Every resource, one click away: turning a map into a study hub
The technique that transforms a mind map from a teaching aid into a self-contained study hub. Every element can carry the PDF, video, slide deck or link that supports it — and students access them all without leaving the map.
Attach the actual resource (not a footnote saying where to find it) to every element. PDFs open in Marvex's built-in reader. YouTube and Vimeo videos play in a floating window over the map itself. Slide decks, Google Docs, MP3 lectures, web links — all accessible with a single click without ever leaving the map. The result: one shared URL replaces an entire VLE page, an email of links and a folder of PDFs.
Why footnotes don't work
Every teaching map I've ever seen, in its first draft, suffers from the same problem: notes that say things like *'see Smith 2019'* or *'cf. lecture 4 slides'*. Those are footnotes — they tell students where to find a resource without giving them the resource. The student then has to switch context, search a VLE, find the PDF, scroll to the page, lose their place in the map, and come back ten minutes later.
That ten-minute cost compounds. Across thirty resources in a topic-overview map, you've imposed five hours of friction on each student. Most won't pay it; they'll just skim the map and treat the footnotes as decoration.
The fix is mechanical: attach the resource, don't reference it. Marvex Studio's drag-and-drop file attachment makes this work the way it should — drop a PDF on a element, the file becomes the element's link target, students click once and read.
What attaches to what
PDFs — drag any PDF onto a element from your desktop. The PDF lives inside the map file (no external folder to manage). When a student clicks the link badge on the element, Marvex's built-in PDF reader opens with the document. Annotate, highlight, jump pages — all without losing the map underneath.
YouTube and Vimeo videos — paste a YouTube or Vimeo URL onto a element, and the link badge turns into a ▶ play icon. Clicking it opens an inline floating player that sits over the map. Students can re-watch a 90-second clip explaining a tricky step while the map is still visible behind it. This is the single feature most teachers ask for and most other mind-mapping tools don't have.
Slide decks (Google Slides, Keynote, PowerPoint) — for Google Slides, paste the share-link; for Keynote/PowerPoint, drop the file directly. The link opens in a new tab so students can present from it while keeping the map open in another window.
Audio recordings (MP3, M4A) — drop the audio file on a element and Marvex attaches it. Click to play in the OS default audio app, or — Pro tier — inside an inline mini-player.
Web links — paste any URL. Marvex auto-detects video URLs and routes them to the inline player; everything else opens in a new tab.
Email addresses — `mailto:` links work too. Useful for 'office hours' or 'subject coordinator' elements that should let students email the right person from the map.
The one-shared-URL pattern
Once every element carries its resource, the map IS the shared resource. Generate a public share URL from Studio → Share → Get shareable link. The URL renders a read-only version of the map at marvex.app/share/<your-slug> that students can open on phone, tablet or laptop without an account.
Update your map → the share-URL reflects the change. No re-uploading PDFs, no broken VLE links, no 'where can I find lecture 4 again?' emails. The map is the source of truth.
One URL replaces: the VLE page, the email of reading lists, the Google Drive folder of PDFs, the YouTube playlist, the 'helpful links' Padlet. Students bookmark one thing instead of seven.
The workflow in practice
Open the map you built in Lesson 2. Walk through it element by element and ask: 'If a student stopped here and wanted to go deeper, what would they need?' Drop the thing onto the element. PDFs onto factual-claim elements. Videos onto procedural ('how to' / 'how is X done') elements. Slides onto historical-context elements. Links onto further-reading elements.
A topic-overview map with 30-60 elements usually carries 15-25 resources by the time you're done. Some elements (definitions, structural anchors) don't need a resource. Some (a single concept that spans 3 papers + 2 videos) carry several — Marvex allows multiple attachments per element via the 'Add another' button in the link dialog.
Time investment: 20-40 minutes for a topic-overview map once you've gathered the source files. The payoff is that the map becomes the only artefact you need to send students — and the only artefact they need to revise from.
What changes for the student
Students who use a fully-resourced map report two consistent things in feedback. First, they actually engage with primary sources — the friction of opening a PDF drops from 'find it in the VLE' to 'one click', which crosses the threshold where most students will actually do it. Second, they revise from the map, not from the resources — the map becomes the index they navigate by, and the resources are background depth.
Both effects are measurable. In a 2024 informal study by a UK A-level chemistry teacher (Helen K., shared publicly on Substack), students using fully-resourced maps spent 2.3x more time engaging with primary literature versus a control group given the same resources as a flat reading list. Grade outcomes weren't measured but engagement was night and day.
Questions teachers ask
How big can the map file get with all those PDFs embedded?
+
Marvex stores PDFs in browser local storage when you drop them on a element — typical map with 20 PDFs is 15-40 MB. Browser local storage caps at ~50 MB per origin, so for very dense resource maps the desktop app (Marvex Studio for Mac/Win/Linux) handles up to 200 MB per map. Sharing the map via the share-URL streams the resources on demand, so map size doesn't slow down student access.
What about copyright on PDFs and videos?
+
YouTube/Vimeo embeds use the official iframe APIs, which honour the creator's embedding permissions — same rules as any other web embed. For PDFs you own or have licensed (institutional library access, your own slide decks, public-domain papers), there's no issue. For PDFs you don't have rights to redistribute, prefer linking out (paste the URL of the publisher's page on the element) rather than attaching the file.
Can students attach their own resources to the map too?
+
Not to your master map — share-URLs are read-only by design. But students can fork the map (Studio → File → Duplicate) into their own workspace, then attach their notes, recordings and questions to their personal copy. Many teachers explicitly ask students to do this as their first revision task.
