This research is an qualitative descriptive research which aim to know high or low the ability of mathematical creative thinking and mathematical critical thinking on system of two variable equations. The subject of this research were 30 students at 10th grade in one of the vocational high school in Galanggang Village. Data collection is done by giving 5 questions for each creative thinking ability and critical thinking ability to the students. Data obtained are then processed and analyzed later will concluded that mathematical creative thinking ability and mathematical critical thinking ability in one of the vocational high school in Galanggang Village is still low. This conclusion is based on results the average of the percentage obtained from the five indicators of creative thinking ability is 21.81% and from critical thinking ability is 43.44%.

The purposes of this study are to identify the level of communication skills and mathematical resilience of junior high school students and to find out their mistakes in finishing communication-based questions. The method used in this study is descriptive quantitative method. This study is conducted in an Islamic school namely MTs Al Basyariyah located in Bandung, Indonesia. Performing as the respondents of this study are 36 students of class IX-B. To collect the data, this study employs a communication-based question diagnostic test and a questionnaire on student resilience. The results of the study show that (1) most of the students find it difficult to do question number one whose indicator is written text; (2) students’ skill on doing communication-based questions is still low; and (3) there is not significant correlation between students’ communication skills and their resilience. To cope with these phenomena, it is recommended that teachers use learning strategies that are able to enhance students’ conceptual understanding so that their communication skills can be achieved.
本研究的目的在于了解初中生的沟通技巧和数学弹性水平，并找出初中生在完成沟通问题时所犯的错误。本研究采用描述性定量方法。这项研究是在印度尼西亚万隆的一所伊斯兰学校进行的，即MTs Al Basyariyah。本研究的被调查者为IX-B班的36名学生。为了收集数据，本研究采用基于沟通的问题诊断测试和学生心理弹性问卷。研究结果表明:(1)大多数学生对以书面文本为指标的问题一感到困难;(2)学生做沟通型问题的能力仍然较低;(3)学生沟通能力与心理韧性之间不存在显著相关。为了应对这些现象，建议教师使用能够增强学生概念理解的学习策略，从而实现他们的沟通技巧。

This research was carried out with the method of qualitative and descriptive indicators and analysis tailored to the problem solving based on the analysis of polya and using descriptive qualitative methods. The subject of this research totalled 33 learners class X SMK in Cimahi school year 2018/2019. The collection of data on research using the method of observation, test, and an interview. From the results of the tests and interviews it is known that the basic concept on reserved SPLDV students are still less so there is confusion in resolving the matter, because students can only understand the problem of 2.57%, drafting plans of 8.63%, making plans and corrects return of 15%, then the conclusion is that the problem-solving ability of the students of SMK owned is still low.

This study aims to determine the level of communication skills and mathematical creative thinking of junior high school students through tests of straight-line equation questions, and analyze the difficulties of students in solving problems in the matter of straight-line equations. The population in the study were all eighth grade students of Pasundan 1 Junior High School 1 Cimahi with a sample of 9 students in class VIII I who were taken using the proportionate stratified random sampling technique that is by taking samples from each strata proportionally randomly with the provisions of each of the 3 high-ability students , 3 students with moderate ability and 3 low-ability students. The research data was collected through a test of mathematical communication skills based on the indicators of 4 essay questions. The results showed students' mathematical communication skills of 34.4% included in the less category, while for creative thinking ability was 41% including sufficient categories. Based on the answer analysis students have been able to identify elements that are known and asked and stated them in mathematical symbols, able to identify the links between elements / data that are known and asked, only students have not been able to complete mathematical models and determine relevant solutions. Based on the results of the average questionnaire shows that students' self-confidence in mathematics learning can be categorized as being. These results are directly proportional to the results of tests of low mathematical communication skills and creative thinking abilities that are categorized sufficient.
