        <p>The constant inclusion of new digital skills in job positions is evidence of the effects that the accelerated adoption of technology has generated in the labor market because of the pandemic; posing a challenge for the university education system that seeks to train its students to be successfully inserted in jobs. The objective of this study is to compare the dimensions of the digital competence found in the job offers of companies with those present in the syllabus' contents of a university program in Social Sciences, as well as the relationship between academic performance and the level of the indicators of the dimensions of the digital competence. For the study, 20 companies were chosen from the ranking of the 500 largest companies in Peru in 2021 carried out by “América Economía”, 43 syllabi of the program, and the survey was applied to 185 students. In this research, it was found that the understanding of technical concepts, research and visual and/or audible identification indicators present the highest averages, that is, they are the skills most required by companies. Visual and/or audible identification and respect for others have low averages because it is not common to find them in the job offers of the companies, and problem solving has not been found in any of the job offers. These same results were found in the syllabus' contents. More than half of the students are distributed in the high and very high levels, with 04 indicators in which no student is in the low level. We concluded that, despite the high and very high level of the dimensions of digital competence achieved by a high number of the students who participated in our study, it is coinciding with the current requirements of the company; it is imminent not only to reformulate the curriculum that already contains training in digital skills, but also to include it in the curricula that do not consider it, so that the University ensures that its students can successfully face the technological innovations that companies will make in the future.</p>

      <title>1. Introduction</title>
      <p>
        Being part of the knowledge society involves developing digital competence, defined as the skills,
knowledge and attitudes that are required when Information and Communications Technology (ICT)
and digital media are used to solve problems, manage information, create, and share content and build
knowledge [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ]. The markets, companies and productive sectors are highly influenced by aspects such
as globalization and technological development, the latter in exponential growth due to the pandemic
[
        <xref ref-type="bibr" rid="ref2">2</xref>
        ]. This has repercussions on a natural need of the productive sector to request –within their job offers–
high levels of digital competence [
        <xref ref-type="bibr" rid="ref3">3</xref>
        ].
      </p>
      <p>
        The labor market has been analyzed through information collected from online job offers, with Big
Data analysis in this regard in European countries [
        <xref ref-type="bibr" rid="ref4">4</xref>
        ]. Job offers require increasingly specific digital
skills, according to the job position; that is why the coherence between the academic offer and the labor
demand must be reinforced, directing the efforts so that the formal academic training manages to focus
on the needs of the students, workers, and society, innovating teaching and learning in such a way that
respond to the digital age [
        <xref ref-type="bibr" rid="ref5">5</xref>
        ].
      </p>
      <p>
        Analyzing the digital skills that jobs require from graduates is the starting point to represent them in
the syllabi of subjects that form the dimensions of Digital Competence in university students; Research
on curricula at different educational levels is projected into the future, knowing that the comparative
analysis of curricular plans will contribute with findings on the current situation [
        <xref ref-type="bibr" rid="ref6">6</xref>
        ]. The comparison
between faculties of a university in Latvia, indicates that the students of Agricultural Engineering and
Forest Sciences and Forest Engineering have the lowest evaluation of their digital skills; unlike the
specialty Information technologies for sustainable development, a specialty that has the highest [
        <xref ref-type="bibr" rid="ref7">7</xref>
        ].
      </p>
      <p>The objective of this research is to compare the indicators of the dimensions of the digital
competence of the job offers of the companies and the contents of the syllabi of the curricular plan, as
well as the relationship between the academic performance and the level of the indicators of the
dimensions of digital competence in university students.</p>
      <p>
        This study followed a cross-sectional, observational, and analytical study [

