Effects of using a concept mapping strategy in database design on novice students' learning performance

International audienceThis paper presents the results obtained when concept map is used as a first step of data modeling. The sample of this study consists of 50 first-year university students. These students were assigned into two groups: an experimental group and a control group. Only the experimental group used the concept map as a first step of data modeling. We have studied entity-relationship diagrams made by students of the two groups during the achievement test to detect and analyze conceptual modeling errors. Student’s scores were also analyzed to see if there was a significant difference between the two groups. The results of the study revealed that there is a statistically significant difference between the mean scores of the experimental group and those of the control group in favor of experimental group
