Trends in International Mathematics and Science Study

"Eighth grade" in the United States is approximately 13–14 years of age and equivalent to: "Fourth grade" in the United States is approximately equivalent to 9–10 years of age and equivalent to: A precursor to TIMSS was the First International Mathematics Study (FIMS) performed in 1964 in 11 countries for students aged 13 and in the final year of secondary education (FS) under the auspices of the International Association for the Evaluation of Educational Achievement (IEA).

The sixth cycle was conducted in 2015, and the results were released in 2016;[5] the data set was published in February 2017.

Policy-relevant data about curriculum emphasis, technology use, and teacher preparation and training accompanies the TIMSS Advanced results.

In addition, TIMSS provides contextual data on crucial curricular, instructional, and resource-related factors that can impact the teaching and learning process.

"[8] Because TIMSS is administered in four-year cycles, it enables participating counties to use the results between the fourth and eighth grades to track the changes in achievement and certain background factors from an earlier study.

[14] This application allows researchers to combine data files and facilitates some types of statistical analysis (such as computing means, percentages, percentiles, correlations, and estimating single level multiple linear regression).

The application takes into account the complex sample structure of the databases when calculating the statistics and their standard errors.

[15] TIMSS 2019 was the seventh cycle of TIMSS and reported overall achievement as well as results according to international benchmarks, by major content domains (number, algebra, and geometry in mathematics, and earth science, biology, and chemistry in science) and by cognitive domains (knowing, applying, reasoning).

[17] TIMSS 2019 marked the transition to a digital assessment format, allowing for new and innovative item types.

The digital version of TIMSS 2019 also introduced Problem Solving and Inquiry tasks that simulated real-world and laboratory situations and called for students to integrate and apply process skills and content knowledge.

[7] This detailed report presents achievement and contextual data from participating countries and benchmarking entities.

[37] In TIMSS 1995,[40] there were 41 educational systems in five grades (third, fourth, seventh, eighth, and the final year of secondary school).

TIMSS depends on the collaboration of a large number of individuals and organizations around the world including the TIMSS & PIRLS International Study Center at Boston College, IEA's offices in Amsterdam and Hamburg, Statistics Canada, and Educational Testing Service (ETS).

[6] Hanushek and Woessmann[54] developed a methodology to rescale 14 different international comparisons of math and/or science achievement to make them comparable.

TIMSS questions focus on the mathematics curricula taught around the world as seen in TIMSS example items,[58] while PISA attempts to assess mathematics embedded in descriptions of situations encountered outside of the classroom, see PISA examples.
