| Effect of 7E’s’s Constructivist Approach on Students’ Achievement in Electromagnetic Induction Topic in Senior Secondary School in Nigeria |
In recent years, the use of electromagnetism has gained more importance in modern technology due to its wide range of application in all-electric field and equipment. Research findings have consistently indicated that electromagnetism is one of the perceived difficult units in senior secondary school physics curriculum. This study investigated the effect of 7E’s’s constructivist approach on students’ achievement in electromagnetic induction topic in senior secondary schools in Rivers State, Nigeria. The study employed a quasi-experimental design. Specifically, it was a pre-test post-test non-equivalent control group design. Two schools were purposively selected from nine secondary schools in Gokana Local Government Area of Rivers State, Nigeria. Two intact classes were randomly selected from each school, making a total of four intact classes of 58 Senior Secondary Three (SS3) physics students. One research question and one hypothesis were posed and formulated respectively to guide the study. The instrument used in gathering the data for the study was; Electromagnetic Induction Achievement Test (EIAT). The face and content validities of the instrument were carried out by three experts in physics education. Equivalent form and test-retest methods of reliability were employed. A reliability coefficient of equivalence of 0.88 and a coefficient of stability of 0.85 was obtained using Pearson Product Moment Method of Correlation. Item analysis was done to determine the psychometric features of each test item. The research question was answered using a descriptive statistics of mean and the corresponding null hypothesis was tested using inferential statistics of t-test at p ≤ 0.05 level of significance respectively. Results from the study showed that the mean score of the experimental group was higher than the mean score of the control group. The study also revealed that there was statistically significant difference between the mean scores of those exposed to 7E’s’s constructivist approach and those exposed to the traditional method. Therefore, it was recommended that teachers should use 7E’s’s constructivist instructional model in teaching science subjects. Also, students should be engaged in an active process of learning such as minds-on, hands-on and discoveries, so that they discover and create knowledge themselves as well become independent problem solvers. |

| Electrical Machines Skills Needed by Polytechnic Graduates for Employment in Oil and Gas Industry in Niger-Delta, Nigeria |
The study was carried out to assess the skills required by polytechnic graduates for employment in the oil and gas industry in Nigeria's Niger-Delta region. A descriptive survey was used for the study, whose population comprised 1404 oil and gas industry workers in the Niger-Delta, Nigeria. Purposive sampling technique was used to select from the population, 27 electrical supervisors and 62 electrical graduates as the study sample. One research question and one hypothesis guided the study. A 35-item structured questionnaire designed by the researchers and titled “Electrical Design and Drafting Skills needed by Polytechnic Graduates Questionnaire (EDDSPGQ)” was used to collect information from the respondents. The EDDSPGQ was designed based on the 5-Likert Scale. The instrument was face and content-validated by two industry-based electrical supervisors and another expert in measurement and evaluation. The instrument’s reliability was established via the Cronbach alpha method, having yielded a coefficient of 0.83.A mean was used to answer the research question; standard deviation was used to ascertain homogeneity in the responses of the respondents; and a t-test was used to test the hypothesis at a 0.05 level of significance. The study reveals that electrical and electronic graduates need to develop skills in drafting point-point diagrams, control circuits of an automatic re-closure scheme, star-delta starters and three-phase line-in diagrams. Consequently, it was recommended, among others, that the Government should provide modern training facilities in polytechnics as well as make SIWES more effective for the quality skills development of engineering students in preparation for employment in the oil and gas industry in Nigeria upon graduation. |

| Development and Evaluation of Brick/Block Laying and Concreting (B/Bc) Instructional Video |
Brick/Blocklaying and Concreting (B/BC) is one of the trade at the National Technical Certificate (NTC) level in Nigeria which is obtainable at the technical colleges. The objectives of this trade have not been achieved due to the inadequate nature of materials and human resources for implementing its curriculum. In order to address the issue of lack of psychomotor skills amongst technical college graduates, an intervening measure is to develop and evaluate instructional video for teaching and learning B/BC. The purpose of this study is to develop and evaluate B/BC instructional video. Five (5) research questions guided the study. Forty (40) heads of department of B/BC were selected for the study. Primary data were collected using camera and its accessories, and the Province of Prince Edwards Island Department of Education DVD/Video Evaluation form. The data collected was analyzed using frequency count and mean. The results from the study revealed that the developed B/BC instruction.

| Enhancing Teachers’ Competence in the Use of Instructional Materials in Electronics Education in Senior Secondary Schools in Nigeria |
Technology is the touchstone of development and the field of electronics is considered important in the fast developing society. Through the teaching of electronics in secondary schools, students learn basic skills needed to manufacture, operate, maintain, install and repair electrical and electronic equipment. It therefore means that the transfer of these knowledge, skills and attitudes require instructional resources for effective and efficient skill acquisition. This paper therefore focused on enhancing the competence of electronics teachers in the utilization of instructional resources for effective electronics subject delivery which has been reported as lacking among secondary school technology teachers in Nigeria. Problems associated with the effective use of these instructional materials in secondary schools such as poor teachers’ professional knowledge and insufficient awareness of types of instructional materials for use in teaching different electronics contents, were high... |
