you will need for this problem set.
Problem 1: The Single Index Model and APT [21 points]
See the worksheet named “Problem #1” for returns data that will help you complete this problem.
A. [6 points] Compute the excess return for two funds (BOTZ and VIG) and two stocks (MMM
and QCOM) and for the market by subtracting the risk-free return. Note that all returns provided
are monthly. Use those excess returns to estimate the market model (single index model) for each
of the 4 investments. Present the alpha, beta, and residual variance for each of the 4 investments.
B. [3 points] Using your estimate from part A, estimate the alpha and beta of the following
portfolio: 20% BOTZ, 40% VIG, 20% QCOM, and 20% MMM.
C. [4 points] Is the residual variance greater for the individual stocks (MMM, QCOM) or for the
funds (BOTZ and VIG)? Why do you think that is the case?
D. [4 points] Plot the 4 investments on the security market line.
E. [4 points] Estimate the Fama-French 3-factor model and report the coefficients, t-statistics,
and the R2.
Problem 2: Comparing performance [7 points]
Two investment professionals are comparing their return performance. The first professional managed
portfolios with an average return of 15% and the second professional managed portfolios with a 12% rate
of return. The beta of the first portfolio was 1.2 while the beta of the second was 1.0. The risk-free rate
of return was 2% and the expected market return is 10%.
A. [5 points] Which manager was a better selector of individual stocks, and why?
B. [2 points] Plot both of the portfolios on the security market line.
Problem 3: Closed End Funds [10 points]
See the worksheet named “Problem #3” for the prices and NAV of a recently IPO-ed closed end fund,
Angel Oak Financial Strats Income (FINS).
A. [5 points] For each day, compute the premium (discount) of the price to the NAV. Compute the
B. [3 points] Plot the premium (discount) through time on a graph.
C. [2 points] Explain if this fund exhibits the same premium(discount) pattern around its IPO and
post-IPO period as the example we discussed in class.
Problem 4: Mutual Fund Returns [15 points]
You are considering investing in a mutual fund’s A share class that has a 2% sales charge (front-end
load) and annual expense ratio of 1.0%. Alternatively, you might invest in that fund’s C shares that
have no load and an annual expense ratio of 1.15%. Assume the fund’s assets return 10% annually.
a. [3 points] For a 2-year holding period, which share class will you prefer?
b. [3 points] For a 50-year holding period, which share class will you prefer?
c. [5 points] After how many years will the two mutual fund share classes result in the same
future wealth amounts?
d. [2 points] How does your answer to part c. change is the fund’s assets return 14% per
year?
e. [2 points] What accounts for the greater expenses of the C-shares, compared to the Ashares?

INTRODUCTION
In the last decade online teaching and learning
has become the norm in many institutions of higher
learning. Numerous institutions are offering online
courses both nationally and internationally. The
Online Consortium tracks online education in the
Unites States and releases an annual report entitled
The Online Report Card. The most recently
released report (Allen & Seaman, 2016) showed
there were more than 5.8 million students in the
United States enrolled in one or more online courses
in the fall of 2014. This constitutes 28.4% of all
student enrollment. The report further stated that
believe online learning is a critical component of
their long-term strategy. It also stated that 77.14%

this mismatch is critical to realizing the full
potential of the online classes that the students are
increasingly expecting.
Data were collected from students in an online
MBA program (Kim, Liu, & Bonk, 2005) through
semistructured, one-on-one interviews, surveys,
and in-person focus group interviews. It was determined that over 70% of those surveyed described

and integrating these eight facets of effective online
teaching was a possible reason for the hesitancy
within the ranks of the faculty to embrace online
teaching (Allen & Seaman, 2016).

Among them are MyLab by Pearson, MindTap

these tools can bridge the gap between student
expectations and the hesitancy of faculty to meet
the core needs of students.

