IMPROVING THE ABILITY OF MATHEMATIC PROBLEM SOLVING, MATHEMATIC CONNECTION AND SELF REGULATED LEARNING WITH JUNIOR HIGH SCHOOL STUDENTS THROUGH METAKOGNITIVE APPROACH

This study is a quasi experiment, aiming to describe the level of achievement of problem solving abilities, mathematical connections of students and the independence of junior high school students through metacognitive approach. The sample was chosen randomly from the class of all students of class IX in one of SMP Negeri in Karawang regency. The two class samples were chosen as control and experiment classes. Each of us uses a set of problem solving and mathematical connection tests and a set of learning independence scales. The study found that the attainment and improvement of problem solving ability and mathematical connection ability of students using metacognitive approach is better than the students whose learning is using normal learning in terms of the students' initial ability level. While different from the independence of students who learn learning using metacognitive approach is not better than students who use regular learning in terms of initial ability level of students. However, there is no interaction between the metacognitive approach and the student's initial ability level in generating problem solving skills and mathematical connections as well as learning independence which means that increased problem solving abilities and mathematical connections are largely influenced by the metacognitive approach

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

Analisis kemampuan pemahaman matematis siswa kelas VIII SMPN 3 ngamprah pada materi relasi dan fungsi

The aim of this study was to describe how well students understood relational and functional mathematics. By examining the typical student responses to prepared instrument questions, descriptive qualitative research methodology is applied. The study's instrument was a written test of math comprehension that had six questions and three indicators of math understanding: classifying objects with specific properties in accordance with the concept, presenting the concept in various mathematical representations, and using a problem-solving strategy or algorithm. 30 pupils from SMPN 3 Ngamprah in grade VIII served as the study's subjects. According to the analysis's findings, class VIII pupils at SMPN 3 Ngamprah's mathematics knowledge abilities were rated as low, and students received a sufficient

Pengembangan LKPD problem based learning berbantuan liveworksheet pada materi aritmatika sosial

The purpose of this research is to analyze the feasibility and validity of problem-based learning worksheets assisted by liveworksheets. This development research was carried out using the 4D method which includes the Define, Design, and Development stages. In the analysis stage of the feasibility and validity test data, questionnaires and documentation were collected. The feasibility of teaching materials was analyzed based on the results of expert validation and the practicality of teaching materials based on the results of students' answers. The results of this study indicate that the tested LKPD is feasible and valid as learning material for students. Expert validation results produce an average score of 89.8% with a very valid category, it can be said that it is feasible to use in the field. The results of the student response questionnaire analysis showed that LKPD was considered practical by students with a percentage of 75% in the limited trial while 82% in the broad trial with the very practical category. This can show that the problem-based learning worksheet on social arithmetic material assisted by the liveworksheet is very good for use during the mathematics learning process

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

Effectiveness of Progressive Learning Approach toward Enhancement of Students’ Competency on Mathematics Journal Writing and Mathematical Proof

This is quasi-experimental research of two different groups of 41 and 46 mathematics students. This research was conducted at Haluoleo University of Kendari South-East Sulawesi Indonesia. Progressive learning approach was applied to group of 41 students as an experimental group and conventional learning approach was applied to the other group of 46 students as conventional group. The students were also categorized by their grade point average (GPA) into higher, medium, and lower levels. Mathematical journal writing and mathematics proof competencies were measured by pre-test and post-test on both areas. Scores of these tests were analised with Anacova test, two-way Anova, t-test, and Mann-Whitney U test. In this reaseach students were expected to have mathematics journal writing and mathematical proof competencies. The results of the research are (1) students’ mathematics journal writing competency and students’ increment at mathematics journal writing competency of progressive learning approach is better than that of conventional one; (2) students’ mathematical proof competency and students’ increment at mathematical proof competency of progressive learning approach is better than that of conventional one, but students’ increment of mathematical proof competency at lower level of GPA is not significantly different. Keywords: progressive learning approach, mathematics journal writing competency, mathematical proof competenc
