DEVELOPMENT OF CAPACITY BUILDING MODULE FOR REFRIGERATION AND AIR-CONDITIONING TECHNOLOGISTS IN SOUTH-SOUTH NIGERIA (INDUSTRIAL RELATION AND PERSONNEL MANAGEMENT PROJECT TOPICS AND MATERIALS)

ABSTRACT

The purpose of the study was to develop capacity building modules for technologists in refrigeration and air-conditioning in south-south Nigeria. Specifically, the study determined the Objectives of the modules for the capacity building of refrigeration and air-condition technologists. Content of the modules for capacity building of refrigeration and air-condition technologists. Teaching strategies for capacity building of refrigeration and air-condition technologists. Training facilities for capacity building of refrigeration and air-condition technologists. Evaluation techniques for capacity building of refrigeration and air-condition technologist. Develop modules for capacity building of refrigeration and air-conditioning technologists. Try-out to validate the developed modules. Research and development design was used. Five research question and one Hypotheses was used. The total population of the study was 118 which comprised 14 teachers of refrigeration and air-conditioning, 34 technologist, 45 technicians, and 25 students of mechanical engineering used for try-out.

There was no sampling and purposive sampling technique was used. Two sets of instrument namely; questionnaire for the development of capacity building module for technologist in refrigeration and air-conditioning (QDCBMTRA) and Refrigeration and Air-conditioning Psychomotive Rating Scale (RAPRS) were subjected to validation by two specialist in Refrigeration and Air-conditioning industry and two lecturers in the university. Cronbach alpha was used to establish the reliability of the instrument which yielded 0.89 and Kendall concordance correlation was used to determine the reliability of (RAPRS) Data obtained from the administration of the instrument was analyzed using cut-off point of 3.5 for decision making. The information obtained was used for the development of the capacity building modules.

The developed modules were tried- out on 25 final year students of mechanical engineering in Federal Polytechnic, Offa. There was initial and final rating. The scores obtained was analyzed using ANCOVA at 0.05 level of significance to test the hypothesis The result obtained revealed that there was significance difference 0.05 level. The study recommended that National Board for Technical Education should set up curriculum review committee that will use the module content for modification of refrigeration and air-conditioning practical content. Federal Government should re-train polytechnics teachers and graduates of polytechnics for capacity building in refrigeration and air- conditioning using developed modules.

CHAPTER ONE

INTRODUCTION

Background of the Study

Refrigeration and air-conditioning is a vital technology needed for industrial development. The importance of refrigeration and air-conditioning is evident in domestic, commercial and industrial application. Fruits and vegetables are stored at a low temperature after harvest with the aid of refrigerator. Also beverages, as well as staple foods are commonly preserved using refrigerator. Air-conditioning has enhanced business and industrial productivity while adding to human comfort. Rajput (2010) stated that application of refrigeration and air-conditioning are found in ice making, transportation, industrial air-conditioning, comfort air-conditioning, chemical and related industries, medical, processed food products and beverages, oil refining and synthetic rubber manufacturing, manufacturing and treatment of metals and freezing of products.
