Conceptual model for learning automobile transmission systems in Nigerian tertiary institutions offering automobile engineering course

Abstract

The experimental learning approach in Nigerian tertiary institutions offering Automobile Engineering (AE) faces criticism for various documented limitations and deficiencies in meeting with the desired expectations and in addressing the current challenges. The AE departments place less emphasis on Automobile Transmission Systems (ATS) due to apparent lack of conceptual model that can guide its implementation through Hausa medium of instruction. Hence, this research aims to develop a conceptual model for learning automobile transmission systems in Nigerian tertiary institutions offering AE course. Accordingly, the design of the research is applicable to determine ATS topics and their respective areas for the development of the model for successful learning of ATS in Nigeria. Quantitative research design, specifically non-equivalent controlled groups design, comprises the research basis. Three hundred and thirty one (331) participants, comprising 325 students and 6 AE experts underwent a selection process using a census sampling technique from three AE departments of three tertiary institutions in the Northeastern geopolitical zone of Nigeria. A researcher-made concept maps assessment test and structured questionnaire of four major topics of ATS that comprise the instruments used for data collection. The validation and reliability of the instruments proved satisfactory from the scrutiny of experts and pilot study assessments. Descriptive statistics, stepwise linear regression analysis and structural equation modelling proved suitable to analyze the research questions. The findings discovered a conceptual model for learning ATS in Nigerian tertiary institutions offering AE course that include gearbox, clutch propeller shaft and drive axle, which collectively comprise 19 areas of ATS. Therefore, the researcher recommends the implementation of the conceptual model in Nigerian tertiary institutions offering AE course for maximum understanding and successful application of the knowledge and skill learned in the subject.
