AbstrakTujuan penelitian ini adalah untuk menghasilkan perangkat pembelajaran bercirikan Active Knowledge Sharing dengan pendekatan saintifik dalam upaya meningkatkan pengetahuan, kemampuanpemecahan masalah, dan sikap terhadap matematika siswa SMP Kelas VIII Semester 2 yang valid, praktis, dan efektif. Jenis penelitian ini adalah penelitian pengembangan (Development Research). Penelitian ini mengembangkan perangkat pembelajaran yang meliputi: silabus; Rencana Pelaksanaan Pembelajaran (RPP); dan Lembar Kegiatan Siswa (LKS) dengan menggunakan model pengembangan 4-D yang dikembangkan oleh Thiagarajan, Semmel, dan Semmel. Hasil validasi menunjukkan perangkat yang dikembangkan layak digunakan dengan kategori sangat baik. Hasil uji coba menunjukkan bahwa perangkat yang dikembangkan praktis dan efektif. Ketuntasan belajar secara klasikal sudah mencapai kriteria minimal 80% yaitu untuk tes pengetahuan mencapai 97,2%, sedangkan tes pemecahan masalah mencapai 95,4%. Berdasarkan angket sikap terhadap matematika, 98,1% siswa menunjukkan peningkatan skor sikap terhadap matematika, dan 94,4% siswa menunjukkan sikap terhadap matematika dengan kategori minimal baik.

This was a research and developmental study. The learning kit developed consist of: syllabus; lesson plans; and students worksheets. This developmental study refers to the model 4-D suggested by Thiangarajan, Semmel & Semmel. The results of the validation shows that the kit developed was valid with "very good" category. The experimental results show that the kit developed was practical and effective. Classical learning completeness reached at least 80% criterion for the test of knowledge 97.2%, while the troubleshooting tests reached 95.4%. Based on the questionnaire attitudes towards mathematics, 98.1% of students show increased scores for attitudes toward mathematics and 94.4% of students show attitudes towards mathematics with minimum category of good.
Principal leadership was a determining factor in the education process in MI Muhammadiyah Special Program Kartasura. Principal leadership emphasized the formation of student character and not on student grades. The purpose of this study was to describe the leadership style applied and the role of principals as leaders in building high-quality school. This type of research was qualitative research. The research design used was phenomenology. Research used primary data in the form of interviews and observations and used secondary data in the form of documents obtained from school. The data analysis used was an interactive model analysis with source triangulation and methods. The results of this study were: First. Principal leadership had a democratic-monarchic leadership style. This was based on the system that applied in the process of determining policies and decision-making processes carried out jointly. Second, the role of the principal included several aspects that had been carried out, namely: as an educator, as a manager, as an administrator, as a supervisor, as a leader, as an innovator, as a very good motivator. The principal could be an example in carrying out their duties. Therefore, the type and character of the leader must be observed and assessed properly.

The aim of this research is to produce Flipbook-based Electronic Teaching Materials based on problem solving skills with CTL Approach in Elementary School Class V that was valid, practical, and effective. The type of research is development research. This research developed Flipbook-assisted Electronic Teaching Materials on the mathematics learning of Class V Elementary School by using the 4-D, the model was developed by Thiagarajan, Semmel, and Semmel. The validation result indicated that The Electronic Teaching Materials developed was feasible to be used with good minimum category. The results of the field trial showed that The Electronic Teaching Material developed was practical and effective. The practicality was assessed by the students and reached 62.5 with good category. The practicality assessed by the teacher reached 25.5 (very good) on material aspect; 13.5 (very good) on the language aspect; and 35 (very good) on aspects of interest and influence. The student's problem solving skill on posttest is 92.9%. There was an increase in scores obtained by the students in steps that were understanding the problem, planning, implementing the plan, and looking back. The percentage of student attitudes toward mathematics with very good category increased 42,8%, the percentage of student attitudes toward mathematics with good category increased 31,25%.
