Abstract
The present research was conducted to find out the Laplace transforms perception and their relationships in order to teach and assist students to learn in meaningful ways. Students majoring in Science and Engineering at Najafabad Islamic Azad University in academic year 2010–2011 constituted the statistical population. A random sampling technique was then used to select 108 students to do the test. Based on Bloom’s taxonomy of learning, the goal-content table was prepared, and the questions were designed. Their validity was confirmed by three members of academic staff who had taught this course for several years. Reliability of test for internal consistency was also checked by Cronbach’s alpha (0.817). Then, the structural model of concepts was compiled. Data analysis showed that there was a meaningful and direct relationship between ‘knowledge of definitions and rules’ (p<0.05), ‘knowledge of reverse transform and concept of complementary theorem’ (p<0.05), and ‘knowledge of reverse transform and its applications’ (p<0.05). The results suggested that meaningful learning could be achieved by paying attention to the relation of these concepts and especially its applications because meaningful learning only takes place when learner can use learned concepts practically.
