On closer inspection, however, these two bodies of evidence actually complement each other. Some tasks, like those concerning basic knowledge or skills, are better suited to direct instruction. It may be better to provide explicit instruction on how to operate a 3-D printer, for example, than to have students figure out the directions on their own. We should tell student makers exactly how to perform straightforward tasks, so that they can devote cognitive resources to more complex operations. Meanwhile, tasks that themselves demand deeper conceptual understanding are likely to benefit from a productive-failure approach. In such cases, we should organize makers into groups and ask them to generate multiple solutions
