TL;DR
A tradeoff between organizers that are useful initially and those that promote structural learning are suggested, which suggests a tradeoff that is faster than the implicit group in the test phase.
Abstract
Two experiments examined the effects of graphical organizers on users' navigation of a 150-page hierarchical website of aquatic animals. In Experiment 1, users were given either a non-clickable map (map group) or no map (no-map group) and answered 30 questions by searching the website. The map group was more efficient (visited fewer pages) on the first 20 questions (learning phase) but the no-map group was marginally more efficient on the last 10 questions (test phase), and displayed more flexible search strategies. In Experiment 2, users were either given a simplified organizer locating the current page in the website (explicit group) or an alphabetized list of superordinate pages (implicit group). The task from Experiment 1 was repeated. No differences in efficiency were found, but the explicit group was faster than the implicit group in the test phase. The results depended on individual differences in spatial skills. These results suggest a tradeoff between organizers that are useful initially and those that promote structural learning.

Cognitive ScienceCognitive Load During Problem Solving: Effects on Learning

It is suggested that a major reason for the ineffectiveness of problem solving as a learning device, is that the cognitive processes required by the two activities overlap insufficiently, and that conventional problem solving in the form of means-ends analysis requires a relatively large amount of cognitive processing capacity which is consequently unavailable for schema acquisition.

The meta-analysis showed that the overall performance of hypertext users tended to be more effective than that of nonhypertext users, but the differences in efficiency measures were consistently in favor of nonHypertext users.

The results showed that participants in the mixed condition performed better than those in the other 2 conditions and that the performance of knowledgeable participants was superior to that of nonknowledgeable participants.

The results show that non-knowledgeable users tend to rely more heavily on navigational aids than knowledgeable users, and that aids were used primarily during browsing.

A study on information retrieval using a commercial hypertext-based help system found that the predominant search strategy was "browsing" (characterized by scanning tables of contents and paging through topics), rather than employing the indexes ("analytical search").

Both overviews produced better memory for text topics and better breadth of recall compared with traditional text, but when readers lacked specific study goals, the unstructured overview produced a more fragmented knowledge structure, suggesting that minimally structured overviews may be better for specific learning tasks than for gaining familiarity with new topics.

It was revealed that the presence of system links affects internal representations: Participants who were exposed to the hypertext systems produced concept maps that largely reflected their system links, and hypertext was revealed to have only limited educational benefit for users in this study.
