Tutkimuksen tavoitteena oli analysoida, miten suomalaiset kauppatieteelliset yksiköt tarjoavat eettisyyden koulutusta. Erityisesti tutkimuksessa keskityttiin laskentatoimen pääaineen opiskelijoille kohdistettuun eettisyyden koulutukseen. Tutkimuksen teoreettinen viitekehys rakentui sekä eettisyyden koulutusta että eettisyyden ja liike-elämän välistä suhdetta yleisesti käsittelevään tutkimukseen. Empiirisen aineiston keräämiseen sovellettiin kyselytutkimusta, joka lähetettiin kaikille suomalaisen yliopiston tai korkeakoulun palveluksessa oleville laskentatoimen professoreille, lehtoreille, yliassistenteille sekä assistenteille. Kyselytutkimuksen tulokset osoittivat eettisyyden olevan osa jokaisen suomalaisen laskentatoimea opettavan kauppatieteellisen yksikön kurssitarjontaa. Vain neljä yksikköä tarjosi tutkimuksen tulosten mukaan erillistä, eettisyyteen tai yhteiskuntavastuuseen keskittyvää opetusta. Valtaosa opetti eettisyyttä osana muuta kauppatieteiden opetusta. Pääosa suomalaisista laskentatoimen opettajista piti tutkimuksen tulosten mukaan eettisyyden koulutusta joko erittäin tärkeänä tai melko tärkeänä osana laskentatoimen koulutusta.

The social activity of nurse teacher – a part of teacherhood Every nurse teacher must know the current health policy in order to use it in teaching. The conception of the role of health policy in curriculum and the concrete teaching of social activity are quite unclear. The purpose of this study was to describe the social activity of nurse teachers. The data were collected by a structured questionnaire (Paltta 1998) via E-mail. The questionnaire included background factors and nine items for society activities. The respondents were nurse teachers, teachers for emergency nursing, public health nurse and midwifery teachers from all polytechnics in Finland. Response rate was 46 % (n = 342). The data were analysed by using descriptive statistics. The results of this study showed that 36 % of nurse teachers evaluated themselves quite active in society activities and 43 % of them evaluated themselves inactive. 32 % of nurse teachers was member and involved to working in general organisations. 28 % of nurse teachers worked or have been worked in local commission or trustees. Nurse teachers evaluated their knowledge about health policy quite good (mean 3.75, Std 0.99). Their knowledge about education policy was also quite good (mean 3.57, Std 1.04). Nurse teachers updated their knowledge about health policy and education policy by reading professional journals, newspapers, internet and following television and radio. According to results nurse teachers are quite active in society activities even tough almost half of them evaluated themselves quite inactive. Although nurse teachers’ knowledge about health policy was quite good by their opinion, they must update and improve the knowledge. In the future it is important to study how nurse teachers use health policy in their teaching and how nurse students’ participation in society activities can be improved.

Ethical problems occurring during the practical training period of Finnish nursing students The present study focused on nursing students adopting the professional code of conduct during their supervised practical training. The study was carried out in two phases. During the first phase, the objective was to survey ethical problems occurring in practical training as well as how these problems are detected and resolved by nursing students and their supervisors at different stages of their studies. In the second phase, the capability of the nursing students about to graduate to detect and resolve ethical problems was described and analyzed. The students’ capacity for self-instruction, independent search for information as well as factors related to teaching of ethics were determined within this phase. Further, an extensive literature review was carried out to complement the study. Thus, the main objective of the thesis was to make suggestions for the development of the teaching of ethics and supervision in nursing studies and in practice. In the first part of the empirical phase (2002–2005), the views of the nursing students (n =18) were clarified with themed open essay questions. Furthermore, the views of the supervising nurses (n = 115) were established by utilizing a series of themed questions and group interviews. During the second phase (2006–2007), the data for the analyses were collected from nursing students in their graduating stage (n = 319) by a national Internet-based questionnaire. The results of the first phase were examined with contentanalysis and those of the second phase both statistically and by using content analysis. Ethical problems occurring during supervised practical training were typically connected to a patient or a client, a member of the nursing staff or to a student, while solutions were connected to preparation and the action to solve the problem in question. Ethical dilemmas were classified as legal, ethical comportment and uncertainty problems as well as personal and institutional ones. The solutions for these problems were further grouped as based on facts, instructor/staff/member/specialist or patient/client/relative. The results showed that although the nursing students about to graduate had detected many ethical problems both independently as well as together with the nursing staff during every practical training period, they were able to resolve only few of them. Ethical problems were most frequently encountered during training in psychiatric nursing. On the grounds of their own impressions, the nursing students stated that their ability to detect and solve ethical problems improved during their training period. The primary factors related to this enhancement of their skills were teaching and the students’ readiness for selfinstruction. Gender, orientation of the studies and age were observed to be the most important among the underlying factors influencing the capability to detect and solve ethical problems as well as to engage in self-instruction. Based on the results obtained, suggestions for development as well as topics for further studies are presented through teaching of professional ethics and supervision during practical training.

