The Potency Of Metacognitive Learning To Foster Mathematical Logical Thinking

The ability of thinking logically needs to be developed due to the fact that it is an essential basic skill. Logical thinking affects that giving reason must be true, and that a sequence of assumptions is based on the high truth value. Mathematics is a subject that functions to train students to think logically. The understanding of logic will help students to arrange the proof that support through process to finally arrive at a conclusion. Currently, metacognition is viewed as an essential element of learning. It refers to someone knowledge of processes and the result itself or of that connected to the process. Metacognition is needed when student solves the task that needs argumentation and logical understanding. In order to help student to skillful think logically, mathematics learning must be designed as such so that the condition will raise the skill of metacognitive acts. Key words: metacognitive learning, mathematical logical thinkin

Hidden Curriculum in Promoting Self-Regulated Learners for Teachers

Teachers and students in general are surrounded by many things and information when they are interacting with people on campus or off campus. Therefore they might absorb many lessons that are not included formally in the formal course of study on campus. Those aspects that they absorb in the long run somehow may contribute to their performance in terms of their achievements, skills or on their character. What they absorbed might be positive or negative, depends on the environment that the students as well as the teachers have on campus. The situation might be so diverse in terms of culture, languages, races, social status etc. It means that the student as well as the teachers must realize the importance of becoming self regulated learners, that they must learn how and what to learn or what to teach related to the issue of hidden curriculum. Very often the students as well as the teachers did not realize that when they interact with one another there must be certain message that they convey to one another that they must take the advantage of being interactive is a very important momentum to be used appropriately. It is important that the interaction should be conducted intentionally in order for them to learn from the hidden curriculum. This means that they need to be sensitive in noticing a good momentum to learn different aspects so as to act to change what could be changed in the future

KARAKTERISTIK KEMAMPUAN PEMECAHAN MASALAH SISWA KELAS VIII DI KABUPATEN BANDUNG BARAT

This study aims to determine the characteristics of the problem solving abilities of class VIII students in a junior high school in West Bandung Regency. In this study using a qualitative descriptive research method. The data collection technique in this study was in the form of test questions. The test results were analyzed by the emergence of problem solving abilities based on the Polya procedure for each question. The test instrument used is a description test. Based on data analysis of the study found that the stages of solving problems obtained 87% results, and at the other 3 stages namely understanding the problem obtained 55% results, planning problem solving obtained 30% results and checking again obtained 20 results %. Thus, there are still many students who do not write down what is known, are asked, and do not describe these elements, are not systematic in the problem solving process, do not understand the problem, are wrong in calculating answers, and do not write conclusions, and the main factor is not students are used to solving problems in the form of stories with complex daily life contexts, so there are still many errors in problem solving systematics found in junior high school students

The Effect Of Self Confidence On The Ability Of Understanding Mathematical Concepts Of Junior High School Students On The Triangle And Quarter Matter

This research aims to analyze and study in depth about the self-confidence-influenced skills of matematiS from middle school students. The methods in this study use correlational methods with quantitative approaches. The population in this study was junior high school students in west Bandung regency and the sample of 30 people was determined by purposive sampling technique at one of the junior high schools in West Bandung Regency. Instruments in this ability in the form of comprehension ability tests as many as 5 points of questions and self-confidence scale students as many as 24 statement scales. The results of this study concluded that there is a positive influence between self-confidence and the mathematical understanding ability of middle school students. This shows that the higher the student's confidence, the higher the student's mathematical comprehension ability. Factors that affect high self-confidence include: (1) students with a high confidence attitude do not hesitate in making decisions in solving problems (2) students can have many ideas in working on the problem at hand. Meanwhile, students with less confidence will tend to have difficulty in answering potluck questions, students only memorize not yet to understand the understanding of the concept so that the student does not dare to make decisions when solving existing problems.Kata kunci: self confidence, mathematical understanding

Concept of Triangle: Examples of Mathematical Abstraction in Two Different Contexts

Geometry has abstract notions to be learnt so that all those notions cannot be just transferred into students’ mind like a bunch of information that should be memorized. Students need to construct those concepts during their learning process. This process of knowledge construction can be considered as an abstraction process. This study aimed to qualitatively compare abstraction process of students who learned the topic of triangle in conventional method and in van Hiele model of teaching aided by Geometers’ sketchpad. Subjects of this study were junior high school students in grade 7. This is a qualitative study with grounded theory design. Data were collected through classroom observation, test, and task-based interview. Results of the study show that theoretical abstraction processes tend to dominate classrom with conventional method of teaching while classroom with van Hiele model of teaching aided by Geometers’ sketchpad accommodated empirical abstraction process of the students
