Latar Belakang : Kadar kolesterol LDL yang tinggi dan HDL yang rendah berkaitan dengan penyebab utama terjadinya penyakit jantung dan pembuluh darah. Serat diketahui dapat menurunkan kadar kolesterol LDL serta meningkatkan kolesterol HDL. Nata de coco mengandung selulosa, hemiselulosa dan lignin yang memiliki efek hipokolesterolemia dalam darah.Metode : Jenis penelitian adalah true experimental dengan rancangan control group pre-test-post-test. Sebanyak 52 wanita dengan kadar kolesterol LDL ≥100 mg/dl dan HDL ≤50 mg/dl menjadi subyek dalam penelitian ini. Subyek dibagi menjadi 3 kelompok, yaitu kelompok kontrol, perlakuan 1 mendapat 160 g nata de coco/hari (serat 4.8 g) dan perlakuan 2 mendapat 320 g nata de coco/hari (serat 9.6 g). Intervensi dilakukan selama 14 hari. Metode phosphotungstic precipilation digunakan untuk menganalisis kadar HDL sementara kadar LDL dianalisis mengunakan rumus Friedewald. Darah diambil setelah subyek berpuasa selama 10 jam. Analisis statistik yang digunakan antara lain paired-samples t test, ANOVA dan Kruskal-Wallis.  Hasil : Konsumsi nata de coco sebanyak 160 g/hari dan 320 g/hari berturut-turut menurunkan kadar kolesterol LDL sebanyak 4.47% (p=0.091) dan 6.25% (p=0.044) serta meningkatkan kadar kolesterol HDL sebanyak 12.1% (p=0.001) dan 3.6% (p=0.361). Tidak terdapat perbedaan pengaruh pemberian nata de coco terhadap perubahan kadar kolesterol LDL antar kedua kelompok (p=0.863), namun terdapat pengaruh yang bermakna terhadap kolesterol HDL antar kedua kelompok (p=0.043). Sedangkan pada kelompok kontrol terjadi peningkatan kadar kolesterol LDL sebebesar 2.54% (p=0.005) dan penurunan kadar kolesterol HDL sebesar 0,56% (p=0.570).Kesimpulan : Konsumsi nata de coco sebanyak 320 g/hari berpengaruh terhadap penurunan kadar kolesterol LDL secara bermakna sedangkan pemberian nata de coco sebanyak 160 g/hari berpengaruh terhadap peningkatan kolesterol HDL secara bermakna.Kata kunci : nata de coco; kolesterol LDL; kolesterol HDL; wanita; dislipidemia.

This study aims to investigate the effectiveness of using visual materials in teaching vocabulary to deaf students of EFL. For this purpose, 80 deaf students from a state special education vocational high school in Turkey contributed to this study. All students had first English classes in their lives and they are at the starter level of English, thus pre-test for their English proficiency was not given. The students were randomly divided into two groups to form the experimental group and the control group. 10 vocabulary items per week were taught to the students, and 50 target vocabulary items in total were taught during the whole study. To the experimental group, the vocabulary items were taught via visual materials together with the sign language. The control group was not presented with any visual items during the teaching process of the experiment, only sign language instruction was used for them. After the treatment, a vocabulary test was given to each group as an immediate post-test to measure the impact on learning. Six weeks after the immediate tests, delayed post-test was given to the groups to test long term retention. The results of the two post-tests were analyzed through Independent Samples t-test and Paired Samples t-test calculations to investigate the effectiveness of visual materials. According to the results of the study, visual materials were found to be more effective than using only the sign language that does not contain any visual items in teaching vocabulary items to deaf learners who learn English as a foreign language.

