Abstract

Symbolic-Mathematical Thinking is a technique of thinking to solve mathematical problems. This technique is the result of a combination of Symbolic Logic and Mathematics. In general there are three symbolic logic activities that are applied to Mathematics, namely reading symbols, logical equivalents and logical implications.                 This Pengabdian kepada Masyarakat (PkM)  has activities to train Symbolic-Mathematical  thinking using 15 strategies for BOPKRI 2 high school students.                 The results of this training are three important things. The first result is the type of problem that is most difficult for students to face is the type of problem that requires drawing conclusions that refer to standard mathematical definitions. The second thing is for the type of use of model settlement strategies in a system and the type of seeing patterns, students tend to be able to solve problems after being given instructions on how the model fits the problem and the pattern the problem has. Whereas the third is from two groups of students the class turns out that the continuous class attending the training gets more symbolic-mathematical thinking skills improvement than the other classes.

Abstract

Logic is an analysis of methods of thinking. Logic emphasizes the form more than the content of  arguments. mathematical logic is often also called the symbolic-logic is a part of mathematics that explores the application of formal logic to mathematics. This has a close relationship with the basic fundamental thinking of mathematics and theoretical computer science.In this research we do three important things, the first is conventional symbolic-logic training for SLB Negeri 1 Bantul. The second step is making of symbolic-logic learning application for deaf students called DUTAlogic and the third is seeing the comparison between conventional learning and learning using the DUTAlogic.Based on data analysis that was done. Thar result show that increase in symbolic logic ability (T) is 50%, increase in the ability of symbolic natural accuracy (N) is 50%. The used of DUTAlogic application is more attractive to deaf students because they feel happier, easier, more-understanding, more concentrated and more creative when doing symbolic-logic learning.
