Ostoreskontra –moduulin suunnittelu ja toteutus Sähkömies –taloushallinto-ohjelmistoon

Sähkömies -taloushallinto-ohjelmisto on pienille sähköalan yrityksille suunnattu valmisohjelmisto. Se on tarkoitettu tehostamaan talous- ja materiaalihallinnon tehtäviä yrityksessä. Tämän työn tavoitteena oli suunnitella ja toteuttaa ostoreskontra –moduuli Sähkömies –taloushallinto-ohjelmistoon. Ostoreskontra -ominaisuuden lisääminen ohjelmistoon on saanut alkunsa useiden asiakkaiden palautteesta saada automatisoitua yrityksen ostoreskontra -toiminto. Samalla ohjelmistosta saadaan kilpailukykyisempi tuote sähköalalla. Työssä on ensiksi tutkittu ostoreskontran yleistä toimintamallia. Ohjelmiston kehitysprosessissa on sovellettu vesiputous –ohjelmistoprosessimallia. Ostoreskontra –moduulin vaatimukset on määritelty yhdessä avainasiakkaiden kanssa. Ohjelmiston toiminnallisuuden määrittelyssä on käytetty use case –menetelmää. Vaatimusmäärittelyyn ja toiminnalliseen määrittelyyn perustuen on suunniteltu tietokantataulut, käyttöliittymälomakkeet sekä tehty ohjelmamäärittelyt. Ohjelmiston toteutukseen on käytetty Visual Basic –sovelluskehitintä sekä Access 2000 –tietokanta-ohjelmistoa.Työn lopullista onnistumista on vielä aikaista arvioida, koska ohjelmiston ostoreskontra –moduulin sisältävää versiota ei ole vielä toimitettu asiakkaille. Lupaavaa palautetta on kuitenkin tullut projektissa tiiviisti mukana olleilta asiakkailta.

Ammatti-identiteetin rakentuminen sairaanhoitajilla

Ammatti-identiteetti luo pohjan henkilön ammattitaidolle, oman, henkilökohtaisen ammatillisen osaamisen arvostamiselle sekä koko ammattikuvalle, sille millaisena työntekijänä jokainen itsensä näkee. Vahva ammatti-identiteetti aikaansaa positiivisen takaisinkytkennän, kun hyvin tehdyn työn seurauksena saadaan kannustavaa palautetta, mikä kasvattaa itsetuntoa, joka puolestaan luo positiivinen omakuvan, jonka seurauksena syntyy vahva ammatti-identiteetti. Tämän tutkimuksen tarkoituksena on selvittää millä tavoin ammatti-identiteetti rakentuu ja muotoutuu, ja millaisia ovat sitä muovaavat tekijät. Samalla pyritään selvittämään millainen merkitys ammatti-identiteetillä on työn suorittamiseen, työssä viihtymiseen sekä omaan näkemykseen itsestään tietyn alan ammattilaisena. Tutkimuksen kontekstina on terveydenhoitoala, ja empiriassa tutkitaan sairaanhoitajien ammatti-identiteettiä. Tutkimuksen perusteella näyttää siltä, että sairaanhoitajat arvostavat ammattiaan ja ammattitaitoaan huolimatta yhteiskunnallisesta aliarvostuksesta. Tämä tukee käsitystä sairaanhoitajien vahvasta ammatti-identiteetistä. Tutkimuksen tulokset osoittavat, että sairaanhoitajan ammatti-identiteetti on moniulotteinen ilmiö. Ammatti-identiteetti ei ole irrallinen henkilön persoonallisesta identiteetistä, vaan ne tukevat toinen toistaan.

