ABSTRACT:

This research is concerned with autoregressive integrated moving average (ARIMA) modelling of monthly crude oil exports of Nigeria. The realization covered is from January 2006 to November 2016. The time plot reveals an initial generally negative trend up to mid-2009, and then a positive trend up to mid-2010 and then a negative trend up to 2016.  An examination of the data reveals a measure of twelve monthly seasonality.  The Augmented Dickey Fuller (ADF) Test adjudges the series as stationary but its autocorrelation structure shows the involvement of a secular trend in the series. This means that the series is still non-stationary.  A non-seasonal differencing makes the series stationary.   The correlation structure of these first differences suggest an ARIMA(1,1,1) fit.  A twelve monthly differencing of the original series was done also.  The correlogram of these seasonal differences shows evidence of secular trend in them. A non-seasonal differencing rids the seasonal differences of the trend. The autocorrelation structure of the resultant series gives evidence of twelve-monthly seasonality and suggests a SARIMA(1,1,0)x(0,1,1)₁₂ fit.  However it is observed that on the basis of AIC, the ARIMA(1,1,1) fit is the more adequate model. Hence, forecasting or simulation of the export series may be done on its basis.

ABSTRACT

The Technical Trade Motor Vehicle Mechanics Works is noted to be very important to man considering the importance of transportation of goods and services. As such concerted efforts are being made by institutions in ensuring success in the teaching and learning of the trade. Despite this, there is evidently poor academic achievement and declining interest of students in the trade. This is largely blamed on ineffective teaching methods adopted by teachers and negative attitudes of students amongst other factors. The purpose of this study therefore is to determine the effects of multimedia lesson presentation on the achievement of students in Science and Technical Colleges. Two research question and two hypotheses were formulated for the study. A quasi-experimental research design was used. The sample was made up of 105 SSII students. The experimental group was made up 52 students (46 males and 6 females) while the control group had 51 students (46 males and 5 females). A Motor Vehicle Mechanics Work Achievement Test (MVMWAT) was designed and used by the researcher to generate data. Data collected was analyzed using mean and standard deviation to answer research question and analysis of covariance (ANCOVA) to test the hypothesis. The result showed that multimedia presentation as a teaching method enhances the achievement of students. There was no significant difference between the achievement of male and female students. The study therefore, recommended the use of multimedia as a teaching strategy to boost academic achievement of students in the trade as well as related technology subjects. The massive use of computer aided instructions should be encouraged in the teaching and learning process in MVMW.

ABSTRACT

Teaching and learning in the 21^st century, an ICT- driven age is undergoing innovations as a result of the changing demands in the education enterprise. Classrooms have become more inclusive with respect to the diverse needs of gender, cultural and individual differences. Also classrooms have become largely ICT integrated and the norm is towards effective use of ICT materials to enhance teaching and learning. Emphasis, therefore in this computerized age is on life-long learning and the learners are expected to do this using new technologies. These changing dynamics of classrooms situations have also made way for teachers and students to interact using various strategies. accordingly, emphasize is being laid on specific learning theories that are cognitively oriented, addressing, in teaching, new ways of preserving learning behaviors and learning strategies. This motivates teachers and trainers to make the test pedagogical use of ICT in their own teaching and to encourage the development of high quality digital teaching and learning materials. Teleconferencing, webhosting, videoconferencing etc. are example of ways by which ICT has extended human experience in learning.

ABSTRACT

The need for proper understanding of the trend of the Nigeria’s external reserves can not be over emphasized, as it would help the Central Bank of Nigeria (CBN) and the Federal Government of Nigeria to make policies that would grow her economy. In view of this, this paper attempts to identify and build a suitable and reliable Box-Jenkins model for modeling the Nigeria’s external reserves. Nigeria’s 34 years external reserve data from January, 1981 to December, 2014 was used to perform analysis in E-views. The ARIMA (4,1,0) model with the smallest AIC and BIC statistics was found to out-perform the ARIMA (4,1,1) model. This paper therefore proposes the ARIMA (4,1,0) model for forecasting Nigeria’s external reserves. Keywords: Time series, Box-Jenkins model, ARIMA, External Reserves
