Abstract
This research is a pre-post-test experiment that aims to examine the role of the problem-solving approach (PSA) and students’ cognitive intelligence on mathematical creative thinking abilities (MCTA) and mathematical habits of mind (MHoM). This study involved 50 8th grade students. The instruments used were TOLT test, MCTA test, and MHoM scale. This research found that students at the age of 13-14 years are at the stage of formal, transition, and concrete thinking. Whereas MCTA students who receive learning with PSA achieve better grades than students taught by the scientific approach (SA). The MCTA level of students who receive PSA is good and sufficient for students who receive SA. Both groups of students are still aware of some difficulties in completing MCTA tasks, such as solving problems improperly, in more than one way, and or in different ways. The MHoM results of the two students were not different, they were at a good level. Based on the cognitive thinking stage, it was found that there were significant differences in the improvement of MCTA between the two classes, there was a certain stage of thinking in the MCTA of the two classes, and there was no interaction. While for MHoM there is no difference in terms of approaches and stages of thinking, and there is no interaction. In Other findings, there is no relationship between MCTA and MHoM.

Abstract
To date, in the literature, hundreds of studies have been found on mathematics learning that is supported by the Contextual Teaching and Learning (CTL) Model. Several studies with conflicting results are found in the literature. This meta-analysis study was carried out to combine and interpret the findings of this study. Related databases are sought for studies that qualify for examining the effects of CTL compared to conventional learning on students’ mathematical understanding abilities. Random-effect models with 95% confidence intervals (CIs) were estimated. 21 effect sizes were analyzed from 21 primary studies that met the inclusion criteria and were published in ERIC documents, journal articles, proceedings, and repository documents from 2010 to 2020, and with a total of 1349 students involved. The Comprehensive Meta-Analysis (CMA) program is used to assist analysis. Based on the results of the analysis found the overall effect size (ES) is 0.868 with a standard error of 0.155 based on a random-effects model. The size of the effect represents that the average student exposed to CTL exceeds the ability of mathematical understanding by 76% of students in conventional classes who are initially equivalent. This result can also be interpreted that, students shift from the 50th percentile to the 79th percentile in mathematical understanding abilities when CTL is applied. The results of the analysis of the mediator variables were found that all variables except the year of study and education level were related to ES. The strongest relationship was found for sample size variables and publication sources. The analysis shows that CTL is more effective if it is applied in the condition of a sample size of 1-30 students. It was found that there were sources of publications which tended to publish only significant studies, although they did not indicate publication bias. These facts are considered by mathematics education practitioners for CTL implementation in the future.

AbstractThe background of this study is in fact that students’ abstraction process still low in geometry. Straight-line equations are a prerequisite in understanding geometry material further. Therefore, the objective of this study is to measure the process of student abstraction in straight line equations. The population in this study are Eight Graders from one of the junior high schools in Cimahi City, with the selection of research subjects, namely schools in the medium cluster category in Cimahi City. and the samples in this study are 3 students that categorized on high, medium and low abilities. This research is a descriptive qualitative study. The instrument of the research is a test that is analysed to see and measure the student’s abstraction process which appears in straight line equations. The results of the analysis and observations show that the abstraction process from 3 students who categorized based on high, medium and low ability, shows different ability on abstraction process on the criteria of verbal reasoning, numerical ability, and abstract reasoning. Students with high ability category have high variable reasoning ability, high numerical ability and high abstract reasoning as well. While students with medium abilities have high variable reasoning abilities, moderate numerical abilities and medium abstract reasoning. For students with low ability categories have low variable reasoning ability, moderate numerical ability and low abstract reasoning. So this process of abstraction can be seen from students with high ability categories. As for students of medium and low ability, need more guidance so that their abstraction process can improve.

Published: October 2020

Abstract
Changes to the curriculum in Indonesia have also caused changes in the learning process. Students are required to play an active role in classroom learning, while teachers only act as facilitators. So that in this curriculum, students are expected to have self-regulated learning. But also, another aspect that must still be had by students is a good understanding of concepts, especially in a material that is considered difficult like mathematics. One alternative way that can be done to achieve both aspects is the use of instructional media, such as interactive multimedia. One interactive multimedia that can be used is the Macromedia Flash Professional 8 application. This study aims to compare two groups with different treatments on trigonometry material. This study uses a quasi-experimental method with the non-equivalent control group design. This study was divided into two groups; the first group was given learning using flash media as an experimental group and the second group as a control group using ordinary learning. The sample in this study was taken from two classes of thirteen classes with purposive sampling, namely class X RPL 2 and X AKKUL 1 in SMK Negeri 1 Cianjur. Data were analyzed using the Mann Whitney Test and the Independent Sample t/t′-test. The results showed that the achievements and increased ability to understand mathematical concepts from the experimental group were significantly better than the control group. Based on N-gain criteria, the increased is including the medium category. At the same time, the self-regulated learning of the experimental group is the same as the self-regulated learning of the control group.
