How long should my online course be? Your cut-out-and-keep guide to time resonance

In my last post I promised to write more about designing online courses. How long should your online course be? I’m thinking of a course that the learner takes over a period of time, not one that is instantly downloaded.

My first reaction to the question is a simple knee-jerk: well, obviously, it’s as long as it needs to be given the audience, the subject matter and the course goals. But you know, I think it’s a bit more complicated than that.  Some patterns work better than other. There are lots of unspoken expectations about time in courses. Here’s my take on the meaning of time promises, based on personal resonance and a bit of Googling. Somewhere in this list there is an infographic begging to be let out.

As you go through, consider your own material and the nature of your audience. What are the expectations? What would work well and what would be downright odd?

The Miracle Zone

One hour
Task acquisition. Software mastery. Bite-sized videos.

24 hours
I once bought a book called Learn CSS in 24 hours. Turns out that the 24 hours aren’t “a day”. They are 24 …hours. It is a good book. I have it about 2 years and I think I’m only on Hour 11, although I’ve already had to jump ahead to Hour 22.

You can learn a lot in a day, but I am not convinced you can do it very easily online.

48 hours
Popular film with Nick Nolte and Eddie Murphy. Lost weekends in Vegas.

Mysteriously lacking in resonance, although ‘weekend retreat’ has a much better resonance. Very difficult to deliver online though: people can’t sustain their attention, and are constantly tugged away to dinner, films and football.

3 days
Packed with resonance. Death and rebirth. Meditation. Deeper personal change. Good for live events, more difficult for online.

7 days
Seven days of creation: goodness, a lot is possible in 7 days.

There’s a whizz-bang feel to seven days. Throw yourself in and get results. At the same time, it’s a very demanding time promise. What if you’re working? Do you take a week’s holiday? Do you do it in the evening? Also it is hard to stay engaged over 7 continuous days – real life gets in the way. It might be possible if your target is young and single.

The danger of seven days is that the audience fades away after 4, because they can’t sustain their involvement. Also, if instruction is continuous, there is limited time for response and reflection. The space for response is absolutely critical to the success of an online course.

(Digression: I bought a book on organising called Unclutter Your Life in One Week.  It’s a good book but sadly it’s not true. Again, the author points out that the 7 days are conceptual, rather than continuous: in this case, I don’t think the concept really quite worked. I felt slightly cheated, although I do wonder if I would have bought a book called Declutter Your Life in Approximately 8 months, Give or Take).

10 days/2 weeks
Weight loss zone, for some reason. Probably because this is the minimum time you can work out and get some visible results. It’s also the War Zone. 10 days that shook the world.

The Realistic Change Zone

21 days, 28 days
Habit change zone, especially for diet and fitness. If you can do something for 21 days, perhaps you can change forever? 21 days is short enough for momentum to power you through, long enough for some significant change to happen. (However! My trusty Google tells me that the psychology researchers from UCL say it’s more like 66 days to change a habit). Damn you, evidence-based people.

21 days feels good. It’s an achievable stretch. Actually, it feels stretchy. 21 days of yoga. That would work.

31 days
Daily practice over one month. 31 days to a better blog (but not in February).

Suggests a slow build and the acquisition of a more deeply engaged habit. As with 7 days, there’s an risk of overkill here: people do need a bit of space.

5 weeks
Untidy. We really don’t like fives as weeks.  Unless they are paired with another 5 or doubled to 10, when they recover the magic of 5. Five weeks to 5k. Five weeks to lose 10 pounds. This is a rather good length for a course but you might feel driven to add a week to make it neat.

The Goldilocks Zone

6 weeks
Many things are possible: transformation, skills acquisition, weight loss. This is the Zone of Credibility. A sweet spot. Change seems possible, even likely.

I like 6 weeks. It is the typical length of a half-term in our local school system. It’s the typical length of many of my projects – it can cover planning, executing, and reporting rather nicely. There is room to grow, room to think.  Room for homework assignments. Room to discuss things, reflect, work, conclude.

7 weeks
Strangely unpopular, unlike 7 days. If you feel compelled to go with an awkward length, remember the power of alliteration. Seven pounds in 7 weeks.

8 weeks
The alternative to 6 weeks, if you have more ground to cover. Mysteriously more powerful than 2 months, but very bad for alliteration.

10 weeks
The Academic zone, where I am in the UK. Evening classes, terms, major change. Within an online course, unless certification is at stake (you have to deliver two essays and get 60% in an exam), learner momentum starts to fade. We move from powering through to slogging it out. It feels like a big commitment, especially if there are no breaks.

The interesting thing is that people will do longer courses – but they might need these broken down into units and they might need rest weeks/implementation weeks. Think of pulses of work and rest.  Absorb, learn, reflect, rest. There’s often an natural energy in the work you want to communicate and it will help greatly if you can build it in.

The Long Term

3 months. 90 days. 12 weeks
We’re back in the Fitness and Weight loss zone.

4 months, 5 months:

16 weeks to a better body? Tricky. But this is the beginning of the Marathon zone, for a reason.

6 months
The business planning zone/business turnaround zone. Rather long for personal change, unless it’s with a highly committed inner circle.

The Distant Certificate Zone

9 months
Pregnancy and birth, obviously.  The true length of the academic year.  Time to acquire a diploma or formal certification.

12 months
A full year. The full working cycle for most of us. Probably too great a stretch for an online course, but you might plan for a yearly cycle in months or seasons.

One year/two years/three years/five years

The zone of academic transformations, via degrees, or business planning for golden futures (but note: you might be planning your next five years, but you are probably not going to spend that amount of time on it).

Merely thinking about these longer  time frames may bring you out in hives: wow, I have no idea if I can deal with my customers for the next eight weeks, let alone three years.

How do you decide what’s right for your material?

I think it comes down to identifying the natural cycle in your work. How long is long enough to absorb the lesson, reflect and experiment? My hobby is working with glass. The evening class I’m doing now takes us from initial idea to completed stained glass panel in 10 weeks, with a one week break.  It’s all broken down into phases: sketching and choosing colours. Cutting the pattern. Painting. Leading. Every week is full, but it’s not rushed, it’s been broken down, and at the end there is a completed piece. That’s the kind of effect you often want: an achievable goal, delivered at a pace that suits you, your people and your material.

I would love to know about other time resonances, especially what seems wonderful or just plain wrong. Seven weeks feels very odd, to me.  :)

Clever and informative. I’m currently outlining my first course, a free 30-day self-love bootcamp of sorts. I think that when I run a paid course it’ll be a six-week course. I just like the feel of six weeks for some reason.

Glad you found it useful Jen! It’s interesting to look at the ready-made resonances. 6 weeks is popular for a reason, although it all depends on whay you’re trying to achieve.

Fall for a Blogger in One Post. <– That should be the title of this one.
Great stuff. I needed this information and the laughs that came along with it. I'm off to read everything else you've written on the subject. Thanks.