LITERATURE REVIEW
In recent years, blended teaching and learning,
which includes online versus face-to-face, has
grown immensely; yet, the literature is not as
abundant as one would expect. Not only has
learning been under scrutiny, but some studies

professor-student interaction, and a host of other
facets of teaching and learning. Smith and Bryant

tips for guiding online discussions. Dotterweich
and Rochelle (2012) also lamented the paucity
of research examining student characteristics
and factors leading to successful outcomes.
They studied three modes of delivery (online,

They found no difference in the performance

In addition, they found that participation in

Hegeman (2015) examined whether student
performance in an online College Algebra course
could be improved if instructor-generated video
lectures were used instead of publisher-generated
educational resources. The study involved a College
Algebra course that used all the publisher-generated
educational resources and another course in which
students completed instructor-generated guided
note-taking sheets while watching instructorgenerated video lectures with publisher-generated
learning aids available as supplemental resources.
The results of this study showed that strategically
placing instructor-generated content improved

of the videoconferencing software Blackboard

by Tonsmann (2014) and found to be an effective
method for educating students at a distance.
A multiple regression analysis used a dataset
that included over 5,000 courses taught by over

revealed a statistical difference among course
formats that amounted to a negligible difference
of less than 0.07 GPA points on a four-point scale.
The authors further found an interaction between
course type and student GPA, indicating that
students with higher GPAs performed even better
in online courses. Alternatively, struggling students
performed worse when taking courses in an online
format compared to a face-to-face format.

METHODOLOGY
The opportunities thrown open by the
increasing popularity of online courses comes

challenges such as mastering software platforms
for content delivery, interacting with students,
online content delivery, participation, assessment,
learning style, time management, and motivation.
There are technical solutions for many of these
challenge and publishers offer learning platforms
for popular textbooks.
Quantitative courses present tough challenges
when they are offered online. Mastering

Publisher online platforms have modules that
provide the opportunity for students to practice
DQGPDVWHUFRQFHSWVEHIRUHWDNLQJWHVWV3HDUVRQ¶V
MyOmLab platform includes several tools that can
be used for practice and learning concepts as well
as assessments. They include Practice, QuizMe,
Homework, Quiz, and Test.
As students work on each section of the
chapters of the textbook and achieve a minimum
score in a combination of assessment tools set by
the instructor, the students earn a Mastery Point.
In this study, three tools were used: Practice,
QuizMe, and Chapter tests. Students can learn
concepts and problem-solving skills by using the
practice tool, which allows students to seek help
from a variety of sources including reaching out
to the instructor. The QuizMe tool allows students
to self-test at the level of mastery achieved by
using the practice tool. In this study, we set the
minimum threshold of 80% in the QuizMe for
students to earn the Mastery Points associated
with the section. If a student failed to achieve
the minimum score, she or he could go back to
Practice and then retake the QuizMe until earning
the Mastery point. In as much as students can
seek help while using Practice and repeat QuizMe
unlimited times, Mastery Points earned had half

content, but students could not receive any help

However, the time recorded by the MyOMLab
system is the duration of time the students were

Mastery Scores. It may have included idle time
when students took a break or failed to log off after
completing the task. Therefore, it was very likely
that the time recorded by the system was not the
accurate measure of time students actually spent

