Abstract

The background of this study is the school of the new students of mathematics education courses came from grade high, medium and low. Here the writer wants to see how much influence of the school level on new students’ critical thinking skills and creative mathematical. The purpose of this study was to examine differences in new students’ mathematical disposition, critical & creative thinking ability through the mathematical problem posing approach based on school level (high, medium, low). The method used in this research is the experimental method, with only posttest design. The population of this study is all the students of mathematics education department in Cimahi; while the sample is selected randomly from one college. Then from this chosen college is taken two samples from random class. The instrument of essay test is used to measure students’ critical and mathematical creative thinking ability; while non-test instrument is questionnaire of attitude scale. The results show that: 1) based on the school level (high, medium, and low); there is difference in students’ mathematical critical thinking ability through problem posing approach. 2) based on the school level (high, medium, and low); there is difference in the students’ mathematical critical thinking ability through problem posing approach. 3) based on the school level (high, medium, and low); there is difference in students’ mathematical disposition.

Abstract

Thinking creative is a thinking process which to produce kinds of idea possibility and the way widely and many to completed a problem, when applied thinking creative, will produce many useful ideas to find the resolver. Creative connects with finding something, about the thing that produces something new with using something that has been there. Research methods will use is descriptive qualitative. As for the sample in this research are seventh grade with high ability, medium and low in Kabupaten Bandung Barat. For the instrument test thinking, the creative ability will deliver to students are five question and following with interview in each student. Then, the results obtained was the level of their thinking creative ability according to their writing test and results of the interview with the low-level students. Next, this research is parts of my research paper will be careful.

Abstract

The purpose of this research is to develop local instruction theory on triangular and quadrilateral material and examine the improvement of mathematical representation ability by using local instruction theory. The method used in this research is design research method which includes three stages, namely: preliminary design, design experiment and retrospective analysis. The instruments in this study were in the form of tests and non-tests, where the tests used were aimed to determine the improvement of students' mathematical representation ability while non-tests such as interviews and observations were used to develop the local instruction theory. Subjects in this study were 40 junior high school students. The final result of this research is the development of local instruction theory teaching materials that can be used by the teacher to be used as a guide in teaching and the ability of students' mathematical representation in triangular and quadrilateral material is sufficiently increased

Abstract

Critical thinking ability is a process to leads to withdrawal conclusion about what do you believed and action will do. The importance of critical thinking ability on education and that is the main purpose of instructional, there are four importance component  for build that ability that is (a) explain and clarify; (b) asking the correct question to clarify or challenge; (c) consider the source of credibility; (d) problem solving and illustrates the conclusion. Method of the research will use is qualitative descriptive. As for the sample in this research is ninth of grade students on Cimahi city from high ability, medium and low. For the instrument test of critical thinking ability will deliver to students are five questions and following with interview for each student. Then, the results obtained was the level of critical thinking ability mathematics students in Cimahi city. Based on the writing test and the results of the interview with the low-level students.

Abstract

This study aims to analyze connection self-efficacy toward the ability of critical thinking on the material of circe of junior high school students. This research method using the qualitative descriptive method. This research is conducted in SMP Negeri 9 Cimahi in Grade IX of the academic year 2017-2018. The population of this study is the students of class IX SMP Negeri 9 and the subject of the research is all the students of class IX-A that consist of 34 students. To obtain the research data used the instrument in the form of test description and questionnaire self-efficacy. The results of the research concluded: (1) the level of students' mathematical critical thinking ability in the problem solution is still low; (2) students' difficulties, in general, have not understood the problem and the preconception is still low; (3) students have not embedded the sense of learning independently; (4)there are connection which is significant between self-efficacy toward mathematics critical thinking.
