Technology-enhanced or Technology-exhausted Learning in Adult Migrant Literacy Education in Finland : Exploring Teachers’ Experiences and Views in Pr…
2023
This exploratory mixed data study investigated the role of technology in adult migrant language and late literacy education in Finland. In addition to an online pre-pandemic survey targeted at Finnish language and literacy teachers, four in-service teachers were interviewed during the COVID-19 pandemic in late 2020. With means of qualitative content analysis an account of teachers’ individual experiences and views of technology-equipped language and literacy learning was generated. Problematic issues were the use of devices for educational purposes, lacking user experience, inadequate provision of suitable devices, IT courses, and insufficient support for learners and teachers, causing ineq…

Individual Creativity and Career Choices of Pre-teens in the Context of a Math-Art Learning Event
2021
A sample of 392 students (aged 12-13 years, M± SD: 12. 52% girls) completed a learning module integrating informal hands-on mathematics and arts activity (extending STEM to STEAM). Within a 140 minute workshop period participants worked with commercially available ‘4Dframe’ Math and STEAM learning toolkits to design and create original, personal and individual geometrical structures. Two science pedagogues acted as tutors supervising the process and intervened only when needed. A pre-/post-test design monitored individual creativity, relative autonomy, and career choice preference. Path analysis elaborated the role of creativity (measured with two subscales: act and flow), and it showed tha…
The effects of socio-scientific issue based inquiry learning on pupils’ representations of landscape
2016
AbstractResearch has demonstrated that socio-scientific issues based inquiry learning has significant advantages for learning outcomes and students’ motivation. Further, a successful understanding of landscapes in environmental and geographical education can be achieved by combining informal learning environments with school education. Therefore this case study focuses on how socio-scientific issues based inquiry learning carried out in school and in a Nature Park, influences primary school pupils’ (n = 36) representations of landscapes. The pupils were asked to draw and write about landscape both before and after intervention. The data was analyzed qualitatively and quantitatively to inves…
Developing Primary School Students’ Formal Geometric Definitions Knowledge by Connecting Origami and Technology
2019
In this paper, we present opportunities with the uses of origami and technology, in our case GeoGebra, in teaching formal geometric definitions for fifth-grade primary school students (11-12yrs). Applying origami in mathematical lessons is becoming to be recognized as a valuable tool for improving students’ mathematical knowledge. In previous studies, we developed origami and technology activities for high-school mathematics, but we wanted to explore if such approach would work in primary school as well. For this reason, we chose a flat origami model оf the crane and we used this model to introduce students to basic geometrical notions and definitions, such as points, lines, intersections o…
Osculating spheres to a family of curves.
2021
The authors study the extrinsic conformal geometry of space forms involving pencils of circles or spheres. They consider curves orthogonal to a foliation of an open set of a 3-sphere by spheres and prove that the osculating spheres to the curves at points of a leaf form a pencil. They first prove the analogous result in a lower-dimensional case, that is, foliations of the 2-dimensional sphere and their orthogonal foliations. The 3-dimensional result, that is, the result for a foliation of (an open subset of) the 3-dimensional sphere by 2-dimensional spheres, is obtained using the de Sitter space, which is a model for the set of oriented spheres of the 3-dimensional sphere.
Testing the nature of the Λ(1520)-resonance in proton-induced production
2006
The $\Lambda(1520)$ resonance has been recently studied in a unitarized coupled channel formalism with $\pi\Sigma(1385)$, $K\Xi(1530)$, $\bar{K}N$ and $\pi\Sigma$ as constituents blocks. We provide a theoretical study of the predictions of this model in physical observables of the $pp\to pK^+K^-p$ and $pp\to pK^+\pi^0\pi^0\Lambda$ reactions. In particular, we show that the ratio between the $\pi^0\pi^0\Lambda$ and $K^-p$ mass distributions can provide valuable information on the ratio of the couplings of the $\Lambda(1520)$ resonance to $\pi\Sigma(1385)$ and $\bar{K}N$ that the theory predicts. Calculations are done for energies which are accessible in an experimental facility like COSY at …
Semantically Closed Languages Reconsidered. Re-Reading Alfred Tarski
2019
The text shows that Alfred Tarski studied semantics to define a true sentence in a m a t e r i a l l y a d e q u a t e and f o r m a l l y c o r r e c t way, and in effect he defined the co-called semantically closed languages as a subset of formalized ones, in which the occurrence of the Liar paradox is imminent because of the features of the language used. This is one of the points of Tarski’s heritage where misunderstandings constantly occur among the readers of Tarski‘s work, and that is why the present paper may prove to be useful by presenting suitable excerpts from the original Tarski’s text. Tarski found additional limiting criteria applicable to formalised languages, which may prev…
Zjawisko korupcji w demokracji skonsolidowanej. Przypadek Finlandii
2017
Zjawisko korupcji w stabilnych, zamożnych państwach demokratycznych określanych mianem demokracji skonsolidowanych było przez długi czas ignorowane przez badaczy. Jednak w ostatnim dziesięcioleciu XX wieku pojawiły się czynniki, które doprowadziły do instytucjonalizacji kwestii korupcji w dojrzałych demokracjach. Tę zmianę obserwujemy również w Finlandii, która według Indeksu Percepcji Korupcji publikowanym przez Transparency International jest postrzegana jako jedno z najmniej skorumpowanych państw świata. Jednak również w tym kraju możemy odnaleźć specyficzne formy korupcji. Celem artykułu jest charakterystyka tzw. sieci starych braci jako praktyk korupcyjnych charakterystycznych dla Finl…
