Abstract

English vocabulary is considered difficult to learn and use in real life situations by most Iranian learners. In addition, many ofthem feel bored in vocabulary classes since they do not have the opportunity to take part in learning process, therefore, theylack necessary motivation to be pushed forward. Besides, they have not changed their learning habits, such as writing wordson paper, trying to learn by heart or learning passively through teachers` explanations. The reason must be that the maintechniques used to practice in memorization while the features like fun, motivation and effort are ignored in almost all Englishclasses. To help learners find language classes, especially vocabulary lessons more interesting, and to achieve more, theresearcher used word games, which are generally engaged as a source of entertainment to serve an educational purpose, asinstructional tools in practicing newly taught words. Moreover, the researcher compared the effects of two types of word games(cooperative versus competitive) on learners` motivation, attitudes toward their teacher, class atmosphere, and vocabularyachievement, in order to investigate which game type was more successful in this field. In order to achieve this goal, this studyhas been done on 60 male English learners with the age range of 17-19 years old. Among these learners, 40 were consideredas the experimental (in 2 different experimental groups), and the other 20 learners as the control. To gather data, theseinstruments have been used: a motivation questionnaire, a questionnaire about word games, a classroom atmospherequestionnaire, vocabulary tests, and teacher`s interview. Besides, 2 different categories of word games (cooperative versuscompetitive games) were used in this study to compare their effects on EFL vocabulary learning. The results show that bothtypes of word games affect learners` vocabulary learning, increase their motivation, change their attitudes toward their teacher,and also create a positive atmosphere in their classroom. Moreover, through comparing effects of these games, the researcherfound out that for some learners, cooperative word games could affect their vocabulary learning by increasing their motivationand providing a positive atmosphere in their classroom, while for some others, competitive word games were more effective.Consequently, it cannot be stated exactly which type of these games were more successful in this study. Curriculum designers,English textbook authors, and those who train EFL teachers can use these findings and improve English education andlearning in words in English classes in Iran. It other words, it is suggested to use word games in English classes to increaselearners` motivation, vocabulary learning, and also to provide a more positive atmosphere in the classroom.

Abstract

Fifty years after independence, Nigeria is still struggling with the provision of basic health services for its teeming population,now estimated at over 150million. The health care sector is still a labour-intensive handicraft industry, in spite of advances intechnology, and health care provision has now become more complicated than in the past. Infant and under-five mortality ratesare near the highest in the world, and maternal mortality is extremely high. It has the second largest number of people infectedwith HIV/AIDS in the world only next to South Africa and in 2008, between 3million and 3.5million people were estimated to beliving with HIV/AIDS. Nigeria has the fourth highest number of TB cases in the world, with a 2004 estimate of 293 new casesper 100,000 population and 546 per 100,000 total cases. The reasons for a dysfunctional health system include: gross inadequate infrastructural support, electricity, potable water and diagnostic laboratories, very low per capita health spending,high out-of-pocket expenditure by citizens, and a total absence of a community-based integrated system for diseaseprevention, surveillance and treatment amongst others. Some strategies to tackle health sector challenges in Nigeria mayinclude improved access to primary healthcare; strategic and purposeful leadership in health delivery services; increasingfunding to the health sector; amongst others.

Abstract

This study investigated the relative contributions of selected teachers’ variables and students’ attitude towards academicachievement in biology among senior secondary schools in Ondo State, Nigeria. It involved descriptive survey research andex-post facto research designs. The sample, 360 respondents which consists of 180 biology teachers and 180 seniorsecondary school three students were randomly selected from 36 senior secondary schools from the three Senatorial Districtsof Ondo State using stratified random sampling technique. Teachers’ teaching attitudinal scale, Science oriented attitudinalscale and an inventory which requested for data from records on students’ senior secondary school certificate examinationgrades in biology were used for data collection. Data collected for the study were analyzed using correlation matrix andmultiple regression analysis. The results showed that significant relationships existed among the independent variables andstudents’ academic achievement in biology. Also 62.5% of the variance observed in students’ achievement in biology wasexplained by linear combination of the five predictor variables. Students’ attitude was the most potent contributor to theprediction. Teachers’ workload was the least contributor to the prediction. It was recommended that constant workshops andseminars should be made available by government for teachers to attend for the improvement of their teaching skills.Teachers and students were also charged to change their attitudes positively towards the teaching and learning of biology.

Abstract

Social network systems and virtual environment as one of the consequences of the globalization process, and its influences onits users, are discussed in the present study. Some basic concepts, including the necessity of redefining and evenreconceptualizing them, are discussed briefly. This research addresses the facilities as well as the attributes of Facebook as aSocial Network System, and particular features of disembodiment, re-construction, and re-presenting social identities which arealready constructed as a member of small societies. Due to this, “Whether ‘virtual communication environments’, ‘socialnetworks’ are perceived as something like ‘escape way’ from socio-cultural restrictions or not” was questioned. For the purposeof the study, an online questionnaire consisting of 55 close-ended questions, with brief information about the purpose and thesignificance of the study, was posted at various FB users’ profiles. However, only the first 100 volunteer ‘Turkish Cypriot’ userswere taken as the sample.

Abstract

This paper investigates the way in which Indonesian literature has reflected violations of human rights in Indonesia in the lastdecade of the New Order (1990-1998). The regime was authoritarian and responded harshly to any challenge which couldcause trouble to national stability. Some writers, such as Seno Gumira Ajidarma, used the power of allegory to resist thisoppression. The three works examined here – ‘Saksi Mata’, ‘Pelajaran Sejarah’, and ‘Misteri Kota Ninggi’ – can be consideredas a form of resistance literature.

Abstract

This study presents an analysis of the factors affecting the supply and demand of school teachers in Ghana. The findingssuggest that the major pull causing the mismatch in teacher supply-demand equation can be summed up under: a) economicdemand, b) demographic factors and c) market forces. Sixty percent of those sampled constituting 162 of the respondentswere of the view that there was a significant correlation between remuneration and supply while the other 40% (108) notattributing it to remuneration per se, nevertheless saw a link between supply and other economic issues such as end of servicebenefit. Ninety five percent of respondents were of the view that teacher upgrading in higher market premium courses ininstitutions of higher learning exacerbate teacher attrition into other better paid jobs: an indication of non-incentives pullingteachers from the teaching profession. The objective of the study is to contribute to advocacy on teacher issues, especiallyincreased resources as well as innovative funding for the employment of sufficient number of teachers.
