The Educational Problem
The educational problems were:
- To increase the interest and motivation of students:
- To meet the requirements of modern professional education for:
- Improvement of students’ practical skills;
- Group work on common projects;
- Responsibilities allocation for the execution of the common tasks;
- Creating skills in students to define their own timetable in order to meet specified deadline.
The problem was how to reorganize the Computer Aided Design course in order to:
- achieve practice oriented education during the school year,
- to obtain knowledge in the fields of schematics and printed circuit design, analog and digital circuit simulation,
- obtain better students’ learning outcomes
In order to achieve these objectives and resolve problems a new trialogical educational approach was introduced with
- Using cloud computing technologies,
- Up-to-date communication tools for student-teacher connection
- Continuous monitoring and assistance students’ activities
Trialogical approach was used to address
- Team work on shared object (report)
- Continuous and prolonged work (within 2 weeks) before the laboratory work.
- Strengthening the tasks of circuit design using devices’ data sheets and simulation of the circuits, calculations of circuit’s currents and parameters
- Continuous monitoring and teacher assistance in this process, providing help on request
- Reporting on the individual contribution of each team member to the overall project
- Respect to meet the deadline (after the prescribed date the project is locked for editing)
The pilots were conducted with two classes of 52 students – 11 grade classes (15 weeks). In addition to the project work, students were required to submit seven individual homework assignments. Each team had to choose a project subject from a list provided by the teacher.
All participants had to register individual Google accounts. The teacher was responsible for creating a Google Docs document for each project report and sharing it with the team.
The key successes were:
- Developing collaboration skills in students;
- making use of project based learning;
- using problem solving as a teaching tool;
- using modern cloud technologies as shared environment for collaboration during this course with timely, appropriate and detailed feedback and reflection;
- It is collaborative in nature and uses enabling and empowering technologies;
- It fosters Contextual learning bridging the disciplines and curriculum areas.
