<p>The objective of this research was to investigate the effect of Learning model of STAD geogebra viewed from learning style. This research used the quasi experimental research method with the factorial design of 2 × 3. The population was entirely the students 4thof Mathematics Education Program Ma’arif Institute of Metro Lampung in Academic Year 2015/2016. The samples of the research were taken by using the cluster random sampling technique. The size of the sample was 50 students consisted of 26 students in the first experimental class and 24 students in the control class. The instruments to gather the data of the research were test of learning achievement in mathematics and student learning styles questionnaire. The data was analyzed by using the two-way analysis of variance with unbalanced cells. The conclusionsof thisresearchwere as follows. (1) The cooperative learning model of STAD Geogebra type resulted in a better learning achievement in mathematics than the Powerpoint-assisted direct learning model. (2) Students with visual learning style have the same achievement with students with auditory learning styles. Students with auditory learning style have the same achievement with students with kinesthetic learning styles. Students with visual learning styles have a better academic achievement than students with kinesthetic learning styles. (3) Difference in achievement of each learning method was not consistent with their respective learning styles and differences between individual learning style also was not consistent in each learning method</p> <p>Keywords: geogebra, power point, Student Team Achievment Devisions (STAD)</p>Wawan wawan

This study aims to describe the Lampung handicraft "tapis and siger" into learning mathematics at Elementary School level. The data obtained in the form of qualitative data while the source obtained from observations, documentation and informants associated with Lampung handicraft the "tapis and siger". The instrument in this study is the researcher itself. The tools used are interview guides, documentation guides, and observation guidelines. Data validity technique by data triangulation through data source checking, analizing descriptive qualitative. The results showed that the motif of woven cloth fabric Sanggar Rahayu consists of geometric motifs, humans, animals, and motifs of plants, while Siger Lampung has a mathematical element in which the triangle. Cultural-based math learning is needed in schools especially in elementary school, because not only to understand the concept of mathematics but learners are also introduced and love culture early on.Rizki Wahyu Yunian Putra, Popi Indriani

http://journal.iaimnumetrolampung.ac.id/index.php/numerical/article/view/119
Abstract Thinking mathematically is a way of thinking in accomplishing the task of mathematics both simple and complex. The things that happened in this research, learners less like math lesson, lack of patience of educator in guiding learners, and model of lesser learning that can cause low mathematical thinking ability of learners. Thinking mathematically in Bloom's taxonomy is important to improve low-level thinking to high-level thinking to solve fundamental problems to complex in mathematics. the aims of this study ie to determine think mathematically based on Bloom's taxonomy revision by using the model of learning attention, relevance, confidence, and satisfaction (ARCS) is better than using a conventional learning model. The sampling technique by purposive sampling. The validity test of the instrument using product moment formula. Reliability of test instruments using Alpha formula. The prerequisite test of variance analysis is liliefors test to know normality and Bartlett test to know homogeneity, then for hypothesis testing by t-test.Resti Yelma Sari, Netriwati Netriwati, Fraulein Intan Sari

http://journal.iaimnumetrolampung.ac.id/index.php/numerical/article/view/120
The objective of this research was to investigate the effect of analytical on learning achievement viewed from IQ. This research used the causal comparative research with the factorial design of 3 x 3. Its population was all of the students of mathematics education in Islamic Institute Of Ma’arif NU Metro Lampung. The samples of the research were taken by using the random sampling. The instruments used to gather the data of the research were test of learning achievement in Mathematics, test of analytical individu and test of IQ of the students. Prior to their use, both the test were tried out. Their contents were validated by the related experts. The reliability of the instruments was tested by using the Cronbach Alpha formula. The discrimination power of the test and the internal consistency of the questionnaire used Karl Pearson’s product moment correlation formula. The pre-requisite tests of the research included the normality test by using Lilliefors test and homogeneity test by using Bartlett test. The proposed hypotheses of the research were tested by using the two-way analysis of variance with unbalanced cells. The results of the research are as follows. 1) The students with high IQ have a better learning achievement in Mathematics than students with moderate IQ. 2) The students with the high analytical individu have a better learning achievement in Mathematics than those with the moderate and low analytical individu, and the students with the moderate analytical individu have a better learning achievement in Mathematics than those with the low analytical individu. 3) There was interaction among analytical and IQ on learning achievement mathematics.Agus Setiawan

http://journal.iaimnumetrolampung.ac.id/index.php/numerical/article/view/121
This research aims to determine what kind of mistakes made PGMI students even semester of the academic year 2016/2017 in solving the problem of compound statement negation on mathematical logic and to know the alternative solution. The type of this research is descriptive research with qualitative approach. The research instrument used in this research is mathematical logic test and interview. The data analyzed is the result of student work on the worksheet that made a mistake. The results of this study indicate that students experience some errors that are marking errors, mistranslate logic symbols, concept errors, mistakes remembering the truth value in the statement truth table, and error concluded. After knowing the types of mistakes made by students in working on the question of negation of compound statements, then the alternative solution that can be given to this research problem is to use learning techniques that enable students to think well Like discussing, speaking and writing in front of the class to explain Directly so that students can retain their memories much longer, emphasizing the importance of much work on the matter by watching the right symbols or practicing remembering and writing symbols through the questions, giving repetitive exercise of different types of questions, and routine assignments To be memorized by truth values in mathematical logic.Mutia Mutia

The process of thinking is the steps that a person uses in receiving, processing, concluding, and reusing the information obtained to resolve the issues related to solve the problem of the memory. While cognitive style is an activity that became a characteristic of learners in the functioning of mental activities in the field of cognitive (thinking, remembering, processing information, organizing, solving problems, and making decisions) which is consistent. Cognitive style has a major role when utilized in an effort to improve the effectiveness of the learning process. Cognitive styles are divided into two, namely, Field Independent (FI) and Field Dependent (FD). This research is descriptive qualitative which describes the process of thinking of students in solving mathematical problems on material combinations and permutations. The data collection method in this study using GEFT tests to determine cognitive styles of students, test description of material combinations and permutations to obtain the thinking process of students, and interviews. Based on cognitive style, students are grouped into 2 groups: FI and FD, and then subsequently selected two students from two groups of students from the FI and FD to give test of thinking ability and then interviews. Data analysis technique used Miles and Huberman, data reduction, display, and conclusion drawing / verification. Based on the analysis we concluded that students who have the cognitive styles FI tend to have a conceptual thought process. Likewise, students who have the cognitive style FD, these students are also likely to have a conceptual thought process. The process of conceptual thinking is the thought process which solves problems by using the concept that has been owned by the results of studies.Ardi Dwi Susandi, Santi Widyawati
