Integration, enhancing the role of the TL?

Integrated units of work which focus on the same theme across all the key learning areas are of concern due to their limited focus. Surely students need opportunities to expand their horizons? There is so much to learn and discover one would think that using a different topic for each KLA would provide more scope for students to explore more topics; give them a smorgasbord so that they can taste lots of different things and will be more aware of possible choices as they go through life. Apparently this is not in line with current educational theory so it seems like a tremendous opportunity and challenge for the TL to provide lots of interesting resources so that when students do come to the library (either physically or virtually) they can explore new vistas. Selecting wisely is of paramount importance to ensure that young imaginations and hungry minds are provided with lots of stimulus and lots of options for wide reading. The Premier's Reading Challenge and similar programs can be helpful as they encourage students to read outside their normally favoured genre and topic areas. What do you think?
