<![CDATA[This study aims to analyze the process of abstraction of students of class XI IPA 2 of SMA Negeri 6 Lubuklinggau in understanding the concepts and principles of geometry in terms of Van Hiele's theory. The method used in research is a qualitative method. Data were analyzed through three stages, namely the stage of data preduction, data presentation and conclusion drawing. The results of data analysis obtained from the five steps of thinking based on Van Hiele's theory that the thinking of students of class XI IPA 2 of SMA Negeri 6 Lubuklinggau is only at stage 0 to stage 2, whereas for stage 3 and stage 4 the level of thinking of class XI IPA 2 students Lubuklinggau still has difficulty in drawing conclusions from things that are general to things that are specific and at this stage is also a stage of thinking that is high, complicated and complex. Conclusion, the level of thinking of students of XI Science 2 of SMA Negeri 6 Lubuklinggau is still low in understanding the concepts and principles of geometry in terms of van hiele's theory. Keywords: Geometry Concept, Keori Van Hiele, Abstraction Process]]>

<![CDATA[The purpose of this study was to determine the effect of the SAVI learning model (Somatic, Auditory, Visual, and Intellectual) on the mathematical communication skills of eighth grade students of Karang Dapo State Junior High School 2016/2017 academic year. This study uses the True Experimental Design method (pure experiment) with the research design used is the pretest posttest control group. Data analysis techniques used were normality test, homogeneity test and t-test. The study was conducted in class VIII of Karang Dapo Public Middle School in the 2016/2017 school year. 5 (five) meetings were held, with details of 3 (three) learning meetings, 1 (one) pretest and 1 (one) posttest. Of the 103 students who were members of 4 classes VIII, a random sample was taken with the aim that all classes have the same opportunity to become samples. Based on the results of data analysis with a significant level α = 0.05. The average score of mathematics communication skills of the experimental class students was 25.64 and the control class was 17.02. In conclusion, there is a significant influence of the SAVI learning model (Somatic, Auditory, Visual, and Intellectual) on the mathematical communication skills of Grade VIII students of Karang Dapo Public Middle School.

<![CDATA[This study aims to explain the steps in designing teaching materials in the form of Ethnomatematics-oriented worksheet on SPLDV material. The method used by the author in designing teaching materials is part or two of the initial stages of the ADDIE development model which consists of the analysis, design, development, implementation, and evaluation stages. The results of the study, the concept of ethnomatematics that can be integrated into the form of worksheets, namely, the unit of calculation in the sale and purchase transactions in traditional markets in the form of "secanting and" padembuk ", in addition to the typical Lubuklinggau batik motif in the form of durian motifs. Ethnomatematics context becomes the starting point in the learning process presented in the worksheet on the SPLDV material, so that mathematics learning can be more meaningful. Conclusion, quality Mathematics learning must be supported by various aspects, one of the main aspects is professional teachers who are able to utilize various learning resources and develop teaching materials (LKS) by utilizing the daily cultural context (ethnomatematics) experienced by students, thus the process occurs meaningful mathematics learning and growing awareness of students to appreciate local wisdom and culture in this case the culture of the city of Lubuklinggau.

<![CDATA[This study aims to determine the differences in increasing students' mathematical representation ability and self-confidence in problem based learning (PBM) and ordinary learning (PB). In addition to seeing whether there is an interaction between learning and students' initial mathematical ability (KAM) to increase students' mathematical representation ability and whether students' self-confidence increases. The study population was all students of SMP Negeri 1 Lhokseumawe. The sample of the study was taken randomly by 2 classes totaling 60 students. Data analysis was performed with Two Path ANAVA. The results of the study, students' mathematical representation ability can be known based on the F value on the learning factors (PBM and PB) of 76.4 with a significance value of 0.00 less than α 0.05. While the F value is based on KAM 65.8 with a significance level of 0.00. Conclusion, Improvement of mathematical representation ability and self confidence of students who are given PBM models are higher than students who are given PB, and there is no interaction between learning models and KAM on increasing students' mathematical representation ability, and there is no interaction between learning models and KAM towards increasing self student confidence.

<![CDATA[This study aimed to improve the activity and learning outcome of the eighth grade students of Al-Ulum Islamic school Medan through the TAPPS learning strategy based on STEM education. The research method was a classroom action research as much as two cycles. Each cycle consisted of 4 stages: planning, action, observation, and reflection. The data analysis technique was a descriptive analysis model. Data collection methods were observation and tests. The results showed that the implementation of using the STEM-based TAPPS learning strategy could improve learning activity of the eighth grade student of Al-Ulum Islamic school Medan on the subject of geometry flat side (Bangun Ruang Sisi Datar). This was shown by the percentage of group activity of students in the cycle I was 50.71% or in a good category, the percentage of student group activity in the cycle II was 85.04% or in an excellent category. Thus, the enhancement of students' learning activity using the TAPPS learning strategy based on STEM education could also improve students' learning outcome. This was shown by the percentage of learning mastery in the cycle I was 65,6255% or in the criteria of learning mastery was achieved but it was still classified as low and the percentage of learning mastery, in the cycle II was 90,625% or in the criteria of leaening mastery was achieved. The conclusion of this study is the use of TAPPS-based STEM education learning strategy can improve the activity and learning outcome of students.

<![CDATA[The purpose of this study was to determine the effect of problem-based learning models on the ability to think mathematically creative in class VIII of SMP Negeri 6 Lubuklinggau. This study uses a True Experimental Design approach. In this study the sample used were two classes, namely the control class and the experimental class. The average score of mathematical creative thinking abilities that have been obtained by students on the final test in the experimental class is 19.5517 and in the control class an average score of 14.44783 is obtained. Both classes are normally distributed and homogeneous both on the initial and final tests. The collected data were analyzed using t-test. Based on the results of the t-test analysis obtained tcount = 2.5400 and ttable (at a significant level = 0.05) = 2.001. This shows tcount> ttable, so it can be concluded that there is a significant effect of problem-based learning models on the ability of mathematical creative thinking ability of eighth grade students of SMP Negeri 6 Lubuklinggau. Keywords: Mathematical Creative, Problem Based Learning Model]]>
