| Sumario: | We investigated the effects of readymade versus self‐generated graphic organizers (GOs) on learning, comparing the performances of undergraduates (N = 81) tasked with learning a multimedia document. This document was either presented on its own (control group), with a readymade GO, or with a blank GO that students had to fill in either before or during the learning of the document. In line with previous research, adding a readymade GO increased students' memorization and transfer scores, compared with controls. By displaying the main ideas in the text and their hierarchical relations, GOs act as visual aids to learning. Results showed that self‐generating a GO was no more beneficial than viewing a readymade GO when students were placed in a dual‐task situation (generation + learning). However, when the students' information processing was guided by sequencing these tasks (generation then learning), they outperformed the control and readymade groups on memorization and comprehension. Lay Description: What is already known about this topic: Graphic organizers (GOs) consist in visual displays showing the main ideas of a text and their interrelations.Adding GOs to pedagogical document have been shown to improve students' learning.However, self‐generating GOs has been proven to be detrimental for learning in several studies. What this paper adds: In previous studies, self‐generation of graphic organizers (GOs) have often been carried out while learning, however this task should be separated from the learning task.In the present study, students' learning performances increased when the self‐generated task was separated from the learning task compared to a condition with a readymade GO.These benefits on learning were not observed when the self‐generated activity was not guided. Implications for practitioners: Graphic organizers gathering all the key elements of a multimedia document and highlighting the structure of this document should be used in order to increase students' learning.Students should not be placed in double‐task situation when learning from a pedagogical document.In‐task guidance should be provided when self‐generative tasks are performed.
