Problem-solving is an important competency that must be owned by students. Problem-solving skills can facilitate students in understanding, connecting, and using mathematical concepts. Even so, mistakes in solving mathematical problems are still made by students. One reason is the lack of habituation of problem-solving in learning mathematics. Teachers who have good problem-solving skills will find it easier to teach and do an activity about problem-solving in learning mathematics. The purpose of this study is to describe the problem-solving ability of primary school teachers based on Polya’s method. This research method is descriptive-qualitative. The research subjects were primary mathematics teachers who taught in Mataram City, Indonesia. Each research subject solved three mathematical problems correctly and the problem-solving process will be analyzed based on Polya's method. The results obtained are teachers from city and suburb schools doing three indicators, namely identifying information on the problem, carrying out the procedure according to plan, and doing calculations correctly. Indicators of problem-solving that are not done are writing problem questions, making mathematical models, and writing final conclusions.Kemampuan Pemecahan Masalah Guru Sekolah Dasar Berdasarkan Metode Polya di Kota MataramAbstrakPemecahan masalah adalah salah satu kompetensi yang cukup penting. Kemampuan pemecahan masalah dapat memudahkan siswa dalam memahami, menghubungkan, dan menggunakan konsep-konsep matematika. Meskipun begitu, kesalahan dalam pemecahan masalah matematika masih dilakukan oleh siswa. Salah satu sebabnya adalah kurangnya pembiasan pemecahan masalah pada pembelajaran matematika di sekolah. Guru yang memiliki kemampuan pemecahan masalah yang baik, akan lebih mudah mengajarkan dan membiasakan pemecahan masalah pada pembelajaran matematika di sekolah. Tujuan dari penelitian ini adalah untuk mendeskripsikan kemampuan pemecahan masalah pada guru SD di Kota Mataram. Metode penelitian ini adalah deskriptif-kualitatif. Subjek penelitian adalah guru matematika SD yang mengajar di pusat dan pinggiran Kota Mataram. Masing-masing subjek penelitian menyelesaikan tiga masalah matematika dengan benar dan akan dianalisis proses penyelesaian masalahnya berdasarkan metode Polya. Hasil yang didapatkan adalah guru dari sekolah kota dan pinggiran melakukan tiga indikator, yakni mengidentifikasi informasi pada masalah, melakukan prosedur penyelesaian sesuai rencana, dan melakukan perhitungan dengan benar. Indikator penyelesaian masalah yang tidak dilakukan adalah  menuliskan pertanyaan masalah, membuat model matematika, dan menuliskan kesimpulan akhir.

Because of the recent emphasis on rhetorical context in business and technical writing (BTW) instruction, the problem-solving case has become a staple in BTW classrooms. However, a number of critics have voiced concerns about the use of the rhetorical case. These concerns recall an ancient debate among Roman rhetoricians over an early case-study method called declamation. For contemporary theorists, the debate over case study revolves around its value as a stimulant to problem-solving skills, its ability to imitate the realistic circumstances of professional BTW, and its emphasis on persona and audience along with its deemphasis of the teacher. A full spectrum of arguments on these and other issues in the case-study debate indicates that the discipline is entering a new phase in its deliberations over the role of problem-solving and pragmatics in the BTW classroom.

This qualitative case study explores early childhood pre-service educators' perceptions of using play-based teaching strategy across the Foundation Phase. A play-based approach promotes a special mode of thinking, sense of possibility, ownership, control, and competence in maths and PE learners. That is why scholars believe that hybrid pedagogical content knowledge that integrates play-based learning sustains learner attention throughout the lesson and promotes problem-solving skills. Therefore, the main objective of this study is to propose alternative pathways that promote the implementation of a hybrid pedagogical teaching strategy in the Foundation Phase. This study draws from a qualitative case study conducted at one of the universities in KwaZulu-Natal to explore the perception of pre-service teachers about using a play-based teaching strategy in pre-Grade R and Grade R classes. Five preservice teachers who teach both mathematics and PE were purposively and conveniently sampled to generate data using narratives and semi-structured interviews to describe their perceptions and experiences. Zoom group meetings and WhatsApp one-on-one semi-structured interviews were used during the data generation process. The findings reveal that pre-service mathematics and PE teachers perceive play-based pedagogies as necessary to provide a wide range of opportunities for learners to learn to count, visualising groups, and problem-solving skills. They underscore the importance of drawing from a hybrid approach that draws strength from play-based learning to complement formal learning.

Most students experience different levels of difficulties in learning mathematics. TIMSS results have shown that most students in Ghana do not perform well in higher level tasks designed to assess applications and non-routine problems. This study, therefore, aimed at examining Ghanaian Junior and Senior High School mathematics teachers problem-solving strategies and their professional development needs about problem-solving. 114 mathematics teachers from 28 Junior High School (JHS) and Senior High School (SHS) in the Cape Coast Metropolis took part in the study. Quantitative and qualitative data were collected using a semi-structured questionnaire. The results from the study show that although teachers appreciate the importance of problem-solving in improving mathematics teaching and learning, there has not been the needed problem-solving training to support teachers in this regard. The researcher, therefore, argue that despite the numerous advantages associated with problem-solving strategy of teaching and learning, continuous professional development training for teachers should be paramount in our quest for helping students develop problem solving skills. Ghanaian JHS and SHS students can be in a disadvantageous position as they compete with their peers from other countries in international comparison examinations if our teachers are not given the needed support to become proficient in the use of problem-solving strategies in the classrooms.
