Drawing Cartoon Strips as a Learning Tool in Fostering the Learning of Titration in Pre-service Chemistry Education
2021
In this study, static visual displays of titration created by the university-level pre-service chemistry education students was investigated. The aim for the students was to learn the theory of titrations, using self-prepared cartoon strips with supportive texts. Attention was paid to the titration cartoon strips students made which were suitable for both learning and teaching purposes. The basis of this study was students’ own drawings: students observed and visualized the titration process, and built their own representation of it. Simple models were created using pencil and paper. The goals were to determine how students regard the learning tool, how drawing cartoon strips helps their le…
Employee opportunities for self-directed learning at technology organisations : features and frames of self-directed learning projects
2020
The importance of self-directed learning (SDL) in a business environment has been highlighted as a way to increase an organisation’s competitiveness and innovativeness. While organisations increasingly require SDL from employees, less attention is paid to the situations and frames enabling it. This study examines self-directed learning projects (SDLPs), situations in which SDL is realised as an individual or collective phenomenon. Based on ethnographic research, this study’s data consisted of field notes, field records and interviews. I used analysis of key incidents and ethnographic content analysis as an analytical tools. Four types of SDLPs was identified in the organisations studied: or…
Professional identity in relation to vocational teachers’ work : an identity-centred approach to professional development
2018
This paper reports a study on teachers’ professional identity and work in vocational education. The findings showed that vocational teachers’ work included vocational teaching within the school, developmental work, technology-enhanced work, professional duties outside the school, and educational duties within the school. Furthermore, the study revealed the harmonious and tensioned relationships between these elements of the work and teachers’ identities. Recognition of the nuanced nature of these relationships provides a perspective for promoting teachers’ professional development. From a practical perspective, there is a need to support vocational teachers’ identity work and the adoption o…
Las citas como práctica del uso de las fuentes : las citas de fuentes en línea seleccionados por los estudiantes en sus trabajos
2020
This study examined upper secondary school students’ citations of self-selected online sources in their essays. Students (n = 140) conducted online inquiry about either effects of social media on people’s quality of life (SM) or allowance of genetic manipulation of organisms (GMO). Students, working either individually or in pairs, explored online sources with the help of a graphic organizer, after which they composed their essays. To capture the quality of citations identified in the essays, they were evaluated in terms of accuracy and richness of source features. Further, regression analysis was used to examine the effect of topic, grade level and work mode on the number and quality of ci…
Tehostettu tuki ja oppimisvaikeuksien ennaltaehkäisyn ideaalimalli esiopetuksessa : oppilashuollon asiantuntijoiden käsityksiä
2012
Varhainen puuttuminen on ollut varhaiskasvatuksessa jo pitkään yhtenä toiminta-ajatuksena, ja perusopetuslain muutos vuonna 2010 toi esiopetukseen uuden tukimuodon, tehostetun tuen. Oppimisvaikeudet ovat yksi osa-alue, johon varhaisen puuttumisen ja tehostetun tuen avulla voitaisiin vaikuttaa. Tässä pro gradu -tutkimuksessa selvitettiin oppilashuollon asiantuntijoiden käsityksiä tehostetusta tuesta esiopetuksessa sekä näkemyksiä oppimisvaikeuksien ennaltaehkäisyyn keskittyvästä ideaalimallista. Tutkimus on laadullinen tutkimus ja siinä käytettiin fenomenografista tutkimusotetta. Tutkittavien joukko muodostui yhdeksästä oppilashuollon asiantuntijasta, joita haastateltiin teemahaastatteluin s…
Tehostettu tuki opettajien, vanhempien ja oppilaiden kokemana : tapaustutkimus yhden alakoulun toimintamalleista
2014
Tutkimuksen tarkoituksena oli selvittää opettajien, huoltajien sekä oppilaiden kokemuksia tehostetun tuen toimintamalleista. Opettajien, vanhempien ja oppilaiden kokemukset tehostetun tuen toimintamalleista ovat merkityksellisiä, sillä niiden kautta voidaankehittää oppilaille annettavaa tukea. Tutkimus toteutettiin tapaustutkimuksena. Tutkimusaineisto on kerätty puolistrukturoituina teemahaastatteluina. Haastateltavia oli yhteensä kahdeksan, 2 erityisopettajaa, 2 luokanopettajaa, 2 huoltajaa sekä 2 oppilasta. Aineiston analysoinnissa käytettiin aineistolähtöistä sisällönanalyysiä, koska tarkoituksena oli pyrkiä rakentamaan tutkimusaineistosta teoreettinen kokonaisuus. Näin ollen analyysiyks…

CCTVCV: Computer Vision model/dataset supporting CCTV forensics and privacy applications
2022
The increased, widespread, unwarranted, and unaccountable use of Closed-Circuit TeleVision (CCTV) cameras globally has raised concerns about privacy risks for the last several decades. Recent technological advances implemented in CCTV cameras, such as Artificial Intelligence (AI)-based facial recognition and Internet of Things (IoT) connectivity, fuel further concerns among privacy advocates. Machine learning and computer vision automated solutions may prove necessary and efficient to assist CCTV forensics of various types. In this paper, we introduce and release the first and only computer vision models are compatible with Microsoft common object in context (MS COCO) and capable of accurately…
CCTV-FullyAware: toward end-to-end feasible privacy-enhancing and CCTV forensics applications
2022
It is estimated that over 1 billion Closed-Circuit Television (CCTV) cameras are operational worldwide. The advertised main benefits of CCTV cameras have always been the same; physical security, safety, and crime deterrence. The current scale and rate of deployment of CCTV cameras bring additional research and technical challenges for CCTV forensics as well, as for privacy enhancements. This paper presents the first end-to-end system for CCTV forensics and feasible privacy-enhancing applications such as exposure measurement, CCTV route recovery, CCTV-aware routing/navigation, and crowd-sourcing. For this, we developed and evaluated four complex and distinct modules (CCTVCV [1], OSRM-CCTV [2],…
