INTERACTION OF HYPERTEXT FORMS AND GLOBAL
VERSUS SEQUENTIAL LEARNING STYLES
ANDREAS DÜNSERMARCO JIRASKO
University of Vienna, Austria
ABSTRACT
In this study, the relevance of the distinction between sequential and global
learners in the context of learning with hypertext was investigated. Learners
with global learning style were expected to produce better results when
learning with hypertext, whereas learners with sequential learning style
should profit from a structural aid in form of a suggested path through the
document. In a learning experiment the influence of learning style (global
versus sequential) and an additional suggested path through the document on
learning achievement with hypertext was empirically tested. The main result
was that sequential learners showed poorer results when learning without
suggested path, global learners achieved the same results in both text condi-
tions. When learning with a suggested path, both learning styles achieved
equal results. We conclude that students with sequential learning style are
at no disadvantage when learning with hypertext as long as they can rely
on an additional path.
USING HYPERTEXT FOR LEARNING
Even before hypertext was realized, visionaries like Vanevar Bush (1945) had
the idea of linking information in non-linear fashion to provide new possibilities
for the presentation of knowledge. In contrast to traditional written media like
books, in which the chapters and information are presented in fixed sequence,
hypertexts offer many different methods of presenting and assimilating infor-
mation. Instead of a linear sequence the reader gets a linked, non-linear organi-
zation of knowledge. Single information units or knots are connected through

links in many different ways (e.g., hierarchically). One does not “read” this
document, one navigates through it.
These new possibilities for organizing information have been and are still being
used for creating learning environments. Different forms of computer-based
learning have been developed and used. Hypertext differs from other systems, like
CAI (Computer Aided Instruction) or CAL (Computer Assisted Learning), in that
hypertext is not directive but normally leaves the control to the user (Gall &
Hannafin, 1994). In a hypertext environment, the learner is able to decide which
information he/she wants to get next. So the user can find his/her individual
path through the document, and the program does not lead him/her in a certain
direction or to a certain goal.
Many authors think that hypertext provides advantages for the construction of
learning environments, such as the possibility of integrating other media or linking
different resources. Another argument in favor of hypertext which is frequently
quoted (Freisler, 1994; Kuhlen, 1991; Schulmeister, 1997) is that the net-like
structure of knowledge in hypertext corresponds to the net-like organization
of human brains. This comparison has not been proven in experiments (see
Gerdes, 1997).
The disadvantages of hypertext have also been reported. Problems like being
“lost in hyperspace,” or cognitive overhead (acquiring information and taking
navigation decisions at the same time) (Conklin, 1987) must be considered. In
comparison to traditional linear text, hypertext often proves disadvantageous in
learning experiments (Britt, Rouet, & Perfetti, 1996). But whether this is because
people cannot learn as well with net-like organized information, or because
hypermedia literacy still is too low (Jonassen & Grabinger, 1990) cannot be
answered clearly at the moment. The problem with most of these experiments
is that linear texts, which are meant to be read in a linear fashion, are converted
into hypertext. This of course can lead to problems in understanding.
The real potential of hypertext, however, lies in its flexibility of knowledge
presentation and adaptability for different learners. Matching of individual learn-
ing preferences and form of knowledge presentation has been found to facilitate
learning (Graff, 2003; Pask, 1988). By using hypertext to design instructional
material, individual differences in learning can be addressed. Considering these
individual differences, it is important to investigate how different structures and
organization of information can contribute to improve learning (Bajraktarevic,
Hall, & Fullick, 2003).
HYPERTEXT AND LEARNING STYLES
Learning styles can be described as the habitual use of a set of similar strat-
egies. Thus they indicate a learner’s learning behavior, which is more or less
stable (Ramsden, 1988). Learning styles are not fixed characteristic features of
a person’s personality, but an orientation to learning that gains certain stability.
