Experiential Learning of Chemistry Concepts Using Virtual Reality Technology
2016
Master's thesis Multimedia and Educational Technology MM500 - University of Agder 2016 Chemistry is a wide subject with many theoretical concepts. These theoretical concepts may be hard to grasp without experimental work. In a school class there are often students who are visual, auditory and kinesthetic learners who need appropriate tools for triggering engagement and active learning. This research discusses how adding student activities and experiments using a Virtual Reality (VR) based solution, can contribute to an enhanced learning experience for students during chemistry class. In order to produce a usable interactive VR based solution, this work followed the Human Centered Design pro…
Hybrid Learning Situation as a Challenge for Design
2016
In the paper, we address the physical learning space and focus on designing enabling settings for learning. New practices emerge from an accelerating context change and a rapid adoption of novel ICT solutions. Educational institutions and professionals strive to implement effective settings and instructional methods in order to facilitate an acquisition of the 21st century skills. Little attention is paid to changes that take place at the level of interpersonal communication, let alone their possible impacts in the long run. As the methods and the settings diversify, and the whole learning landscape turns hybrid, a good fit between the setting and the instructional method is a daily design …
Farm-Scale Crop Yield Prediction from Multi-Temporal Data Using Deep Hybrid Neural Networks
2021
Farm-scale crop yield prediction is a natural development of sustainable agriculture, producing a rich amount of food without depleting and polluting environmental resources. Recent studies on crop yield production are limited to regional-scale predictions. The regional-scale crop yield predictions usually face challenges in capturing local yield variations based on farm management decisions and the condition of the field. For this research, we identified the need to create a large and reusable farm-scale crop yield production dataset, which could provide precise farm-scale ground-truth prediction targets. Therefore, we utilise multi-temporal data, such as Sentinel-2 satellite images, weath…
A method for anomaly detection in hyperspectral images, using deep convolutional autoencoders
2017
Menetelmä poikkeavuuksien havaitsemiseen hyperspektrikuvista käyttäen syviä konvolutiivisia autoenkoodereita. Poikkeavuuksien havaitseminen kuvista, erityisesti hyperspektraalisista kuvista, on hankalaa. Kun ongelmaan yhdistetään ennalta tuntematon data ja poikkeavuudet, muodostuu ongelma vielä laajemmaksi. Spektraalisten poikkeavuuksien havaitsemiseen on kehitetty useita eri menetelmiä, mutta spatiaalisten poikkeavuuksien havaitseminen on huomattavasti hankalempaa. Tässä työssä esitellään uudenkaltainen menetelmä sekä spatiaalisten että spektraalisten poikkeavuuksien samanaikaiseen havaitsemiseen. Menetelmä on suunniteltu erityisesti spektraaliselle datalle, mutta soveltuu myös perinteisil…
Project Based Teacher Education to Develop Materials, Instruction and Culture for Phenomenon-Based Steam Projects with Pupils in Schools
2018
In Finland, the most radical ongoing school reform is fading out the borders around school subjects to better prepare young people for future challenges. The new National curricular guidelines include phenomenon - based learning (PhBL) at all school levels. In teacher education, we have adopted a project - based approach for accustoming teachers to this change. Communities of learners with diverse areas of expertize are called together to accomplish projects, along with student teachers. The driving questions are directing the development of materials and guidance to realize cross - subject educational projects with pupils in schools. We are applying Ajzen’s Theory of Planned Behaviour to e…
The role of ICT in primary education : pupils' views about iPad-oriented oral communication tasks in English lessons (5th grade)
2014
Tämä tutkimus käsittelee tietotekniikan roolia alakoulun opetuksessa oppilaan näkökulmasta. Tällä hetkellä alakoulua käyvät oppilaat kuuluvat uuteen, teknologiaorientoituneeseen sukupolveen, ja tämän vuoksi tutkimuksen yhtenä oletuksena oli, että oppilailla olisi näkemyksiä aiheesta. Tutkimuksen tarkoituksena on kartoittaa, kuinka tietotekniikkaa on hyödynnetty ja kuinka sitä voi käyttää luokkahuoneessa sekä lisäksi selvittää oppilaiden ajatuksia ja toiveita siihen liittyen. Esimerkkitapauksena tutkimuksessa käsitellään alakoulun viidennen luokan englannin tunteja ja niillä opetuksessa käytettävää iPad-tablettitietokonetta. Tutkimuksen keskeiset teemat ovat alakoulun opetus, opetusteknologi…
A hot-headed grandma : the use of idiomatic expressions in the compositions of Finnish upper secondary school students
2011
Metaforisuus on tärkeä osa kieltä. Vähitellen myös kielen oppimisessa ja opettamisessa on alettu ymmärtää idiomaattisen kielen merkitys. Uusia tutkimuksia idiomeista ja niiden oppimisesta tehdään jatkuvasti ympäri maailmaa, myös Suomessa. Tämän tutkielman tarkoituksena oli selvittää, paljonko suomalaiset lukio-opiskelijat käyttävät idiomaattisia ilmauksia tuotoksissaan. Lisäksi tutkielmassa etsittiin eroja idiomaattisten ilmausten käytössä eritasoisten opiskelijoiden välillä, tarkasteltiin sitä, millaisia ilmauksia käytetään sekä sitä, millaisia ongelmia kyseisten ilmausten käyttö aiheuttaa. Aineisto kerättiin kahdesta koulusta 3. vuosikurssin kursseilta. Abiturientit eli kolmannen vuoden o…
A Cognitive Architecture for Robotic Hand Posture Learning
2005
This paper deals with the design and implementation of a visual control of a robotic system composed of a dexterous hand and video camera. The aim of the proposed system is to reproduce the movements of a human hand in order to learn complex manipulation tasks or to interact with the user. A novel algorithm for robust and fast fingertips localization and tracking is presented. A suitable kinematic hand model is adopted to achieve a fast and acceptable solution to an inverse kinematics problem. The system is part of a cognitive architecture for posture learning that integrates the perceptions by a high-level representation of the scene and of the observed actions. The anthropomorphic robotic…
Humanoid Cognitive Robots That Learn by Imitating: Implications for Consciousness Studies.
2018
While the concept of a conscious machine is intriguing, producing such a machine remains controversial and challenging. Here we describe how our work on creating a humanoid cognitive robot that learns to perform tasks via imitation learning relates to this issue. Our discussion is divided into three parts. First, we summarize our previously-detailed framework for advancing the understanding of the nature of phenomenal consciousness. This framework is based on identifying computational correlates of consciousness. Second, we describe a cognitive robotic system that we recently developed that learns to perform tasks by imitating human-provided demonstrations. This humanoid robot uses cause-ef…
Immersive Virtual Reality Education Application : Four Development Iterations along Design Science Research Methodology
2022
This study introduces a research and development process of an immersive Virtual Reality (VR) education application. Altogether four application development iterations are showcased along the Design Science Research methodology. The results show how initial problems change and new problems occur during the course of a long-term DSR project with multiple iterations. Moreover, the study results confirm various previous findings, for example, that VR works better on higher learning levels such as application -level and personalization is a way to achieve this. In addition, 360 photos and videos were found to be easy and cost-efficient ways to increase personalization of VR applications. The re…
