Polarímetro virtual: desenvolvimento, utilização e avaliação de um software educacional

Optical activity is the ability of chiral substances to rotate the plane of plane-polarized light and is measured using an instrument called a polarimeter. An educational software application to explore, both interactively and visually, the concepts related to polarimetry to facilitate their understanding was developed. The software was field-tested and a questionnaire evaluating the graphics interface, usability and the software as an educational tool, was answered by students. The results characterized the computer application developed as an auxiliary tool for assisting teachers in lectures and students in the learning process.

Ressonância: desenvolvimento, utilização e avaliação de um software educacional

Resonance is a useful concept that shows how electrons are shared between two or more atoms and allows a prediction of the chemical reactivity and relative stability of reagents, intermediates, and products. An educational software that enables interactive exploration of the concepts related to resonance and thereby facilitates its understanding was developed. The software was field-tested, and an evaluation questionnaire concerning the software as an educational tool was answered by the students and professors involved in the test. The results led to the conclusion that the developed computer application can be characterized as an auxiliary tool that assists teachers in their lectures and students in their learning process.

INTERACTIONS: DESIGN, IMPLEMENTATION AND EVALUATION OF A COMPUTATIONAL TOOL FOR TEACHING INTERMOLECULAR FORCES IN HIGHER EDUCATION

Intermolecular forces are a useful concept that can explain the attraction between particulate matter as well as numerous phenomena in our lives such as viscosity, solubility, drug interactions, and dyeing of fibers. However, studies show that students have difficulty understanding this important concept, which has led us to develop a free educational software in English and Portuguese. The software can be used interactively by teachers and students, thus facilitating better understanding. Professors and students, both graduate and undergraduate, were questioned about the software quality and its intuitiveness of use, facility of navigation, and pedagogical application using a Likert scale. The results led to the conclusion that the developed computer application can be characterized as an auxiliary tool to assist teachers in their lectures and students in their learning process of intermolecular forces.

BLOGS NO ENSINO DE QUÍMICA: ANÁLISE DE COMENTÁRIOS PUBLICADOS EM DISCIPLINA DE COMUNICAÇÃO CIENTÍFICA

Blogs and other technology tools are commonly used in our society. Although we are familiar with the use of technology for social interaction, its application in the classroom environment is still not fully appreciated by the teaching community as a useful learning tool. This paper sheds light on this use by presenting the analysis of the comments posted on a blog used by undergraduate chemistry students for a scientific communication undergraduate course. On the course, students used the blog to ask questions and discuss assignments. All the comments were monitored by the professor and her teaching assistant, who also posted their comments. We analyzed the content of these comments using the model proposed by Henri and adapted by McKenzie and Murphy. The results show a predominance of administrative comments, followed by course content comments. The findings also indicated that this tool complements classroom discussions, supports the participation of students who would otherwise not take part, and allows a continuous learning process for all the students. We concluded that the use of blogs improved the classroom experience and supported the instructional classroom activities.

Hållpunkter för lärande : småbarns möten

Developed from human activities, mathematical knowledge is bound to the world and cultures that men and women experience. One can say that mathematics is rooted in humans’ everyday life, an environment where people reach agreement regarding certain “laws” and principles in mathematics. Through interaction with worldly phenomena and people, children will always gain experience that they can then in turn use to understand future situations. Consequently, the environment in which a child grows up plays an important role in what that child experiences and what possibilities for learning that child has. Variation theory, a branch of phenomenographical research, defines human learning as changes in understanding and acting towards a specific phenomenon. Variation theory implies a focus on that which it is possible to learn in a specific learning situation, since only a limited number of critical aspects of a phenomenon can be simultaneously discerned and focused on. The aim of this study is to discern how toddlers experience and learn mathematics in a daycare environment. The study focuses on what toddlers experience, how their learning experience is formed, and how toddlers use their understanding to master their environment. Twenty-three children were observed videographically during everyday activities. The videographic methodology aims to describe and interpret human actions in natural settings. The children are aged from 1 year, 1 month to 3 years, 9 months. Descriptions of the toddlers’ actions and communication with other children and adults are analyzed phenomenographically in order to discover how the children come to understand the different aspects of mathematics they encounter. The study’s analysis reveals that toddlers encounter various mathematical concepts, similarities and differences, and the relationship between parts and whole. Children form their understanding of such aspects in interaction with other children and adults in their everyday life. The results also show that for a certain type of learning to occur, some critical conditions must exist. Variation, simultaneity, reasonableness and fixed points are critical conditions of learning that appear to be important for toddlers’ learning. These four critical conditions are integral parts of the learning process. How children understand mathematics influences how they use mathematics as a tool to master their surrounding world. The results of the study’s analysis of how children use their understanding of mathematics shows that children use mathematics to uphold societal rules, to describe their surrounding world, and as a tool for problem solving. Accordingly, mathematics can be considered a very important phenomenon that children should come into contact with in different ways and which needs to be recognized as a necessary part of children’s everyday life. Adults working with young children play an important role in setting perimeters for children’s experiences and possibilities to explore mathematical concepts and phenomena. Therefore, this study is significant as regards understanding how children learn mathematics through everyday activities.

