1. INTRODUCTION

By allowing the extraction of useful insights from huge amountsofdata,dataminingtechniqueshavetransformeda number of industries. The wealth of data produced by collegestudents,academicstaff,andeducationalinstitutions offersasingularopportunitytousedataminingtechniques to enhance teaching methods, student results, and institutionaleffectiveness.Thisintroductiongivesageneral overviewofdataminingmethods,ideas,andtheparticular uses to which they might be put in the context of higher education [1]. Data mining, commonly referred to as knowledge discovery in databases (KDD), is a group of computational methods and algorithms used to glean patterns,connections,andhiddeninformationfromsizable datasets. Utilizing statistical, mathematical, and machine learning techniques, it entails the extraction of pertinent

information from unstructured data. Generally speaking, therearetwobasiccategoriesfordataminingtechniques: descriptiveandpredictive.Themaingoalofdescriptivedata mining techniques is to summarize and visualize data in ordertoidentifypatternsandtrends.Amongthesemethods are clustering, which compiles related data objects, and association rule mining, which reveals dependencies and connectionsbetweenvariousdataproperties[2].

While developing models that can classify or make predictionsbasedonhistoricaldata,predictivedatamining techniquestrytodotheopposite.Tocategorizeorclassify dataexamples,classificationmethodslikedecisiontreesand supportvectormachinesareused.Additionally,regression analysiscanbeusedtoanticipatecontinuousvariablesand timeseriesanalysistoforecastfuturetrendswhencreating predictive models. Techniques for extracting knowledge from various educational data sources have proven to be useful in the field of higher education [3]. Student informationsystems,learningmanagementsystems,online resources,socialmedia,andresearchdatabasesaresomeof thesesources.Educationalinstitutionscanlearnmoreabout the behavior of their students as well as their learning habits, academic achievement, and engagement by evaluatingthisdata.Dataminingisusedinhighereducation in a variety of ways. Student performance analysis is one importantareawheredataminingtechniquescanbeusedto pinpoint variables that affect students' achievement, spot warningsignalsofacademic problemsearlyon,andtailor interventionstohelpstrugglingstudents.Dataminingcan alsoaidinthecreationofsystemsthathelpstudentschoose courses that are in line with their interests, academic objectives,andperformancehistories[4].

Additionally,dataminingtoolsallowfortheforecastingof student dropout rates, allowing institutions to take preventative action to reduce attrition. Institutions can identify students who are at danger of dropping out by examiningpreviousdatapatternsandcanthenofferthem targetedsupporttoincreasetheirretentionandgraduation rates.Furthermore,data mining canhelp withcurriculum design optimization by identifying course prerequisites, relationships between courses, and areas for curriculum enhancement based on pupil performance and feedback.

Dataminingapplicationsinhighereducationdo,however, present some problems and ethical questions. Important issuesthatneedtobeaddressedincludeprivacyprotection, data security, and the proper use of information that has been mined. In order to protect individual privacy, institutionsmustmakesurethatstudentconfidentialityis upheldandthatdataissuitablyanonymizedandaggregated [5].
