Exploration Module for Understanding the Functionality of the Internet in Secondary Education

In developing and successfully implementing a classroom project on ‘Internetworking’ in secondary education, the author found that there is a need for adequate educational software. Abstract informatics concepts have to be connected to real-life experiences. In this paper the concept of views that support different perspectives on the subject is applied to meet the requirements for educational software in secondary education in terms of activities and abstraction. The educational software developed allows analysis, simulation, and construction of network infrastructures and connects the visible behaviour, inner structure, and implementation details of Internet applications. Thus it provides a motivating approach based on the concept of discovery learning.
