GRAVITATING TOWARDS TECHNOLOGY IN EDUCATION: PLACE OF MAKERSPACE
Get PDFBased on constructivist philosophy which focuses on enabling learners to generate knowledge through interaction with physical objects, the idea of makerspace was initiated. The main essence of makerspace is to stir creativity, innovations and motivate learners towards designing and inventing. This paper is an exposition on the place of makerspace as a new approach to pedagogical activities. The 21st century is immersed in information and communication technology revolution which has necessitated a new way of learning. New generation of learners are referred to as digital natives who are naturally gravitated towards new innovations. This paper relies on recent scholarly publications to point out intricacies of makerspace, the need for educators to embrace it, the new role for educators and other stakeholders in education and the need to manage this change in the educational system. The paper also points out the challenges that this new wave encounters in areas where adoption has taken place and the benefits of adopting makerspace. Conclusion is however made that change is constant and the idea of makerspace may be the new shift that will totally revolutionize the academic world. It is suggested that Faculty and Management need to encourage studies to evaluate accruable benefits of makerspace. Keywords: Makerspace, education, technology. STEM, learning process, learners
The Pragmatics of Political Deception on Facebook
Get PDFFacebook, an intrinsic part of 21st century social realities where cognitive-participatory activities are
largely captured, is consistently explored for political deception. This chapter investigates how participants
utilize language to deceive politically the Nigerian electorate on Facebook. For data, 250 Facebook posts
on Nigerian politics were sampled, out of which 50 were purposefully selected for being highly rich in
deceptive content in order to unpack online deception through multimodal critical discourse analysis.
Four deceptive forms—equivocation of identity, exaggeration of performance, falsification of corruption
cases, and concealment of offences—within two socio-political contexts—election and opposition—constituted the posts. These prompt an evocation of a messianic figure, blunt condemnation, and evocation
of sympathy and retrospection to achieve the political intentions of criticism, self-presentation, silent
opposition, and galvanizing public support. The chapter concludes that political propaganda taps into
Facebook users to appeal to their political biases and sway their opinions
BLENDED LEARNING IN HIGHER EDUCATION: IMPLICATION AND STRATEGIES FOR ACADEMIC LIBRARY SUPPORT
Get PDFFollowing advances and extensive use of information and communication technology (ICT) in education and the current tech savvy generation of learners in higher institutions of learning, blended learning is gaining popularity as it is adjudged effective in improving both teaching and learning process in higher institutions of learning. It has the potential to expand access to quality education and break learning barriers in developing countries. Blended learning has created a paradigm shift in library services, however, not all academic libraries in developing countries have understood their roles in blended learning environment. Academic library can play significant roles in collaboration with faculty. The paper examined innovative strategies that academic libraries can adopt to make effective use of blended. The paper examined the state of academic libraries in developing countries with emphasis on their ability to participate in an embedded learning environment, it revealed that traditional learning methods is still prevalent in many developing countries, the paper considered factors that enhance and hinder academic libraries intervention in a blended learning environment. Competencies and skills required by academic librarians to be relevant in an embedded learning environment were discussed. The paper proffered workable recommendation for implementing a blended learning environment. In conclusion, the paper recommends that librarians in developing countries must be intentional about skills acquisition so as to be well equipped to join their counterparts in other developed climes to play a significant and principal role in the ever dynamic sophisticated learning environment
Genetic Variations, Heritability and Genetic Advance Studies among Okra Accessions grown in different Agro-ecological Zones in Nigeria
Get PDFSome level of variation within crop varieties is highly important for its improvement
with the aids of good plant breeding methods. A field research experiment was carried
out with the aim to estimate genetic variation and heritability in the okra accessions
grown in different agro-ecological zones in Nigeria. Twenty okra accessions were
obtained from various locations in different agro-ecological zones of Nigeria. Twenty
okra accessions were evaluated between April to August 2018 at Ekiti State University
Teaching and Research Farm, Ekiti State. These twenty okra accessions constituted the
treatment, which was lied out in a RCBD in a three replicates. The result were highly
significant (p<0.01) for all the traits studied. Magnitude of the phenotypic coefficient
of variances were slightly higher than genotypic coefficient of variances in this study
which showed that environment did not much influence the estimates of genetic
performance. The coefficient of phenotypic and genotypic variances were high in the
traits studied. Heritability estimates ranges from 75.04% for days to 50% flowering
to 98.85% for weight of 100 seeds. High heritability with high genetic advance were
observed for all the studied traits indicating that they are governed by additive gene
action and this could be improved through simple selection except days to 50%
flowering with the lowest heritability value coupled with the lowest genetic advance
value lesser than 10%
Comparative Analysis of Selected Animal and Vegetable Oils Suitability in Machining of Plain Carbon Steels
