AbstrakPenelitian ini bertujuan untuk mengetahui apakah terdapat pengaruh kemampuan verbal, penyesuaian diri, serta kemampuan verbal dan penyesuaian diri secara bersama-sama terhadap prestasi belajar matematika siswa. Penelitian ini merupakan penelitian ex-post facto menggunakan pendekatan kuantitatif. Populasi berasal dari 180 siswa kelas XI IPA SMA Negeri 8 Balikpapan. Penelitian ini menggunakan rumus Slovin dan mendapatkan 125 siswa yang terlibat sebagai sampel penelitian. Instrumen penelitian ini menggunakan tes dan angket. Data hasil penelitian dianalisis menggunakan regresi linear sederhana dan berganda. Hasil uji t menunjukkan bahwa nilai signifikansi sebesar 0,000 (Sig. < 0,05), sehingga dapat disimpulkan bahwa terdapat pengaruh kemampuan verbal terhadap prestasi belajar matematika siswa. Selanjutnya, hasil uji t menunjukkan bahwa nilai signifikansi sebesar 0,297 (Sig. > 0,05), sehingga dapat disimpulkan bahwa tidak terdapat pengaruh penyesuaian diri terhadap prestasi belajar matematika siswa. Kemudian, hasil uji F menunjukkan bahwa nilai signifikansi sebesar 0,000 (Sig. < 0,05), sehingga dapat disimpulkan bahwa terdapat pengaruh kemampuan verbal dan penyesuaian diri secara bersama-sama terhadap prestasi belajar matematika siswa. Selain itu, faktor kondisi seperti perubahan kebiasaan siswa yang awalnya belajar secara tatap muka di sekolah berubah menjadi pembelajaran secara online dapat mempengaruhi pencapaian prestasi belajar matematika siswa karena membutuhkan kesiapan dan penyesuaian diri yang matang pada siswa maupun pendidik. AbstractThe research aims to know the effect of verbal ability, self-adjustment, verbal ability and self-adjustment simultaneously toward student’s mathematic achievement. This research is ex-post facto research using a quantitative approach. The population came from 180 students of XI grade science class SMA Negeri 8 Balikpapan. This research used the Slovin formula and obtained 125 students involved a sample. This research used test and questionnaire as the instrument in this research. The data were analyzed using simple and multiple regression. The t-test result showed a significance value of 0,000 (Sig. < 0,05), so it could be concluded that there was an effect of verbal ability on students’ mathematic achievement. Next, the t-test result showed a significance value of 0,297 (Sig. > 0,05), so it could be concluded that there was no effect of self-adjustment on students’ mathematic achievement. Then, the F-test result showed a significance value of 0,000 (Sig. < 0,05), so it could be concluded that there was an effect of verbal ability and self-adjustment simultaneously on students’ mathematic achievement. Other than that, the condition factors such as changes in the habits of students who initially learn face-to-face at school turning into online learning can affect student achievement in mathematics learning because it requires mature readiness and adjustment in students and educators.

Penelitian ini bertujuan untuk mengetahui perbedaan pencapaian kemampuan pembuktian matematis siswa yang memperoleh pembelajaran Missouri Mathematics Project (MMP) dan yang memperoleh pembelajaran konvensional. Penelitian ini merupakan penelitian kuasi eksperimen dengan desain penelitian kelompok kontrol non-ekuivalen. Populasi dalam penelitian ini adalah seluruh siswa kelas VII pada salah satu SMP Negeri di Kota Balikpapan tahun ajaran 2013/2014. Sampel untuk penelitian ini diambil dari dua kelas yang terdiri dari satu kelas sebagai kelas eksperimen yang memperoleh pembelajaran Missouri Mathematics Project (MMP) dan satu kelas sebagai kelas kontrol yang memperoleh pembelajaran konvensional dengan menggunakan teknik purposive sampling. Analisis data dilakukan terhadap rata-rata skor post-test antara dua kelompok sampel. Analisis data kemampuan pembuktian matematis menggunakan uji non parametrik Mann whitney. Hasil analisis data menunjukkan nilai Sig. (1-tailed) < α = 0,05 sehingga H0 ditolak. Hal ini berarti kemampuan pembuktian matematis siswa yang memperoleh pembelajaran Missouri Mathematics Project (MMP) lebih baik daripada siswa yang memperoleh pembelajaran konvensional.

The purpose of the socialization of student development is to find out about the cognitive development of students and the development of students socially. The socialization was held at Melati Anugerah Indah Housing RT 49, Sepinggan Village, Balikpapan City, East Kalimantan Province. The target/target of the socialization is the residents of Melati Anugerah Indah Housing with the criteria of parents who have elementary school children. The socialization was carried out by conducting interviews, questions and answers and documentation. Technically, the team held a socialization activity in one of the residents' houses. Participants in the socialization included parents with 20 elementary school-aged children. Based on the results of interviews and questions and answers, the results showed that (1) the cognitive development of students is a process of developing knowledge experienced by students related to the ability to think logically in solving a problem faced by students. The knowledge experienced by students can be continuously honed with a continuous process of training and learning both at school and outside of school, with the hope that when students face a new problem, students are able to solve it. (2) the social development of students is the process of developing student interactions with other friends in order to establish kinship and kinship relationships so that students can get along with each other.

Self-regulated learning is the ability to direct and control oneself in thinking and acting and not feeling emotionally dependent on others. This study aims to determine the elements of online mathematics learning that cause students' self-regulated learning to strengthen and weaken. This type of research is a quantitative description with a population of all students of class VIII which is then selected by respondents as many as 67 students. The data was obtained through the distribution of questionnaires with google form. Based on the research conducted, it is known that the three elements of online mathematics learning that strengthen students' self-regulated learning are efforts to find learning resources, re-examine assignments before they are collected, and have targets to be achieved in the learning process. Meanwhile, the three elements of online mathematics learning that weaken students' self-regulated learning are group learning, help from friends when solving problems, and studying when there are exams.

The purpose of this study was to determine whether the perception of self-discipline has an influence on students' mathematics learning outcomes. This is cross sectional survey research with quantitative approach. The research sample was randomly selected from the population (N = 64) and 55 students were chosen based on the Isaac & Michael table. Questionnaires were used to collect data on perception of self-discipline and passed the validity test and reliability test (Cronbach's Alpha coefficient = 0.71; considered as high reliability). Whereas, the data of mathematics learning outcomes were obtained from daily mathematics exams. Simple linear regression statistical analysis was used to proceed the data and the result showed that 7 students had perception of self-discipline in low category, 35 students in medium category, and 13 students in high category. Also, the perception of self-discipline has a positive linear relationship with mathematics learning outcomes and contributes 31.8% of the variance of mathematics learning outcomes (R = 0.564; R2 = 0.318; β1 = 1.679; p < 0.05). This research recommended to improve students’ self-discipline in enhancing students' mathematics learning outcomes.
