                                               Abstract
                                               The centrality of the right to privacy and personal data protection for high school students is
                                               fundamental in light of the increasing use of digital technologies for educational purposes and
                                               the effort to introduce learning analytics at the school level. The use of digital technologies,
                                               particularly those enhanced by artificial intelligence tools, necessitates heightened attention to
                                               data and privacy law and to the fundamental right to privacy and personal data protection for
                                               high school students, who are inherently vulnerable. All students will be compelled to interact
                                               with school-provided technology, with disabled or socially, culturally, and economically
                                               disadvantaged students being even more vulnerable. The definition of the legal framework in this
                                               domain is a prerequisite for the effective protection of privacy and data and the development of
                                               secure, data-driven technologies. A parallel understanding of the human factors that influence
                                               data handling and privacy is similarly of great consequence. The research project is structured as
                                               follows: (1) outline the legal and ethical rules and principles regarding privacy and personal data
                                               applicable to high school; (2) assess schools' preparedness in managing students' data in
                                               compliance with legal and ethical standards; (3) evaluate teachers' and students' knowledge,
                                               attitude and awareness of privacy and personal data protection, and their behavior during
                                               educational activities in digital environments; (4) outline educational actions and improvement
                                               proposals for managing students' privacy and personal data, especially when learning analytics
                                               will be employed extensively to help optimize learning and improve the environment in which it
                                               takes place.

                                High schools are facing a Copernican shift in how they deliver their educational offerings,
                                forced by technological digital evolution. The new frontier of digital technologies in
                                education, especially those driven by AI and the use of data assets, is the challenge that
                                schools face in order not to be left out of the momentous changes.

Proceedings
    In particular, new digital technologies in education have reflections in the fields of law,
privacy and data protection, learning analytics, and digital literacy. This research project
aims to investigate the issue of privacy and data protection of high school students (age
range 14-18) within the current legal framework in Europe and the use of data in learning
analytics. The European regulatory framework, regarded as the most comprehensive due
to the influence of the GDPR and the EU AI Act, has a great impact.
    Therefore, different fields of study are involved in this set of elements. New digital
technologies in education have implications in the fields of law, ethics, learning analytics,
and digital literacy. In order to understand how to protect privacy and handle data in
accordance with the law and ethical principles, we need to outline the legal provisions on
privacy and data processing, describe the centrality of privacy in the use of digital
technologies in the school environment, and evaluate how privacy impacts learning
analytics and vice-versa. It is of the utmost importance to direct a comparable degree of
attention to the school environment, students' and teachers' activities, awareness,
knowledge, attitude, and behavior on the ground.
    Consequently, it is essential to assess the multiple factors involved in the high school
environment and stakeholders about privacy and data protection, as well as their handling
of personal data.

2. Background
   2.1 Digital Technologies/EdTech
The use of digital technologies in schools is growing steadily and, with appropriate policies,
offers great potential for improving the delivery of education, learning, and school
management.
   Current literature shows that digitization in schools has been in the spotlight during the
recent COVID-19 pandemic, highlighting many problems alongside the promise of
improving the quality of teaching and learning with ICT [1].
   Besides positive results of improving inclusion, participation, and learning, including for
students with disabilities, issues related to the legal compliance of systems and policies, and
stakeholders' competence in terms of the “right to digital literacy” need to be considered
broadly and in-depth [2]. Certainly, for schools that want to keep up and adapt their
educational offer to the canons of digital transformation, the competent use of new digital
technologies, more often supported by AI, will be indispensable.
   The integration of digital technologies into the world of schooling has implications and
effects not only on teaching and learning in the strict sense but also on many interrelated
and equally important issues, including protecting privacy and personal data and managing
students’ data [3]. “Develop a digital citizenship program: as technology use becomes more
prevalent, students must learn about responsible digital conduct. Therefore, schools should
establish a digital citizenship initiative that instructs students on online safety measures,
safeguarding their privacy, and utilizing technology ethically and responsibly” [4] implies
that the consideration has to be extended to teachers and institutions, including the legal
framework and ethical instances [5].
    With the development of digital technologies, research on digital literacy (rectius
literacies) in schools [6] is experiencing considerable ferment from a variety of
perspectives, including data literacy by teachers [7] and annexed study on digital identity
and privacy and training “in favor of conscious use of tools for one’s own virtual identity
and privacy” [8].

