TY - JOUR A1 - Nidya, Ferry Wulandari A1 - Jailani, . PB - Faculty of Mathematics and Sciences Yogyakarta State University Y1 - 2015/// N2 - This study aims to describe the critical opinion of Indonesian students? problem solving skill based on PISA and TIMSS?s result. This study based on literature which the PISA and TIMSS study showed Indonesian students? achievement was poor. In the last PISA 2012, Indonesia ranked 64 of 65 participant?s countries, whereas in the last TIMSS 2011, Indonesia ranked 36 of 40. On the contrary, Indonesian students? got a lot of medals in international mathematics contest with a lot of rival countries. Nevertheless, we can?t compare them because of difference test type, but we should have critical thinking about those results. The other reason why we should criticize Indonesian PISA?s result is the sampling used. Why a wider country than Indonesia didn?t used representative sampling in PISA?s test? Why a wider country could participate with just some big cities in there? Was it permitted or by design? Furthermore, the PISA?s sampling which was used in some regions in Indonesia wasn?t representative, for example the samples were the schools belongs to low grade in national exam and accreditation. Moreover, there was lacking in carrying out PISA test, for example language differences and cultural differences can both influence the difficulty level. There was expert?s opinion that questions in different PISA?s test booklet have no function in exactly the same way in different countries, so the questions weren?t reliable at all. Then, was the Indonesian PISA?s result described the true students? achievement? So, it is necessary to criticize the Indonesian PISA?s result.