is the uncertainty with respect to which strategies

ABSTRACT
Offering many advantages to adult learners, e-Learning is now being recognized – and preferred – by more and more
people, resulting in an increased number of distance learners in recent years. Numerous research studies focus on learner
preferences for online learning, with most converging around the individual characteristics and differences, if not the
features of the technology and pedagogy used. For Turkey, the situation is also similar, with the number of adult learners
who prefer online learning increasing each year due to several reasons. The result of this is an increase in the number of
online programs offered by many universities. Hence, this research study has been conducted to reveal the prevailing
factors causing learners to choose online learning. Through this qualitative research regarding online learners in a state
university, it is found that having a full time job, accessibility and flexibility, individual responsibility, effective time
management, physical distance, institutional prestige, disability are the common factors for under graduate and graduate
learners in their preference for online learning. Awareness of these factors can support the stakeholders while designing
e-Learning from both technological and pedagogical points of view.
KEYWORDS
Online learning, preferences, expectations
1. INTRODUCTION
Offering many advantages to adult learners, e-Learning is now being recognized – and preferred – by more
and more people, resulting in an increased number of distance learners in recent years. Emphasizing that
distance education has a bright and promising future, Zawacki-Richter and Naidu (2016) stress that, ³In fact,
there has never been a better time to be in the field of open, flexible, distance and online education than
QRZ!´ (p. 20).
The commonly discussed factors that make online learning attractive for adults are: independence from
time and place; accessibility, and; economic reasons. With the MOOC movement, extremely high quality
online courses are now being delivered to learners by many well-known universities. Moreover, many
universities are either providing online programs or courses as a support to traditional instruction, in the form
of blended learning, flipped classes, etc. Indeed, there are almost no universities left who GRQ¶W benefit from
these advantages of technology usage and its support in teaching-learning processes.
A variety of reasons might account for these learning preferences. da÷OaU aQG TXUJXW (2014) attempted to
identify the effective factors for the e-learning preferences of university students; they concluded that,
³EIILcLHQW XVaJH RI WLPH aQG UHGXcHG HGXcaWLRQaO H[SHQVHV ZHUH IRXQG WR bH RQ WRS RI WKH OLVW aV WKH PRVW
valued advantages of e-OHaUQLQJ´ (S. 46). Moreover, having responsibilities, a full-time job and no access to a
nearby university may also cause learners to prefer online learning.
APRQJ WKH IacWRUV WKaW aIIHcW OHaUQHUV¶ aWWLWXGHV WRZaUG H-learning, a positive attitude toward technology,
ease of access and use of internet, computer literacy, perceived usefulness, self-efficacy, motivation,
patience, self-discipline, and self-regulation seem to be widespread and the most commonly reported (Liaw,
Huang & Chen, 2007; Nogueira & Machado, 2008; Sun, Tsai, Finger, Chen & Yeh, 2008; Bertea, 2009). On
the other hand, Lim and Morris (2009) examined the influence of instructional and learner variables on
learning outcomes for a blended instruction course and VWaWHG WKaW ³« age, prior experiences with distance
learning opportunities, preference in delivery format, and average study time are those learner antecedents
differentiating learning outcomes among groups of college students´ (S. 282).

RHJaUGOHVV RI OHaUQHUV¶ aWWLWXGHV WRZaUG H-learning, instructional design plays an all important role during
an efficient online learning process. From the literature, it can be seen that the most common instructional
design models ± such as ADDIE, ASSURE, Dick & Carrey, Smith & Ragan – start with the analysis step.
This step can be broken down into analysis of the learner, content, media and aim. Nevertheless, the question
is: after analysis, are designers really reflecting the possible applications in their instructional design process?
In many online learning programs learner analysis was carried out cROOHcWLQJ OHaUQHUV¶ JHQHUaO
demographic data. Even if the target group of learners have similar academic backgrounds, these learners
tend to have very different individual properties (Navarro & Shoemaker, 2000; Conrad & Donaldson, 2010),
expectations (Dabbagh, 2007; Moskal & Dziuban, 2001) and motivation (Keller & Suzuki, 2004; Kearsley,
2002) levels. Therefore, after enrollment, institutions or practitioners should conduct a deep learner analysis;
this also influences the quality of instructional design in a holistic way. Thus, institutions can aim to decrease
the drop-out rates (Park & Choi, 2009; Chyung, 2001), increase the attendance (Yudko, Hirokawa & Chi,
2008; Rovai, 2003) and, in general terms, maintain a more efficient learning process.
Numerous research studies have focused on learner preferences for online learning, with most converging
around the individual characteristics and differences, if not the features of the technology and pedagogy used.
A similar situation is seen in Turkey, with the number of adult learners who prefer online learning increasing
each year due to several reasons. The result of this is an increase in the number of online programs offered by
many universities. For this reason, the current research study has been conducted to reveal the prevailing
factors causing learners to choose online learning. Thus, this research seeks answers to the following research
questions:
1. What are the factors that affect VWXGHQWV¶ SUHIHUHQcHV IRU RQOLQH OHaUQLQJ?
2. Are there any differences between program types in terms of student preferences?
2. METHODOLOGY
2.1 Research Design
This research is designed as a qualitative study. Participants were requested to answer two online open-ended
questions at the beginning of fall semester, and asked underlying reasons for their choice of online learning
method, and their expectations about online learning.
2.2 Participants
Participants of this study were the online learners of a state university who were enrolled in various
e-learning programs. These programs were composed of six undergraduate degree and four graduate degree
programs. Most of the online learners were females (55%), married (59%) and aged 18-25 (41%). Detailed
demographics for the participants are presented in Table 1.

