Motivation

• Database design entails considerable difficulty

• Traditional method vs. Project based learning

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.

Intelligent Database Systems Lab

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

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.

Intelligent Database Systems Lab

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

Experiment – Results and discussion

• The fourth hypothesis could be only partially supported

Intelligent Database Systems Lab

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.

Conclusions

further work:• Individual contribution & free-riders• Examine the effect of the PBL strategy in the long-

term

Comments• Advantages– This paper find a new ways for the database

course teaching, but the objectives mentioned in this article need more time to keep concerning.
