Abtracts: Large English classes can cause many problems for the teacher and the young learners. It may seem impossible in such classes to organize dynamic and creative teaching and learning sessions. For example, it is impossible for the teacher in such classes to ensure individual participation of the young learners in the process of language practice and language use. Large classes can never be suitable for dealing with the new demands of language teaching. In other words, large classes cannot facilitate accomplishing teaching and learning based on the principles underlying communicative approach adopted in the primary 5 and 6 textbook, which is intended to build up the learner's confidence in going from organizing information to using the different language skills. The study examines the negative effects of the large number of young learners in the classroom. It intends to shed light on problems encountered in teaching English as a foreign language for communication to such classes. Research procedure and techniques to be used to collect data required for this study will be fulfilled by the use of teacher's questionnaire, as well as data drawn from informal interviews with English teachers in some primary schools in Tripoli. The actual teaching environment in primary schools is unsuitable for teaching English as a foreign language to young learners and at the same time, it prevents pupils from learning English properly. This is because most of the classes which have been visited and observed were crowded with large number of pupils. It has been noticed that this situation was problematic and uncomfortable for both the teachers and the pupils. Teaching English as a foreign language for communication to young learners requires small number of pupils in each class for the process to be successful. Young learners need special teachers' care and attention. They need enough time for each learner to practise the language and perform the various activities. Therefore, it has been recommended that large classes must be reduced to normal-size classes.

Abstract Biocides (disinfectants and antiseptics) are used extensively in hospitals and other health care settings for a variety of applications. However, their antibacterial effectiveness is not always well stated by the manufacturers and consumers find it difficult to choose the right product according to their needs. Therefore, the aim of this study was to evaluate practically achieves disinfection efficacy of locally available disinfectants and antiseptics on surfaces and infectious microbiological utilities of Tripoli Medical Center (TMC). Fourteen biocides; Ten disinfectants (Dex36, Dex50, Dex53, Mzid-S, Mzid-AF, Deson, Dettol, Seem, Chlor and Wipol) and four antiseptics (HiBi, Esept, Emed and Desman) were tested at concentrations recommended by manufacturers on surfaces, walls and different utilities that were contaminated by locally circulating six isolates of Bacillus cereus, Staphylococcus haemolyticus, staphylococcus aureus, Klebscilla pneumonia, Acinetobacter baumannii, and Pseudomonas aeruginosa using four standard evaluation test procedures (capacity test, diffusion test, in-use test and suspension test). Results showed the highest average log reduction (7.4) of test bacteria was given by quaternary ammonium based disinfectants; Dex50, Dex53, Deson-AF and Mzid-S. A comparable average log reduction of test bacteria was noted (7.0, 7.2 and 7.3) for Deson-AF, Dex.50 and Dex.53 respectively. In contrast HiBi as an alcoholic based antiseptic gave the highest average log reduction (7.2) against tested bacteria. Desman, Emed and Wipol antiseptics had poor antibacterial activity on tested bacteria causing almost undetectable log reduction in cell viability. From contamination point of view, five critical departments in Tripoli Medical Centre (TMC) namely; Neonatal Intensive Care Unit (ICU), Surgical ICU, Dermatology, Oncology, and Urology departments were found contaminated with six types of bacteria. Bacillus cereuses followed by Klebscilla pneumonia were the most bacteria spread in whole five mentioned departments, particularly in dermatology department. Staphylococcus haemolyticus was next most widespread bacterium and almost isolated equally from the five medical departments. Acinetobacter baumannii had been isolated from Neonatal ICU; whereas Staphylococcus aureus and Pseudomonas aeruginosa had been isolated from Oncology Department and Surgical ICU respectively. In addition, Dex36, Chlor, Chlor, Wipol, Desman and E-med exhibited bacterial contamination in both capacity and in-use tests. In conclusions, quaternary ammonium compounds (QACs) and combination of QACs with aldehyde formulations were found to be the best disinfectants for disinfection of contaminated surfaces.

Abstract Lexical competence can be defined as one's ability to use words differently and fully. This study is an attempt to investigate the effective techniques for testing the lexical competence in foreign language teaching. The study consists of four chapters. Chapter one is an introduction to the study. It focuses on the background of the study, and the problem of the study as well as the purpose and the hypotheses of the study. Chapter two deals with the definitions, characteristics, types and methods for testing lexical competence were given. This chapter also focuses on the testing language skills and what to test in testing learners' lexical competence. Chapter three is the practical part of the study. It includes subjects of the study and data for the study. The data consisted of the students' test and the teachers' questionnaire with their analysis and results. Chapter four is concerned with the concluding remarks that have been drawn from the study. Some recommendations on the appropriate use of testing vocabulary are also suggested in order to overcome the teachers and the student’s problems for techniques in testing and teaching lexical competence.