2.3 Data Analysis
After checking all of the responses, it was found that 944 participants from undergraduate level and 178
participants from graduate level were suitable for data analysis. The collected data was coded separately by
the researchers. None of the qualitative data analysis software has been used, because of not missing any
statement. In this research, coding was conducted according to WKH SaUWLcLSaQWV¶ cRPPHQWV, aQG the codes and
themes were generated by the researchers.
A member checking validation strategy was used in this research for validity (Creswell, 2007), and also
an intercoder agreement strategy was used for reliability. Two different coders – apart from the researchers –
analyzed the codes and themes for a second time. For this dataset, CRKHQ¶V KaSSa cRHIILcLHQW ZaV caOcXOaWHG
and found to be 0.90, which is within the range of acceptability (Krippendorff, 2004; Landis & Koch, 1977).
In terms of member checking, researchers called (via phone) 10 randomly selected participants, and talked
about their online learning experiences and reasons for their preferences. During meetings they emphasized
the similar preferences for online learning.
3. RESULTS
After the qualitative analysis, researchers identified 12 themes within the undergraduate students¶ data. The
themes for undergraduate level are presented in Table 2.

According to the data analysis, having a full time job is the most significant theme regarding the VWXGHQW¶V
reasons for their preferences. They stated that the desire to run their work life and education together, and
also the high tempo of work life forcing them to choose distance education programs. The majority of
students were between 26 and 41 years of age, this data also proves that these students can be active workers
in life. The students stated their situation, as is seen in the example below:
³I am Zorking, and m\ age is 35. Still, I can complete m\ education into m\ area of
interest, and have a diploma via distance education.´ [P-722]. ³I am working, and I don¶t
have any time for traditional learning programs. I choose this program, because it was the
only way for me to learn.´ [P-715].
132
The other emerging theme was that of accessibility and flexibility. The nature of distance education is that
it is independent from location and time, which are also important criteria LQ WHUPV RI VWXGHQWV¶ SUHIHUHQcHV.
³Distance education gives me a large choice of time and location, so I don¶t need to be at
an exact place and time. Also, I can continue to my other diploma program which I
enrolled in before.´ [P-23]. ³It¶s ver\ eas\ to access and the practical, discretionary
participation feature to the synchronized sessions is very important for me. Also, the
opportunity of listening to sessions from records, and from different lecturers makes me
choose distance education.´ [P-92]. ³I choose distance education, because I can stud\
whenever I want. I can listen to session recordings and there isn¶t an obligation about
attending s\nchroni]ed sessions.´ [P-373].
Another characteristic of distance education students is that, generally, WKH\ cRXOGQ¶W cRPSOHWH, or even
start, their education because of their individual responsibilities. This situation can be seen from the codes
and themes emerging from the data. Most of the students stated that they have to take care of their family and
children, or even a relative such as a nephew, or their grandparents.
³I had to choose distance education, because there is no one to take care of m\ nepheZ.´
[P-53]. ³I am married, and have 3 kids. I really appreciate that this opportunity is provided
to us.´ [P-491]. ³I choose distance education because I am married and have 2 kids. M\
kids are going to elementar\ school, so the\ need me at home.´ [P-592].
According to the analysis, a point will soon be reached where the large majority of students are likely to
enroll on a distance education program, as this enables them to manage their time very efficiently, and also
handle with family and work responsibilities as well.
Financial problems and being in a prison are addressed in the individual difficulties theme. Students
stated that living far away from the university can cause a high level of transportation, accommodation and
educational expenses for them. As a solution to such potential financial issues, they prefer distance education.
In addition to this, students who have been in prison stated that continuing their education through distance
education is a huge disadvantage for them even if in their circumstances.
After analyzing the VWXGHQWV¶ GaWa, UHVHaUcKHUV IRXQG WKaW students consider distance education as
systematic, coordinated, repeatable, offering good interaction with teachers, enabling participation from
home, creating the chance for individual work, containing visual-audio presentation techniques, and offering
virtual classroom activities. All of these specifications are considered in the features of the learning
environment theme. Physical distance, having a second degree, institutional prestige, aging and disability
themes also emerged from the qualitative data. Students stated their reasons as follows:
³I have a physical disability; as a result of this, transportation is a problem for me. So, I
choose distance education´ [P-522]. ³I am a congenitall\ hearing disabled person; with
distance education I can listen to m\ courses over and over´ [P-840]. ³The cit\ I lived in
doesn¶t have m\ program¶s formal version´ [P-121]. ³I am travelling a lot because of m\
job, so I have to be in different cities most of the time´ [P-327]. ³The appealing factor for
me Zas the universit\¶s prestige. Having a diploma from such big university is very
important for me´ [P-878]. ³I lost the chance to go to university years ago. I believe that
learning should be from birth to death. Now I am at the age of 35, and continuing my
education at this age makes me happy´ [P-911].
133
After analyzing the JUaGXaWH VWXGHQWV¶ GaWa, 8 WKHPHV arose. Compared with the uQGHU JUaGXaWH VWXGHQWV¶
themes, it was found that there were 7 common themes, and only 1 of these was different from the others.
These themes are presented in Table 3.
Table 3. Themes for graduate students

