A research was carried out to create and verify an autotronic training module for students studying vehicle technology at polytechnics located in Southern Nigeria. The design used for the project was Research and Development (R&D). An observation has been made that the curriculum of polytechnics in Nigeria lacks sufficient substance on autotronics technology. As a result, lecturers have challenges in fully imparting the abilities that are essential for the professional world. Undoubtedly, there is now a disparity between the training that craftsmen receive and the skills that are demanded by industries. The research was carried out in the southern region of Nigeria. The research focused on a specific demographic of 1,443 respondents. All the lecturers teaching automobile technology were included in the study, and a purposive sampling technique was used to select 75 automobile technicians from the region. A grand total of 122 questionnaires were distributed to the respondents with the assistance of five research assistants, one hailing from each state. The researcher created an 86-item questionnaire called the Autotronic Training Module Questionnaire (ATMQ). The 5-point Likert scale includes answer alternatives such as Highly Appropriate (HA)-5, Appropriate (A)-4, Moderately Appropriate (MA)-3, Inappropriate (I)-2, and Highly Inappropriate (HI)-1, respectively. The tools (Questionnaire and Multiple Choice Questions) underwent face and content validity assessment by three (3) experts. The instrument's internal consistency was assessed using Cronbach Alpha reliability, resulting in a coefficient of .88. The collected data were analysed using the mean and standard deviation to address the study objectives. Additionally, the hypotheses were tested using Analysis of Covariance (ANCOVA). A criteria mean of 3.5 or above was considered 'acceptable', while anything below was considered 'inappropriate'. In addition, the F-calculated (F-cal) ratio was compared to the .05 probability level of significance for each hypothesis. If the F-ratio is lower than the .05 probability level of significance, the null hypothesis was rejected; otherwise, it was accepted. The research concluded that the goals, materials, training facilities, training method, instructors' activities, students' activities, and assessment procedures are suitable for incorporation into the autotronic training module in polytechnics in Southern Nigeria.

The study examined repositioning technical and vocational education and training for sustainable development of graduates in post covid-19 era in Rivers State. The study adopted a survey research design method. The population of the study covered one hundred and twelve (112) TVET lecturers in tertiary institutions in Rivers State. A purposive sampling technique was used to select 70 respondents (45 male and 25 female lecturers) from the entire population. The instrument used for data collection was a 22-items structured questionnaire tagged '

The study determined the digital electronics repair skills required of polytechnics students for accelerated economic development in Rivers State. The study sought to determine the laptop computer and liquid crystal display television repair skills required for accelerated economic development in Rivers State. Two research questions were posed and two null hypotheses were formulated at .05 level of significance to guide the study. The population of the study covered fifty-three (53) respondents in the department of electrical/electronic engineering (thirty-six (36) lecturers and seventeen (17) instructors) of the two (2) state-owned polytechnics in Rivers State namely; Benson Kenule Saro-Wiwa Polytechnic Bori and Captain Elechi Amadi Polytechnic Rumuola Port Harcourt Rivers State. The entire population was used as it was considered manageable in size. The instrument for data collection was a researchers' designed questionnaire having 30 question items. The questionnaire was tagged "Digital Electronic Repair Skills Questionnaire (DERSQ)". The instrument was designed on a 5-point likert scale and was assign an ordinal value such as; Strongly Agree (SA) = 5, Agree (A) = 4, Undecided (U) = 3, Disagree (D) = 2 and Strongly Disagree (SD) = 1 respectively. Face and content validity of the instrument was determined by three (3) experts; two (2) experts from the department of Electrical/Electronic Engineering, Benson Kenule Saro-Wiwa Polytechnic Bori and one (1) expert from the department of Industrial Technical Education (Electrical/Electronic Option), Ignatius Ajuru University of Education Port Harcourt in line with the purpose of the study while Cronbach Alpha was used to obtained a reliability coefficient of 0.66 on the instrument after a test re-test method that lasted for 14-days. Mean and standard deviation was used to answer the research questions while t-test was used to test the hypotheses. It was decided that mean scores less than 3.50 was regarded as disagree while mean scores equal or greater than 3.50 was regarded as agree respectively. The study found that digital electronic repairs skill of laptop computer and liquid crystal display television are required of polytechnic students for accelerated economic development in Rivers State. Recommendation reached amongst others is that government should encourage the collaboration of foreign electronic expert from the advanced countries into our polytechnic for the training of electronic technology and related practical.

