Ability of Olympiad Winning Student in Doing STEAM-based Test: Analysis of Literacy and Numeracy

Literacy and numeracy abilities and critical thinking are very important challenges in the 21st century. It is important to develop stats from the level of elementary education. The results of literacy and numeracy shows that there is a significant problem. Based on the International Student Assessment Program (PISA) 2019 held by OECD, which evaluates the students’ ability in various countries, about 1% of Indonesian students can solve the complex question model mathematically, even in the result of (PISA) released in 2023 about the ability of literacy and numeracy. Indonesia ranked 68 out of 81 countries and if compared with the result in 2018, it was significantly lower. This research aims to describe the ability of literacy and numeracy and also critical thinking of the Olympiad-winning student in solving the questions using STEAM-based test. The research uses qualitative approach, with the method of case study taken from the Junior High School student who wins the mathematics Olympiad. The research instrument was a test that consisted of 5 STEAM based questions. The data collection technique was giving test and it is continued with the interview based on the test result. The result of the research shows that the ability of literacy and numeracy in solving the test refers to the field of science, art, and mathematical subject to communicate, makes the students to be able to change the essay question to the mathematics form. The students can think logically, make valid statements, and construct strategy in solving the test using formal language and symbolic operation. While the test related with the technology, has an error in specifying the steps. In general, the subject’s numeracy literacy skills are good.
