Perkembangan teknologi yang pesat mendorong terjadinya pergeseran paradigma dalam proses pembelajaran matematika, di mana pembelajaran daring menjadi salah satu pilihan yang sering dilakukan. Hal tersebut berimplikasi pada adanya perubahan kerangka Pedagogical Content Knowledge (PCK) guru dalam pembelajaran matematika. Penelitian ini bertujuan untuk mendeskripsikan kerangka PCK guru dalam pembelajaran matematika daring. Penelitian ini menggunakan metode analisis konten yang digunakan untuk merancang kerangka konseptual PCK guru dalam pembelajaran matematika daring. Analisis konten yang dilakukan berupa literatur review dan penggalian data. Untuk penggalian data, digunakan instrumen berupa angket dan pedoman wawancara dengan subjek sebanyak lima orang guru matematika. Teknik analisis data yang digunakan, yaitu triangulasi. Hasil penelitian menunjukkan bahwa kerangka PCK guru dalam pembelajaran matematika daring dapat diadaptasi dan dioperasionalkan dari model PCK Lannin yang meliputi: knowledge of instructional strategies for mathematics, knowledge of student understanding within mathematics, knowledge of curriculum for mathematics dan knowledge of assessment for mathematics. Guru sudah memiliki paradigma, kesiapan dan faktor pendukung yang cukup baik dalam melaksanakan pembelajaran matematika daring, namun masih belum optimal dalam kemampuan dan struktur tugas siswa. Rapid technological developments encourage a paradigm shift in the mathematics learning process, where online learning is one of the choices that is often done. This implies a change in the teacher's Pedagogical Content Knowledge (PCK) framework in learning mathematics. This study aims to describe the PCK framework of teachers in online mathematics learning. This study uses the content analysis method used to design the conceptual framework of teachers' PCK in online mathematics learning. Content analysis is carried out in the form of a literature review and data mining. For data mining, instruments in the form of questionnaires and interview guidelines were used with the subject of five mathematics teachers. The data analysis technique used is triangulation. The results showed that the teacher's PCK framework in online mathematics learning can be adapted and operationalized from Lannin's PCK model which includes: knowledge of instructional strategies for mathematics, knowledge of student understanding within mathematics, knowledge of the curriculum for mathematics and knowledge of assessment for mathematics. Teachers already have a fairly good paradigm, readiness, and supporting factors in implementing online mathematics learning, but they are still not optimal in the abilities and structure of students' assignments.

Abstract:
AbstrakMempelajari matematika dianggap sulit oleh mayoritas siswa. Solusinya, peneliti menerapkan sebuah pendekatan pembelajaran kontekstual. Penelitian ini bertujuan untuk menyelidiki faktor-faktor penyebab kesulitan siswa dalam mempelajari materi perbandingan. Penelitian deskriptif kualitatif ini menggunakan instrumen soal cerita berjumlah 3 soal. Subjek penelitian adalah 24 orang siswa yang dipilih secara purposive sampling pada salah satu SMP di Kabupaten Bandung Barat. Pengumpulan data dilakukan dengan menggunakan tes dan wawancara. Hasil penelitian kemudian dianalisis secara deskriptif untuk mencapai tujuan penelitian. Hasil penelitian menunjukkan bahwa siswa SMP Pasundan Rongga belum sepenuhnya mencapai target yang diharapkan. Siswa masih banyak yang mengalami kesulitan untuk menyelesaikan soal cerita. Kesulitan siswa yang dominan dapat dikategorikan ke dalam tiga bentuk, yaitu kurangnya pemahaman konsep, tergesa-gesa menyelesaikan soal, dan kurangnya memahami soal. Berdasarkan hasil wawancara, penyebab kesulitan tersebut karena siswa belum terbiasa diberikan soal berbentuk cerita. Soal cerita perlu lebih sering diberikan kepada siswa guna menambah pengalaman belajarnya. AbstractLearning mathematics is considered difficult by the majority of students. The solution, researchers apply a contextual learning approach. This study aims to investigate the factors that cause students' difficulties in studying comparative material. This qualitative descriptive study used three-story questions as instruments. The research subjects were 24 students who were selected by purposive sampling at one of the junior high schools in West Bandung Regency. Data collection was carried out using tests and interviews. The research results were then analyzed descriptively to achieve the research objectives. The results showed that the students of SMP Pasundan Rongga had not fully achieved the expected targets. There are still many students who have difficulty solving story questions. The students' dominant difficulties can be categorized into three forms, namely a lack of understanding of the concept, rushing to solve the problem, and a lack of understanding the problem. Based on the results of the interview, the cause of the difficulty was because students were not used to being given questions in the form of stories. Story questions need to be given to students more often in order to increase their learning experience.

