        <p>This article presents the results of an empirical study aimed in researching the online activity of pupils who prefer a smartphone as a tool for solving educational tasks (n=582). It shows that the online learning activity of 6th - 9th grades pupils who prefer a smartphone is less diverse, in comparison with those who prefer to use a computer or a laptop. Also pupils who use a smartphone for solving educational tasks are more likely to turn to ready-made answers.</p>

      <title>Introduction</title>
      <p>pupils’ attitude to their educational activity. The questions “how” and “why” are interconnected in
this case. That’s why the research question about the educational activity characteristics of pupils
preferring different devices will be answered in the context of studying motivation and results of using
a computer, laptop, tablet and smartphone.

      <title>Literature Review</title>
      <p>The modern world is permeated with digital technologies. Even before the COVID-19 pandemic,
people could not imagine their lives without smartphones, laptops and tablets [Yasakcı et al., 2019].
It seems that the children of generation Z are born with a smartphone in their hands. Since the
beginning of 2010s preschool institutions using digital technologies for the education and
development of children have appeared in different countries [Park et al., 2021], [S renssen et al., 2021].
If earlier it was recommended to use computers or laptops or tablets like educational tools but
now smartphones are becoming learning tool everywhere [Vorley et al., 2016], [Jeong et al., 2017],
[Bolliger et al., 2021]. Smartphones are more familiar, easier to use, faster and with more applications
for learning [Barkley et al., 2021]. Smartphones are multi-tasking and that’s why they can be used
in different educational directions [Grinols et al., 2014]. They are suitable for a distance education,
a personalizing education, group learning in classes [Annamalai et al., 2020]. The predictors of using
smartphones as an educational tool are small effort, performance, social influence, perceived
playfulness, self-management of learning [Anshari et al., 2017]. Sometimes teachers doubt whether pupils
are looking for educational information or communicating in social networks by smartphone in classes.
And parents tend to have the same concern at home. But pupils using smartphones as an educational
tool feel themselves modern and socializing [Andrew et al., 2018], [Sari et al., 2020]. This situation
gives any doubts about usefulness of smartphones as an educational tool [Moorleghen et al., 2019].</p>
      <p>Some scientists argue that in some cases the smartphone education is more effective than the
lecture learning [Kim et al., 2017], [Price et al., 2014], [Tossell et al., 2015]. Part of them explains
it by the fact that to be effective education has to fulfill pupils’ developmental and comfort needs
[Williams et al., 2011]. For example, modern students are used to reading from laptop or
smartphone screen [Bana, 2020], [Barkley et al., 2021]. But understanding information is better if it is
given at a paper source [Ackerman et al., 2012], because nobody reads e-books or sites thoroughly
[Noorhidawati et al., 2008]. Therefore, developers of websites and e-books are working on navigation
systems so that only the necessary information can be read. Even though it is well-known that the
integral perception of information to be read develops cognitive skills. The gamification of learning
tasks in smartphone apps is new educational trend [Clayton et al., 2016]. No doubt, it increases
positive emotional affect from task deciding and reduced subjective effort experienced by students
[Bernecker et al., 2021], [Sumitra, 2019]. This and other upgrades led us from e-learning to m-learning
as a more perspective [Wang et al., 2009], [Sykes et al., 2014].</p>
      <p>But most researchers express concern about using smartphones as educational tools
[Cordes et al., 2000]. These opinions are supported by the results of psychological studies of
both normal and problematic smartphone use. Smartphones are becoming an extension or a
part of the person [Park et al., 2019], [Ross et al., 2021]. It is the straight road to the
digital person [Pancani et al., 2020]. It seems the human being is going away. The real emotions,
talking “face to face” etc. concede to messengers, social network, digital games and
entertainments [Verduyn et al., 2021]. The quality of real communication between lovers, friends and
partners decreases at the moment smartphone presence with them [Amichai-Hamburger et al., 2016],
[Misra et al., 2016]. It is shown, for example, that the simple presence of a smartphone may limit
cognitive recourses and attention, necessary for any task solving, by a wish to check the device or
trying to avoid it [Ward et al., 2017].</p>
      <p>Now problematic smartphone use is worldwide known. Even preschool children (near 17%) have
problematic smartphone use; they watch video, listen to music, take a pleasure and lose self-control
[Park et al., 2021]. Some changing appeared in preschool children cognitive skills connecting with
using smartphones [Johnson, 2006]. For example, the selective attention is better developing than
divided attention [Konok et al., 2021]. Negative effects of using a smartphone increase in school
childhood. Researchers state that pupils using smartphone more than four hours a day have a low
quality of sleep [Anshari et al., 2017]. Such changes in sleeping correlate with self-regulation low level
appearing with non-control smartphone using. Reasons of problem smartphones using by adolescents
are different: the boredom in free time is determined by a need in communication and a hedonistic
motivation [Leung, 2020], conflicts with parents [Matthes et al., 2021], loneliness [Shen et al., 2019]
and low level of subjective and psychological well-being [Horwood et al., 2019].</p>
      <p>Also the problematic smartphone use is predictor of the academic procrastination
[Aalbers et al., 2021] and academic stress [Anshari et al., 2017], [Akinci, 2021]. This is because
adolescents use smartphones for entertainment and communication in social networks but not for
educational tasks solving [Camerini et al., 2020]. The recreation motive of online activity leads to spending
much more time using smartphone by adolescents [Camerini et al., 2020]. In this case,
problematic smartphone using becomes negative predictor of the educational development [Akinci, 2021],
[Verma et al., 2016]. But we argue that the same had been written about laptops and computers
usage some years ago [Fried, 2008] and may be in two-three years problematic smartphone using will
not be seen as a problem [Ellis, 2019]. Thus, the use of a smartphone as a tool for solving educational
tasks is considered ambiguously. Both advantages and concerns are highlighted. However, there are
almost no studies that clarify how the smartphone is used in educational activities when the pupils
are not under the control of parents and teachers. Our research aims to fill this gap.

