Objective Access to improved sanitation is a fundamental human right and an important aspect of Public Health.However,an estimated thousands of people in Ghana especially,the West Mamprusi Municipal Assembly(WMMA)still have no access to adequate toilet facilities.This has brought untold health repercussions to the inhabitants,the community,and the environment at large.To address this menace,the community-led total sanitation(CLTS)was implemented.This study aimed to assess communities’perspectives on the implementation of CLTS and to understand the factors influencing its success and failures.Methods A mixed-method approach involving sequential qualitative and quantitative methods was employed in this study.Participants for the quantitative study were randomly selected and surveyed using questionnaires.The qualitative study employed focus group discussion involving purposively sampled participants including assembly members,opinion leaders,and assembly staff.Results The CLTS program in WMMA realized an apparent use of construction and proper use of household latrines leading to a reduction of open defecation free(ODF)and two communities achieving sanitized status in the history of the study area,enabling the training of latrine artisans and natural leaders to facilitate the CLTS expansion and sustainability,improved sanitation and hygiene,strengthened the enforcement of community rules and regulations and many others.Conclusion The CLTS program has received more widespread acceptance in the study area than the previous government policy of constructing public toilets,which was greeted with massive failures due to poor implementation.To ensure that gains achieved through CLTS implementation are sustained longer,it is recommended that chiefs and opinion leaders should be involved in the CLTS programs to ensure checks and enforcement.The entrenchment of bylaws and more education to address enduring myths and misconceptions will sustain the program.Subsidies in the form of sanitation loans for latrine construction materials by the government and supporting non-governmental organizations(NGOs)will be paramount in sustaining ODF. 展开更多

Nowadays,the Communicative Language Teaching Approach has gained significant popularity in the field of foreign language teaching.However,there appears to be a stagnation in its application effects.Therefore,this thesis aims to investigate the present state of CLT implementation and identify the factors influencing its execution within English major classrooms at Chinese universities from a student perspective.30 students responded to the questionnaire and 5 students participated in interviews to provide detailed insights.Through analysis,it was observed that CLT has been widely used in English classes and received positive feedback from students.Factors including the Test-oriented Educational system,teacher factors,student factors,and the Chinese traditional Confucius idea about teaching have an important impact on its implementation.Additionally,this article offers potential recommendations aimed at reconciling the CLT Approach with the Chinese educational context. 展开更多

Language teaching approaches are always changing according to social needs for various talents and there is no exception for Communicative Language Teaching(CLT).From 1960s,people become more and more interested in communicative function of languages.Communicative Competence,Functional Linguistics,Speech Act Theory and related learning theories help the CLT form the teaching aim of cultivating students'communicative ability.Scholars start to regard language communicative competence as the final teaching purpose.This article will explore CLT in terms of language teaching views,advantages and disadvantages.What is more,it comes to the following conclusions:there exists no language teaching approach that is absolutely superior,including CLT.Language teachers should use different approaches flexibly so as to reach the teaching aim. 展开更多

Though China's present situation in English language teaching is quite favorable,some problems are still very outstanding.It seems that the communicative competence of Chinese students is not that satisfactory.The Communicative Language Teaching(CLT) approach,which regards"communicative competence"as the goal of language teaching,is becoming more and more popular in China's English language teaching.This paper shows that the CLT approach does work in improving students' communicative competence to some degree,through reviewing relevant literature on this approach.However,it is not a panacea to solve all the problems occurring in students' communicative competence for it also has some weak points.Several suggestions were proposed to enhance students' grammatical competence as well as the communicative block due to cultural differences.It is also advisable for teachers to be as flexible as possible in choosing the teaching techniques and adding whichever input needed to effectively achieve the main goal of making students both grammatically accurate and communicatively proficient. 展开更多

In these, attention is paid to the social context (oral conventions with regard to using language appropriate for a particular social situation).In the classroom, this objective is achieved through role play or simulations in pairs or groups, where the aim is not only effective communication but the socially appropriate use of language, correct register, etc. 展开更多

Based on the brief overview presented above,a more direct,systematic approach toteaching communicative language abilities appears to be emerging gradually along the lines of Richards'(1990)direct approach.Such an approach requires,first,a detailed description of what communicative competence entails so that the subcomponents can be used as some kind of content base in syllabus design.Then the classroom activities canbe developed for each of the selected language areas.Thisdoes not necessarily implya return to traditional,structural syllabi.Pedagogic tasks combined with a systematic focus on form,as outlined by Long and Crookes(1992),could well function as the primary organizational units in a direct communicative syllabus. 展开更多