80 / DÜNSER AND JIRASKO
Different theories and models of learning styles and learning strategies have
been discussed and examined in the context of learning with hypertext. In some
studies, Kolb’s Learning Style Inventory (see Kolb, 1984) which distinguishes
between “Divergers,” “Assimilators,” “Convergers,” and “Accommodators”
was used to measure individual differences (e.g., Kraus, Reed, & Fitzgerald,
2001; Melara, 1996; Reed, Oughton, & John, 1998). Beishuizen and colleagues
(Beishuizen, Stoutjesdijk, & van Putten, 1994; Beishuizen, Stoutjesdijk, &
Zantnig, 1996) used the “Dutch Inventory of Learning Styles” (ILS) (see Vermunt
& van Rijswijk, 1988) which measures deep and surface processing to assess
learning style. These studies were designed as hypertext learning experiments
or studied differences in navigation or searching tasks. Most of them did not
show clear effects with respect to differences in learning achievement or navi-
gational behavior.
In some hypertext studies cognitive style (field dependence vs. field inde-
pendence) was additionally assessed (e.g., Federico, 2000; Reed, Oughton,
Ayersman, Ervin, & Giessler, 2000) or was the main focus of interest (Lin &
Davison-Shivers, 1996; Liu & Reed, 1995). Only in some studies, effects of
cognitive style were found. Lin and Davison-Shivers (1996), for example, showed
that field-independent subjects achieved better results in a hypertext learning
experiment.
The way that hypertext documents can be studied suggests other sources
of individual differences and especially learning styles. Traditional learning
materials are normally read and studied linearly in a given sequence. Hypertext,
on the contrary, can be read in many different ways and sequences. Therefore
the differentiation between global and sequential learners seems especially
relevant in this context.
Riding and Grimley (1999) presented a model that differs between wholists
and analytics, showing that analytics did better on traditional material than multi-
media. Ford and Chen (2000) found no significant correlation between these
cognitive styles and learning outcomes with hypertext. However this differen-
tiation following the Riding paradigm seems rather to be linked to field depen-
dence vs. field independence than to learning styles in particular as the way it
is assessed (by Riding’s Cognitive Style Analysis) is very similar to Witkin’s
Group Embedded Figures Test (Witkin, 1991)
Felder’s (1993, 1996) model of global vs. sequential learning style is based on
research by Pask (1976, 1988), who termed these learners holists and serialists.
Learners with sequential learning style like to learn step by step and prefer linear
and logic structure. Learners with global learning style do not necessarily follow
the given sequence, jump between passages, and try to identify the general
perspective from the beginning on. Using Felder and Silverman’s “Index of
Learning Styles” (Felder, 1996), Bajraktarevic, Hall, and Fullick (2003) found
that students achieved higher scores when they studied with a hypertext struc-
ture that matched their learning style. The matching hypertext for global learners
HYPERTEXT FORMS AND LEARNING STYLE / 81
included different elements such as diagrams, tables of contents, overviews,
etc., the one for the sequential learners consisted of text-only pages with
“forward” and “back” buttons.
RESEARCH AIMS AND OBJECTIVES
In the present study, we examined the effect of structural aid on learning
achievement of students with global and sequential learning styles. We wanted
to alter the stimulus material as little as possible in order to maintain compara-
bility and not to transform hypertext to a strictly linear format. It seems likely
that sequential learners would have difficulties when learning with hypertexts
with a lack of linear structure. With a structural aid, such as an additional
suggested path through the document, these problems should diminish. Global
learners, in contrast, should profit from the non-linear format. They can navigate
through the document as they want and do not have to turn one page after the
other. An additional path through the document should not help global learners
to achieve better learning results.
The following hypotheses were tested.
1. Students with global learning style show better learning results when
learning with hypertext.
2. Students learning with a hypertext with an additional linear path through the
document achieve better learning results when learning with hypertext.
3. Especially students with sequential learning style achieve better learning
results when an additional linear path through the document is available.
Interactions between prior knowledge, hypertext form, and achievement should
also be examined. Knowledge of the subject is important to get oriented in
hypertexts and to make navigation decisions (Gall & Hannafin, 1994; Tergan,
1997). Furthermore, studies indicate that students with little prior knowledge
can profit from linear structures (see Gerdes, 1997). These linear structures
should help them to build up a coherent understanding of the subject. So we
additionally investigated whether additional aid (path through the document)
leads to better learning results in participants with low prior knowledge.
