Validating Measures of Technological Acceptance Model in the Context of Lecturers at Kyambogo University

Abstract

The study validated the measures of the Technological Acceptance Model (TAM) in the context of lecturers at Kyambogo University. Based on Davis (1986), the TAM was studied in terms of perceived usefulness, perceived ease of use and behavioural intention. In this correlational study that involved a sample of 195 lecturers at Kyambogo University, data were collected using a self-administered questionnaire. Descriptive statistics and structural equation modelling (SEM) using Smart PLS for partial least square structural equation modelling (PLS-SEM) were used to determine the presence of the three constructs of the TAM, namely perceived usefulness, perceived ease of use and behavioural intention. Descriptive results indicated that the above three constructs of the TAM were highly practised by lecturers at Kyambogo University. PLS-SEM showed that the indicators that were used to measure the above three constructs of TAM were appropriate measures. The study concluded that the indicators assessed in this article to measure the three constructs of TAM, namely, perceived usefulness, perceived ease of use and behavioural intention, are valid and reliable. It was recommended that researchers use the indicators assessed in this article to measure the three constructs of TAM.
