Administrators’ Role in management of ICT integration at secondary school in Indonesia
(2014-02-03) Achmad, Said Suhil
The aim of this paper is to identify the concept of administrators’ role in the integration management of ICT at secondary schools in Indonesia, which is whether the administrators’ role in planning, organizing, leadership and controling the ICT integration at schools can run effectively and efficiently. The function of ICT in education is as a source of learning, learning aids, learning facilities, Standard competence, administration system, decision support, and infrastructure which can fix the effectiveness of school management and improve the academic achievement of students and teaching staff. The absence of an ICT good design will not provide optimum benefit, even it is possible that it will be a barrier educational activity. A number of studies show that a relationship between effective management and quality schools, or in other words, management, can make the difference between an effective and efficient school. Management functions that must be performed by the administrator are planning, organizing, leadership and controlling, so that the integration of ICT in schools can actually achieve the goals that have been defined together. Schoolbased school management proved more effective because school administrators take over educational responsibilities from the national govemment, regional and local strategic approach which integrate several different aspects of management to set and achieve their own educational institutions. Furthermore, the role of administrators in the information technology integration is very important especially in Indonesia which is still in the replicate level, new settings, and adjustment, like the use of technology into learning

(2014-01-27) Ras, Fakhri
Penelitian yang berjudul “Analisis Paradigma Pengajaran Reading di SMU Negeri propinsi Riau” bertujuan untuk menemukan kerangka kerja pengajaran efektif dan efisien atas dasar kelebihan (strengths) dan kelemahan (weakness) para siswa. Dengun tercapainya tujuan tersebut, para guru dapat menghemat enegri di kelas (sebagai fasilitator dan komunikator) dalam memperkuat pemahaman siswa terhadap bacaan yang sedang mereka pelajari. Subjek penelitian adalah para siswa SMU Negeri Provinsi Riau yang terbagi kepada dua wilayah – daratan dan lautan namun mengingat sulitnya lokasi untuk dijangkau penelitian dilakukan dua wilayah daratan diwakili oleh siswa SMU Negeri Kotamadya Pekanbaru, Kabupaten Kampar, dan Kabupaten Indragiri Hulu. Dalam penelitian ini akan diambil satu SMU di kotamadya Pekanbaru (SMUN 8), dua lagi di kabupaten Kampar (SMUN 1 Bangkinang) dan di Kabupaten Ingragiri Hulu (SMAN 1 Rengat). Siswanya dibatasi padakelas dua saja mengingat masih besarnya pengaruh belajar di SLTP pada kelas I dan sibuknya para siswa mempersiapkan diri untuk menghadapi EBTANAS pada siswa kelas III. Bentuk kelompok target dan kelompok kontrol, data dikumpulkan dalam satu rentangan waktu penelitian yakni 10 bulan yang dimulai dengan pretest dan post-test (kedua-dua test tersebut adalah rancangan peneliti). Untuk mendapatkan test yang valid dan reliable, test yang sudah dirancang diujicoba (trying out) di SMU Negeri di luar kota terzebut diatas tetapi masih dalam wilayah Provinsi Riau. Hasil ujicoba tersebut akan diadakan analisis setiap pertanyaan tentang ambang batas tingkat kesulitan atau kemudahan yakni antara 26% sampai 75%. Untuk kelompok target, setiap dua kali kegiatan belajar bacaan akan diberikan assessment untuk menentukan posisi subjek penelitian dengan test yang sesuai pada kegiatan berikutnya. Demikian pula untuk setiap dua kali kegiatan berikutnya sampai dengan dilakukannya post-test. “The Fry Readability Estimate” dipakai menentukan setiap teks bacaan yang akan diapaki dalam kegiatan penelitian (pre-test bahan ajar dan post-test). Sumber bahan bacaannya adalah buku teks yang berlaku, buatan peneliti sendiri, dan majalah dan Koran berbahasa Inggris yang relevan. Sedangkan untuk kelompok control, bahan bacaan yang dipakai adalah seluruh bacaan yang sedang dipakai di SMU tersebut. Data yang terkumpul dari kedua kelompok tersebut akan dianalisis kelebihan dan kekurangan subjek penelitian dalam hal pemahaman elemen-elemen pendukung reading yakni penguasaan tata bahasa, kosakata, dan kompleksitas ide-ide bacaan. Selanjutnya hasil kegiatan dari hasil kedua kelompok tersebut akan dibandingkan untuk menentukan apakah ada perbedaan hasil dari dua jenis tindakan pengajaran tersebut dengan cara/comparing the two means (lihat Evelyn harch dan Hossein Farhady : 1982).
