The purpose of this research are: (1) to know the influence of Think Talk Write (TTW) model of learning ability to solve mathematical problems of learners; (2) to know the effect of learning habit on students' mathematical problem solving ability; (3) to know the interaction between learning model and study habit to students' mathematical problem solving ability. The type of research used is quasi experiment with 3 × 3 factorial research design. The hypothesis test used is a parametric test with data analysis technique using Anova test. The result of the research for the prerequisite test is based on normality test which can be known by using Liliefors test and homogeneity test can be known by using Barlett test, it is obtained that the test result data from both groups are normal and homogeneous, so it can be continued for parametric test by using anava test two paths with unequal cells. Based on data processing, it is found that: (1) there is influence of Think Talk Write (TTW) learning model to students' mathematical problem-solving ability; (2) there is the influence of learning habit on the ability of mathematical problem of learners; (3) there is no interaction between the learning model and the learning habits of the mathematical problems of the learners. This means that the learning model Think Talk Write (TTW) is more effective than the conventional model so that Think Talk Write (TTW) model more influence on the problem-solving ability of learners.

This study aims to examine the effectiveness of counseling interventions using self-information to increase student career certainty. This study was conducted with a quasi-experimental pre-test–post-test non-equivalent group design. The number of subjects was 94 high school students, out of which 44 were male and 50 were female; the experimental group consisted of 39 people and the control group consisted of 55 people. The Self-information used in this study was provided through the Self-Directed Career Exploration Inventory, while research data was obtained through the Career Plan Certainty Scale. The results showed that career counseling services using self-information were effective in helping high school students to increase their career choice certainty. The mean score of the students of the specialization group in the experimental group increased and was significantly different from the mean score of the students in the control group. In addition, the mean score for the study plans of male and female students was not significantly different.   Keywords: Career certainty, self-information, career counseling, career intervention.

Penelitian ini bertujuan untuk menghasilkan media dalam modul berbasis Islam pada materi Aritmatika Sosial dalam meningkatkan pemahaman konsep matematika siswa. Metode penelitian yang digunakan adalah Research and Development (R&D) dengan model pengembangan ADDIE. Tahapan yang dilakukan adalah Analisis, Desain, Pengembangan, Implementasi, dan Evaluasi. Data penelitian diperoleh dengan menggunakan kuesioner, wawancara, dan tes khusus. Hasil penilaian berdasarkan angket validasi ahli materi untuk modul ini termasuk dalam kategori “Valid” dengan skor rata-rata 83%. Penilaian ahli media memperoleh skor rata-rata 87% dalam kategori “Valid”. Pada uji coba lapangan skala besar diperoleh rata-rata 83% dengan kriteria “Menarik”. Kualitas keefektifan produk dilihat dari tes hasil belajar. Hasil analisis data dengan menggunakan uji-t pembelajaran menggunakan modul matematika berbasis Islam yang diterapkan di kelas VII 1 lebih efektif daripada di kelas VII 2 yang pendidikannya tidak menggunakan modul matematika berbasis Islam. Hasil analisis menggunakan N-Gain adalah peningkatan pemahaman konsep matematika siswa. Berdasarkan hasil tersebut dapat disimpulkan bahwa modul berbasis Islam adalah valid (layak), menarik, praktis untuk digunakan sebagai sumber belajar, dan dapat meningkatkan pemahaman konsep matematika siswa.  This study aims to produce media in Islamic-based modules on social arithmetic material in improving students' understanding of mathematical concepts. The study method used is Research and Development (R&D) with the ADDIE development model. The stages carried out are Analysis, Design, Development, Implementation, and Evaluation. The research data was obtained using questionnaires, interviews, and special tests. The assessment results based on a material expert validation questionnaire for this module are included in the "Valid" category with an average score of 83%. The media expert's assessment obtained an average score of 87% in the "Valid" category. In a large-scale field trial, an average of 83% was obtained with the "Attractive" criteria. The quality of the product's effectiveness is seen from the learning outcomes test. The results of data analysis using t-test learning using Islamic-based mathematics modules that are applied in class VII 1 are more effective than in class VII 2, whose education does not use Islamic-based mathematics modules. The analysis results using N-Gain are an increase in students' understanding of mathematical concepts. Based on these results, it can be concluded that Islamic-based modules are valid (feasible), attractive, practical to be used as learning resources, and can improve students' understanding of mathematical concepts.

This study aims to analyze and describe the mathematical communication skills of junior high school students reviewed from gender and school origin. This reaserch is a qualitative descriptive study, with the subject of the study being the eighth grade students of Pasir Sakti State 2 Junior High School, which subject of study eight students, namely 4 students from State elementary schools (2 males and 2 females) and 4 students from Private elementary schools (2 males and 2 females). The data collection technique was mathematical communication skills tests used the data presentation material consisting two questions. The research data was collected by researchers directly. Technique of data analysis in this study are Data Reduction, Data Display, and Conclusions Drawing/Verification. The results showed: The mathematical communication skills of junior high school students overall are (1) The ability of female students were higher than male students with a difference of 11.11%. (2) The ability of students from public elementary schools were higher than students from private elementary schools with a difference of 2.78%. (3) The ability of students in Drawing aspect were higher than Written Text aspect, and Mathematical Expression aspect.
