The purpose of this study is to produce student worksheets (LKS) that are validity and practical, and have potential effects on student learning outcomes. The method in this study uses the modified Dick and Carey development method. LKS developed valid based on expert and practical response questionnaires based on student response questionnaires. The potential effects of LKS developed can be seen from the activities of students in working on the questions on the LKS, where students more easily understand the mathematical concepts contained in the LKS and use the concepts appropriately in solving the problems given. The results of the study Of the 23 students who were the subjects of the study obtained 11 people were in the excellent category or around 47.82%. Whereas there are 5 people in katerogy or around 21.73%, enough categories are obtained by 4 people or around 17.39% and the poor category is obtained by 3 people or around 13.04%. It can be concluded that LKS designed using a realistic Indonesian mathematical approach based on the context of South Sumatra has a potential effect on student learning outcomes.

The objectives of this research are: 1) produce a valid and practical pocket book of building material based on realistic mathematical education approach (RME), 2) know the potential effect that arises from developing pocket book of building material of flat side space, 3) knowing the student's response to pocket book material of building flat side space. Development of pocket book is done through two stages of priliminary stage (preparation) and formative evaluation stage. The results of this study show that pocket book wake up flat side space using RME approach that produced valid and practical. Valid is reflected from the revision after being validated by an expert based on content, constructs, and language. Based on the document analysis of the work result of the students during field test, showed the final test of learning using Pocket book with RME approach get very good category 43,75%, good 28,12%, enough 15,62%, and less 12,5%, data result the test is that the learning done shows a good potential effect. Based on analysis of student response result to pocket book developed for indicator of interest in pocket book obtained 86,09% student express strongly agree, material indicator 79,97% student agree and indicator from linguistic side 89,32% student strongly agree Keywords: Pocketbook, PMRI
The purpose of this study was to develop student work ethics-oriented student worksheets based on guided discoveries on the material of flat side space and to find out the quality of worksheets developed in terms of validity, practicality and potential effects. The method, this research is Research and Dependency (R&D), that is development research that refers to a modified 4-D development model. The instruments used to measure the quality of worksheets developed include validation sheets, practicality questionnaires, walkthroughs and tests. Worksheets that are developed are valid based on validation sheets by experts and are practical based on a practical questionnaire. The potential effects of worksheets developed can be seen from the activities and understanding of students in working on the problems given to the worksheets. The results showed that: (1) the quality of worksheets seen from the aspect of validity included in the valid category with an average score of 3.18; (2) the quality of worksheets seen from the practical aspect is categorized practically with an average score of 3.24; and (3) worksheets have a potential effect on student learning outcomes where 20 students (76.9%) are included in the category of completion while there are 6 students (23.1%) have not been completed with the Minimum Learning Completion (KBM) specified. Conclusion, ethnomatematics-oriented worksheet based on guided discovery developed is declared valid, practical and potential in improving student learning outcomes in the material of flat side spaces.

Learning trajectory merupakan alur pemikiran siswa yang dihasilkan dari Hypothetical learning trajectory (HLT). Learning trajectory yang dihasilkan pada pembelajaran materi luas permukaan kubus dan balok dapat dijadikan dasar bagi guru dalam mengembangankan model, metode serta bahan ajar yang akan digunakan dalam pembelajaran. Metode penelitian yang digunakan adalah metode penelitian design research yang bertujuan mengembangkan local instruction theory melalui kerjasama antara peneliti dan guru dalam meningkatkan kualitas pembelajaran. Metode design research terdiri dari tiga tahapan yaitiu pre experimen, teaching experiment dan restropective analysis. Teknik pengumpulan data yang digunakan dalam penelitian ini adalah dokumentasi, wawancara dan observasi, dan tes. Data yang diperoleh selanjutnya dianalisis secara deskriptif. Analisis data hasil dokumentasi, wawancara, observasi, dan tes dilakukan secara kualitatif.
The purpose of this study was to develop student worksheets (LKS) using the Lubuklinggau city-based Contextual Teaching and Learning (CTL) on the set material in class VII according to the 2013 curriculum and find out the quality of worksheets developed from the validity, practicality and potential effects of using LKS. The research method used is Research and Development (R&D) research. Development of worksheets using a 4-D model that was modified to a 3-D model. This model consists of 3 stages, namely: the stage of defining (Define), design (Development) and development (Develop) without including the spread (Disseminate) due to time constraints. The results of the study are based on the assessment analysis by the three experts namely: linguists, material experts, and media experts showing that the worksheet fulfills valid criteria with an average score of 3.12. While the results of the analysis of student response questionnaire assessments obtained that the student worksheets meet practical criteria with an average score of 3.55 and have a potential effect of 27 students (84.37%) whose grades reach mastery learning, while 5 students (15.63%) not reached mastery learning. In conclusion, the development of student worksheets using the contextual Teaching and Learning (CTL) based on the city of Lubuklinggau is declared valid, practical and has a potential effect on students' mastery learning.