      <title>Materials and Methods</title>
      <p>The study involved 582 teenagers aged 11-16 years (56.01 % of girls) enrolled in grades 5-9 of schools
in St. Petersburg. The empirical data was collected through a survey conducted using the online tool
“Google Forms”. Pupils were asked to answer the questions presented in Table 1, which suggested the
following possible answers: “Never” (0 points), “Rarely” (1 point), “Sometimes” (2 points), “Often” (3
points).</p>
      <p>In addition to these questions, the questionnaire included items on the availability of various
technical devices (smartphone, tablet, laptop/computer) for solving educational tasks, as well as on
the preferences in using a particular technical device in educational activities. Based on the responses
received, the sample was divided into three subgroups: those with a preference for a smartphone
(n=338), a laptop or computer (n=99), and a tablet (n=12). The last subgroup was excluded from
the analysis due to its small number, as well as students who reported that there was no possibility
to choose a technical device (n=133).</p>
      <p>The results were computed by “Statistica 12.0” software package. Statistical processing included
frequency analysis, average value analysis, criteria analysis (Fischer * criteria), factor analysis.</p>

    <sec id="sec-4">
      <title>Results</title>
      <p>The results we obtained indicate that the preference of a smartphone as the main tool for performing
educational tasks is not connected with the place of study in the structure of pupils’ online activity,
which is quite significantly inferior to communication, recreation and entertainment using of the
Internet. It can be noted that students who prefer a smartphone, report a slightly higher Internet activity
in all areas, in comparison with students who mainly use a laptop or a computer for educational
purposes, but these differences do not reach the level of statistical significance (see Figure 1).</p>
      <p>Further analysis showed that online learning activity of secondary school students, regardless of
the preferred technical device, is dominated by the search for additional and reference information,
as well as, to a slightly lesser extent, the use of online tests and online simulators for self-testing and
preparation for certification activities (see Figure 2).</p>
      <p>At the same time, it was found that schoolchildren who prefer smartphones are significantly
more likely to use such a method of educational tasks fulfilling as searching for ready-made answers,
ready-made papers or ready-made homework, and at the same time significantly less likely to use
the subject-specific educational opportunities of the Internet, in particular, modeling experiments, as
well as the possibility of participating in online subject Olympiads.</p>
      <p>It should be noted that students are much more likely to use conventional search engines for
educational purposes, in comparison with specialized sites designed to solve a variety of educational
tasks. Adults (teachers and parents) become sources of information about the educational
opportunities of the Internet relatively rarely. At the same time, those students who prefer a smartphone
are significantly more likely to turn to specialized sites recommended by friends, which is much less
typical for those who use mainly a laptop or tablet (see Figure 3).</p>
      <p>Factorization of the data (see Table 2) allowed us to note that the online learning activity of
those students who prefer a smartphone is less diverse than those who prefer a computer or a laptop.

associated with information about the educational opportunities of the Internet reported by adults
(Factor 1, the contribution of the factor to the variance of variables 24%), while information received
from friends, as well as their own search efforts, was primarily associated with the search for
readymade solutions (Factor 2, the contribution of the factor to the variance of variables 16%). Students
who prefer to use a laptop or a computer turn to the use of ready-made materials, primarily on
the advice of friends (Factor 3, the contribution of the factor to the variance of variables 11%), use
specialized educational sites following their teachers advice (factor 1, the contribution of the factor
to the variance of variables 22%), look for additional information independently or with the help of
parents (factor 2, the contribution of the factor to the variance of variables 19%).

