Critical thinking skills are essential in education. Unfortunately, education policymakers and curriculum developers in Malawi have not given a   concerted effort to promoting critical thinking skills in schools. OSISA has indicated that there is no clear evidence in the Malawi primary and   secondary school curricula that promoting critical thinking is considered   important. In this paper, we examine the definitions of critical thinking,   creative thinking, reflective thinking and we are of the view that there is a level of overlap amongst them. We also look at how the behaviours of   egocentrism and sociocentrism can undermine critical thinking. The study draws on Piaget and Vygotsky’s theory of (social) constructivism to advance approaches and practices that teachers can employ to promote critical   thinking in learners. We develop a lesson plan that incorporates critical  thinking skills and show how teachers can correct egocentric and    sociocentric tendencies that might impede critical thinking in learners. We  claim that students equipped with critical thinking skills can contribute   intellectually, socially, culturally and economically to society. Key words : critical thinking, social constructivism, lesson plan, egocentric, sociocentric
批判性思维技能在教育中是必不可少的。不幸的是,马拉维的教育政策制定者和课程开发人员并没有齐心协力在学校里培养批判性思维技能。该组织指出,在马拉维的小学和中学课程中,没有明确的证据表明促进批判性思维是重要的。在本文中,我们研究了批判性思维、创造性思维和反思性思维的定义,我们认为它们之间存在一定程度的重叠。我们还研究了自我中心主义和社会中心主义的行为如何破坏批判性思维。该研究借鉴了皮亚杰和维果茨基的(社会)建构主义理论,提出了教师可以用来促进学习者批判性思维的方法和实践。我们制定了一个包含批判性思维技能的课程计划,并展示了教师如何纠正可能阻碍学习者批判性思维的自我中心和社会中心倾向。我们认为,具备批判性思维能力的学生可以在智力、社会、文化和经济方面为社会做出贡献。关键词:批判性思维,社会建构主义,教案,自我中心,社会中心

Physical availability of water resources is beneficial to man when it is readily accessible. Oyo State is noted for abundant surface water and appreciable groundwater resources in its pockets of regolith aquifers; as it has about eight months of rainy season and a relatively deep weathered regolith. In spite of this, cases of water associated diseases and deaths have been reported in the rural areas of the state. This study attempts to conduct an investigation into accessibility to potable water in the rural areas of Oyo State, Nigeria via the component approach of water poverty index (WPI). Multistage method of sampling was applied to select 5 rural communities from 25 rural LGAs out of the 33 LGAs in the State. Data were collected through the administration of 1,250 copies of questionnaire across 125 rural communities. Component Index method as developed by Sullivan, et al (2003) was modified and used in this study. The results show that values of WPI were generally low, ranging from 11.29% in Itesiwaju LGA to 47.89% in Atisbo LGA out of 100% maximum obtainable; indicating that these rural areas are water stressed. The paper recommends aggressive human development efforts and the need for massive improvement in water infrastructure in the state. Key words : Water Poverty Index (WPI), Water accessibility, Rural Areas.
当水资源易于获取时,物质上的可得性对人类是有益的。奥约州以其丰富的地表水和风化层含水层中可观的地下水资源而闻名;因为它有大约八个月的雨季和相对较深的风化层。尽管如此,在该邦农村地区仍报告了与水有关的疾病和死亡病例。本研究试图通过水贫困指数(WPI)的组成方法对尼日利亚奥约州农村地区的饮用水可及性进行调查。采用多阶段抽样方法,从该州33个农村地方自治团体中的25个农村地方自治团体中选择5个农村社区。通过管理125个农村社区的1,250份问卷收集数据。本研究对Sullivan等人(2003)提出的成分指数法进行了改进和使用。结果表明:WPI值普遍较低,在100%的最大值中,伊特西瓦州LGA的WPI值为11.29%,而Atisbo LGA的WPI值为47.89%;这表明这些农村地区水资源紧张。该报告建议积极的人类发展努力和大规模改善该州水基础设施的必要性。关键词:水贫困指数,水可及性,农村

