Abstract: Mathematics is a science that is universal and able to integrate with other subjects. One of the goals of mathematics learning based on Kurikulum Tingkat Satuan Pendidikan is to understand, explain and apply mathematical concepts in the context of problem solving. But in the field, the students tend to difficulties in resolving problems related to problem solving in mathematics. This is due to the low ability students in mathematical problem solving in students' learning because not used to thinking creatively. It required a real effort to improve students' problem-solving abilities in mathematics. One of the measures taken namely through mathematics model Multy Discourse Representation (DMR). Learning with models DMR is one alternative that can be used because it exposes students to work in groups, in order to issue a power of representation held by the students.Keyword: Problem solving ability, DMR Model, Mathematic learning. Abstrak: Matematika merupakan suatu ilmu yang sifatnya universal dan mampu berintegrasi dengan mata pelajaran lain. Salah satu tujuan pembelajaran matematika berdasarkan kurikulum tingkat satuan pendidikan adalah memahami, menjelaskan dan mengaplikasikan konsep matematika dalam konteks pemecahan masalah. Namun dalam pelaksanaan di lapangan, siswa cenderung kesulitan dalam menyelesaikan persoalan terkait pemecahan masalah dalam pembelajaran matematika. Hal ini disebabkan rendahnya kemampuan siswa dalam pemecahan masalah matematis karena dalam pembelajaran siswa tidak terbiasa berpikir secara kreatif. Untuk itu diperlukan upaya nyata dalam meningkatkan kemampuan pemecahan masalah siswa dalam pembelajaran matematika. Salah satu upaya yang diambil yakni melalui pembelajaran matematika dengan model Diskursus Multy Representation (DMR). Pembelajaran dengan model DMR merupakan salah satu alternatif yang dapat digunakan karena menghadapkan siswa kepada bekerja secara berkelompok, supaya dapat mengeluarkan daya representasi yang dimiliki oleh diri siswa.Kata kunci: Kemampuan pemecahan masalah, Model DMR, Pembelajaran matematika

In this paper, we explore the challenges experienced by a group of Primary 5 to 6 (age 12–14) students as they engaged in a series of problem-solving tasks through block-based programming. The challenges were analysed according to a taxonomy focusing on the presence of computational thinking (CT) elements in mathematics contexts: preparing problems, programming, create computational abstractions, as well as troubleshooting and debugging. Our results suggested that the challenges experienced by students were compounded by both having to learn the CT-based environment as well as to apply mathematical concepts and problem solving in that environment. Possible explanations for the observed challenges stemming from differences between CT and mathematical thinking are discussed in detail, along with suggestions towards improving the effectiveness of integrating CT into mathematics learning. This study provides evidence-based directions towards enriching mathematics education with computation.

Teacher's Beliefs

This is a case study investigating a primary teacher’s beliefs, knowledge, and teaching practice in mathematical problem solving. Data was collected through interview of one primary teacher regarding his beliefs on the nature of mathematics, mathematics teaching, and mathematics learning as well as knowledge about content and pedagogy of problem solving. His teaching practice was also observed which focused on the way he helped his students solve several different mathematics problems in class based on Polya’s problemsolving process: understand the problem, devising a plan, carrying out the plan, and looking back. Findings of this study point out that while the teacher’s beliefs, which are closely related to his problem solving view, are consistent with his knowledge of problem solving, there is a gap between such beliefs and knowledge around his teaching practice. The gap appeared primarily around the directive teaching which corresponds to instrumental view he held in most of Polya’s process during his teaching practice, which is not consistent with beliefs and knowledge he professed during the interview. Some possible causes related to several associate factors such as immediate classroom situation and teaching practice experience are discussed to explain such inconsistency. The results of this study are encouraging, however, further studies still need to be conducted.

Problem solving must be developed and internalized in mathematics<br />learning, so students have problem solving skills that students can<br />transfer to their daily lives when facing problems or difficulties.<br />There is a mental attitude that affects a person's success to become a<br />successful problem solver, namely adversity quotient. This mental<br />attitude affects the mindset and emotions so it is not easy to give up<br />in solving problems. This study aims to measure the relationship<br />between adversity quotient and problem solving abilities of junior<br />high school students in mathematics learning. This research is a<br />correlation study. The population was students of SMPN 1 Padang<br />Panjang 2014/2015 academic year, while 32 samples were selected<br />by purposive sampling. The data was collected using an adversity<br />quotient scale and a mathematical problem solving ability test. Data<br />were analyzed by regression correlation techniques. The results of<br />data analysis showed a correlation coefficient between adversity<br />quotient variables with mathematical problem solving abilities of r =<br />0.756&gt; rtable (0.297), meaning that there was a significant positive<br />relationship between adversity quotient and mathematical problem<br />solving abilities. The coefficient of determination obtained is r2 =<br />0.572 indicating that adversity quotient has an effect of 57.2% on<br />mathematical problem solving abilities of junior high school<br />students, while 42.8% is influenced by other factors
