The aims of this study are to determine the improvement of critical thinking skills mathematical and metacognition of students who are taught with problem solving approach and the correlation between mathematical critical thinking and metacognition of students. This research is an experimental research with pretest-posttest control group design. The sample this research is the students of class VIII_2 and VIII_3 in SMP Negeri 1 Banda Aceh. Collecting data technique are test and nontest. Data were analyzed using t-test and correlation test. The result of the research shows 1) the critical thinking ability of the students who get the learning through problem solving approach is better than the students who get the conventional learning, 2) Metacognition of students who get the learning by using problem solving approach is better than the students who get the conventional learning, 3) a positive and significant relationship between students' metacognition and critical thinking skills.

Learning Guide

<p><em>The demands of the 2013 curriculum ideally are that learning is able to develop 4C skills, one of which is critical thinking and problem-solving skills (Critical-Thinking and Problem-Solving Skills), namely being able to think critically, laterally, and systematically, especially in the context of problem solving. In fact, students' critical thinking skills have not been maximally developed, especially in elementary schools. The learning process in elementary schools currently requires problem-based learning that requires students to actively carry out investigations in solving problems and the teacher acting as a facilitator or learning guide will be able to shape the ability of students to think critically. The purpose of this research is to describe the concept of Problem Based Learning (PBL), the concept of critical thinking ability, and the relationship between Problem Based Learning (PBL) and critical thinking ability. The results of the Problem Based Learning (PBL) model improve critical thinking ability.</em></p>

The purpose of this study was to determine the mathematical critical thinking ability of students who were taught using the Auditory Intellectually Repetition learning model was better than the mathematical critical thinking skills of students who were taught through a scientific learning approach. This study uses a quantitative approach and the type of research used is quasi-experimental research. The population in this study were 11th grade students of SMA Negeri 5 Simeulue Barat, the samples in this study were two classes selected using a nonprobability sampling technique of purposive sampling type, namely class 11 IPA-1 as an experimental class using the Auditory Intellectually Repetition model and class 11 IPA-2 as a control class using a scientific approach. The data processing technique uses SPSS version 25 with the results of the study showing that: the value of Sig (p-value) > 0.05), it is accepted that it is 0.629 in the experimental class and 0.273 in the control class so that the data has a normal distribution. The t-test analysis of students' mathematical critical thinking skills was obtained 0.001 < 0.05, then Ho was rejected and Ha was accepted. This means that the mathematical critical thinking ability of students who are taught with the Auditory Intellectually Repetition learning model is better than the mathematical critical thinking skills of students who are taught with a scientific learning approach.

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.

Problem solving attitude is one of the most important aspect of the students in handling problems that they encountered. Meanwhile, critical thinking ability is also an important skill of the students in dealing and analyzing the problems and to it appropriately. The study used descriptive correlation design to determine the relationship between problem solving attitude and critical thinking ability of the students. The study has 240 respondents from the different strands (ABM, HUMSS, GAS, TVL and STEM) in certain senior high school: Mandaue City, Cebu, Philippines. The tool used in this study in getting the information and data collection is rating scale questionnaire. All the data are analyzed using weighted mean and chi-square to show the result. The result shows that the problem solving attitude is significantly associated to the critical thinking ability of the students. Students who have high level of problem solving attitude will become successful ones someday, because they don’t get affected in their problems instead, they solved it right away with their critical thinking. Students' critical thinking ability is very useful in solving and analyzing their problems.

Improving the critical thinking ability of students is a learning outcome of many undergraduate and graduate courses.  While case-based courses encourage higher order critical thinking, students still often become rote in the application of concepts and theories to problem-solving situations.  This paper presents an example of a graduate marketing MBA course that was revised by integrating the creative problem solving process with the traditional case analysis process in order to enhance student critical thinking and problem solving skills.
