Using Electronic Materials in the EFL Classroom: 8th Graders’ Views on the Motivational Aspect of E-materials
2018
Uusien opetussuunnitelmien ja teknologian edistymisen myötä sähköisten oppimateriaalien rooli eri luokka-asteilla alakoulusta lukioon on kasvanut melko keskeiseksi. Kyseisiä materiaaleja hyödyntämällä päästään lähemmäksi paitsi perusopetuksen myös lukion opetussuunnitelmaan kirjattuja tavoitteita, joiden mukaan oppilaiden ja opiskelijoiden tulisi muun muassa harjoittaa tieto- ja viestintäteknisiä taitojaan muun oppimisen ohella oppiaineessa kuin oppiaineessa. Aikaisempaa tutkimusta aiheesta on tehty vielä melko vähänlaisesti, ja toisaalta olemassaolevat tutkimukset ovat pääasiallisesti keskittyneet opettajien mielipiteisiin ja näkemyksiin sähköisten materiaalien käytöstä oppitunneilla.

Training machine learning models with synthetic data improves the prediction of ventricular origin in outflow tract ventricular arrhythmias
2022
In order to determine the site of origin (SOO) in outflow tract ventricular arrhythmias (OTVAs) before an ablation procedure, several algorithms based on manual identification of electrocardiogram (ECG) features, have been developed. However, the reported accuracy decreases when tested with different datasets. Machine learning algorithms can automatize the process and improve generalization, but their performance is hampered by the lack of large enough OTVA databases. We propose the use of detailed electrophysiological simulations of OTVAs to train a machine learning classification model to predict the ventricular origin of the SOO of ectopic beats. We generated a synthetic database of 12-l…
Absolute of Relative? A New Approach to Building Feature Vectors For Emotion Tracking In Music
2013
It is believed that violation of or conformity to expectancy when listening to music is one of the main sources of musical emotion. To address this, we test a new way of building feature vectors and representing features within the vector for the machine learning approach to continuous emotion tracking systems. Instead of looking at the absolute values for specific features, we concentrate on the average value of that feature across the whole song and the difference between that and the absolute value for a particular sample. To test this “relative” representation, we used a corpus of popular music with continuous labels on the arousalvalence space. The model consists of a Support Vector Re…

A case study of a British ERASMUS student in Italy
2013
This article focuses on the shaping of social identities and emotions of one British young woman who spent a Year Abroad (YA) in Italy as an ERASMUS student. I have examined her negotiation and (re)construction of social identities during her experience abroad from a poststructuralist perspective, which sees individuals’ identities as dynamic and changeable sites of struggles (Norton Pierce, 1995 and 2000). In order to analyse the participant's accounts of her language learning and emotional experiences during her YA I have used the notion of emotional investment developed by Pavlenko (2012). This notion has helped me to understand how, why and to what extent the participant in the study ga…
Classification of Solutions to the Minimum Energy Problem in One Dimensional Sensor Networks
2016
We classify of the minimum energy problem in one dimensional wireless sensor networks for the data transmission cost matrix which is a power function of the distance between transmitter and receiver with any real exponent. We show, how these solutions can be utilized to solve the minimum energy problem for the data transmission cost matrix which is a linear combination of two power functions. We define the minimum energy problem in terms of the sensors signal power, transmission time and capacities of transmission channels. We prove, that for the point-to-point data transmission method utilized by the sensors in the physical layer, when the transmitter adjust the power of its radio signal t…
Valodas mācīšanās paņēmieni sākumskolas skolēniem ar dažādiem mācīšanās traucējumiem angļu valodas mācīšanās veicināšanai
2020
Diplomdarba pētījums tika veikts, lai labāk izprastu iekļaujošās izglītības idejas praktisko pielietojumu situācijās, kad angļu valodas skolotājam jāstrādā arī ar skolēniem, kuriem ir mācīšanās traucējumu pazīmes. Diplomdarba mērķis bija noskaidrot, kādi valodas mācīšanās paņēmieni var palīdzēt sākumskolas skolēniem ar dažādiem mācīšanās traucējumiem angļu valodas mācīšanās veicināšanai. Par pētījuma metodi tika izvēlēts gadījuma pētījums. Respondentu izlasē tika iekļauti 15 angļu valodas skolotāji no dažādām vispārizglītojošajām skolām un 14 sākumskolas posma skolēni vecumā no 7 līdz 9 gadiem vienā no Rīgas privātajām vidusskolām. Kā datu ieguves metode skolotāju viedokļa noskaidrošanai ti…
Secondary Education Students’ Questions on Experimental Devices
2012
Las preguntas forman parte esencial del trabajo que desarrollan los científicos para construir nuevo conocimiento. Sin embargo, los alumnos formulan un número muy escaso de preguntas en las situaciones usuales de aula. En este trabajo se realiza una revisión de las investigaciones realizadas sobre génesis de preguntas y se describen tres estudios empíricos realizados con estudiantes de diferentes niveles educativos ante dispositivos experimentales. Los objetivos fueron: 1) Estimular y analizar las preguntas de los estudiantes cuando intentan comprender los dispositivos; 2) Contrastar la idea de que la mayoría de preguntas destinadas a obtener información tienen su origen en inferencias fall…
Multimodal Communication and Peer Interaction during Equation-Solving Sessions with and without Tangible Technologies
2023
Despite the increasing use of technologies in the classroom, there are concerns that technology-enhanced learning environments may hinder students’ communication and interaction. In this study, we investigated how tangible technologies can enhance students’ multimodal communication and interaction during equation-solving pair work compared to working without such technologies. A tangible app for learning equation solving was developed and tested in fourth and fifth-grade classrooms with two class teachers and 24 students. Video data of the interventions were analysed using deductive and inductive content analysis. Coded data were also quantified for quantitative analysis. Additionally, teac…
