Kysynnän ennustaminen leipomotuotteille ja ennusteen tarkkuuden arviointi

Tässä diplomityössä tutkittiin kysynnän ennustamista Vaasan & Vaasan Oy:n tuotteille. Ensin työssä perehdyttiin ennustamiseen ja sen tarjoamiin mahdollisuuksiin yrityksessä. Erityisesti kysynnän ennustamisesta saatavat hyödyt käytiin läpi. Kysynnän ennustamisesta haettiin ratkaisua erityisesti ongelmiin työvuorosuunnittelussa.Työssä perehdyttiin ennustemenetelmiin liittyvään kirjallisuuteen, jonka oppien perusteella tehtiin koe-ennustuksia yrityksen kysynnän historiadatan avulla. Koe-ennustuksia tehtiin kuudelle eri Turun leipomon koe-tuotteelle. Ennustettavana aikavälinä oli kahden viikon päiväkohtainen kysyntä. Tämän aikavälin erityisesti peruskysynnälle etsittiin ennustetarkkuudeltaan parasta kvantitatiivista ennustemenetelmää. Koe-ennustuksia tehtiin liukuvilla keskiarvoilla, klassisella aikasarja-analyysillä, eksponentiaalisen tasoituksen menetelmällä, Holtin lineaarisella eksponenttitasoituksen menetelmällä, Wintersin kausittaisella eksponentiaalisella tasoituksella, autoregressiivisillä malleilla, Box-Jenkinsin menetelmällä ja regressioanalyysillä. Myös neuroverkon opettamista historiadatalla ja käyttämistä ongelman ratkaisun apuna kokeiltiin.Koe-ennustuksien tulosten perusteella ennustemenetelmien toimintaa analysoitiin jatkokehitystä varten. Ennustetarkkuuden lisäksi arvioitiin mallin yksinkertaisuutta, helppokäyttöisyyttä ja sopivuutta yrityksen monien tuotteiden ennustamiseen. Myös kausivaihteluihin, trendeihin ja erikoispäiviin kiinnitettiin huomiota. Ennustetarkkuuden huomattiin parantuvan selvästi peruskysyntää ennustettaessa, jos ensin historiadata esikäsittelemällä puhdistettiin erikoispäivistä ja –viikoista.

Prosessilähtöinen laadunarviointi ohutlevymekaniikkasopimusvalmistajan näkökulmasta

Diplomityö on tehty Lappeenrannan teknillisessä korkeakoulussa Konepajatekniikan laitoksella. Työ on osa Konepajatekniikan laitoksen toteuttamaa ”LELA” levytuotteiden laadunvalvontaprojektia. Projektiosapuolet olivat: Abloy Oy (Joensuu), Flextronics Enclosures (Oulu), Hihra Oy (Turku), Lillbacka Oy (Alahärmä), Nokia Networks (Oulu), Segerström & Svensson (Uusikaupunki) ja Scanfil Oy (Sievi). Lisäksi projektin pääasiallisena rahoittavana osapuolena toimi Teknologian kehittämiskeskus, Tekes. Työ perustui ohutlevykomponentteja valmistavissa kohdeyrityksissä suoritettuun laadunarviointitutkimukseen, joka sisälsi tuotantoon kohdistetun virhekartoituksen sekä laadunarviointikyselyn. Tutkimuksessa suoritetun tuotannon virhekartoituksen mukaan tyypillisessä ohutlevykomponentteja valmistavassa yrityksessä virheidenesiintymistodennäköisyys on n. 5 – 12 % / tuote. Eniten virheitä syntyi epäkeskopuristintöissä. Tutkimus osoittaa, että virhekartoituksen avulla yrityksen on mahdollista kartoittaa tuotannossa syntyvät virheet ja edelleen kohdistaa laadun kehitystoimenpiteet oikeisiin tuotannon osa-alueisiin.

