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.

Abstract

Distance learning programmes are “alternative models” of the teaching and learning situation where students carry outtheir studies remotely via the internet or videos, cassettes or webcasts” in borrowed classrooms. The advantages of DLPsinclude: availability, self- directed, cheaper, little or no time spent in rigid classroom settings, accessibility, no travel expenses,and working at one’s convenience. These programmes can be quite exciting to those who can afford them in and out of tightschedules and they have become very popular in a modern and technological world such as ours. They afford working adultsopportunities to further their educational aspirations without leaving their jobs. The present paper tries to examine the strengthsand weaknesses of one of these programmes, the Continuing Professional Development (CPD) in Nigeria, in order to ascertainits quality and positive impact on the learners. Our major findings are that distance learning programmes are needful but thelaxities that come with them need to be checked for more qualitative student/ trainee output. The CPD in particular is aprogramme rich in content and purpose but its workability and modus operandi as designed by the British Council and TheNational Teachers Institute of Nigeria is not satisfactory. There is need for urgent reformations for the attainment of desiredresults in terms of quality.

Abstract

The study centered on determining the effect of token economy on academic achievement of secondary schoolstudents. Demonstration Secondary School, Federal College of Education (Technical), Omoku, Rivers State, Nigeria was usedfor the study. Eighty (80) Junior Secondary 3 Integrated Science students and eighty (80) Senior Secondary 1 Biology studentsmaking up one hundred and sixty (160) students of the chosen school, during the 2009/2010 academic session constituted thestudy sample. Each level of students taught by the same teacher was divided into experimental and control groups. Theexperimental groups were motivated with token economy during the lessons while the control groups were not motivated. Rawscores of the students from the two tests they were given made up data for the study. Data analysis involved the use of meanscores and t-test of significant difference between two independent group mean scores, supported by F-test of homogeneity oftwo independent group variances. It was found out that the experimental groups put up higher academic achievement than thecontrol groups. It was also found out that token economy had significant effect on academic achievement of the experimentalgroups. These findings and their counseling implication were discussed

Abstract

Professional development for teachers is an essential element of plans to improve the quality of education.Professional development in a broader sense refers to the development of a person in his or her professional role. Morespecifically, professional development of teachers refers to the achievement of enhanced learning experience in research andteaching with synchronized system so that he/she could deliver effectual knowledge to his /her students in particular and to thesociety as a whole. Exploring this imperative aspect of teaching human resource in universities, current study analyzes theinitiatives taken by public universities of Pakistan for professional development of their teachers. The aim of this explanatorystudy is to investigate the issues and challenges regarding professional development mechanisms of public universities ofPakistan. It elaborates their performance development procedures and strategies and unearths the influential factors andchallenges which are faced by these university teachers regarding performance development systems. The sample of the saidstudy comprised of randomly selected teaching staff of five major Public Universities of Pakistan. Along with detailquestionnaires, in depth interviews had been conducted with teaching staff of the sample universities in order to achieve thedeeper insights of the challenges and issues regarding teachers’ professional development. The study reveals that foreignscholarships to university teachers, research grants and training programs are various effectual measures taken by HigherEducation Commission of Pakistan for Public universities. However, comprehensive monitoring system, quality assurance andimpact measurement of the said measures are lacking elements which create dissatisfaction among teachers in publicuniversities of Pakistan. Also, lack of training for improved teaching in semester system, communication gap among seniors andjunior faculty, decreased guidance for modernized research conduction, overburdened teaching load are some of the hinderingfactors in professional development of teachers which are been revealed by the current research.

Abstract

In this paper I intend to locate a fresh basis on which alternative theories of environment from the African worldviewcould be explored; one which will improve the literature on environment as well as diversify the basis for producing positions thatcould mediate in the tensions that define environmental problems and principles. I shall do this by (i) articulating the moralprinciples of the world and how it suggests an idea of environmental ethics;(ii)locating the philosophy that interprets traditionalreligious practices and the environmental principles that could be derived there-in. I shall demonstrate how (iii)these strands ofideas provide positions that strongly suggest alternative but valuable basis for environmental ethics anchored on Africanworldview and its theoretical and practical potentials for promoting the growth of environment.

