ABSTRACT
This study employed an extended technology acceptance model (TAM)
to predict Internet usage in two developing countries (Chile and United
Arab Emirates (UAE)). In addition to investigating the impacts of
perceived ease of use (PEOU), perceived usefulness (PU), and perceived
Internet content (PIC) on students' usage of the Internet, it
analyzed the direct impacts of external variables such as gender,
educational background, income level, self-reported measure of computer
knowledge, Internet cost, and Internet availability on Internet usage
and their moderating role in the relationship between PEOU, PU, and PIC
and Internet usage. To validate the research model, data was collected
from 169 students from Chile and 194 students from United Arab Emirates
(UAE). The results showed that only PU was a significant predictor of
Internet usage for both Emirates and Chilean samples. Additionally,
while gender significantly impacted Emirates students' usage of
Internet, self-reported knowledge about computers significantly impacted
Chilean students' usage of Internet. Income level was the only
significant moderator for both countries. PU affected usage of the
Internet more positively for students with high income level than it did
for those students with low income. Discussion of practical implications
of the results was included.
INTRODUCTION
Most studies of the Internet have focused primarily on adoption,
e-commerce, and web design (e.g., Kim et al., 2005; Park, et al., 2004;
Stanfield and Grant 2003; Ranganathan and Grandon 2002; Tan and Teo
1998; Teo and Pian 2004). Little research has been done on student usage
of the Internet (Alshare et al, 2005a). Additionally, the majority of
studies on Internet usage in the last decade have been carried out in
developed countries. There is a need to understand not only why
technology has or has not been adopted but also to comprehend the
impacts of its adoption by developing countries. The Internet has major
impacts upon the ability of developing countries and citizens to be more
effective participants in the emerging global business environment.
The Technology Acceptance Model (TAM), introduced by Davis (1989),
is the most popular model used in Information Systems (IS) literature to
predict the intention or the usage of Information Technology (IT).
According to the citation index of the Institute for Scientific
Information (ISI 2005), by September 2005, there were 631 journal
citations for the original Davis (1989) article. In his model, Davis
introduced perceived ease of use and perceived usefulness as the two
main factors that influence computer usage (e-mail). TAM has been used
in predicting intention or usage of different computer applications
primarily in the region of North America (Lapczynski 2004; Pijpers
2001). TAM was then extended by incorporating additional factors; see
for examples, (Alshare et. al, 2004; Davis et al., 1989; Gefen and
Straub 1997; Venkatesh et al. 2003; Venkatesh and Davis 2000; and Lucas
and Spitler 2000). It is worth mentioning that there were few studies
that tested TAM or extended versions outside the region of North
America, primarily in developed countries (e.g., Al-Gahtani 2001, Huang
et al., 2003; Lai and Wong 2003; Straub et al., 1997). Moreover, fewer
studies applied TAM or extended versions to developing countries (e.g.,
Akour et al. 2006; Elbeltagi et al., 2005; Loch et al., 2003; McCoy et
al. 2005; Parboteeah et al., 2005; Rose and Straub, 1998; Zakour 2004).
In this study, we extended the research that was conducted by
Alshare et. al (2005a) by including more external variables such as
Internet cost and Internet availability. Additionally, we tested a
modified TAM model outside the region of North American in two
developing countries, Chile and the United Arab Emirates (UAE). These
two countries represent two emerging economies (The World
Competitiveness Yearbook, 2002).
LITERATURE REVIEW OF CONSTRUCTS AND HYPOTHESES
Perceived Ease of Use (PEOU) and Perceived Usefulness (PU)
According to TAM, perceived ease of use refers to the extent to
which a person feels that using a particular technology would be free of
effort. On the other hand, perceived usefulness refers to the extent to
which a person believes that using a particular technology would enhance
his/her productivity and effectiveness (Davis 1989). TAM has been
utilized in many studies and found that PEOU and PU were significantly
related to computer usage (Adams 2002; Igbaria et al., 1997, Mccloskey
(2003-2004); Seyal et. al. 2002; Venkatesh and Davis 2000). Seyal et al.
(2002) developed a model to test whether PU, PEOU, and other variables
determine Internet usage among college academics. They found that PU and
PEOU were significant predictors of technology usage. In this study, we
focused on PU and PEOU to explore their direct impact on Internet use.
