The study focused attention on the effectiveness of Computer Aided Instructions (CAI) on students’ performance in basic electricity in technical colleges in Rivers State. The study adopted the pretest posttest quasi experimental design method. The population of the study comprises of all the vocational I basic electricity students in the five technical colleges in Rivers State. They comprised of 93 students. Purposive sampling technique was used to select two Government Technical Colleges and a sample size of 60 students was randomly selected for the study. This sample size comprised of 30 males and 30 females. The research instrument used for the study was the Basic Electricity Test (BET). The instrument was validated by two lecturers from technical education department of IgnatusAjuru University of Education Port Harcourt. The reliability of the instrument was done using test-re-test method and Pearson’s product moment correlation was used to obtain a coefficient of 0.65. Two research questions were drawn and two hypotheses were formulated for the study at 0.05 level of significance. The data for the study were analyzed using Mean and Analysis of Covariance (ANCOVA). The result indicated that students taught using Computer Aided Instructions (CAI) performed significantly better than those taught using conventional method. Also, there was no significant difference in the post test performance scores of male and female students. Some recommendations were made from the findings.

The paper investigated the perceived influence of students’ demographic variables on their access to financial aids in public Universities in Rivers State, Nigeria. Six questions were formulated to guide the study and five hypotheses tested at 0.05 level of significance. The design adopted for the study was an analytical survey. The population of the study included 78, 216 students (34,997 male and 43,219 female) in the three public Universities in Rivers State. The sample of the study covered 791 students (Male= 395 and Female= 396) selected through the random sampling technique while Taro Yamane method of sample size determination was used for determining the sample size. The instruments used for collecting responses from students were questionnaire and a ten items interview schedule. The research questions were answered using frequency, percentage and cumulative percentage. Findings of the study revealed that students’ demographic variables have an influence on their access to financial aids in public Universities in Rivers State, Nigeria. The implication of this is that the government’s expenditure on education will continue to increase in the absence of these alternative financial aids in the public Universities in Rivers State, Nigeria.

The study investigated the effects of out-door activities on students’ attitude towards learning of Physics in Senior Secondary School Physics in Ekiti State, Nigeria. The research design adopted in the study was Pretest-Posttest Quasi-experimental. The sample for the study was 150 Senior Secondary One (SSI) Physics students (this sample was divided into the experimental and control groups in ratio 1: 1 i.e. 75 in each group), selected through the multistage sampling technique from a total population of 7,852 SS I students offering Physics in all the 184 public Senior Secondary Schools in Ekiti State. The instrument used to collect relevant data from the subjects was Physics Attitudinal Scale (PAS). The reliability of the instrument was determined through the split-half method with the reliability coefficient of 0.83. Two null hypotheses were tested at 0.05 level of significance. The data collected were analysed using inferential statistics of t-test and Analysis of Covariance (ANCOVA). The results of the analyses showed that there was significant difference in the attitude of students to Physics in the experimental and control groups in favour of experimental group. Based on the findings of the study, it was recommended that non-conventional teaching approaches such as using out-door activities, should be introduced into the teaching of Physics in the nation’s secondary schools to reinforce the hitherto adopted conventional teaching method and Physics teachers should be encouraged to make use of these new teaching approaches.

SummaryIn a cross-national comparison of the frequency of occurrence of various diagnoses among elderly psychiatric patients admitted to public mental hospitals in London and New York, a short battery of psychological tests was administered to all patients independently of psychiatric examination. The psychological assessment was focused on the differentiation between dementing and affective disorders. The test performance showed a highly significant difference between the two groups as diagnosed, and when patients were allocated to groups on the basis of tests alone these allocations showed a high rate of agreement with initial psychiatric diagnosis. There was a similar high rate of agreement between test allocation and hospital diagnosis in the U.K., but this was not so in the U.S.No significant differences were found between the test performance of U.K. and U.S. patients, except on the WAIS Vocabulary and the Angles Error measurement of the Bender-Gestalt test. When the effects of age and Vocabulary score were eliminated these differences disappeared.The hypothesis that the diagnosis of affective disorder would be confirmed by a relatively greater improvement in test performance over time in this group of patients was not upheld by the non-parametric analysis of change scores. However, an analysis of covariance utilizing age and initial score did indicate the expected differential improvement.

