The low learning outcomes of students on geometry may be due to the unavailability of GeoGebra software assisted learning modules. This research aims to investigate the effectiveness of a GeoGebra software assisted learning module on the theory of flat-faced 3D shapes. This study consists of three phases, which are preliminary research, prototyping phase, and assessment phase. The test subjects are the students of a junior high school in Aceh Selatan. The research instruments cover student activity sheets, formative test sheets, student response questionnaires, and observer response questionnaires.  The results show that the learning module satisfies the effectiveness criteria. These results are supported by very good student activities, improvement in students’ score of formative test, and positive responses of the students and teachers on the learning module.

<p style="text-align: justify;">Considering the low achievement of Indonesian students in international studies (PISA), which measures Higher-Order Thinking Skill (HOTS) in solving the problem, improving the quality of mathematics learning in Indonesia is very important. The purpose of this research was conducted to explore the variations in students’ learning strategies and students’ Self–Regulated Learning (SRL) in solving mathematical HOT problems. The study employed a mixed-method, namely quantitative and qualitative methods were applied through five tests and seven interviews for over eight weeks. Two types of instruments were employed in this study, and they include tests and interviews. At the initial stage, we randomly selected 30 students from all those in grade 10 (Senior High School ), after which 12 were chosen purposively after the pre-test for an interview, having satisfied all complete group, middle group, and lower group. All of them were treated using metacognitive questions. Data analysis techniques used were percentage, data reduction, presentation, and conclusion. The quantitative results showed the students could generally use orientation, organization, and elaboration learning strategies as observed with 68.3%, 60%, and 56.7% for complete, middle, and lower groups. Moreover, the students were also observed to have conducted three cognitive processes in selecting the rules for solving the mathematical HOT problem, namely using models and drawing, written texts, and combining both. Furthermore, their final solution failures were affected by their misconceptions and errors in creating the mathematical model. The interview results on designing the learning procedures, monitoring the progress, and evaluating the outcomes, show that the students’ SRL level is good for complete (89.3%), middle (75%), and lower groups (60.7%).</p>

Pendidikan tinggi sebagai bagian dari sistem pendidikan nasional memiliki peran strategis dalam mencerdaskan kehidupan bangsa dan memajukan ilmu pengetahuan serta teknologi dengan memperhatikan dan menerapkan nilai humaniora serta pembudayaan dan pemberdayaan bangsa Indonesia yang berkelanjutan. Oleh sebab itu peningkatan mutu pendidikan di perguruan tinggi merupakan sesuatu yang tidak bisa diabaikan dan mendesak untuk segera dilakukan dengan jalan merubah subsistem yang sesuai dengan prinsip-prinsip tata kelola perguruan tinggi yang baik, GuG (Good University Governance). Tujuan utama penelitian ini adalah untuk mengkaji pengaruh profil kepemimpinan PTS yaitu kompetensi individu, gaya kepemimpinan demokratis, lingkungan yang sinergis dan komitmen pimpinan PT terhadap tata kelola pengembangan Perguruan Tinggi Swasta di Aceh. Penelitian ini menggabungkan dua metode penelitian yaitu penelitian kualitatif dan penelitian kuantitatif dengan menggunakan teknik wawancara, kuisioner dan survey. Subyek sampel penelitian ini para Rector dan Pembantu Rector Perguruan Tinggi Swasta (PTS) di Provinsi Aceh. Pada Studi awal penelitian ini, subjek sampelnya berjumlah 10 pimpinan, terdiri dari dua Universitas, dua Sekolah Tinggi dan satu Akademi. Instrumen yang digunakan adalah borang penilaian Pimpinan Perguruan Tinggi, serta instrument penelitian Kinerja Perguruan Tinggi Swasta (PTS) berdasarkan prinsip-prinsip GuG. Semua instrument penelitian dan borang penilaian melalui tahapan validasi dan reliabilitas. Hasil temuan dalam studi awal ini adalah tingkat keterpakaian borang sekitar 94%, dan pengaruh Profil kepemimpinan PTS terhadap Kinerja PTS bidang akademik sekitar 59,3% dan bidang non akademik sekitar 59,1%.