Sisäinen yrittäjyys ja yksilötason motivaatio

Tutkimuksessa tarkastellaan sisäistä yrittäjyyttä ja motivaatiota yksilön näkökulmasta katsottuna. Tutkimuksen kohteena on Tapiola-ryhmän Kouvolan toimiston henkilökunta. Haastateltavina oli 10 toimihenkilöä. Tutkimuksen aineisto kerättiin puolistrukturoidulla teemahaastattelulla. Tämän kvalitatiivisin menetelmin tehdyn tutkimuksen analysointitapa on ymmärtävä. Tutkimustulokset osoittavat, että henkilökunta on vahvasti sitoutunut työn tekemiseen. Itsenäisiä tavoitteita asetetaan paljon, työstä otetaan vastuuta ja omaa työtä halutaan jatkuvasti kehittää. Näyttää siltä, että motivaatiota sisäiseen yrittäjyyteen vähentävät liian haastavat tavoitteet, usein tapahtuvat muutokset, oman päätösvallan rajallisuus sekä liian vähäinen palautteen määrä. Motivaatio sisäiseen yrittäjyyteen näyttäisi lisääntyvän jos esimerkiksi esimiehiltä tulisi useammin rakentavaa ja postiivista palautetta, sekä työtehtäviä olisi mahdollisuus vaihdella enemmän.

Practical Framework for Monitoring the Performance of Agile IT Projects in an Output-Based Outsourcing Context

Over the past decade, organizations worldwide have begun to widely adopt agile software development practices, which offer greater flexibility to frequently changing business requirements, better cost effectiveness due to minimization of waste, faster time-to-market, and closer collaboration between business and IT. At the same time, IT services are continuing to be increasingly outsourced to third parties providing the organizations with the ability to focus on their core capabilities as well as to take advantage of better demand scalability, access to specialized skills, and cost benefits. An output-based pricing model, where the customers pay directly for the functionality that was delivered rather than the effort spent, is quickly becoming a new trend in IT outsourcing allowing to transfer the risk away from the customer while at the same time offering much better incentives for the supplier to optimize processes and improve efficiency, and consequently producing a true win-win outcome. Despite the widespread adoption of both agile practices and output-based outsourcing, there is little formal research available on how the two can be effectively combined in practice. Moreover, little practical guidance exists on how companies can measure the performance of their agile projects, which are being delivered in an output-based outsourced environment. This research attempted to shed light on this issue by developing a practical project monitoring framework which may be readily applied by organizations to monitor the performance of agile projects in an output-based outsourcing context, thus taking advantage of the combined benefits of such an arrangement Modified from action research approach, this research was divided into two cycles, each consisting of the Identification, Analysis, Verification, and Conclusion phases. During Cycle 1, a list of six Key Performance Indicators (KPIs) was proposed and accepted by the professionals in the studied multinational organization, which formed the core of the proposed framework and answered the first research sub-question of what needs to be measured. In Cycle 2, a more in-depth analysis was provided for each of the suggested Key Performance Indicators including the techniques for capturing, calculating, and evaluating the information provided by each KPI. In the course of Cycle 2, the second research sub-question was answered, clarifying how the data for each KPI needed to be measured, interpreted, and acted upon. Consequently, after two incremental research cycles, the primary research question was answered describing the practical framework that may be used for monitoring the performance of agile IT projects delivered in an output-based outsourcing context. This framework was evaluated by the professionals within the context of the studied organization and received positive feedback across all four evaluation criteria set forth in this research, including the low overhead of data collection, high value of provided information, ease of understandability of the metric dashboard, and high generalizability of the proposed framework.