      <title>2.1.1. Selection of companies</title>
      <p>The companies were selected from the ranking of the 500 largest companies in Peru 2021 made by
“América Economía” and published in the following link:</p>
      <p>https://www.americaeconomia.com/negocios-industrias/estas-son-las-500-mayores-empresas-delperu-2021, considering as inclusion criteria that they must be based in Arequipa, belong to the value
chain of the sectors or items prioritized in the Arequipa region and training requirements in advertising.</p>
      <p>The search for the job offers of the selected companies was carried out on the Internet, using the
following links:
• Google jobs: https://www.google.com/
• LinkedIn: https://www.linkedin.com/
• Bumeran and other digital job boards: https://www.bumeran.com.pe/</p>

      <title>2.1.3. Application of the survey to students</title>
      <p>For the study, the participation of students enrolled in semesters VI, VIII and X of the even semester
2022 of the University was requested, who after voluntarily accepting the informed consent, completed
a survey via Microsoft Forms which included 03 dimensions, 08 indicators and 47 items (Table 1) with

proven content validation and internal consistency reliability [9]. Each item was measured using a
fivepoint Likert scale, ranging from 1 representing the lowest rating to 5 being the highest.</p>
      <p>The coding matrices were obtained from the qualitative analysis carried out with New NVivo
software. Data analysis was performed with Statistical Package for the Social Sciences (SPSS), version
26. The descriptive measures that were included were: absolute frequency and percentage (%), median
and interquartile range by Me(IQR), Kolmogorov-Smirnov normality test, nonparametric Mann
Whitney U test and Spearman's Rho coefficient. A value of p ≤ 0,05 was considered statistically
significant.</p>

      <title>3. Results</title>
      <p>The results correspond to the study of the job offers of 20 companies, 43 subjects of the 2016 study
plan (07 of General Studies, 04 of Research, 13 of Basic Vocational Training, 17 of Specialty and 02
of pre professional practices) and 185 surveys resolved voluntarily by students of semesters VI, VIII

      <title>3.1. Comparison of the dimensions of digital competence present in the job offers of the companies and syllabus’contents</title>
      <p>The hierarchy of the 20 selected companies was carried out considering the number of items per
indicator of the dimensions of digital competence, according to Ward's link and the re-scaled distance
of 4, finding that they are distributed in 07 clusters, in each of them there are presence of greater
similarity in digital skills that companies request as requirements in job offers. Similarly, the 43 subjects
that record content related to digital dimensions are distributed in 06 clusters. In Table 2, it is observed
that the indicators UTC, R and VAI present the highest averages, that is, they are the skills most required
by companies. SSO and RO have low averages, because it is not common to find them in the job offers
of the companies, and PS has not been found in any of the job offers. These same results were found in
the syllabus’ contents.</p>
      <p>It is important to mention that there is a significant difference (p &lt; 0.05) between the indicators of
the dimensions of digital competence requested by the companies and those found in the syllabi of the
different subjects of the curricular plan studied, except in PS and RO. Table 3 shows the digital skills
that are requested by 100% of the companies studied. As a result of the comparison of the dimensions
of digital competence present in the job offers of companies and syllabus’ content, it is important to
mention:

      <p>Likewise, we observed that the study of the relationship between academic performance and the
level of the indicators of the dimensions of digital competence found a significant minimum direct
correlation [10] (p &lt; 0,05) in the SDO indicator, and a significant low direct correlation in the VAI and
OTV indicators, even though the highest percentage of students present high and very high levels and
89.19% present an academic performance that exceeds 14 as a weighted average.</p>

      <title>4. Discussion</title>
      <p>We are currently witnessing that the digital competence, in people of all ages, has acquired strategic
relevance in the academic and work environment, the success in the development of various activities
depends on the level of competence that people have developed, which has mostly occurred in an
informal environment.</p>
      <p>The fourth industrial revolution is driving a digital transformation that manifests itself as complex
and with interconnection between the different sectors of society, being in turn, a great challenge for
higher education [11].</p>
      <p>In this research, it was found that there is a coincidence in the skills of the job offers requested by
the companies studied, observing that a greater percentage are concentrated in the UTC and IV
indicators of the technological dimension and II of cognitive skills.</p>
      <p>In the curricular plan of the program, depending on the nature of the subject, it is considered in their
content certain skills that, when added together, ensure that graduates have achieved the digital skills
requested as requirements by companies.</p>
      <p>In none of the cases, company or syllabus, is the PS indicator found, even though it integrates skills
that everyone should know at a basic level, to be used immediately and optimize work in the company.</p>

