Historical Background

The development of big data in education has a long history, extending beyond the widespread recognition it gained in the 21st century. The inception of large-scale data collection in education can be traced back to ancient times. Early Sumerian societies around 3200 B.C. conducted censuses to allocate resources and plan for infrastructure such as levees and canals, which included data relevant to educational planning[1]. Modern countries continued this tradition, with many embedding census-taking into their foundational government documents, including the United States, Australia, and most of the European Union[1]. By the 1990s, both developed and developing nations, such as China and India, began systematically collecting and publishing educational data as part of their broader census efforts[1].

In recent history, significant policy reforms in the UK have further advanced the use of big data in education. The Data Futures program, initiated in response to the 2011 white paper “Students at the Heart of the System” by the Department of Business, Innovation and Skills (BIS), exemplifies this evolution[2]. This initiative was part of a long-term government reform agenda later outlined in the 2016 white paper “Success as a Knowledge Economy,” aiming to enhance student choice, create a competitive marketplace of higher education providers, and improve educational outcomes[2].

The reformatory recommendations included making students in England pay full fees for degree courses and establishing the Teaching Excellence Framework (TEF) to assess and rank university teaching quality[2]. The infrastructure for data collection has evolved incrementally, adapting to new technological, organizational, and political changes. According to Bowker and Star (2000), infrastructure development is a gradual process involving continuous negotiation and adaptation[2]. This dynamic evolution is evident in the complex ecologies of fully developed infrastructures, which must constantly adapt to ongoing changes in their components[2]. The emergence of new ideas, technologies, and regulatory frameworks, along with shifts in the political economy and market dynamics, continuously reshapes these infrastructural assemblages[2].

In this context, the control over data has shifted significantly from state monopolies to a more fragmented landscape involving various corporations, agencies, and organizations. This shift has resulted in the production of granular, immediate, and detailed data about educational subjects and objects, far beyond what any state or organization has historically managed[2]. Consequently, data has become a critical object of interest for those in power, further underscoring its importance in contemporary educational reform and practice[2].

Key Components

Context- or Need-Driven Analytics Approach

The context- or need-driven analytics approach in big data education emphasizes the importance of understanding the different modalities for managing educational data effectively. This approach involves converting context knowledge into actionable intelligence through various analytics and data processing techniques [3]. For example, descriptive analytics generates reports and summaries to answer questions such as “What is happening now?” by monitoring processes in real-time and providing alerts. Predictive analytics, on the other hand, uses past actions to estimate future out- comes, identify trends, and simulate alternative actions to support decision-making [3].

Learning Analytics

Learning Analytics (LA) is defined as the measurement, collection, analysis, and reporting of data about learners and their contexts to optimize learning and the environments where it occurs [3]. LA helps detect behavioral patterns, such as user satisfaction, and anomalies, like cheating. By analyzing past events, LA engines can predict future outcomes and suggest different decision options, revealing the implications of each choice. Enhanced with visual tools, LA amplifies insights, increases understanding, and impacts decision-making [3].

Challenges

Infrastructure Complexity

The deployment and maintenance of big data infrastructures in education present significant challenges. Infrastructures are complex and require considerable effort to build, maintain, repair, and sustain [2]. They are not merely neutral backdrops but rather heterogeneous assemblages of technological objects, standards, values, administrative procedures, and organizational work [2]. These infrastructures involve a myriad of people, institutions, technologies, policies, legalities, and financial arrangements, all interwoven to ensure functionality [2]. The necessity of creating networked gateways or sockets between heterogeneous systems adds to this complexity, as these changes take time, negotiation, and adjustments with other system components [2]. Fully developed infrastructures thus represent complex ecologies where components must continually adapt to each other’s ongoing changes [2].

Standardization of Data

One of the pivotal challenges in big data in education is the standardization of data. Data standards are crucial for any large-scale information infrastructure, providing benchmarks for data quality and defining how information is formatted and categorized [2]. These standards are not static; they evolve and mutate as new ideas and knowledge emerge, technologies are invented, organizations change, and various external factors shift [2]. Therefore, the development and maintenance of standards are complex political and philosophical problems, as they underpin the potential for action in both political and scientific spheres [2]. The alignment of different standards across various institutions and technologies remains a significant challenge.

These issues mirror the ethical challenges encountered in the health sector, where large datasets are similarly utilized for secondary purposes[17].

Transparency and Consent

Higher education participants underscored the importance of individual consent, viewing failures in transparency as failures to achieve such consent[11]. They argued that students must be informed about how their data is used to make informed decisions about sharing information. The broad consent typically provided upon enrollment is often deemed insufficient, and there is a call for heightened student awareness both at the beginning and throughout their educational journey. However, individual consent for every use of student data is recognized as impractical, leading to the dilemma of balancing broad consent with ongoing transparency efforts[11]. Contrastingly, health sector participants generally considered individual consent for big data use unnecessary due to the impracticality of seeking consent from large numbers of individuals. Instead, they emphasized the need for public information about data use and robust legislative oversight. This divergence in approach high- lights the sector-specific challenges in managing consent and transparency[11].

Privacy and Confidentiality

Participants from both sectors expressed concerns about privacy and confidentiality, often framing these issues in terms of traditional research ethics. The sheer scale of big data and the waiver of consent in many cases complicate ensuring that participants understand their information is being used for secondary purposes[11][18]. There are calls for updated legislative frameworks to keep pace with technological advancements and protect individual privacy adequately[18].
