Leadership in Finnish comprehensive school core curricula since the 1970s
2014
Tiivistelmä – Abstract Suomen peruskoulujärjestelmä sai alkunsa vuonna 1970 ja samana vuonna julkaistiin ensimmäinen peruskoulun opetussuunnitelma. Seuraavat opetussuunnitelmauudistukset toteutettiin vuosina 1985, 1994 ja 2004. Parhaillaan Suomessa kehitetään uutta peruskoulun opetussuunnitelmaa, joka on tarkoitus ottaa käyttöön vuonna 2016. Tässä tutkimuksessa tarkasteltiin johtajuuden ja opetussuunnitelman välistä suhdetta. Tutkimus toteutettiin laadullisena sisällönanalyysina, jossa aineiston muodostivat viralliset opetussuunnitelmat ja kaksi asiantuntijahaastattelua. Tutkimustulokset analysoitiin summatiivisen sisällönanalyysin menetelmin ja tulokset kuvattiin tulkinnallisella menetelmä…
Versatile Direct and Transpose Matrix Multiplication with Chained Operations: An Optimized Architecture Using Circulant Matrices
2016
With growing demands in real-time control, classification or prediction, algorithms become more complex while low power and small size devices are required. Matrix multiplication (direct or transpose) is common for such computation algorithms. In numerous algorithms, it is also required to perform matrix multiplication repeatedly, where the result of a multiplication is further multiplied again. This work describes a versatile computation procedure and architecture: one of the matrices is stored in internal memory in its circulant form, then, a sequence of direct or transpose multiplications can be performed without timing penalty. The architecture proposes a RAM-ALU block for each matrix c…
Synthesizing on a reconfigurable chip an autonomous robot image processing system
2003
This paper deals with the implementation, in a high density reconfigurable device, of an entire log-polar image processing system. The log-polar vision reduces the amount of data to be stored and processed, simplifying several vision algorithms and making it possible the implementation of a complete processing system on a single chip. This image processing system is specially appropriated for autonomous robotic navigation, since these platforms have typically power consumption, size and weight restrictions. Furthermore, the image processing algorithms involved are time consuming and many times they have also real-time restrictions. A reconfigurable approach on a single chip combines hardwar…
Ant Colony Models for a Virtual Educational Environment Based on a Multi-Agent System
2008
We have designed a virtual learning environment where students interact through their computers and with the software agents in order to achieve a common educational goal. The Multi-Agent System (MAS) consisting of autonomous, cognitive and social agents communicating by messages is used to provide a group decision support system for the learning environment. Learning objects are distributed in a network and have different weights in function of their relevance to a specific educational goal. The relevance of a learning object can change in time; it is affected by students', agents' and teachers' evaluation. We have used an ant colony behavior model for the agents that play the role of a tu…
Student–teacher dialectic in the co-creation of a zone of proximal development: an example from kindergarten mathematics
2020
This paper reports on a case study which explores the co-creation of a zone of proximal development (ZPD) in a mathematics teaching-learning activity in a Norwegian kindergarten. To capture the com...
Teacher orchestration of classroom interaction in science: exploring dialogic and authoritative passages in whole-class discussions
2019
Whereas science is fundamentally a result of a dialogic debate, the authoritative approach has been conceived of as a fundamental part of school science. Dialogic interactions encompass the mutual appreciation of different ideas manifested in teacher supportiveness toward students and, in authoritative interactions, the focus is more on the science’s or teacher’s point of view. Whereas dialogic and authoritative interactions have been viewed as oppositional in recent educational research, authoritative interactions could well be the seed for and give strength and meaning to dialogic interactions, and thus, to the overall dialogue. The focus in this study is on the interplay between authorit…
New TEL Environments for Vocational Education – Teacher’s Instructional Perspective
2015
Modern vocational education is increasingly taking place in new technology-enhanced learning (TEL) settings. On the one hand, vocational education can benefit from the opportunities of technological development. On the other hand, such technologies may create new challenges for teachers. Therefore, there is a particular need to pay more attention to the dialogic pedagogical approaches in which teaching should be seen as a dialogical practice involving teacher-student interactions that create contextual opportunities for teachers to trigger students’ learning in new TEL settings. This article reports on an exploratory study about the different ways in which teachers’ instructional activities…
Ziel- und leistungsdifferenziertes Lernen und Arbeiten
2020
An increasing variety of language (learning) biographies characterize a differentiation of goals and achievements in foreign language teaching. At the same time, they have to comply with curricula and assessment standards. The paper points out and reflects possible steps and teaching methods that could be used.
Undergraduate experiment with fractal diffraction gratings
2011
We present a simple diffraction experiment with fractal gratings based on the triadic Cantor set. Diffraction by fractals is proposed as a motivating strategy for students of optics in the potential applications of optical processing. Fraunhofer diffraction patterns are obtained using standard equipment present in most undergraduate physics laboratories and compared with those obtained with conventional periodic gratings. It is shown that fractal gratings produce self-similar diffraction patterns which can be evaluated analytically. Good agreement is obtained between experimental and numerical results. © 2011 IOP Publishing Ltd.
Translating EU text in the English BA programme: exploring teachers' views and practices
2014
Recent research into using translation as a communicative and functional activity in foreign language learning and teaching has pointed out a wide range of benefits for advanced language learners. The research reported in this paper involved teachers teaching translation in the EU-specialisation module integrated into the English bachelor’s degree programme in Hungary. The survey set out to explore teachers’ instructional practices as well as their views and experiences regarding translation. Results indicate that translation in this pedagogical setting is used not merely as a tool to develop language competence and other generic skills, but is regarded as a useful skill in its own right. T…
