Effect of Teacher Constructed Furnace on Students’ Performance in Metal Work Technology in Technical Colleges in Rivers State.
Abstract
The purpose of this research was to determine the effect of teacher constructed furnace on students’ performance in metal work technology in technical colleges in Rivers state using four topics in metal work that require the use of furnace namely; heat treatment, soldering, forging and foundry.
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 were used for the study. The instrument for data collection was made up of Metal Work Achievement Test (MWAT) developed by the researcher.
The achievement test consists of 200-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 teacher constructed furnace and 200 multiple-choice test items.
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 four research questions and testing four hypotheses at 0.05 level of significance.

Introduction
Background of Study
The provision of quality technical education is the responsibility of the government to meet human resources needs of the nation in technology.
Quality technical education trainings are aimed at equipping the learners with useful skills and knowledge in their desired areas of study.
Technical Education programmes are provided for the learners to have opportunity to acquire the knowledge and manipulative skill for effective nation-building.
Technical education programme is conducted in Technical Colleges and other related institutions.
Nwachukwu (2006) defines technical education as that aspect of education, which leads to the acquisition of practical and applied skills as well as basic scientific knowledge.
Technical Education programme is offered in Technical Colleges and other related institutions.
Technical Colleges according to Okoro (2006) are vocational training institutions in Nigeria that admit junior secondary school leavers to senior secondary schools and provide them with a full vocational course of three years duration.
Technical Colleges sometimes admit students who have the First School Leaving Certificate and give them a full six years vocational training.
This later case occurs in a situation where the Technical College is experiencing difficulties in attracting enough junior secondary school leavers into its vocational programmes.
Technical Colleges are regarded as the principal vocational institutions in Nigeria. They give full vocational training intended to prepare students for entry into various occupations.