Education is perceived here as schooling as well as the processes involved in gaining new knowledge, skills and attitude for the positive development of the beneficiary and that of the society. The use of technology that enables communication and the electronic capture, processing and transmission of information in education is an innovation that many nations across the globe struggle to achieve. This paper centres on ICT enabled education and ICT driven e-learning strategies: benefits and setbacks in Nigeria education system. It is in fact among the academic struggle to bring to the lime-light, the knowledge of ICT to scholars especially in the domain of education. The paper captured interesting discussion on the concept of information and communication technology including the various approaches in ICT enabled education. To further extend the knowledge of the audience, ICT driven teaching and learning strategies and the benefits of ICT applications in education were also covered. Specifically, ICT benefits to students and parents as well as setbacks of ICT use in education were explicitly highlighted. The paper concludes that the use of ICT in education is gradually taking shape in some tertiary institutions in Nigeria. On the other hand, ICT use is sparingly observed in the secondary and primary schools. The paper recommends amongst other measures that the federal republic of Nigeria should come up with strong policy on ICT use in the education system.
在这里,教育被视为学校教育,以及为受益者和社会的积极发展而获得新知识、技能和态度的过程。在教育中使用使通信和电子捕获、处理和传输信息成为可能的技术,是全球许多国家努力实现的一项创新。本文的重点是信息通信技术支持的教育和信息通信技术驱动的电子学习战略:尼日利亚教育系统的利益和挫折。事实上,在学术斗争中,把信息通信技术的知识带到聚光灯下,尤其是在教育领域。该文件对信息和通信技术的概念进行了有趣的讨论,包括信息和通信技术教育的各种方法。讲座亦介绍了资讯及通讯科技的教学策略,以及资讯及通讯科技应用于教育的好处,以进一步扩展听众的知识。具体而言,与会者明确强调了信息通信技术对学生和家长的好处以及在教育中使用信息通信技术的挫折。该论文的结论是,在尼日利亚的一些高等教育机构中,在教育中使用信息通信技术正在逐步形成。另一方面,在中学和小学使用信息通信技术的情况很少。除了其他措施外,该文件建议尼日利亚联邦共和国应制定强有力的政策,在教育系统中使用ICT。

Pub Date : 2014-07-03 DOI: 10.4314/STECH.V3I2.6
B. Mbam, G. Odachi
This research work focused on development of a model of web based virtual University Administration for Nigerian universities. This is necessary as there is still a noticeable administrative constraint in our Universities, the establishment of many University Web portals notwithstanding. More efforts are therefore needed to enhance or improve on the software that drives these portals to make them more efficient and render real time services. The model enables members of academic community to set up curriculum, register students and staff, enter exam scores, post news, view results, pay school fees, request for transcripts, obtain vital information from the university and update information on daily basis. The model has a watch-dog monitor called Web Patrol that monitors and keeps a log of the transactions by students and staff. The methodologies adopted for this work are top-down, prototyping and Structured Systems Analysis and Design Methodology (SSADM). This research work helps in bringing university administrative products and services to the door steps of people, thereby reducing administrative bottleneck witnessed in our universities today. It generates results and transcripts, thereby solving the current problems of delay in result and transcript processing and transfer in our universities.
本研究工作的重点是为尼日利亚大学开发一种基于网络的虚拟大学管理模式。这是必要的,因为尽管建立了许多大学门户网站,但我们的大学仍然存在明显的行政约束。因此,需要更多的努力来增强或改进驱动这些门户的软件,以使它们更有效并提供实时服务。该模型使学术社区的成员能够设置课程、注册学生和员工、输入考试成绩、发布新闻、查看成绩、支付学费、请求成绩单、从大学获取重要信息以及每天更新信息。该模型有一个名为“网络巡逻”(Web Patrol)的监督狗监视器,它监视并记录学生和员工的交易。这项工作采用的方法是自顶向下、原型设计和结构化系统分析和设计方法(SSADM)。这一研究工作有助于将大学行政产品和服务带到人们的家门口,从而减少目前我国大学行政管理的瓶颈。它生成成绩和成绩单,从而解决了目前我国高校成绩和成绩单处理和转学延迟的问题。