   2.2 Privacy and Personal Data
The expansion of digital technologies, particularly in the field of information and
communication technology (ICT), has led to a heightened awareness of the importance of
privacy. This is evidenced by the findings of EDUCAUSE 2020, which identified the
protection of personal data as one of the top 10 IT priorities for the year 2020 (Grajek, 2020)
[9] in the field of higher education, though conceptually generalizable. This is still the case
in the 2023 top 10 IT priorities (Grajek, 2022) [10], where it ranks second.

  Furthermore, this is reflected in the general perception according to the survey on
awareness and management of access to personal data [11].




Figure 2. How did EU people manage access to their personal data in 2023. Retrieved from [11]
    While the majority of research is concentrated on higher education (HE), schools are also
surveyed on a range of related topics, including digital technologies, privacy, ethics, and
data handling. These topics will undoubtedly become more pertinent with the introduction
of AI tools, which will generate insights into the associated privacy concerns and the
question of trustworthiness [12, 13].
    Two key dimensions inform doctoral research on privacy and data protection in schools:
the legal framework at the normative level and the behavioral framework at the concrete
level. The regulatory requirements, their interpretation and application, and the human
factor, as observed in the context of the school environment, represent the two principal
study dimensions of doctoral research. In particular, even if a universal definition of privacy
is lacking [14] for some, legal certainty is essential to provide the ground rules. In addition,
a more detailed examination of regulation should encompass the applicability of the
"procedural account of technology-neutral regulation" in the context of education. This
would entail the creation of legal frameworks that can accommodate future technological
developments without necessitating the implementation of specific adjustments for each
new technology [15].
    A multidisciplinary approach, drawing on the expertise of legal and learning sciences,
will enable the most comprehensive definition of the current state of the art in privacy and
data handling, as well as the development of robust proposals [16]. In light of these
considerations, it becomes evident that grasping the ratio between rules and behavior is of
paramount importance. In the specific case of privacy, a fundamental question has been
raised: do people really care about their privacy? [17]. A 2023 survey with 2,600 of 18 years
and older from the following countries: Australia, Brazil, China, France, Germany, India,
Italy, Japan, Mexico, Spain, United Kingdom, and the United States gave evidence that on
average, 46 percent of respondents across all surveyed countries were aware of their local
privacy laws, with peaks of 63 percent from India, 63 percent from the UK and 55 percent
from Italy. But on this same issue, we need to compare this evidence with the "privacy
paradox" issue. This concept highlights the inconsistency of privacy attitudes and behaviors
in the face of the assumption that people care about their privacy [18]. Thus, attitude and
behavior must be evaluated with caution, and awareness becomes a key factor.
    This is a groundbreaking topic for high school students who are going through the
process of developing character and building knowledge.
    However, in dealing with awareness, educational stakeholders involved in data
management must possess a comprehensive and preliminary understanding of privacy
principles anchored in explicit legal frameworks.

 YEAR             EVENT
 1950             Article 8 of the European Convention on Human Rights (ECHR), which
                  establishes the right to respect for private life
 1981             The Council of Europe adopts Convention 108- now Convenction 108
                  Plus – which is the largest European -level document for the protection
                  of personal data
 1995             The EU adopts Directive 46/95 on the protection of personal data
 2001             Approval of the Nice Charter, in which Article 8 establishes the right to
                  protection of personal data
 2007             The right to the protecion of personal data enjoyed by every person was
                  reaffirmed in the TFEU. In addition, the legislative competence of the
                  European Parliament and the Council on the subject was established.
 2016             General Data Protection Regulation (GDPR)
 2024             The Council of the European Union approves of the EU Artificial
                  Intelligence ACT.

   Accordingly, a legal definition of privacy and data protection requires an understanding
of the intertwined provisions of multiple regulatory sources, including the General Data
Protection Regulation (GDPR) and the recently enacted EU Act on Artificial Intelligence (AI).
Although the latter is the most widely recognized regulatory source, it is crucial to
acknowledge that it is not the sole relevant regulatory instrument.
   A comprehensive understanding of the full range of regulatory frameworks will enable
each stakeholder to fulfill their obligations with confidence and a heightened sense of
responsibility, thereby facilitating informed decision-making with regard to the handling of
data.

