Teaching and Learning International Survey – Video Study (TALIS-Video)

The TALIS Video Study is an international study on school instruction which assesses the effectiveness of mathematics education in different countries.

Project Description

The OECD study TALIS-Video aims at gaining insights into the characteristics of good and successful mathematics education in different countries, and investigates how instructional processes are linked to students’ learning achievements and their motivational characteristics.

The same instructional unit on quadratic equations is assessed in all participating classrooms to enable a comparison within and across countries. Owing to its longitudinal design, the TALIS video study covers learning prerequisites, teaching and learning processes as well as learning outcomes of the exemplarily chosen lesson unit which spans several weeks.

TALIS-Video combines multiple perspectives on mathematics education:

  1. Students are initially asked to fill out a questionnaire querying their lessons as well as their attitudes, motivation and interests. In order to link instructional processes with their learning achievement, another questionnaire is submitted to the students after they have experienced the teaching unit.
  2. Prior to the teaching unit, the students participate in a mathematics test which assesses relevant knowledge. Following the teaching unit, the students’ knowledge about quadratic equations is determined in a further test.
  3. In addition, the teachers are asked to fill out questionnaires before and after teaching the unit on quadratic equations, e.g. regarding their perspective on mathematics education.
  4. In the course of the lesson unit, two lessons are filmed.
  5. The teaching materials used during lessons are collected.

Participating Countries and Random Sample Size

Altogether, nine countries are participating in the study, e.g. the USA, Japan and Germany. These countries already participated in the first large-scale TIMSS video study. Moreover, Shanghai, an internationally recognised education system, is participating. England is another participant, as are four Spanish-speaking education systems (Chile, Columbia, Mexico and the region of Madrid). In all nine countries, 85 mathematics classes from lower secondary schools are assessed.


An international consortium is in charge of co-ordinating the study. DIPF is a member of this consortium, as are the US-American organisations ETS and RAND. At DIPF, Professor Dr. Eckhard Klieme chairs the international, theoretical conceptualisation of instructional quality which represents the study’s matrix, the selection of the standardised lesson unit and questionnaire development.
