Evaluating Mediums for Presenting Information

How We Got Here: A Brief History of Information Mediums

People have always wanted to share knowledge, stories, and news. But the way we share information has changed dramatically over the centuries. Each new medium (a medium is simply the format or channel used to deliver information) brought exciting advantages — and also created new challenges. Understanding that history helps you see why evaluating mediums matters today.

Here's the key question this lesson answers: When you encounter the same topic presented in different formats, how do you decide which medium does the best job — and why?

Core Principles: What Makes a Medium Effective?

Before you can judge whether a medium works well, you need a set of criteria — think of them as a checklist. Below are four key principles you can use every time you compare mediums.

Visual Guide: Comparing Mediums at a Glance

The diagram below maps four common mediums across two important dimensions: depth of information (how detailed the content can be) and sensory engagement (how many senses — sight, sound, touch — are involved). Notice where each medium lands and think about what that tells you.

As you can see, print text offers excellent depth (you can pack a lot of information into a book) but is low on sensory engagement — it's just words on a page. Video is highly engaging with sound and moving images, but it may sacrifice some depth because you can only cover so much in a few minutes. Multimedia aims for both high depth and high engagement by combining text, images, video, and interactivity — though it can sometimes overwhelm the reader.

How It Works: A Framework for Evaluation

When you're asked to evaluate mediums, you're really being asked to think critically about how the format shapes the message. Here is a step-by-step process you can follow.

The MAPS Framework

Remember the word MAPS — it stands for Medium, Audience, Purpose, and Subject. Every time you evaluate a medium, run through these four questions:

• M — Medium: What format is being used? (print book, website, documentary, podcast, infographic, etc.)
• A — Audience: Who is the intended audience? A young child needs a different medium than a scientist.
• P — Purpose: What is the goal? To inform? To persuade? To entertain? To teach a skill?
• S — Subject: What is the topic? Some subjects (like surgery techniques) are better shown on video. Others (like legal arguments) need the precision of written text.

The flowchart below shows how the MAPS framework guides your evaluation from start to finish.

Notice how you don't just pick the "coolest" medium and call it the winner. You think about whether the medium actually fits the audience, the purpose, and the subject. That's what makes your analysis thoughtful and convincing.

Medium-by-Medium Breakdown

Now let's dig into each medium and lay out its specific advantages and disadvantages. The table below gives you a quick side-by-side comparison, and the text that follows adds more detail.

Here's an important detail: digital text is different from print text in a few key ways. Digital articles can include hyperlinks that let you jump to related sources instantly. They can be updated at any time, so the information stays current. But they also come with distractions — ads, notifications, and the temptation to click away to something else.

Video is especially powerful when you need to see something in action. Imagine trying to learn how a tornado forms just from words versus watching real footage with narration. The video wins for that purpose. But if you need to study specific statistics about tornado damage over the last 50 years, a detailed article or report would be much more useful.

Multimedia tries to give you the best of all worlds. An interactive website about climate change, for example, might combine written explanations, data graphs you can click through, embedded videos, and even a quiz. The challenge is that all those features can be distracting if they aren't well-organized.

Worked Example: Evaluating Two Presentations of the Same Topic

Let's walk through a complete evaluation together. Imagine your teacher gives you two sources about the water cycle, and asks you to evaluate the advantages and disadvantages of each medium.

Strengths, Limitations, and Common Mistakes

Evaluating mediums sounds simple, but students often fall into a few traps. Let's talk about what works and what to watch out for.

Beyond the Basics: Media Literacy in the Real World

The skill you're building here — evaluating mediums — is part of a bigger concept called media literacy. Media literacy is the ability to access, analyze, evaluate, and create messages in many different forms. It's one of the most important skills for the 21st century.

In high school and beyond, you'll encounter assignments that ask you to not only evaluate mediums but also create content in different mediums and defend your choices. The analytical thinking you're practicing now is the foundation for all of that work. Every time you pause and ask yourself, "Is this the best way to present this information?" — you're thinking like a media-literate citizen.
