Problem solving is an important skill that need to be developed in mathematics education. Sharpening problem solving skills enablestudents to improve their ability to analyze and train students to think creatively. However, in reality the students were less facilitated in sharpening the development of problem-solving abilities. Consequently, the problem solving ability of students has not been satisfactory. One of the efforts that could be done to overcome his problem is applaying metacognitive scaffolding approach in learning. Metacognitive scaffolding is an approach that emphasizes self-monitoring capability. Monitoring is the way a person monitors what students know and do not know. While scaffolding is a help given by the teacher to the students. When students feel able to work independently, teachers slowly reduce scaffolding. This study aimed to determine whether the approach of metacognitive scaffolding could improve problem-solving abilities. Thereserach applied quasi experimentresearch with Nonequivalent Control Group Design. This research took place in one of State Senior High School in Padang Pariaman District, West Sumatera. The results show that metacognitive scaffolding approach could improve mathematical problem solving ability.

Mathematical representation is one of the important abilities mastered by students, in an attempt to find a solution of a problem, both math problems, as well as daily problems. One way to increase this ability is through mind mapping strategy. Mind mapping strategy involves students actively in mapping information through effective note-taking techniques. The mind map process shows a picture of interconnectedness, and a clear relationship between concepts. In expressing an idea, students can recall information associated with the learned knowledge by projecting the idea into a map or graphic technique. In addition, mind mapping activities can enhance students creativity through freedom of imagination, so learning becomes more interesting. The main problem in this research is whether mind mapping strategy can increase students mathematical representation. This research is a quasi-experiment with nonequivalent control group designs. This research involves 63 tenth grade students in Muara Bungo, Jambi. The result of this research is a significant improvement to students mathematical representation through mind mapping strategy.

Improving students' mathematical competence such as problem-solving skills, mathematical communication, reasoning, and others can use the Problem Based Learning model. This study aims to analyze the impact of the Problem Based Learning model in improving the mathematical competence of students from primary school, junior high, and senior high school levels. The research method used is Systematic Literature Review (SLR). The sample comprises 17 research results on the PBL model in improving students' mathematical competence (concept understanding, problem-solving, and communication skills). The sample comes from indexed journals from the period 2012-2019. The key research question is how PBL influences students' mathematical competence based on the year of school, level of study, research location, and sample size. The SLR method can find an increase in the number of eight-year studies. The results showed that communication skills and understanding of mathematical concepts dominated research results in improving mathematical abilities through problem-based learning models. Most of the research was conducted at the junior high school level outside Java, with a sample size of 30 people or more. Based on the results of the review, the study’s conclusion proves the influence of the Problem Based Learning (PBL) model on students' mathematical competence.