Infertility, as a social and cultural problem affecting individuals and  families, makes People Living with Infertility (PLWI) to seek solution through different pathways, but with little or no information on patriarchal barrier(s) militating against counselling in the course of treatment. The study, therefore, investigated infertility treatments and counselling in the context of patriarchy among Ijebu, south western Nigeria. The study  utilized Ecology Model as theoretical guide and cross-sectional survey design was adopted for data gathering. Two local government areas were purposively selected: Ijebu North and Ijebu-Ode LGAs. Infertile females were purposively selected in the churches and other care centres.  Questionnaires were administered on snowball basis. Eight in-depth  interviews (IDIs) were conducted for two medical doctors, two Traditional  Birth Attendants (TBAs), two opinion leaders and two clergy. Quantitative  data were analysed with simple percentage. Content analysis was used for qualitative data. Assisted reproductive technologies - ARTs were not  acceptable. 62% agreed that government should intensify legislation,  health education; legal and medical counselling centres that would provide level playing ground for PLWI. PLWI to have easy access to the  treatments, social and financial costs should be de-emphasized and the need for counselling should be emphasized in case of ART Key words : Patriarchy, Infertility, Health-seeking behaviour, Counselling, Gender inequality.
不孕症作为一个影响个人和家庭的社会和文化问题,使不孕症患者(PLWI)通过不同的途径寻求解决方案,但很少或根本没有关于在治疗过程中阻碍咨询的父权制障碍的信息。因此,这项研究调查了尼日利亚西南部Ijebu地区父权制背景下的不孕症治疗和咨询。本研究以生态学模型为理论指导,采用横断面调查设计进行数据收集。有目的地选择了两个地方自治团体地区,即伊济北和伊济奥德地方自治团体。在教堂和其他护理中心有目的地选择不孕妇女。问卷以滚雪球的方式进行。对两名医生、两名传统助产士、两名舆论领袖和两名神职人员进行了八次深入访谈。定量资料用简单百分比法进行分析。定性资料采用内容分析。辅助生殖技术(art)不被接受。62%的人认为政府应加强立法、健康教育;法律和医疗咨询中心,为PLWI提供公平的竞争环境。为了使艾滋病毒感染者更容易获得治疗,不应强调社会和经济费用,并应强调在抗逆转录病毒治疗情况下咨询的必要性。关键词:父权制、不孕症、求医行为、咨询、性别不平等。

The role of rainfall variability in reservoir storage management at Shiroro hydropower dam, Nigeria 降雨变率在尼日利亚Shiroro水电站水库管理中的作用
Pub Date : 2014-07-03 DOI: 10.4314/STECH.V3I2.2

Reservoir operation and management is usually patterned after the background of long standing water resources management experience. Reservoir management for optimum power production at any hydropower station requires constant assessment of the quantity of available water. The hydrographic responses of flow monitoring and statistical analysis of instrumental hydro-met records, especially rainfall and stream flow provide the necessary springboard for soundoperational decisions. Statistical analysis of hydrometeorological data (rainfall, inflow, reservoir storage and turbine release) at Shiroro dam was carried out with the aim of detecting spatio - temporal trends. Correlation and regression analysis were used to develop models for the variables. The correlation of between 0.120 and 0.774 revealed favourable relationships between the variables. This has invariably affected reservoir storage at the dam as excess water is released from the dam to sustain power generation over the years. It is  recommended that dam operators optimize the release of water from  Shiroro dam and ensure continuous monitoring of changes in  hydrometeorological variables to provide early warning systems for  effective performance of the dam and to protect downstream environment. Key words : Rainfall Variability, Reservoir Management, Environment, Dam, Storage
水库的运行和管理通常是在长期的水资源管理经验的背景下进行的。任何水电站为了实现最佳发电而进行的水库管理都需要不断评估可用水量。流量监测的水文响应和仪器水文气象记录的统计分析,特别是降雨和水流,为合理的业务决策提供了必要的跳板。对四郎坝的水文气象资料(降雨、入水量、水库蓄水量和水轮机放水量)进行了统计分析,以探测其时空变化趋势。采用相关分析和回归分析对各变量建立模型。相关性在0.120和0.774之间,表明变量之间存在良好的关系。这必然会影响大坝的蓄水量,因为过剩的水会从大坝中释放出来,以维持多年的发电。建议坝方优化四郎坝放水,持续监测水文气象变量变化,为大坝有效运行提供预警系统,保护下游环境。关键词:降雨变率;水库管理;环境

