This study is a survey research using quantitative approach. The subject in this study was eighth grade students with 132 students. Data in this study were collected using two instruments, namely mathematics reasoning ability tests and self-efficacy questionnaires. Analysis of the data in this study was divided into two parts, namely descriptive analysis and inferential analysis. Descriptive analysis described of mathematical reasoning ability and self-efficacy. Inferential analysis used Pearson product moment correlation test to find relationship between self-efficacy and mathematical reasoning ability. The results of the study showed that the students' self-efficacy was in high category and the strength aspect was the dimension of self-efficacy with the highest score. In mathematical reasoning ability, the ability of students to give correct and complete evidence of solutions has the highest score. The result of correlation test showed that there was relationship between self-efficacy and mathematical reasoning ability with a positive relationship

ABSTRACT For the development of education towards more advanced learning mathematics sought metacognitive learning. Learning that can build students' perspectives on mathematical problems, by thinking of an appropriate strategy. Then, from the knowledge obtained by the student is able to draw conclusions or reasoning, in this case the achievement of students' mathematical reasoning abilities. This study aims to determine the achievement of the reasoning ability of students who are given learning with a metacognitive approach and students who are given conventional learning. This study uses an experimental method conducted on eighth grade students of SMP Negeri 3 Kalijati. The sample selection is done randomly by selecting two classes from three classes. Of the two classes selected, class VIIIC as an experimental class whose learning uses a metacognitive approach and class VIIIB as a control class whose learning uses conventional learning models. To determine the ability of the two classes are given a preliminary test and a final test with the same questions. The results of the study concluded that students' reasoning abilities on the subject of the circle using learning metacognitive approaches were higher than using conventional learning.     ABSTRAK Untuk pengembangan pendidikan kearah lebih maju dalam pembelajaran matematika diupayakan suatu pembelajaran metakognitif. Pembelajaran  yang dapat membangun cara pandang siswa terhadap masalah matematika, dengan memikirkan suatu strategi yang tepat. Kemudian, dari pengetahuan yang diperoleh siswa tersebut mampu mengambil kesimpulan atau penalaran, dalam hal ini pencapaian kemampuan penalaran matematika siswa. Penelitian ini bertujuan untuk mengetahui pencapaian kemampuan penalaran siswa yang diberi pembelajaran dengan pendekatan metakognitif dan siswa yang diberi pembelajaran konvensional. Penelitian ini menggunakan metode eksperimen yang dilakukan pada siswa kelas VIII SMP Negeri 3 Kalijati. Pemilihan sampel dilakukan secara acak dengan memilih dua kelas dari tiga kelas. Dari dua kelas yang terpilih, kelas VIIIC sebagai kelas eksperimen yang pembelajarannya menggunakan pendekatan metakognitif dan kelas VIIIB sebagai kelas kontrol yang pembelajarannya menggunakan model pembelajaran konvensional. Untuk mengetahui kemampuan dari kedua kelas tersebut diberi tes awal dan tes akhir dengan soal yang sama. Hasil penelitian menyimpulkan bahwa kemampuan penalaran siswa pada pokok bahasan lingkaran menggunakan pembelajaran pendekatan metakognitif lebih tinggi daripada menggunakan pembelajaran konvesional.

Academic Self Efficacy

Academic self-efficacy is important for students which will help them to perform better in studies. This study aims to explore the level of academic self-efficacy among UNIMAS undergraduates based on gender, CGPA and trait emotional intelligence. The samples of study involved are 50 male and 50 female participants which consists of final year students from Faculty of Cognitive Sciences and Human Development. The academic self-efficacy of the students is measured using the questionnaire adopted from a study by Sachitra and Bandara (2017) and The Short Form (TEIQue-SF) Trait Emotional Intelligence Questionnaire is used to measure the trait emotional intelligence of the undergraduates. The result was analyzed using descriptive analysis and inferential analysis; independent samples t-test, One-Way ANOVA and Pearson’s correlation. The results of the study have shown that female students have higher academic self-efficacy compared to male students. In addition, students who obtain a higher CGPA also have higher self-efficacy. There was also a small positive correlation between trait emotional intelligence and academic self-efficacy.

This research is aimed to find out the implementation of Team Game Tournament to improve students’ classroom interaction and reading comprehension viewed from self-efficacy. The subject of this study was 30 students at second grade students of SMPN 5 Kopang. Which consists of 14 males and 16 females. This study was classroom action research (CAR) with two cycles, each cycle consists of four steps: planning, acting, observing and reflecting. The first cycle was focused on the students’ classroom interaction. Meanwhile, the second cycle was oriented to solve the students’ improvement of reading comprehension. The data gathering used reading test, observation sheet, and questionnaires and analyzed by using quantitative and qualitative approach. The result of the questionnaire showed the students score in the first cycle was 16.86 or 56% and the second cycle showed the students' score was 27.10 or 90.3% indicating the target of 75 of the minimum criterion has been achieved, it means that the action was stopped in the cycle 2. In other words, the students’ classroom interaction and reading comprehension in relation to self-efficacy was improved by implementing team game tournament (TGT) for the eighth-grade students of SMPN 5 Kopang.

The aim of this study is to describe the mathematical reasoning ability of students at TSM major (Motorcycle Engineering) Darul Karomah Singosari on square root material. This study applies descriptive qualitative approach, data was collected using test instrument that has been tested on three research subjects, and analyzed using qualitative descriptive technique. The results show that low- ability (Kemampuan Rendah) subject is the student with less mathematical reasoning ability because the subject has not been able to solve the five existing indicators of mathematical reasoning, middle- ability (Kemampuan Sedang) subject include student with moderate mathematical reasoning ability (although the subject has not fulfilled the five indicators of mathematical reasoning requirements), this can be seen from his effort to make a mathematical assumption even though the conjecture made was not correct, and high- ability (Kemampuan Tinggi) subject refers to the student with high mathematical reasoning ability because he can fulfill two of the five indicators of mathematical reasoning.
