Managing materials is one of the three key categories of study skills that contribute to students' ability to organize, remember and apply their knowledge. The other categories are managing time and managing information . To do well in school, students with learning disabilities must develop strategies that make them efficient, effective managers in each of these areas.. Unfortunately, many students do not develop these strategies intuitively. They need educators who are willing and able to provide them with explicit instruction, guided practice, and ongoing opportunities (and motivation) to hone the strategies they've learned.