METHODS
Development of a Learning Style Questionnaire
First of all, a questionnaire to distinguish global from sequential learners was
constructed, since none existed in German. Items from the scale “sequential vs.
global understanding” from Felder and Silverman’s “Index of Learning Styles”
(Felder, 1996) were translated and rephrased. As some items could not be properly
82 / DÜNSER AND JIRASKO
translated, and in order to increase the focus on global vs. sequential learning style,
self-constructed items were added. Here are two sample items:
Global learning style: “When learning with a textbook, I do not necessarily
stick to the given chapter sequence.”
Sequential learning style: “When I am working on a problem, I prefer to
solve it step by step.”
This questionnaire was pre-tested on a sample of 77 students. The analysis
showed that global and sequential learning style are opposite poles of one
single factor. So we were able to construct a questionnaire (Dünser & Jirasko,
2000) that distinguishes between global versus sequential learning style. After
selection of items the resulting 14-item questionnaire had a Cronbach’s alpha
of � = .65, which is at the lower limit of satisfaction.
Hypertext Learning Experiment
With this experiment, we examined whether students with global learning
style and students with sequential learning style showed different learning
achievements when learning with hypertext, and if any influence of a structural
aid (additional linear path through the text) could be observed.
Materials
The Learning Text—The hypertext used for the experiment was constructed
with HTML (Hypertext markup language). This form of hypertext was used
because it is one of the most common forms of hypertext (e.g., on the WWW)
and most people are familiar with it. In other words, sufficient hypermedia
literacy could be expected.
The hypertext document dealt with the topic “hypertext” and with permission
from the author Stefan Münz, the text had been adapted for the experiment. The
original document (Münz, 1997) contained an additional path through the text.
Participants could follow this path by clicking on an arrow pointing to the right at
the bottom of each page to continue. There was also an arrow pointing to the left
hand side to go back (this was no history-back, as offered by the browser, but could
be used to go back in the path). This suggested path was not meant as a logically
linear path,1 but a suggestion, as the author called it. So it cannot be equated with
“turning the pages,” but must be seen as an additional aid for navigation and
orientation. Two identical forms of the text were created, where one contained this
path, in the other it was removed.
HYPERTEXT FORMS AND LEARNING STYLE / 83
1 A logically linear path is not possible in a real hypertext document, where each knot has to be
an information unit in itself (Kuhlen, 1991).
Questionnaires
In addition to the learning style questionnaire, other questionnaires were
developed for the learning experiment. Thirty multiple-choice questions on
hypertext were designed to measure the knowledge acquired from the text. The
participants were presented with these questions before and after the learning
phase in order to measure prior knowledge of the topic and learning effects.
To investigate depth of processing, a mix of questions on facts (e.g., “Which
term is used to describe an information-unit?”) and questions that measured
understanding/comprehension (see Bloom, 1956) (e.g., “What is the fundamental
difference between traditional text and hypertext?”) were presented. Whereas
the questions on facts could be answered by only reading the text, the questions
on understanding could only be answered after having understood certain
concepts and connected different ideas. With respect to prior knowledge, we
assumed that the subjects knew rather little about the topic.
Additional variables collected were demographical data (age, sex, subject
and duration of studies), and questions on experience with and attitude toward
learning with hypertext and computers. After the learning phase, the students
answered questions on how they liked learning with this medium and whether
they had experienced any problems.
Subjects
Eighty-six Viennese university students took part in the experiment, 63 of
them studying psychology, 7 technical sciences, and 16 social sciences. All
participants were Caucasian which is typical for the Austrian student population.
Thirty-four students were male and 52 female, with an average age of 26 years
(SD = 5.25). Most of the students participated on a voluntary basis, and some did
as part of a university class.