      <p>DIGITAL SKILL
I can use at least one personal computer in terms of hardware (turn
on computer, operate keyboard and mouse, connect devices)
I can use at least one operating system (Windows, OSX, Android,
iOS, others)
I can install and uninstall a program or application
I can use email (create an account, write, and send emails, attach,
and download files)
I can use mobile technology (download applications, register
data/forms, use messaging)
I can use some software programs to visualize data in charts, tables,
graphs, maps, infographics, dashboards, etc.</p>
      <p>I have knowledge of the format and/or extensions that a multimedia
file requires for publication on a channel, application, or digital
platform (video: MPEG4, MP4, AVI. Images: JPG, PNG, GIF)
I can identify key ideas using digital tools (Acrobat, Microsoft Office)
that allow the management of textual information (to highlight,
annotate, draw, etc.)</p>
      <p>Regarding the RO indicator, only 14% of subjects consider it and 10% of companies request it. This
indicator integrates skills that are very important for coexistence in the digital world.</p>
      <p>Our results, related to the job offer, have similarity with those reported by [12] who investigated the
job offer for Marketing professionals finding a percentage of 15.60% in social network management,
followed using Microsoft Office with 14,40%, SEO and SEM positioning with 13,30%, e-mailing with
8,90% and other skills with percentages ranging from 8.30% to 0.60%.</p>
      <p>According to ECLAC (2021), in Latin American and Caribbean countries “…less than 40% of the
population has basic digital skills such as moving information within a document, sending emails,
copying, or moving files. Less than 30% have skills for intermediate activities such as the use of
spreadsheets, management of software for presentations. Less than 25% of the population have more
advanced digital skills such as downloading and installing software and connecting and installing new
devices; and only 7% acknowledge having used a programming language” [13].</p>
      <p>The low correlation found between students' academic performance and their level of digital
competence is since the evaluation instruments measure the contents of the subjects without directly
considering the indicators of digital competence. Our results differ from those obtained in a study by
[14] which concluded that students with higher levels of digital competence obtain better academic
performance in university education.</p>
      <p>However, a report by the Inter-American Development Bank mentions that "Latin America and the
Caribbean have one of the largest skills gaps in the world and talent training systems, including schools,
focus on degrees behind which there are curricula not updated to the new reality. Student performance
is extremely poor compared to other regions” [15].</p>
      <p>In [16] it is mentioned that the technological change that is currently happening has an impact on
the level and composition of labor demand predicting that it will be accentuated soon because most
companies already use digital platforms, cloud computing and the Internet of Things; as well as the use
of Artificial Intelligence, Big Data, Robots, Automation and Cybersecurity that is growing.</p>
      <p>In [17] it is stated that new teaching models are bound to be linked to digital learning methodologies
being important to innovate in the development of virtual learning environments that simulate and
interact with practical learning modalities.</p>
      <p>Similarly, this reality allows us to conclude that although the high and very high level of the
dimensions of digital competence achieved by the highest percentage of students who participated in
our study is in line with the current requirements of the company, it is imminent not only to reformulate
the curricula that already contain training in digital skills, but also to include in those curricula that do
not consider it, so that the University ensures that its graduates can successfully face the technological
innovation that companies will make in the future.</p>
      <p>The scarce existing literature motivates to continue investigating the relationship between academic
performance, level of digital competence in all academic areas and digital competence profile
demanded by the labor market, with the aim of proposing a structure of contents to be included in the
curricular plans, which should be measurable and adaptable to the dynamics of technological
development.</p>
