Vuorovaikutus osana opettajan arviointiosaamista (VOPA) -toimintamallin vaiheittaiset kuvaukset
2021
Vuorovaikutus osana opettajan arviointiosaamista (VOPA) -toimintamallin vaiheittaiset kuvaukset edesauttavat opetustilanteisiin liittyvän vuorovaikutuksen systemaattista havainnointia ja reflektointia sekä tarjoavat yhteistä sanastoa teeman käsittelyyn. Tarkastelemalla ryhmän vuorovaikutusta eri vaiheiden kautta, tuetaan ajatusta opettajan vuorovaikutusosaamisen kehittyvästä luonteesta. Opettajaopiskelijat ja opettajat voivat hyödyntää vaiheittaisia kuvauksia oman opetuksensa suunnittelussa, toteutuksessa ja reflektoinnissa. Opettajankouluttajat voivat hyödyntää vaiheittaisia kuvauksia opiskelijoiden opetusharjoittelun tutkimusperustaisessa havainnoinnissa ja ohjaamisessa. Learning interact…
Concept and Development of Modular VLIW Processor Based on FPGA
2010
Modern FPGA chips, with their larger memory capacity and reconfigurability potential, are opening new frontiers in rapid prototyping of embedded systems. With the advent of high density FPGAs it is now possible to implement a high performance VLIW processor core in an FPGA. Architecture based on Very Long Instruction Word (VLIW) processors are an optimal choice in the attempt to obtain high performance level in embedded system. In VLIW architecture, the effectiveness of these processors depends on the ability of compilers to provide sufficient instruction level parallelism(ILP) in program code. Using advanced compiler technology could take these functions, This paper describes research resu…
Multiple modular very long instruction word processors based on field programmable gate arrays
2007
Modern field programmable gate array (FPGA) chips, with their large memory capacity and reconfigurability potential, are opening new frontiers in rapid prototyping of embedded systems. With the advent of high-density FPGAs, it is now possible to implement a high-performance very long instruction word (VLIW) processor core in an FPGA. This paper describes research results about enabling the DSP TMS320 C6201 model for real-time image processing applications by exploiting FPGA technology. We present a modular DSP C6201 VHDL model with a variable instruction set. We call this new development a minimum mandatory modules (M3) approach. Our goals are to keep the flexibility of DSP in order to shor…
Flexible VLIW processor based on FPGA for real-time image processing
2011
Modern FPGA chips, with their larger memory capacity and reconfigurability potential, are opening new frontiers in rapid prototyping of embedded systems. With the advent of high density FPGAs it is now possible to implement a high performance Very Long Instruction Word (VLIW) processor core in an FPGA. With VLIW architecture, the processor effectiveness depends on the ability of compilers to provide sufficient Instruction Level Parallelism (ILP) from program code. This paper describes research result about enabling the VLIW processor model for real-time processing applications by exploiting FPGA technology.

The competency-based approach in developing countries : effects of curricular reforms in Sub-Saharan Africa
2013
For decades, all analyzes converge on the idea of the relative inefficiency of education systems in sub-Saharan Africa. Dropout, repetition, overstaffing, low quality of learning student failure and obsolescence of facilities, teaching materials and teachers, including sometimes the levels and quality of education remain somewhat uncertain, inadequate educational programs. In short, these are some of the ills that plague these systems and confirm the findings made by many reports. Given this weakness finding, educational authorities, supported by international aid mobilized in many countries to improve their systems to qualitatively, but also quantitatively equity because we must not forget…
Spim-Cache: A Pedagogical Tool for Teaching Cache Memories Through Code-Based Exercises
2007
Cache memories represent a core topic in all computer organization and architecture courses offered at universities around the world. As a consequence, educational proposals and textbooks address important efforts to this topic. A valuable pedagogical help when studying cache memories is to perform exercises based on simple algorithms, which allow the identification of cache accesses, for instance, a program accessing the elements of an array. These exercises, referred to as code-based exercises, have a good acceptance among instructors of computer organization courses. Nevertheless, no tool (e.g., simulator) has been developed to be used in undergraduate courses working with this kind of e…
Developments and trends in learning with instructional video
2018
" This special issue provides an overview of some of the main topics addressed in contemporary research on learning with instructional video. The aim of the contributing papers is to take the field of learning with instructional video a step further so as to better understand the circumstances under which instructional videos do and do not improve learning and how instructional videos can be more optimally designed to support learning."
Static and animated presentations in learning dynamic mechanical systems
2009
Abstract In two experiments, we investigated how learners comprehend the functioning of a three-pulley system from a presentation on a computer screen. In the first experiment (N = 62) we tested the effect of static vs. animated presentations on comprehension. In the second experiment (N = 45), we tested the effect of user-control of an animated presentation on comprehension. In both experiments the participants were university students. Comprehension was measured with a test including three comprehension indicators. The first experiment indicated that an animation as well as integrated sequential static frames enhanced comprehension. The second experiment showed that a controllable animati…
Communities in Technology-Enhanced Environments for Learning
2009
The contemporary society addresses complex, interrelated, and interactive global situations to be faced by its citizens. Instead of pursuing solitary actions, this post-modern turn requires its actors to develop capacities to resituate their activities in collective unities and to successfully communicate their actions within these multiple local and global communities. Also in education, the concept of community continues to possess a positive image and the optimistic premises of how communication technologies may enable communities to grow have been widely discussed. For example, in higher education, educational practices (e.g. Virtual University) are more often fixed around Web-based col…
Diversification of adult education with the help of video lectures
2010
For some years now, adult education and working while studying have had an important role in the modern society. Mature-age study brings with it some special features, such as time use limitations, which must be taken into account when creating educational programmes for the students concerned. Above all, flexibility must become a major feature of participation in education. In relation to the Master Studies in Mathematical Information Technology at Kokkola University Consortium, the aim for some years now has been to increase that flexibility by diversifying traditional lecture teaching with the help of real-time and on-demand video lectures. With the help of the results presented in this …