The study employed a descriptive survey and was carried out in the four (4) technical colleges in Rivers State namely: Government Technical College Ahoada, Government Technical College Ele-Ogu, Government Technical CollegeTombia and Government Technical Collge Port Harcourt respectively. A structured questionnaire titled; Building Effective Manpower through Researching in TVET Programme in Nigeria (BEMTRTVETPN) was used to seek for responses. The instrument was face and content validated by three (3) experts in technical education and a coefficient of 0.94 was established using Pearson Product Moment Correlation (PPMC). The instrument items which was formulated on 5-point likert scale have Very High Extent (VHE) = 5, High Extent (HE) = 4, Moderate Extent (ME) = 3, Low Extent (LE) = 2 and Very Low Extent (VLE) = 1. Mean and standard deviation were used to answer the research questions whereas z-test was used to test the null hypotheses at 0.05 level of significant. The researchers decided that mean scores greater than 3.49 are accepted while alternating scores are rejected. The study therefore reveals that both respondents agreed with the two questions posed as significant to the development of manpower in Nigeria with an average mean scores of (3.95-4.00) for research question 1 and (3.65-3.68) for research question 2 respectively. Thus, the results showed that, there is no significance difference in the mean scores of respondents on the topic under study. Recommendation reached amongst others is; government and organizations should encourage researchers by reinstalling the necessary research facilities and provide research grants as often as possible.

The study investigated sex education as a tool for minimizing the risk of teenage pregnancy among secondary school students in Ogoni, Rivers State. The study used a descriptive survey. A structured questionnaire was used to elicit responses from the two (2) categories of respondents on the subject. Three (3) experts validated the research instrument and a reliability coefficient of 0.88 was established using Pearson Product Moment Correlation (PPMC) on a four (4) Points Modified Likert Scale such as; Strongly Agreed = 4, Agreed = 3, Disagreed = 2 and Strongly Disagreed = 1. Mean and standard deviation were used to answer the research questions whereas t-test was used to test null hypotheses at 0.05 level of significant. The study deduced that the respondents are not in agreement with the two questions posed as significant in minimizing the risk of teenage pregnancy in secondary schools in Ogoni. Hence, the results showed a significant difference in the mean scores of respondents on the topic under investigation. This means that in spite of the inculcation of sex education into secondary schools curriculum, the risk of teenage pregnancy is still high in Ogoni. Recommendation reached amongst others is that "sexuality education should not be limited to school students, but relevant agencies should consistently educate parents/guidance not to be shy in advising their children on sex education.

This study was designed to on the effect of mobile learning application on academic performance of students' in carpentry and joinery craft in technical colleges in Anambra State. The study adopted a quasi-experiment research design. Two research questions guided the study and two hypotheses were tested at .05 level of significance. The population for the study ninety-two (92) NTC II students of the five (5) technical colleges offering carpentry and joinery craft in Anambra State. The entire populati on was divided into two (2) equal groups (experimental and control group) of forty-six (46) students apart; one for mobile learning application and traditional method. The instrument "Carpentry and Joinery Craft Achievement Test (CJCAT)" one hundred (100) multiple choice standardized test questions adopted from National Busines s and Technical Education Board (NABTEB) past questions papers for the period of 2020-2022 by the researchers. The instrument was validated by three (3) experts. The Carpentry and Joinery Craft Achievement Test (CJCAT) was administered on fifteen (15) students of Government Technical Collage Port Harcourt. Kuder Richarson (K-R) 21 was used to test the internal consistency of the Woodwork Achievement Test (WAT) and the reliability coefficient of 0.92 was obtained. Data collected were analyzed using mean and standard deviation to answer the research questions and Analysis of Covariance (ANCOVA) was used to test the hypotheses at .05 level of significance with the aid of SP SS. The study found that carpentry and joinery craft students taught joint and jointing as well as scaffolding using mobile learning application performed better than those students taught using the traditional method of teaching which is indicated in the performance mean gain of the both group. Consequently, the researchers recommended among others that mobile learning application should be developed in all areas of carpentry and joinery craft and installed for students' utilization for bette r performance in technical colleges in Anambra State.