Asiantuntijan suorituskykyyn vaikuttavien tekijöiden mittaaminen

Tutkimuksen tavoitteena oli tutkia asiantuntijaorganisaation henkilöstön työmotivaatioon vaikuttavia tekijöitä. Konkreettisena tavoitteena oli kehittää asiantuntijaorganisaation olemassa olevaan suorituskykymittaristoon uusia mittareita, joiden avulla yrityksessä pyritään luomaan asiantuntijoille mahdollisimman motivoiva työskentelyilmapiiri. Tutkimus toteutettiin kvalitatiivisena tapaustutkimuksena. Tutkimuksen teoreettisessa osuudessa tutkittiin asiantuntijan työmotivaatioon vaikuttavia tekijöitä sekä aineettoman pääoman mittaamista. Empiirisessä osuudessa tutkittiin pienen asiantuntijaorganisaation työskentelyolosuhteita. Aineistonkeruumenetelmänä toimi vanha tutkimustieto, puolistrukturoidun haastattelun piirteitä omaavat teemahaastattelut sekä tutkijan oma havainnointi. Asiantuntijan motivaatioon vaikuttaa erityisen paljon henkilökohtainen kasvu, autonomisuus, merkityksellinen työ, haasteelliset ja vaihtelevat työtehtävät sekä työstä saatu palaute. Vähemmän merkittäviä motivaattoreita ovat raha, työsuhteen jatkuvuus, ystävälliset työtoverit, kunnioitus ja oikeudenmukainen kohtelu. Urakehitystä asiantuntija ei koe erityisen motivoivana asiana. Tutkimuksen kohdeyrityksen haasteiksi ilmeni erityisesti palautteen antaminen, osaamisen ja koulutuksen johtaminen, autonomian vähyys projektin käyttöönotto vaiheessa sekä työn kuormittavuuden jakautuminen. Uudet mittarisuoritukset kohdeyrityksessä ovat: projektipalautteen antaminen, positiivisen palautteen määrä, projektien edistymispalaverit, projektikatselmukset, suunnittelun tuntiarviot, sisäisten kehitysideoiden toteutuminen, työntekijöiden kuormituksen jakautuminen sekä koulutuksen ja osaamisen jakautuminen.

The Role of an Oncoprotein CIP2A in Breast Cancer

Cancerous inhibitor of PP2A (CIP2A) is an oncoprotein expressed in several human cancer types. Previously, CIP2A has been shown to promote proliferation of cancer cells. Mechanistically, CIP2A is known to inhibit activity of a tumor suppressor protein phosphatase 2A (PP2A) towards an oncoprotein MYC, further stabilizing MYC in human cancer. However, the molecular mechanisms how CIP2A expression is induced during cellular transformation are not well known. Also, expression, functional role and clinical relevance of CIP2A in breast cancer had not been studied before. The results of this PhD thesis work demonstrate that CIP2A is highly expressed in human breast cancer, and that high expression of CIP2A in tumors is a poor prognostic factor in a subset of breast cancer patients. CIP2A expression correlates with inactivating mutations of tumor suppressor p53 in human cancer. Notably, we demonstrate that p53 inactivation up-regulates CIP2A expression via increased expression of an oncogenic transcription factor E2F1. Moreover, CIP2A promotes expression of E2F1, and this novel positive feedback loop between E2F1 and CIP2A is demonstrated to regulate sensitivity to both p53-dependent and -independent senescence induction in breast cancer cells. Importantly, in a CIP2A deficient breast cancer mouse model, abrogation of CIP2A attenuates mammary tumor formation and progression with features of E2F1 inhibition and induction of senescence. Furthermore, we demonstrate that CIP2A expression defines the cellular response to a senescence-inducing chemotherapy in breast cancer. Taken together, these results demonstrate that CIP2A is an essential promoter of breast cancer tumor growth by inhibiting senescence. Finally, this study implicates inhibition of CIP2A as a promising therapy target for breast cancer.

Julkisen organisaation johdon raportoinnin kehittäminen CASE: Puolustusvoimien johtamisjärjestelmäkeskus

Tämän tutkielman tavoitteena on tutkia julkisen organisaation sisäistä taloudellista raportointia eli johdon raportointia case -organisaation avulla. Tavoitteena on kehittää ja uudistaa organisaation johdolle tuotettavaa kustannusseurantaan liittyvää raportointityökalua. Teoreettista viitekehystä luodaan pääasiassa New Public Management (NPM) -ajattelua tutkimalla. Teoriaosuudessa pohditaan myös muita julkisen organisaation johtamiseen ja raportointiin liittyviä asioita: tulosjohtamista ja suorituskyvyn mittaamista. Empiria osuudessa kehitetään tutkitun teorian, organisaation sisällä kahdessa eri vaiheessa tehtyjen haastattelujen ja jatkuvan havainnoinnin avulla uusi raportointityökalu johdolle. Tämän kehitystyön tuloksena case -organisaatiossa otettiin vuoden 2015 alussa käyttöön uudistettu johdon raportti resurssien käytöstä. Raportti sai paljon positiivista palautetta sen käyttäjiltä ja sen todettiin helpottavan kustannusseurantaa. Seurannan toteutus ja sen taustojen ymmärtäminen vaatii kuitenkin vielä paljon opettelua organisaatiossa.

