Deskripsi Proses Kognitif Siswa SMP dalam Menyelesaikan Masalah Matematika Berdasarkan Modes Of Representation Teori Bruner
Full text linkThere are three steps of cognitive processes, that is: 1) acquire new information, 2) transform information; and 3) test the relevance and accuracy of knowledge or evaluation. This study aims to describe the students the cognitive process of junior high school to solve mathematical problems based on Bruner's three modes of representation. The research is qualitative descriptive. The subjects were three students of junior high school; each of them is with high, medium, and low abilities. The results showed that the cognitive processes of high and medium abilities were able to acquire information and transform it to solve the problems in the enactive, iconic, and symbolic representation. For the testing relevance and accuracy, high-ability subject only works in the enactive representation. Middle-ability does in the enactive and symbolic representation. The low-ability subject was able to do all three cognitive processes on questions the enactive representation, but other questions in the iconic and symbolic representation cannot be solved

Kemampuan Metakognitif dan Komunikasi Matematis dalam Pemecahan Masalah Matematika
Full text linkThis descriptive qualitative study aims to describe the metacognitive and communicative abilities of the third-semester students of Mathematics Education of UIN Sunan Ampel Surabaya. Forty students were given a test consists of 2 essay problems of number theory. Three of the answer sheets that each one representing students with high, medium, and low scores were analyzed. Findings show that the students' ability in both aspect are unsatisfactory regardless of their different scores. They are don't show their understanding of the concepts and principles of number theories, some of them still use mathematical terms and notes, and the majority still have the wrong calculation because they not use the complete and correct algorithm. The students' ability in mathematical communication is poor because they can't write the correct mathematical symbols and can't put the mathematical ideas in an acceptable, logical order. They have written the answers that seem to the right answers, but the arrangement of the answers is irrational and jumping, resulting in the answers in low comprehensibility
Restrukturisasi Berpikir Siswa Melalui Pemunculan Skema dalam Menyelesaikan Soal Ujian Nasional Mata Pelajaran Matematika
Full text linkDefragmentation of student’s thinking structures through scheme appearance to fix pseudo thinking student’s in solving problems HOTS test type for mathematics in the National Exam 2018. Pseudo Thinking happened because students did not reflect before answering, so students give the wrong answer. Pseudo thinking divided into false-pseudo thinking and true-pseudo-thinking. Hence, in this research to describe student’s structural thinking errors and the process of defragmentation of student’s thinking structures through scheme appearance to fix student’s pseudo thinking in solving problems of HOTS test type for mathematics in the National Exam 2018. This research is qualitative research with descriptive type. Researchers used three subjects to describe the defragmentation process of scheme appearance. The result of this research, all subjects experienced false-pseudo thinking and true-pseudo thinking. From the research, subjects can reveals that the process of scheme appearance that has been previously. So subjects can solve problems