Design
The experiment took place in group sessions in a computer classroom at the
University of Vienna. Group size for a session was limited to a maximum of 20
people, as 20 computers were available in the classroom. Nine of the recruited
students could not take part in the experiment in the computer classroom because
of their personal schedule, so they participated via Internet. This was possible
because all the materials were also available online and the instructions could
be retrieved online. After a review of the data, all the participants could be
included in the analysis.
In the first questionnaire the students were presented with questions on
learning style and demographical data. The second questionnaire consisted
of questions on experience with and attitude toward learning with hypertext
and the knowledge questions. Afterwards the subjects were randomly assigned
84 / DÜNSER AND JIRASKO
to one of the hypertext forms. The maximum duration of the learning
phase was limited to one hour. After this phase the knowledge questions,
the questionnaire on learning style, and the additional questions were pre-
sented again.
Results
Forty-two students (48.8%) learned with the hypertext with the additional path
and 44 (51.2%) with the hypertext without path. The distinction between the two
learning styles was made by a median split. This resulted in 46 persons (53.5%)
with global learning style and 40 (46.5%) with sequential learning style. The
combination of the two hypertext forms and the learning styles produces four
condition groups with almost the same number of students.
The duration of the whole experiment was one hour and 23 minutes on
average, and the learning phase took 47 minutes on average. The time spent
for learning showed no significant differences in the four treatment groups
F(1, 81) = 0.97, p = .33.
We tested the hypotheses using a three factorial analysis of variance with one
repeated-measures factor and two between-groups factors. The repeated-measures
factor was knowledge before and after the learning phase, the between-subject
factors were hypertext form and learning style. The increase in knowledge
was significant F(1, 82) = 528.14, p < .01. On average, the students were able to
answer 10 questions more after the learning (before learning phase M = 8.34,
after learning phase M = 18.12; out of 30 questions). Regarding hypertext form,
F(1, 82) = 0.40, p = .53, and learning style, F(1, 82) = 0.16, p = .69, no significant
differences could be observed. Therefore the statistical results indicate no support
for hypothesis 1 and hypothesis 2.
There was, however, an interaction between the three factors achievement,
hypertext form, and learning style F(1, 82) = 4.61, p = .04 (see Figure 1).
Contrasts revealed that sequential learners without path showed a smaller gain
in knowledge than the other groups t(82) = 1.77, p = .04. Thus students with
a sequential learning style achieved better results in the hypertext learning
experiment when they had an additional path at hand. The absence or presence
of this additional path, however, did not have any influence on the learning
achievement of global learners. This indicates support for hypothesis 3.
These results show that neither hypertext form nor individual learning
style lead to different learning results on their own, but there is an interaction
between these variables in their effect on learning achievement. Sequential
learners learned significantly less when no additional path through the hypertext
document was provided.
As described above, the questionnaire for the knowledge test contained
questions on facts and on understanding. An ANOVA with fact knowledge
before and after as repeated-measures variable and hypertext form and learning
HYPERTEXT FORMS AND LEARNING STYLE / 85
style as between subject factors showed only a significant increase in knowledge,
F(1, 82) = 442.38, p < .01. The same analysis with understanding-scores again
showed significant results in the increase of knowledge, F(1, 82) = 264.29, p < .01,
but also showed an interaction between all three factors: achievement, hypertext
form, and learning style, F(1, 82) = 5.84, p = .02. Thus sequential learners gained a
better understanding but not more fact-knowledge when they could learn with the
additional path, t(82) = 1.77, p = .04. Students with global learning style did not
show any differences in the two hypertext conditions. This lead to the conclusion
that students with sequential learning style depend on structural aid especially

when understanding is required. For learning facts, the additional path does not
lead to better learning achievement.
In a further step we examined the interaction between prior knowledge,
hypertext form, and achievement. The groups for prior knowledge (high versus
low) were divided by median of the pretest knowledge score (MD = 8.4). An
ANOVA with knowledge before and after as repeated-measures variable and
prior knowledge and hypertext form as between subject factors was executed.
No interaction between prior knowledge, hypertext form, and achievement could
be observed.