Opettajan monikulttuurinen työ

Teacher's multicultural work The purpose of the present study is to explore teachers’ conceptions of their work as teachers of multicultural students. Teachers’ experiences of multicultural work and conceptions derived from them are part of the teacher’s multicultural competence which is seen as a key component of the teacher’s multicultural teachership. The teacher’s multicultural competence consists of the teacher’s cultural knowledge, pedagogical skills and experiences and attitudes related to multiculturalism. The teacher’s multicultural competence constitutes the basis on which the teacher implements multicultural education. The foundation for the teacher’s work is laid by laws and decrees, curricula, regulations issued by authorities in charge of the education of immigrant students, resources available and other demands and expectations set by the ambient society. The study was conducted in the city of Turku, Finland. The sample consisted of class teachers who taught both immigrant and majority students. Main objects of study in the theoretical part are the multicultural and pluralistic school and the multicultural teachership. The basic assumption is that the multicultural and pluralistic school forms the frame of activity in which the teacher implements multicultural teaching. The research strategy is based on methodological triangulation. The quantitative part of the study was carried out using a questionnaire typical of survey methods. The questionnaire was returned by 71 teachers. The qualitative part was conducted using theme-based interviews typical of phenomenological philosophical research. Of the total of teachers who returned the questionnaire, twelve (12) teachers were selected for interviews. According to the results, the participating teachers enjoyed their work regardless of the ample extra work caused by the students with immigrant backgrounds. The teachers experienced their work as teachers of multicultural student groups as strenuous, yet challenging. Students with immigrant backgrounds had caused many changes in the teacher’s work. The teachers regarded their multicultural skills as inadequate in relation to the demands of the work. They had not received education related to teaching students with immigrant backgrounds, but they were ready for in-service education. The teachers’ previous attitudes concerning immigrant students had been enforced. Teaching experiences strengthened the earlier, both positive and negative, attitudes. The central problems related to multiculturalism in the teacher’s work were caused by the deficient Finnish skills of the students with immigrant background. This was apparent in both teaching and learning as well as in contacts with parents. The teachers reported on relatively few inclusions of multicultural angles in their teaching. However, they believed that they could aid students with different cultural backgrounds in their integration process. At the same time they felt that their own chances to enhance the students’ cultural identities were slim. On the basis of the interviews conducted in connection with the teacher’s multicultural competence, the teachers were divided into three groups: assimilative, indeterminate and integrating multicultural teachers. The present study provides a strong indication that teachers tend to interpret multiculturalism in narrow terms. School activities, such as Finnish as a second language, first language and religious instruction, which were targeted exclusively at immigrant students were in most cases considered adequate. A holistic, cross-disciplinary, all-inclusive multicultural education that would permeate all school activities remains largely unimplemented.

WorldSkills - ammattitaitovalmennus osana kone- ja metallialan kilpailukykyä

Nykyaikain ammattitaitovalmennus alkaa olla verrattavissa huippu-urheiluun ja sen sisältämiin valmennusprosesseihin. Tämän tutkimuksen tavoitteena oli kartoittaa ne prosessit, joita käyttämällä ammattitaitovalmennettava saadaan tiedollisesti ja taidollisesti mandollisimman hyvin valmennettua WorldSkills-tason kilpailuihin. Valittuja prosesseja soveltaen ohjeistetaan CAD-suunnittelun valmennus ja kokonaisvaltainen valmistautuminen kilpailuihin. Hyvänä taustapohjana on tutkimuksen tekijän omakohtainen osallistuminen Taitaja-2007 kilpailun järjestämiseen lajivastaavana CAD-suunnittelussa. Tutkimuksessa tehtiin myös kartoitus kilpailutoiminnan vaikuttavuudesta ja sen mandollisista vaikutuksista kone- ja metallialan koulutukseen hakeutuvien nuorten määriin. Tutkimuksen pääkohteina olivat Taitaja-kilpailujen järjestäjinä toimineet paikkakunnat ja koulutuksenjärjestäjät peräkkäisiltä vuosilta eli Turku, Tampere ja Joensuu. Tämän lisäksi Helsingissä järjestetty WorldSkills-2005 kilpailu aiheutti positiivisia vaikutuksia koko ammattitaitovalmennuksen kenttään ja sen esille nostamiseen ammatillisessa koulutuksessa. Näitä tietoja ja prosesseja voidaan käyttää hyväksi ammattitaitovalmennuksen kanssa toimivien oppilaitoksien, työpaikkojen ja valmentajien sekä muiden asiasta kiinnostuneiden tahojen jatkossa tehtävään valmennukseen liittyvään kehitystyöhön.