      <title>Discussion</title>
      <p>According to our study results pupils of grades 6-9, regardless of the device used, give a greater
preference in Internet activity to extracurricular activities: entertainment and communication in
social networks. This distribution of activity is quite natural for teenagers and corresponds to age
norms. Many researchers note that the structure of the motivation also highlights the motives of
communication with peers to a greater extent than one’s own interest and orientation towards teachers
and parents in all deals, including educational tasks [Anshari et al., 2017]. It should be also noted,
that our study participants are ordinary schools students and, perhaps, gifted adolescents would
demonstrate another rating of the Internet activities’ preference. Also pupils preferring smartphone
as the educational tool more often spend the time in the Internet, than their classmates preferring a
computer or a laptop. The reason of such internet behavior may be explained in the context of coping
strategy facing boredom during homework time. The similar fact is described by Barkley and Lapp
[Barkley et al., 2021]. And we can suppose the pupils preferring smartphone are less interested in
learning than teenagers preferring a computer or a laptop. It is confirmed by our other study where
it was shown that pupils preferring smartphone have a lower academic success. If we compare both
results, we can conclude that pupils preferring smartphone have not the high educational motivation.
And we see the pupils preferring a smartphone significantly less frequently take part in subject
Olympiads and simulate experiments but significantly more often search for ready-made solutions or
ready-made homework assignments than their peers preferring a computer or a laptop. We can also
suggest, that students who prefer a computer or a laptop tend to be engaged in more educational
activities directed to develop academic skills, such as using tests-simulators for preparing for tests
and exams, сlasses with tutors, viewing of feature and popular science films necessary for studying.
But this fact needs further exploration. Probably it demonstrates the pupils’ interest in learning and
their aspiration to achieve academic results and success by themselves. Pupils preferring smartphone
search ready information for using and do not need for its additional transformation.</p>
      <p>Adolescents rate referent groups for recommendations of educational information according their
age-specific features. At the first place they value their own opinion and the ability to make their own
choice about sites usage. It is reaction of emancipation which is typical for adolescence. Teachers
occupy the next place because they are considered experts in the field of educational information. And
then we see difference between adolescents preferring a computer or a laptop and their peers preferring
a smartphone. Ones prefer parents’ opinion but others - friends’ advice. This result is interesting
because friends’ opinion is usually more important than parents’ one for adolescents. However we
note that pupils preferring a computer or a laptop have classes with tutors and use tests-simulators.
These kinds of activity are impossible without parents’ taking part, especially financial. And
supposedly, parents do influence their children in the part of educational attitudes and motivation. The
factor structure confirms our assumption: adolescents preferring a computer or a laptop ask for their
parents advice in case of searching additional educational information. And only last of all they
turn to friends who recommend them sites with a ready-made homework. Finally we see the distinct
hierarchy of educational sources and activities of pupils preferring a computer or a laptop: at the
first - expert information and developmental activities, then – additional information had chosen by
parents’ advices and at last – friends with their questionable recommendation. Pupils that prefer
smartphones demonstrated the opposite features. They are friends and ready homework oriented. It
seems normal for this age but it gives us some concern thinking about their future. We may suppose
these adolescents are more separated from adults (teachers and parents) and satisfy their educational
and communicative needs by smartphones.</p>

      <title>Conclusions</title>
      <p>The preference of the smartphone as the main tool for completing educational tasks is not reflected
in the place of educational activities in the hierarchy of pupils’ online activity. But it determines the
content of educational online activity, in which the search for ready-made solutions on the Internet
becomes more important, both independently and based on the significant others advice. We think
that smartphone usage with educational reasons among school students has both positive and adverse
sides regarding educational motivation and adolescence social and personal development in a broader
sense. Future research should further examine smartphone usage among students both with
educational and recreational purposes, we need to develop more specific measures for smartphone usage,
and to form research based interventions to prevent problematic smartphone usage in the context of
students’ educational online activities.</p>
