Abstractâ This study aimed to determine students responses toward the development of student worksheet with problem based learning model in the comparison material. This study used 4-D model of development that consisted of four stages, namely the definition, design, development, and disseminate. Data collection instruments were sheets of validation and questionnaire of studentsâ responses. The questionnaire of studentsâ responses used Guttman scale consisting of 20 items of positive and negative statements. Grain statement was based on the aspects of accuracy, conformity with learning models, as well as the fulfillment of the terms of didactic, construction, and technical. Before tested to students, the student worksheet has been validated by three experts on mathematics education with very valid results (3.73). The student worksheet trial conducted to 32 students of class VII-1 SMPN 1 Kuantan Mudik, Kuantan Singingi, Riau Province during the second semester of the academic year 2016/2017. After carrying out learning by using worksheets, students were given the response questionnaire. Overall, students gave a positive response to the student worksheet which amounted to 94.37% categorized as very practical. Although the student worksheet already using Indonesian referring to Spelling Enhanced, there are some students who think that they find the unknown word or term on student worksheet. However, this is not a significant obstacle in learning because the student worksheet was developed for group learning so students can discuss things they did not understand with their group members. Â Keywords: problem based learning, studentsâ response, studentsâ worksheetÂ Abstrak. Penelitian ini bertujuan untuk mengetahui respon siswa terhadap Lembar Kerja Siswa berbasis Problem Based Learning yang dikembangkan. Pengembangan menggunakan model 4-DÂ yang terdiri dari 4 tahap yaitu Definition, Design, Development, dan Disseminate. Pengumpulan data menggunakan lembar validasi dan angket respon siswa.Â Angket respon siswa menggunakan skala Guttman yang terdiri atas 20 item berisi pernyataan positif dan negative. Item pernyataan didasarkan pada aspek akurasi, kesesuaian dengan model pembelajaran, serta pemenuhan syarat didaktik, konstruksi, dan teknis. Sebelum diuji kepada siswa, lembar kerja siswa divalidasi oleh tiga ahli pendidikan matematika dengan hasil yang sangat valid (3,73). Uji coba lembar kerja siswa dilakukan kepada 32 siswa kelas VII-1 SMPN 1 Kuantan Mudik, Kuantan Singingi, Provinsi Riau pada semester II tahun akademik 2016/2017. Setelah melakukan pembelajaran dengan menggunakan lembar kerja, siswa diberi angket respon. Secara keseluruhan, siswa memberikan respon positif terhadap lembar kerja siswa yang berjumlah 94,37% tergolong sangat praktis. Meskipun lembar kerja siswa sudah menggunakan bahasa Indonesia yang mengacu pada Ejaan yang Disempurnakan, ada beberapa siswa yang menemukan kata atau istilah yang tidak diketahui pada lembar kerja siswa. Namun, ini bukan masalah karena lembar kerja siswa dikembangkan untuk pembelajaran kelompok sehingga siswa dapat mendiskusikan hal-hal yang tidak mereka mengerti dengan anggota kelompok mereka.Â Keywords: problem based learning, studentsâ response, studentsâ worksheet

Abstract: This study aims to improve the learning process and the student’s mathematical understanding skill by applying Discovery Learning (DL) model. This research is Classroom Action Research with two cycles. This research was conducted in class X science 2 MAN 1 Kuantan Singingi in the second semester of academic year 2017/2018 to 27 students. The required data are qualitative and quantitative data. The research instruments used are mathematical learning instruments (Syllabus, Lesson Plans, and Student Activity Sheets) and instruments for collecting data (Observation Sheets and Mathematical-Understanding Tests). Qualitative data were collected by observation technique and analyzed by descriptive narrative analysis. Quantitative data were collected by test technique and analyzed by descriptive statistics analysis. Based on the analysis of the observation sheets showed that implementation of learning process on cycle II had happened improvement from implementation on cycle I. Weakness on cycle I is improved on implementation cycle II according with planning of improvement after reflection cycle I. Result of the test indicates that the student’s learning achievement for the first is 40,4 improved in cycle I to 60,2 and improved to 89.62 in cycle II. The improvement of student’s learning achievement founded for each indicator of mathematical understanding skill: redefine the concept, provide examples and not examples the concept, and applying concepts to solve the problem. This study concludes that the implementation of DL improved the learning process and the student’s mathematical understanding skill at class X science 2 MAN 1 Kuantan Singingi in the second semester of academic year 2017/2018.Key Words: discovery learning, mathematical understanding skill, learning process

This study aimed to determine the mathematical literacy (reasoning and communication of mathematics) of junior high schoolstudents in KecamatanTampan Kota Pekanbaru in geometry. The research instrument used instruments PISA 2012 with space and shape content translated into Indonesian. Overall, the test consists of 14 items with the nine themes. The population in this study are student at class IX of SMPN 20 and SMPN 23 Pekanbaru. Randomly selected one class from each school in order to obtain a sample of 74 people. The results showed that students mathematical literacy is still low with an average score of 46.90 and a standard deviation of 15.15. For aspects of mathematical reasoning abilities, students tend not able to use patterns and relationships to analyze mathematical situations, provide explanations using models, facts, attributes, and relationships, as well as estimating the answer and the solution process. For aspect of communication, students tend not able to connect real objects, drawings, and diagrams into mathematical ideas.

This research aimed to analyze the studentsâmistakes based on Newman error analysis. Newman Error type consists of reading error, understanding the mattererror, the transformation error, processing skillserror, and writing down the answers errors. Qualitative research uses to descriptive describe the symptoms or the circumstances of the students in solving the matter on integral application. The research was conducted in the S-1 Study Program of Mathematics Education in 2017/2018 with the subject as many as 6 students who have low, medium and high competency respectively 2 students. The researcher gave two questions about the application integral to the students and then the results were analyzed and interviews were conducted to obtain information on students errors in solving problems.The analysis result shows that studentswith low competency experienced in reading error, comprehension error, transformation error, process skills error, and encoding error. This is because the students do not really understand the integral application materials. The students with medium competency in an underwenterror in process skills and writing the final answers. While the high-competence students had an error in writing the final answer. Overall, most students experienced errors at the stage of understanding the problem. This happens because the students do not read and understand the questions carefully so the students are not able to understand the matter. In the end the students make mistakes of writing down the answers
