THE EFFECTS OF TEACHER CONSTRUCTED FURNACE ON STUDENTS’ PERFORMANCE IN HEAT TREATMENT IN TECHNICAL COLLEGES IN RIVERS STATE, NIGERIA

The purpose of this research was to determine the effect of an improvised furnace on students’ performance in heat treatment in technical colleges in Rivers State. The study adopted research and development incorporating quasi-experimental design. It involved the use of control group, pre-test – post test design. The population of 194 students from four technical colleges in Rivers State was used for the study. The instrument for data collection was made up of Heat Treatment Achievement Test (HTAT) developed by the researchers. The achievement test consists of 50-multiple choice items with four options of A-D. The test items were identified and selected from the content of (NABTEB) syllabus on metal work technology. Test re-test method was used to establish the reliability of the instrument; the tests yielded 0.70, 073 and 0.72, 0.74 for the first and second tests respectively. Four experts in metal work technology were involved in both face and content validity of the instrument. The results obtained from the test scores were compiled and analyzed using statistical tools such as; percentage, mean, and analysis of covariance (ANCOVA) in answering the research question and testing the hypothesis at 0.05 level of significance. Improvised furnace had positive effects on students’ performance in heat treatment with a mean gain of 4.61. The difference in performance between those taught using improvised furnace and those taught using conventional teaching aids was found to be significant at 0.05 levels of significance. Based on the findings of the study, the researcher recommended that government, technical college principals and the different agencies should provide fund to procure the materials and component for designing and constructing furnace by the teacher for teaching heat treatment in technical colleges in Rivers State. Also, constant power supply, generators, accumulators, anvil, steel vessel, pipes and electric blower should be provided and distributed by the ministry of education to the technical colleges for construction of furnace for effective teaching of in Rivers State. The industries, government, nongovernmental agencies and private enterprises and communities should provide components, consumable materials necessary for teaching heat treatment and supply the materials directly to the individual technical colleges in Rivers State

IMPROVISATION OF FURNACE FOR FORGING OPERATIONS IN TECHNICAL COLLEGES IN RIVERS STATE:IMPLICATION FOR VOCATIONAL COUNSELLING IN NIGERIA

The purpose of this research was to develop an improvised furnace to enhance students’ performance in forging operations in technical colleges in Rivers State. The study adopted research and development design. Forging is the art of shaping metals by hammering. Man has known this art since ancient times. Today machines have largely replaced the sweat and muscle of the blacksmith, who nevertheless remains indispensable for carrying out the jobs done by hand, necessary in steel and engineering works. The furnace was found to be valid for forging at 4.00 and reliable using steel with molybdenum at hardness of 164 HRC. Any temperature and harder having melting points above 8500c and 164 HRC respectively may be inserted directly into the flaming charcoal. The improvised furnace is a teaching material that is made up of a steel vessel hardened with carbon – molybdenum in the ratio of 0.20:0.68 percent respectively. It was lined with bricks and fired with charcoal, using an electric blower connected to a low voltage generator. This furnace was used to carry out various forging operations. Based on the findings of this study, the researchers recommended the government; technical college principals and relevant agencies should provide funds to procure the materials and components for designing and constructing these furnaces by the teacher for teaching forging in Technical Colleges in Rivers State. Also, constant power supply, generators, accumulators, anvils, steel vessels, pipes and electric blowers should be provided and distributed by the ministry of education to the Technical Colleges for construction of furnaces for effective teaching of forging in Rivers State. The industries, government, non-governmental agencies and private enterprises and communities should provide components and consumable materials necessary for teaching. These materials should be supplied directly to the individual Technical Colleges in Rivers State. Vocational counselors should guide students to take up occupation in forging

STRATEGIC HUMAN RESOURCE MANAGEMENT AND TRAINING METHODS FOR IMPLEMENTING OF VOCATIONAL EDUCATION PROGRAMMES IN TECHNICAL COLLEGES

The purpose of this study was to examine the strategic human resource management and its influence on vocational education programme in technical colleges in Rivers State. The study examined how management styles and in-service training of technical instructors influence vocational technical education programmes. Two research questions and two hypotheses guided the study. The descriptive survey was used and a structured questionnaire was used to elicit responses from the respondents. The population of the study was 200 students and technical instructors of the four technical colleges in Rivers State. A simple random sampling technique was used to obtain a sample size of 100 respondents. The instrument was sent to two experts for validity. A test-retest method was used to determine the reliability of the instrument. A reliability coefficient of 0.8 was obtained using Cronbach Alpha (). Results from the study revealed that participative, pace-setting and coaching management styles improved the standard of technical colleges. The in-service training of technical instructors offered the opportunity to acquire new skills and improve the performance of teachers in the classroom. It is therefore recommended that the participative, pacesetting and coaching management styles be practiced in technical colleges. Furthermore, there should be regular in-service training of technical instructors since this will improve the quality of vocational technical education programmes
