Online anomaly detection using dimensionality reduction techniques for HTTP log analysis
2015
Modern web services face an increasing number of new threats. Logs are collected from almost all web servers, and for this reason analyzing them is beneficial when trying to prevent intrusions. Intrusive behavior often differs from the normal web traffic. This paper proposes a framework to find abnormal behavior from these logs. We compare random projection, principal component analysis and diffusion map for anomaly detection. In addition, the framework has online capabilities. The first two methods have intuitive extensions while diffusion map uses the Nyström extension. This fast out-of-sample extension enables real-time analysis of web server traffic. The framework is demonstrated using …
Listwise Collaborative Filtering
2015
Recently, ranking-oriented collaborative filtering (CF) algorithms have achieved great success in recommender systems. They obtained state-of-the-art performances by estimating a preference ranking of items for each user rather than estimating the absolute ratings on unrated items (as conventional rating-oriented CF algorithms do). In this paper, we propose a new ranking-oriented CF algorithm, called ListCF. Following the memory-based CF framework, ListCF directly predicts a total order of items for each user based on similar users' probability distributions over permutations of the items, and thus differs from previous ranking-oriented memory-based CF algorithms that focus on predicting th…
Does the Learning Channel Really Matter? - Insights from Commercial Online ICT-training
2017
Evolving ICT has provided new options to participate to training. Online participation has been found to be cost effective, helping people to deal with the time and cost pressures they are facing on their jobs. Previous studies conducted in higher education sector indicates that student satisfaction or learning outcomes does not differ between online and classroom participants. However, little is known what is the situation in commercial ICT-training. This paper studied course feedbacks from courses having both online and classroom participants of a commercial ICT-training provider. Results revealed that the learning channel has no effect on satisfaction, perceived teacher’s substance and t…
Bridging authentic learning task into technology supported transformative pedagogy in Finnish teacher training
2018
The goal of the Finnish teacher training is to educate autonomous teachers, who have pedagogical competence and theoretical understanding about using ICT in teaching and learning. In this study, we describe teacher students’ pedagogical ICT competence as designers of technology supported learning tasks. The study is based on Hughes’ RAT model, which is a framework for assessing technology integration. The theoretical definition of RAT model is technology as a) replacement, b) amplification or c) transformation. To define this there are three systematical dimensions to analyze a particular technology use: Instructional Methods, Student learning processes and Curriculum Goals. The data consis…
Growth Into Citizenship: Framework for Conceptualizing Learning in NGO Interventions in Sub-Saharan Africa
2018
This article develops a theoretical framework for analyzing adult learning in projects aiming to strengthen citizenship implemented by nongovernmental organizations, especially in the contexts of sub-Saharan Africa. On the basis of a review of international development research, we suggest that a new framework should address the need for a conceptualization of learning as a gradual process and for capturing the gap between ideal models and everyday experiences of citizenship. We argue, building on John Dewey’s philosophy, for a framework of growth into citizenship, and introduce the notions of learning as reorganization of habits and the method of democracy as an avenue for learning as nove…

Creating a collaborative ESL classroom through teacher leadership : a case study in Guizhou Province, China
2016
This research looks into collaborative learning with teacher leadership in the ESL classroom of Guizhou, China. The phenomenon, purpose, research methods, main results and conclusions of the study are provided in the abstract. Under the phenomenon of New High School Curriculum Reform Program in China in 2004, all Chinese schools are trying new teaching methods to improve students’ English level. The purpose of the study is getting a better understanding of collaborative learning with teacher leadership in the ESL classroom. Qualitative research is applied to collect the data from the Chinese school. The research data is collected through two questionnaire surveys (open-ended questionnaires)…
Teaching foreign language to the elderly : teachers perceptions
2009
Väestön ikääntymisen myötä eläkeikäisten ihmisten rooli on noussut tärkeään asemaan myös vieraiden kielten oppimisessa ja opetuksessa. Ikääntyneitä oppijoita on kuitenkin tutkittu Suomessa vielä valitettavan vähän. Poikkeuksena mainittakoon Aino Jaatisen (2003) paljolti omaksi avukseen laatima tutkimus ikääntyneistä englannin oppijoista, jota on käytetty pohjakirjallisuutena myös tässä tutkielmassa. Tämän proseminaarityön päämääränä on ollut kartoittaa vieraiden kielten opettajien havaintoja iäkkäistä oppijoista sekä heidän mahdollisesti käyttämiä opetusmetodejaan. Tutkimusaineisto kerättiin kyselylomakkeen avulla, johon vastasi kuusi opettajaa. Tutkimustulokset osoittivat, että opettajat …
Motivational strategies used by English teachers : students’ opinions
2017
Se, miten motivoituneita ihmiset ovat tekemään asioita elämässään, vaikuttaa suuresti heidän saavutuksiinsa. Motivaatiolla on myös huomattava yhteys menestymiseen vieraiden kielten opiskelussa. Motivaation vaikutusta vieraiden kielten opiskeluun on tutkittu laajasti, mutta opiskelijoiden mielipidettä opettajien käyttämiin motivointikeinoihin ei ole juuri tutkittu Suomessa. Tässä tutkimuksessa selvitettiin lukion ensimmäisen luokan opiskelijoiden mielipiteitä motivointikeinoista, joita englannin opettajat voisivat käyttää opetuksessaan. Opiskelijat täyttivät kyselylomakkeen, jossa heidän tuli valita Zoltán Dörnyein opettajan käyttämien motivointikeinojen listasta neljä eniten motivoivaa ja n…
It’s Not Only What You Say, But How You Say It : Investigating the Potential of Prosodic Analysis as a Method to Study Teacher’s Talk
2018
In this study, we introduce new insights into prosodic analyses as an emerging method to study what happens in classrooms interactions. We claim that the prosodic aspects (features of speech such as intonation, volume and pace) of talk are important, but under-represented in the learning sciences. These prosodic aspects may be used to complement, intensify or even reverse the linguistic content of speech. Thus far, most research on classrooms has focused on the content (what is said) rather than on understanding the meaning of the prosodic features (how it is said) of talk. In this study, we introduce prosodic analyses as a method to study classroom discussions. Our exploratory experiment f…
