Analysing Sweden in PISA (ASIP)

The project examines the representativeness and validity of PISA 2018 in Sweden. For this purpose, ASIP considers on the one hand whether the PISA sample is representative or biased and analyzes on the other hand differences between the PISA tests, national tests and school grades.

Project description

The overall aim of ASIP is to determine the trustworthiness of the test scores of the Programme for International Student Assessment (PISA) 2018 in Sweden. To reach that aim, we will investigate whether the PISA sample is biased and determine if students’ test-scores translate into their national test results and grades.

ASIP combines data from PISA with the national assessments as well as register data including grades and applies a novel and strong design which has not been carried out previously. PISA has extensive impact on public discussions and research as well as on policy-makers–but are the results trustworthy? ASIP aims to answer this question.

We combine PISA 2018 data with register data from Sweden. We will conduct a non-response-bias-analyses, bi-factor CFA modeling, and mediation analyses to study the representativeness of PISA in Sweden and measurement properties of the PISA test.

Location & approach

The most convenient highway exits are on the B 1/A 40 (Dortmund-Barop) (closer to the North Campus) and on the A45 (Dortmund-Eichlinghofen). The university is signposted at both exits. In the local road network you will find signs to Campus Nord, where the Campus Treff is also located. From Emil-Figge-Strasse, entrance no. 18 and from Vogelspothsweg entrance no. 23 lead to parking spaces near the venue.

From Dortmund main station, take the S-Bahn "S1" in the direction of Solingen on track 7 to the stop "Dortmund-Universität" (price level A). The S-Bahn runs every 15 minutes during peak hours on weekdays and takes about 6 minutes. From Düsseldorf, the S-Bahn runs every 30 minutes. Directly at the S-Bahn station you will find the CDI building, which houses the Center for Research on Education and School Development.

One of the university's landmarks is the H-Bahn, which has two terminuses on the North Campus. One is located directly above the S-Bahn station and is easily accessible from it by elevators. The other is located in the center of Campus North at the bridge between the University Library and the Mensa, right next to the Audimax. The H-Bahn runs from here to the South Campus and the Eichlinghofen district.

Dortmund has an airport connected with some destinations in Central Europe. There are regular flights, for example, to Amsterdam, Berlin, Dresden, Katowice, Krakow, Leipzig-Halle, London, Munich, Nuremberg, Paris, Poznan, Stuttgart, Vienna and Zurich. For the approximately 20 kilometers from the Dortmund airport to the campus, you can take the bus to the main train station and from there the S-Bahn. Faster is usually the use of a cab. Far more international flight connections are offered by the Rhine-Ruhr Airport in Düsseldorf, about 60 kilometers away, which can be reached directly by S-Bahn from the university station.