Thus, we developed the following hypotheses for testing:
H1: Perceived ease of use (PEOU) has a significant impact on
Internet usage.
H2: Perceived usefulness (PU) has a significant impact on Internet
usage.
Perceptions of Internet Content (PIC)
Many studies have focused on factors that make web sites more
attractive to users (Liu and Arnett 2000; Park, et al., 2004;
Ranganathan and Ganaphaty 2002; Ranganathan and Grandon 2002). Internet
content was found to be a major factor that influenced user usage of the
Internet (Huizingh 2000; Torkzadeh and Dhillon 2002; Palmer 2002).
However, Alshare et al (2005a) investigated students' usage of the
Internet in the USA, and they found that PEOU and PU, but not PIC had
significant influence on Internet usage. Since this study focused on
students in Chile and UAE who represent two different cultural settings
(Hofstede 1997), it was natural to think that some people perceived
Internet content as a threat to their values and culture and avoided its
usage, while others had a positive perception toward it and would
continue or start to use it (Alshare 2005b). Thus, we proposed the
following research hypothesis:
H3: Perception of Internet content (PIC) has a significant impact
on Internet usage.
The Impact External Variables
Many studies have explored the effect of external variables on the
relationship between PEOU, PU, and technology usage (Alshare et al.,
2005a; Alshare et al., 2004; Venkatesh et al., 2003; Venkatesh and
Morris 2000). For example, Alshare et al. (2005a) explored the direct
effect of external variables (gender, income level, educational
background, computer users' classification, and self-reported
measures of computer knowledge) on Internet usage and their moderating
effect on the relationship between PEOU, PU, and PIC and Internet usage.
They found that gender was the only significant moderator (PEOU affected
usage of the Internet more strongly for female students than it did for
male students). However, they found that classification of computer
users and self-reported knowledge about computers were significant
predictors of Internet usage. Venkatesh and Morris (2000) explored the
moderation effect of gender on the relationship between PEOU, PU, and
subjective norm with the intention to use a system for data and
information retrieval. They found that male technology usage decisions
were more strongly influenced by their perceptions of usefulness, while
females were more strongly influenced by perceptions of ease of use. It
was also reasonable to assume that the cost and the availability of the
Internet would influence students' usage of the Internet. For
example, Alshare et al., (2003) found that there was a significant
relationship between Internet cost and its usage. Based on the above
discussion we proposed the following hypotheses:
H4: Gender has a significant impact on Internet usage.
H5: Educational background has a significant impact on Internet
usage.
H6: Income level has a significant impact on Internet usage.
H7: Self-reported knowledge about computers has a significant
impact on Internet usage.
H8: Internet cost has a significant impact on Internet usage.
H9: Internet availability has a significant impact on Internet
usage.
In this study, we followed the aforementioned research and proposed
that gender, educational background, income level, self-reported measure
of computer knowledge, Internet cost, and availability can be considered
as moderating variables in the relationship between PEOU, PU, and PIC
and Internet usage. Thus, we proposed the following set of hypotheses:
H10a: The impact of perceived ease of use on Internet usage depends
on gender.
H10b The impact of perceived ease of use on Internet usage depends
on educational background.
H10c: The impact of perceived ease of use on Internet usage depends
on income level.
H10d: The impact of perceived ease of use on Internet usage depends
on self-reported knowledge about computers.
H10e: The impact of perceived ease of use on Internet usage depends
on Internet cost.
H10f: The impact of perceived ease of use on Internet usage depends
on Internet availability.
H11a: The impact of perceived usefulness on Internet usage depends
on gender.
H11b: The impact of perceived usefulness on Internet usage depends
on educational background.
H11c: The impact of perceived usefulness on Internet usage depends
on income level.
H11d: The impact of perceived usefulness on Internet usage depends
on self-reported knowledge about computers.
H11e: The impact of perceived usefulness on Internet usage depends
on Internet cost.
H11f: The impact of perceived usefulness on Internet usage depends
on Internet availability.
H12a: The impact of perceived Internet content on Internet usage
depends on gender.
H12b: The impact of perceived Internet content on Internet usage
depends on educational background.
