ABSTRACT

The article offers an overview of the heterogeneous set of adverbial clauses with their characteristic inferential and distributional properties. Specifically, the paper aims at highlighting the patterns and usage of adverbial clauses in Agatu as well as providing a framework for the study and analysis of adverbials of the language. This study is born out of careful observation of the importance of adverbials and the near absence of research work on the topic as it concerns Agatu. Introspective method, unstructured interview and some personal one on one chat with the native speakers of Agatu are the methods used. Some subjects who are native speakers of Agatu and are also speakers of English were chosen to serve as informants. They were required to translate some adverbials from English to Agatu. The analysis of the data is based on the various levels of adverbials such as; simple, compound, adverbial phrase, clause, forms and type are discussed in the language. Sufficient examples are given on adverbials and their differences which is the major concern of this paper. Adverbial paradigms in Agatu have shown that there are morphological processes. The main method of forming majority of derivational adverbs is by reduplication and negative marker of which new adverbs are created from adjectives. Forming open class adverbs from adjectives in Agatu is however unstable. It is also noticed in Agatu that some adverbs are formed without the addition of prefix or suffix, yet, exhibit the minor and major method of adverbial formation. Suffixation, spittoon as well as embedding are used in Agatu for the formation of compound adverbials. Many simple adverbs in Agatu denote position and direction. Adverbial clauses in Agatu have various means of expressing locative, temporal and indeed all kinds of other circumstantial information. The clause can be regarded as having the function of adjunct in sentence; though in this case it is a matter of embedding one clause in another clause. This research is expected to fill the existing vacuum in the study of Agatu syntax, add to linguistic research findings and, therefore stimulates further research of similar or wider dimensions in related fields in order to facilitate better and more productive language learning.

Abstract

This paper examined the effect of Crossword-Picture Puzzle (CPP) Teaching Strategy and gender on students’ achievement in Basic Science. A pretest-posttest quasi experimental design was employed. The sample consisted of 389 JSS II Basic Science Students from nine schools randomly selected in three States in Southwestern Nigeria. Three instruments used were-Teachers’ Instructional Guides for: Crossword-Picture Puzzle Teaching Strategy (r=0.76), Conventional Lecture Method (r=0.74); Basic Science Students’ Achievement Test (r=0.70).Three hypotheses were tested at 0.05 level of significance. Data were analysed using ANCOVA and mean scores. Results showed that treatment had significant main effect on achievement score (F (2,389) =202.16; p< 0.05; ᵑ2=.52). Gender had significant main effect on achievement score (F (1, 389) =3.99; p<0.05; ᵑ2=.01). The two-way interaction effect of treatment and gender was not significant on achievement score (F (2,389) =.980; p>.05; 2=.005).Crossword-picture puzzle strategy is therefore, recommended to be adopted by Basic Science teachers and curriculum planners.

ABSTRACT

The traditional instructional strategy employed by most biology teachers in teaching Biology concept has resulted in low learning outcomes. There is need to employ strategies such as guided discovery and self learning, particularly, among secondary schools students. The two strategies have been proved in literature to have exposed students to a better response to life changes in the real world; needed in alleviating the problem of low students’ achievement in biology, but they have not been adopted in the teaching of biology concepts. This study, therefore, examined the effects of guided discovery (GD) and self-learning (SL) strategies on senior secondary school students’ achievement in biology. The pretest-posttest control group quasi-experimental design with 3x2x2 factorial matrix was adopted. Two hundred and forty (240) SS2 students from six purposively selected senior secondary schools in two local government areas of Oyo State were used for the study. The schools were randomly assigned to experimental (GD and SL) and control (CS) groups and the study lasted for fourteen weeks. Six instruments used were: Teachers Instructional Guides for teachers using the two treatments and control group; Students Environmental Achievement Test (r=0.80), Cognitive Style Test (test-retest r=0.81) and Assessment Sheet for evaluating research assistants. Three null hypotheses were tested at 0.05 level of significance. Data were analysed using ANCOVA and Scheffe post hoc test. Treatment had significant main effect on students’ achievement score (F(2,227) = 197.804; p < 0.05). SL enhanced achievement scores (  =14.59) than GD (  = 14.20) and CS (  = 12.53). Self learning and guided discovery strategies improved students’ achievement in biology. It is, therefore, recommended that teachers, curriculum developers and textbook writers adopt these two strategies for the improvement of students learning outcomes in biology.

ABSTRACT

Frequently, in the academia and in other enlightened circles there are discourses, treatises and debates on the falling standard of education in Nigeria, especially when comparing the colonial / immediate post colonial era on one hand with the early 1990s to the present day period on the other hand. There seems to be a general consensus that the standard has fallen and it is still falling, what is however a source of discordance are the factors that have led to this trend. This paper is a contribution to the discourse by contributing a concept that has the potential of reversing this ugly trend. The “Student Domain Concept” is an idea enunciated by this paper that relates to what the architecture student can and should do within his/her sphere of influence, control or jurisdiction with respect to enhancing good academic performance. The special nature of architectural education was underscored and compared with some other professional courses. Aspects of attitudes to life and approach to architectural studies that inhibit or enhance good performance were examined. It is hoped that the application of the provisions of this study and recommendations by the student of architecture will put him / her in good stead to not only perform well academically but also be instrumental in reversing the ugly downward trend in Architectural Education.

