تطوير المواد الدراسية في تعليم مهارة الكتاب في برنامج الخاض لتعليم اللغة العربية في جامعة مولانا مالك ابراهم الإسلامية الحكومية مالانج

ABSTRAK Perkembangan Universitas Islam Negeri Maulana Malik Ibrahim Malang sebagai salah satu Perguruan Tinggi Islam yang berkembang pesat membutuhkan terobosan- terobosan yang handal. Salah satu hal penting yang tidak bisa dipisahkan adalah peranan penting dari PKPBA (Program Khusus Pengembangan Bahasa Arab). PKPBA sebagai sebuah unit pengembangan bahasa, telah berperan penting dalam membantu meningkatkan kemampuan berbahasa mahasiswa khususnya bahasa arab. Banyak dari mahasiswa yang pertama kali masuk PKPBA belum mengetahui bahasa Arab. Namun setelah belajar di PKPBA mereka mampu mengenal ilmu bahasa arab. Namun, tidak hanya berhenti pada mengetahui bahasa arab saja, program ini juga berupaya agar semua mahasiswa mampu untuk menguasai salah satu dari 4 ketrampilan bahasa yakni ketrampilan menulis. Tujuan dari peneliyian ini adalah untuk melengkapi proses pengembangan penyusunan materi ajar menulis dan mengetahui ke-efektifan materi yang dikembangkan. Penelitian ini menggunakan prosedur eksperimen dimana peneliti mendisain Pre-test dan Postest terhadap dua kelompok yakni kelompok eksperimen dan kelompok kontrol. Hasil penelitian ini adalah bahwa pembelajaran ketrampilan menulis dengan menggunakan buku ajar lebih efektif dari pada tanpa menggunakan buku ajar. Dengan indikasi bahwa t-test kelas eksperimen (J3) lebih efektif dengan indikasi bahwa t-test kelas kontrol adalah 3,4. dimana hasil ini lebih besar dari pada tingkat t-table 5% 2,059 dan tingkat 1% 2,787. Dari hasil ini menunjukan bahwa pengajaran menulis bahasa Arab efektif dengan menggunakan materi ajar yang telah disusun oleh peneliti. Hasil penelitian ini adalah: (1) Penyusunan materi ajar untuk PKPBA dimulai dengan membatasi tujuan pengajaran, kemudian menentukan pembagian materi sesuai dengan jumlah hari yang digunakan untuk pembelajaran dalam satu minggu. (2) Pembelajaran menulis bahasa Arab dengan menggunakan Materi ajar ini dinyatakan efektif. Dari hasil yang disebutkan diatas, sudah semestinya materi pengajaran menulis bahasa Arab dapat dimanfaatkan dengan benar dalam proses pengajaran, selain itu penulis berharap agar penelitian ini menjadi referensi untuk penelitian lanjutan yang berhubungan dengan penelitian ini sehingga dapat dikembangkan ke dalam desain materi ajar menulis untuk tingkat selanjutnya. ABSTRACT The expansion of State Islamic University Maulana Malik Ibrahim need some powerful breakthrough. One of the important things is the role of Intensive Arabic Program as unit for improving Arabic, have played an important for helping Arabic language improvement. Most of the students when the first time they enter to this Program, they haven’t yet Arabic knowledge. But after studying in this program for several months they could understand about Arabic. But is not enough in knowing the Arabic only, but this program also try to make all students are mastering one of these four skills, that is writing skill. This research aims at designing process of writing teaching material and finding out the effectiveness of writing teaching material using in Intensive Arabic Program of State Islamic University of Maulana Malik Ibrahim Malang. This research uses the experimental method that the researcher design pre-test and post-test for both groups (Experiment and Control group). This research reach the degree of t-test 3,4 this biggest than t-table at the level of 5% (2,059) and at the level 1% (2,787). This indicates that the use of writing Teaching Material in Arabic for improving writing skill is effective. And the result of this research are obtained bellow: (1) Preparing this teaching material process started by determining the goals, finding out the learning material based on the days in a week which used for teaching (2) The use of writing Teaching Material in Arabic for improving writing skill is effective. Based on these results, teaching material must be used as good as possible in teaching process. Besides, the researcher hopes that the research becomes the reference for further researchers which have a relation with this chapter and could be developed to other teaching material for advance grade

Recurrent somatic mutations in POLR2A define a distinct subset of meningiomas

RNA polymerase II mediates the transcription of all protein-coding genes in eukaryotic cells, a process that is fundamental to life. Genomic mutations altering this enzyme have not previously been linked to any pathology in humans, which is a testament to its indispensable role in cell biology. On the basis of a combination of next-generation genomic analyses of 775 meningiomas, we report that recurrent somatic p.Gln403Lys or p.Leu438_His439del mutations in POLR2A, which encodes the catalytic subunit of RNA polymerase II (ref. 1), hijack this essential enzyme and drive neoplasia. POLR2A mutant tumors show dysregulation of key meningeal identity genes including WNT6 and ZIC1/ZIC4. In addition to mutations in POLR2A, NF2, SMARCB1, TRAF7, KLF4, AKT1, PIK3CA, and SMO4 we also report somatic mutations in AKT3, PIK3R1, PRKAR1A, and SUFU in meningiomas. Our results identify a role for essential transcriptional machinery in driving tumorigenesis and define mutually exclusive meningioma subgroups with distinct clinical and pathological features

Somatic POLE

BACKGROUND: Malignant high-grade gliomas (HGGs), including the most aggressive form, glioblastoma multiforme, show significant clinical and genomic heterogeneity. Despite recent advances, the overall survival of HGGs and their response to treatment remain poor. In order to gain further insight into disease pathophysiology by correlating genomic landscape with clinical behavior, thereby identifying distinct HGG molecular subgroups associated with improved prognosis, we performed a comprehensive genomic analysis. METHODS: We analyzed and compared 720 exome-sequenced gliomas (136 from Yale, 584 from The Cancer Genome Atlas) based on their genomic, histological, and clinical features. RESULTS: We identified a subgroup of HGGs (6 total, 4 adults and 2 children) that harbored a statistically significantly increased number of somatic mutations (mean = 9257.3 vs 76.2, P = .002). All of these “ultramutated” tumors harbored somatic mutations in the exonuclease domain of the polymerase epsilon gene (POLE), displaying a distinctive genetic profile, characterized by genomic stability and increased C-to-A transversions. Histologically, they all harbored multinucleated giant or bizarre cells, some with predominant infiltrating immune cells. One adult and both pediatric patients carried homozygous germline mutations in the mutS homolog 6 (MSH6) gene. In adults, POLE mutations were observed in patients younger than 40 years and were associated with a longer progression-free survival. CONCLUSIONS: We identified a genomically, histologically, and clinically distinct subgroup of HGGs that harbored somatic POLE mutations and carried an improved prognosis. Identification of distinctive molecular and pathological HGG phenotypes has implications not only for improved classification but also for potential targeted treatments
