Abstract:Intuition has a big role when the analytic (formal) thinking process does not have the ability to reach it to the problems at hand. The presence of this intuition is spontaneous, immediate and sudden, and sometimes unpredictable. However, its presence is not suddenly but supported by the knowledge and experience, skills and skills possessed, through perceptions and feelings. In this context, intuition serves to facilitate the realm of the mind and makes it easy to understand and solve problems (red mathematical problems) in addition to the role of analytical and formal thinking is also required. Thus, intuition can be a means of opening the gates of ideas or ideas of solution discovery before formal steps are done analytically. The author seeks to illustrate the frameworks of these two forms of thinking (intuitive-analytical) inseparable from one another, but they give benefit from each other in the cycle of mathematical problem-solving.

Abstract:The fact that the low quality of learning and mathematics learning outcomes of students because the majority of math teachers still use the method of learning by way of lectures and assignments. In studying mathematics teachers should pay attention to the process of not only prioritize the achievement of learning results seen from UAS only. Therefore, the learning innovation is required. One of the innovative learning models is the Cycle Learning model. The Cycle Learning model is a student-centered learning model that can motivate students when learning, discussing, explaining, and developing. Thus, it can create an active learning atmosphere and not boring. By using media power point learning process becomes more fun. The research pattern used is quantitative approach and type of quasi-experimental research. The sampling technique used is simple random sampling. The sample used 35 experimental group students and 35 students as control group. Data collection methods used are observation, test and documentation. Data analysis technique using Independent Sample T-test. Based on the result of the research, it is concluded that (1) there is significant effect of cyclic learning model using power point toward student learning result of line material and class VII corner of MTsN Karangrejo Tulungagung. This can be seen from the value of t-test obtained of 3.741 is greater than the value of with a level of 5% that is equal to 1.994. (2) Big influence of learning model cycle using power point to student learning result of line material and grade angle VII MTsN Karangrejo Tulungagung. This can be seen from the value obtained manually that is equal to 0.92 in the interpretation table with 82% percentage.

Abstract:Mathematical communication is the way students express mathematical ideas either orally, written, drawing/diagrams, presenting in algebraic form, or using mathematical symbols. This research is motivated by field fact that shows that the learning process in school has not given opportunity to students to communicate idea related to their understanding. In this case the authors analyze the mathematical communication skills of X-IPA MA superior students Jabal Noor Trenggalek use the indicators on mathematical communication by selecting the subject by purposive sampling as much as 6 students of X-IPA class academic year 2016/2017 high-ability, average, and low. The purpose of this study is to describe the mathematical communication ability of the X-IPA MA superior students of Jabal Noor Trenggalek in solving the mathematical problems of the composition of functional material in terms of mathematical ability. This research uses qualitative approach with descriptive research type. Data were collected by giving tests and interviews. Data analysis is done through data reduction, data presentation, and conclusion. The results showed that the mathematical communication ability of high, medium, and low-ability students fulfilled the 3 components of communication standards established by NCTM, namely: 1) organizing and consolidating their mathematical thinking through communication; 2) analyzing and evaluating mathematical thinking (mathematical thinking) and strategies used by others, 3) using mathematical language to express mathematical ideas correctly.

Abstract:Mathematics is a subject that is considered difficult by students. This assumption is not without reason, because Mathematics is a structured science. If the student does not have a structure, then he will not be able to build a structure on it. Many difficulties are commonly experienced by students in Mathematics subjects. Usually students have difficulties in understanding the concept, application of principle, miscalculation, and less skilled in operation. Researchers chose SMAN I Rejotangan for research. This school is still using the curriculum KTSP when researchers conduct research. This school is easily accessible because it is located on bus lane. In addition, researchers also become educators at this school. Therefore, researchers know very well the atmosphere in this school. When conducting National Exam preparation guidance in class XII, researchers found many mistakes from students when working on root shape issues. While the material of the root form should have been mastered by students since class X. Therefore, there must be something that happens when students are still sitting in the bench class X. For various reasons this researcher want to reveal the reason behind the mistakes of students in working on the form of the root form. Not just to analyze students' mistakes, but also to find out the causes of students making.
