âAre You OK?â Studentsâ Trust in a Chatbot Providing Support Opportunities
Best Paper Award of the 8th International Conference on Learning and Collaboration Technologies Presented in the context of HCI International 2021 24-29 July 2021Chatbots show promise as a novel way to provide support to students. However, a central issue with new technologies such as chatbots is whether students trust the technology. In the present study, we use a chatbot to proactively offer academic and non-academic support to students (N = 274) in a Finnish vocational education and training (VET) organization. Students responded to the chatbot with a very high response rate (86%), and almost one-fifth (19%) of the respondents disclosed a need for support. Survey with a subset of participants (N = 49) showed satisfactory trust (total trust score 71% as measured by a human-computer trust scale) and satisfaction (average of 3.83 as measured by a five-point customer satisfaction instrument) with the chatbot. Trust was positively correlated with satisfaction as well as studentsâ likelihood to respond to the chatbot. Our results show that this kind of approach is applicable for recognizing studentsâ latent needs for support. Future studies should target the formation of trust in more detail and cultural differences in trusting chatbots.Chatbots show promise as a novel way to provide support to students.

Evaluation of a snowmobile track motion resistances with multibody dynamics simulation
Abstract. In this work, target is to build and validate a simulation model of a snowmobile track entity with multibody dynamics simulation software Adams. A full vehicle snowmobile simulation model is also explored. Before there has been a problem with the track model being inaccurate. The focus on this thesis is on implementing a track model, but a full vehicle model is also discussed and presented as the work with the model will continue. Existing tracked vehicle theory is studied and presented how Adams tracked vehicle plugin utilizes these theories.
Research consists of simulations with the track model were driven with a real snowmobile and measured for torque and velocity data. Model validation proves that the track model acts quite accurately up to 25 km/h drive speed but with 50 km/h speed the model becomes unstable. With 10 km/h speed simulation result error is 19,87 % and with 25 km/h simulation result error is 1,17 %. In the future the model will be further improved with building a proper chassis and validating the full vehicle model. Knowledge gained from this thesis may be used with simulating a snowmobile before production phase accurately and the model can be used for studying the motion resistances of a snowmobile track. This type of track model may be built to any tracked vehicle and validated in the way done in this thesis.Moottorikelkan telaston ajovastuksien mÀÀrittÀminen monikappaledynamiikka simuloinnilla. TiivistelmÀ. TÀssÀ työssÀ tavoitteena on rakentaa ja validoida moottorikelkan telaston simulointimalli Adams ohjelmistolla. Telastomallin lisÀksi tarkastellaan myös kokonaisen moottorikelkan simulointimallia. Aiemmin on ollut ongelmana telamattomallin epÀtarkkuus. TyössÀ keskitytÀÀn etenkin kumitelamattomallin implementointiin, mutta kokonaista ajoneuvokokoonpanoa arvioidaan lisÀksi, sillÀ työ mallin kanssa jatkuu. Olemassa olevaa tela-ajoneuvoteoriaa tutkitaan ja esitetÀÀn, kuinka Adamsin telaajoneuvo lisÀosassa hyödynnetÀÀn kyseisiÀ teorioita.
