1) A comparative study examined the instructional effectiveness of video-based versus print-based instructional materials for teaching practical skills. It found that students using video-based materials exhibited superior skills acquisition and craftsmanship, though both were equally effective for teaching theory. 2) A non-comparative study evaluated the use of interactive whiteboards in classrooms. Teachers reported improvements in student motivation with the whiteboards, and most teachers found them effective for student learning gains. However, setting up the whiteboards was problematic when teachers had to do it alone.
