The students mathematical understanding is important to master. Mathematical understanding is also one of the goals of each material presented by the teacher, because the teacher is a guide to achieve the expected concept. Although already has the ability of a mathematical language is needed, but the belief in the field of this ability is still not fully reinforced by students. This study aims to examine the comparison of the ability to understand mathematically students who apply Algebrator software-assisted learning and students who use regular learning and examine differences in the ability to improve students mathematical understanding of Algebrator-assisted learning software and students using ordinary learning. The research method used in this research is quasi experiment with non-equivalent control group design (unequal control group design). The result of hypothesis test shows that there is a difference in the ability of understanding of mathematics significantly between the students with high, medium and low ability level. This is possible by the improvement of mathematical ability of students triggered by Algebrator software-assisted mathematics learning which in the implementation of learning always pay attention to students centered

The research is purposed to generate aÂ learning trajectory that supports students to understand the concepts of exponential through the context vegetative propagation in animals. The Design Research was chosen as the exact method to achive the objective. Hypotetical learning trajectory in the design research played an important role as the design and research instrument. Hypotetical learning trajectory was designed as the preliminary design and was examined to 50 students from the ninth graders of YPI Tunas Bangsa Junior high school.Â (e.g 6 students from pilot experiment and 44 students from teaching experiment). The result of the learning experiment showed that drawing activity of the process of animal vegetative propagation could motivate the students to see the form of the animal multiplication. While seeing the animal multiplication through modeling (scheme, chart, and diagram), the students had an idea to calculate new animals had been formed, and used multiple numeral to determine the sum of the new animals. From the multiple numeral, an idea to state it in terms of repetitive numeral would bring the students into a definition of exponential. Based on the result above, its suggested that context containing multiplication form be used, let the students see multiplication, and the students do it mathematically into the basic concept when they are learning exponential.
