“…Thus it can be concluded that the relationship between problemsolving and Project-Based Learning based on student learning outcomes is very strong, problem-solving and PjBL also have a "positive or unidirectional" relationship pattern.The mastery of student learning is also related to the mastery of the pre-test and post-test learning indicators, most of the students are weak in the indicators of planning and solving problem-solving solutions. Based on Saputri and Mampouw (2018) that before compiling a problem-solving plan, the subject must plan what stages are needed and look for references to concepts and theories that support problem-solving. The advantages of Project Based Learning can bridge students to develop creativity through problem solving activities in the form of projects (Kusumaningrum, 2016).…”

Problem solving skills are needed by students to solve problems that arise in everyday life. Innovation in learning is needed so that students can achieve the basic competencies and apply 21st-century skills, in the form of interactive, collaborative learning models. One of the innovations is using the Project-Based Learning learning model with the E-book of plant anatomy structures. This study aims to develop an E-book of PjBL-based plant anatomy structures to practice problem-solving skills which are declared valid in terms of theoretical and empirical aspects. The theoretical aspect is viewed from the results of the validity. Empirical aspects in terms of learning outcomes, student responses, and readability. The development model used is 4D. The research was carried out at the UNESA Postgraduate Program in June-August 2020. The target of this research was an online E-book on the structure of plant anatomy based on Project Based Learning which was tested on ten students of Muhammadiyah 1 Gresik senior high school in February 2021. The instruments used were validation sheets, student response sheets, and fry chart sheets. The data were analyzed descriptively quantitatively. The results showed that the PjBL-based E-book of plant anatomical structures was theoretically feasible based on the validation results obtained an categories very valid and empirically feasible based on student learning outcomes (N-gain of moderate categories). Based on this description, a PjBL E-book of plant anatomy structures to train students' problem-solving skills is feasible theoretically and empirically.

“…Berdasarkan wawancara diketahui penyebab siswa melakukan kesalahan process skill karena tidak bisa mengintegralkan soal yang memuat bilangan pecahan. Hasil penelitian ini relevan dengan penelitian Saputri & Mampouw (2018) bahwa siswa berkemampuan rendah kesulitan dalam mengoperasikan pecahan. Tingginya tingkat kesalahan yang dilakukan siswa pada tahap encoding dikarenakan kesalahan yang dilakukan siswa pada tahapan kesalahan sebelumnya seperti tahap transformation dan process skill.…”

This study aims to describe errors in solving indefinite integral problems of algebraic functions based on Newman's procedure in terms of the category of mathematical ability. This type of research is descriptive with a qualitative approach. The research subject is class XII IPS 1 SMAN 5 Mataram in the academic year 2022/2023. The results showed (1) High-ability students made mistakes at the process skill stage due to the lack of giving practice questions using the partial method. (2) Students who are capable are making mistakes at the transformation stage due to incorrectly substituting the values obtained at the example stage, and errors in the process skill stage because they cannot simplify terms containing the variable x. (3) Low-ability students make mistakes at the reading stage because they don't know the mention of the "∫" symbol, errors in the comprehension stage because they don't understand the question commands, and errors in the process skill stage because they can't operate fractions. errors at the reading stage because they could not read the symbol "∫", errors at the comprehension stage because they did not understand the meaning of dy and did not understand determining the term to be used, errors at the transformation stage due to not being able to change the form of the question to match the formula for the substitution method and partial as well as errors at the process skill stage for not understanding the steps of the substitution and partial method.

“…Pecahan di tingkat sekolah dasar dipelajari mulai dari kelas II sampai dengan kelas VI yang termasuk ke dalam kompetensi bilangan dimulai dari pecahan dasar sampai kompleks serta di tingkat SMP pecahan dipelajari kembali di kelas VII dengan muatan materi yang lebih kompleks (Indriani, 2016;Liestarie & Karlimah, 2017;Peraturan Menteri Pendidikan dan Kebudayaan Republik Indonesia, 2018;Saleh, Prahmana, Isa & Murni, 2018;Saputri & Mampouw, 2018). Pecahan banyak digunakan sebagai dasar memperoleh solusi pada materi matematika lainnya seperti menghitung persentase, perbandingan senilai dan berbalik nilai, menghitung peluang suatu kejadian dan banyak lagi.…”

Pecahan penting untuk dipelajari dan dikuasai siswa karena merupakan materi esensial dalam matematika dan kehidupan sehari-hari. Namun pada kenyataannya siswa masih mengalami kesulitan dalam mempelajari pecahan. Penelitian ini bertujuan untuk menganalisis kesulitan siswa dalam mempelajari pecahan berdasarkan langkah Polya dan mendeskripsikan faktor-faktor penyebab kesulitan tersebut. Penelitian ini merupakan penelitian kualitatif dengan metode deskriptif. Subjek penelitian sebanyak 20 orang siswa kelas III salah satu MI di Kabupaten Bandung. Teknik pengumpulan data yang digunakan dalam penelitian ini adalah tes tertulis dan wawancara. Analisis data dilakukan dengan tiga langkah yaitu reduksi data, penyajian data dan penarikan kesimpulan. Hasil penelitian menunjukkan kesulitan pada: langkah memahami masalah yaitu siswa tidak dapat mengidentifikasi unsur yang diketahui dan ditanyakan pada soal; langkah merencanakan penyelesaian yaitu siswa tidak bisa membuat model matematika yang berkaitan dengan lambang pecahan; langkah melaksanakan rencana penyelesaian yaitu siswa tidak dapat merinci langkah-langkah penyelesaian yang harus digunakan untuk menyelesaikan soal; dan terakhir langkah memeriksa kembali kebenaran solusi yang diperoleh yaitu siswa tidak bisa memeriksa kembali kebenaran jawaban yang telah diperoleh. Secara keseluruhan pendekatan pembelajaran dan bahan ajar yang digunakan dianggap paling berpengaruh dalam masalah kesulitan siswa mempelajari pecahan ini. Analisis kesulitan ini dapat digunakan oleh guru untuk membuat rencana pembelajaran dengan memperhatikan langkah Polya tersebut.