Parallella, dynamiska representationer i gymnasiefysiken : implementering av ett interaktivt datorverktyg i didaktiska situationer och uppfattning av effektivt lärande

The computer is a useful tool in the teaching of upper secondary school physics, and should not have a subordinate role in students' learning process. However, computers and computer-based tools are often not available when they could serve their purpose best in the ongoing teaching. Another problem is the fact that commercially available tools are not usable in the way the teacher wants. The aim of this thesis was to try out a novel teaching scenario in a complicated subject in physics, electrodynamics. The didactic engineering of the thesis consisted of developing a computer-based simulation and training material, implementing the tool in physics teaching and investigating its effectiveness in the learning process. The design-based research method, didactic engineering (Artigue, 1994), which is based on the theoryof didactical situations (Brousseau, 1997), was used as a frame of reference for the design of this type of teaching product. In designing the simulation tool a general spreadsheet program was used. The design was based on parallel, dynamic representations of the physics behind the function of an AC series circuit in both graphical and numerical form. The tool, which was furnished with possibilities to control the representations in an interactive way, was hypothesized to activate the students and promote the effectiveness of their learning. An effect variable was constructed in order to measure the students' and teachers' conceptions of learning effectiveness. The empirical study was twofold. Twelve physics students, who attended a course in electrodynamics in an upper secondary school, participated in a class experiment with the computer-based tool implemented in three modes of didactical situations: practice, concept introduction and assessment. The main goal of the didactical situations was to have students solve problems and study the function of AC series circuits, taking responsibility for theirown learning process. In the teacher study eighteen Swedish speaking physics teachers evaluated the didactic potential of the computer-based tool and the accompanying paper-based material without using them in their physics teaching. Quantitative and qualitative data were collected using questionnaires, observations and interviews. The result of the studies showed that both the group of students and the teachers had generally positive conceptions of learning effectiveness. The students' conceptions were more positive in the practice situation than in the concept introduction situation, a setting that was more explorative. However, it turned out that the students' conceptions were also positive in the more complex assessment situation. This had not been hypothesized. A deeper analysis of data from observations and interviews showed that one of the students in each pair was more active than the other, taking more initiative and more responsibilityfor the student-student and student-computer interaction. These active studentshad strong, positive conceptions of learning effectiveness in each of the threedidactical situations. The group of less active students had a weak but positive conception in the first iv two situations, but a negative conception in the assessment situation, thus corroborating the hypothesis ad hoc. The teacher study revealed that computers were seldom used in physics teaching and that computer programs were in short supply. The use of a computer was considered time-consuming. As long as physics teaching with computer-based tools has to take place in special computer rooms, the use of such tools will remain limited. The affordance is enhanced when the physical dimensions as well as the performance of the computer are optimised. As a consequence, the computer then becomes a real learning tool for each pair of students, smoothly integrated into the ongoing teaching in the same space where teaching normally takes place. With more interactive support from the teacher, the computer-based parallel, dynamic representations will be efficient in promoting the learning process of the students with focus on qualitative reasoning - an often neglected part of the learning process of the students in upper secondary school physics.

