Motivation
• Database design entails considerable difficulty
• Traditional method vs. Project based learning
![Page 4: Intelligent Database Systems Lab Presenter : NENG-KAI, HONG Authors : CÉSAR DOMÍNGUEZ, ARTURO JAIME 2014, CE Database design learning: A project-based](https://reader035.vdocuments.us/reader035/viewer/2022070409/56649e985503460f94b9b070/html5/thumbnails/4.jpg)
Intelligent Database Systems Lab
Objectives• Integrate both perspectives of a project as an effective
database learning method.
• Organize, manage and control the development of
project tasks and their deliverables by adopting a CMS
tool.
• Examine the results of two academic years using this
method.

Intelligent Database Systems Lab
Methodology-project-based learning(PBL)• A learning method based on developing projects .
• Students plan, implement, and evaluate projects that
have real world application beyond the classroom.

Methodology-project-based approach• Project will be done by a student team following the
ideas of PBL.
• Using a Work Breakdown Structure (WBS) and Gantt
chart to divide a project into tasks.

Intelligent Database Systems Lab
Methodology-project-based approach• Students choose the database project topic according
to their own interest.
• Role playing: developer & client
• Evaluation

Intelligent Database Systems Lab
Methodology-database software and CMS• Students need the use of two computer programs for
their development: a database management system,
and an XML editor
• Approximately 100,000 lines per table were randomly
generated
![Page 9: Intelligent Database Systems Lab Presenter : NENG-KAI, HONG Authors : CÉSAR DOMÍNGUEZ, ARTURO JAIME 2014, CE Database design learning: A project-based](https://reader035.vdocuments.us/reader035/viewer/2022070409/56649e985503460f94b9b070/html5/thumbnails/9.jpg)
Intelligent Database Systems Lab
Methodology-database software and CMS• CMS:
1. Learning method description
2. Team management
3. Task management
4. Communication

Experiment - Research hypotheses1. Students that follow the project-based method will
obtain better results than their counterparts with a
traditional method
2. The students that obtain excellent results preferred to
follow the project-based method than the traditional
one.

Experiment - Research hypotheses
3. The project-based method will influence the whole
student group
4. The project-based method will influence the students
that only follow a traditional method

Conclusions• Students that follow this method obtain better results
than students that follow a traditional learning strategy.
• The introduction of such a method in a student subgroup positively influences the whole group.
