TY - GEN AB - The present study investigated how different graphical overviews affected learning with hypertexts, given differing levels of learners' prior knowledge, on N = 87 students. Overall, the learners seemed to profit more from global overviews (of the overall structure) than from local overviews (of several substructures). This was true in particular when the subject of investigation were learning outcomes at the macro-level of the text. With low prior knowledge, the learners showed better comprehension when they had access to a graphical summary of content. For learners with high prior knowledge, a more demanding graphical browser type was particularly useful when the text required deeper comprehension at the micro-level.