The aim of this paper was to examine community perspective to petroleum exploitation and pollution in Ogoni, Rivers State. To achieve this aim, the objective was to determine the extent to which the pollution of the environment has affected the people’s views of usefulness of the resources in their communities. The survey design method was employed. Purposive sampling technique was used to select 21 oil bearing communities from the four Local Government Areas (LGAs) of Ogoniland. The data were collected using interviews, focus group discussions, oral testimonies and questionnaires. Being qualitative; transcriptions, rewriting and coding were employed in data analysis, except for the questionnaires which adopted descriptive statistical methods. Results showed that majority of the people have not benefitted from the petroleum resources in their communities. It was revealed that pollution has changed the people’s views of the usefulness of petroleum resources, as they clearly see the resources in their communities as a curse. However, many communities believed that there was no sincerity on the part of their leaders, as the dividends claimed to be given by the multinational oil companies (MNOCs) for the welfare and benefit of the people were not visible. It is recommended that in order to change the perception of the people toward petroleum exploitation, the MNOCs should massively develop the host communities with basic social amenities and deal directly with the land owners whose portions of land are directly affected and not through the chiefs or the Community Based Organisations (CBOs).

The study examined effect of constructivist strategy on students Achievement in Senior Secondary Mathematics in Rivers State. The research was guided by three research questions and corresponding hypotheses. The population is all the thirty four thousand, one hundred and sixty eight (34,168) of all Senior secondary II (SS11) students in Rivers State during the 2018/2019 Academic year. A sample size of 280 students in four intact classes were selected through purposive sampling technique. Two of each of the classes were used as experimental and control groups. Non randomized pre-test, post test control group design was used for the study. Instrument used for the study was Mathematics Achievement Test (MAT) made up of 25 items drawn from simple statistics and Lesson Packages. The instrument was validated by experts and reliability coefficient of the instrument was obtained through test-retest method. The scores obtained were subjected to Pearson product moment correlation coefficient analysis and the result yielded 0.82. Analysis of Covariance (ANCOVA), Mean and Multiple Classification Analysis  (MCA) were used in analyzing the data. Findings reveals that constructivist strategy was more effective in facilitating students achievement in Mathematics than expository method. The result did not show a significant difference in students’ achievement in Mathematics in terms of gender and school type. The study therefore recommended among others the use of constructivist strategy in the teaching and learning of Mathematics in schools.

The study determined the effects of mentoring enhanced strategy on secondary school students’  self-regulation (SR) in physics in education zone ‘C’ of Benue State, Nigeria. The study was guided by two research questions while two hypotheses were formulated and tested at 0.05 level of significance. The design of the study was the quasi-experimental, non-randomized, pre-test and post-test control groups. The population of the study consisted of 4,064 SS Two physics students in the 94 schools in Education Zone C. The sample comprised 406 SS Two physics students drawn from 10 schools using multi-stage sampling technique. The research instrument adapted and used for data collection was Students’ Self-Regulation Scale (SSRS). The research instruments was subjected to a reliability analysis using Cronbach’s Alpha Formula which yielded a reliability co-efficient of 0.85. Data collected were analyzed using descriptive statistics of mean and standard deviation to answer the research questions while inferential statistics of Analysis of Covariance (ANCOVA) was used to test the hypotheses. The findings revealed that students who were exposed to mentoring exhibited higher self-regulation levels (P = 0.007 ˂ 0.05) than those students who were not exposed to mentoring. There was no significant difference between male and female students’ self-regulation level (P = 0.036 ˃ 0.05). Based on these findings, it was recommended among others that the use of mentoring enhanced strategy should be encouraged and used in physics instruction in secondary schools.
