Critical Exploration of Flexible Delivery
2020
This work-in-progress research article presents an introductory qualitative study on students' perceptions of a flexibly delivered, modular computer science course. Many contemporary approaches to education rely in various ways on flexible delivery of course content. This is often done to capitalize on modern technology and the web, and to put the student ‘in the center.' However, it is becoming manifest that these approaches may challenge both the students and the equity between them, making it important to understand the effects of flexible delivery in terms of the students. In the voice of our students, flexible delivery was seen as a largely positive approach, reducing stress, promoting…
Designing and Implementing a CSCL-based Course on the Data Security of a Wireless Learning Environment
2012
This article reports on a design-based research (DBR) process for designing and implementing a computer-supported collaborative learning (CSCL) course on the data security of wireless learning environments. The study focuses on examining how university students practice data security when learning on a wireless campus, how data security aspects appear in this study and how students perceive the role of data security in CSCL. The research subjects included six pilot students and eight students enrolled in the course. To promote the reliability of the findings, various kinds of data were used. The data was analysed following the grounded theory approach. The results suggest that data security…
‘The best guess for the future?’ Teachers’ adaptation to open and flexible learning environments in Finland
2021
Finnish education has recently experienced reforms with respect to guidelines forming the curriculum framework for basic education and school architecture. Since 2016, all new schools incorporate open and flexible design, at least to some extent. The more open school design challenges the conventional organisation of space and pre-defined structures and interaction practices. This study investigates how teachers both adapt and are affected by new demands for pedagogy, team teaching and teacher-student relationships. Interview data of 21 teachers of six modern schools are reviewed through thematic analysis. The new school layouts provided some incongruence with the teachers’ aims and their p…
Development of pedagogical design in technology-rich environments for language teaching and learning
2015
This study explores the development of pedagogical design for language teaching and learning in increasingly technology-rich environments. More specifically, it focuses on the process of design, enactment and analysis of language and literacy pedagogies in technology-rich environments. Two substudies are reported in five articles, each of which approaches pedagogical design from a different perspective. The first substudy examined (a) what pedagogical choices language students make in regard to learning objectives, working modes, materials and assessment, and (b) what kind of experiences, attitudes and perceptions were behind these choices. The second substudy focused on developing a design…
Co-designing a pedagogical framework and principles for a hybrid STEM learning environment design
2022
AbstractThe importance of engaging and effective learning environments for science, technology, engineering and mathematics (STEM) has been internationally recognised. However, no comprehensive pedagogical frameworks exist that support STEM learning environment design. In this study, a pedagogical framework and principles for STEM learning environment design were created based on participatory focus groups involving 10–18-year-old students, teachers, school directors, parents, university students and STEM professionals. Representatives of key stakeholder groups in Belarus, Finland, Germany, Greece and Spain (total n = 132) were invited to focus group discussions in which their wishes relate…
Katsaus muodon optimoinnin menetelmiin
2017
Tutkielma esittelee muodon optimoinnin menetelmiä sekä niiden historiaa luoden katsauksen menetelmien kehittymiseen sekä niiden keskinäisiin suhteisiin. Tällaisia ovat esimerkiksi menetelmän matemaattisen teorian “kehittyneisyys” ja ratkaisemisen tehokkuus tai soveltuvuus. Tarkoituksena on muodostaa yleiskuva siitä, mitä menetelmiä muodon optimointiin on jo kehitetty, selvittää, miten ajankohtaisia eri menetelmät ovat, miten menetelmät vertautuvat toisiinsa ja selvittää, mihin eri menetelmät soveltuvat. Lukijan odotetaan selvittävän tarvittavat taustatiedot, sillä tutkielma ei juurikaan esittele muodon optimoinnin matematiikkaa. This thesis presents shape optimization methods, their history…
Dynamic shakedown design of structures under repeated seismic loads
2013
The paper is devoted to the formulation of an optimal design (minimum volume) problem of elastic perfectly plastic structures subjected to suitable combinations of static (fixed) and dynamic (seismic) loads. The structure is constrained to simultaneously respect two different safety criteria; actually, it must exhibit an elastic shakedown behaviour for the combination of loads characterizing the serviceability conditions and it must prevent the instantaneous collapse for the highest expected load condition (combination of loads characterized by the presence of fixed loads and maximum expected intensity of seismic action). The shakedown limit behaviour for the optimal structure will be impos…
Comparison between unrestricted dynamic shakedown design and a new probabilistic approach for structures under seismic loadings
2014
The paper concerns a study related to the comparison between two different approaches utilized for the formulation of an optimal shakedown design problem for elastic plastic frame structures subjected to a combination of fixed and seismic loading. The first formulation utilizes the unrestricted dynamic shakedown theory, while the second one is based on a new probabilistic approach. The comparison is effected in terms of mathematical formulations, in terms of adopted loading models and in terms of numerical results. The performed applications are related to plane steel frames.
Water distribution network robust design based on energy surplus index maximization
2015
The aim of this paper is to show that energy surplus indices, such as resilience index, besides providing a very good indirect measure of water distribution network reliability to be adopted during the design phase, represent also a valuable and effective indicator of the robustness of the network in alternative network scenarios, and can thus be profitably used in condition of future demands uncertainty. The methodology adopted consisted of (I) multi-objective design optimization performed in order to minimize construction costs while maximizing the resilience index; (II) retrospective performance assessment of the alternative solutions of the Pareto front obtained, under demand conditions…
Surrogate-assisted multicriteria optimization: Complexities, prospective solutions, and business case
2017
Complexity in solving real-world multicriteria optimization problems often stems from the fact that complex, expensive, and/or time-consuming simulation tools or physical experiments are used to evaluate solutions to a problem. In such settings, it is common to use efficient computational models, often known as surrogates or metamodels, to approximate the outcome (objective or constraint function value) of a simulation or physical experiment. The presence of multiple objective functions poses an additional layer of complexity for surrogate-assisted optimization. For example, complexities may relate to the appropriate selection of metamodels for the individual objective functions, extensive …
