Penelitian ini bertujuan untuk mengembangan media TaKeru sebagai media pembelajaran yang efektif untuk diterapkan kepada Subjek penelitian yaitu siswa SMP kelas IX. Penelitian ini menggunakan metode penelitian Research and Development (R and D), dan prosedur pengembangan ADDIE (Analysis, Design, Development, and Evaluation). Teknik analisis data yang digunakan adalah teknik analisis data deskriptif yaitu dengan mendeskripsikan kevalidan, kepraktisan, dan keefektifan media TaKeru dengan menggunakan Uji-t. Instrumen yang digunakan dalam penelitian ini adalah lembar validasi media, lembar tes, dan angket respons siswa yang akan diberikan pada delapan siswa. Hasil penelitian menunjukkan bahwa sebesar 80% partisipan menunjukkan respons positif, dan hasil belajar siswa mengalami peningkatan yang ditunjukkan oleh nilai t hitung = 5,635 > t tabel = 2,365, dengan taraf signifikansi 5%. Berdasarkan peningkatan hasil belajar serta respons positif dari siswa, Media TaKeru sebagai media pembelajaran berbasis literasi matematika valid, praktis, dan efektif diterapkan untuk mengajarkan materi bangun ruang sisi lengkung (tabung dan kerucut).

Kedua konsep tersebut perlu diimplementasikan dalam pembelajaran, sehingga para guru perlu dibekali keterampilan merancang pembelajaran tersebut sekaligus memahami konsep masalah, pemecahan dan pengajuan masalah. Untuk mencapai tujuan tersebut, diperlukan program pelatihan guru untuk memantapkan pemahaman guru tentang pemahaman konten dan desain pembelajaran berbasis pengajuan dan pemecahan masalah matematika. Guru yang terlibat adalah 22 guru SMP yang ditugaskan oleh Dinas Pendidikan Kabupaten Magetan. Metode pelaksanaan terdiri dari tahap persiapan dengan melakukan koordinasi dengan mitra dan tim pelatih untuk merancang instrumen dan materi pelatihan. Tahap pelaksanaan terdiri dari kegiatan tatap muka dan kegiatan mandiri dengan diawali pemberian angket untuk analisis awal (pra-tes), pemberian materi pelatihan, praktik penyusunan soal, presentasi, dan kegiatan mandiri merancang perangkat pembelajaran. Tahap selanjutnya evaluasi dan tindak lanjut dilakukan dengan pemberian angket akhir pelatihan (pasca-tes) dan angket refleksi kegiatan. Hasil pelatihan menunjukkan 81,8% guru mampu memahami konsep dan mendesain pembelajaran berbasis pengajuan dan pemecahan masalah. Hasil evaluasi kegiatan guru menunjukkan 95,45% guru cenderung mengatakan baik dan menyarankan kegiatan perlu ditindaklanjuti.

However, many teachers could not effectively arrange and utilize it so that the learning objectives stated might not be reached. This study aims to generate a PISA-based student worksheet on valid and practical content and expose the effect on the ability to understand students' mathematical concepts. Using development research of a preliminary research, development phase, and assessment, the worksheet is composed. Besides, a test is used to determine the effectiveness of worksheets and another test is also to find out the effect of worksheets that have been made on the ability to understand mathematical concepts. As a result, this study has produced a valid and practical PISA-based student worksheet. The thing that is distinctive of this worksheet is that the question contains Sharing Task and Jumping Task. The result also shows that the worksheet could improve student understanding of a mathematical concept.

A mathematical learning following an inquiry-based learning approach and integrating mathematical tools was developed in this study. Students constructed original solutions about trigonometry ratio by using a clinometer and a meter as mathematical tools in allowing creative thinking. The product was designed through ADDIE methodology and applied to two classes in a Senior High School. A pre-test and post-test design measured cognitive knowledge as creative thinking variable. The result showed that this product with using mathematical tools was feasible and successful in enhancing students’ creative thinking. Inquiry-based learning was developed by involving three main components: providing students with a contextual mathematical problem-solving activity; involving student in an open-ended investigation with using a clinometer and a meter as mathematical tools to promote their creative thinking in creating or...

This research uses research procedure and development 4D equipment model suggested by Thiagarajan, Semmel and Semmel. This model consist of 4 steps, they are Define, Design, Develop and Desseminate, however in this research and development, the activity is done only in to the development steps. The result of expert testing toward the design of come into being thes aspect of LKPD includes in the suitable criteria with the precentage 79,66% and the result of the test in the material content of LKPD also includes suitable criteria with the precentage 81,22% and the last is the test of reading level LKPD by the students got very good criteria with presentage 80,3%. Based on the result from expert testing and student testing, those show that LKPD scientific approach base has been developed properly to be used and ready to serve as one of the references in Biology learning material scientific approach based in Fungi. Kata Kunci: lembar kegiatan peserta didik (LKPD), pendekatan saintifik.

These study aimed to develop TaKeru media as an effective learning medium to be applied as research subjects to class IX junior high school students. This study used Research and Development (R and D) methods, and ADDIE (Analysis, Design, Development, and Evaluation) development procedures. The data analysis technique used in this study was descriptive data analysis technique, which described the validity, practicality, and effectiveness of the TaKeru media using t-test. The instrumens used in this study were media validation sheets, test sheets, and student response questionnaires for eight students. The results showed that 80% of the participants showed a positive response, and student learning outcomes also increased, indicated by the value of t count = 5.635> t table = 2.365, with a significance l...
