Learner - content interaction is a defining characteristic of education that results in changes in the learner's understanding, the learner's perspective, or the cognitive structures of the learner's mind.Good pedagogical practice will include instructional strategies that support learner interaction with the content, therefore it is central to make the content accessible to our students and to maintain their interest by engaging them sufficiently.

The oldest form of distance teaching that aimed to facilitate interaction with content was the didactic text. The selection and use of appropriate media and technologies stand as an essential factor for establishing and maintaining effective interaction with educational material. New technologies can make learner-learner interaction much easier and more valuable.

The importance of this type of interaction is stated by Moore & Kearsley (1996): "it is not too difficult to present information over a distance, but getting people to participate and making learning active at a distance is much harder". In eTwinning projects is very important to make interaction with the content as effective as face-to-face instruction since the content is a silent but active participant that is always present in interactive learning processes.

Strategies for Incorporating Interaction

• Present content in more than one format.
• Have students participate in online simulations.
• Provide links to online resources which allow students to explore the topic in more depth.
• Use audio and video clips for access to guest lecturers and field experts.
• Use live, synchronous web conferencing (Interwise) for class events, such as guest speakers and student presentations.
• Minimize the amount of instructor-generated content and guide students into generating their own content.
• Require participation in discussion forums that require students to reflect and build on the content.
• Assign activities that require students to interact with the content and explore the topic in greater detail.
• Use self-tests to allow students to check their understanding of content.Keep the format of your lessons consistent.
