dc.description.abstract For over two decades now, the Technology Acceptance Model (TAM) has been dominant in Information Systems (IS) research. However, in recent years, TAM has been criticized by IS researchers due to a number of shortcomings. Therefore, this paper points to the overemphasis of parsimony in TAM that severely limits its completeness and dynamism, and hence this paper presents a more complete and dynamic technology acceptance model (DTAM) for the purpose of providing a foundation for a paradigm shift. Unlike preceding TAM, TAM 2, and TAM 3 models that are based on the organizationalindividual- technological variable construction, DTAM is based on four categories of variables, namely; environmentalorganizational- individual- technological. Drawing on prior work in information systems, and using a triangulation method on the key theorization and findings of ten closely related theoretical paradigms, this study used a descriptive research design and a cross-section survey methodology. It developed a Dynamic Technology Acceptance Model (DTAM), which is more complete, coherent and unified. Out of a population of 91,542 university students, a representative sample of 1092 student’s respondents from higher education institutions (HEI) were used to empirically test DTAM in the context of the ICT artefacts - internet, electronic mail, and learning management systems (LMS) acceptance. DTAM explained 72.7 percent of the students’ intention to accept ICTs, with good model fit (Normed x2=5, RMSEA=0.06, GFI=0.94, and AGFI=0.91). en_US
