Until now student mastery of the material geometry is still relatively low. Many difficulties experienced by students in understanding the geometry of the material, one of which is the difficulty in proving. In addition, the study is not yet available devices that can specifically serve the needs of teachers in the teaching of mathematical proof. Therefore, it is necessary to develop learning tools of proof that can help teachers and train students in the proof of the geometry in school. In this study the evidence used strategy is the strategy of abductive-Deductive. This study aims to develop and produce learning device geometry proof. This type of research is the development of research refers to the model of Plomp through four stages, namely a preliminary investigation stage, the design stage, the stage of realization / construction, and stage of the test, evaluation and revision. This research trials in SMA Laboratorium Unsyiah Banda Aceh. The research showed the average score validator for RPP 4.52, 4.58 LKPD, teaching materials and test 4.54 4.30 learning outcomes, adherence to the 91%, the average score of 3.73 practicality test, 86% students with a positive response, and 80.7% of students complete. This shows that the learning device valid criteria, practical and effective way to improve the geometry of high school students.

Questioning skills is one of the basic skills taught are important to master teachers. Lack of good questioning skills possessed by teachers can lead students in an attention too. This study aimed to describe the questioning skills junior high school teacher in mathematics. This study used a qualitative approach with descriptive research. Subjects in this study are two mathematics teachers from two different schools: one teacher MTsN Matangglumpangdua and one teacher SMP N 5 Peusangan. Qualitative data analysis performed on both the teacher to see the questioning skills of teachers in learning. In general, teachers questioning skills include aspects of pausing, prompting and probing in mathematics has been done, but not all of the indicators on each aspect met for each meeting in both schools. In a study in MTsN during two meetings, at the prompting aspect is not done once the indicator solve the question into several sub-questions of the original question and the probing aspects of displacement indicators do not turn. Furthermore, in a study in junior high school for two meetings, on aspects prompting two indicators do not solve the question into several sub-questions of the original question and review (repeat) information previously provided.

The result of PISA and TIMSS showed that students' mathematics abilities Indonesia is still low, including the ability to think creatively. The ability to think creatively influenced by psychological factors, one of them is anxiety. The efforts that teachers can do to improve creative thinking and coping with anxiety is applying problem posing approach. The problem posing approach can make students creative in issuing ideas to create questions and resolve them through three forms of cognitive activity, namely: presolution posing, within solution posing and posing post solution, then it ramble positive anxiety of students in learning. This study aims to determine the increase in the mathematics creative thinking ability and changes anxiety in learning by using problem posing approach. The study uses a quantitative approach to the type of experimental design pretest-posttest control group. The collecting data by using mathematics creative thinking ability tests and questionnaires anxiety. The data were analyzed using t-test and Two Way Anova. The results showed that the overall increase in the mathematical creative thinking ability of students taught through problem posing approach better than students taught through conventional learning. The same is also happened for students with medium and low KAM. As for students with high KAM increase creative thinking abilities of students taught through problem posing approach is no better than students taught through conventional learning. The results also show that there is no interaction between the learning and human factors to improving the students' ability to think creatively. In addition, overall there is a decrease both anxiety in students being taught by problem posing as well as conventional, as the decrease of anxiety in intention is the decrease of anxiety with ideal criteria. The decrease anxiety in students taught with problem posing better than conventional students. It also happens to students with high and medium.

Peningkatan Kemampuan Pemahaman Matematis dan Motivasi Belajar Matematika Siswa Melalui Penerapan Model Discovery Learning Berbantuan Macromedia Flash 8 Ulfa Nuriza; Saminan Saminan; Zainal Abidin

The purpose of mathematics learning in Permendikbud No. 59 of 2014 requires students are able to understand mathematical concepts, explain the link between concepts and apply concepts or algorithms, are flexible, accurate, efficient, and precise in troubleshooting. But the facts show the students have not been able to understand mathematical concepts well. This condition can be caused by many factors, including students' motivation in learning, models and media used by teachers during the learning process. One model of learning that is presumed to help students to improve understanding and motivation is model of discovery learning aided Macromedia Flash 8. The purpose of this study to determine the increase of understanding mathematical ability and motivation taught with discovery learning aided Macromedia Flash 8 as well as the correlations between mathematical understanding ability and motivation to learn mathematics. This study was an experimental study with pretest-posttest study design group design. The population throughout class XI student of Madrasah Aliyah Negeri 1 Sigli, random sample selection is done to determine the experimental class (XI IPA3) and the control class (XI IPA6). The instrument used in this study consisted of mathematical understanding ability instrument and motivation questionnaire of study mathematics. Based on the results of data analysis using t-test and test of product moment correlation of Pearson gained increased mathematical understanding ability and motivation to learn math through discovery learning model aided Macromedia Flash 8 is better than applying the model of discovery learning but not significant, there is a relationship between the ability of mathematical understanding and motivation through discovery learning model aided macromedia flash 8, the degree of closeness relationship is in enough category.

Student mastery of the basic arithmetic operations of mathematics is still low, especially for students who received school education background before heterogens. This research was conducted to determine the type of error that made the students in doing mathematics basic arithmetic operations, increase students' ability to perform basic arithmetic operations through the implementation of the mathematics matriculation, and suitability scores obtained by students with a score of predetermined targets. This research is a descriptive qualitative research subjects were 27 students of class X SMK 2 Langsa. Data were analyzed using the concept of Miles and Huberman: includes the step of data reduction, data presentation, and conclusion. The results showed that the errors made by the students in solving basic math arithmetic operations are procedural and conceptual errors. Procedural errors do end results is a mistake, an error in the operations of addition, subtraction, multiplication, and division of integers. Conceptual error committed is a mistake to equate the denominator in the operation of addition and subtraction of fractions, simplifying error in root form, and errors in rationalizing the denominator.
