LeseDif - Reading literacy against the background of social and cultural diversity: Differential meanings of item, student and instructional aspects in large scale assessments

Focusing reading literacy LeseDif analyses to what extent strengths and weaknesses of children who are socially disadvantaged and those with migration backgrounds are being influenced by (a) motivational characteristics of the learners and (b) quantitative and qualitative characteristics of instruction.

The research project LeseDif investigated reading competencies of primary school children in the context of social heterogeneity. The significance of task, pupil and classroom characteristics for the reading performance of fourth grade pupils was analysed using data from the German sample from IGLU 2006.

The effects on the reading performance of children from families with a low socio-economic status and children with a linguistic migration background were considered in particular, since despite common educational goals for all pupils, large differences in performance between the pupil subgroups were regularly reported in the large-scale assessments, among others.

Research and our own preliminary work on differential strengths and weaknesses had shown that especially children from educationally disadvantaged families showed relative deficits in open reading tasks in tests on reading.


However, this pattern could not be replicated for the most part using the IGLU 2016 data set to be processed - with the exception of a specific advantage for children with a more favourable socio-economic background in open compared to closed tasks in literary texts. The further work focused on the theoretically derived motivational conditioning factors and the relevance of quantitative and qualitative characteristics of instruction for the reading competence of pupils at the end of primary school.

On the one hand, the findings provide further scientific insights into explaining frequently reported systematic differences between the reading performance of different groups of pupils and contribute to further concretising theories on pupil- and classroom-related conditional factors of reading on the basis of the findings. On the other hand, the findings on motivational characteristics at the level of the students as well as on quantitative and qualitative aspects of their reading-related instruction with a view to educational practice also provide a basis for the discussion of possible starting points for school-based support in reading-related instruction and targeted interventions.

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.
