The low ability to think creatively and mathematical adaptive reasoning among students requires an innovative effort in learning. That can be create a learning atmosphere and provide space for students to develop these abilities. This development research uses a modification of the Borg and Gall model and refers to the instructional design model of Dick and Carrey. The aimed of this study, were producing Creative Problem Solving mathematical instructutional package with valid, practice and has a potential effect in increasing adaptive reasoning abilities and creative thinking abilities of students in mathematics. The research subjects were 48 second semester students of Chemical Engineering department at Politeknik Negeri Sriwijaya. The instruments used in data collection were expert validation sheets, questionnaires and test of adaptive reasoning ability and tests of creative thinking ability in mathematics. Data analysis was used to see the quality of the instructional package developed which consisted of validity and practicality, as well as the potential effects of the use of the instructional package which was seen from how much different the ability to think creatively and adaptive reasoning students' in solving mathematical problems at the pretest and posttest. The results of the development have produced instructional package based creative problem solving products that have met validity and practical criteria, and have potential effects in improving creative thinking abilities and adaptive reasoning abilities.

One reason is that the process of learning mathematics related to geometry is not yet optimal, it is the difficulty of the teacher to visualize abstract geometrical objects. Geogebra software can be used as a tool to construct, demonstrate or visualize abstract problems in learning geometry material. The problem faced by partners in implementing the geometry learning process by using Geogebra's assistance as a learning medium is the low knowledge of teachers in the use of Geogebra software and the low skills of teachers in using Geogebra software in learning geometry material. In an effort to overcome partner problems, the solution offered was to provide training and assistance to the Geogebra application to junior high school mathematics teachers in Banyuasin III to assist them in the process of learning mathematics. This activity includes theory, practice, and exercises given to participants so that skilled participants use Geogebra. This activity has succeeded in increasing teacher skills in knowledge and skills using Geogebra software for Mathematics learning. Participants understand the use of this software and are also skilled at using it for learning geometry material. This activity has also produced several instructional materials for Geogebra software assisted geometry materials.

Matematika merupakan pengetahuan dasar yang harus dikuasai dan dipahami, penguasaan matematika haruslah kuat sebagai dasar untuk menciptakan dan mengembangkan teknologi. Penelitian ini bertujuan untuk merancang prototype multimedia interaktif pada bangun ruang sisi lengkung yang valid dan praktis. Subjek penelitian ini yaitu siswa kelas VI SDIT Salsabila Palembang. Pelaksanaan penelitian dilakukan pada semester genap tahun ajaran 2021/2022. Proses pengembangan multimedia interaktif dimulai dari tahap preliminary dan tahap prototyping. Multimedia interaktif  dikembangkan pada tahap preliminary yaitu persiapan konsep yang belum dikuasai siswa, perencanaan atas dasar konsep yang masih belum dikuasai siswa, menentukan standar kompetensi, kompetensi dasar, indikator, silabus, RPP, menentukan unsur-unsur bahan ajar, mengumpulkan materi, menyusun draft bahan untuk membuat multimedia interaktif,  uji  one  to  one  dan  expert  review.  Dari  perancangan  prototype  ini dihasilkan prototype multimedia interaktif volume bangun ruang sisi lengkung untuk siswa kelas VI Sekolah Dasar yang valid dan praktis untuk meningkatkan hasil belajar siswa.
