Students' Perceptions on Engaging Database Domains and Structures
2023
Several educational studies have argued for the contextualization of assignments, i.e., for providing a context or a story instead of an abstract or symbolic problem statement. Such contextualization may have beneficial effects such as higher student engagement and lower dropout rates. In the domain of database education, textbooks and educators typically provide an example database for context. These are then used to introduce key concepts related to database design, and to illustrate querying. However, it remains unstudied what kinds of database contexts are engaging for novices. In this paper, we study which aspects of database domain and complexity students find engaging through student…

Digital Education For All: Multi-University Study of Increasing Competent Student Admissions at Scale
2022
An indubitable way to put learning at scale in practice is to implement Massive Open Online Courses, or MOOCs. When a wide-enough portfolio of them is available, new applications arise. For instance, university admissions in Finland, where this study was conducted, have traditionally been based on students' grades in high school studies, an entrance examination, or a combination of both. A minority of students have been accepted through an open university admission path where students can get a study right if they complete enough university course credits with a high enough grade in a given time frame. In this work, we report results from a multi-university project in which the open univers…
On the impact of computer science outreach events on K-12 students
2016
Many countries have begun to adopt computer science (CS) and computational thinking (CT) into national curricula of compulsory education and upper secondary education. It is argued that learning rigorous CS concepts not only secures a workforce for the future’s digital industries but also benefits all students by improving their problem-solving and logical reasoning skills. However, the popularity of CS as a university major declined in the beginning of the 21st century, resulting in the development of a range of student outreach activities to engage young students in the study of computing. This thesis originated from this need to attract and retain students in the CS field. The focus of thi…
A bibliometric approach to finding fields that co-evolved with information technology
2020
Among the declining industries, for example music industry, some have been revived by information technology (IT). At the same time, in academic fields, some have expected co-evolutions between IT and other fields to cause the resurgence of either field. In this research, the clustering of citation networks with 14,438 academic papers resulted in the identification of 28 academic fields in the areas “Computer Science” or “Information Science and Library Science.” Co-evolutions between these 28 fields and citing fields to the 28 fields were evaluated by an investigation of contents; a methodology to search co-evolutions was also proposed. This paper proposes that pairs of academic fields (wi…
Knowledge mining using robust clustering
2006
FM Sami Äyrämö tutki väitöstyössään suurten digitaalisten tietomassojen tehokasta hyödyntämistä ja siihen sovellettavia laskennallisesti älykkäitä niin kutsuttuja tiedonlouhintamenetelmiä (data mining). Aihe on ajankohtainen, sillä informaatiojärjestelmien nopea kehittyminen ja yleistyminen johtavat entistä useammin ”datatulvaan": digitaalisessa muodossa kerätään tietoa niin paljon, että oleellinen informaatio voi hukkua epäoleellisen ja moninkertaisen tiedon sekaan.Väitöstyönsä päätuloksena Äyrämö esittelee luotettavan, laskennallisesti tehokkaan ja käyttäjälle yksinkertaisen klusterointimenetelmän, joka ei ota kantaa sovelluskohteeseen ja on siten hyvin yleiskäyttöinen. Menetelmän pohjana…
