Abstract

The purpose of this study is to ascertain whether teaching vocabulary to students through Total Physical Response is effective. The 8th grade and his English teacher at Jandob Preparatory School were the case study of this paper. In collecting data, the researcher used test and interview. The tests were used to know the improvement of the vocabulary after using TPR method. Meanwhile, the interview was used to know to what extend teacher know TPR. According to tests results showed that improvement of students after using TPR from 41.6% to 74.2%andthe information obtained from the teacher's interview shown that he was unaware of TPR. The findings of the study support the idea that TPR improve students' vocabulary understanding.

Key words : Total physical response(TPR), vocabulary, students, elementary, pupils.

هدف هذه الدراسة هو التأكد مما إذا كان تدريس المفردات للطلاب من خلال الاستجابة الجسدية الكلية فعالًا. وكانت دراسة حالة الصف الثامن ومعلم اللغة الإنجليزية في مدرسة جندوبة الإعدادية هي موضوع هذه الورقة. في جمع البيانات، استخدم الباحث الاختبار والمقابلة. استخدمت الاختبارات لمعرفة تحسين المفردات بعد استخدام طريقة الاستجابة الجسدية الكلية. في حين استخدمت المقابلة لمعرفة مدى دراية المعلم بالاستجابة الجسدية الكلية. ووفقًا لنتائج الاختبارات، أظهرت تحسينًا في مستوى المفردات للطلاب بعد استخدام الاستجابة الجسدية الكلية من 41.6٪ إلى 74.2٪ ، وأظهرت معلومات المقابلة التي تم الحصول عليها من المعلم أنه غير مدرك للتقنية. تدعم نتائج الدراسة فكرة أن الاستجابة الجسدية الكلية تحسن فهم المفردات لدى الطلاب

Abstract

The research was conducted to investigate the impact of classroom interaction on English language learning different levels of education. Furthermore, the meaning of classroom interaction has been defined. In addition, some factors to create effective and interaction in classroom have mentioned. Also, some effective and remarkable strategies were presented in order to help teachers to get better performance. Moreover, some teaching methods were suggested to develop the classroom interaction skills of students. 

This study attempts to identify the use of metadiscourse (MD) in the Libyan science lectures and investigate the lecturers’ perceptions towards the use of MD. Six audio-recorded lectures from the fields of chemistry, physics, and botany were selected in this study. To analyze this collected spoken data, Hyland’s (2005) analytical framework of metadiscourse has been used. The findings showed that interactive metadiscourse was used more than interactional metadiscourse. Among all the subcategories, transitions, engagements and code glosses were the most common markers. The absence and lack of some categories were remarkable as self-mention and evidentials. The results of this study may suggest that when teaching or learning a language, metadiscourse should be given special consideration by both language instructors and students.

Melanoma is one of the fatal forms of skin cancer, and has become more common, especially among white-skinned people exposed to the sun. Early detection of melanoma is essential to increase survival rates, since its detection in an early stage can be helpful and curable. Working out the dermoscopic clinical features of melanoma is an important step for dermatologists, who need an accurate way of reaching the correct clinical diagnosis, and to ensure the right area gets the right treatment. In this paper, we present a comprehensive approach including image enhancement, segmentation of lesions and melanoma detection, to allow for early detection of malignant melanoma disease. As an image enhancement, the Gabor filter, image sharpening, Sobel filter and image inpainting methods are integrated to delete unwanted objects (noise). The lesion border segmentation is performed by combining the Particle Swarm Optimization and the Markov Random Field approaches. To be able to determine the lesions types, the K-means is applied on the segmented lesion, to separate it into homogeneous clusters, where important features are extracted, then an Artificial Neural Network is trained by representative features to classify the given lesion as melanoma or not. The whole experimental results obtained on a public database PH2 and compared with existing methods in the literature have shown that our proposed approach is accurate, robust, and efficient in the segmentation of the lesion boundary, as well as its classification.

Abstract

Dear colleagues, Asalamu Alykum

Welcome to the group of dermatologists in Libya, which hosts specialists and dermatologists and those who are involved in the training program for specialization, through which subjects related to the specialization are posted in the form of different formulas and scenarios, for example clinical patient photos or theoretical topics for discussion or the introduction of

topics of medical literature for enrichment Discussion, sharing and

exchange of experiences among fellows in the CME course

In view of the privacy of the group in terms of which medical cases are reviewed with pictures of patients, it is necessary to join those with the

real name of the doctor and do not accept the aliases and only admission to

doctors and their names the truth and we hope from the colleagues

appreciate this point. In order to protect us from individual ownership, it is

not permissible to present pictures of patients' cases except by the doctor

concerned. It should be noted that there is no room in this group for

advertising propaganda and promotional all types and keep them as a

scientific group and even the names of drugs must be mentioned scientific

names. I also hope that all members will participate actively and enrich the

discussion so that the benefit will prevail. May Allah guide us all to what

is good and God is behind the intention.
