The <strong>Open</strong> University of Sri Lanka<br />

limited to various types of boards and paper materials was shifted to multimedia<br />

materials and online activities.<br />

For example, teaching about the solar system using an OER video clip and experiencing<br />

colour changes in chemical reactions using acid-based indicators were very<br />

enjoyable lessons and easy for the students to understand. (Fig. 9.2.2)<br />

OER were very useful for students to visualize the concepts related to various situations<br />

such as things that cannot be reached practically and things that are not<br />

commonly available. Some such examples are; the three dimensional view of chromosome,<br />

various species in the deep sea, types of minerals available in various<br />

parts on the earth.<br />

Further, OER helped us to plan and implement very attractive lessons. Here the<br />

teachers, as well as students, were encouraged to look for new knowledge. This<br />

created an opportunity for us to share subject related resources such as activities,<br />

assessments, video clips etc.<br />

Our thinking enhanced in relation to the OER concept, as indicated by the second<br />

versions of our concept maps (Fig. 9.2.3)<br />