Beyond the obvious : three acts in educational drama

Researching research is not a common theme in educational drama. Nor is the educational drama process from a participant perspective a typical focus of research, at least not if the participants are disabled. Yet this is the theme of this thesis, a drama in three acts. The aim of this thesis is to describe, analyse, and discuss both the ways in which research within educational drama can be carried out and represented, and the experiences of the participants of the educational drama process. The theoretical framework that steers the research process is built up of two pairs of frames, each of them, like Russian nesting dolls, containing further frames. The first frame, relating to the outcomes of conducting research in educational drama, comprises philosophical, representational, and personal theories. As the second question asks what educational drama is, the subject related frame is built up of pedagogical, drama educational, and aesthetic theories. The study in its entirety follows the structure of the researcher’s hermeneutical learning process and takes the form of a journey starting from what is familiar, stretching towards what is new and different, and finally returning back to the beginning with a new view on what was there at the start. The thesis consists of two separate but related studies. The first, a familiar study conducted earlier, Alpha in Act I, was carried out among upper secondary school pupils. In the second, the new and therefore unfamiliar study, Omega in Act III, the participants are adult individuals who are physically and communicatively disabled. In between these two Acts an element of “Verfremdung” where the Alpha study is systematically scrutinized as the purpose is to teach and to manage the reader to think. Meta-discussions on the philosophical issues of the study are conducted throughout the text, parallel to the empirical parts. The outcomes of the first research question show that philosophical, methodical, and representational consistency is crucial for research. While this may sound like stating the obvious, this has nevertheless not always been considered fact, especially not within qualitative research. The outcomes further stress that representational issues are also to be recognized when presenting non-rational aspects of educational drama. By wording the world, through the use of visualising language, the surplus of meanings of educational drama can be, as they are within this study, made visible, sensible, and almost tangible, not only cognitively understandable. The outcomes of the second question point to the different foci of the studies, with Alpha focusing on the rationally retold experiences and Omega focusing on nonrational experiences. The outcomes expose educational drama as a learning process comprising doing, reflecting, and being. The doing aspect communicates the concrete efforts in creating a piece of theatre, while the being aspect relates experiences of being as situated, embodied and sensuous, reciprocal, empowering, aesthetic and artistic, and existential. Reflection is the twine that runs throughout the process and connects both doing and being. In summary, the outcomes could be formulated as “learning from learning how to make theatre”.

Epistemological anarchism of Paul Karl Feyerabend and medical education

The thoughts of the philosopher Paul Karl Feyerabend brought important contributions to the debate on Science in the 20th century. Most recently his views about non-existence of a single method for doing science have been employed to rethink science education and propose the use of multiple methods for effective teaching-learning process. This article employs the theoretical framework of the author expressed in the book Against Method, 1977, about the epistemological anarchism and the methodological pluralism and uses it in the contemporary discussion of medical education.

Resa i röstens landskap : en narrativ studie av hur lärare blir professionella röstanvändare

The theme of this thesis is the learning process that occurs when teachers become professional voice users. The aim is to explore what it (really) means to become a professional voice user in a teaching profession; thereby developing an understanding of how future education in this field can be arranged so as to both effectively prevent vocal problems and to develop oral didactical competence among teachers. The ambition is to describe, interpret, and understand the learning process through a combination of emic and ethic research perspectives. The theoretical frame of reference reflects the cross disciplinary character of the thesis. Voice problems are common among both student teachers and inservice teachers and adversely affect professional competence, identity and quality of life. Additionally, vocal problems are proven to have a negative impact on pupils´ learning. The individual elements of learning are explored in the light of experiential learning theory and transformative learning theory. The social elements of learning are explored in relation to the theory of situated learning. In addition, theories of teacher professionalisation in terms of competence and identity are outlined. The empirical study has a longitudinal and multi method character. It is anchored in a phenomenological hermeneutical tradition, more specifically in narrative inquiry. The point of departure is the learning experiences of ten student teachers, who attended a ten week long course on voice production as part of their teacher training at Åbo Akademi University, in the autumn of 2002 and the spring of 2003. Four interviews in the form of conversations were conducted with each participant. These were crystallised with a process diary, a Swedish Voice Handicap Index, a voice observation, and a video observation. A fifth interview was conducted with each participant five years post teacher training, in the spring of 2008. Participant observation was also conducted throughout the course. The research materials have been analysed and interpreted narratively using a phenomenological hermeneutical method. The results are presented descriptively as individual narratives, which are reflected in logopedic research materials. Learning is here understood as emergent awareness. This is followed by a meta narrative concerning learning as experiences in the four dimensions body, thought, feeling, and relation. Finally, interpretation is expressed with respect to the theory of relational education. Learning is here understood as a movement in the field between the actual and the possible voice. It is also viewed as fundamentally rooted in inter-human relationships, in moments of presence and coexistence. As a tentative answer to the call for an existential space for learning in order to be a professional voice user, I suggest the concept of a learning refuge as a locus for a learning process built on trust, mutuality and openness.

