The Early Bird Gets The Word Games and Play: Creating a Context For Authentic Language Learning
2022
Early foreign language teaching has recently been made compulsory in Finland, making this an area open to development and innovation where policy - makers and teachers play a significant role in creating new kinds of learning environments, operating cultures, and pedagogy for foreign language learning. This article discusses the early foreign language learning landscape in the context of early foreign language learning theory, initial education pedagogy as well as functional foreign language learning. The cornerstone of this study is the Contextual Pedagogical approach to Learning, which creates a bridge between the theory and practice of early foreign language learning, creating an inspiri…
Development of pedagogical design in technology-rich environments for language teaching and learning
2015
This study explores the development of pedagogical design for language teaching and learning in increasingly technology-rich environments. More specifically, it focuses on the process of design, enactment and analysis of language and literacy pedagogies in technology-rich environments. Two substudies are reported in five articles, each of which approaches pedagogical design from a different perspective. The first substudy examined (a) what pedagogical choices language students make in regard to learning objectives, working modes, materials and assessment, and (b) what kind of experiences, attitudes and perceptions were behind these choices. The second substudy focused on developing a design…
Co-designing a pedagogical framework and principles for a hybrid STEM learning environment design
2022
AbstractThe importance of engaging and effective learning environments for science, technology, engineering and mathematics (STEM) has been internationally recognised. However, no comprehensive pedagogical frameworks exist that support STEM learning environment design. In this study, a pedagogical framework and principles for STEM learning environment design were created based on participatory focus groups involving 10–18-year-old students, teachers, school directors, parents, university students and STEM professionals. Representatives of key stakeholder groups in Belarus, Finland, Germany, Greece and Spain (total n = 132) were invited to focus group discussions in which their wishes relate…
Ubiquitous Learning in Appropriate Learning Environments
2018
This article concentrates on blended learning study module that was carried out in class teachers’ adult education. It offered the students versatile, unique, individual and communal possibilities to fully study in authentic contextual environments, exploiting virtual tools. The goal of the planning of this module was to create a learning environment that would give a student an optimal learning experience in versatile, authentic, e-learning environments. In the study, the ubiquitous learning model was tried out in a 6 credits’ study module for class teachers’ adult education that was based on the principles of transformational pedagogy (OED). The module was carried out in flexible and vers…
Live-roleplay as a tool – using real world operation cultures as tools for learning
2014
Anyone, who has ever been at school, has some kind of an idea how does a good learning environment look like. It is an everyday environment for those who attend to school themselves, or it comes close through their children. For some, it is just a distant memory. In any case, most people have an opinion about it. Imagine: straight lines of desks, people sitting alone in a row, daily program split into four to five different lessons, etc. When we think of today´s students - as Tapscott (2009) highlights – they are more open, more active, more broad-minded and less prejudiced than early generations – nonetheless our schools still look similar to those hundred years ago. This article examines …
Critical issues and future prospects of the secondary substation in smart grid context
2014
This paper is focused on the new role of the secondary substation in the smart grids context. This innovative view has been proposed and developed in the framework of two Research Projects: NewCabELARC Project and Reipersei Project. The latter provides a concrete and comprehensive low cost solutions for the smart grid monitoring and control, allowing the real diffusion and integration of Distributed Generation and the full exploitation of Renewable Energy Sources. In this field, this paper shows how the secondary substation (SS) takes the role of smart transducer node where innovative devices can be located, collecting the measurement data coming from the field devices (power and energy met…
Experimental investigation of the optical Kerr effect at large laser intensity: impact on the propagation of a short and intense laser pulse

Higher-order Kerr terms allow ionization-free filamentation in gases
2010
Talk given by J. Kasparian; International audience; Higher-order nonlinear indices, rather than plasma, provide the main defocusing contribution to filamentation in gases at 800 nm. Developing generalized Miller formulae, we discuss the generality of this as a function of the laser wavelength
Origins of radiation-induced attenuation in pure-silica-core and Ge-doped optical fibers under pulsed x-ray irradiation
2020
We investigated the nature, optical properties, and decay kinetics of point defects causing large transient attenuation increase observed in silica-based optical fibers exposed to short duration and high-dose rate x-ray pulses. The transient radiation-induced attenuation (RIA) spectra of pure-silica-core (PSC), Ge-doped, F-doped, and Ge + F-doped optical fibers (OFs) were acquired after the ionizing pulse in the spectral range of [∼0.8–∼3.2] eV (∼1500–∼380 nm), from a few ms to several minutes after the pulse, at both room temperature (RT) and liquid nitrogen temperature (LNT). Comparing the fiber behavior at both temperatures better highlights the thermally unstable point defects contribut…
Near‐IR Radiation‐Induced Attenuation of Aluminosilicate Optical Fibers
2021
The X-ray radiation-induced attenuation (RIA) growth kinetics are studied online in different single-mode aluminosilicate optical fibers in the near-IR (NIR) domain to evaluate their potential in terms of dosimetry. The optical fibers differ by Al contents, core sizes, drawing parameters, and also by a preform deposition process. The data show no dependence of the RIA on all these parameters, a positive result for the design of point or distributed radiation detectors exploiting RIA to monitor the dose. The RIA growth rate is unchanged for dose rates changing from 0.073 to 6.25 Gy(SiO2) s−1, and the RIA linearly increases with the dose up to 2 kGy(SiO2). Small but noticeable RIA changes are…
