DESDEO : An Open Framework for Interactive Multiobjective Optimization
2018
We introduce a framework for interactive multiobjective optimization methods called DESDEO released under an open source license. With the framework, we want to make interactive methods easily accessible to be applied in solving real-world problems. The framework follows an object-oriented software design paradigm, where functionalities have been divided to modular, self-contained components. The framework contains implementations of some interactive methods, but also components which can be utilized to implement more interactive methods and, thus, increase the applicability of the framework. To demonstrate how the framework can be used, we consider an example problem where the pollution of…
Mathematical Fuzzy Logic in the Emerging Fields of Engineering, Finance, and Computer Sciences
2022
With more than 50 years of literature, fuzzy logic has gradually progressed from an emerging field to a developed research domain, incorporating the sub-domain of mathematical fuzzy logic (MFL) [...]
Environmental Problem-solving and Hands-on Geometry Learning through Storytelling inside a Geodesic Dome : Ice, Honey and Stardust
2019
In this workshop, we introduce a STEAM learning activity based on the construction of geodesic domes. This workshop will engage participants in various preliminary and exploratory constructions, while also applying the geometry of geodesic domes to approximate hemispheres. Various storytelling, role-playing, and environmental connections that can provide needed context for learners of all ages are explored. peerReviewed
Joint attention behaviour in remote collaborative problem solving : exploring different attentional levels in dyadic interaction
2021
AbstractThe current article describes an exploratory study that focussed on joint attention behaviour—the basis of interaction predicting productive collaboration—to better understand collaborative problem solving, particularly its social aspects during remote dyadic interaction. The study considered joint attention behaviour as a socio-linguistic phenomenon and relied on detailed qualitative interaction analysis on event-related measures of multiple observational data (i.e. log files, eye-tracking data). The aim was to illustrate and exemplify how the diverse attentional levels of joint attention behaviour (i.e. monitoring, common, mutual and shared attention) delineated by Siposova and Ca…
Virtual Enterprise Simulation Game as an Environment for Collaborative Creativity and Learning
2021
AbstractWhen employees become accustomed to everyday working habits it can prevent them from generating creative ideas. This familiarity takes the forms of mainly collaborating with familiar colleagues, playing roles that develop over years, and solving encountered problems with proven strategies. This chapter considers how a virtual enterprise simulation game (RealGame) can potentially foster digital creativity and collaborative learning. The game simulates a situation where team members take responsibility for managing a virtual manufacturing company and its supply chain. Theoretically, we consider RealGame a facilitating environment for people to collaborate by offering a safe environmen…
Assessing Online Collaborative Problem Solving Among School Children in Finland : A Case Study Using ATC21S TM in a National Context
2018
Online collaborative problem-solving tasks were piloted in five Finnish schools participating in the Assessment and Teaching of Twenty-first Century Skills (ATC21STM) project. Process stream data from online tasks were captured from 480 Finnish students who explored dyad problem spaces. The log file data were explored to identify indicative behaviours of collaborative problem solving (CPS), which were coded into a series of dichotomous indicators. The Rasch simple logistic model was used to analyse student performance across the social and cognitive dimensions of CPS. Analysis of the Finnish data indicated that the construct can be interpreted using a two-dimensional model, matching the fin…
A Visualizable Test Problem Generator for Many-Objective Optimization
2022
Visualizing the search behavior of a series of points or populations in their native domain is critical in understanding biases and attractors in an optimization process. Distancebased many-objective optimization test problems have been developed to facilitate visualization of search behavior in a two-dimensional design space with arbitrarily many objective functions. Previous works have proposed a few commonly seen problem characteristics into this problem framework, such as the definition of disconnected Pareto sets and dominance resistant regions of the design space. The authors’ previous work has advanced this research further by providing a problem generator to automatically create use…
Symbol, Munch and creativity: metabolism of visual symbols
2010
In this dissertation the relationship between visual symbols and creative thinking is studied through visual, textual and conceptual analysis. The first part of the work focuses on the concept of symbol, the second part on the imagery of Edvard Munch (1863–1944), and the third part on creative thinking. The problematics of visual symbols is approached through the concept of metabolism by assuming that both perceivable and non-perceivable properties of symbols can transform when symbols are used. Because visual symbols are frequently understood as conventional signs with fixed meanings, their perceivable properties are easily ignored. However, symbols can also be unconventionally used, for e…
The Finnish success in Pisa - and some reasons behind it : 2 Pisa 2003
2007
The success of Finnish students in PISA has been a great joy but at the same time a somewhat puzzling experience to all those responsible for and making decisions about education in Finland. At a single stroke, PISA has transformed our conceptions of the quality of the work done at our comprehensive school and of the foundations it has laid for Finland's future education and development of knowledge. Thanks to PISA, Finnish schools and school practices have suddenly been brought into the focus of international attention. Why are Finnish students performing so well? What is the secret behind the Finnish success? In this publication, we as the researchers responsible for the implementation of…
Ongelmanratkaisun opettaminen todennäköisyystehtävissä
2017
Mitä enemmän oppilas tai opiskelija oivaltaa itse, sitä enemmän hän oppii ja nauttii ongelmanratkaisusta. Tämä ajatus toimii lähtökohtana tutkielmassa. Käsiteltävät tehtävät ovat tasoltaan yläkouluun ja / tai lukioon soveltuvia. Tutkielma antaa opettajalle käytännönläheisiä esimerkkejä opetustilanteessa hyödynnettävistä todennäköisyysongelmista. Tehtävistä esitetään useita ratkaisuvaihtoehtoja, jotta opettajan on helpompi samaistua erilaisiin ajattelutapoihin. Mikä tärkeintä, tutkielmaan on kehitetty kysymyksiä, joilla oppijaa voi ohjata hienovaraisesti eteenpäin ratkaisussaan. Tavoitteena on, että ratkoja keksii kysymysten avulla itse ratkaisun kuhunkin ongelmaan. Ongelmanratkaisutaitojen …
