D186 Learning as a Science carries catalog number EDUC 5066 and is worth 3 competency units. It asks you to apply learning sciences research to your teaching, to examine your own biases, and to build learning environments that are culturally inclusive. D186 and EDUC 5066 are the same course. It is the one course in the programme where the reading can genuinely change what you do on Monday, and the deliverables are scored on whether that connection is made explicit rather than assumed.
Mechanisms, not tips
Teachers accumulate strategies. What a learning sciences course adds is the mechanism underneath them, and mechanism is what the aspects are scored on. Knowing that spaced practice works is a tip. Knowing that memory strengthens when retrieval is effortful, and that spacing creates that effort by allowing partial forgetting, lets you decide when spacing will help and when it will just annoy a class that has not encoded anything yet.
The ideas that recur across versions of this course are worth naming because they carry most of the practical weight. Working memory is small and easily overloaded, which explains why a well-meaning explanation with three simultaneous representations fails. Retrieval practice strengthens memory more than review does, which is why quizzing outperforms rereading. Prior knowledge determines what new information can attach to, which is why the same lesson lands differently across a room. Feedback changes performance only when it is specific and there is time to use it. Transfer is hard and does not happen because you hoped it would.
The other half of the course is about the assumptions the teacher brings. Examining personal bias is not an ornament here; it interacts with everything above. Prior knowledge is judged by teachers, and judgments about which students have it are exactly where bias operates. A course that teaches the science without asking who gets the benefit of the doubt would be teaching half a subject, which is why the aspects tend to pair them.
One consequence of taking mechanism seriously is that the same technique becomes right or wrong depending on the moment. Retrieval practice on material a class has not yet encoded produces failure rather than strength, so it belongs after initial teaching rather than instead of it. Reducing working memory load is essential while a procedure is new and counterproductive once it should be automatic, because the load is what forces fluency. Worked examples help novices and slow experts down. Writing that treats a strategy as universally good has missed the point of the course, and an aspect asking you to justify a choice is asking exactly this question: why here, why now, why this class.
All work closes as Competent or Not Competent, with no letter grade and no ordinary grade point average. The 3 competency units describe the share of a six month flat rate term the course represents.
Turning aspects into an application plan
WGU keeps scoring detail inside your Course of Study rather than the public catalog, so read and count the aspects first. Each is judged separately and each has to reach a 2 for the task to pass. The aspect students most often underserve here is application, because summarising research feels like progress and applying it requires committing to something specific.
The budget, worked. Assume five scored aspects and directions pointing near 2,000 words. Reserve 140 words for an opening naming the setting and the learning problem and 120 for a close, leaving 1,740 of scored body. Flat that is 348 each. Weight it: 490 to the application aspect, 410 to the bias and inclusion aspect, and 280 to each of the remaining three. That comes to 1,740.
For every principle you discuss, write the classroom instantiation in the same paragraph. Splitting theory and practice into separate halves of a document is what produces the common return in which the application section repeats the theory section in shorter sentences.
A shape that forces application
Use your directions where they specify a structure. Where they do not, this table is worth building first as a planning tool and then narrating, because it makes an unapplied principle impossible to hide.
| Column | What you write in it | Why the column exists |
|---|---|---|
| Principle | The learning science finding, stated as a mechanism | Stops the entry becoming a strategy name |
| Evidence | The study or synthesis it comes from, with population and design | Separates established findings from folklore |
| Prediction | What the principle says should happen in your specific room | Turns a general claim into a testable one |
| Instantiation | The concrete change to a lesson, named by activity and minute | This is what the application aspect scores |
| Access check | Who might be disadvantaged by this change and what you do about it | Where the inclusion aspect lives in practice |
| Failure signal | What you would see if the change was not working | Prevents an unfalsifiable plan |
| Evidence of learning | What student work would show the principle had done its job | Connects the science back to outcomes |
The failure signal column is uncommon in student work and it lifts a submission noticeably. A teacher who can say what would convince them a technique was not helping this class is demonstrating exactly the scientific stance the course is named for.
The myths this course exists to remove
Some widely repeated claims about learning have not survived testing, and repeating them in a learning sciences deliverable is costly because the course is specifically about knowing the difference.
The best known is the idea that students learn better when taught in their preferred sensory modality. It is enormously popular and the experimental evidence does not support it. What is true, and worth writing instead, is that content has its own best representation: a map is a map, a rhythm is heard, a chemical process is often best animated. Matching representation to content is defensible; matching it to a label attached to a child is not.
A second is the claim that learners retain fixed percentages of what they read, hear or do. Those figures circulate widely and trace to no defensible study. A third is the family of claims about left and right brained learners, which does not describe how brains work. A fourth is the assumption that difficulty is bad. Some difficulty is what produces durable learning, and the practical skill is telling the productive kind from the kind that simply blocks access.
There is a general test worth carrying. A claim about learning that arrives with no population attached, no comparison group and a memorable number in it should be checked before it is repeated. Real findings come with boundaries: they worked with these learners, on this kind of material, against this alternative. Claims that apply to everyone, always, in every subject are the ones that turn out to have no study behind them at all.
Where you meet a popular claim in your own school, the strongest move in a deliverable is to name it, explain what the evidence actually supports, and offer the practice that survives. That reads as expertise. Repeating the claim, or ignoring it, does not.
What separates Competent from a return
Aspects score separately, so returns cluster on the application and inclusion aspects rather than on the reading. The three that recur are principles described but never instantiated, bias discussed in the abstract, and citations to popular sources for scientific claims.
- Every principle in the document is followed by a specific change to a specific lesson.
- Scientific claims are cited to research rather than to a training slide or a popular article.
- The bias section discusses your own decisions, with an example, rather than bias in general.
- Inclusion is handled as access to the same learning rather than as a lower expectation.
- No debunked claim appears as if it were established.
Performance assessment work at WGU can be revised and resubmitted with no grade penalty, so a return costs time rather than standing. In a six month flat rate term time is the resource that decides how many courses close, and the instantiation column is the cheapest protection available, because a document built from that table cannot leave a principle unapplied. Where this course sits alongside a proctored objective assessment, our position is unchanged: preparation only, never sitting or assisting during an assessment, and no handling of portal credentials.
Theory summarised and application missing?
Send the D186 rubric and the principles you are working with. You get the application table filled for your own subject and grade, with failure signals and access checks written in.
Five mistakes that stall D186
- Naming a strategy instead of a mechanism. The aspect wants to know why it works, because that is what lets you decide when it will not.
- Citing popular science for a research claim. A book aimed at a general audience is a starting point for reading, not evidence for an assertion.
- Writing the bias section about other people. Self-examination is the aspect, and a passage about bias in society generally does not meet it.
- Repeating the learning styles claim. It is the single most recognisable error in this course and it undermines everything around it.
- Applying every principle at once. A lesson redesigned around six findings is a lesson nobody could teach. Choose two and do them properly.
Three questions students send about D186
Is D186 the same course as EDUC 5066?
Is this a neuroscience course?
How do I write about my own bias without it sounding performative?

The assessments, one by one
The public catalog does not publish this course's PA/OA identity or task count. WGU Tutors publishes at most one PA manual per course and only from a WGU-controlled public rubric. Until that source exists, PA help begins from the student's real Course of Study and OA support remains preparation only.
