This study aims to determine the implementation of Arabic learning using the Gallery of Learning strategy and is there an increase in student learning outcomes after the Gallery of Learning learning strategy is applied. This research model uses a quasi-experimental design model (Quasi Experiment) with test techniques (pre-test and post-test), observation, interviews, and documentation. Data analysis to test the hypothesis proposed using the "t" test through the SPSS 16.0 program as well as the validity test, reliability test, normality test, and homogeneity test. The analysis shows that the implementation of Arabic learning begins with the teacher explaining the material to be learned, then students are divided into 8 groups. The teacher explains the task of the group to discuss the material that has been determined and write the results on paper and put on top of the sponati and make a gallery. Then each group shares an assignment to tour the gallery to find out other material and maintain the gallery to explain the contents of the material to students who visit the gallery. The end of the activity is a reflection and conclusions together on what has been learned. After the implementation of the strategy, it was found that there was no significant increase in student learning outcomes using the Gallery of Learning learning strategy in class XI IPA 1 MAN 4 Sleman. Based on the results of the "t" test, the value of Sig. (2-tailed) = 0.195> 0.025, then on the basis of Independent Sample t-Test decision making, it is evident that there is a difference in influence between the average experimental group and the control group. However, it is not significant. The results of this analysis can be concluded that the Gallery of Learning learning strategy cannot significantly improve student learning outcomes in Arabic subjects in class XI IPA MAN 4 Sleman. Abstrak Penelitian ini bertujuan untuk mengetahui pelaksanaan pembelajaran bahasa Arab menggunakan strategi pembelajaran Gallery Of Learning dan adakah peningkatan hasil belajar peserta didik setelah diterapkan strategi pembelajaran Gallery Of Learning.

Ratio Reduction

Proses perpindahan cairan darah pasien menuju dialiser ditentukan oleh kecepatan aliran darah. Kecepatan aliran darah (Quick of Blood/Qb) adalah jumlah darah yang dapat dialirkan dalam satuan waktu menit (mL/menit). Semakin banyak darah yang dapat dialirkan menuju dialiser dalam permenitnya maka semakin banyak zat-zat toksik dan cairan yang berlebih dapat dikeluarkan dari tubuh.Pengaturan Qb yang tepat dan sesuai dengan kondisi pasien sangat penting diperhatikan agar tercapai efisiensi proses hemodialisis. Berdasarkan studi pendahuluan, banyak ditemukan pasien hemodialisis yang menjalani hemodialisis lebih dari 4-5 jam akibat kelebihan cairan dan urea ratio reduction (URR) berlebih di dalam darah.Tujuan penelitian ini, ingin menganalisis pengaruh penentuan Quick of Blood (Qb) terhadap keberhasilan Ureum Reduction Ratio (URR) dengan Lamanya Hemodialisis di Murni Teguh Memorial Hospital. Jenis penelitian ini adalah penelitian kuantitatif dengan metode Quasi-Experimental Study dengan desain penelitian pre test-post test. Tehnik pengambilan sampel adalah total sampling sebanyak 160 pasien hemodialisa. Sebelum (pre-test) dan sebuah (post-test), pemberian intervensi, sebelum melakukan uji statistik, peneliti melakukan uji normalitas dengan metode analisis secara komputerisasi menggunakan kolmorogov-smirnovtest dengan nilai kemaknaan (p>0,05) sehingga peneliti menggunakan uji statistik adalah one sample t-test. Hasil penelitian ini akan menjadi standar rumah sakit dalam penentuan quick of blood (Qb) sehingga lamanya hemodialisis tidak melebihi dari waktu yang ditentukan dan biaya operasional selama hemodialisis lebih efektif.

The aim of this small-scale study is to investigate the effect of indirect written feedback (coded and un-coded correction along with revisions) among ESL learners in Pakistani University and learners&rsquo; written accuracy in three types of errors (i.e., articles, past simple tense, and prepositions). In this quasi-experimental study, 50 students are randomly assigned into two groups. At initial level, teachers provide indirect written feedback (e.g., underlining, circling or error codes are provided for three types of errors) to the first group, and no feedback is provided to the second group. The participants&rsquo; written work is assessed in three phases: pre-test writing, an immediate post-test writing and delayed post-test piece of writing. Findings from an independent sample t-test demonstrate that the students receiving indirect written feedback followed by revisions perform better on new writing as compared to those who receiving no feedback at all. Findings conclude that Indirect written feedback is significant in minimizing the errors of one out of three linguistic forms in subsequent writing. Further, results suggest that indirect written feedback can help learners become more aware of their errors, reduce some of them, and so become more self-reliant.
