Unwanted Literal Translation: An Underdiscussed Problem in International Achievement Studies
2012
In international achievement studies, a common test is typically used which is translated into the languages of the participating countries. For the test to be valid, all the translations and different-language test versions need to be equally difficult to read and answer. An underestimated and underdiscussed threat to this validity is unwanted literal translation. This paper discusses the problem of unwanted literal translation in international achievement studies. It defines what is meant by unwanted literal translation and explains why it is a threat to the validity of international achievement studies and why it is so difficult to avoid. It also discusses problems there have been when t…
Problems and Issues in Translating International Educational Achievement Tests
2013
The article reviews research and findings on problems and issues faced when translating international academic achievement tests. The purpose is to draw attention to the problems, to help to develop the procedures followed when translating the tests, and to provide suggestions for further research. The problems concentrate on the following: the unique and demanding purpose of the translation task, the partly contradictory task specifications and translation instructions, the indecision as to whether to produce one or two target versions, the indecision as to whether to use one or two source versions, inadequate revision and verification, deficient translator competences, and a lack of time.…
International Education Studies: Increasing Their Linguistic Comparability by Developing Judgmental Reviews
2012
In international education studies, the different-language test versions need to be equally difficult to read and answer for the test to be valid. To ensure comparability, several quality control procedures have been developed. Among these, surprisingly little attention has been paid to judgmental reviews and their ability to identify language-related sources of bias. Also, the reviews have often failed in identifying biases. This paper explored whether it is possible to improve the ability of judgmental reviews to identify language-related sources of bias. A new review was made of two Finnish items which in the PISA (Programme for International Student Assessment) 2000 reading test showed …
Text authenticity in international reading literacy assessment : focusing on PISA 2000
2007
Sari Sulkunen tutki väitöstyössään PISAn (Programme for International Student Assessment) lukutaitokokeessa olleiden tekstien autenttisuutta eli tyypillisyyttä ja kiinnostavuutta suomalaisnuorten kokemuspiirissä. Hän selvitti PISAn lukukokeen tekstien kulttuurista sopivuutta 15-vuotiaille suomalaisnuorille. - PISAn lukutaitokokeessa vuonna 2000 olleet tekstit heijastavat aika huonosti suomalaisnuorten tekstimaailmaa. Tekstien tyypillisyys ja erityisesti kiinnostavuus osoittautui vaatimattomaksi, mutta tytöt arvioivat tekstit sekä tyypillisyyden että erityisesti kiinnostavuuden näkökulmasta poikia positiivisemmin. Erityisenä haasteena lukutaitokokeissa näyttää siis olevan poikia kiinnostavie…
The problem of equivalence in translating texts in international reading literacy studies : a text analytic study of three English and Finnish texts …
2007
Tutkimuksessa tarkasteltiin ongelmia, joita kansainvälisissä lukukokeissa on käännettäessä lukukoetekstejä osallistujamaiden kielille ja pyrittäessä samalla pitämään tekstien vaikeustaso muuttumattomana – sillä elleivät koetekstit ole vaikeustasoltaan ekvivalentteja, vertailukelpoisia, ei lukukoekaan ole validi. Tieto ongelmista on tarpeen, koska se auttaa tekemään käännöksistä laadukkaampia ja vertailukelpoisempia, mikä vuorostaan johtaa luotettavampiin, pätevämpiin ja tasa-arvoisempiin lukukokeisiin. Tutkimuksen aineistona käytettiin kolmea PISA 2000 -lukukokeeseen sisältynyttä englanninkielistä lähtötekstiä ja niiden suomennosta. Tekstit edustivat eri tekstityyppejä: yksi oli ekspositori…
Reliability and validity of a new accelerometer-based device for detecting physical activities and energy expenditure.
2018
Background Objective assessments of sedentary behavior and physical activity (PA) by using accelerometer-based wearable devices are ever expanding, given their importance in the global context of health maintenance. This study aimed to determine the reliability and validity of a new accelerometer-based analyzer (Fibion) for detecting different PAs and estimating energy expenditure (EE) during a simulated free-living day. Methods The study consisted of two parts: a reliability (n = 18) and a validity (n = 19) test. Reliability was assessed by a 45 min protocol of repeated sitting, standing, and walking (i.e., 3 × 15 min, repeated twice), using both Fibion and ActiGraph. Validity was assesse…

Reliability and validity of time domain heart rate variability during daily rout¡ne activities : an alternative to the morning orthostatic test?
2017
Summary Study aim: To determine the reliability and validity of a time domain heart rate variability (HRV) index during free-living physical activity (FLPA). Material and methods: Eight white-collar workers participated in this study. RR intervals (time between consecutive R-peaks of the PQRS complex) were recorded using the Polar V800 heart rate (HR) monitor upon awakening and at work on 16 different days. A total of 127 cycles of sitting periods followed by walking breaks were included for consecutive pairwise analysis for reliability. The HR values from the orthostatic test (OT) were compared with the corresponding values at work. Results: The HR values showed high levels of repeatabilit…
