- W3204998518 abstract "Learning analytics is used to measure, collect and analyse educational data. It extracts valuable information from educational data of students for the purpose of understanding and optimizing educational practices. It helps in developing predictive models using past educational data of students to improve future practices. It benefits stakeholders to improve learning processes by providing timely feedback regarding their progress. Although sharing and using of data include privacy risks for data subjects, privacy is the right of individuals to secure his/her personal information. Data privacy is a concern of sharing the data with a third party. The k-anonymization is the most popular existing privacy technique which helps to resolve privacy issues, but it also has some drawbacks. It leads to loss of information that is dependent on the value of k parameter. This paper discusses in detail about learning analytic, need for privacy in learning analytics, existing privacy preservation techniques and various existing privacy issues in learning analytics. An exhaustive literature survey has been done, and comparison between various existing privacy techniques has been presented." @default.
