Abstract

Realistic approach is a learning approach that examines topics / concepts of mathematics through contextual problems. The goal is to create a memorable and meaningful learning through experience. This mathematical experience gained from the experience of mathematics. The experience can be obtained from the culture. Etnomatematika is a form of mathematics were influenced or based on the culture that exists in the community, either in the form of religion, artifacts and customs. One etnomatematika that develops in the people of Aceh and close to the students is about science faraidh (the division of the estate). Faraidh etnomatematika utilization of science is in accordance with the purpose of education in Aceh that are nuanced Islamic education as an area that bersyariat Islam. However, etnomatematika-based learning tools that are not available, so it needs to be an effort to help teachers to develop devices based learning etnomatematika. This study aims to determine the process and outcome-based learning software development etnomatematika valid, practical, and effective. The development method used for unmet valid, practical and effective is the method Plomp, which includes the initial assessment phase, the design / prototyping, and assessment. The subjects were a group of junior high school students in grade VIID Al-Fityan IT as a subject limited test and one class graders from junior IT VIIB Al-Fityan Aceh Besar as subjects to test the practicalities and effectiveness of the learning. The results of this study obtained etnomatematika based learning tools that meet the criteria for a valid, practical, and effective.

Abstract

In the curriculum informatics engineering program of South Aceh Polytechnic, functiom derivative is taught in the second semester. The derivative function is a mathematics concept who does manipulation toward a function, thus the function slope can be obtained quantitatively on the slanted point. The derivative function material is one of the difficult material faced by the students. Accordingly, the implementation of a learning model is a good thing to create students' interest on the subject. And  the media also use to support teaching and learning process as software maple. The purpose of this research is to find out the students? results who have taught by quantum teaching and also maple on derivative function and the students who have taught by conventional method, and also to know the students' responses after taught by quantum teaching and software maple on derivative material. Experimental method is used in this research by designing pre-test and post-test and control groups. The population is all  of the second semester informatics engineering's students at South Aceh Polytechnic where they divided into two classes. The technique in gaining data is using two tests, they are written and questionnaire test. The result of data is analyzed by T-test, and questionnaire is analyzed by calculating the average scores which have set by Likert-scale. Research found that t-score > t-table that is 2.41>1,69. This showed that, the students' score on derivative material taught by quantum teaching by adopting media maple is better than the students' score taught by conventional method at informatics engineering of South Aceh Polytechnic. As for the students' responses, gainned the average of a proposed statements is 3.52. According to the specified criterias, the researcher concludes that the students' responses toward the implementation of quantum teaching by software maple on derivative function is very positive.

Abstract

Research is included into the type of descriptive study using quantitative and qualitative approaches. The research procedure includes stage 1) initial observation, 2) preparation, 3) implementation, 4) evaluation, and 5) final results. The subjects in this study were the second semester students of Mechanical Engineering Study Program, totaling 24 people. Data collection techniques used 1) test questions, 2) interviews, 3) documentation, and 4) field notes. Data analysis techniques mastery level of the material were analyzed using the percentage formula. Interview data were analyzed in stages 1) reducing data, 2) presenting data, and 3) summarizing data. Instrument documentation and field notes were analyzed narratively. The results of data analysis on the level of student mastery of composite material shows that the group of students in the category of mastery is very mastering (SM) 0 students (0%), the category of mastery mastering (M) is 9 students (23.68%), the category of mastery is less mastering (KM ) 16 students (42.11%), mastery category not mastered (TM) 13 students (34.21%). Students who mastered the mastery-1 category were 15 students (39.47%), who mastered the mastery-2 category by 22 students (57.89%), who mastered the mastery-3 category by 9 students (23.68%) and categories mastery-4 as many as 0 students (0%). Interview results obtained by some students 'mistakes in mastering composite material courses, namely a) errors in the use of formulas or concept errors, b) errors in algebraic fraction operations, c) students' lack of attention to the tests conducted, d) errors in inputting parameter values, e) errors in the operation of exponential numbers, f) errors in formulating problems in the form of formulas (mathematical modeling), and g) principle errors.