Tavoitteeni tässä tutkimuksessa oli selvittää, miten kirjallisuustieteellisiä proosa-anayysin käsitteitä opetetaan opetussuunnitelman mukaisissa lukion äidinkielen ja kirjallisuuden oppikirjoissa ja miten hyvin kokelaat hallitsivat kertoja-käsitteen tekstitaidon ylioppilaskokeessa keväällä 2007. Samalla pohdin, minkälainen kirjallisuustieteellinen käsitteistö palvelisi tekstianalyysin opetusta koulussa, koska Lukion opetussuunnitelman perusteet 2003 ja äidinkielen ylioppilaskoe edellyttävät äidinkielen ja kirjallisuuden opetukselta ja oppilailta käsitteiden käyttöä. Tutkimusaineistonani olivat kaikki kuusi käytössä olevaa lukion äidinkielen ja kirjallisuuden oppikirjaa ja 440 kpl kevään 2007 äidinkielen tekstitaidon ylioppilaskokeen vastaustekstiä. Oppikirjoja tarkastelin soveltamalla niiden arviointiin Lev S. Vygotskin ajatuksia arkikäsitteiden ja tieteellisten käsitteiden opettamisesta ja Hans Aeblin esittämiä teoreettisia malleja käsitteiden opettamisesta ja oppimisesta. Tutkimukseni osoittaa, että opetussuunnitelmassa mainittujen proosa-analyysin käsitteiden kertoja, näkökulma, motiivi, aihe ja teema opetus on epätäsmällistä. Oppikirjoissa ei ole otettu huomioon sitä, että käsitteenoppiminen on monivaiheinen prosessi. Myöskään problematiikkaa, joka aiheutuu kyseisten käsitteiden määrittelyn kirjavuudesta ja käytöstä sekä arkikielen käsitteinä että tieteellisinä käsitteinä, ei oppikirjoissa käsitellä. Sama näkyy ylioppilaskoeaineistossa: oppilaat eivät hallitse käsitettä kertoja tieteellisenä käsitteenä. Tietoisuus kirjallisuustieteellisten käsitteiden määrittelyn problematiikasta ja arkikäsitteiden ja tieteellisten käsitteiden ontologisista kategorioista on onnistuneen käsitteenoppimisen edellytys. Kirjallisuustieteelliset käsitteet ovat metakäsitteitä, jotka edellyttävät oppilaiden metakäsitteellisen tietoisuuden ja motivaation hyödyntämistä opetuksessa, jossa olisi sovellettava monipuolisesti eri oppimiskäsitysten parhaita puolia hyödyntäviä lähestymistapoja, erilaisia pedagogisia diskursseja. Koulujen kirjallisuudenopetusta suunniteltaessa ja kirjallisuustieteellisiä käsitteitä opetettaessa on otettava huomioon niin kirjallisuustieteen kuin kasvatustieteen näkökulma. Opetussuunnitelman ja ylioppilaskokeen asettama vaatimus käsitteiden käytöstä on kohtuuton, mikäli ei sovita, miten käsitteet määritellään ja mitä käsitteitä kokelaiden oletetaan ylioppilaskokeessa hallitsevan. Kirjallisuustieteellisten käsitteiden puutteellisen opetuksen oppikirjoissa ja niiden epämääräisen käytön ylioppilaskokeen tehtävänannoissa ja arvioinnissa voi kärjistyneimmillään nähdä oppilaan oikeusturvakysymyksenä