Episodes in carbohydrate chemistry : from β-linked mannosides to glycoconjugates

Carbohydrates are one of the most abundant classes of biomolecules on earth. In the initial stages of research on carbohydrates much effort was focused on investigation and determination of the structural aspects and complex nature of individual monosaccharides. Later on, development of protective group strategies and methods for oligosaccharide synthesis became the main topics of research. Today, the methodologies developed early on are being utilized in the production of carbohydrates for biological screening events. This multidisciplinary approach has generated the new discipline of glycobiology which focuses on research related to the appearance and biological significance of carbohydrates. In more detail, studies in glycobiology have revealed the essential roles of carbohydrates in cell-cell interactions, biological recognition events, protein folding, cell growth and tumor cell metastasis. As a result of these studies, carbohydrate derived diagnostic and therapeutic agents are likely to be of growing interest in the future. In this doctoral thesis, a journey through the fundamentals of carbohydrate synthesis is presented. The research conducted on this journey was neither limited to the study of any particular phenomena nor to the addressing of a single synthetic challenge. Instead, the focus was deliberately shifted from time to time in order to broaden the scope of the thesis, to continue the learning process and to explore new areas of carbohydrate research. Throughout the work, several previously reported synthetic protocols, especially procedures related to glycosylation reactions and protective group manipulations, were evaluated, modified and utilized or rejected. The synthetic molecules targeted within this thesis were either required for biological evaluations or utilized to study phenomena occuring in larger molecules. In addition, much effort was invested in the complete structural characterization of the synthesized compounds by a combination of NMR spectroscopic techniques and spectral simulations with the PERCH-software. This thesis provides the basics of working with carbohydrate chemistry. In more detail, synthetic strategies and experimental procedures for many different reactions and guidelines for the NMR-spectroscopic characterization of oligosaccharides and glycoconjugates are provided. Therefore, the thesis should prove valuable to researchers starting their own journeys in the ever expanding field of carbohydrate chemistry.

The Influence of Network Competence on Internationalization of SMEs

This study focuses on the relationship between organizational network competence and the internationalization process of small- and medium sized enterprises (SMEs). Over recent decades, the global business environment has become increasingly conducive to internationalization of small firms. A central facilitating factor in the process has been the emergence of networked business relationships between internationalizing firms. Research on SME internationalization has found that certain types of structures and dynamics of business networks allow SMEs access to the resources they need to enter foreign markets. This consequently means that their internationalization often becomes to depend on the networks they are embedded in. However, research so far has mostly ignored the possibility that the organizational ability to develop and manage business network relationships, network competence, may be a major underlying factor in determining how well SMEs can leverage their network relationships to enter foreign markets and consequently may determine in large part how successful their internationalization process turns out to be. This study aims to respond to those gaps, by empirically examining how the development of network competence in internationalizing SMEs influences the internationalization outcomes that they can expect, and how such network competence is conceptualized and developed. Using a mixed methods approach, survey data collected from 298 Finnish SMEs across five industry sectors is first used to examine how levels of network competence are related to internationalization propensity of SMEs and their subsequent international performance, growth and profitability as internationally operating firms. In order to illustrate in more detail the ways in which network competence is conceptualized and how it develops during the internationalization process of an SME, qualitative data from internationally operating Finnish SMEs are used. Longitudinal interview data of an internationalizing Finnish SME is accompanied by data gathered through a series of semistructured interviews of Finnish and Russian managers involved in mutual business relationship dyads. Structurally, this thesis examines the research issue as an article-based dissertation, consisting of five journal and conference publications. Three of these publications are based on the quantitative data, and the remaining two apply the qualitative interview data. The results find several aspects where network competence has a positive influence on the success of internationalizing SMEs, how it develops and what it entails conceptually in this context. Quantitatively, the level of network competence is found to have a positive relationship to various internationalization outcomes, including the propensity of SMEs to enter foreign markets and on their subsequent international performance, their growth and their profitability. Additionally, the positive relationship is divided between the relationship-specific and cross-relational dimension of network competence, in that the influence of the former is relevant for the propensity to internationalize, while the latter is for the growth and profitability of the already internationalized SMEs. Qualitatively, the results suggest, firstly, that the development process of network competence does not necessarily precede the start of the internationalization process, but may occur through a gradual learning process alongside it. And secondly, the results also imply that the conceptualization of network competence by Finnish managers of internationally operating Finnish SMEs is structurally distinct from that of their culturally distinct partner managers in Russia. This study contributes to the literature on SME internationalization in several ways. Firstly, it introduces operationalized organizational competencies to the literature on internationalization of SMEs, which has so far mainly examined the influence of business networking on the internationalization process without having such an organizational viewpoint. Furthermore, this study provides a multi-level analysis of the determinants of successful SME internationalization, by examining various strategic and performance outcomes across the process. These results also contribute to the literature on organizational strategy of internationalizing SMEs, by clarifying how different dimensions of business networking may be optimal in different phases of the internationalization process. Conceptually, the results of this study contribute to the literature on competence development and SME internationalization, by illustrating how the development process of network competence may occur during internationalization process. Thus, they also contribute to the discussion on how SMEs are able to influence the dynamics and structures of their business networks over time. Finally, this study contributes to the literature on the role of culture in the internationalization process, by implying that the cultural background of the manager of the SME may determine whether business networking and network competence is seen as an organizational-level or an individual level capability. The study also includes some additional contributions to the literature on dynamic capabilities in strategic management, and on that of strategic business networks. These include further clarifying the exact nature and tangibility of dynamic capabilities, and being one of the first studies to introduce constructs from both dynamic capabilities and business network literature to the field of international entrepreneurship. And finally, the study also has some contribution on the two streams of literature, in illustrating how both dyadic and network-level capabilities may be relevant, depending on the current strategic goals and market position of the firm. Keywords: network competence, internationalizatio