H12c: The impact of perceived Internet content on Internet usage
depends on income level.
H12d: The impact of perceived Internet content on Internet usage
depends on self-reported knowledge about computers.
H12e: The impact of perceived Internet content on Internet usage
depends on Internet cost.
H12f: The impact of perceived Internet content on Internet usage
depends on Internet availability.
RESEARCH METHOD
The Proposed Model
Based on the previous analysis, we proposed the following
theoretical model.
2[FIGURE 1 OMITTED]
Survey Questionnaire
In addition to asking questions concerning demographic variables
such as gender, age, educational background, and income level, the
questionnaire solicited information about Internet usage, PEOU, PU, and
PIC. Five items were used to measure each of the PEOU and PU constructs
that were taken directly from Davis' (1989) scale and modified to
measure Internet usage. The PIC construct was adopted from Alshare et
al., (2005a). Four items were used to measure the construct PIC. The
survey instrument was developed, reviewed for content as well as
readability, and pilot tested; then, the survey was modified
accordingly. Survey participants responded to statements using a 5-point
Likert scale ranging from strongly disagree to strongly agree. The
Statistical Packages for the Social Services (SPSS) was used to compute frequencies, means, percentage, factor analysis, and reliability
(Cronbach alpha coefficient). The regression procedure was utilized to
test the hypotheses.
Samples and Data Collection
The survey questionnaire was administered to convenient samples of
college students in the UAE and Chile during Fall 2003-Spring 2004. In
Chile and UAE, colleagues of the authors were approached and asked to
distribute the survey to students in their schools. Students completed
the survey during class time; then the surveys were collected by the
instructors and sent back to the USA via postage mail. The questionnaire
was distributed to 300 college students in each country. Since English
is the second spoken language in the UAE and students and instructors
were familiar with it (AMIDEAST 2005), the questionnaire was
administrated in English to the UAE sample. In Chile, however, the
questionnaire was administered in Spanish, since only 2% of Chileans
older than 15 years were fluent in English (Miranda, 2004). Back
translation procedure (Brislin, 1986) was used to ensure that the
meaning of the questions was not lost during the translation process.
Measures of Variables and Constructs
The dependent variable Internet usage (IU) was measured with a
single item that represented the number of hours devoted to the usage of
Internet per day. The independent variables included three constructs:
perceived ease of use (PEOU) measured using 5 items, perceived
usefulness (PU) measured using 5 items, and perceived of internet
content (PIC) measured using 4 items.
The external variables considered in this study were gender (GEN),
educational background (EDBACK), family-monthly income (INC),
self-reported knowledge about computers (KNOWL), Internet cost (ICO),
and Internet availability (IAV). The above external variables were
operationalized as follows:
Gender is a dummy variable that takes on a value of 0 for males and
a value of 1 for females.
EDBACK is a dummy variable that takes on a value of 0 for business
majors and 1 for other majors.
INC is a dummy variable that takes on a value of 0 for low
family-monthly income and 1 for high family-monthly income.
KNOWL is a dummy variable that takes on a value of 0 for very
good-to-excellent computer knowledge and 1 for poor-to-good computer
knowledge.
ICO is a dummy variable that takes on a value of 0 for
expensive-very expensive and 1 for very cheap-fair.
IAV is a dummy variable that takes on a value of 0 for very
good-excellent and 1 for fairgood.
Regression Models
Three regression models were used to test hypotheses (H1-H12f). The
average of the items for each construct was used in the regression
analysis. The external variables were included in the multiple
regression equations as dummy variables. We evaluated their effects on
the relationship between PEOU, PU, PIC and IU by adding the interaction
term between the external variable and each of the independent
variables.