Get PDFDue to the alarming rate in public awareness on environmental issues, there has been growing demand for biodegradable materials which has opened an avenue for using vegetable and animal oils as alternatives to petroleumbased polymeric materials in the market, most especially in machining operations. Thus, research on biodegradable functional fluids has emerged as one of the top priorities in lubrication, due to their applicability in many diverse areas. In this quest, there is need to conduct machining trials to determine the suitability of these oils in metal cutting (turning) operations of plain carbon steels. This study investigate the effect of the selected cutting fluids on certain parameters like machine removal rate (MRR), machining time, tool wear and spindle power consumption, etc. under different machining combination in turning operations of plain carbon steels obtained from universal steel Ikeja, Nigeria, using 150 x 10 HSS cutting tool. The selected oils purchased from Ogunpa market in Ibadan, Nigeria, were sieved to remove any foreign particles or dirt. The solution; water, based-oil, and emulsifier (to allow thorough mixing of water and oil without separation), were mix at an elevated temperature of 550C in a proportion 4:1:3. Experimental results clearly showed that Conventional cutting fluid might be replaced with Non-conventional cutting fluids (vegetable and animal based) as they give better performance. With slight modifications and deliberate but careful alterations in some of the components of such oils, even better performing cutting fluids could be obtained.Self-sponsore
Traditional Fermented Condiments Modulate Biochemical Indices in High Cholesterol Diet-Fed Rats
Get PDFHypercholesterolemia is implicated in cardiovascular diseases (CVD) and is identified
as a common cause of mortality in this degenerative condition. Hence, CVD management strategy
should include control of hypercholesterolemia. This study describes the effect of some legume
condiments on biochemical indices in hypercholesterolemia rat model. Adult male Wistar rats
were used for this study and hypercholesterolemia was induced by inclusion of 1% cholesterol in
the rat feed. The animals were divided into five groups containing six animals each and were fed
with diets supplemented with 16% fermented soybean, bambara groundnut and African locust
bean. The study lasted for 30 days after which plasma was analyzed for the lipid profile and liver
function marker enzymes and the liver tissue analyzed for malondialdehyde (MDA) content. Elevated
plasma total cholesterol, triglyceride, LDL-cholesterol, alanine aminotransferase, aspartate
transaminase, alkaline phosphatase and MDA content showed significant (p<0.05) reduction in
the rats fed with fermented legume condiment-supplemented diets, with a concomitant increase in
plasma HDL-cholesterol as compared with the hypercholesterolemia control rats. This study
revealed that fermented legume condiment-supplemented diets attenuate hypercholesterolemia
and protect the liver of the experimental rats from oxidative damage, with African locust bean
condiment displaying the best biological potential
Indigenous knowledge development as a way-out of unemployment in Nigeria: A case study of Ondo, Ekiti and Osun states
Get PDFIndigenous knowledge is otherwise known as African science and knowledge. It was
conceived, born, processed, disseminated but preserved through natural inheritance from
succeeding generations without written document. This study was done to discover the
various indigenous knowledge jobs available, the employment status, the challenges they
encounter and suggest what government can do to help. Out of four hundred and fifty
(450) copies of questionnaire that were distributed, four hundred and eighteen (418)
copies (92.9%) were returned with usable responses, while thirty two (32) copies (7.1%)
were not returned. Descriptive statistical method was applied for the study,
Questionnaire, and observations were the research instruments used for data gathering.
Data were analysed using the use of frequency counts and percentages method. Findings
revealed that indigenous knowledge is the pivot of Nigerian economy. If indigenous
knowledge is better funded by the three tiers of Nigerian government, it is capable of
reducing unemployment syndrome that besieged the country. The various levels of
government should intensify efforts to improve the adult literacy programme, public
orientation and enlightenment, accreditation of indigenous knowledge practitioners, grant
interest free loans and establish more indigenous knowledge skill acquisition centres

Cadmium (II) Adsorption from Aqueous Solutions Using Onion Skins
Get PDFStaff PublicationThe potential of onion skins for removal of aqueous Cd(II) was investigated. Onion skin
powder was chemically modified using thioglycolic acid to develop a suitable, low-cost, and
efficient adsorbent for the removal of Cd(II) from aqueous solutions. Influences of temperature,
contact time, initial concentration of Cd(II), adsorbent dosage, and pH on the removal of Cd(II)
were probed. Optimal adsorption conditions were found at pH 5 and 4, and at 60- and 30-min
equilibrium time for the modified and native onion skins, respectively. The equilibrium process
was well described by the Freundlich isotherm model. The maximum Cd(II) adsorption
capacities, from the Langmuir model, are 17.86 mg/g (modified) and 21.28 mg/g (native). The
adsorption process followed the mechanism of physisorption. Pseudo second-order rate equation
fitted the kinetic data better than the pseudo first-order rate equation for the two adsorbents.
Thermodynamic parameters, such as standard free energy change (ΔG°), standard enthalpy
change (ΔH°), and standard entropy change (ΔS°), were calculated for adsorption experimental
studies. The results showed that the adsorption of Cd(II) on native/unmodified and modified
onion skins was a feasible process and exothermic under the studied conditions. The Cd(II)
adsorbed was efficiently desorbed from adsorbent using 0.3 M HCl