Abstract

This study investigated the economic viability of Yam Minisett Production and the problems affecting minisettenterprise in Ogba/Egbema/Ndoni Local Government Area of Rivers State. A sample size of one hundred (100) respondents,was purposively and randomly selected, and was used for this study. Data collected were analyzed using costs/returns analysisto determine the viability of yam Minisett production and statistical mean derived from Likert rating scale with four options, todetermine the problems associated with yam Minisett production/enterprise in the area. The result, revealed a Net Farm Income(NFI) of (N76, 810.00) and a Gross Margin (GM) or a Return to Management (RM) of N82, 620.00, an indication that yamminisett production is profitable/viable. The result shows that the Gross Margin alone is capable of taking care of another cycle ofproduction of seed yam conveniently without sourcing for extra fund elsewhere. Also shown, was the Return per Naira (R/N)from seed yam production which was put at 0.91, and which means that, from every N1.00 employed in the production of seedyam in the study area, 91k was realized, which is another indication of the viability of seed yam production. Problems identifiedin their order of degrees include: yam minisett production as a micro business for poor people (with weighted mean score =3.38); cost of labour (3.00); lack of awareness of yam Minisett production as an enterprise (2.96); land acquisition problem/soilproblem (2.82); fertilizer unavailability (2.70), etc. Based on the findings, this study recommended among others that: ExtensionAgencies in the area should beef up their awareness strategies in sensitizing the farmers, women and youths inclusive to gobeyond practicing Minisett techniques only to raise seed yams for household use, but should embrace it as a viable business toearn a good living; Also, that Governments/non-governmental organizations should not slack in giving incentives in form ofgrants, subsidies, soft loans and other farm inputs to productive farmers in the area. These incentives should be timely so as toachieve the purpose for which they are given.

Abstract

This paper explores the trajectories between teacher capacity building and effective teaching and learning withparticular reference to the Nigerian context where the education system is facing unprecedented challenges. Paradoxically, thesolutions appear to be elusive. This paper argues that as micro-level practitioners, teachers constitute the nexus of anysustainable transformation of the system. To achieve this goal as well as to stem the tide of teacher underperformance, a centralargument in the paper is that building teacher capacity is not only critical to successful teaching and learning, it should also bethe starting point for reconstituting the education system. Towards this end, the paper identifies three context-responsive areasof strategic intervention vis à vis teacher capacity building.

Abstract

The essence of language teaching in Nigerian schools is to improve the communicative competence of students inEnglish Language. The frequent poor performance of students in English Language means that language teachers need toreconsider the appropriateness of the teaching methods. In view of the fact that there are students with learning disabilities inmainstream schools, this paper highlights some motivational strategies that can enhance the communicative competence ofstudents with learning disabilities. The paper explains in details these motivational strategies and the benefits. Finally, the paperconcludes by calling on language teachers to adopt an eclectic method in language teaching through the use of the pedagogicalstrategies examined. It is hoped that these motivational strategies would be adopted for corrective and remedial instruction inlanguage teaching.

Abstract

Educators rely on verbal communication as a central tool for providing students with valuable information for academicdevelopment. Our daily nonverbal behaviors reveal who we are and impact how we relate to other people. Nonverbalcommunication has implication for the teacher as well as the learner. It is often said that one can always recognize a languageteacher by their use of gesture in normal conversation. Feldman (1990) asserts that research regarding the use of non-verbalcues in education demonstrates that educators often send messages regarding their expectations via non-verbal cues such asfacial expressions and overall body language. These nonverbal cues, according to Feldman, can have a notable impact onoutcomes for student response and behavior. With the realization that non-verbal communication can play such an importantrole in the process of education, there is a direct impetus to further examine this issue. Using this as a foundation forinvestigation, the current research considers the issue of non-verbal communication between students and teachers in thecontext of mitigating and managing conflict. By understanding these cues, educators can work to improve outcomes whenconflict arises with a student in the classroom.
