ABSTRACT

The study investigated the effects of dynamic geometry instructional programme on SS1 students’ performance and retention in geometry in Nasarawa State. Six research questions guided the study.  The design of the study was quasi-experimental, non-equivalent pre-test, post- test control group type. The population consisted of all the SS1 students in 13 local governments in Nasarawa State. The sample of the study comprised 210 SS1 students in six senior secondary schools using purposive sampling technique. Geometry Performance Test (GPT) with reliability coefficients of 0.84 was used for data collection. Mean and standard deviation were used to answer the research questions. The results showed that there is significant difference in mean performance scores and mean retention scores between the SS1 students taught geometry using dynamic geometry instructional programme and those taught using the conventional method. The results showed that there is no significant difference in the performance and retention of male and female students taught geometry with dynamic geometry instructional programme. Based on the findings of the study, it was recommended among others that awareness of the positive effects of dynamic geometry instructional programme on the performance and retention in geometry should be brought to the attention of school administrators.

ABSTRACT

Global trend of urbanization has changed considerably as the development on flood plain is evident in urban settlement. This is the case of Kaduna urban area. Kaduna urban area is divided into almost two equal halves by river Kaduna. The Master plan of the Kaduna designated floodplain along the river to avoid exposing the inhabitant of the area to flood vulnerability. Nevertheless, land use development has since taken over the designated area of the floodplain which is the thrust of the study. The study aims at analyzing the urban land uses components that had encroached into the flood plain with the view of making recommendation for improvement. The study uses GIS tool as a model to determine the spatial extent of encroachment into the floodplains of the River. The study divided the study area into catchment areas for easy assessment. At the end of the analysis, the study established that the rate and nature of urban land use encroachment into the floodplain is progressive in nature. The average encroachment rate into the designated area was established at 49.9Km² which represents 40.92% of the total land areas designated as flood plain in 1967. Among the land uses that has encroached into the flood plain, residential land use has the highest encroachment level with 85.8% of the area encroached by it while others like industrial, educational and institutional land uses encroached 5.8%, 2.8% and 1.4% into the floodplain respectively. The lowest encroached land use into the area is the commercial, infrastructure and recreational land uses with 0.1%, 0.2% and 1.2% respectively. Based on these established facts, the following recommendations were given; there should be relocation of the inhabitant of the land uses to avoid risk of flood vulnerability; there should be effective policy integration and implementation of all urban management agencies responsible for physical development in Kaduna metropolis to avoid further encroachment into the floodplain; there should be land acquisition of all encroached and un-encroached area of the flood plain by the state government so as to regulate the area; there should be the creation of floodplain Buffer Zone to outline detail profiling of the existing built up area and the existing land use encroachment in the floodplain of the area; and land in safe and accessible locations should be supply to meet the needs of all sectors of the society to avoid further encroachment into the floodplain;

ABSTRACT

The real (inflation adjusted) gross domestic product of Nigeria is studied here by Principal Component Method. A realization of the series from the first quarter of 2018 to the third quarter of 2019 is analyzed using minitab 17 software. Both the correlation matrix and the covariance matrix are used. Eigen analysis of both matrices suggest that the first three principal components are enough to explain variation in the data set. The correlation principal components involved all the items. The covariance principal components did not involve all the items which is a deficiency. For example, livestock, forestry, fishing, solid minerals, construction, transport, utilities, accommodation and food services, finance and insurance, professional scientific & technical services, administrative and support services and business services, public administration, human health and social services and arts, entertainment and recreation are not involved.  This makes the method inferior.

ABSTRACT

In this research, an evaluation of the relationship between finite and infinite leg models variable were considered using ARMA approach. The method made use of descriptive statistics, augmented dickey fuller test, histogram, and correlogram techniques to check the presence of least significant values in order to select and fit the best model. The statistical Software packages used are Microsoft Excel and Eviews 8 version. The assessment criteria for the analysis were based on the ARMA test approach with Akaike Information Criterions (AIC) and Schwarz Information Criterions (SIC) measures to select the least significant value and to make decision.

ABSTRACT

The study has been obtained theoretical that demonstrated the neutron-rich fragments are also produced in the deep inelastic transfer reactions occurring in the region between Coulomb barrier and Fermi energy regime. It has been achieved the applicability of multi-fragmentation in the transition region between Coulomb barrier and Fermi energy regime. The goal of this paper is to achieve the theoretical prediction of mass distribution of fragment for  and . The theoretical reaction of   and  have been obtained. Collisions stages have been predicated. The results obtained are in agreement with the experimental data.