Quality of radiotherapy care by development of e-feedback knowledge

The aim of this three phase study was to develop quality of radiotherapy care by the e-Feedback knowledge of radiotherapy -intervention (e-Re-Know). In Phase I, the purpose was to describe the quality of radiotherapy care and its deficits experienced by cancer patients. Based on the deficits in patient education in Phase II, the purpose was to describe cancer patients’ e-knowledge expectations in radiotherapy. In Phase III, the purpose was to develop and evaluate the outcomes of the e-Re-Know among breast cancer patients. The ultimate aim was to develop radiotherapy care to support patients’ empowerment with patient e-education. In Phase I (2004-2005), the descriptive design was used, and 134 radiotherapy patients evaluated their experiences by Good Nursing Care Scale for Patients (GNCS-P) in the middle of RT period. In Phase II (2006-2008), the descriptive longitudinal design was used and 100 radiotherapy patients’ e-knowledge expectations of RT were evaluated using open-ended questionnaire developed for this study before commencing first RT, in the middle of the treatment, and concluding RT period. In Phase III, firstly (2009-2010), the e-Re-Know intervention, i.e. knowledge test and feedback, was developed in terms of empowering knowledge and implemented with e-feedback approach based on literature and expert reviews. Secondly (2011-2014), the randomized controlled study was used to evaluate the e-Re-Know. Breast cancer patients randomized to either the intervention group (n=65) receiving the e-Re-Know by e-mail before commencing first RT and standard education or the control group (n=63) receiving standard education. The data were collected before commencing first RT, concluding last RT and 3 months after last RT using RT Knowledge Test, Spielberger’s State Trait Inventory (STAI) and Functional Assessment of Cancer Therapy - Breast (FACT-B) –instruments. Data were analyzed using statistical methods and content analysis. The study showed radiotherapy patients experienced quality of care high. However, there were deficits in patient education. Furthermore, radiotherapy patients’ multidimensional e-knowledge expectations through Internet covered mainly bio-physiological and functional knowledge. Thus, the e-Re-Know was developed and evaluated. The study showed when breast cancer patients’ carried out the e-Re-Know their knowledge of side effects self-care was significantly increased and quality of life (QOL) significantly improved in line with decrease in anxiety from time before radiotherapy period to three months after. In addition, the e-Re-Know has potential to have positive effects on anxiety and QOL, regardless of patient characteristics or knowledge level. The results support the theory of empowering patient education suggesting that empowerment can be supported by confirming patients’ understanding of own knowledge level. In summary, the e-Feedback knowledge of radiotherapy (e-Re-Know) intervention can be recommended in development of quality of radiotherapy care experienced by breast cancer patients. Further research is needed to assess and develop patient-centred quality of care by patient education among cancer patients.

Vuorovaikutuskouluttajana työyhteisöissä

This thesis concerns organizing a workshop about interaction in the various communities represented by Helsinki city's social welfare department. There were seventeen workshops altogether and they were organized in different communities; for example, in a children's daycare centre. The aim was to gain experience in the planning and organizing of these kinds of workshop. The workshops focused on dealing with interactive quetions arising out of the very community which was taking part in the workshop. These questions were discussed and handled using a technique called forum-statues. This means that the problems arising from the community were presented as living pictures to the group. There was also a short theoretical element concerning interactions between people, self-esteem, the different phases in developing a group, and the effects of conflicts in groups. There was a high degree of interest in the research and places were soon filled. The workshops consisted of a warming part with a lot of playing, a deepening part with questions arising out of the group, and a relaxation and feedback part at the end. The basis of the workshop was similar for all seventeen workshops. The athmosphere in workshops was discussive and open. The participants were engouraged to express there opinions and point of views. Feedback from the participantswas very positive. The participants obtained new points of view, according there fellow workers, and the community spirit improved. Shortage of time was, unfortunately, a problem. With more time, it would have been possible to go deeper into the problems of interaction within the community. Ceratinly, the research proved that there would be great demand for this kind of workshop in future.

