The use of waste as an additional material on the building work was increasingly actively developed, such as straw, styrofoam, bagasse, cow manure. The key drivers of the use of waste is the potential for waste is increasing, due to the depletion of non-renewable resources. Papyrus rod diameter 60 cm, length 30 meters, has a volume of 5,652m3 as well as the edges of the Rods that can be used for construction with a thickness of 3 cm has a volume 0,942m3, Pith and fiber volume content of the stem 4,71m3/rod, then in one rod, there are 2 to 3 bunches each fruit bunches yield as much as 20 to 30 items for one harvest, by weight of fruit fiber 101.2 gram / fruit, Fiber characteristics are round and smooth is expected to reduce cracks in solid concrete brick and also can reduce the use of sand. This study aims to determine the compressive strength of the composition of the additional material of Rods fiber content and Fiber of palmyra fruit with a percentage 3%, 6% and 9%, mixing ratio; 1 cement and 5 sand in the manufacture of solid concrete brick. Rods fiber content used the average Ø1,031mm with a tensile strength of single fiber 39,305N / cm and fruit fiber to an average value Ø0,40mm with a tensile strength of single fiber 33,691N / cm. Making test specimen with a length of 20cm, width 10cm and thick 8cm. The test results of compressive strength after 14 days with the lowest value at 3% of additional material combination of fiber content of 6% fiber stem and fruit by 70,384Kg/cm²with a water content of 15,254% In weight position 2,935Kg as well as the highest value on the combination of additional material 0% rods fiber content and 3% fruit fiber by 98,821Kg/cm² with a water content of 15,031% In weight position 3,058Kg. While N (without additional material) with a compressive strength below the average id 63,704Kg/cm2 with water content of 10,167 in weight position 3,072Kg. Research result of solid concrete brick with additional material of rods fiber content and palmyra fruit fiber was included on the type B70, the average value of the compressive strength of 78.57 Kg / cm² (SNI-03-1348-1989) with a water content of <25%.

Abstract

This paper spotlights a number of daunting challenges that fraught teachers education in Nigeria. Itadjudges senior secondary education as being stuck in limbo, using senior secondary physics as illustratedexamples. It advocates a repositioning of basic elements of teacher education inline with the realities of the21st century.

Abstract

Climatic change is a significant and lasting change in the statistical distribution of weather patterns overperiods ranging from decades to millions of years. Millions of people around the world depend on fish forincome and livelihood. Linked to the strong increase in fish production, employment in capture fisheriesand aquaculture has grown substantially in the last three decades, with an average rate of 3.6 percent.Climatic changes affects spawning sites of fisheries resulting in the reduction of fish biomass, destruction ofcoral reeves, distortion of food web and food chain, and the reduction of caught fisheries. Shifts in oceansalinity are occurring, with near-surface waters in the more evaporative regions of most of the world’socean increasing in salinity, while marine areas in high latitudes are showing decreasing salinity due togreater precipitation, higher runoff, melting ice and other atmospheric processes. Importantly, increase insalinity affects fish spawning site which in turn influences fish population. This will translate to less incomefor fishers as they record less catch. In an attempt to meet up other social responsibilities, fishers mayresort to other more dangerous methods of catching fish like toxic chemicals, explosives and dynamite.Serious sanctions must be put in place to restrain fishers from adopting these dangerous methods ofcatching fishes while effort must also be intensified to improve aqua culture production

Abstract

Global managers and leaders have exceptionally open minds. They most often respect how differentcountries do things and they have the imagination to appreciate why they do them that way. But, they arealso incisive. They sort through the debris of cultural excuses and find opportunities to innovate .There isneed to develop the global mindset of leaders/managers, teams, individuals, and the entire Africanpopulace to enhance global sustainability. The existing scenario in Africa indicates that it does not haveenough leaders within global competencies. It is essential to identify African leadership potentials that helpto sustain competitive advantage in a dynamic global/ local environment. This advantage of course isachievable through global mindset development. The concept and idea of sustainable development iswidely accepted, and good progress has been made on sustainable development metrics; yet itsimplementation has been largely unsuccessful especially in Africa. The position of this paper is that globalmindset remains a sine qua non for sustainable development anywhere in the world. A synergy betweenglobal mindset and sustainable development has therefore been established. It was recommended amongothers, that African leaders should be more proactive and also see the development of global mindset as apriority.

Abstract

The inability of secondary school graduates of Agriculture to secure jobs or be self-employed has sustainedthe perceived generation gap, which has been blamed on the way and manner in which secondaryeducation Agriculture curriculum is implemented. Four objectives were addressed by the study. A total of200 teachers of Agriculture randomly selected from 298 secondary schools across the three EducationZones of Imo state constituted the study sample. A questionnaire structured on a 4- point rating scale andwith stability coefficients of 0.82, 0.76, 0.70 and 0.86 for sections B to E respectively was used in generatingdata for the study. Findings of the study indicated that some teacher-related factors are necessary foreffective implementation of the curriculum among which is teacher’s moral disposition, commitment, andteaching styles were indicated. Use of modular teaching methods, establishment of good school –community relationships and combined use of performance–based test and written test used for thepurpose of occupation skills acquisition.

Abstract

This paper attempts to examine the roles of Information Communication and Technology (ICT) inVocational and Technical Education (VTE) in Nigeria. To achieve this, the definitions of ICT and VTE weregiven. The benefits of ICT and the use of ICT were also discussed. The challenges of VTE were alsohighlighted before the exposition on the role of ICT in VTE. It was concluded that the emergence of ICTremain at the centre of global socioeconomic transformation. The paper recommended that schoolsoffering VTE should be connected to ICT facilities and the staff should be properly trained to be ICTcompliant.

Abstract

As world population increases, and as more and more individuals make increasing demands on the earth’sresources, the mandate for effective Sustainability Education (SE) becomes more urgent. This paperdescribes a longitudinal evaluation of a project currently being undertaken in government primary andsecondary schools in New South Wales, Australia, funded by the NSW Department of Education andCommunities (DEC). The Climate Clever Energy Savers (CCES) Project is designed to raise awarenessamong school students about ways of reducing electricity consumption at their schools. Students areinvited to tender for funds of up to $2000.00 to support a program (such as an education campaign, orbuilding or appliance modification) to reduce electricity consumption. The overarching research questionconcerns the extent to which and ways in which the program has achieved the desired behaviour changesand educational outcomes. We have found the project to be highly effective, but also suggest somemodifications to further enhance its effectiveness.

Abstract

The focus of this research work was to develop a sustainable real-time e-learning system with the contentsto be delivered via the Internet using online real-time processing techniques. We present the conceptualframework of the model of real-time e-learning system to reduce congestion in Nigeria higher institutionsusing Yaba College of Technology as a case study. The system if developed and implemented, it willdecongest the population of students in our higher institutions, hence reduce or eliminate the problemsassociated with students population congestion in our schools.
