ABSTRACT

 

The study was carried out to determine the effect of suggestopedia instructional technique on academic achievement, interest and retention of metal work students of technical colleges. Six research questions were answered while nine null hypotheses formulated were tested at 0.05 level of significance. The study adopted quasi experimental design and was carried out in Lagos State. The population for the study was 410 male and female students. The sample size for the study was 114 metalwork second year students which comprised 72 males and 42 females randomly selected from two technical colleges. The instruments for data collection were metalwork cognitive achievement test and metalwork interest inventory. To ensure content validity of the metalwork cognitive achievement test (MWCAT), a test blue print (Table of Specifications) was built for the test. The, MWCAT, metalwork technology interest inventory, suggestopedia instructional technique, metalwork technology lesson plan and the training plans for metalwork technology teachers and students were subjected to face validation by three experts. The MWCAT was trial tested for the purpose of determining the psychometric indices of the test. A total of 40 items of the MWCAT had good difficulty, discrimination and distractor indices. In addition to face -validation, the metalwork interest inventory was also subjected to construct validation using factor analysis. Out of 62 items, a total of 40 items were finally selected for the interest inventory. The Kuder Richardson 20 (K-R20) was employed for determining the reliability of the metalwork cognitive achievement test while Cronbach alpha reliability method was used  to determine the internal consistency of the metalwork interest inventory and 0.82 was obtained. The data collected were analyzed using Mean, to answer the research questions while analysis of covariance (ANCOVA) was used to test the nine hypotheses formulated. The study found out that students taught metalwork with suggestopedia had a higher mean achievement score than those students taught using traditional teaching method in the achievement test, it was also found that students taught metalwork with suggestopedia had a higher mean interest score than those students taught using traditional teaching method in the interest inventory items and students taught metalwork with suggestopedia had a higher mean score than those students taught using the traditional teaching method in the test for retention of learning. There was a significant difference between the mean achievement scores of students taught with suggestopedia instruction technique and those taught with traditional method in metalwork. It was recommended that metalwork teachers in technical colleges should adopt the use of the suggestopedia instructional technique to teach metalwork trades to students. It was also recommended that facilities that could encourage the use of suggestopedia should be provided to metalwork teachers in technical colleges.

 

CHAPTER ONE

INTRODUCTION

Background of the Study

Metalwork has become a major essential technical trade in the curriculum of technical colleges in Nigeria. Metalwork technology is included into the curriculum of technical colleges to equip students with skills, knowledge and attitudes in welding and fabrication, foundry, forging, casting, riveting and machine shop practice. Metalwork technology according to Miller (2006) is the science and technology involved in the practice of metalwork trades. Shirley (2000) described metal work as the process of working with metals to create individual parts, assemblies or large scale structures. Metalwork technology in technical college therefore covers activities in welding and fabrication, foundry, forging, casting, riveting and machine shop practice. Fabrication pertains to working with sheet metals to produce articles like funnels, watering cans, containers of beverages, among others while welding deals with the joining of two or more metals together with the aid of heat and welding rod. Foundry concerns with melting and casting of metals into different shapes and sizes.

There is hardly any human activity where metalwork technology has not made impact. It is the art and act of using metals to produce useful products. Metalwork technology is one of the programmes of vocational and technical education. Acknowledging the importance of vocational education in the development of any society, United Nations Educational, Scientific and Cultural Organization (UNESCO) and International Labour Organization (ILO) (2002), recommended that all technical and vocational education (TVE) system in the 21st century should be geared towards lifelong learning. The expansion of learning opportunities in the world today has brought the need for a more robust instruction in education that requires critical thinking skills as well as technical competency to update necessary knowledge and applied skills in order to promote effective learning. Poisson (2000) stated that schools should, in addition to academic skills, inculcate workplace skills such as creativity; problem solving; collaborative skills and higher order thinking skills, in order to increase the students’ flexibility and job mobility. Hallak and Poisson (2000) stated that, this makes the students acceptable to the present and envisaged changes. In this context, Rojewskin (2002) noted that a shift from teacher-centred instruction to learner-centred instruction is needed to enable students acquire the new 21st century knowledge and skills. These challenges, therefore, necessitate a shift from traditional methods of teaching to modern teaching methods of which the Suggestopedia Instructional Technique (SIT) is one of them.
