Analisis Kemampuan Kemampuan Penalaran dan Self Confidence Siswa SMA dalam Materi Peluang

This research is based on the level of mathematical reasoning ability and Self confidence which is owned by Students who are still relatively low. then the purpose of this study are: 1) to know the level of students\u27 reasoning ability seen from the achievement of minimum mastery criteria (KKM); 2) to know the students\u27 perceptions of each indicator of mathematical reasoning ability; 3) to know the level of Self confidence categories of students on each item statement. This research uses qualitative approach with explorative descriptive method. Subjects in this study were students of class XI IPS1 which amounted to 20 students in SMA Putra Juang academic year 2017/2018. The research instrument consisted of test question instrument, non test instrument in the form of questionnaire, and interview guide. From the research, it is found that the reasoning ability and self confidence of XI IPS1 SMA Putra Juang class students on the opportunity material are included in low category. This can be seen from the test results where the value of Students 75% below KKM and only 25% above KKM.Serta from the questionnaire that shows the ability of self-confidence mathematics owned 50% low students, 25% Medium, 20% High, and 5 % very high. whereas students \u27misconception in reasoning ability occurs in many indicators of students\u27 ability to construct and test a conjecture in mathematics lessons, where only 5 students reach this indicator of ability

Analisis Hubungan Kemampuan Pemecahan Masalah Matematis dan Self Confidence Siswa SMP

This study aims to analyze the achievement and improvement of problem solving skills of junior high school students through the application of guided inquiry method. This research is an experimental research with research design in the form of pretest-posttest Control Group Design, which is design of pretest-posttest control group involving two groups and sampling is done randomly class. Population in this research is all students in one of junior high school in Sukabumi Regency. The sample in this research is the students of class VIII SMPN 1 Sukaraja which has population characteristics. From all the existing classes VIII, two classes were chosen randomly to be sampled. The instrument used is the test of mathematical problem solving ability. Based on the result of the research, it can be concluded that the achievement of the problem solving ability of mathematical students in learning using guided inquiry method is better than the students who use ordinary learning. Then the improvement of students' mathematical problem solving skills in the learning using guided inquiry method is better than the students who use ordinary learnin