Model 1: IU = [[alpha].sub.1] + [[beta].sub.1] (PEOU) +
[[beta].sub.2](PU) + [[beta].sub.3](PIC) + [e.sub.1]
Model 2: IU = [[alpha].sub.2] + [[beta].sub.1] (GEN) +
[[beta].sub.2](EDBACK)+ [[beta].sub.3](INC) + [[beta].sub.4](KNOWL) +
[[beta].sub.5] (ICO) + [[beta].sub.6](IAV) + [e.sub.2]
Model 3: [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII]
Where:
IU: Internet usage
PEOU: Perceived ease of use
PU: Perceived usefulness
PIC: Perceived Internet content
GEN: Gender
EDBACK: Educational background
INC: Family-monthly income
KNOWL: Self-reported knowledge about computers
ICO: Internet cost
IAV: Internet availability
e: error term
DATA ANALYSIS
Characteristics of the Samples
One-hundred sixty nine Chilean students and 194 Emirates students
returned completed surveys. This represented response rates of 56 and 65
percent respectively. A summary of frequency distributions by country
for relevant variables is presented in Table 1.
Seventy-eight percent of Chilean students were males, compared with
49 percent in the Emirates sample. In both samples, students were
undergraduate and younger than 30 years old. Forty-six percent of
Chilean and 69 percent of Emirates students had business majors.
Forty-seven percent of Chilean students and 25 percent of Emirates
students had low family incomes. Ninety-five percent of students in
Chile and 96 percent of students in UAE reported having a computer at
home. Seventy-nine percent (127/160) of Chilean students who had
computers at home also had access to the Internet from home, as did 72
percent (139/186) of the Emirates students.
Thirty percent of Chilean, compared to 59 percent of Emirates
students, stated that their knowledge about computers was very good to
excellent. Six percent of Chilean compared to 4 percent of Emirates
students reported that their knowledge was poor to fair. Some 64 percent
of Chilean students compared to 37 percent of Emirates students
indicated that their knowledge about computers was good. This should be
of no surprise, since more than one-half of the students, in both
countries, used computers over two hours per day. Thirty-seven percent
of Chilean, compared to 56 percent of Emirates students, used the
Internet for more than two hours per day, mostly for class-related
activities and communication (e-mail). Shopping on line was reported to
be the least-used activity on the Internet in both countries. However,
approximately 50 percent of students in both countries used the Internet
for entertainment activities. While the majority of students in Chile
reported that the cost of the Internet was "expensive-very
expensive", the majority of students in UAE indicated that the cost
of the Internet was "fair". Additionally, two-thirds of
Chilean felt that the availability of the Internet in their country was
"poor-good", while three-quarters of Emirates students felt
that the availability of the Internet in their country was "very
good-excellent".
Validation of the Measures
Exploratory factor analysis and Cornbach's alpha were used to
assess the psychometric proprieties of the scales. Factor analysis
(Principal component, with Varimax rotation) was performed to confirm
that the items loaded according to the proposed model. According to Hair
et al. (2006), the acceptable value for factor loading for a sample size
of 150 is 0.45. Thus, items with loading less than 50 percent were
dropped from further analysis. As a result, two items were dropped from
each of PEOU, PU, and PIC. Appendix A presents the results of factor
analysis and Appendix B shows the items and their descriptions that were
used in the computations. Scale reliability was measured using
Cronbach's alpha coefficient. As shown in Table 2, the values of
alpha for the two samples ranged from 0.62 to 0.83. These values are
considered to be sufficient according to Hair et al., 2006.
THE RESULTS OF THE STUDY
The results of the study are divided into three sections. The first
section discusses the relationships between the usage of the Internet
and PEOU, PU, and PIC. For each country, the multiple regression
procedure was employed to test the hypotheses ([H.sub.1]-[H.sub.3]). The
second section analyzes the direct effect of the external variables of
gender, educational background (business vs. non-business), income level
(low vs. high), a self-reported measure of computer knowledge (very
good-excellent vs. poor-good), Internet cost (very cheap-fair vs.
expensive-very expensive), and Internet availability (fair-good vs. very
good-excellent) on Internet usage (hypotheses [H.sub.4]-[H.sub.9]). The
third section reports the impact of the external variables on the
relationship between PEOU, PU, PIC and usage of the Internet (hypotheses
[H.sub.10a]-[H.sub.12f]).
Before testing the hypotheses, the assumptions of the multiple
regression models were validated. Several tests such as
multicollinearity, autocorrelation, plotted histogram, and the plots of
the dependent variable against each of the independent variables were
conducted. Multicollinearity was not a problem since the variance
inflation factor (VIFs) were low (< 2.0) for both samples.
