Abstract
Using the real things and engaging the envoiroment in mathematics learning will assist the learners in understanding the concept greatly. The support of learning approaches and assessment model will give a positive impact on learning outcomes of students. Through the experimental research with 2 x 2 design found the results that learning apprroaches and assessment models are dependent each other in affecting the student’s mathematics outcomes. Realistic Mathematics Education (RME) approach is more appropriate to use performance assessment model because it can provide a better impact on mathematics learning outcomes after controlling the early numerical ability of students. While the thematic approach is more appropriate to use the paper tests in mathematics learning.
