Common Mistakes in Instructional Design - How to Avoid Them for Better Learning Outcomes

Most instructional design failures aren't caused by a lack of subject-matter expertise or a poorly chosen platform. They're caused by a handful of recurring, easily named mistakes that show up across countless courses, from corporate onboarding to university electives. Recognising these patterns is often the fastest route to better courses — faster than learning an entirely new design framework from scratch.

Mistake: Writing Objectives Around Topics, Not Performance

"This module covers project scheduling" tells a learner what territory the module occupies but says nothing about what they'll be able to do afterward. Topic-based objectives are the root cause of a huge share of downstream design problems, because they give you no clear target for what content belongs, what counts as mastery, or how to assess it. The fix is mechanical but non-negotiable: rewrite every objective around an observable action — "create a project schedule with dependencies mapped correctly" — before drafting a single slide of content. If you can't picture a learner demonstrating the objective, it isn't specific enough yet.

Mistake: Front-Loading All the Theory Before Any Practice

A very common structure — and a very common failure — is a long stretch of explanation, definitions, and background theory before the learner gets to do anything at all. By the time practice arrives, much of the earlier explanation has already faded from working memory, and the learner has had no chance to test their understanding along the way. Interleave practice with explanation instead: introduce a small piece of theory, immediately apply it, then introduce the next piece. This keeps working memory load manageable and gives you constant, early signal about what's actually landing.

Mistake: Confusing Activity With Learning

Drag-and-drop exercises, decorative animations, and interactive hotspots feel like engagement, but busywork that doesn't require genuine thought produces the feeling of interactivity without its substance. The test for any interactive element should be simple: does answering or completing it require the learner to actually retrieve, apply, or evaluate something, or could it be completed correctly without understanding the content at all? If a matching exercise can be solved by process of elimination without knowing the material, it's decoration, not assessment — and it's taking up time that could go toward genuine retrieval practice.

Mistake: Writing Assessments That Test Recognition Instead of Recall or Application

• Multiple-choice questions where the correct answer is recognisable by its length or specificity, even to someone who hasn't studied the material.
• Questions that test whether a learner remembers a definition rather than whether they can apply the underlying concept to a new situation.
• Assessments pitched at a lower cognitive level than the objective itself claimed to target — an objective about "analysing" a scenario tested with a simple recall question.

Each of these produces assessment scores that look reassuring while masking a real gap in whether learners can actually use what they've learned. Writing genuinely difficult, well-calibrated distractors takes more effort than writing an obviously correct answer among three obviously wrong ones, but it's the difference between an assessment that measures something and one that doesn't.

Mistake: Skipping the Pilot Because the Deadline Is Tight

Piloting a course with even a handful of real learners before full launch is the single most commonly skipped step under deadline pressure — and it's also the step most likely to catch the errors that matter most: an instruction that reads two different ways, an example that only makes sense with hindsight, a navigation step nobody explained. These are exactly the errors that are invisible to the designer, who already knows what they meant, and glaringly obvious to a first-time learner encountering the material cold. A rushed pilot with five people, even over a single afternoon, routinely surfaces problems that would otherwise only be discovered after the course is live and learners are already frustrated.

Mistake: Spending All Available Time on Production, None on Structure

Teams facing a tight deadline often default to spending their limited hours on the most visible work — recording video, designing slides, polishing visuals — because it's the work stakeholders will actually see. The structural work — objective writing, sequencing, assessment design — gets compressed into whatever time is left, even though it determines whether the course actually works. One practical fix is to compress the mechanical drafting work instead of the structural work: a tool like Course Writer can generate a structured curriculum, lesson drafts, and assessments in under thirty minutes and export directly into Canvas, Blackboard, Moodle, and similar systems, freeing up the hours that would otherwise go into manual formatting so they can go into the sequencing and objective-writing decisions that actually matter.

None of these mistakes require rare expertise to avoid — they require deliberately checking for them before a course ships. Review your objectives for performance language, check whether theory and practice are interleaved, question whether your interactive elements demand real thought, calibrate your assessments against the objective's actual cognitive level, and never skip the pilot. Courses that avoid these five patterns consistently outperform courses that don't, regardless of production budget.
