Teacher Training for Children with Autism Spectrum Disorders in Finland
2019
This chapter first provides a short description of the historical background and development of special education teacher training in Finland. The relationship between special education and teaching pupils with autism spectrum disorder (ASD) is covered by chronologically presenting the main events, turning points, publications, and people that have had a significant effect on the education of pupils with ASD in Finland. This is followed by a description of the organization of teacher training, in general, and the particular characteristics of teaching pupils with ASD. In the context of ASD, it is essential to examine questions concerning the link between learning as social practice and the …
Contradictions as Drivers for Improving Inclusion in Teaching Pupils with Special Educational Needs
2018
The aim of this paper is to enhance understanding of the contradictions that arise in the drive to improve teaching practices among pupils with special educational needs (SENs). A questionnaire was administrated to 167 classroom teachers, subject teachers, special education teachers and teaching assistants in Finland. The analysis, based on thematic coding and analysis of manifestations of contradictions, revealed contradictions related to artefacts of teaching, participation in the community and school staff’s professional ability to teach SEN pupils in mainstream. Four types of manifestations, namely conflicts, critical conflicts, dilemmas, and double binds, could be identified in the dat…
Enabling Sociability When Using Virtual Reality Applications : A Design Science Research Approach
2019
Immersive virtual reality applications aim at providing an all-encompassing spatial experience where a user can feel like being in another world or dimension. The systems are inherently designed for individual use as the devices disconnect the user from the physical environment. However, the applications are seldom used alone. Specifically, when used for sales and marketing, the user often needs help from other people but also benefits from social interaction as a part of the experience. Design research methodology is applied to three iterative development versions of a virtual-reality application. The focus of the evaluation of the artifacts is in the social use emphasizing three sociabili…
Problem Space Identification for Developing Virtual Reality Learning Environments
2021
Our study argues that the extant literature on virtual reality-based learning environments (VRLEs) currently lacks proper definitions and context descriptions for a problem space, which is fundamental for conducting design science research (DSR). Without properly conducted problem space identification, the most pivotal problems cannot be identified resulting solutions lacking validity and unreliable evaluations. This is a major challenge for the DSR in the educational field, but also for the research on VRLEs. The purpose of this paper is to introduce a novel DSR method to support rigorous problem space identification, which would allow rigorous and profound problem space analysis. The inst…
Controlled polyhedral sweeping processes: existence, stability, and optimality conditions
2021
This paper is mainly devoted to the study of controlled sweeping processes with polyhedral moving sets in Hilbert spaces. Based on a detailed analysis of truncated Hausdorff distances between moving polyhedra, we derive new existence and uniqueness theorems for sweeping trajectories corresponding to various classes of control functions acting in moving sets. Then we establish quantitative stability results, which provide efficient estimates on the sweeping trajectory dependence on controls and initial values. Our final topic, accomplished in finite-dimensional state spaces, is deriving new necessary optimality and suboptimality conditions for sweeping control systems with endpoint constrain…
Técnicas de interpolación weno y su aplicación al procesamiento de imágenes
2010
Un problema común en la teoría de aproximación es la reconstrucción de una función a partir de un conjunto de valores discretos de datos que dan información sobre la función misma. Esta información por lo general viene dada como valores puntuales o medias en celda de la función sobre un conjunto finito de puntos o celdas, respectivamente. La función es aproximada por un interpolante, es decir, por otra función cuyos valores puntuales o medias en celda coinciden con los de la función original. Este interpolante puede ser construido por interpolación lineal. En este caso la exactitud de la aproximación cerca de una singularidad está limitada y depende del orden de la singularidad, de modo que…
La enseñanza de la resolución algebraica de problemas en el entorno de la hoja de cálculo
2010
Nuestra investigación pretendía dar respuesta a: 1) ¿Cuáles son las actuaciones de los estudiantes cuando resuelven problemas en la hoja de cálculo después de haber sido instruidos en la resolución algebraica de problemas en dicho entorno? 2) ¿Cómo influye la enseñanza de la resolución algebraica de problemas en la hoja de cálculo en la competencia de los estudiantes cuando resuelven problemas verbales con lápiz y papel y, en especial, mediante el método cartesiano? Sobre el armazón de los Modelos Teóricos Locales construimos un marco teórico y metodológico que tenía por intención: A) Describir las características de la hoja de cálculo prestando especial atención a la sintaxis y la semántic…
Anàlisi discriminant discreta mitjançant suavització de les correspondències múltiples
2003
El punt de partida del mètode que es presenta en aquest treball és la suposició que les variables discretes procedeixen d'unes subjacents, mixtures de normals, que han estat "tallades" en intervals a cada marginal i permutades posteriorment.D'aquesta manera podem considerar, com és habitual a la literatura, que els factors significatius afecten a la mitjana de les variables subjacents mentre que els no significatius determinen una dispersió gaussiana arreu dels valors centrals de classe. La discretització serà, al seu torn, producte bé de fenòmens d'acumulació-umbralització, típics de molt processos biològics, bé de la imprecisió inherent a l'aparell de mesura. L'esforç es va centrar, com a…

What do we mean by diversity? : the path towards quantification
2018
The concept of biological diversity has evolved from a simple count of species to more sophisticated measures that are sensitive to relative abundances and even to evolutionary divergence times between species. In the course of this evolution, diversity measures have often been borrowed from other disciplines. Biological reasoning about diversity often implicitly assumed that measures of diversity had certain mathematical properties, but most of biologys traditional diversity measures did not actually possess these properties, a situation which often led to mathematically and biologically invalid inferences. Biologists now usually transform the traditional measures to the «effective number …