From the world of fiction literature into multi-cultural Finland. Anticipatory story as an educational tool in teaching of literature and multiculturalism The research clarifies the relationship between reading fiction literature and multicultural value education in basic education. The research focuses on the subject didactics of mother tongue and literature and on the literature teaching in particular. The objective is to develop a method that is easily transferable into a teaching context so as to intensify the educational discussion based on fiction literature. In essence, understanding fiction literature and the ethical and moral thinking resemble one another, because both of them aim at empathizing with the thinking of a person or with a situation foreign to oneself. For this reason fiction literature is ideally suited for the discussion on ethical and moral values within a subject entity in the basic education. The empirical unit of the research consists of two parts. The first part explains how youth novels published in the years 1993 – 2007 describe multiculturalism in Finnish society. Books on multiculturalism are still few in number within youth literature, and people with a foreign background are mainly minor or background characters in such literary works. Nevertheless, youth novels serve well as a starting point for an educational discussion about multicultural issues. More often than not characters in youth novels are stereotypes and even opposite to each other. The juxtaposing makes a young reader question the stereotypes associated with immigrants. Besides the stereotype, reference to a prototype or a model is possible. The second part tests the usefulness of an anticipatory story based on a fictive text for an educational discussion about multicultural issues. The empirical material was collected from the eighth-grade teaching groups in basic education as follows: one teaching group was an immigrant group, the second one a group of Finns with experience of immigrants while the third group of students had hardly any experience of immigrants. The anticipatory stories were written on the basis of extracts from youth novels with multicultural themes. The material collected for a total of 120 anticipatory stories was analysed by using meaning cue analysis. Using the meaning cue analysis, the anticipatory stories were divided into three groups: stories with predominantly positive meaning cues of interculturalism, ambivalent stories with both positive and negative meaning cues of interculturalism and the stories with predominantly negative meaning cues of interculturalism. The meaning cues produced by girls and boys differ from one another, in particular, by the negative meaning cues of interculturalism. For girls, the predominant meaning cue is fear whereas for boys, it is that of violence. It would also seem that the students, in particular, boys with little experience of immigrants produce more negative meaning cues of interculturalism than do immigrants or Finnish students with experience of immigrants. Further still, it seems that active reading of fiction literature affects the meaning cues of interculturalism in an ambivalent direction. In the way of youth novels this is understandable, because youth novels in general are made up of opposite characters and meaning cues. The less the student takes an interest in reading, the more he used meaning cues from outside the parent text for his anticipatory story. No doubt it would be possible to use fiction literature in the literature education to a much higher extent than it is being used today whereby the literature could be used in basic education for reviewing subject entities or study contents of other study subjects. By way of an anticipatory story and the meaning cue analysis, it is possible to intensify the educational discussions based on fiction literature. However, using fiction literature in the literature education requires consideration of the specific genre of fiction literature.

Teaching the measurement of blood pressure for both nursing and public health nursing students The purpose of this two-phase study was to develop the teaching of blood pressure measurement within the nursing degree programmes of the Universities of Applied Sciences. The first survey phase described what and how blood pressure measurement was taught within nursing degree programmes. The second intervention phase (2004-2005) evaluated first academic year nursing and public health nursing students’ knowledge and skills results for blood pressure measurement. Additionally, the effect on the Taitoviikko experimental group students’ blood pressure measurement knowledge and skills level. A further objective was to construct models for an instrument (RRmittTest) to evaluate nursing students measurement of blood pressure (2003-2009). The research data for the survey phase were collected from teachers (total sampling, N=107, response rate 77%) using a specially developed RRmittopetus-questionnaire. Quasi-experimental study data on the RRmittTest-instrument was collected from students (purposive sampling, experimental group, n=29, control group, n=44). The RRmittTest consisted of a test of knowledge (Tietotesti) and simulation-based test (TaitoSimkäsi and Taitovideo) of skills. Measurements were made immediately after the teaching and in clinical practice. Statistical methods were used to analyse the results and responses to open-ended questions were organised and classified. Due to the small amount of materials involved and the results of distribution tests of the variables, non-parametric analytic methods were mainly used. Experimental group and control group similar knowledge and skills teaching was based on the results of the national survey phase (RRmittopetus) questionnaire results. Experimental group teaching includes the supervised Taitoviikko teaching method. During Taitoviikko students studied blood pressure measurement at the municipal hospital in a real nursing environment, guided by a teacher and a clinical nursing professional. In order to evaluate both learning and teaching the processes and components of blood pressure measurement were clearly defined as follows: the reliability of measurement instruments, activities preceding blood pressure measurement, technical execution of the measurement, recording, lifestyle guidance and measurement at home (self-monitoring). According to the survey study, blood pressure measurement is most often taught at Universities of Applied Sciences, separately, as knowledge (teaching of theory, 2 hours) and skills (classroom practice, 4 hours). The teaching was implemented largely in a classroom and was based mainly on a textbook. In the intervention phase the students had good knowledge of blood pressure measurement. However, their blood pressure measurement skills were deficient and the control group students, in particular, were highly deficient. Following in clinical practice the experimental group and control group students’ blood pressure measurement recording knowledge improve and experimental groups declined lifestyle guidance. Skills did not improve within any of the components analysed. The control groups` skills on the whole, declined statistically.There was a significant decline amongst the experimental group although only in one component measured. The results describe the learning results for first academic year students and no parallel conclusions should be drawn when considering any learning results for graduating students. The results support the use and further development of the Taitoviiko teaching method. The RRmittTest developed for the study should be assessed and the results seen from a negative perspective. This evaluation tool needs to be developed and retested.