Tutkimus koostuu simulaatioista telamattomallilla sellaisilla nopeuksilla, joita tutkimuksen aikana on mitattu todellisesta moottorikelkasta vÀÀntötiedon kanssa. Validoinnissa todistetaan, ettĂ€ telamalli kĂ€yttĂ€ytyy suhteellisen tarkasti 25 km/h nopeuteen asti, mutta 50 km/h nopeudessa malli muuttuu epĂ€vakaaksi. 10 km/h nopeudella simulaatiotuloksien virhe on 19,87 % verrattuna mitattuihin tuloksiin ja 25 km/h nopeudella simulaatiotuloksien virhe on 1,17 % verrattuna mitattuihin tuloksiin. Tulevaisuudessa mallia tullaan kehittĂ€mÀÀn lisÀÀmĂ€llĂ€ siihen runkomalli ja validoimalla tĂ€ydellinen ajoneuvokokoonpano. TyöstĂ€ saatavaa tietoa voidaan hyödyntÀÀ tulevaisuuden moottorikelkkasimulaatioissa tarkan tiedon saavuttamiseksi ja nykyisellÀÀn mallia voidaan hyödyntÀÀ telastosta johtuvien ajovastusten tutkimiseen. TyössĂ€ esitellyn mallin rakennustavan pohjalta voitaisiin rakentaa telasto mihin tahansa telaâajoneuvoon ja validoida se työtĂ€ vastaavalla tavalla
Finnish Education Professionalsâ Thoughts on Adaptive Learning Technologies
With the rapidly increased use of digital technologies in education due to the COVID-19 pandemic, it is important to discuss these technologiesâ impact on the teaching profession. Using thematic analysis and epistemic network analysis (ENA), we analyzed 114 social media posts by Finnish education professionals commenting on an opinion piece about technology partly taking responsibilities usually attributed to a teacher. Out of the analyzed posts, 32 were supportive, 30 ambivalent, and 52 critical towards the presented scenario. The epistemic network analysis graphs showed some differences between posts with a different attitude. Supportive posts, on average emphasized technological capabilities and their connections with teacher workload and self-directed/self-regulated learning. In comparison, the critical posts on average emphasized human presence and its connections with pupil diversity and technological capability. Our findings both reveal the relevant themes in the discussion about technologiesâ impact on the teaching profession and underline the differences in supportive and critical argumentation.Peer reviewe
Kasvunhallinta yrityksen kasvu- ja tuotestrategioissa
TiivistelmÀ. Yritykset tavoittelevat usein liiketoiminnan kasvua keskeisenÀ tavoitteenaan. Yrityksen kasvu tuo mukanansa sisÀisiÀ kasvukipuja, jotka hidastavat tai jopa estÀvÀt yrityksen toiminnan kokonaan. Strategisen kasvunhallinnan avulla kasvuesteitÀ pyritÀÀn ennalta tunnistamaan ja hallitsemaan, jotta liiketoiminnan kannattavuus ja suorituskyky sÀilyisi.
TÀmÀn kandidaatintyön tavoitteena oli selvittÀÀ kirjallisuuskatsauksen avulla, miten kasvunhallinta nÀkyy yrityksen strategiassa ja erityisesti tuotestrategiassa. Tarkoituksena oli tunnistaa, miten liiketoiminnan kasvuun ja sen aiheuttamiin kasvukipuihin voidaan vaikuttaa yrityksen strategioiden kautta. TyössÀ pyrittiin erityisesti tunnistamaan kasvunhallinnan piirteitÀ ja strategisia tavoitteita yrityksen tuoteportfolio- ja tuotehallinnassa. LisÀksi tavoitteena oli tunnistaa yrityksen organisaation ja kasvustrategian vÀlinen yhteys.
Tutkimuksen avulla löydettiin, ettĂ€ pienet ja keskisuuret yritykset kokevat enemmĂ€n kasvukipuja sisĂ€isissĂ€ prosesseissa, mutta hyödyntĂ€vĂ€t myös vĂ€hemmĂ€n strategisen suunnittelun työkaluja niiden ehkĂ€isemisessĂ€. TĂ€mĂ€ johtuu yrittĂ€jĂ€lĂ€htöisten organisaatioiden vĂ€hĂ€isistĂ€ resursseista ja strategisen johtamistaidon puutteesta. Suuremmat organisaatiot eivĂ€t koe sisĂ€isiĂ€ kasvukipuja niin usein. Niille luontaisempaa on kohdata kilpailun ja nopeasti muuttuvien markkinaympĂ€ristöjen aiheuttamia kasvukipuja vastata vaihteleviin asiakastarpeisiin. Vastausta edellĂ€ mainittuihin kasvukipuihin haetaan usein tuotestrategian avulla joustavasta tuoteportfolio- ja tuotehallinnasta.Growth management in companyâs growth- and product strategies. Abstract. Companies are often pursuing business growth as their main goal. Growth can bring along internal growing pains that slow down or even fully obstruct the companiesâ activities. Strategic growth management is used to identify and manage these growth barriers, in forward to maintain the profitability and efficiency.
This bachelorâs thesisâ goal was to find out, how growth management is seen in companyâs strategy and especially in product strategy by using literature review. The purpose was to identify how growing pains can be influenced with strategies. This work tried to especially recognize growth management characteristics and strategic goals in companyâs product portfolio management and product management. In addition, the goal was also to identify the relationship between organization and growth strategy.
The research resulted that small and middle-sized companies experience more internal growing pains and utilize strategic tools to prevent them less than larger organizations. This is due to their lack of resources and poor skills in strategic management. Larger businesses tend to face more growing pains concerning competitive environment and rapidly changing customer needs. This is often resolved by exploiting product strategy to maintain flexible product portfolio management and product management
