Choose the part of the job that fits the screen
A short decision exercise can work while a learner is away from a training room. They might review a condition, select an observation and explain their next step. A detailed equipment model with many small controls may need a tablet or desktop monitor so the learner can see the relevant parts together.
For example, a facilities team could practise recognising signs that a unit needs attention. The learner examines a virtual unit, selects an area to inspect and receives feedback based on the team's approved procedure. A closer view can show the detail needed for the next decision.
Make time for the exercise away from the live task. Your instructor decides what supervised practice and assessment should follow.
What changes when the learner uses touch?
On a phone, the learner's finger covers part of the screen while they tap. Small labels, crowded targets and controls that depend on a mouse hover can make an exercise hard to use. The interaction may need larger targets, fewer simultaneous choices and a way to inspect detail without losing the task instructions.
A tablet gives more room for a model, instructions and feedback together. It can suit a lesson where the learner compares several visible details. A phone suits a focused check or a short scenario that can be understood one view at a time.
Try the lesson in the orientation and setting your learners will really use. Check whether the text remains legible, whether a tap selects the intended item and whether the learner can recover after a wrong choice. If the exercise needs precise movement around a complex model, consider a larger screen.
Browser lesson or installed mobile app?
A mobile browser lesson opens through a link. An installed app needs a way to reach each device, whether through an app store or your organisation's device management. The choice depends on what the exercise needs to do and where learners will use it. Specify the supported phones or tablets for either version.
Decide whether learners use their own phones, shared tablets or managed devices. That affects sign-in, privacy and what happens when someone changes devices. If your course needs learners to pause, resume later or send records after a period without connection, describe those cases in the brief. Saving progress, syncing attempts and offline access must be designed and tested for the chosen delivery, rather than assumed.
Ask how the application will be updated when your procedure changes. For a browser lesson, the hosting arrangement matters. For an installed app, your team also needs an agreed way to install the new build on its devices.
Keep feedback useful on a small display
A mobile exercise can show the learner what happened after a choice and let them repeat it. Decide whether instructors need a record of each step, a simple completion result or no saved result at all. More recording is useful only when somebody will review it.
If several people share one tablet, ask how each attempt will be attributed. If learners use personal phones, decide what information the lesson should collect and where it will be stored. A dashboard or learning-system connection is additional scope, even if the lesson itself opens in a browser.
Test the feedback with learners before relying on scores. A missed tap and a misunderstood instruction can look like a knowledge error in a result. Watching people use the exercise helps the instructor tell those apart.
Bring these decisions to the first discussion
- What single task should the learner practise, and who will check the lesson against the current procedure?
- Will learners use phones, tablets or both, and are those devices personal or shared?
- Where will they use it, and what network access is available there?
- What should happen if someone stops halfway, changes device or repeats the exercise?
- Which results does an instructor actually need to review?
Use those answers to review a short working exercise on the devices your learners will use.