The development of correct programs is a core problem in computer science. Although formal verification methods for establishing correctness with mathematical rigor are available, programmers often find these difficult to put into practice. One hurdle is deriving the loop invariants and proving that the code maintains them. So called correct-by-construction methods aim to alleviate this issue by integrating verification into the programming workflow. Invariant-based programming is a practical correct-by-construction method in which the programmer first establishes the invariant structure, and then incrementally extends the program in steps of adding code and proving after each addition that the code is consistent with the invariants. In this way, the program is kept internally consistent throughout its development, and the construction of the correctness arguments (proofs) becomes an integral part of the programming workflow. A characteristic of the approach is that programs are described as invariant diagrams, a graphical notation similar to the state charts familiar to programmers. Invariant-based programming is a new method that has not been evaluated in large scale studies yet. The most important prerequisite for feasibility on a larger scale is a high degree of automation. The goal of the Socos project has been to build tools to assist the construction and verification of programs using the method. This thesis describes the implementation and evaluation of a prototype tool in the context of the Socos project. The tool supports the drawing of the diagrams, automatic derivation and discharging of verification conditions, and interactive proofs. It is used to develop programs that are correct by construction. The tool consists of a diagrammatic environment connected to a verification condition generator and an existing state-of-the-art theorem prover. Its core is a semantics for translating diagrams into verification conditions, which are sent to the underlying theorem prover. We describe a concrete method for 1) deriving sufficient conditions for total correctness of an invariant diagram; 2) sending the conditions to the theorem prover for simplification; and 3) reporting the results of the simplification to the programmer in a way that is consistent with the invariantbased programming workflow and that allows errors in the program specification to be efficiently detected. The tool uses an efficient automatic proof strategy to prove as many conditions as possible automatically and lets the remaining conditions be proved interactively. The tool is based on the verification system PVS and i uses the SMT (Satisfiability Modulo Theories) solver Yices as a catch-all decision procedure. Conditions that were not discharged automatically may be proved interactively using the PVS proof assistant. The programming workflow is very similar to the process by which a mathematical theory is developed inside a computer supported theorem prover environment such as PVS. The programmer reduces a large verification problem with the aid of the tool into a set of smaller problems (lemmas), and he can substantially improve the degree of proof automation by developing specialized background theories and proof strategies to support the specification and verification of a specific class of programs. We demonstrate this workflow by describing in detail the construction of a verified sorting algorithm. Tool-supported verification often has little to no presence in computer science (CS) curricula. Furthermore, program verification is frequently introduced as an advanced and purely theoretical topic that is not connected to the workflow taught in the early and practically oriented programming courses. Our hypothesis is that verification could be introduced early in the CS education, and that verification tools could be used in the classroom to support the teaching of formal methods. A prototype of Socos has been used in a course at Åbo Akademi University targeted at first and second year undergraduate students. We evaluate the use of Socos in the course as part of a case study carried out in 2007.

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.