Expertise and decision making among clinicians in investigations of alleged child sexual abuse

The purpose of the present thesis was to explore different aspects of decision making and expertise in investigations of child sexual abuse (CSA) and subsequently shed some light on the reasons for shortcomings in the investigation processes. Clinicians’ subjective attitudes as well as scientifically based knowledge concerning CSA, CSA investigation and interviewing were explored. Furthermore the clinicians’ own view on their expertise and what enhances this expertise was investigated. Also, the effects of scientific knowledge, experience and attitudes on the decision making in a case of CSA were explored. Finally, the effects of different kinds of feedback as well as experience on the ability to evaluate CSA in the light of children’s behavior and base rates were investigated. Both explorative and experimental methods were used. The purpose of Study I was to investigate whether clinicians investigating child sexual abuse (CSA) rely more on scientific knowledge or on clinical experience when evaluating their own expertise. Another goal was to check what kind of beliefs the clinicians held. The connections between these different factors were investigated. A questionnaire covering items concerning demographic data, experience, knowledge about CSA, selfevaluated expertise and beliefs about CSA was given to social workers, child psychiatrists and psychologists working with children. The results showed that the clinicians relied more on their clinical experience than on scientific knowledge when evaluating their expertise as investigators of CSA. Furthermore, social workers possessed stronger attitudes in favor of children than the other groups, while child psychiatrists had more negative attitudes towards the criminal justice system. Male participants held less strong beliefs than female participants. The findings indicate that the education of CSA investigators should focus more on theoretical knowledge and decision making processes as well as the role of beliefs In Study II school and family counseling psychologists completed a Child Sexual Abuse Attitude and Belief Scale. Four CSA related attitude and belief subscales were identified: 1. The Disclosure subscale reflecting favoring a disclosure at any cost, 2. The Pro-Child subscale reflecting unconditional belief in children's reports, 3. The Intuition subscale reflecting favoring an intuitive approach to CSA investigations, and 4. The Anti Criminal Justice System subscale reflecting negative attitudes towards the legal system. Beliefs that were erroneous according to empirical research were analyzed separately. The results suggest that some psychologists hold extreme attitudes and many erroneous beliefs related to CSA. Some misconceptions are common. Female participants tended to hold stronger attitudes than male participants. The more training in interviewing children the participants have, the more erroneous beliefs and stronger attitudes they hold. Experience did not affect attitudes and beliefs. In Study III mental health professionals’ sensitivity to suggestive interviewing in CSA cases was explored. Furthermore, the effects of attitudes and beliefs related to CSA and experience with CSA investigations on the sensitivity to suggestive influences in the interview were investigated. Also, the effect of base rate estimates of CSA on decisions was examined. A questionnaire covering items concerning demographic data, different aspects of clinical experience, self-evaluated expertise, beliefs and knowledge about CSA and a set of ambiguous material based on real trial documents concerning an alleged CSA case was given to child mental health professionals. The experiment was based on a 2 x 2 x 2 x 2 (leading questions: yes vs no) x (stereotype induction: yes vs no) x (emotional tone: pressure to respond vs no pressure to respond) x (threats and rewards: yes vs no) between-subjects factorial design, in which the suggestiveness of the methods with which the responses of the child were obtained were varied. There was an additional condition in which the material did not contain any interview transcripts. The results showed that clinicians are sensitive only to the presence of leading questions but not to the presence of other suggestive techniques. Furthermore, the clinicians were not sensitive to the possibility that suggestive techniques could have been used when no interview transcripts had been included in the trial material. Experience had an effect on the sensitivity of the clinicians only regarding leading questions. Strong beliefs related to CSA lessened the sensitivity to leading questions. Those showing strong beliefs on the belief scales used in this study were even more prone to prosecute than other participants when other suggestive influences than leading questions were present. Controversy exists regarding effects of experience and feedback on clinical decision making. In Study IV the impact of the number of handled cases and of feedback on the decisions in cases of alleged CSA was investigated. One-hundred vignettes describing cases of suspected CSA were given to students with no experience with investigating CSA. The vignettes were based on statistical data about symptoms and prevalence of CSA. According to the theoretical likelihood of CSA the children described were categorized as abused or not abused. The participants were asked to decide whether abuse had occurred. They were divided into 4 groups: one received feedback on whether their decision was right or wrong, one received information about cognitive processes involved in decision making, one received both, and one did not receive feedback at all. The results showed that participants who received feedback on their performance made more correct positive decisions and participants who got information about decision making processes made more correct negative decisions. Feedback and information combined decreased the number of correct positive decisions but increased the number of correct negative decisions. The number of read cases had in itself a positive effect on correct positive decision.

