The article is devoted to the role of a priori information on the basis of a meta- -analysis in the evaluation of the fit and accuracy of Technology Acceptance Model (TAM). This type of model is particularly used to analyze the attitudes and behavior towards new technologies (Moodle platform). In model construction three approaches are compared: structural model with the latent variables (SEM), Bayesian SEM with informative priors based on metanalysis. The aim of the paper is to assess the role of information a priori (subjective knowledge of the researcher and the results of past studies) to assess the stability of the model parameters and fit of the model. Use of information about the prior distributions of parameters and values of point estimates allows to determine the starting points of estimation process and is an essential condition for building a model in bayesian approach. In the process of modeling two models are compared: one built solely on the basis of data (without prior information) and the other that use subjective knowledge of the researcher.
Background and Purpose - IBM SPSS Statistics is among the most widely used programs for statistical analysis in social sciences. Due to many practical values it is frequently used as a tool for teaching statistical concepts in many social science university programs. In our opinion, motivation to learn and to use SPSS during the studying process plays a significant role in building a positive attitude towards SPSS which influences its usage at the professional level after finishing study. Design/Methodology/Approach - The aim of this paper is the development of the model for analysing the acceptance of the SPSS among university students of social sciences. The model is based on the widely known Technology Acceptance Model (TAM). In addition to the traditional components of the TAM, six external variables were included. The model is tested using the web survey on the university students of social sciences from seven faculties at three Slovenian universities. Results - The evaluation of the questionnaire was performed. Descriptive statistics were calculated. The dependencies among the model components were studied and the significant dependencies were pointed out. Conclusion - The results of the empirical study prove that all external variables considered in the model are relevant, and directly influence both key components of the traditional TAM, ≫Perceived Usefulness≪ and ≫Perceived Ease of Use≪. Therefore, our model is useful to study the adoption and continuous utilization of SPSS among the students of social sciences. The obtained results are useful for educators, and can help them to improve the learning process.
