Indonesia's PISA test results in the last three periods still rank in the bottom ten. This shows that the mathematics ability of Indonesian students is still low. This research aims to explore the higher order thinking processes experienced by junior high school students in solving PISA questions before and during scaffolding. This research was conducted at SMP Negeri 3 Singosari, Malang Regency, in the form of giving tests to 31 students of class IX, interviews and scaffolding. Scaffolding is done in order to complete the unfulfilled aspects in the phases of thinking. From this research, it was found that: (1) The high-level thinking process of students in solving PISA questions, before scaffolding has included the three phases that must be passed (the entry phase, the attack phase, and the review phase), but not all aspects of each phase are fulfilled; (2) Scaffolding has helped students in solving PISA questions. Improve the teacher's ability to do scaffolding to help students find aha! with more attention to the obstacles (stuck?) faced by students

Hasil tes PISA Indonesia dalam tiga periode terakhir masih menempati posisi sepuluh terbawah. Hal ini menunjukkan bahwa kemampuan matematika siswa Indonesia masih rendah. Penelitian ini bertujuan untuk mengeksplorasi proses berpikir tingkat tinggi yang dialami siswa SMP dalam menyelesaikan soal PISA sebelum dan saat scaffolding. Penelitian ini dilaksanakan di SMP Negeri 3 Singosari, Kabupaten Malang, berupa pemberian tes kepada 31 siswa kelas IX, wawancara dan scaffolding. Scaffolding dilakukan dalam rangka melengkapi aspek-aspek yang belum terpenuhi dalam fase-fase berpikir. Dari penelitian ini diperoleh bahwa: (1) Proses berpikir tingkat tinggi siswa dalam menyelesaikan soal PISA, sebelum scaffolding telah memuat ketiga fase yang harus dilalui (fase entry, fase attack, dan fase review) tetapi tidak semua aspek pada setiap fase terpenuhi; (2) Scaffolding telah membantu siswa dalam menyelesaikan soal PISA. Tingkatkan kemampuan guru dalam melakukan scaffolding untuk membantu siswa menemukan aha! dengan lebih cermat terhadap kendala (stuck?) yang dihadapi siswa.

This research development aims to produce a learning device characterized by valid guided discoveries. The development of learning tools refers to the Thiagarajan, Semmel, and Semmel (1974) model, which is the development of Four-D, which is modified into Three-D. This development model consists of 3 stages of development, namely define, desig, and develop. Assessment of the quality of learning tools in this study consisted of evaluating validity. Learning tools are said to be valid if according to the judgment of experts and practitioners have content validity and construct validity. From the development results obtained learning tools (learning media, lesson plans, and mastery test material) quadratic function material characterized by guided discoveries, can be categorized valid. Based on the results of the development of learning tools obtained that the learning tools (learning media, lesson plans, and mastery tests of materials) are categorized valid in a row that is 3.05; 3.1; 3.1 and have met the specified criteria.Keywords: development, learning tools, guided discovery, quadratic functions

to identity the types of errors made by students to solving the problem of quadratic equations in SMK Kartika IV-1 Malang. Research method used is qualitative descriptive research. Subject in the research were 3 students with low, medium, high mathematics ability category. Based on the analysis of obtained can be concluded that studen make conceptual errors, procedural errors, and computation errors. For example factor causing the students to make errors are the students less mastered and understand the matter about quadratic equations, students are less thorough the problem and student not understand step by step to solving problem of quaratic equations.

The facts show that there are still many students who make mistakes in solving fraction story questions. The research objective was to identify and analyze student errors in solving fraction story questions. This type of research is a qualitative descriptive study. The research subjects were three grade VII junior high school students who were all girls. Subjects were given two tests of fraction story questions. This research was started from August 2016 to January 2017. The test answer sheets were identified, then analyzed. The results showed that almost all the errors of Newman procedure were carried out by the subject, namely: (1) reading (2) understanding (3) transformation errors (4) skills skills and (5) layout and different intensity of errors for each subject. Causes: (1) reduced verbal ability (2) low algorithmic ability (3) error prerequisite material (4) accuracy (5) lack of desire to solve questions.Keywords: story problem, fraction, Newman procedure

The ability of geometry is an aspect that underlies students to solve geometry problems. Several studies have stated students' difficulties in learning geometry. There are five levels of expansion of Van Hiele's theory, namely level 0, level 0.5, level 1, level 1.5, and level 2 which are used to measure the geometry abilities of junior high school students. Students' low geometry skills can be improved through scaffolding, so an appropriate scaffolding design is needed. This study aims to describe the appropriate scaffolding design based on the geometry ability test of junior high school students in terms of the expansion of Van Hiele's theory. The research subjects in this study consisted of 3 students of class VIII of SMP Negeri 8 Malang divided into 3 different levels of geometry ability, namely level 0, 0.5, and 1. Data collection methods consisted of written tests and interviews. The results showed that students at level 1 needed scaffolding to be able to connect the properties between quadrilateral shapes. Students at level 0.5 require scaffolding in the form of conceptual understanding of prerequisite materials. While students at level 0 need scaffolding to minimize the prototype phenomenon.

Abstract: This research aims to describe the mathematical representation ability of students with reflective cognitive style in solving geometric problems. The subjects of this study were two students whose reflective cognitive style were selected based on the results of the MFFT test. The research method used was descriptive research with a qualitative approach. The ability of mathematical representation was described based on three standards of mathematical representation ability, namely; (1) creating and using representations to organize, record, and communicate mathematical ideas, (2) choosing, using and translating between representations to solve problems, (3) using representations to create models and interpret mathematical, physical, and social phenomena. The results showed that subjects with reflective cognitive style can use mathematical representation capabilities well from various types of representations, namely visual images, verbal written texts, and mathematical expressions.Key Words: mathematical representation ability, reflective cognitive style, geometric problemAbstrak: Riset ini bertujuan untuk mendeskripsikan kemampuan representasi matematis siswa bergaya kognitif reflektif dalam menyelesaikan masalah bangun datar.

Abstract: The purpose of this research is to describe student errors that experience split attention in solving SPLDV problems. The subject of this study were two eighth grade students in SMP Muhammadiyah 2 Malang who experienced split attention. The instrument used in this research was a mathematical problem consisting of one SPLDV problem. The results of this research show that students who experienced split attention made factual errors and procedural errors in solving SPLDV problems. Factual errors made by students is that they cannot define the x and y variables they have made. Procedural errors is not being able to determine the resolution steps for the SPLDV problem. In addition, students also cannot use the addition operation correctly. The most common error is procedure error.Abstrak: Tujuan penelitian ini adalah mendeskripsikan kesalahan siswa yang mengalami split attention dalam menyelesaikan masalah SPLDV.