Autocorrelation problem was not an issue since the D.W. values ranged
from 1.80 to 1.96. The plotted histograms of the data depicted a normal
distribution. Additionally, the plots of the dependent variable against
each of the independent variables showed a linear relationship.
The Impact of PEOU, PU, and PIC on Internet Usage (IU)
Based on the regression results of Model 1 (Table 3), only the
second hypothesis ([H.sub.2]) was supported by the data for both
samples. Thus, PU was a significant predictor of Internet usage (t=
2.068, p= 0.04 for UAE, and t=2.104, p= 0.037 for Chile). On the other
hand, PEOU (t= 1.292, p= 0.198 for UAE, and t= 0.151, p= 0.880 for
Chile) and PIC (t= -0.636, p= 0.526 for UAE, and t= 0.663, p= 0.508 for
Chile) were not significant in predicting Internet usage.
The Impact of External Variables on Internet Usage
In this section, hypotheses ([H.sub.4]-[H.sub.9]) were tested using
multiple regression procedure as described earlier in Model 2. As shown
in Table 3, two external variables had significant impacts on the
Internet usage. Gender had significant impact on Internet usage for the
case of the UAE sample (t = 2.312, p = 0.022). Female students in UAE
would spend more time using the Internet compared to their male
counterparts ([H.sub.4] was supported). For the case of the Chilean
sample, self-reported knowledge about computers was a significant
variable that impacted student's Internet usage (t = -2.605, p =
0.009). Chilean students who rated their knowledge about computers as
"poor-good" would spend less time using the Internet compared
to those who rated their knowledge "very-good-excellent"
([H.sub.7] was supported).
The Moderating Effect of the External Variables
In Model 3, the interaction terms between PEOU, PU, PIC and the
external variables (gender, educational background, family-monthly
income level, self-reported knowledge about computers, Internet cost,
and Internet availability) were regressed to determine the role of the
external variable in moderating the relationship between PEOU, PU, and
PIC and Internet usage ([H.sub.10a]-[H.sub.12f])
As shown in Table 3 at the end of the text, only one interaction
term was significant that is (PU *income) for both samples; UAE (t =
2.132, p = 0.035) and Chile (t = 2.211, p = 0.029). Therefore, all
hypotheses (H10a-H12f) were not supported with the exception of H11c
(The impact of perceived usefulness on Internet usage depends on income
level). PU affected usage of the Internet more positively for Emirates
and Chilean students with high-income level than it did for those
students with low income.
DISCUSSION AND CONCLUSIONS
This study investigated the effect of PEOU, PU, and PIC on
students' usage of the Internet in Chile and UAE. It also examined
the direct impact of external variables such as gender, educational
background, family-monthly income, self-reported knowledge about
computers, Internet cost, and Internet availability on Internet usage.
Additionally, the study evaluated the moderation role of the external
variables in the relationship between PEOU, PU, and PIC and IU.
Table 4 shows a comparison between the results of this study and
the results of Alshare et al. (2005a) study that was conducted in the
U.S. The results showed that while PU was the only significant predictor
of Internet usage for both Emirates and Chilean students, PEOU and PU
were significant predictors of Internet usage for American students. It
seems that students in the three countries regardless of their
differences of cultural backgrounds felt that the use of Internet would
be beneficial to them. On the other hand, American students, compared to
Emirates and Chilean students, felt that the ease of use of Internet
motivated them to use it more frequently. An explanation for this
finding is that Emirates and Chilean students, compared to American
students, would be more dependent on their teachers according to
Hofstede's cultural dimensions (Alshare et. al. 2005b), and they
expect support and help from their teachers. Thus, PEOU was not an
important factor in predicting Internet usage. On the other hand,
American students are more dependent on themselves in learning how to
use the Internet; therefore, PEOU was a significant factor in predicting
Internet usage. Another plausible suggestion might be that Emirates and
Chilean students believed in the importance of using the Internet
regardless of its learning difficulty. On the other hand, American
students felt that the difficulty level of learning how to use the
Internet was a major factor that influenced their usage of the Internet.
According to the results of Alshare et al. (2005a) study, PEOU was the
most influential factor that affected American students' usage of
the Internet.
Even though PIC was found to be a valid and reliable construct, it
did not significantly affect students' usage of the Internet. Once
again this finding was consistent with Alshare et al (2005a) findings.