Henkilöstön motivoituminen muutoksessa. Case: Asumisen rahoitus ja kehittämiskeskus

Tämän tutkimuksen tarkoituksena on ymmärtää henkilöstön motivoitumiseen vaikuttavia tekijöitä muutostilanteessa ja tunnistaa muutosjohtamisen kehittämiskohteita. Tutkielma on laadullinen tutkimus, jonka sekundaariaineistona käytetään ARAn työtyytyväisyystutkimuksia vuosilta 2007 ja 2008. Primääriaineiston muodostavat tutkimuksen kohdeorganisaation kolmentoista henkilön teemahaastattelut. Tutkimuksen perusteella voidaan todeta, että henkilöstön motivoitumiseen vaikuttaa työtehtävien mielekkyys, työyhteisöltä ja asiakkailta saatava palaute, työn arvostus ja toimiva yhteistyö. Henkilöstöpoliittiset toimenpiteet tukevat yksilöä muutoksessa. Muutosjohtamisen kehittämiskohteena on viestittää henkilöstölle muutoksen tarpeellisuus ja sen vaikutukset, toteuttaa muutos hallitusti sekä luoda muutokselle positiivinen ilmapiiri.

Psykologinen omistajuus etätyöskentelyssä

Tämän tutkimuksen tavoitteena oli kuvata ja selittää etätyöntekijöiden työhönsä kokemaa omistajuuden tunnetta sekä sen syntymismekanismeja ja seurauksia. Lisäksi tavoitteena oli selvittää kuinka etätyön eri muodot korostuvat etätyöskentelyn oletetuissa eduissa ja ongelmissa. Etätyön muotojen osalta oli tavoitteena myös selvittää niden yhteyttä itsenäisyyden tunteeseen. Tutkielman tutkimusmenetelmä on kvantitatiivinen ja määrällistä aineistoa analysoitiin SPSS-ohjelmiston avulla. Tutkielman tutkimuskontekstina on etätyö. Tutkimuksen perusteella etätyöntekijät kokevat työnsä keskimäärin melko paljon omakseen. Tutkimustulokset osoittivat, että työtä kohtaan koettu psykologinen omistajuus syntyy kolmen ”reitin” kautta, joita ovat kohteen hallinta, kohteen perusteellinen tunteminen ja voimavarojen käyttäminen kohteeseen. Näiden ”reittien” syntymiseen taas oli positiivinen yhteys seuraavilla työn ulottuvuuksilla: työn vaatimat taidot, työn hahmottaminen, työn merkitsevyys, itsenäisyys sekä palaute työstä. Tutkimustulokset todistivat, että psykologinen omistajuus oli positiivisessa yhdeydessä työperäiseen itsetuntoon, työtyytyväisyyteen, työmotivaatioon, yksilön kehittymiseen työssään, vastuuntuntoon työtään kohtaan sekä rehtiyteen. Voimakkain yhteys psykologisella omistajuudella oli työtyytyväisyyden kanssa. Tutkimuksen perusteella voidaankin sanoa, että mitä enemmän henkilö kokee työnsä omakseen, niin sitä tyytyväisempi hän on työhönsä. Tutkimustulokset osoittivat, että etätyön muodolla on merkitystä etätyöskentelyssä koettuihin etuihin ja ongelmiin. Täysipäiväisen etätyön tekijät kokivat edut kaikista positiivisimmin ja ongelmat taas kaikista negatiivisimmin. Mobiilit työntekijät kokivat työssään alhaisempaa itsenäisyyden tunnetta kuin muiden etätyön muotojen edustajat.

