Data And Information On Data

How to request your personal data from Apple

In the context of higher education, a growing number of schools and universities collect data more info their students with the purpose of assessing or predicting behaviors and academic performance, and the COVIDinduced move to online education dramatically increases what can be accumulated in this way, raising concerns about students' privacy. We focus on academic performance and ask whether predictive performance for a given dataset can be achieved with less privacy-invasive, but more task-specific, data.

We draw on a unique dataset on a large student population containing both highly detailed measures of behavior and personality and high-quality third-party reported individual-level administrative data. We find that models estimated using Data And Information On Data big behavioral data are indeed able to accurately predict academic performance out of sample.

However, models Brandthink only low-dimensional and arguably less privacyinvasive administrative data perform considerably better and, importantly, do not improve when we add the high-resolution, privacy-invasive behavioral data. We argue that combining big behavioral data with "ground truth" administrative registry data can ideally allow the identification of privacy-preserving taskspecific features that can be employed instead of current indiscriminate troves of behavioral data, with better privacy and better prediction resulting. The key premise of learning analytics is that pervasive data collection and analysis allows for informative predictions about academic behavior and outcomes 1although potentially at the cost of student privacy and agency 2as highlighted in recent media coverage 3, 4.

Such concerns have most recently been amplified with the massive shift toward online education following the COVID pandemic 5 6 7. Learning analytics, and, more generally, data analytics, employ as inputs the digital traces that people leave behind when going about their daily business 8searching how will internship you essay internet 9using smartphones 10, 11and engaging on social media Such traces-known also as digital breadcrumbs Data And Information On Data or behavioral surplus 14 -are increasingly valued for their role in predicting behavior both in the market place and in public sector settings, and, increasingly, in higher education. Digital traces of student behavior at the individual level-for example, interaction with digital portals, WiFi use, and locationbased services-can be used to predict key student outcomes such as academic performance and dropout 15 16 However, while such "big data" may have predictive power, the benefits of this come at a potential cost of loss of privacy The privacy-utility tradeoff 18 19 20 posits that predictive ability from personal data is inversely related to privacy preservation.

While generally true within a given dataset, this approach neglects the possibility that other data, possibly from different sources, on the same set of individuals may have a superior predictive ability for a given, or even more favorable, level of privacy. This insight is particularly important for characteristics or behaviors that are more stable over time and for outcomes where past task-specific information is available.

One outcome where information on past task-specific activities is available is school grades: Students in higher education have taken Data And Information On Data examinations prior to college enrollment, and the results of these are highly informative about future performance.

In our sample of engineering college students, using the administrative registry data described below, This suggests the possibility that predicting academic performance may see more require knowledge of sensitive information Data And Information On Data browser use or smartphones, but simply a measure of past performance often used as entry criteria in higher education in the first place. To examine the relative predictive performance of granular "big data" and summary measures of past performance, we combine detailed big data on behavior and personality from the Copenhagen Network Study 11, 21 Keywords Extracted from PMC Text: first- " cross-entry Fig. We use logistic regression methods to classify the students, as these yield the best click Brandthink, but other methods, such as random forest prediction, have similar outcomes.

The terms digital breadcrumbs and behavioral surplus suggest an indiscriminate "big" data collection of identifiable scraps, often collected as by-products of other activities and at low cost, with minimal or no consent, but with potentially large privacy costs per unit of prediction accuracy. In contrast, task-specific data focus on the prediction problem at hand and are, arguably, less privacy invasive than high-granular data.

In order to explore the hypothesis that task-specific data improve prediction, we now distinguish predictive models from two disjointed sets of features: task-specific and general information. Task-specific information contains all measures of historical educational performance middle and high school gradeswhile general information contains everything else, both administrative and big data.

Even with the very rich measurements available regarding individual students, measures of past educational performance are superior predictors for future educational performance. While school outcome trajectories are relatively stable across time, university academic outcomes are well predicted neither from socioeconomic status SES alone nor from adding middle school outcomes.]
