Keitä me olemme? : kartoitus ensimmäisen vuoden luokanopettajaopiskelijoiden koulutus- ja perhetaustasta, uskonnollisesta vakaumuksesta, poliittisest…
2015
Tämä tutkimus on kartoitus Jyväskylän luokanopettajaopiskelijoiden ensimmäisen vuosikurssin opiskelija-aineksesta. Olemme selvittäneet tämän opiskelijaryhmän perustietoja sekä ominaisuuksia. Iän, sukupuolen ja siviilisäädyn lisäksi sisällytimme perustietoihin perhetaustan sekä koulutustaustan. Näiden perustietojen lisäksi tutkimme ryhmän uskonnollista vakaumusta sekä poliittista kantaa, harrastuneisuutta sekä vapaa-ajan viettoa sisältäen henkisen hyvinvoinnin näkökulman. Lopuksi selvitimme myös luokanopettajaopiskelijoiden päihteiden käyttöä, erilaisiin rikkeisiin syyllistymistä sekä seksuaalikäyttäytymistä. Luokanopettajat ovat tärkeä osa yhteiskunnan rakennetta. He toimivat tulevien täysi…
Assessment of fish migration in rivers by horizontal echo sounding : problems concerning side-aspect target strength
2004
Liljan tutkimus osoittaa, että sivuttaissuuntaisella kaikuluotauksella pystytään hyvin havaitsemaan vastavirtaan uivat kalat. Kalan koon määrittäminen sekä lajien erottaminen toisistaan monilajisessa kalayhteisössä ei ole kuitenkaan mahdollista tarkastelemalla pelkästään heijastunutta kaikua. Liljan mukaan kaikuluotaustutkimuksiin onkin syytä yhdistää koekalastukset aina, kun läsnä on tutkittavan lajin lisäksi muita kalalajeja.Kiinteästi paikalleen asetettuja lohkokeilakaikuluotaimia on käytetty jokeen nousevien emolohien lukumäärän arvioinnissa 1990-luvun vaihteesta lähtien. Menetelmässä kalat läpäisevät kaikuluotaimen lähettämän äänikeilan aktiivisesti uimalla ja tulevat näin rekisteröidy…
The structural validity of the Finnish version of the Disabilities of the Arm, Shoulder and Hand : a Rasch model analysis
2020
Abstract Introduction: The construct validity of the Disabilities of the Arm, Shoulder and Hand questionnaire (DASH) has previously been questioned. The purpose of this study was to evaluate the measurement properties of the Finnish version of the DASH for assessing disability in patients with hand complaints using Rasch Measurement Theory. Methods: A cohort of 193 patients with typical hand and wrist complaints were recruited at a surgery outpatient clinic. The DASH scores were analysed using the Rasch model for differential item functioning, unidimensionality, fit statistics, item residual correlation, coverage/targeting and reliability. Results: In the original DASH questionnaire, the it…
An Updated Guideline for Assessing Discriminant Validity
2022
Discriminant validity was originally presented as a set of empirical criteria that can be assessed from multitrait-multimethod (MTMM) matrices. Because datasets used by applied researchers rarely lend themselves to MTMM analysis, the need to assess discriminant validity in empirical research has led to the introduction of numerous techniques, some of which have been introduced in an ad hoc manner and without rigorous methodological support. We review various definitions of and techniques for assessing discriminant validity and provide a generalized definition of discriminant validity based on the correlation between two measures after measurement error has been considered. We then review te…
The meaningfulness of two curriculum-based national tests of English as a foreign language
2022
This paper addresses the aspect of the meaningfulness of a national assessment in English as a foreign language, applying the fairness framework proposed by Kunnan (2018). We compared students’ performance on two receptive language skills of listening and reading on two subsequent national evaluations in Finland, taken by students at the end of compulsory basic education and at the end of general upper secondary education, respectively. The research questions focus on (1) the relationship between students’ performance on the two tests and their gender, language of schooling and parents’ educational level, and (2) the relationship between the students’ receptive language proficiency at the e…
Methodological Guidelines Designed to Improve the Quality of Research on Cross-Country Skiing
2021
AbstractCross-country (XC) ski races involve a variety of formats, two different techniques and tracks with highly variable topography and environmental conditions. In addition, XC skiing is a major component of both Nordic combined and biathlon competitions. Research in this area, both in the laboratory and field, encounters certain difficulties that may reduce the reliability and validity of the data obtained, as well as complicate comparisons between studies. Here, 13 international experts propose specific guidelines designed to enhance the quality of research and publications on XC skiing, as well as on the biathlon and Nordic combined skiing. We consider biomechanical (kinematic, kinet…
A systematic review of functional numeracy measures for 9–12 -year-olds: Validity and reliability evidence
2023
This systematic review aimed to summarize the characteristics and the measurement properties of functional numeracy measures developed for use by teachers among 9–12-year-old children with or without mathematical learning difficulties. A systematic search from five databases was conducted based on pre-defined criteria. PRISMA guidelines were followed for reporting the results. The terminology and classification of measurement properties adopted by the COSMIN taxonomy was used. Twenty-one studies of 18 measures met the inclusion criteria. Most of the identified measures did not report on several measurement properties due to incomplete or missing psychometric data. Knowledge of Mathematical …

Measures of the Massive Mountain in Aleksis Kivi’s Play Kullervo
2022
The story of a prisoner inside an enormous steel mountain is embedded in Kullervo, an early Finnish tragedy by 19th-century author Aleksis Kivi. I focus here on the exceptional size of the mountain, as told by the main character, Kullervo. Although the embedded story has aroused admiration in research, the mountain’s size and form do not appear to have done so. If taken literally, and assuming the shape of a double pyramid, at a minimum, the mountain’s surface area would be between that of Earth and Uranus, a planet that Kivi was somehow aware of. The mountain’s maximum surface area and volume would greatly exceed that of the Sun. This mountain cannot be localized in the near environment of…
