A Comparative study of secondary school students’ performance in English and Social Studies in Junior Secondary Schools in Osun State, Nigeria

The study sought to ascertain the relationship between the performance of students in English language and Social Studies.  This was with a view of ensuring better performance in the two subjects.  The study employed the survey research design.  The population for the study consisted of all the Junior Senior Secondary School Students in Osun State, Nigeria. Stratified sampling technique was employed in selecting 800 students that were purposively selected in five local governments in Osun State using school types i.e. public and private schools, school locations i.e. rural and urban and gender i.e. male and female as stratum.  Two instruments were used to collect data for the study. They are: English Achievement Test (EAT) and Social Studies Achievement Test (SSAT).  The reliability of the instruments yielded 0.74 and 0.86 respectively using Cronbach alpha.  The instruments were analyzed using descriptive and t-test statistics.   The results showed that there is a significant difference in students’ performance in English and Social Studies (t=13.809, P<0.05).  Also, there is a significant difference in the performance in English and Social Studies across the 10 schools. (English X = 25.36, SD= 10.699; Social Studies X = 32.21, SD= 9.969).  However, other variables in the study were found not to be significant.  It is therefore recommended among others that there should be consistent training and retraining of teachers for functional educational system in Nigeria.  Opportunities should be given to teachers for professional training on their subject disciplines, teaching techniques and organizational techniques which could be achieved through workshops, seminars, internet browsing and extensive reading for personal development.

Petrophysical and rock physics analyses for characterization of complex sands in deepwater Niger delta, Nigeria

Characterization of complex sand reservoirs in deepwater of Niger Delta was carried out through petrophysical and rock physics evaluation of well log data from three wells. Petrophysical analysis to determine clay volume, porosity, lithologies and hydrocarbon saturation were made. Rock physics was studied in velocity-porosity plane to analyze the influence of depositional and diagenetic features on the reservoirs. Cross-plots of different elastic parameters, using linear regression and cluster analysis, were generated for lithologic and fluid fill identification and to differentiate between the hydrocarbon bearing sands, brine sands and shale. Variance attribute was extracted on seismic time slice in order to image the complex sand distribution in the area. Three reservoirs of turbidite origin were identified within the upper fan to lower fan area. Petrophysical results revealed gas bearing reservoir units with less than 20% shale volume and porosity of 25-31%. Lambda-Mu-Rho (LMR) cross-plots for the reservoirs show gas saturated data cloud and trend. Ratio-Difference (R-D) cluster analysis of elastic rock properties shows a distinct trend and data cloud that represents lithofacies units and fluid fills. The study concludes that the reservoirs simulated contact cement and friable models with properties that ranged from highly porous, well sorted and poorly consolidated sand to fairly sorted and highly cemented sands. The results provide a model that increases the possibility of finding reservoir sand, while mitigating the risk involved in finding hydrocarbons

PARENTAL STYLES AND UNDERGRADUATE STUDENTS’ PERFORMANCE IN THE USE OF ENGLISH IN A TERTIARY INSTITUTION IN ONDO STATE, NIGERIA

The study examined how parental styles adopted affect the performance of undergraduate students in Use of English. A descriptive survey design was employed. The population consisted of 840 undergraduate students from two faculties out of the three in the university. Four instruments were used for the study. Two research questions and one hypothesis resulted from the study. Majority of the parents at 401(47.7%) adopted permissive parental style on their undergraduate students while 59(7.0%), 320(38.1%) and 60(7.2%) of the parents utilized authoritarian, uninvolved and authoritative parental styles respectively on their undergraduate students in the study area. The study also indicated that many of the undergraduate students performed moderately in Use of English in the study area 451(53.7%) and parental styles significantly influence undergraduate students’ performance in Use of English at (χ² = 680.101, df = 6, p < 0.05). The study concluded that parental styles play a significant role in determining undergraduate academic performance in Use of English.  Article visualizations

Psycho-Socio Variables as Correlates of Junior Secondary School Students’ Self Efficacy in Social Studies in Southwestern, Nigeria

The study sought to establish the level of relationship between students’ self-efficacy in Social Studies and eight predictor variables (State, school location, school type, parent education, number of sibling per parent, family income and gender), it equally determined the combined contributions of the eight predictor variables to Social Studies self-efficacy and determined the individual contribution of each of the eight predictor variables to Social Studies self-efficacy. This was with a view of determining students’ future ability in Social Studies.  The study is a descriptive research of the correlational type.  The population for the study comprises of all Junior Secondary School Students in Southwestern, Nigeria.  The sample consisted of 600 JSS 3 students drawn from six geographical zones in Southwestern, Nigeria using stratified sampling technique. An instrument titled “Social Studies Self-Efficacy Scale” (SSSES) was used to collect data.  Three research questions were raised and answered.  Multiple Regression Analysis was employed in analyzing the results.  The results showed that all the identified eight psycho-socio variables with the exemption of state, have no significant relationship with students’ self-efficacy in Social Studies.  Based on the above findings, the study recommended that teachers should design evaluation model that will encourage better performance in learners in order to bring about their self-efficacy.

Transformation after Early Ecclesiastical Architecture in Nigeria (1845-1980)

Transformation in ecclesiastical architecture had always been noticed from its evolution as each epoch tried to express its own time. This study examined the characteristic factors that led to the transformations from the early period of ecclesiastical architecture in Nigeria to the second phase of its development. The study area was Lagos because it was the cradle of ecclesiastical architecture in Nigeria and its nature being one of the metropolitan cities in the world encouraged the spread of Christianity which is adjudged to be an urban phenomenon. Since the study was explorative and historic in nature, qualitative research methods were adopted. The findings showed that early Churches in Nigeria were established by foreign missionaries and the administration and construction of their church buildings including financing and supply of labour with materials depended largely on foreign input. The second phase witnessed indigenization of the foreign established Churches and the establishment of African Independent and Pentecostal ones. The patronage of local input in terms of labour force and supply of materials was becoming obvious

Fatigue Analysis of Steel Jacket Platform in Shallow Water Depth in the Gulf of Guinea

This work investigates the fatigue life of a steel jacket installed at a water depth of 22m in the Gulf of Guinea, both deterministic and spectral analysis was done using the Bentley SACS software. Wave data was collected every 3 hours for seven years resulting in 20440 sea states. The analysis was carried out using industry codes and standards for critical inspectable and non-inspectable members. The result of the analysis was obtained for 50 modal shapes, and the mass participation factors show the highest vibration at the mode shape of 2. The fatigue life of the joint was determined for a life of 50 years and applying the factor of safety of 5; the spectral analysis shows that none of the members investigated to meet the fatigue life of 250 years. However, the deterministic analysis shows some members that meet the fatigue life of 250 years. The analysis was also conducted for the piles both above and below the mud line, and the spectral and deterministic analysis show that the piles meet a fatigue life of 500 years using a factor of safety of 10. It was concluded and recommended that the joints on the jacket that do not meet the fatigue life should be rewelded and inspected for structural integrity. Also, the result shows that the spectral analysis is more detailed than the deterministic analysis.