Sähköisen markkinoinnin markkinointisuunnitelma metallialan pk-yrityksen kansainvälistymiseen Venäjälle

Suuri osa ihmisten tiedon etsinnästä painottuu internetiin ja siellä käytettäviin hakukoneisiin. Myös yritykset ovat tiedostaneet sähköisen markkinoinnin roolin omassa kansainvälisessä näkyvyydessään. Pienyritysten kansainvälistymisessä sähköisellä markkinoinnilla voidaan parantaa markkinatiedon etsintää, asiakkaiden tavoitettavuutta ja markkinointiviestinnän kohdennettavuutta eri käyttäjäryhmille. Sähköinen markkinointi ei kuitenkaan poista kulttuurisidonnaisia epävarmuuksia, ja sen laadukas toteuttaminen vaatii perehtymistä. Tutkimuksen tavoitteena on selvittää Case-yritykselle sähköisen markkinoinnin potentiaaliset hyödyntämisvaihtoehdot kansainvälistymisprosessissa Venäjälle ja suunnitella resursseihin nähden toteutettava sähköisen markkinoinnin markkinointisuunnitelma. Monimenetelmätekniikalla toteutetussa tutkimuksessa tietolähteenä käytetään asiantuntijahaastatteluja sekä datarekistereitä. Teoriapohjana tarkastellaan pk-yrityksien tiedon vaiheittaista oppimista, verkoston roolia sekä ulkoistamispäätöksen tukena käytettyjä transaktiokustannuksia. Sähköisen markkinoinnin kehitys on ollut Venäjällä kovaa viimeisen kahden vuoden aikana. Tästä syystä venäläisten yritysten sähköisen markkinoinnin taso on osittain korkeampaa kuin suomalaisten. Sähköisellä markkinoinnilla tavoittaa erityisesti kaupungeissa asuvat ihmiset, mutta kaupunkien ulkopuolella verkkotekniikka on vielä osittain alkeellisella tasolla. Vientimuotojen vertailussa transaktiokustannusten avulla nousi esille suoran viennin malli, jossa jälleenmyyjän etsimisen avuksi kehitetään sähköisen markkinoinnin osaamista. Paikallisella jälleenmyyjällä nähdään olevan etuja sähköisen markkinoinnin, paikallistuntemuksen ja kulttuurillisten erityispiirteiden tuntemuksessa.

Suorituskyvyn mittaaminen rakennusteollisuudessa

Tutkimuksen tavoitteena oli rakentaa rakennusteollisuuteen sopiva suorituskyvyn analysointijärjestelmä. Järjestelmä on koko yrityksen kattava ja tasapainoinen. Tällöin voidaan paremmin saavuttaa yritystoiminnan perimmäinen tarkoitus eli kannattava liiketoiminta sekä taata yrityksen taloudelliset toimintaedellytykset, niin pitkällä kuin lyhyelläkin aikavälillä. Työ oli toimintatutkimus, mikä on reaalimaailmaa koskeva empiirinen tutkimus, joka konstruoi uutta todellisuutta. Toimintatutkimukselle on tyypillistä, että se suuntautuu käytäntöihin, pyrkii muutokseen ja tutkittavat osallistuvat tutkimusprosessiin. Aluksi käytiin läpi suorituskyvyn mittaamiseen liittyvää teoriaa. Sen jälkeen aloitettiin itse järjestelmän suunnittelu pohtimalla yrityksen visiota, strategiaa ja menestystekijöitä huomioiden rakennusteollisuuden erityispiirteet. Näiden pohjalta valittiin mitattavat osa-alueet sekä niihin liittyvät mittarit. Suorituskyvyn analysointijärjestelmän toteutuksen lisäksi havaittiin, että järjestelmän rakentaminen itsessään oli yritykselle erinomainen oppimisprosessi, joka avasi uusia näkökulmia sekä yrityksen toiminnan että henkilöstön kehittämiseen.

