Abstract

This research is motivated by the still low level of mathematical critical thinking skills of State Middle School students in Cimahi City, so a learning approach is needed to overcome these problems. Alternative approaches are applied, namely the approach to Model-Eliciting Activities. This study aims to examine the mathematical critical thinking skills of State Middle School students in Cimahi City. The method used in this study is an experimental method with research in the form of a pretest-posttest Control Group Design. The population in this study were all public junior high schools in the city of Cimahi randomly selected and selected SMP Negeri 10 Cimahi representing the characteristics of the population. The sample was chosen by two classes in a random class, namely the experimental class and the control class. Data collection in this study used a descriptive test, then the score data of the students' mathematical critical thinking skills were analyzed by descriptive and inferential statistics using the two average difference test. Based on the results of the study, both from the results of data analysis and hypothesis testing, it can be concluded that the mathematical critical thinking skills of the State Middle School students in Cimahi City whose learning using the MEAs approach are better than those using conventional learning.

Abstract

This study aims to identify and analyze aspects of the communication skills of vocational students in the material system of two-variable linear equations. The samples taken in this study were 5 students from a population of 30 students with different abilities and were taken randomly at one of the West Bandung Vocational Schools, namely class X Computer Engineering Network 2 SMK BINA INSAN BANGSA. The type of research used is qualitative descriptive. The research instrument is a test question of mathematical communication skills in the form of 4 items essays and interviews. Test results that have been carried out on several mathematical communication questions still show results below the average. It can be seen from the percentage of scores per item, namely the question no.1, obtained a percentage of 60% for indicators in explaining ideas, situations orally or in writing with real objects, graphic images, and algebra. Problem no.2 with the acquisition of 35% percentage for indicators to solve problems with the rules used. Question number 3 with the acquisition of a 25% percentage for indicators expressing daily events in mathematical language. Problem no.4 obtained a percentage of 15% for indicators connecting graphs with mathematical ideas. Then it can be concluded that the level of communication skills of vocational students is still not good enough and is classified as low because there are two problem indicators in the low category ≤ 33%

Abstract

Independence of Learning towards Mathematics Learning Outcomes in SMK 1 Cihampelas. The research method used in this study is a survey method using correlational analysis. Samples were obtained by using simple random sampling techniques totaling 35 students from class X of SMK 1 Cihampelas. Data collection is done using questionnaires and PTS tests. Data analysis was performed using SPSS 23 program assistance consisting of descriptive analysis analysis, test requirements for data analysis and hypothesis testing. Requirements test for data analysis used, namely normality test, and linearity test. Based on the results of the study, conclusions were obtained about the significant positive results between learning independence towards mathematics learning outcomes. The contribution of learning independence to mathematical results is 16% and the remaining 84% is contributed by other variables besides learning independence.

Abstract

Students' negative suggestions for mathematics make mathematics not so much liked and desired by students. Critical thinking ability is very important to have, because it can help us in thinking rationally in overcoming the problems we face. This study aims to analyze the independence of learning and critical thinking mathematically students at Al-Mukhtariyah Mande Mts. This study used descriptive qualitative method. Researchers act as observers, provide test questions and provide questionnaires to students. The instruments used are a description test and a learning independence scale. The study was conducted on class VIII students, namely in class VIII-B and VIII-D at the Al-Mukhtariyah Mande Mts. In class VIII-B, there were 25 students, 13 students were male and 12 were female students. In class VIII-D, there were 33 students, 15 students were male and 18 were female students. Researchers use indicators of critical thinking: interpretation, analysis, evaluation, drawing conclusions, explanations, independence. Based on the results of the description test, it was concluded that (1) students 'overall mathematical critical thinking ability was in the low category, (2) students' responses in solving critical thinking problems were still very low, (3) overall student learning independence was at a moderate level and students are not accustomed to using indicators of independence of learning correctly. (4) there is a close relationship between learning independence and students' critical thinking skills

Abstract

This research aims to analyze and in study about influence of mathematical by self regulated learning against the ability of mathematical creative thinking high school students. The methods used in this research is quantitative data with the correlational method. The population in this research is a high school student in the city of Karawang with sampels as many as 32 student that assigned by techniques purposif sampling at one high school in the city of Karawang.