The aim of this study was to investigate the effect of a discoursal approach on Iranian intermediate EFL learners’ reading comprehension ability. A Quick Placement Test (QPT) was used to select 60 intermediate EFL learners as the participants of this study. Then, they were divided into experimental and control groups. Each group consisted of 30 learners. Prior to the treatment, the participants of both groups were given a pre-test to determine their reading comprehension levels. The experimental group was exposed to the Hymes’ model. In the control group the researcher used a traditional approach for teaching the reading skill. Then a post-test was administered to both groups. An independent samples t-test between post-tests of the study and a paired-samples t-test between the pre-test and post-test of the groups of the study were run. The results of the study indicated that applying Hymes’ model improved the learners’ reading comprehension while the traditional approach did not. ﻛﺎ ن اﻟ ﮭد ف ﻣ ن ھذه اﻟ د را ﺳﺔ ھو اﻟﺗﺣ ﻘﯾ ق ﻓ ﻲ ﺗﺄﺛﯾ ر اﻟﻧﮭ ﺞ اﻟﺗد ر ﯾﺑ ﻲ ﻋ ﻠ ﻰ ﻗد ر ة اﻟ ط ﻼ ب ا ﻹ ﯾ ر اﻧ ﯾﯾ ن ﻋ ﻠ ﻰ ﺗ ﻌﻠ م اﻟﻘ ر ا ءة واﻟ ﻛﺗﺎﺑ ﺔ ﻓﻲ اﻟﻠ ﻐﺔ ا ﻹﻧ ﺟﻠﯾ زﯾﺔ ﻛﻠ ﻐﺔ أ ﺟﻧﺑﯾﺔ. ﺗم ا ﺳﺗ ﺧدام ا ﺧﺗﺑﺎ ر ﺗ ﺣدﯾد اﻟ ﻣ ﺳﺗ و ى اﻟ ﺳرﯾ ﻊ (QPT) ( ﻟﻠﺗﺄ ﻛد ﻣ ن ﺗ ﺟﺎﻧ س ﻣﺗ ﻌﻠ ﻣ ﻲ اﻟﻠ ﻐﺔ اﻹ ﻧ ﺟﻠﯾ زﯾ ﺔ ﻛﻠ ﻐﺔ أ ﺟﻧﺑﯾ ﺔ اﻟذﯾ ن ﻛﺎﻧ وا ﻓ ﻲ ﻓ ﺻ ﻠﯾ ن د را ﺳﯾﯾ ن. ﺛم، ﺗم ﺗﻘ ﺳﯾ ﻣﮭم ﺑ ﺷﻛل ﻋﺷواﺋ ﻲ إﻟ ﻰ ﻣ ﺟﻣوﻋﺎ ت ﺗ ﺟرﯾﺑﯾ ﺔ وﻣراﻗﺑ ﺔ. ﻛل ﻣ ﺟﻣوﻋﺔ ﺗﺗﺄﻟ ف ﻣ 30 ﻣﺗ ﻌﻠ ﻣﺎ. ﻗﺑ ل اﻟ ﻌ ﻼج، ﺗم إ ﻋطﺎ ء اﻟ ﻣ ﺷﺎ رﻛﯾ ن ﻣ ن ﻛ ﻼ اﻟ ﻣ ﺟﻣوﻋﺗﯾ ن ﻗﺑ ل ا ﻻﺧﺗﺑﺎ ر ﻟﺗ ﺣدﯾد ﻣ ﺳﺗ وﯾﺎ ت اﻟ ﻔ ﮭم اﻟ ﻘ ر ا ءة ﻟ دﯾ ﮭم. ﺗ ﻌر ﺿ ت اﻟﻣ ﺟ ﻣو ﻋ ﺔ اﻟ ﺗ ﺟ ر ﯾﺑﯾ ﺔ ﻟﻧ ﻣو ذ ج اﻟ ﺗ ر اﺗﯾ ل . ﻓ ﻲ اﻟﻣ ﺟ ﻣو ﻋ ﺔ اﻟ ﺿ ﺎﺑ ط ﺔ، ا ﺳ ﺗ ﺧ دم اﻟ ﺑﺎ ﺣ ث اﻟﻣﻧ ﮭ ﺞ اﻟ ﺗﻘﻠﯾد ي ﻟﺗد ر ﯾ س ﻣﮭﺎ ر ة اﻟ ﻘ ر ا ءة. ﺛم ﺗدا ر ﺑ ﻌد ا ﻻ ﺧ ﺗﺑﺎ ر ﻟ ﻛ ﻼ اﻟ ﻔ ر ﯾﻘﯾ ن . ﺗم إ ﺟ ر ا ء ا ﺧ ﺗﺑﺎ ر ﻣ ﺳ ﺗﻘ ل ﻟ ﻌﯾﻧﺎ ت t ﺑﯾن ا ﻻ ﺧ ﺗﺑ ﺎ ر ﯾ ن اﻟﻼ ﺣ ﻘﯾ ن ﻟﻠد ر ا ﺳ ﺔ و ا ﺧ ﺗﺑﺎ ر t اﻟﻣﻘﺗ ر ن ﺑﺎﻟ ﻌﯾﻧﺎ ت ﺑﯾ ن ا ﻻ ﺧ ﺗﺑﺎ ر اﻟﻣ ﺳ ﺑ ق و ا ﻻ ﺧ ﺗﺑﺎ ر اﻟﻼ ﺣ ق ﻟ ﻣ ﺟ ﻣو ﻋ ﺎ ت اﻟد ر ا ﺳ ﺔ. أ ﺷ ﺎ ر ت ﻧﺗﺎﺋ ﺞ اﻟد ر ا ﺳ ﺔ إﻟﻰ أ ن ﺗ ط ﺑﯾ ق ﻧ ﻣو ذ ج ھ ﺎﯾ ﻣز ﻗد ﺣ ﺳ ن ﻣ ن ﻓ ﮭم اﻟ ﻘ ر ا ءة ﻟﻠﻣﺗ ﻌﻠ ﻣﯾ ن ﻓ ﻲ ﺣ ﯾ ن أ ن اﻟ ﻧ ﮭ ﺞ اﻟ ﺗﻘﻠﯾد ي ﻟ م ﯾﻔ ﻌل ذﻟ ك
