The study adopted repeated measures two-group within-subject experimental research design. The research collected data in order to answer three research questions and test one hypothesis. The sample comprised 450 senior secondary II Physics students (male = 303 and female = 147) drawn from population of Physics students in Taraba State. Multi stage sampling technique was employed to randomly select twelve schools from three Local Government Areas of the three Senatorial Districts of Taraba State, and an intact arm of SS II from each of the sampled schools was used. Two parallel 40-items Physics Achievement Test developed by the researcher were used for data collection. The resulting data were collated and analysed using descriptive statistics and t-test. Results showed that reliability coefficients obtained from the two formats were quite comparable. However, the finding revealed that there is significant difference between the students mean achievement score in the format A and Format B of the physics achievement test (t = 4.409, df = 898, p < 0.05, two-tailed). Sequels to the findings, it is concluded that changes in item sequence has no effect on the reliability coefficients, but students will perform better in physics achievement test if the test items are arranged randomly than in descending order of difficulty.

available equal prospects for students with diverse needs. This is so because students enter school
with a wide scope of individual differences as a result of the multifaceted relationship between
unequal environmental situations and genetic dispositions. The diverse sets of socioemotional
characteristics and cognitive skills students entered formal school with determine how fast and how
well students will learn. The capacity of schools to manage student heterogeneity will influence the
provision of equal opportunities and the capacity to promote educational equity. Many existing or
proposed interventions of policymakers and educators fail because they do not account for a
learner’s contextual realities, such as structural and systemic barriers (poverty and marginalization).
So, educational outcomes remain unequal within and across nations. Students’ mindsets have
been acknowledged as a potential prise for making academic outcomes more equitable. Research
studies have identified two broad ways the mindset culture can be communicated by teachers. This
paper distinguishes between different notions of educational equity, reviews the empirical and
theoretical mindset culture and examines its potential to reduce group-based inequalities in
education.

A 40-item Physics Achievement Test was developed and administered to 600 senior secondary school two students, who were randomly selected from 12 senior secondary schools in Taraba State, Nigeria. Results showed that item statistics obtained from both frameworks were relatively similar. However, item statistics obtained from IRT 2-parameter model looked balanced than those from CTT. In addition, for item selection process, IRT 2parameter model retained more items than CTT model. This result implies that test developers and public examining bodies should integrate IRT model into their test development processes. Through IRT model, test constructors would be able to generate stable items than in the CTT model used at present and at the end, the test scores of examinees will be more reliably estimated.

Except students are convinced that their effort will yield the desired consequences, there is little or no enticement to engage in those actions. Can a student that feels hopeless in physics sustain his or her interest in Electrical Engineering? Human behaviour is influenced by factors that are embedded in the core belief that he/she has the capability to accomplish that behaviour. Little attention has been given to Self-efficacy in tertiary physics in Nigeria. This study adapted and validated (using EFA and CFA) a short Physics Self-Efficacy Questionnaire before administering it to three hundred and seven(307) first-year General Physics I students at the Federal University Wukari (= 157 = 150). Females reported lower self-efficacy than males. The finding revealed that there is a significant difference in Physics self efficacy as reported by male and female (t = 7.7711, df =305, p =0.0001, 2 tailed). The effect size is large (= 0.888). This study posited that gender is a factor to consider in the study of physics self-efficacy, and this may have far reaching effect on research on self-efficacy, and on teaching and learning of tertiary physics.

A quasi-experimental pre-test-post-test design was used. The study involved two student groups: the Experimental Group and the Control Group. While the control group did not receive formal teaching on problem-solving techniques, the experimental group did receive such training. Utilizing the Physics Achievement Test, data were gathered and analysed using descriptive statistics and ANCOVA. The findings show that providing clear guidance on how to solve problems improves students' achievement in physics. According to this study, providing clear instructions on problem solving was beneficial for both males and females. To improve students' achievement in Physics, physics teachers should provide clear guidance on problem solving to their students.

Two hypotheses were examined while the study was driven by two research questions. The study used pretest - posttest control group research design. 100 pupils were adopted for this study. Two secondary schools from the local government region were chosen at random, with one serving as the experimental group and the other as the control group. The study's target population was SS I students taking Physics in the identified schools. JiTT was used employed to for the experimental group while the control group was given the same information in a normal classroom situation. The Just-in-Time Physics Achievement Test (JiTTPAT), which comprises 20 multiple-choice questions was developed by the researchers on the topic of measurement of physical quantities, was used to gather data with reliability index of 0.76. Mean, standard deviation, and ANCOVA w...

Probe measurements are rapid, cheap and non destructive compared to other conventional methods of core analysis. Low sensitivity magnetic susceptibility probe, high sensitivity magnetic susceptibility probe and air minipermeameter probe measurements were carried out on 45feet of slabbed core obtained from a shoreface reservoir. The result from the measurements were analysed and compared. The magnetically derived illite content from both magnetic probes correlated with probe permeability. High illite content indicates low permeability and low illite content indicates high permeability. The low sensitivity magnetic probe was found to be better than the high sensitivity magnetic probe in terms of correlation of magnetically derived illite content with probe permeability. Carrying out two magnetic susceptibility measur...

Incessant building collapse and foundation failures in Nigeria have continued unabated in recent years, causing loss of lives and properties. The necessity for site characterization for construction purposes has therefore become vital so as to prevent loss of valuable lives and properties that always accompany such failure. The purpose of this study is to carry out Geo-electrical subsurface characterization for foundation purposes. The method employed in this study is the Vertical Electrical Sounding (VES) technique using the Schlumberger configuration. Ten (10) vertical electrical sounding points were conducted. The data obtained were interpreted by computer iteration process and results indicate a three (3) to four (4) layered lithology with the exception of VES 9 which has only two (2) layers. Different zones were delineated ...

In order to examine how structural deformation above mobile shale influences patterns of deposition, trap geometry, and their implications for petroleum accumulation, a comprehensive interpretation of a suite of 3D seismic data acquired over Makad field was carried out manually. Three sand tops namely AA-1, AA-7 and AA-L in the field were selected for interpretation based on good petrophysical parameters. The wells penetrated into the downthrown side of the major structural-building fault in the study area. The mapped horizon surfaces and fault were exported to base map and contoured, to generate fault plane maps and structure maps for the interpreted horizon. The trapping mechanism is fault assisted. The results of this study show that field conceptual deve...

Since resistivity method is based on the equation of conservation of charges and Ohm's law; the hydrodynamics on the equation of conservation of mass and Darcy's law, there is a need for combined effort to sharpen means of estimation, to improve confidence, based on the physics of the problem. By reviewing the extensive literature on this subject, some interesting results pointing out the presence of different physical behaviour controlling the relationship between hydraulic conductivity, K, and electrical resistivity, ρ are made known.

Key benefits of 4D seismic include optimising injector profile management, optimising well placement, defining barriers to flow or compartments, assessing zones of undrained and bypassed oil, all of which leads to cost effective increase in oil and gas production. Onshore oil fields in Nigeria should also have 4D seismic and more publications from companies operating in Nigeria is encouraged.
