Abstract

AbstractThis research aims to describe how metacognition skills are assessed from student learning outcomes in class XII quadratic equation material at SMA St. Fransiskus Asisi Pontianak. The research method is descriptive with the survey. The subjects of this study were six students of class XII Natural Sciences which consisted of two students with high learning outcomes, two students with moderate learning outcomes, and two students with low learning outcomes. The results of this study indicate that metacognition skills for learning outcomes are high, almost all indicators are fulfilled in every planning, monitoring, and evaluation. While metacognition skills for learning outcomes are moderate, only planning and monitoring indicators are met, evaluation is still lacking. There for metacognition skills for learning outcomes are low, only planning indicators are met, monitoring and evaluating is still lacking.Keyword : Metacognition Skill, Learning outcomes, Quadratic Equation

Abstract

AbstractThe facts show that students' understanding of the concept of absolute value is still in low classified. The lack of understanding of student concepts is influenced by several factors, one of which is lack of student confidence in working on problems. self confidence is one part of student learning independence. Therefore this study aims to describe the understanding of the concept of the absolute value equation in terms of student learning independence. The research method used is descriptive qualitative in the form of case studies. Subjects were thirty-eight students in SMA Negeri 2 Pontianak. The results of this study indicate that students' understanding of concepts is balanced with learning independence. students who have a high level of learning independence overall the results of the concept understanding test are also high. students who have a level of independence of learning while overall the results of the test understanding of the concept are also being. students who have low levels of learning independence overall the results of the concept understanding test are also low. The conclusion from study's result showed that level the high student's independence learning, the level student's concept understanding was high also.Keywords: Absolute Value Equations, Concept Understanding, Learning                  Independence

Abstract

AbstractThis research generally aims to clarify and solve learning obstacle in the problem solving of System of Linear Equations In Three Variables in the tenth grade of MA Al-Mustaqim Kubu Raya. To minimize the learning obstacles, the didactic design was arranged. The form of this research was didactic design research with a qualitative approach. This study was conducted by giving the pre-test questions of problem solving to 27 students, then selecting four students to be the research subjects randomly. After analyzing the results of the pre-test, students experienced learning obstacles in understanding the problem, arranged a solution plan, implementing a settlement plan, and recheck the results obtained. After that, the researcher arranged the didactic design in the form of learning scenarios and the student worksheets. The didactic design that has been prepared is tested on research subjects. After that, the researcher gave the post-test questions. The post-test results showed that the obstacles that experienced by the four research subject reduced  Keywords: Didactical Design, Learning obstacles, Problem Solving

Abstract

AbstractThe aim of this research is to describe the form of mathematical fallacy and its causing factors. The research method used is descriptive method in the form of case study research. The subjects of this research are eight senior high students, four students from SMAN 1, two students from SMA Santo Paulus and two students from SMAN 3, who participated in National Science Olympiad 2019 in Pontianak. Mathematical fallacy in this research consists of three forms. They are division by zero, mistaken of taking squares and exponent fallacy. Mathematical fallacy in the form of division by zero was done by 5 students, mistaken of taking squares was done by 6 students, while exponent fallacy was done by 8 students. It was concluded that there were five factors leading to mathematical fallacy. Those are (1) Students were trying to skip several mathematical procedures who claimed as not substantive; (2) Students lacked of understanding in using the argumentation scheme in the form of procedural/steps to solve the problems; (3) Students took  the conclusion hastily without depth analysis; (4) Teachers tend to skip certain facts, concepts, principles and mathematical procedures; and (5) Some text books students used contain things which may lead to mathematical fallacy.Keywords: Mathematical Fallacy, Olympiad, Procedure

Abstract

Pemahaman konseptual terbagi pada lima indikator yaitu mengidentifikasi fakta-fakta yang berkaitan; mengenali contoh dan noncontoh; menafsirkan tanda-tanda, simbol dan istilah; memanipulasi ide-ide terkait; menyempurnakan hubungan konsep dan prinsip. Pemahaman konseptual siswa masih rendah, hal ini dapat dilihat dari pengetahuan prosedural mereka. Pengetahuan procedural siswa masih kurang, hal ini disebabkan kurang terbiasanya mengembangkan berbagai cara yang kemungkinan dalam memecahkan suatu permasalahan matematika. Mereka hanya meniru pola yang diajarkan guru tanpa memahami mengapa menggunakan langkah-langkah yang demikian.Kata kunci: pemahaman, pengetahuan, konseptual, prosedural, kemampuan

Abstract

AbstractThe background in this research is the student’s adaptive reasoning ability that is still relatively low. Adaptive reasoning ability are influenced by some factors,  one of them is student’s cognitive style. Therefore, adaptive reasoning ability should be analyzed based on student’s cognitive style. This research aims to describe the student’suu adaptive reasoning ability based on cognitive style in quadrilateral at SMP Negeri 8 Pontianak. The research method use descriptive method with case study. The subject in this research are four students grade VIII D consist of two reflective cognitive style students and two impulsive cognitive style students. The result of data analysis showed that the adaptive reasoning ability are different depending on their cognitive style.  One of students who has reflective cognitive style can  fulfill five indicator of adaptive reasoning ability and one of other students who has reflective cognitive style can  fulfill four indicator of adaptive reasoning ability. One of students who has impulsive cognitive style can  fulfill four indicator of adaptive reasoning ability and one of other students who has impulsive cognitive style can  fulfill two indicator of adaptive reasoning ability.  Keywords: Adaptive Reasoning Ability, Cognitive Style, Quadrilateral

Abstract

Abstract  The background of this research was the lack of junior high school students’ spatial reasoning and quantitative reasoning  in Pythagoras theorem. This research used Didactical Design Research (DDR) method which started by a preliminary study to 18 students of grade IX A Bumi Khatulistiwa  Junior High School.  The preliminary study was aimed to explore students’ learning obstacles to develep didactical design. The developed didactical design was implemented to 20 students of grade VIII A of Bumi Khatulistiwa  Junior High School. After this implementation the developed didactical design was revised. The results of this research were the learning tools used by previous teacher have  explored spatial reasoning and quantitative reasoning, the developed didactical design had minimized students’ epistemological obstacle.    Keywords: Didactical Design, Spatial Reasoning, Quantitative Reasoning, Epistemogical Obstacle