ABSTRACT

Many countries have a national curriculum and these often leave little scope for schools to decide their own educational aims. Institutions may be left with the residual task of interpreting external imperatives rather than determining aims on the basis of their own assessment of student need. Except adequate and the right type of education be provided for the Nigerian populace, especially the youths and children, unemployment will always remain the bedrock of Nigeria’s turn around to backwardness. This paper addresses the fact that for the Nigeria education to impact on the society particularly the employers of labour, Educational Management Development must be encouraged i.e. Empowering educational institutions to enrich the already existing curriculum by providing regulatory bodies.

ABSTRACT: This work focused on the transesterification of Hura crepitans oil and the determination of the suitability of the oil and its ethyl ester to power a diesel engine. Hura crepitans oil was transesterified in a two step transesterification process using ethanol and potassium hydroxide to produce ethyl ester (biodiesel). The fuel properties of Hura crepitans oil and its ethyl ester were determined and compared with that of Automotive Gas Oil (AGO). The results showed that the biodiesel yield was 80.5% after transesterification. The flash point, cloud point, pour point, specific gravity at 15 oC, viscosity at 40 oC, heating value, acid value, ash content, sulphur content, free fatty acid, peroxide value, iodine value and pH of the oil was obtained as 72.60 oC, 7.40 oC, 3.12 oC, 0.864, 2.870 mm2/s, 48.90 MJ/I, 19.074 MgKOH/g, 0.104%, 30.75%, 0.9588, 0.061 Meq/KOH, 0.940 wijis and 3.50 respectively. The fuel properties of Hura crepitans biodiesel were obtained as follows; specific gravity at 15 oC was 0.884, viscosity at 40 oC was 3.420 mm2/s, acid value was 6.732 mgKOH/g, peroxide value was 0.021 Meq/KOH, Sulphur content was 8.74%, cloud point was 75.10 oC, flash point was 94.60 oC, free fatty acid was 0.3304, pH was 3.30, heating value was 38.74 MJ/I. The result showed that Hura crepitans biodiesel can be used to power a compression ignition engine.

ABSTRACT: In order to guide management in making better decisions, decorous project decision-making require risk management and risk analysis techniques be applied. As a result of uncertainty as well as hazard there are risks inherent in all engineering projects. Decision making under uncertainty literally encompasses every aspect of engineering projects. No project is risk free. Risk can be managed, minimised, shared, transferred or accepted; it cannot be ignored (Sir Michael Latham, 1994). Risks are assessed against criteria defined before or during risk analysis and ranking. Once ranked, the risks are almost easily displayed on a likelihood impact-matrix that serves as a clear communication tool, allowing everyone to be able to understand the level of risk. Risk management processes described include risk planning, identification, analysis, response and monitoring. If implemented correctly, a successful risk mitigation strategy should reduce negative impacts. The purpose of this paper is to describe the risk management process and why it is important to determine and quantify the risk involved in any project or venture. Such that decisions can be made to counter or mitigate and make allowances for potential detrimental events.

ABSTRACT: An existing pedal driven seed drill was test run, the problem with the low level of performance was studied, and modifications were made on the existing pedal driven seed drill for better performance. The angle of repose was used to calculate the volume of the seed hopper, shaft design of the solid agitator, diameter of both the front and rear wheel and the length of chain were calculated. The newly fabricated seed drill was calibrated and tested on the field using paddy rice and sorghum. The results of the calibration shows a seed discharge rate of 43.24 kg/ha for paddy rice and 432.2 kg/ha for sorghum. The speed, theoretical and effective field capacity were calculated to be 1.89 km/h, 0.174 ha/h, and 0.086084 ha/hr. The efficiency of the machine was evaluated to be 49.5 %. The seed drill has a seeding rate of 43.24 kg/ha.

 E-mail: abdikkozabi@gmail.com ABSTRACT: This paper presents the study of the effective Hamiltonian parameters (g1, g2, A1, A2) and the observed g and A tensors of the derivative axial and orthorhombic Jahn-Teller EPR spectra of Cu2+ in Cd2(NH4)2(SO4)3 single crystals at different temperatures. The variations of these parameters with temperature in the three mutually perpendicular planes of the crystal confirm axial symmetry for T>Tc and orthorhombic symmetry for T<Tc in this system. The simultaneous axial and anisotropic symmetries of the spectra owe their origin to the behaviour of Cu2+ ions in the three JT potential wells because they can undergo reorientation from one well to another or quantum tunnelling among them which depends on temperature, burial height or thickness and energy of the ions. The results show that the components of the activation energy and Fermi-contact parameter increase with temperature while the decrease of the anisotropy parameter (u) is more than it compensates for the slight increase in the effective Hamiltonian parameters g1 and g2 with temperature