Engelskans dominerande roll som internationellt språk och andra globaliseringstrender påverkar också Svenskfinland. Dessa trender påverkar i sin tur förutsättningarna för lärande och undervisning i engelska som främmande språk, det vill säga undervisningsmålen, de förväntade elev- och lärarroller, materialens ändamålsenlighet, lärares och elevers initiala erfarenheter av engelska och engelskspråkiga länder. Denna studie undersöker förutsättningarna för lärande och professionell utveckling i det svenskspråkiga nybörjarklassrummet i engelska som främmande språk. Utgångsläget för 351 nybörjare i engelska som främmande språk och 19 av deras lärare beskrivs och analyseras. Resultaten tyder på att engelska håller på att bli ett andraspråk snarare än ett traditionellt främmande språk för många unga elever. Dessa elever har också goda förutsättningar att lära sig engelska utanför skolan. Sådan var dock inte situationen för alla elever, vilket tyder på att det finns en anmärkningsvärd heterogenitet och även regional variation i det finlandssvenska klassrummet i engelska som främmande språk. Lärarresultaten tyder på att vissa lärare har klarat av att på ett konstruktivt sätt att tackla de förutsättningar de möter. Andra lärare uttrycker frustration över sin arbetssituation, läroplanen, undervisningsmaterialen och andra aktörer som kommer är av betydelse för skolmiljön. Studien påvisar att förutsättningarna för lärande och undervisning i engelska som främmande språk varierar i Svenskfinland. För att stöda elevers och lärares utveckling föreslås att dialogen mellan aktörer på olika nivå i samhället bör förbättras och systematiseras.

Työn tavoitteena on luoda poikkileikkaus ongelmalähtöiseen pedagogiikkaan ja erityisesti sen käyttömahdollisuuksiin Yrityspeli-kurssin opettamisessa oppimislähtöisen opetustavan tukena. Toisena tavoitteena on kurssin pelisovelluksen dokumentointi käyttökelpoiseksi viiteteokseksi. Lopuksi työssä tutkitaan sovelluksen keskeisten parametrien ja pelistrategioiden vaikutusta kysyntään. Ongelmalähtöistä oppimista on tutkittu lähinnä kirjallisuuteen perustuen ja täydennetty tietämystä haastattelututkimuksella. Sovelluksen rakenne on havainnoitu käyttämällä sovellusta. Sovelluksen kriittisiä ominaisuuksia on saatu selville ajamalla sovellusta tarkoitusta varten valikoidulla numeerisella aineistolla. Ongelmalähtöinen pedagogiikka osoittautui soveltuvin osin hyväksi opetusmenetelmäksi Yrityspeli-kurssilla mallintamisen ja käytännön ongelmanratkaisutaitojen kehittämisessä. Kurssin pelisovellus näyttäisi toimivan luotettavasti, tosin se ei ole rakenteeltaan erityisen joustava. Sovelluksen keskeisistä parametreista hinnan vaikutus kysyntään on huomattavasti markkinointipanosta suurempi. Testien mukaan pelissä on mahdollista pärjätä niin kustannusjohtajan kuin hintadifferoijankin strategialla.

Tämän tutkimuksen tavoitteena on selvittää opintojensa alussa olevien yliopisto-opiskelijoiden vaikeimpina pitämät käytännön ohjelmoinnin aihealueet sekä koostaa luentomoniste käytettäväksi seuraavalla alkavalla Käytännön ohjelmointi -kurssilla. Tutkimusmetodina käytettiin konstruktiivista tutkimusmetodia, jossa tavoitteen spesifioinnin jälkeen implementoitiin luentomoniste koostamalla määriteltyjen aihekokonaisuuksien lähdemateriaalia yhtenäiseksi, luettavaksi kokonaisuudeksi. Yliopistoissa ei yleisesti opeteta ohjelmistojen testausta ennen syventäviä ohjelmistotekniikan kursseja, mikä on kuitenkin puute työelämän kannalta. Tässä työssä esitetään perusteluja käytännönläheisten aihekokonaisuuksien painottamiselle ohjelmointikursseilla jo yliopisto-opintojen alkuvaiheessa. Työssä käsitellään Käytännön ohjelmointi -kurssin kurssipalautetta, missä havaittiin opiskelijoiden pitävän kurssin hankalimpina aihealueina linkitettyä listaa, osoittimia, dynaamista muistinhallintaa, tietorakenteita ja versionhallintaa. Työn avulla on pyritty kehittämään käytännön ohjelmoinnin yliopisto-opetusta Lappeenrannan teknillisessä yliopistossa luentomateriaalin avulla, jossa on muun muassa teoriaa, keskeisiä opiskelijoiden tarvitsemia komentoja, www-linkkejä sekä ohjelmoinnin tyyliopas.