Evaluation of Teacher Education Programs by Students and Graduates

The purpose of this research was to do a repeated cross-sectional research on class teachers who study in the 4th year and also graduated at the Faculty of Education, University of Turku between the years of 2000 through 2004. Specifically, seven research questions were addressed to target the main purpose of the study: How do class teacher education masters’ degree senior students and graduates rate “importance; effectiveness; and quality” of training they have received at the Faculty of Education? Are there significant differences between overall ratings of importance; effectiveness and quality of training by year of graduation, sex, and age (for graduates) and sex and age (for senior students)? Is there significant relationship between respondents’ overall ratings of importance; effectiveness and their overall ratings of the quality of training and preparation they have received? Are there significant differences between graduates and senior students about importance, effectiveness, and quality of teacher education programs? And what do teachers’ [Graduates] believe about how increasing work experience has changed their opinions of their preservice training? Moreover the following concepts related to the instructional activities were studied: critical thinking skills, communication skills, attention to ethics, curriculum and instruction (planning), role of teacher and teaching knowledge, assessment skills, attention to continuous professional development, subject matters knowledge, knowledge of learning environment, and using educational technology. Researcher also tried to find influence of some moderator variables e.g. year of graduation, sex, and age on the dependent and independent variables. This study consisted of two questionnaires (a structured likert-scale and an open ended questionnaire). The population in study 1 was all senior students and 2000-2004 class teacher education masters’ degree from the departments of Teacher Education Faculty of Education at University of Turku. Of the 1020 students and graduates the researcher was able to find current addresses of 675 of the subjects and of the 675 graduates contacted, 439 or 66.2 percent responded to the survey. The population in study 2 was all class teachers who graduated from Turku University and now work in the few basic schools (59 Schools) in South- West Finland. 257 teachers answered to the open ended web-based questions. SPSS was used to produce standard deviations; Analysis of Variance; Pearson Product Moment Correlation (r); T-test; ANOVA, Bonferroni post-hoc test; and Polynomial Contrast tests meant to analyze linear trend. An alpha level of .05 was used to determine statistical significance. The results of the study showed that: A majority of the respondents (graduates and students) rated the overall importance, effectiveness and quality of the teacher education programs as important, effective and good. Generally speaking there were only a few significant differences between the cohorts and groups related to the background variables (gender, age). The different cohorts were rating the quality of the programs very similarly but some differences between the cohorts were found in the importance and effectiveness ratings. Graduates of 2001 and 2002 rated the importance of the program significantly higher than 2000 graduates. The effectiveness of the programs was rated significantly higher by 2001 and 2003 graduates than other groups. In spite of these individual differences between cohorts there were no linear trends among the year cohorts in any measure. In respondents’ ratings of the effectiveness of teacher education programs there was significant difference between males and females; females rated it higher than males. There were no significant differences between males’ and females’ ratings of the importance and quality of programs. In the ratings there was only one difference between age groups. Older graduates (35 years or older) rated the importance of the teacher training significantly higher that 25-35 years old graduates. In graduates’ ratings there were positive but relatively low correlations between all variables related to importance, effectiveness and quality of Teacher Education Programs. Generally speaking students’ ratings about importance, effectiveness and quality of teacher education program were very positive. There was only one significant difference related to the background variables. Females rated higher the effectiveness of the program. The comparison of students’ and graduates’ perception about importance, effectiveness, and quality of teacher education programs showed that there were no significant differences between graduates and students in the overall ratings. However there were differences in some individual variables. Students rated higher in importance of “Continuous Professional Development”, effectiveness of “Critical Thinking Skills” and “Using Educational Technology” and quality of “Advice received from the advisor”. Graduates rated higher in importance of “Knowledge of Learning Environment” and effectiveness of “Continuous Professional Development”. According to the qualitative data of study 2 some graduates expressed that their perceptions have not changed about the importance, effectiveness, and quality of training that they received during their study time. They pointed out that teacher education programs have provided them the basic theoretical/formal knowledge and some training of practical routines. However, a majority of the teachers seems to have somewhat critical opinions about the teacher education. These teachers were not satisfied with teacher education programs because they argued that the programs failed to meet their practical demands in different everyday situations of the classroom e.g. in coping with students’ learning difficulties, multiprofessional communication with parents and other professional groups (psychologists and social workers), and classroom management problems. Participants also emphasized more practice oriented knowledge of subject matter, evaluation methods and teachers’ rights and responsibilities. Therefore, they (54.1% of participants) suggested that teacher education departments should provide more practice-based courses and programs as well as closer collaboration between regular schools and teacher education departments in order to fill gap between theory and practice.