This outcome should be of interest to instructors. It appeared that
students considered Internet content as a trusted source for
class-related activities. The role of instructors becomes more important
to show students the correct way for obtaining quality information on
the Internet. One explanation for not having PIC as a significant factor
could be the fact that the Internet is considered by many students to be
the most convenient way of finding information for class-related
activities; therefore, students may not have much concern about the
actual content.
With respect to the impact of external variables, educational
background (business vs. non-business), family-monthly income level (low
vs. high), Internet cost (very cheap-fair vs. expensive-very expensive),
and Internet availability (fair-good vs. very good-excellent) did not
influence students' usage of the Internet in the three countries as
shown in Table 4. One can say that most of the teachers in many academic
majors do request their students to utilize the Internet as a source for
information; thus, educational background was not significant. As
mentioned earlier and as shown in Table 1 the majority of students used
the Internet for class related activities and communication (email).
Since access to the Internet is available to all students in the three
countries at their schools, income level, Internet cost, and Internet
availability were not significant factors.
While gender significantly influenced Emirates students' usage
of the Internet, self-reported knowledge about computers (very
good-excellent vs. poor-good) significantly influenced American and
Chilean students' usage of the Internet as reported in Table 4. As
expected students with greater knowledge about computers would feel at
ease in utilizing computer applications such as the Internet; and
therefore, use it more frequently. While it might be easier to explain,
based on the "gender gap" concept, why male students, compared
to female students, would spend more time using the Internet, it is not
quite easy to explain why Emirates female students would spend more time
using the Internet. One explanation could be based on the UAE culture.
According to Hofstede's cultural dimensions, the culture of the
Arab countries, which UAE is one of them, is a conservative society
(Alshare et al. 2005b). Therefore, Emirates female students, compared to
their male counterparts, would use more frequently the Internet for
communication (email); especially with their teachers. Additionally,
Emirates female students who live on campus are limited in their social
interactions outside the campus; therefore, the Internet would be their
social outlet.
As shown in Table 4, family-monthly income level was the only
significant moderator in the case of UAE and Chilean samples. It
moderated the impact of PU on Internet usage. On the other hand, gender
was the only significant moderator in the case of the American sample.
It moderated the relationship between PEOU and Internet usage. PU
influenced usage of the Internet more positively for Emirates and
Chilean students with high income level than it did for those students
with low income. It is reasonable to assume that people with high income
level would have access to the Internet at home or Internet shops; and
thus, they use the Internet more often for a variety of reasons, and
they would appreciate its usefulness. As a matter of fact, the majority
of students with high income level spend more than 4 hours per day using
the Internet, while the majority of students with low income level spend
lees than 3 hours. On the other hand, Income level was not a significant
moderator for American sample because the Internet cost, compared to the
cost in UAE and Chile, is considered cheap. Thus, both groups of income
levels could afford to have internet access at home; and therefore,
appreciate its usefulness. As reported by Alshare et al., (2005a) PEOU
influenced usage of the Internet more positively for American female
students than it did for males. Female students felt that the ease of
use of the Internet, but not necessarily its usefulness or its content,
motivated them to use the Internet more frequently. However, for
Emirates and Chilean students this was not the case. The impact of
gender on the relationship between PEOU and Internet usage was not
significant.
Finally, the results revealed that an extended TAM model was
partially valid in non-western cultures such as Chilean and Emirates
cultures. Only PU impacted student's usage of the Internet
regardless of their cultural backgrounds. Therefore, educators need to
reinforce this concept (perceived usefulness) especially when deciding
to teach online classes. Instructors might request students to use the
Internet more frequently and demonstrate how easy it is for them to find
the desired information.
The limitations of the study includes: first, the reliance on
self-reported data on all constructs. Thus, relationships among the
constructs might be inflated. Second, the use of students as the target
population restricts the ability to generalize the results. Therefore,
future research might use a more detailed questionnaire survey with a
follow up with subjects. Another future research might be targeting all
population segments; and thus, results of the study could be
generalized. Finally, another plausible future research could be
examining the impact of cultural dimensions on the proposed model by
including constructs that represents cultural dimensions.