Muutosprosessin implementointi ja johtaminen terveydenhuollon välityspalveluissa

The aim of this study was to produce information on the implementation of the change process made according to the Kotter’s change model in HUSServis call operator services and to understand the success of the change process experienced by the call operators and the team leaders. The study was a qualitative case study. The research methods used were the researcher’s own participatory observation and the electronic survey. The survey was conducted by e-mail, using Webropol - software. The target group consisted of 32 persons, in which 29 were call operators and 3 were team leaders. The results of the study showed that the implementation of the change process made according to the Kotter’s change model was experienced successfully. The change was influenced by the successful selection of persons to the guiding coalition and an assertive leadership, in which the trust was enhanced in a research organization by increasing communication and feedback. This influence had a great positive change on the working environment. It also had a clear impact on the willingness of the personnel to be involved in change, which led to a clear improvement on the customer services.

Promoting Programming Learning. Engagement, Automatic Assessment with Immediate Feedback in Visualizations

The skill of programming is a key asset for every computer science student. Many studies have shown that this is a hard skill to learn and the outcomes of programming courses have often been substandard. Thus, a range of methods and tools have been developed to assist students’ learning processes. One of the biggest fields in computer science education is the use of visualizations as a learning aid and many visualization based tools have been developed to aid the learning process during last few decades. Studies conducted in this thesis focus on two different visualizationbased tools TRAKLA2 and ViLLE. This thesis includes results from multiple empirical studies about what kind of effects the introduction and usage of these tools have on students’ opinions and performance, and what kind of implications there are from a teacher’s point of view. The results from studies in this thesis show that students preferred to do web-based exercises, and felt that those exercises contributed to their learning. The usage of the tool motivated students to work harder during their course, which was shown in overall course performance and drop-out statistics. We have also shown that visualization-based tools can be used to enhance the learning process, and one of the key factors is the higher and active level of engagement (see. Engagement Taxonomy by Naps et al., 2002). The automatic grading accompanied with immediate feedback helps students to overcome obstacles during the learning process, and to grasp the key element in the learning task. These kinds of tools can help us to cope with the fact that many programming courses are overcrowded with limited teaching resources. These tools allows us to tackle this problem by utilizing automatic assessment in exercises that are most suitable to be done in the web (like tracing and simulation) since its supports students’ independent learning regardless of time and place. In summary, we can use our course’s resources more efficiently to increase the quality of the learning experience of the students and the teaching experience of the teacher, and even increase performance of the students. There are also methodological results from this thesis which contribute to developing insight into the conduct of empirical evaluations of new tools or techniques. When we evaluate a new tool, especially one accompanied with visualization, we need to give a proper introduction to it and to the graphical notation used by tool. The standard procedure should also include capturing the screen with audio to confirm that the participants of the experiment are doing what they are supposed to do. By taken such measures in the study of the learning impact of visualization support for learning, we can avoid drawing false conclusion from our experiments. As computer science educators, we face two important challenges. Firstly, we need to start to deliver the message in our own institution and all over the world about the new – scientifically proven – innovations in teaching like TRAKLA2 and ViLLE. Secondly, we have the relevant experience of conducting teaching related experiment, and thus we can support our colleagues to learn essential know-how of the research based improvement of their teaching. This change can transform academic teaching into publications and by utilizing this approach we can significantly increase the adoption of the new tools and techniques, and overall increase the knowledge of best-practices. In future, we need to combine our forces and tackle these universal and common problems together by creating multi-national and multiinstitutional research projects. We need to create a community and a platform in which we can share these best practices and at the same time conduct multi-national research projects easily.
