CRITICAL AND LOGICAL MATHEMATICS THINKING SKILLS ENHANCEMENT OF VOVATIONAL SCHOOL STUDENTS THROUGH COOPERATIVE MODEL TYPE STAD ASSISTED MAPLE
Critical thinking skills of mathematics and mathematical logical thinking is very important in the study of mathematics, as described in 2013 curriculum books that are currently implemented. However, this ability is often overlooked in the study of mathematics which still adhered to the old paradigm that learning is less engaging students in active thinking so that students are not used to empower the cognitive function in thinking. One of the efforts to develop the students' active thinking on the matter exponent especially needed an innovative learning strategies that STAD learning model aided Maple. This study aims to determine the increase in critical thinking skills and logical mathematical learning mathematics students getting through the cooperative model STAD assisted Maple. This research uses experimental methods to study the design of the control group pretest-posttest design. Population is the entire class X SMK Flight Banda Aceh by taking two classes as a sample of the experimental class and control class, through random sampling technique of three parallel classes are available. Data collection was performed using a test instrument that includes tests of critical thinking and logical ability. To see the difference in ability between groups of students Student Team Achievement Division with a conventional group used the t-test at a significance level of 0.05 after testing pre-requisites are met. Based on the results, it is noted that: 1) Improvement of critical thinking skills of students who got the mathematical learning of mathematics through STAD cooperative model assisted Maple is better than the students who received conventional learning, in terms of: (a) overall, and (b) subgroup ( high, medium, low); 2) Improvement of mathematical logical thinking ability of students who receive mathematics learning through cooperative model STAD assisted Maple is better than the students who received conventional learning, in terms of: (a) overall, and (b) subgroups (high, medium, low).
