The purposes of this study were 1) to study researcher characteristics, researchership, research competence and institutional support for research work as factors affecting research productivity, 2) to test for invariance of research productivity models across groups with size difference in Pedagogy Department, and 3) to compare the results of factors affecting research productivity using LISREL and Neural Network analyses. The sample consisted of 300 faculty members from 16 government universities. The research instruments were rating scales measuring research productivity, researchership, research competence and institutional support for research work. The reliabilities of the instrument ranged from .76-.96. Data were analyzed through using descriptive statistics, LISREL, and Neural Network analyses. The major findings were: 1) The average of each faculty member's research productivity was 0.40 pieces per year; 2) Researchership and research competence were high in average, and institutional support for research work was moderate; 3) Research productivity model fitted nicely to empirical data (Chi-square=85.692, p=0.072 df=68, GFI=0.961, AGFI=0.939, RMR=0.041). The test of model invariance across 2 groups of departments with different size indicated that the two models were invariant in form, and varied in loading and other parameters. The causal relationship using LISREL and Neural Network analyses suggested that researcher characteristic, research competence, institutional support for research work and researchership had direct effects on research productivity; 4) The comparison of analyses with LISREL and Neural Network indicated similar results. |
