LightSleepNet: A Lightweight Deep Model for Rapid Sleep Stage Classification with Spectrograms.
2021
Deep learning has achieved unprecedented success in sleep stage classification tasks, which starts to pave the way for potential real-world applications. However, due to its enormous size, deployment of deep neural networks is hindered by high cost at various aspects, such as computation power, storage, network bandwidth, power consumption, and hardware complexity. For further practical applications (e.g., wearable sleep monitoring devices), there is a need for simple and compact models. In this paper, we propose a lightweight model, namely LightSleepNet, for rapid sleep stage classification based on spectrograms. Our model is assembled by a much fewer number of model parameters compared to…
The use of technological devices in English teaching as experienced by teachers
2017
Teknologiaa on käytetty osana opetusta jo vuosikymmenten ajan. Tekniikan kehitys ja saatavuus ovat kuitenkin muuttuneet laajalti vuosien aikana. Nykyään sekä koulun tarjoamat, että oppilaiden omat laitteet ovat vahvasti läsnä kielten opetuksessa. Laitteiden kirjo on moninaistunut uusien laitteiden myötä. Luokassa saattaa olla hyvin laaja kirjo erilaisia laitteita, joita opettaja voi hyödyntää osana opetustaan. Tutkimuksen tarkoituksena on selvittää tämän hetkistä tilannetta englannin opetuksessa yläkoulussa ja lukiossa. Tutkimus kartoittaa, minkälaisia laitteita opetuksessa käytetään, ja miksi. Lisäksi pyritään selvittämään millaisia hyötyjä ja haittoja teknologian käytöstä on vieraiden kie…
Designing and investigating pedagogical scripts to facilitate computer-supported collaborative learning
2008
Computer-supported collaborative learning (CSCL) appears to provide a promising social approach to foster learning. On the other hand, recent studies have indicated that when learners are left on their own, it is often difficult for teams to engage in productive interactions. Therefore, the use of collaboration scripts as instructional support has been presented as a possibility to trigger productive collaborative activities. This study provides knowledge of collaboration scripts as a pedagogical method to facilitate group processes in virtual environments in authentic educational contexts. The findings indicate that scripts as external support can help students proceed in solving learning …
Case-based portraits of contrasting micro-interaction processes during online assessment of collaborative problem solving
2017
This study recognizes the role and the quality of social aspects in collaborative problem solving (CPS) processes and outcomes. The aim of this study, relying on multiple data and phases of analysis, is to explore and visualise, through contrasting case-based portraits, how micro-interaction processes at pair level evolve during CPS assessments in an online environment. The assessment is designed for a student pair in the STEM domain. The results show that in despite students’ similar CPS performance scores, variations in micro-interactions occurred across pairs. It is expected that studying these patterns at pair level may provide new insights into CPS processes and so to support acquiring…
Staying at the front line of literature: How can topic modelling help researchers follow recent studies?
2021
Staying at the front line in learning research is challenging because many fields are rapidly developing. One such field is research on the temporal aspects of computer-supported collaborative learning (CSCL). To obtain an overview of these fields, systematic literature reviews can capture patterns of existing research. However, conducting systematic literature reviews is time-consuming and do not reveal future developments in the field. This study proposes a machine learning method based on topic modelling that takes articles from a systematic literature review on the temporal aspects of CSCL (49 original articles published before 2019) as a starting point to describe the most recent devel…
An Early Stage Researcher's Primer on Systems Medicine Terminology
2021
Background: Systems Medicine is a novel approach to medicine, that is, an interdisciplinary field that considers the human body as a system, composed of multiple parts and of complex relationships at multiple levels, and further integrated into an environment. Exploring Systems Medicine implies understanding and combining concepts coming from diametral different fields, including medicine, biology, statistics, modeling and simulation, and data science. Such heterogeneity leads to semantic issues, which may slow down implementation and fruitful interaction between these highly diverse fields. Methods: In this review, we collect and explain more than100 terms related to Systems Medicine. Thes…
Psychiatrists' Attitudes Toward Disruptive New Technologies: Mixed-Methods Study
2018
Background Recent discoveries in the fields of machine learning (ML), Ecological Momentary Assessment (EMA), computerized adaptive testing (CAT), digital phenotype, imaging, and biomarkers have brought about a new paradigm shift in medicine. Objective The aim of this study was to explore psychiatrists’ perspectives on this paradigm through the prism of new clinical decision support systems (CDSSs). Our primary objective was to assess the acceptability of these new technologies. Our secondary objective was to characterize the factors affecting their acceptability. Methods A sample of psychiatrists was recruited through a mailing list. Respondents completed a Web-based survey. A quantitative…
Processi collaborativi nella formazione iniziale degli insegnanti di sostegno
2019
Il contributo mette a fuoco in che modo una concezione comunitaria della scuola offra il contesto all’interno del quale avvengono la crescita ed il cambiamento dei singoli e dell’organizzazione. In particolare si descrive una pratica di lavoro collaborativo realizzata con 195 futuri docenti di sostegno all’interno del corso di Didattica speciale e frequentanti la Scuola di Specializzazione per insegnanti di sostegno nella scuola primaria dell’Università di Palermo. L’apprendimento collaborativo può essere una possibilità per promuovere il processo di cambiamento, in quanto tende a creare un contesto educativo altamente responsabile e aperto alla pluralità, all’interdipendenza e alla recipro…
Une formation pédagogique peut-elle modifier les conceptions de jeunes enseignants universitaires sur l’apprentissage et l’enseignement ?
2012
Nous analysons l’évolution des conceptions de l’apprentissage et de l’enseignement de jeunes enseignants universitaires à l’issue d’une formation en pédagogie universitaire, grâce à des informations de formations collectées lors de sessions de formation de l’Université de Bourgogne. Nous montrons que les conceptions à l’entrée et à la sortie de formation apparaissent variées et que celles-ci sont liées aux disciplines, à l’expérience et au projet professionnel. Les participants considèrent avoir changé de conceptions au terme de la formation. Ceux qui ont des visions nuancées et centrées d’emblée sur l’apprenant sont toutefois davantage influencés par la formation pédagogique.
Konkordances atbalstīta angļu valodas kā svešvalodas apguve vidusskolas skolēniem
2018
Mūsdienu pasauli raksturo tehnoloģiju straujā attīstība, kā arī angļu valodas kā lingua franca statusa nostiprināšanās. Diplomdarba mērķis ir atrast rīku, kas nodrošinātu jauniešiem nepieciešamās svešvalodas prasmes. Pētījumā tika ievākti dati no 203 anketām un piecām intervijām ar mērķi noskaidrot vidusskolas skolēnu valodas apguves ieradumus. Pētījums atklāja, ka vidusskolas skolēni savā ikdienā plaši pielieto tehnoloģijas un ir atvērti tehnoloģijās balstītai svešvalodas apguvei. Tādēļ izaicinājumi, kurus rada angļu valodas kā svešvalodas apguve, piemēram, gramatika, idiomas un pareizrakstība, varētu tikt risināti ar tehnoloģiju starpniecību. Konkordancē balstīta svešvalodas apguve tika p…