   2.3 Learning analytics
   One of the best-known definitions of learning analytics (LA) is from Siemens (2013) [20]
who states that "Learning Analytics is the measurement, collection, analysis, and reporting
of data about learners and their context to understand and optimize learning and the
environment in which it takes place" (p. 1382).
   The importance of data analytics in education is a multi-level issue: data-based decision-
making, monitoring and evaluating processes for administrators; helping self-regulation in
the online environment; supporting quality, effectiveness, and assessment of teaching and
learning activities outcomes for teachers and students [21]. The potential benefits of LA at
the high school educational level are highlighted by the current Quality Assurance with
Learning Analytics in Schools (QUALAS) project (01/10/2023-30/09/2026), which aims to
build capacity in secondary education schools for the use of learning analytics in the
framework of quality assurance [22].
   Ethical and legal issues related to privacy and data processing in education are a topic of
general interest [23]. They have been a recurring and hot topic of discussion in the LA
community because of their close connection to data processing.
   In general, research on effective privacy-enhancing practices in LA tends to focus on
specific aspects, such as students' privacy concerns, perceptions of privacy risk and control,
trust, and willingness to share personal data. Understanding students’ privacy concerns is
seen as an essential first move toward “effective privacy-enhancing practices” in LA [24].
   When designing an LA system for high schools, it is essential to consider beforehand the
interests of all stakeholders. Research has primarily focused on the higher education level,
and further investigation is needed to understand the conditions under which high school
students are willing to disclose data relevant to learning analytics systems [25, 26].
   Models have been developed to explore students' privacy concerns, from the APCO
(Antecedents → Privacy Concerns → Outcomes) to SPICE (students' privacy concerns),
focusing on the antecedents-to-privacy-concerns link. Similar models for high school
students must take into account various factors, from those of knowledge to those of
awareness, confidence, attitude, and relationship with teachers, better in the midst of
learning when data are generated.
   As observed in a recent review on human-centred learning analytics and AI in education
data, despite privacy emerging as a much-discussed topic, gaps remain in our
understanding of the importance of human control, safety, reliability, and trust in designing
and deploying these systems [27]. What emerges is a resolution to define the parameters
within which to operate legally and ethically, and to provide practical and compliant ways
of doing so [28]. Students must be considered agents of their own learning and any LA
system must be a student-centered learning analytics (SCLA) [29]. In this scenario, the
agency of students (and teachers) must be strengthened by effective legal competence of
their rights and protections, because the undefined concepts are the enemy of their respect.
   In light of this, it is advisable to broaden the scope of the inquiry to understand the
factors that may affect data privacy at the high school level, with particular attention to the
human elements at play, namely the behavior, attitude, legal knowledge, and literacy, and
expectations of students and teachers, as well as their interrelation.
   The use of LA in high schools, which is likely to increase, must be designed with an
awareness of the range of human factors that can affect the proper handling of data. Not
neglecting the need to comply with the kind of regulatory strategy that will be outlined for
privacy and data protection in the face of the more futuristic stresses of technology
development (namely AI-driven).

3. Goal and research questions
    When considering privacy and data protection in the context of upper secondary
education, it is essential to take into account the legal framework for privacy and data
processing, both in general and specifically.
    This begins with an analysis of the regulations in question and their application by
judicial bodies. This is particularly important in light of recent regulatory interventions, i.e.
the EU AI Act, that apply directly in Europe and may apply indirectly elsewhere.
Subsequently, we need to understand whether educational institutions, namely high
schools, and their employees (primarily teachers) are actually behaving in accordance with
the rules. In this way, it is possible to weigh up which elements have the greatest impact on
the issue of privacy and data protection.
    It is equally important to understand that the protection of privacy and the management
of personal data in the school context are influenced by different variables that emerge from
the environment (e.g. ICT structures and systems, legal documents and prescription), the
behavior (conduct), and the subjective sphere of individuals (i.e. awareness, knowledge,
expectations, trust) that can only be assessed through a field study and subsequent analysis
of the data collected. Finally, based on the quantity and quality of the data collected and the
results obtained from their interpretation, it is possible to provide operational indications
to educational institutions and recommend training courses for teachers and students to
make the protection of privacy and personal data as effectively as possible and to propose
operational paradigms to the LA in the management of high school student data.
   Accordingly, the research questions for this project may be formulated as follows:
   RQ1: What are the legal definitions of privacy and personal data within the relevant legal
framework, and what effects do they have on school activities?
   RQ2: How do high schools concretely manage data and protect privacy, and what are the
behaviors, knowledge, awareness levels, and potential risks and causes associated with the
activities of teachers and students?
   RQ3: How can the protection of students' privacy and personal data be made more
effective, and what operational proposals can be formulated?

