Mediated learning materials: visibility checks in telepresence robot mediated classroom interaction
2021
Videoconferencing is increasingly used in education as a way to support distance learning. This article contributes to the emerging interactional literature on video-mediated educational interaction by exploring how a telepresence robot is used to facilitate remote participation in university-level foreign language teaching. A telepresence robot differs from commonly used videoconferencing set-ups in that it allows mobility and remote camera control. A remote student can thus move a classroom-based robot from a distance in order to shift attention between people, objects and environmental structures during classroom activities. Using multimodal conversation analysis, we focus on how partici…
Identification of Reading Difficulties by a Digital Game-Based Assessment Technology
2020
Computerized game-based assessment (GBA) system for screening reading difficulties may provide substantial time and cost benefits over traditional paper-and-pencil assessment while providing means also to individually adapt learning content in educational games. To study the reliability and validity of a GBA system to identify struggling readers performing below a standard deviation from mean in paper-and-pencil test either in raw scores and grade-normative scores, a large-scale study with first to fourth grade students ( N = 723) was conducted, where GBA was administrated as a group test by tablet devices. Overall, the results indicated that the GBA can be successfully used to identify st…
Grammar is the heart of language : grammar and its role in language learning among Finnish university students
2015
This article presents and discusses views on grammar and its role in formal language learning amongst Finnish university students. The results are based on a questionnaire which was distributed to students at the University of Jyväskylä as part of institutional action research. The background to the project was a feeling amongst some teachers of increased divergence between student respectively language teacher understandings of the role of grammar in language teaching. This concern raised the need to find out how students view grammar. The knowledge about thoughts on grammar amongst students would then help teachers to adjust and adept the way grammar is used in language teaching. The main…
Evaluation of Ensemble Machine Learning Methods in Mobile Threat Detection
2017
The rapid growing trend of mobile devices continues to soar causing massive increase in cyber security threats. Most pervasive threats include ransom-ware, banking malware, premium SMS fraud. The solitary hackers use tailored techniques to avoid detection by the traditional antivirus. The emerging need is to detect these threats by any flow-based network solution. Therefore, we propose and evaluate a network based model which uses ensemble Machine Learning (ML) methods in order to identify the mobile threats, by analyzing the network flows of the malware communication. The ensemble ML methods not only protect over-fitting of the model but also cope with the issues related to the changing be…
Environmental Problem-solving and Hands-on Geometry Learning through Storytelling inside a Geodesic Dome : Ice, Honey and Stardust
2019
In this workshop, we introduce a STEAM learning activity based on the construction of geodesic domes. This workshop will engage participants in various preliminary and exploratory constructions, while also applying the geometry of geodesic domes to approximate hemispheres. Various storytelling, role-playing, and environmental connections that can provide needed context for learners of all ages are explored. peerReviewed
Building a Maturity Model for Developing Ethically Aligned AI Systems
2021
Ethical concerns related to Artificial Intelligence (AI) equipped systems are prompting demands for ethical AI from all directions. As a response, in recent years public bodies, governments, and companies have rushed to provide guidelines and principles for how AI-based systems are designed and used ethically. We have learned, however, that high-level principles and ethical guidelines cannot be easily converted into actionable advice for industrial organizations that develop AI-based information systems. Maturity models are commonly used in software and systems development companies as a roadmap for improving the performance. We argue that they could also be applied in the context of develo…
A Robust Minimal Learning Machine based on the M-Estimator
2017
In this paper we propose a robust Minimal Learning Machine (R-RLM) for regression problems. The proposed method uses a robust M-estimator to generate a linear mapping between input and output distances matrices of MLM. The R-MLM was tested on one synthetic and three real world datasets that were contaminated with an increasing number of outliers. The method achieved a performance comparable to the robust Extreme Learning Machine (R-RLM) and thus can be seen as a valid alternative for regression tasks on datasets with outliers. peerReviewed
A Brief History of the Peer-Group Mentoring Model in Finland: Struggling for Space in a Contested Niche
2020
The aim of this article is to introduce and reflect on the development of mentoring in Finland as implemented in the form of the Peer-Group Mentoring (PGM) model. Firstly, the main characteristics and principles of the PGM model are introduced, after which experiences from implementing the model are analysed based on a literature review. We examine the following research questions: (1) How have the mentoring practices of newly qualified teachers developed towards the PGM model within the educational ecosystem in Finland? (2) How has the PGM model found its relational space (‘ecological niche’) in this ecosystem? and (3) How has PGM been experienced by mentors and mentees in terms of profess…
Informal learning contexts in the construction of physical education student teachers’ professional identity
2022
This study aimed to investigate the significance of informal learning contexts in physical education (PE) student teachers’ professional identity construction. It addressed two research questions: How do informal learning contexts contribute to the construction of PE student teachers’ professional identity? What forms of relationships can be identified between the informal and formal contexts of learning in PE student teachers’ professional identity construction? The data consisted of 20 semi-structured interviews with PE student teachers during the final teaching practice period. The data were analysed using structural and pattern coding methods. The analysis revealed that informal learnin…
Professional identity in changing workplaces : Why it matters, when it becomes emotionally imbued, and how to support its agentic negotiations
2022
This chapter addresses professional identity in the workplace. The relevance of the topic derives from current trends in working life, in which constant changes require continuous professional identity negotiations. In addition, employees are increasingly obliged to recognise and make visible their professional identity in order to navigate and survive in the complexities of working life. This chapter provides an overview of the conceptual frameworks, topics, and empirical evidence pertaining to professional identity, as presented in workplace learning literature. From this, it provides suggestions for researching and elaborating professional identity, with particular attention to relationa…
