Abstract

The purpose of this research is to develop a valid, practical, and effective interactive learning media assisted by GeoGebra. This study used the Thiagarajan (4-D) model which includes four stages, namely defining, designing, developing, and disseminating. The process of the four stages produced an interactive GeoGebra learning media, so students can explore practice questions related to inequalities material independently. The research subjects selected were students of class X Science 2 SMAN Arjasa Jember. The result of this development is a valid interactive learning media assisted by GeoGebra with a very high level of validity, included as practical criteria based on students' scores as media users, and is proven to be effective in improving students' mathematical literacy skills based on the N-Gain from the average pretest and posttest. This interactive learning media assisted by GeoGebra received positive responses from students as an interesting media that support students to understand the material during their sudy.

Abstract

Adult mathematical literacy of high school students rarely gets attention, even though they need this skill to face various life challenges and situations. This research aims to describe the adult mathematical literacy based on activities of mathematical literacy’s processes domain when solving problems. Therefore, three high school students with equivalent mathematical abilities in specialization mathematics and compulsory mathematics are selected as research subjects. Data collection are through tests and interviews. The Data reduced, triangulated using the triangulation method, presented, and used in concluding. The results indicate that high school students with high mathematical abilities can use the ability to formulate situations mathematically, using concept facts, procedures, and mathematical reasoning; and interpret mathematical solutions. However, in formulating the situation, they tend only to identify aspects or components whose value is known by using familiar symbols. They also tend to make mistakes in making mathematical reasoning, especially if the problem involves reasoning with many criteria and conditions, as well as errors in interpreting solutions that contain limitations or constraints. The results suggested to familiarize students with everyday problems that involve reasoning to help students recognize problem situations as mathematical situations and generate creativity in using mathematical knowledge