4. Methods
   To answer the research questions of the PhD project, the work is divided into three
phases. The first consists of a systematic scoping review in the law domain, learning
analytics, privacy and data, digital technologies, and high school.
   Furthermore, I will also conduct a review of current research in the learning analytics
domain to assess the methods and objectives used to discuss and manage privacy
awareness and knowledge in high school context. Strings containing a combination of the
keywords "Privacy, Privacy awareness, and knowledge, Data & Privacy Law, Digital
technologies, High School Students, Learning analytics, Data Literacy" are entered to query
the Scopus Web of Science, Eric, and Bera databases. Relevant official documents and
publications are retrieved from institutional sites (inter alia OECD, UNESCO, EUR-lex). The
review will be based on PRISMA-ScR checklist and explanation and the JBI methodological
guidance [30]. Thus, the results will help the evaluation of privacy concerns, awareness,
knowledge, attitude, and behavior in the education environment [31].
   The second phase is focused on collecting and analyzing data. Survey research will likely
be employed to collect data and to ascertain specific characteristics of the group in question
(Fraenkel et al.) [32]. Survey studies offer a quantitative description of trends, attitudes, and
views across a population through studies conducted on a representative sample.
Therefore, an explanatory sequential design will start with a structured questionnaire for
students and teachers comprising multiple-choice questions on a Likert scale (still to be
defined) to ascertain the value of students' and teachers' awareness, knowledge, behavior,
trustworthiness and attitude regarding the high school privacy law and ethics in data
management. Qualitative data collection and analysis through focused interviews will
enhance the comprehension of the underlying reasons behind statistical findings [33, 34].
   Finally to enrich the body of knowledge that will emerge from the research and to make
the connection to the LA more consistent, I am considering whether it would be feasible to
include in the research project the idea of simulating the use of the LA within high schools
for student assessment and school self-assessment.
   Approval from the university's ethics committee and permission from the school
principals will be required.
  The third phase is the analysis, study, interpretation and systematization of data for the
development of possible proposals and guidelines for practitioners.

5. Current status of the work
A scoping review of the literature relevant to the following major research topics is under
review: (1) the legal framework, (2) digital technologies in education (3) privacy and data
protection in high school, and (4) learning analytics, ethics and privacy issues. Updating and
systematization of the literature review records are underway.
   In addition, in the coming months of the year, with the support of statistical experts, the
identification and development of survey instruments to be used in high schools as soon as
activities resume, i.e. in September 2024, will be carried out.
   Finally, I am reflecting on the methods, time, and means of implementing an LA driven
experiment in the school.

6. Contribution
The project's contribution falls under the broad LA theme of "Ethics, Privacy, Regulations
and Policies." In particular, the first contribution will be to systematically define the law
concepts of privacy rights and personal data protection in the high school context and
within the use of digital technologies, with the clarity of timely and explicit reference to the
regulatory framework, primarily European (e.g., GDPR, AI ACT).
   The second contribution will entail observing and evaluating the management of privacy
and the handling of personal data in digital environments by high school students and
teachers. This will enable the measurement and evaluation of the impact of various factors
affecting data handling and privacy in real-world educational contexts.
    The third contribution will be to propose practical and targeted strategies to enhance
the digital and legal literacy of students and teachers. Additionally, it will formulate
practical preparatory guidance for learning analytics that is responsive to privacy and data
safety at the school level, once it becomes fully widespread.
