Abstract:The objective of the study was to know the influence of missouri mathematic project model based open-ended questions toward students' mathematics communication ability. The population of the study was all seventh graders of SMP Negeri 8 Lubuklinggau in academic year of 2018/2019 meanwhile the sample of this study was selected randomly. The data collection used two essay tests namely pre-test to know students' mathematic ability before following learning process and post-test after following learning process. The data analysis used normality test, homogeneity test, and t-test. Based on t-test analysis result with α = 0.05, found that t-value>t-tabel (6,92> 1,67), so it can be concluded that there is influence of learning model of missouri mathematic project based on open-ended questions toward students' mathematic communication ability of seventh graders of SMPN 8 lubuklinggau.

Abstract:This study aimed to (1) describe students' creative thinking skills during the learning process by using PBL model, (2) find out the improvement of students' creative thinking skills after using the PBL model, and (3) describe student learning independence during the learning process by using PBL model. This study uses mixed method research with concurrent embedded strategy. The sample was selected by random sampling, namely students of class VIII-3, which were consisted of 28 students from all eighth grade of SMP Negeri 16 Banda Aceh. The instruments in this study were daily description test, observation and questionnaire. These instruments were used to obtain data of the improvement of students' creative thinking abilities after using the PBL model were pre-test and post-test, and also the instruments which were used to describe student learning independence during the learning process by using PBL model. The result of data analysis in the daily description test and observation used the assessment rubric of creative thinking skills with qualitative descriptive method. Pre-test and post-test results were analyzed by statistical test using SPSS version 22 software for Windows, and the results of the learning independence questionnaires were analyzed by using a Likert scale and percentage. The result of the study showed that students are creative in solving problems related to the comparison during the PBL model in learning process. Thus, there was an improvement in students' creative thinking skills after using PBL learning model. The result of this study also showed that students have learning independence during the PBL model in learning process. Keywords: Problem Based Learning Model (PBL), Creative Thinking Ability, Learning Independence.

Abstract: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.

Abstract:The purpose of this study was to determine the effect of problem-based learning models on mathematical creative thinking abilities of eighth grade students of SMP Negeri 6 Lubuklinggau. This study used the True Experimental Design. In this study, the samples used were two classes, namely the control class and the experimental class. The average score of mathematical creative thinking skills that had been obtained by students in the final test in the experimental class was 19.5517 and in the control class was 14.4783. Both classes were normally distributed and homogeneous both at the pre-test and the post-test. The data collection was analyzed by using the t-test. The results of the t-test analysis were t-value = 2.5400 and t-table (significance level α= 0.05) = 2.001. This showed that t-value> t-table, so it can be concluded that there is a significant effect of problem-based learning models on mathematical creative thinking abilities of eighth grade students of SMP Negeri 6 Lubuklinggau. KeyWord: Problem-based, creative mathematical learning model

Abstract:This study aimed to determine the difference in the improvement of students' mathematical representation ability in problem-based learning (PBL) and regular learning as well as to determine the difference in the improvement of students' self confidence in PBL and regular learning. In addition, to find out whether there was an interaction between learning and students' early mathematical ability toward the improvement of students' mathematical representation ability and whether there was an interaction between learning and students' early mathematical ability toward students' self confidence. The population was all students of SMP Negeri 1 Lhokseumawe. The sample was taken randomly as many as 2 classes which were consisted of 60 students. Data analysis was conducted by using Two way ANAVA. The conclusion were (1) the ability improvement of mathematical representation of students given a PBL model was higher than students given regular learning. (2) the improvement of students' self confidence given a PBL model was higher than students given regular learning. (3) There was no interaction between the learning model and students' early mathematical ability toward the improvement of students' mathematical representation skill. (4) There was no interaction between learning model and students' early methematical ability toward the improvement of students' self confidence. Keywords: Problem based learning model, regular learning, mathematical representation, and self confidence.

Abstract:This study aims to explain the steps in designing teaching materials in the form of LKS oriented Etnomatematics on SPLDV material using the first two stages of the ADDIE development model. The method used by the writer in designing teaching materials is a part or the first two stages of the ADDIE development model which consists of the stages of analysis, design, development, implementation, and evaluation. The analysis stage aims to identify the curriculum, student characteristics, the need for instructional materials, while the design stage is to design the LKS framework and research instruments. The results of the study are ethnomatematics concepts that can be integrated into learning by presenting in LKS, namely, the unit of calculation in buying and selling transactions in traditional markets in the form of "secanting and setembuk ", besides that Lubuklinggau's typical batik motif is durian motif. The ethnomatematics context becomes the starting point in the learning process presented in the LKS on SPLDV material, so that mathematics learning can be more meaningful. In Conclusion, a good quality of Mathematics learning must be supported by various aspects, one of the main aspects is professional teacher who is able to utilize various learning resources and develop teaching materials (LKS) by utilizing the daily cultural context (ethnomatematics) experienced by students, thus the process of meaningful mathematics learning occurs and grows awareness of students to appreciate local wisdom and culture in this case the culture of Lubuklinggau.
