The average mathematics proficiency of Indonesian students declined in 2022.
This is evident from the 2022 Programme for International Student Assessment (PISA) report released by the Organization for Economic Co-operation and Development (OECD).
PISA defines mathematical proficiency as "the capacity to formulate, employ, and interpret mathematics in a variety of contexts to describe, predict, and explain phenomena."
To measure this proficiency, PISA conducts tests and surveys on a sample of 15-year-old students from dozens of countries.
PISA then classifies mathematical proficiency into 8 levels, from the highest level 6, 5, 4, 3, 2, 1a, 1b, to 1c. The higher the number, the better the assumed proficiency.
In 2022, Indonesian students achieved a mathematics proficiency score of 366 points, down from the PISA assessment results from 2015-2018.
This score is also significantly below the average score of OECD member countries, which ranges from 465-475 points.
With a score of 366, in 2022 the mathematical proficiency of Indonesian students fell into level 1a.
This means that, in general, Indonesian students can answer mathematical questions involving simple contexts, with clearly defined question conditions, and all necessary information provided.
Students with level 1a mathematical proficiency can also use basic algorithms, formulas, or procedures to solve problems that generally involve integers.
However, students at this level are not yet able to think creatively to formulate solutions to more complex problems.
