The Use of Relational Blocks Demonstrated
Abstract: This demonstration will give conference participants an opportunity to see, work with and experience these newly designed manipulative tools, or relational blocks. A quasi-experimental study explored the effects of using these relational blocks to better teach pre-certification teachers basic relational database concepts. The three-week study was conducted with two classes and included a total of 37 students. One class used relational blocks while the other class used note cards. The remaining database concept material was the same for the two different classes. Class A, the control group, had an average pre-test score of 9.9 out of 50 and a post-test score of 27.7. Class B, the experimental group, had an average pre-test score of 16.4 and a post-test score of 34.3. Using ANCOVA, an F value of 28.7 was obtained which is significant at the .01 level.
