Recent Development of Authentic Assessment to Improve Students' Mathematical Problem Solving Ability

This study tries to find out how to develop an authentic assessment based on its principles and characteristics, and how to apply the assessment to improve students' mathematical problem solving abilities. This study uses research and development methods by carrying out the following stages: 1) needs analysis, 2) literature review, 3) pre-test, 4) designing an authentic assessment form, and 5) conducting a post-test to determine the value of mathematical problem solving ability. The research findings reveal that the stages of developing authentic assessment through a limited validation process and wider validation based on the principles and characteristics of authentic assessment are able to produce new products and their application can have an effect on increasing students' mathematical problem solving abilities. The effect of the application of authentic assessment products resulting from the development process is known from the mean pre-test and post-test, as well as the significance value of the t-test results for interconnecting samples of 0.000 which is smaller than 0.05.
