, decoupling a number of interactions leading to
complexity. It also allows easier modification or addition of
experts in the system. The first expert in the system models the
student, keeping track of the students knowledge, problems, and
learning strategies.
The Student Modeler
Intelligent tutoring systems generally include some simulation
7
9. of current student knowledge. A student model represents the
knowledge a student has learned and the difficulties he has had in
learning. Student models differ in whether they explicitly model
trhe individual learning history or not. Shank considers knowledge
to be non-formal and primarily case-based, which may be generalized
upon demand. Building on this foundation, the student model will be
episodic in nature, incorporating the case-exercises the student
has encountered, previous instructions and helps received, and
problems identified. This differs from more static models (e.g.
differential learner models). A case-based student model allows the
tutor system to offer examples based on reminders of earli_
er
problems the student has successfully solved. Generalization of
these episodes may also reflect the student's learning process.
[Weber et. al., 1988)
Some student models are based only on the work accomplished in
a given session, on the basis of rules that detect bugs and¡
corrects solutions. (Anderson and Reiser, 1985) Other models
summarize what concepts were learned and how effectively they were
applied. (Burton and Brown, 1982) our student model will
incorporate both rules and a case-based model proposed by Weber et.
al. (1988) in which knowledge is considered non-formal and dynamic.
Expert knowledge is sometimes represented as a formal collection of
rules. In contrast, knowledge can also be represented as a set of
examples or cases based on previous experience from which an expert
generalizes to construct rules as needed. Keeping track of both the
8
10. student's history and current skills will allow a wide range of
tutorial responses built on both generalization and specific
behavior. It will also allow the tutor to remind the stuno,,..4- nf
specific examples, which the student has already completed, in
order to assist the student in the generalizatjon nrocecc _
Summarization for research and grading purposes is also possible.
The Problem Solver
The problem solver solves the accounting problem at the same
time the student is solving the problem on the screen. Initially,
the problem solver may use pre-solved (template) solutions to the
problems, however, additional. knowledge about the accounting domain
and accounting rules will continue to be added, so that the problem
solver can examine most common accounting problems, applying the
appropriate rules to solve the problem. Adding such knowledge will
greatly expand the versatility of the Accounting Tutor.
The Diagnoser
Diagnosis plays a distinctive role in instructional programs.
The diagnoser works hand-in-hand with the student model and problem
solver. The diagnoser watches the student's actions, looking for
discrepancies from the ideal solutions produced by the problem
solver. Potential problems and difficulties are recognized. It then
tracks these discrepancies back to faults in the student's presumed
9
11. world model or inference procedure. The diagnoser interprets the
performance of the student, making judgements relating to the
student's strengths and we'aknesses. The diagnoser then tries to
'repair' the student by passing this information on to the tutor.
In cognitive systems, the process of causally tracking backwards
from the discrepant reasoning behavior to the hidden faults is
called diagnostic modelling. (Clancey, 1986] The diagnoser also is
programmed to recognize various student learning strategies. Long-
term results are stored with the student model.
The T'l;1tor
Results of performance interpretation are transferred to the
tutor if need is inferred from student's performance, otherwise
only system state and user models are updated. The recognized needs
and resulting functions of the tutor are similar to those found in
EUROHELP tutor. [see Breuker, 1988] When the student exhibits
specific needs, the following tutor functions are available:
Need Function
Lack of basic concepts
Lack of potentially
relevant concepts
Lack of Information of
correct action
Error/misconception
Initial instruction
Expansion
state feedback
Remedial
12. The initial instruction functions set forth the basic concepts
and principles, and may be presented by the tutor, or requested by
the user. Expansion is aimed at instructing new concepts that may
augment the student's understanding, usually through additional
problem solving and comment. Besides the basic practice of
learning-by-doing, expansion helps students refine their expertise.
F.xpansion differs from the initial instruction bv oroceedina in
small steps, with an acquired uncter~~anding of what the student
knows. State feedback provides information to the student about
where they are in the problem and suggests goals of what needs to
be done next. As with other tutorial systems, identified errors and
misconceptions result in remedial learning action.
The Structure of Goals in Accounting Tutor
The tutor's structure consists of three layers: didactic
(educational} goals, strategic decisions, and tactical methods.
[Woolf and McDonald, 1984] These three layers provide control over
tutoriai actions taken. Although help requested is based on local
problems and apparently simple questions, what will be taught is
not only dependent on current needs and skills, but also on long-
term didactic goals. These goals lead the computer to decide
whether simple, straight-forward advice will be given and/or new
concepts will be taught. (Breuker, 1988] The didactic goals are
represented in the form of semantic nets. The semantic net includes
both (1) the order in which concepts are to be learned and (2)
11
13. reference to the expansion of knowledge required.
At the strategic level, decisions include whether or not to
interrupt the user, and what sequence of tactics should be applied.
This decision is not only dependent on current performance, but
interruptions also ma be set b the user. For example, one user
may want to be interrupted only for the most serious errors, while
~ -¡- -
another may desire feedback on each step taken. A user may always
override the advice, for instance when they already realize what
they did wrong. Interrupt levels represent a style of tutoring,
which along with levels of specificity can be set by the user.
Tactics are represented by structural text frames, where slots
may be inserted with the value of objects based on the current
problem. This is similar to the definition of tactics used in
Geometry and LISP tutors by Anderson et. al. [1985]. To the user,
tactics appear to be similar to context-sensitive help windows.
The Accounting Platform
The accounting platform provides much of the computer screen
medium on which the student will solve numerous accounting
problems. The platform contains not only what is normally
considered a full accounting system with the required financial
statements, ledgers, and journals, but also allows a considerable
amount of input flexibility and user-friendly interfaces. The
12
14. platform allows for small end-of-chapter textbook problems or large
case studies, with the ability to save intermediate results.
Besides automatically calculating all math and ratios as needed,
the system provides the flexibility of pointing to amounts in the
problem case window and automatically picking up these amounts with
a mouse, dragging, and then dropping them onto the appropriate
journal, ledger, or financial statement. The updated results in all
related financial accounts are immediate, allowing the student to
see the flow-through to the financial statements. If appropriate
permission is set, amounts may be dropped directly on the financial
statement line-items (accounts), updating concurrently the journals
and ledgers. This is possible ¡ because financial statements,
journals, and ledgers only represent views of the underlying data
entries. The platform is implemented with an object-oriented
design, allowing considerable domain knowledge to be stored and
inherited in the underlying classes. It is hoped that such a
platform will facilitate the learning process by eliminating some
of the mundane tasks often associated with bookkeeping.
The User-Interface
The user-friendly interface is achieved by using a windows
environment, with numerous buttons for setting up the student's own
personalized desktop on screen. A large variety of windows can
brought-up, sized, and placed on the screen where the student
desires. Most of these windows also contain attributes that can be
13
15. set, sucll as color. In addition to various accounting platform
windows, other windows available include the problem, current
problem goals and status, student work summaries, various help and
hint windows, tutorial windows, stude.n.t no+-= and scratchpad
windows. Other buttons suggest to the tutor the amount of help the
student desires.

Future Plans
Future plans include the investigation of "failure-driven
learning." Erroneous strategies, missing concepts, and faulty
14
16. generalizations result in failures which guide the reorganization
of structures in episodic memory. Sometimes using analogies of the
student's own learning history should be offered by the tutor in
order to help the student learn from those mistakes., [Weber et.
al. , 1988]
