Abstract

The Mathematics students who perform truth-seeking process upon solving mathematical problems were unique. Therefore, the study deems it necessary to know students’ mental structure and mechanism so that they can make the right decision by performing truth-seeking. However, no research has delved into the mental structures and mechanisms of Mathematics students, who tend to grapple with truth-seeking processes extensively. This study was explorative qualitative because the aims to describe the types of mental structure and mechanism of Mathematics students upon the truth-seeking process in solving mathematical problems. The research subjects are four Mathematics students at the University of Jember who perform truth-seeking and can communicate fluently when performing think-aloud. Their responses in the answer sheets drove the determination of research subjects' tendency in truth-seeking. Afterward, the results of think-aloud and task-based interview were put under analysis, so as to determine the types of mental structure and mechanism. The research findings have indicated that (1) all mental structures have been constructed by all research subjects and (2) two types of mental mechanism are evident among the subjects, including the process of interiorization coupled with coordination and another process encompassing interiorization, coordination, and reversal.

Abstract

The determine of this study is explain the thinking process of high and low performing students in solving mathematical problems, so classified in qualitative research. The data collection is done by the provision of initial tests, giving the final test, and interviews with the study subjects after solving mathematical problems. The results showed that high-ability student fulfills the know, want, and introduce at the stage of entry. In the attack phase fulfills the try, maybe, and why. At this stage of the reviews meet the check and reflect aspects. Low-ability students meet aspects know and want the entry stage. In the attack phase fulfills the try and do a review on the stage of mathematical problem solving.

Abstract

This study is a qualitative and placed in UPT SMPLBN Kota Pasuruan. Subjects in this study is a blind student of class IX of the school year 2015/2016. The results showed that the thinking of blind students starts from the stimulus, stimulus in the form of problem enter into the sensory registers of blind students through the sense of tactile and auditory, and into short-term memory after previously through a phase of selective attention and perception, in the short-term memory old information in the form of concepts that are needed in solving the problem called from long-term memory (retrieval), when information leaves short-term memory, there are two possibilities occur that information will lead to long-term memory (encoding) and or will be forwarded towards the environment in the form of responses/answers to students.

Abstract

The purpose of this research is to describe the reasoning of reflective students' analogies in solving trigonometric problems. Problem trigonometry presented a problem that contains the problem analogies. This study used a qualitative descriptive approach with an analogy reasoning test instrument. Data analysis is a description of words. The process of data analysis starts from reducing data, data exposure, verification and affirmation of conclusions. The subjects took one class X MIA 1 containing 30 students. The location of the research was conducted at MAN Mojosari Mojokerto. The cognitive style of students is measured using MFFT tests which can ultimately be categorized by students with reflective and impulsive cognitive styles. From the result of student's answer identification, it is found that the students are doing trigonometric questions with the sequence of components that exist on analogical reasoning according to Sternberg. However, there is an error in meganalogikan about trigonometry given due to lack of mastered concept.

Abstract

Mathematics is a science that is rich concept, where the concept of one another have relevance. In connection with the concept, there is a common mistake made by students are misconceptions. The misconception is that most fatal errors compared to other errors. Because he tends to defend himself when he was given awarning. So the study has the aim to describe misconception that occurs in radical numbers. Subjects in this study were junior high school students of class IX who have misconceptions on radical numbers based on the results of diagnostic tests misconception comes with a confidence level of students in working on the problem. The results showed that students have misconceptions on the concepts and properties that exist in the form of roots.

Abstract

The purpose of this study is to describe students writing mathematical communication of high-ability (ST), medium (SS), low (SR) in solving problem. The research data was obtained by analyzing the answer sheets of three subjects based on writing mathematical communication indicators. The result of this research are, (1) ST can write what is known and asked, construct Venn diagram and do the calculation correctly, (2) SS can write what is known and asked, construct Venn diagram and do the calculation of problem 2 correctly, but on problem 3 SS still make any mistake on constructing Venn diagram and doing the calculation, (3) SR can write what is known and asked, but SR has not made Venn diagram and done the calculation appropriately.

Abstract

This study aims to describe the defragmentation process of SMAN 4 Malang 12th grade impulsive students’ thinking structure on solving word problem. Two selected subjects do the initial test by think aloud method, interview process, and evaluation test. The results of this study shows that students’ errors on understanding the word problem and carrying out the plan steps can be fixed through disequlibration, conflict cognitive, and scaffolding intervention; students’ errors on devising a plan step can be fixed through disequlibration intervention; students’ errors on looking back step can be fixed through disequlibration and scaffolding intervention.