Abstract:
AbstrakPentingnya kemampuan pemecahan masalah dalam pembelajaran matematika belum diikuti dengan pencapaian yang baik. Penelitian ini bertujuan menerapkan model pembelajaran Problem Solving dan Problem Posing serta menguji ada tidaknya perbedaan kemampuan pemecahan masalah dari kedua model tersebut. Penelitian dilaksanakan pada kelas X salah satu SMA Negeri di Salatiga dengan materi trigonometri. Sampel sebanyak 53 siswa, terbagi dalam dua kelompok eksperimen. Penelitian ekperimen semu ini menggunakan desain randomaized control group pretest-postest design, dengan instrumen berbentuk tes kemampuan pemecahan masalah dan lembar observasi. Analisis data menggunakan kovariansi pada taraf signifikan 𝛼 = 5% dengan kemampuan awal sebagai variabel kovarian. Hasil uji hipotesis menyimpulkan bahwa dengan mengontrol kemampuan awal siswa didapat bahwa siswa yang melaksanakan model pembelajaran Problem Posing secara signifikan memiliki kemampuan pemecahan masalah matematika yang lebih baik dibandingkan siswa yang melaksanakan model pembelajaran Problem Solving. Hasil ini menunjukkan pembelajaran hendaknya tidak hanya melatih siswa menyelesaikan masalah tetapi juga mengkonstruksi permasalahan. Differences in problem-solving abilities from the application of problem-solving and problem-posing in high school studentsAbstractThe importance of problem-solving abilities in mathematics learning has not been automatically followed by good achievement. This study aims to apply Problem Solving and Problem Posing learning models and to test whether there are differences in the problem-solving abilities of the two learning models. This research was conducted in class X mathematics learning at one of the public high schools in Salatiga on Trigonometry material. This quasi-experimental study used a randomized control group pretest-posttest design, with instruments in the form of problem-solving ability tests and observation sheets. The data analysis used was the covariance test at the significant level α = 5% with the initial ability as a covariate variable. The results of hypothesis testing with covariance analysis concluded that by controlling students' initial abilities it was found that there were significant differences in mathematical problem-solving abilities between the application of the two models. Students who carry out the Problem Posing learning model significantly have better mathematical problem-solving abilities than students who carry out the Problem-Solving learning model. These results indicate that learning should not only train students to solve problems but also construct problems.

Pola permisif terlihat dari kegiatan pembinaan yang memberikan kesempatan bagi siswa secara terbuka untuk menambah kemampuan di luar pembinaan di sekolah. Terakhir adalah pola demokratis, yang terlihat saat sebagian besar proses pembinaan diawali pemberian materi, lalu siswa diberi kesempatan menyelesaikan soal latihan. Selanjutnya dilakukan pembahasan soal yang telah dikerjakan siswa. AbstractThere are still many teachers who are confused about determining the pattern of coaching they should do. This research aims to determine the pattern of fostering the National Mathematical Science Olympiad (OSN) Junior High School in the Ponorogo Regency. This is qualitative descriptive research. The sample selection is done by purposive sampling. The instrument used was an interview sheet. Data analysis was performed descriptively qualitatively. The pattern of fostering the OSN Mathematics Junior High School in the Ponorogo Regency is carried out in three coaching patterns, namely authoritarian, permissive, and democratic. In the authoritarian pattern, it can be seen from the school's policy in developing a coaching program, the selection process, to the rewards given when passing OSN selection at the district level. Permissive patterns can be seen from coaching activities that openly provide opportunities for students to add skills beyond coaching at school. The last is a democratic pattern, which is very visible when most of the coaching process begins with the provision of material, then students are allowed to complete practice questions. Then a discussion on the questions the students have done is only done.

Abstract:
AbstrakBerbagai penelitian mengemukakan kemampuan berpikir kreatif matematis siswa masih rendah. Siswa hanya mencontoh apa yang dikerjakan guru, tanpa makna, sehingga dalam menyelesaikan soal, siswa menganggap cukup mengerjakan seperti apa yang dicontohkan. Tujuan dari penelitian ini untuk mendapatkan bukti empiris serta mengetahui bagaimana peningkatan kemampuan berpikir kreatif matematis siswa dengan penggunakan model pembelajaran Creative Problem Solving. Metode penelitian yang digunakan dalam penelitian ini adalah kuasi eksperimen dengan satu kelas sebagai kelas eksperimen. Instrumen yang digunakan dalam penelitian ini berupa soal tes uraian yang diberikan sebelum dan setelah diterapkannya model pembelajaran, dengan pokok bahasan materi fungsi. Populasi pada penelitian ini adalah seluruh siswa kelas X SMAN 25 Garut dengan sampel satu kelas yaitu, kelas X MIA 3 sebanyak 32 siswa, diambil secara purposive sampling. Hasil penelitian menunjukan bahwa secara statistik peningkatan kemampuan berpikir kreatif matematis kelas Creative Problem Solving bartaraf sedang, maka dapat disimpulkan bahwa terdapat peningkatan kemampuan berpikir kreatif matematis siswa yang menggunakan model Creative Problem Solving. Enhanced Ability of Student Mathematical Creative Thinking with Creative Problem SolvingAbstractDifferent studies propose that students' mathematical creative thinking abilities are still weak. Students only imitate what the teacher is doing, without meaning, so that in solving problems, students assume enough to do as what is explained. The objective of this study is to obtain empirical evidence and find out how to enhance students' mathematical creative thinking abilities by using the Creative Problem Solving learning model. The study method is a quasi-experiment with one class as an experimental class. The instrument was in the form of a test item given before and after the learning model was performed, with the subject theme functioning. The population in this study were all students of class X SMAN 25 Garut with a sample of one class that is, class X MIA 3 as many as 32 students, taken by purposive sampling. The outcomes of the study revealed that statistically increasing the ability to think mathematically in a creative class of moderate problem-solving problem, it can be assumed that there was an improvement in students' mathematical creative thinking ability using the model of creative problem-solving.

Abstract:
AbstrakMasalah dalam penelitian ini adalah rendahnya Kemampuan Koneksi Matematis (KKnM) siswa dan pembelajaran terlaksana cenderung bersifat konvensional. Suatu alternatif mengoptimalkan kemampuan bermatematika siswa dan perbaikan proses pembelajaran yaitu mempertimbangkan penerapan pendekatan pembelajaran dengan pendekatan open-ended. Penelitian ini bertujuan untuk mendeskripsikan apakah terdapat interaksi Kemampuan Awal Matematika (KAM) dan gender dengan pendekatan pembelajaran dalam membelajarkan KKnM siswa. Penelitian merupakan penelitian eksperimen semu dengan rancangan Nonequivalent Control Group Design. Instrumen yang digunakan adalah essay test KKnM siswa.