Esimies osaamisen mahdollistajana

Tämän pro gradu -tutkielman tavoitteena oli esitellä ja analysoida osaami-sen johtamista sekä tuottaa käytännön suosituksia Alko Oy:n myymälöiden lähiesimiehille heidän henkilökuntansa osaamisen kehittämiseksi. Tämän lisäksi tutkimuksessa pyrittiin kerätyn aineiston avulla luomaan ymmärrys siitä, miten osaamisen johtamiset keinot vaikuttavat asiakastyytyväisyyteen. Tutkimus toteutettiin vertailevana tapaustutkimuksena ja tutkimusaineistoa kerättiin sekä kvantitatiivisella että kvalitatiivisella tutkimusmenetelmällä. Kohdeyrityksen myyjille lähetettiin kyselylomake heidän esimiestensä osaamisen johtamisen toimista, ja kyselystä saadun tiedon syventämiseksi haastateltiin kahdeksaa myymäläpäällikköä osaamisen johtamisen teemoista. Tutkimuksen perusteella pystyttiin muodostaman käsitys siitä, mistä osaa-misen johtaminen koostuu ja miten paremman ja heikomman osaamisen omaavien myymälöiden esimiesten toimet eroavat toisistaan. Vastausten perusteella saatiin myös ymmärrys niistä osa-alueista, joita kohdeyrityksen esimiesten toiminnassa pitäisi pyrkiä kehittämään. Osaamisen kehittämisen perustan muodostavat esimiehen oma esimerkki ja oppimiseen kannustava ilmapiiri. Esimies, joka onnistuu suuntaamaan henkilökuntansa oppimisen tukemaan organisaation tavoitteita, osaa henkilökohtaistaa yhtiön strategian sopimaan jokaisen toimenkuvaan. Oppimisen tukemisessa vaaditaan esimieheltä vahvaa henkilökunnan tuntemusta, tavoitteiden asettamista ja niiden toteutumisen seurantaa. Tutkimus osoitti esimiesten olevan pääsääntöisesti innostuneita työstään ja onnistuvan osaamisen suuntaamisen toimissa hyvin. Esimiehet voisivat kehittää toimintaansa ottamalla oman henkilökuntansa mukaan toiminnan suunnitteluun ja vastuuttamalla heitä myymälän toiminnan ja oman ammattitaitonsa jatkuvaan kehittämiseen.

Virtuaalisimuloinnin käytettävyys PF-suodattimien hydraulijärjestelmien koulutuksessa, analysoinnissa ja vianmäärityksessä

Tämän työn tavoitteena oli luoda koulutusmateriaalia PF-suodattimien hydraulijärjestelmien koulutusta varten sekä selvittää Automation Studio-ohjelmiston soveltuvuutta PF-suodattimien analysointiin ja vianmääritykseen. Työssä tutkittiin myös aktivoivien koulutusmenetelmien vaikutusta oppimisprosessiin. Työn tärkeimpinä tuloksina saatiin opetusvideot PF-suodattimien hydraulijärjestelmissä käytettävistä peruskomponenteista sekä järjestelmien toimintaa kuvaavat opetusvideot. Työssä käytettyä mallinnus- ja simulointiohjelmistoa ei voida nykyisellä ohjelmaversiolla täysin soveltaa PF-suodattimien vianmääritykseen tai analysointiin. Työssä selvennettiin menestyksekkään vianmäärityksen ja analysoinnin kannalta tarvittavat laajennustarpeet ohjelmistoon. Koulutuksesta kerätyn palautteen perusteella opetusvideot yhdistettynä aktivoiviin koulutusmenetelmiin helpottavat PF-suodattimien hydraulijärjestelmien koulutusta sekä edistävät oppimisprosessia. Aktivoivia koulutusmenetelmiä voidaan pitää erityisesti soveltuvina aikuiskoulutukseen.
