There are different myths about this question, like the security of these techonologies enhances learning. On the other hand, research designs used count usually on some methodological unsuitables. One neglected aspect is effect of student satisfaction from classroom process in some dependent variables. In this paper both satisfaction level or degree of pleasantness are measured as for a student group from high school. Procedured used are blackboard, video and computer images animation.
Results shows that technology used has effects in pleasantness perceived in classroom.
The ability distributions of both groups were normally distributed. As expected, results show that sample size and DIF size improve power, although the power is rather low at each of the factor levels. The applications of the stereology in Neuroscience have been improved by the recent advances in the precision of stereological estimates. Here we make a comparision between two methods of estimating the coefficients of error.
