Penelitian ini bertujuan untuk menghasilkan produk berupa perangkat pembelajaran bangun ruang SMP dengan pendekatan problem-based learning yang valid, praktis, dan efektif dilihat dari pencapaian kompetensi dasar, kemampuan berpikir kritis, dan sikap terhadap matematika. Jenis penelitian ini merupakan penelitian pengembangan model 4D yang meliputi tahap pendefinisian, perancangan, pengembangan, dan tahap disseminasi. Hasil penelitian berupa perangkat pembelajaran bangun ruang yang terdiri atas silabus, RPP, LKS, dan instrumen evaluasi berupa tes pencapaian kompetensi dasar dan kemampuan berpikir kritis yang valid, praktis, dan efektif. Kevalidan perangkat mencapai kategori sangat baik ditinjau dari penilaian para ahli. Kepraktisan perangkat mencapai kategori sangat baik ditinjau dari penilaian guru, penilaian peserta didik, dan observasi keterlaksanaan pembelajaran. Aspek keefektifan dipenuhi dari tercapainya minimal 75% peserta didik lulus KKM ditinjau dari pencapaian kompetensi dasar dan berpikir kritis, serta lebih dari 80% peserta didik mempunyai sikap terhadap matematika dalam kategori tinggi. Dari kegiatan ekperimen diperoleh bahwa perangkat yang dikembangkan lebih efektif daripada perangkat pembelajaran konvensional ditinjau dari pencapaian kompetensi dasar, berpikir kritis, dan sikap terhadap matematika.

This study was and development study using the 4D development model that included defining, designing, developing, and disseminating phase. This study produced valid, practical, and effective space learning kits that consisted of syllabus, lesson plans, students’ worksheets, and assessment tests that included test of basic competence achievement and critical thinking test. Kits validity gets very good category from expert assessment. Kits practically gets very good category from teachers assessment, students assessment, and observation of learning implementation. The aspect of effectiveness was seen from achievement minimal 75% of the student pass the minimum score for achievement of basic competence and critical thinking skill, and more than 80% of student have attitude toward mathematics in high category. The result of experiment activity shows that the developed learning kits more effective than conventional learning kits based on achievement of basic competence, critical thinking, and attitude toward mathematics.

The Covid-19 pandemic has had an impact on change in various fields, including in higher education. This study provides an overview of the survey result of the experience of 14 lecturers of the Mathematics Education Study Program at the University of Sanata Dharma towards learning in responding to Pandemic Covid-19. The intended experience includes the strategies and technologies used in learning, learning success in terms of the achievement of objectives and student involvement, and planning for future learning. The results showed that (1) all lecturers conducted distance learning by utilizing various kinds of technology both synchronous and asynchronous as a form of learning adjustment to face a pandemic. (2) Although there was an adjustment in learning, most mathematics learning can run according to learning achievements. (3) The Mathematics Education lecturer will implement an improvement in learning that must be carried out online. The improvement is in the form of preparation and planning of learning, the use of more varied technologies, the use of more innovative methods of delivering material, adjustment of learning in terms of learning achievement and evaluation while still focusing on developing student experience.
Problem-based learning was an alternative learning model that can be implemented in a learning based on Reflective Pedagogy approach. Reflective Pedagogy not only prioritized knowledge aspect but also attitude aspect. This research was aimed to 1) describe the implementation of PBL using cycle of Reflective Pedagogy on Advanced Statistics learning and to 2) describe its influenced based on critical attitude, enthusiasm, and caring for others. The subject of this research was Psychology Student of class A. Data collection was gathered from the questionnaire and the results of student reflection. The result showed that the PBL phases could be well implemented in Advanced Statistics learning using Reflective Pedagogy. From the analysis was concluded that PBL gave influenced in good enough category based on critical attitude, enthusiasm, and caring for others.DOI: https://doi.org/10.24071/ijiet.2018.020102
