The development of mathematical HOTS questions based on banten culture

Abstract

The resulted of a survey conducted by the Organization for Economic Cooperation and Develop-ment based on the 2018 Program for International Student Assessment were obtained from 78 countries, Indonesian students ranked 72nd in math ability. The reason is that the 2013 curricu-lum that has been implemented in Indonesia is eurocentric. The transformation sought in the field of education is the improvement of high order thinking skills and mathematical abilities. Educa-tion and culture cannot be separated from regular daily life because culture covers all aspects of life while education is a primary need for everyone. This study used the Research and Develop-ment (R&D) method with the Martin Tessmer (1993) model, which is formative research.  The validity of the values obtained above 0.80 means that the questions are valid. The level of practi-cality of the questions obtained is 96.25%, very practical category. The reliability coefficient of 0.891, reliable. The level of difficulty is known to be 80% of the items in the medium category, 20% of the items in the difficult category. The discriminatory power of the question is known to all items (100%) in good category, meaning that good questions are used to classify the level of stu-dents thinking abilities.
