This research aimed to: 1) compare the mathematical critical thinking skills of students who were taught with the Problem Based Learning model assisted by open-ended problems and students who were traditionally taught, 2) investigate the interaction between problem based learning models with mathematical attitudes towards students' mathematical critical thinking abilities. It was a quantitative study using a quasi-experimental method with a 2 x 2 factorial design and was conducted at SMA Negeri 1 Cibal, Manggarai district, East Nusa Tenggara. Two classes were experimental and two classes were control and were chosen using cluster random sampling techniques. Data were obtained through questions to measure mathematical critical thinking skills and mathematical attitude questions and then analyzed with two way ANOVA. The data analysis and interpretation showed that 1) the mathematical critical thinking skills of students who were taught with the Problem Based Learning model assisted by open-ended problems were better than those of students who have been traditionally taught 2) there was no interaction between the problem based learning model and students' mathematical critical thinking abilities. This means that both students who had high and low mathematical attitudes scores when taught with the Problem Based Learning approach assisted with open-ended problems were always better than students who are taught with conventional approaches.BAHASA INDONESIA ABSTRACT: Penelitian ini bertujuan untuk; 1) membandingkan kemampuan berpikir kritis matematika siswa yang mengikuti model problem based learning berbantuan masalah open-ended dengan kemampuan berpikir kritis matematika siswa yang mengikuti pembelajaran konvensional. 2) melihat interaksi antara model problem based learning dengan sikap matematis terhadap kemampuan berpikir kritis matematika siswa. Penelitian ini merupakan penelitian eksperimen semu (quasi experiment) dengan rancangan factorial 2 x 2. Populasi dalam penelitian ini adalah siswa kelas X SMA Negeri 1 Cibal kabupaten Manggarai, Nusa Tenggara Timur. Pengambilan sampel dilakukan dengan menggunakan teknik cluster random sampling, 2 kelas sebagai kelas eksperimen dan 2 kelas sebagai kelas kontrol. Instrumen penelitian yang digunakan berupa tes kemampuan berpikir kritis matematika dan tes sikap matematis. Data yang telah terkumpul dianalisis dengan menggunakan uji Anava Dua Jalur. Sebelum digunakan uji anava dua jalur, data tersebut terlebih dahulu dilakukan uji normalitas dan homogenitas. Hasil penelitian ini menunjukkan; 1) kemampuan berpikir kritis siswa yang mengikuti pembelajaran matematika dengan model Problem Based Learning berbantuan masalah open-ended lebih baik daripada siswa yang mengikuti pembelajaran matematika dengan pendekatan konvensional; 2) tidak terdapat interaksi antara pendekatan pembelajaran Problem Based Learning dengan sikap matematis siswa terhadap kemampuan berpikir kritis matematika siswa. Artinya baik siswa yang memiliki sikap matematis tinggi maupun yang memiliki sikap matematis rendah apabila diajarkan dengan pendekatan pembelajaran Problem Based Learning berbantuan masalah open-ended selalu lebih baik dibanding siswa yang dibelajarkan dengan pendekatan konvensional.

Penelitian ini bertujuan mengungkapkan hubungan teoretis antara kecemasan matematika guru dan respon siswa terhadap kinerja guru dalam proses pembelajaran. Penelitian mix-method ini melibatkan dua orang calon guru matematika, yaitu HA dan LA. HA mempunyai tingkat kecemasan matematika tinggi, sedangkan LA mempunyai tingkat kecemasan matematika rendah. Selain itu, penelitian ini juga melibatkan 64 orang siswa yang ditugaskan untuk menilai kinerja HA dan LA. Instrumen yang digunakan adalah angket, tes, penugasan, pengamatan, dan wawancara. Teknik analisis data yang digunakan yaitu analisis deskriptif dan uji chi-square. Hasil analisis deskriptif memperlihatkan bahwa 97% siswa memberikan respon positif terhadap kinerja LA, dan hanya 76% siswa yang memberikan respon positif terhadap kinerja HA. Selain itu, hasil analisis memperlihatkan bahwa nilai = 45,86 > nilai kritis =3,84, yang berarti bahwa ada perbedaan yang signifikan respon siswa terhadap kinerja kedua orang guru. Berdasarkan hasil analisis ini disimpulkan bahwa siswa memberikan respon yang lebih baik terhadap guru dengan tingkat kecemasan matematika lebih rendah.

TPCK is knowledge that can be used by teachers in integrating technology appropriately in the learning process based on the description of material character and pedagogical aspects. This study aims to describe the ability of Technological Pedagogical Content Knowledge (TPCK) Teachers. The method used is descriptive with a qualitative approach. The sampling technique used in this study was purposive sampling technique. Therefore, the schools used as samples in this study were SMAN I Kuwus, SMAN 2 Kuwus (Hawe) and SMAN 1 About. Data were collected by observation, interview, and documentation. Data analysis techniques used in this study include data collection, data reduction, data presentation, and conclusion drawing. Teachers' TPACK ability can be seen through the six TPACK indicators that have been previously determined. Nevertheless, there are still obstacles in implementation such as the lack of sequential application of learning model strategies and the number of devices owned by the school. This constraint is utilised by teachers to remain more creative in the teaching process.

This study aims to describe mathematical communication skills in terms of gender and personality type of grade VII students of SMPN 5 Langke Rembong. This research is qualitative research using a descriptive approach. The study subjects consisted of 4 people with details of 2 male subjects and 2 female subjects with introvert-extrovert personality type. The data collection techniques used are tests, questionnaires, and documentation. Data analysis techniques using the Miles & Huberman model data analysis, namely data reduction, data presentation, and conclusions. The validity of the data in this study used triangulation (sources and techniques). The results showed that both male and female students were able to express mathematical ideas in writing correctly and completely, were able to evaluate mathematical ideas in solving the problem correctly, and the solution steps were written sequentially, completely, and correctly, and were also able to write the conclusion of solving the problem given. However, when viewed from the personality type of male subjects with extroverted types, they were less superior in evaluating mathematical ideas, especially in the aspect of writing the formula used to solve the problem.