Nigeria has a population of about 160 million people and an area of land covering 200,000 square kilometres. Amongst the numerous natural resources in Nigeria; water resources is most plenteous and is developing at a fast pace. Because of the lack of sound early development policy and meaningful investments, the rational use of water resources poses a great problem and challenge to the nation. These have been seriously tackled by the River Basin Development Authorities which were set up to manage the resources. Total expenditure on various water projects by the federal ministry of water resources has run into billions of Naira since the establishment of the 11 river basic development. The state government ministries of water resources have also impacted on the management of water resources nationwide and in many cases with a financial and technical support from the federal ministry of water resources and donor agencies like the UNESCC, UNICEF, and others. Most recently, the private sector has come into water resources development especially the development and management of potable water through the private, public sector partnership PPP. This paper therefore examines the sources of surface and ground water resources in Nigeria; the goal and present organisation of water management in Nigeria Groundwater protection and vulnerability, water management under drought and flood conditions. Suggestions were made on ways of planning sustainable water supply systems for Nigeria Key words: Water Resources, Management, Strategies, Climate Change
尼日利亚人口约1.6亿,国土面积20万平方公里。在尼日利亚众多的自然资源中;水资源最为丰富,发展速度也很快。由于缺乏健全的早期发展政策和有意义的投资,水资源的合理利用给国家带来了巨大的问题和挑战。为管理这些资源而设立的流域发展局已经认真解决了这些问题。自11条河流基础开发项目建立以来,联邦水利部在各种水项目上的总支出已达到数十亿奈拉。州政府水利部也对全国的水资源管理产生了影响,在许多情况下,他们得到了联邦水利部和联合国教科文组织、联合国儿童基金会等捐助机构的财政和技术支持。最近,私营部门通过公私合作伙伴关系参与水资源开发,特别是饮用水的开发和管理。因此,本文考察了尼日利亚地表水和地下水资源的来源;尼日利亚水管理的目标和目前的组织地下水保护和脆弱性,干旱和洪水条件下的水管理。对尼日利亚可持续供水系统的规划提出了建议。关键词:水资源,管理,战略,气候变化

Amongst the numerous natural resources in Nigeria; water resources is most plenteous and is developing at a fast pace. Because of the lack of sound early development policy and meaningful investments, the rational use of water resources poses a great problem and challenge to the nation. These have been seriously tackled by the River Basin Development Authorities which were set up to manage the resources. Total expenditure on various water projects by the federal ministry of water resources has run into billions of Naira since the establishment of the 11 river basic development. The state government ministries of water resources have also impacted on the management of water resources nationwide and in many cases with a financial and technical support from the federal ministry of water resources and donor agencies like the UNESCC, UNICEF, and others. Most recently, the private sector has come into water resources development especially the development and management of potable water through the private, public sector partnership PPP.

Nigeria is having about 17.5 million orphans and Ekiti State the study area contributes about 70,000. This may increase with the prevalence of HIV from one percent to 1.4 percent in the state. This study uses the Orphans Vulnerable Index and Child Status Index to identify and enrol Vulnerable Children (VC) in the two LGAs of focus in order to identify the needs of VC and care givers. A total number of 402 VC were enrolled out of 433 identified from six political wards in the LGAs. There were 51% male and 49% female, 44% and 56% from Ido Osi and Moba LGAs respectively while the age distribution shows that more than 40% of the VC is within 10-14 years of age. Using the CSI scores, more than 65% of the VC has poor access to adequate nutrition, shelter and health care services while about 63% of the VC has poor access to education, social protection and psychosocial wellness. The findings represent the poor socioeconomic status of Nigerians, though the Ekiti State faired a bit better than states outside of the southern Nigeria Zones. Keywords : Vulnerability score; HIV; community; enrollment.
尼日利亚有大约1750万名孤儿,埃基蒂州的研究地区贡献了大约7万名孤儿。这可能会随着该州艾滋病毒的流行率从1%增加到1.4%而增加。本研究采用孤儿易受伤害指数和儿童状态指数对两个重点地区的弱势儿童进行识别和登记,以确定弱势儿童和照顾者的需求。从地方政府六个政治区确定的433名VC中,共有402名VC注册。其中男性占51%,女性占49%,Ido Osi和Moba的lga分别占44%和56%,年龄分布显示,超过40%的VC年龄在10-14岁之间。根据CSI得分,65%以上的逃亡者难以获得足够的营养、住所和保健服务,约63%的逃亡者难以获得教育、社会保护和心理健康。尽管埃基蒂州比尼日利亚南部地区以外的州公平一些,但调查结果表明尼日利亚人的社会经济地位较差。关键词:漏洞评分;艾滋病毒;社区;招生。

Mathematics Education for National Competitiveness and Prestige 提高国家竞争力和威信的数学教育
Pub Date : 1900-01-01 DOI: 10.4314/STECH.V4I1.13
F. Uveruveh, P. Perekeme
Mathematics education has always been a key factor in improving a country’s productivity and competitiveness. Proficiency in mathematics education implies a high-level of cognitive skills among the labour force, in other words, a high quality of human capital, which leads to technological innovation and productivity gains. This paper discusses some examples of application areas where mathematics education is emerging as vital components with great opportunities for inter discipline research. It is recommended that the current interaction between mathematics education and other disciplines will be further strengthened by ensuring that adequate time is devoted to classes and to eliminate the belief that mathematics is not important in their lives