Having a full time job 90 44,12
Effective time management 42 20,59

Physical distance 13 6,37
Individual responsibility 7 3,43
Institutional prestige 1 0,49
Disability 1 0,49
Total 204 100
The lifelong learning theme consisted of students¶ wishes about increasing their academic knowledge,
and providing professional development. Within the context of these aims, they stated that the reasons for
their preferences as:
³Distance education provides me with continuing education, and I¶m improving myself
academically as well as in my work life´ [P-13]. ³I believe in lifelong learning, but I am
dealing Zith a high tempo Zork life. I couldn¶t attend a traditional program because of m\
workload, so I choose distance education. Distance education is a very useful system for
busy people like me´ [P-46]. ³I choose distance education because it Zas the most
appropriate method with which I can continue with minimum loss elsewhere. Besides, I
believe that, after completing this program, I Zill be in a better position in m\ Zork life´
[P-53].
When looking over the order of the themes, having a full time job was the most important, as was the case
in the XQGHUJUaGXaWH SURJUaP VWXGHQWV¶ GaWa. Effective time management, and accessibility and flexibility
were the next themes in terms of importance. Also being married, having children, living outside of the city
or country, and being a part of a leading university were the other reasons mentioned.
4. CONCLUSION
The results of this study indicate the importance of distance education, which can provide the equality of
opportunity independent of graduation level. Every person has the right to obtain a quality education,
regardless of whether it is a graduate or undergraduate degree. Sometimes life obstacles can be a barrier in
IURQW RI SHRSOH¶V choices. In this study, the researchers aimed that identify WKH GLIIHUHQcHV bHWZHHQ VWXGHQWV¶
reasons for their preferences for distance learning. It was found that, generally, these reasons were parallel
between these two degrees, but also there were some differences regarding certain points.
The common themes for both of the groups were having a full time job, accessibility and flexibility,
individual responsibility, effective time management, physical distance, institutional prestige, and disability.
The differences were in terms of preferences at graduate degree level, individual difficulties, features of the
learning environment, academic preference, obtaining a second degree and the aging process. For graduate
students, the predominant difference was the desire for lifelong learning. Actually, these themes tend to
represent the studentV¶ characteristics. Undergraduate degrees are fundamental for finding a job, so this is an
obligation for most students. Because of this, people who have difficulties regarding their budget, health
issues or special conditions prefer distance education to a greater extent. SLPLOaU GLIILcXOWLHV aUHQ¶W RbVHUYHG
at graduate level. Graduate level is not an obligation for a job; it depends much more on intrinsic motivation.

This is why these seven WKHPHV ZHUHQ¶W HYLGHQW LQ WKH data analysis. According to the analysis, people who
enroll on a graduate level program are seeking more professional development.
According to both qualitative and demographic data, those people who can¶W cRPSOHWH RU HYHQ VWaUW WKHLU
education due to family responsibilities are, generally, the female students. Consequently, with distance
education female students are able to find their place in social and work life much more effectively than
before. Social roles and/or cultural expectations can bring about certain disadvantages to females, but it is
shown that distance education can play an important role in overcoming these issues.
Hence, although this research does not add any specific new findings to the field, it was important to
revisit the underlying factors influencing learner preferences, since technology and pedagogy should be
shaped according to these needs. Providing education services to all the people who need them, and also
increasing the quality of education in an accessible way provides numerous benefits to people¶V lives. With
the use of regular tracking systems, educational practitioners can better understand VWXGHQWV¶ UHaVRQV for
preferring distance learning, as well as their expectations. Thus, institutions can provide a more enhanced and
comprehensive service.