The analyses of the additional questions showed that most of the students
enjoyed learning with hypertext, but the majority preferred learning with a
book to learning with hypertext. A significant difference could be observed
in the self-rated knowledge about hypertext before and after the experiment,
t(84) = –9.05, p < .01. The students felt they had learned something after the
experiment. The self-rated knowledge after the learning phase was significantly
correlated (r = .50, p < .01) with their judgment of how well they had done in
the knowledge questions.
About half of the participants reported various problems when learning with
the hypertext. However, this question was not correlated with learning achieve-
ment (r = –.03, p = .82). The students mentioned the following problems: learning
from a screen, concentration, the representation of information in hypertexts,
and gaining an overview.
Discussion and Conclusion
In this experiment we found that individual differences in learning and the
presence or absence of structural aids in hypertexts have interactive effects on
learning achievement. Learning style and an additional path in the document do
not have a global influence on how much students can learn from hypertext.
However, students with a sequential learning style show better learning results
with the hypertext form that contains structural aid. Thus students who normally
read and learn step by step, and like logically structured information, can profit
from hypertext better when an additional path through the document is offered.
This path does not have any influence on the achievement of students with global
learning style.
The advantage of the additional path for students with a sequential learning style
can be observed in their understanding of the topic. With respect to knowledge of
facts, this interaction is not significant. We believe that students with a sequential
learning style depend on linear structures to build up their understanding of a
subject. When they do not find this structural aid they can learn the facts, but
seem to have difficulty in understanding the information. Gerdes (1997, p. 77)
HYPERTEXT FORMS AND LEARNING STYLE / 87
proposed, that linearly structured information helps learners with little previous
knowledge in the process of understanding (see also Gall & Hannafin, 1994;
Tergan, 1997). In this experiment, we did not find this for students with little
prior knowledge, but for sequential learners.
It is often argued that additional aids and structures in hypertexts can
improve learning and support learners with different preferences (see Astleitner,
1997; Ford & Chen, 2000; Sadler-Smith & Smith, 2004; Schroeder & Grabowski,
1995). The findings of this study can be an argument for creating hyper-
medial learning environments with additional navigational aids like a sug-
gested path. Using such aids, hypertexts can be constructed to serve students
with different learning preferences. With a path, which does not diminish the
achievement of global learners, the disadvantages of sequential learners could
be leveled out.
Teaching is much more efficient when it corresponds to the students preferred
learning strategies (Pask, 1976). Studies have shown (Bajraktarevic et al., 2003;
Graff, 2003) that learning results were better when hypertext structure and
learning preferences were matched. As hypertexts provide much flexibility in
information presentation and normally can be read in different ways, there is a
big potential in this medium. Regarding the improvement of learning Marton
(1988) wrote: “We should make up our minds about what kind of learning
we value and then build an educational system that works toward that goal” (p. 78).
In Felder’s (1993) opinion, efficient teaching must address each pole of each
learning-style dimension. So teaching materials could be improved by integration
of different aspects that support students with individual preferences. This requires
students to realize their own learning preferences and to be able to choose the
learning environment that best suits them, which Biggs (1988) described as
“metalearning.”
According to Ramsden (1988), the possibility to choose the learning environ-
ment can also be positive for students’ motivation for and interest in learn-
ing. Additional teaching and navigation aids do not have to be useful to all
students in the same way (Schroeder & Grabowski, 1995), but can be very
useful for some.
These suggestions for the design of instructional material become increasingly
relevant, as more of these materials are developed using hypertext. In times
where concepts such as e-learning are getting more important and more fre-
quently used, these issues have to be addressed. Because of the sample
characteristics, the findings of this study are somewhat limited to conclusions
in the field of higher education and for students with little prior knowledge of
the subject. To investigate their generality in a broader population, studies using
other subjects seem desirable.
Further studies should investigate students’ navigational behavior in corre-
spondence to their learning styles and preferences. It would be interesting to
88 / DÜNSER AND JIRASKO
study, for example, whether students with sequential learning styles really produce
more linear navigation patterns when navigating through a hypertext.
