This research is a qualitative descriptive research. Research subjects were determined through purposive sampling, and this research was conducted in class X MIA 4 MAN I Bandar Lampung with subject of 6 students divided into 3 groups. The first group consisted of 2 students of type climbers, the second group consisted of 2 students of campers, and the third group consisted of 2 students of type quitters. To determine the type of Adversity Quotient (AQ) of the subject to be selected, the ARP test is used. The data collection technique in this study uses the test method, unstructured interview method conducted on selected subjects and documentation method. Data analysis techniques through data reduction, data presentation, and conclusions. Written test result data is analyzed based on indicators that meet conceptual, semiconceptual, and computational thinking processes. The technique of data validity is done by using triangulation technique comparing data of test result and interview result to subject of climbers, campers and quitters. Based on the data analysis results obtained that the subject with the type Adversity Quotient (AQ) each has a different thinking process. Subjects with type climbers tend to have a conceptual thinking process in solving mathematical problems based on Bransford and Stein theories. Subjects with type campers tend to have a semiconceptual thinking process in solving mathematical problems based on Bransford and Stein theories, and subjects with type quitters in solving problems based on Bransford and Stein theories tend to have a computational thinking process.]]>

<![CDATA[The low ability of mathematical generalization of the students of SMPN 17 Bandar Lampung is because most of the students still have difficulty in drawing a conclusion from the material they have acquired and the lesson learned process of generalization aspect or less precisely the instructional model used. The purpose of this research is to know the influence of learning model of Peer Led Guided Inquiry and learning, discovery learning model with the ability of mathematical generalization. The measured variable from this research is the generalization ability in mathematics learning with the subject of algebraic factorization. This research is a quasi experimental research (quasi experimental research), where the subject of the study is students Class VIII students SMPN 17 Bandar Lampung. Data collection technique used is a test of mathematical generalization ability. The data analysis technique used analysis of variance (ANAVA) of one road with cell unlike the significance level α = 0,05 and as requirement analysis, that is a normal distribution population with liliefors model and homogenous population with Bartlett Test. Based on the result of research using ANAVA one way with cell unequal, hence the decision of Ho test is rejected. So it can be concluded that there is influence of learning model Peer Led Guided Inquiry, learning model of Discovery Learning, Conventional learning model to ability of mathematical generalization of learners. The test proceeds with a double-compression test using Scheffe ' methods to see which has a significant effect on mathematical generabilizability. The calculation results show that of the three treatments, the learning model of Discovery Learning which gives a significant influence on the ability of mathematical generalization.]]>

<![CDATA[The phenomenon that occurs in students is the difficulty of them in detailing and sorting out the division of inheritance. In Islam everything is set up but its application in daily life has not been done with that should be. After the authors delve deeper into this material is indeed difficult to understand, especially in the details of each received by the heirs very closely related to the learning of mathematics in sub-material fractions. Lack of time allocation used in this material, resulting in them not getting examples of varied questions. The method used is qualitative descriptive method. This method tries to describe and interpret what is in accordance with the growing conditions in the ongoing process. Based on the phenomenon that occurred in the field can be concluded that the difficulties experienced by students is to determine the parts that must be accepted by the heirs that have been set in the Qur'an difficult to apply in everyday life, Islam has set clearly in the Qur'an But this has not been done properly. Another difficulty is also experienced in the learning of mathematics is on the equalization pemyebut of fractions obtained by heirs who are too many are entitled to receive inheritance.Keywords: ]]>
