Social sensitivity:a manifesto for CSCL research
2021
International audience; Technologies for computer-supported collaborative learning (CSCL) are playing an increasingly prominent role in educational contexts, especially as teachers and students strive to deal with pandemic-related constraints. However, the technologies being used for collaboration on a daily basis are not sufficiently equipped to promote collaborative learning as both a cognitive and a socio-emotional process. They may even run the risk of hindering the constructive exchange of ideas and provoking disputes and negative encounters. In this squib, we argue that the field of CSCL is failing to address this risk, because our research efforts are far too scattered and siloed. We…
Theoretical and pedagogical perspectives on orchestrating creativity and collaborative learning
2011
The role of teacher is increasingly related to designing and arranging collaborative learning situations in which fruitful and creative group work may occur. This thematic review presents recent studies on creativity and collaborative learning from the perspective of the teacher as conductor of learning processes. The precondition for the design and orchestration of these kinds of learning situations is analysing and understanding of creative and collaborative processes and their contextual adaption. Thus, the first section of this review focuses on the theoretical vantage points of creativity and collaborative learning mainly from socio-cultural perspective. Based on this theoretical groun…
Using tablets as tools for learner-generated drawings in the context of teaching the kinetic theory of gases
2014
Even though research suggests that the use of drawings could be an important part of learning science, learnergenerated drawings have not received much attention in physics classrooms. This article presents a method for recording students’ drawings and group discussions using tablets. Compared to pen and paper, tablets offer unique benefits, which include the recording of the whole drawing process and of the discussion associated with the drawing. A study, which investigated the use of drawings and the need for guidance among Finnish upper secondary school students, is presented alongside ideas for teachers on how to see drawing in a new light. peerReviewed
Collaborative 3D learning games for future learning: teachers’ instructional practices to enhance shared knowledge construction among students
2013
Collaborative games will enable new kinds of possibilities for learning. In the future, the goal of game-based learning should be to introduce new ideas and deepen in-depth understanding of learners. However, studies have shown that shared high-level knowledge construction is a challenging process. Moreover, thus far, few empirical studies have examined what constitutes the teacher’s role in games. The focus of this paper is to investigate teachers’ real-time instructional activities in a scripted 3D game setting. Our hypothesis is that groups with real-time teacher instruction will come up with more shared knowledge construction that can be considered productive than groups studying withou…
The case of literacy motivation : Playful 3D immersive learning environments and problem-focused education for blended digital storytelling
2018
The University of Patras' Library Services designed and offered to primary and secondary schools the pilot educational program “From the Ancient to the Modern Tablets”, featuring immersive multimedia learning experiences about the book history. The pilot program consisted of three stages: a playful library tour, followed by an interactive game-based digital storytelling activity with game elements, and a collaborative creative reflective hands-on activity. Utilizing the avatar psychology power, the visualization and simulation affordances of 3D immersive learning environments and the appeal of storytelling and game-based learning, the “gamified” blended narrative on the book evolution enabl…
A Phenomenographic Research Study of Students’ Conceptions of Mobile Learning: An Example From Higher Education
2019
This article aims to identify different ways of using mobile devices in students’ learning in higher education. This qualitative research presents the findings from a phenomenographic research of students’ conceptions of mobile learning (m-learning) in higher education. A cohort of 16 students from four universities of Bangladesh took part in semi-structured interviews to explore their in-depth understandings and experiences of m-learning. The findings indicate that university students perceived five qualitatively different ways of using mobile devices in their learning: a medium for communication; a medium for management of learning materials; a tool for effective learning; a means for co…
Scripting as a pedagogical method to guide collaborative writing : university students' reflections
2020
A collaboration script is a set of instructions used to improve collaborative learning among students in technology-enhanced environments. Previously, university students’ perspective has been under-represented in the study on collaboration scripts. In this article, we focus on understanding students’ experiences in a scripted collaborative writing task, especially from the perspective of following the script. The study was conducted among undergraduate students (N = 91) taking a master-level educational science course at one university each in Finland and Belgium. Divided into 25 groups, each with three to five members, the students worked on collaborative writing tasks. During their share…
Microlensing constraints on axion stars including finite lens and source size effects
2021
A fraction of light scalar dark matter, especially axions, may organize into Bose-Einstein condensates, gravitationally bound clumps, "boson stars", and be present in large number in galactic halos today. We compute the expected number of gravitational microlensing events of clumps composed of the ordinary QCD axion and axion-like-particles and derive microlensing constraints from the EROS-2 survey and the Subaru Hyper Suprime-Cam observation. We perform a detailed lensing calculation, including the finite lens and source size effects in our analysis. We constrain the axion mass in terms of the fraction of dark matter collapsed into clumps, the individual clump densities, and the axion self…
Can QCD Axion Stars explain Subaru HSC microlensing?
2021
A non-negligible fraction of the QCD axion dark matter may form gravitationally bound Bose Einstein condensates, which are commonly known as axion stars or axion clumps. Such astrophysical objects have been recently proposed as the cause for the single candidate event reported by Subaru Hyper Suprime-Cam (HSC) microlensing search in the Andromeda galaxy. Depending on the breaking scale of the Peccei-Quinn symmetry and the details of the dark matter scenario, QCD axion clumps may form via gravitational condensation during radiation domination, in the dense core of axion miniclusters, or within axion minihalos around primordial black holes. We analyze all these scenarios and conclude that the…
Euclid preparation XV. Forecasting cosmological constraints for the Euclid and CMB joint analysis
2022
The combination and cross-correlation of the upcoming $Euclid$ data with cosmic microwave background (CMB) measurements is a source of great expectation since it will provide the largest lever arm of epochs, ranging from recombination to structure formation across the entire past light cone. In this work, we present forecasts for the joint analysis of $Euclid$ and CMB data on the cosmological parameters of the standard cosmological model and some of its extensions. This work expands and complements the recently published forecasts based on $Euclid$-specific probes, namely galaxy clustering, weak lensing, and their cross-correlation. With some assumptions on the specifications of current and…
