WGU D298: Quality and Impact of Adult E-Learning Solutions

WGU D298, Quality and Impact of Adult E-Learning Solutions, is a graduate-level course in WGU's School of Education, typically taken by students in the Master of Education programs focused on education technology, instructional design, and learning experience design. The course asks you to step into the role of an instructional designer who builds online learning specifically for adults, then defends the quality and measurable impact of what you create. Rather than sitting a timed multiple-choice test, you demonstrate what you know by producing real design artifacts and reasoned analysis.

Direct answer: D298 is a performance assessment, so you pass by submitting written tasks that a WGU evaluator scores against a rubric. The winning strategy is to treat the rubric as your outline, ground every claim in adult learning theory and course-provided resources, and write clearly and completely so each rubric line is unmistakably satisfied.

Because the course centers on adult learners, it leans heavily on andragogy, the principles associated with Malcolm Knowles, and on the practical realities working adults face when they study online. That makes D298 both intellectually satisfying and demanding: you are not just memorizing theory, you are applying it to design decisions and then arguing why those decisions improve learning. This guide walks you through what the assessment covers, how hard students find it, a study plan tuned to this specific course, the mistakes that slow people down, a readiness checklist, and answers to the questions students ask most.

What the D298 performance assessment asks you to do

D298 is organized around a set of connected tasks that move from understanding adult learners, to designing a solution, to evaluating its impact. Based on the course's published task structure, expect to work through the following themes:

• Challenges adult learners face. Identifying real barriers to online learning for adults, such as juggling work, family, and school; time management; cognitive overload; limited technology skills; and sustaining motivation, then proposing concrete ways to address each one.
• Adult learning theory in practice. Applying andragogy and related principles, so your design choices reflect how adults actually learn best, including relevance, self-direction, and drawing on prior experience.
• Planning a standards-based e-learning solution. Designing a defined learning experience, for example a focused online module, that is aligned to clear learning standards or objectives and built with adult learners in mind.
• Quality of the design. Justifying instructional choices, accessibility, engagement strategies, and interactivity against recognized quality expectations for online learning.
• Measuring impact. Determining how you will evaluate whether the solution worked, including the use of data and learning analytics to assess effectiveness and inform improvement.

The through-line is quality plus impact: it is not enough to build something that looks polished, you must show it is grounded in theory and that you have a defensible plan to measure its results.

How hard is D298, and how long does it take?

Difficulty in a performance assessment is different from a knowledge exam. There is no trick content and nothing to cram; the challenge is doing the work thoroughly and writing to the rubric. Many students report that D298 is manageable and even enjoyable if they have any background in teaching, training, or instructional design, precisely because the tasks are applied rather than abstract. The friction most people mention is the volume of clear, well-supported writing required and the discipline to address every rubric prompt in full.

Timelines vary widely at WGU because the term is competency-based and self-paced. Many students report finishing D298 in a few focused weeks, sometimes faster if they already work in the field, while others spread it across a term alongside other courses. A realistic plan is to reserve dedicated writing blocks over two to four weeks rather than assuming a single weekend will be enough. Treat any timeframe you see online as a rough peer average, not a promise, and let the rubric and your own drafts set your pace.

A study and submission plan built for this course

Because D298 is task-based, your "studying" is really a build-review-revise cycle. Here is a plan that works well for design-focused performance courses:

• Read the rubric first, every time. Before drafting anything, copy each task's rubric aspects into a document and turn them into a checklist. Evaluators score against those exact statements, so your task is to make each one obviously met.
• Use active recall on the theory. Rather than rereading about andragogy, close the material and try to explain each adult learning principle in your own words, then relate it to a design decision. If you cannot connect the principle to a choice in your module, revisit it.
• Space your work. Draft a task, step away for a day, then return to review it against the rubric with fresh eyes. Spacing catches gaps far better than one long marathon session.
• Design a real, focused artifact. Keep your e-learning solution tightly scoped, for example a short module with clear objectives, rather than an ambitious course you cannot fully justify. Depth of justification beats breadth of scope.
• Practice self-testing your justifications. For each design element, ask yourself, "Which rubric point does this satisfy, and what evidence supports it?" This mirrors practice testing and exposes weak spots before submission.
• Use course resources and your instructor. Lean on the official course materials and reach out to your course instructor early with specific questions. Their feedback is the highest-value input you can get.

Because D298 sits alongside related education-technology coursework, it can help to see how assessment and design connect across the program. Guides such as D293 Assessment and Learning Analytics and D184 Standards-Based Assessment reinforce the measurement and standards themes you will use here, and D630 Designing Curriculum and Instruction I extends the design mindset.

Common mistakes students make in D298

• Describing instead of justifying. Rubrics reward reasoning. Saying what your module includes is not the same as explaining why that choice serves adult learners and meets the standard.
• Ignoring the adult in adult learning. Generic instructional design that could apply to children misses the point. Every task should visibly reflect the realities and preferences of adult learners.
• Skipping the measurement plan. Students often nail the design and then treat impact as an afterthought. Build a concrete, data-informed evaluation approach; it is a core outcome of the course.
• Partial rubric coverage. Missing a single sub-point can send a task back for revision. Map every rubric aspect to a labeled section of your response.
• Under-citing. Support claims with credible sources and follow the required citation format so your reasoning is verifiable and your work is clearly your own.
• Waiting too long to submit a first attempt. A complete, honest draft that comes back with evaluator notes is progress; perfectionism that delays submission is not.

D298 Readiness Checklist

Before you submit, work through these self-checks:

• Can you explain the core principles of adult learning theory in plain language and tie each to a design choice?
• Can you name specific challenges adult learners face online and propose a realistic solution for each?
• Can you state clear, measurable learning objectives or standards for your e-learning solution?
• Can you justify why your module's structure, interactivity, and accessibility choices fit adult learners?
• Can you describe how you will measure the solution's impact, including what data or analytics you would use?
• Can you point to the exact rubric aspect each section of your submission satisfies?
• Have you supported claims with credible sources and formatted citations correctly?
• Have you proofread for clarity, completeness, and originality before uploading?

D298 FAQ

Is D298 an objective assessment or a performance assessment?

D298 is a performance assessment. You demonstrate mastery by submitting written tasks, such as analyzing adult-learner challenges, planning a standards-based e-learning solution, and evaluating its impact, which are scored against a rubric rather than a timed exam.

How long does D298 usually take to complete?

It varies with your pace and background. Many students report finishing in a few focused weeks, especially if they already work in teaching or instructional design, while others spread it across the term. Plan dedicated writing time rather than expecting a single sitting to be enough.

What should I study most for D298?

Prioritize adult learning theory, including andragogy, and how to apply it to real design decisions, plus standards-based design and methods for measuring learning impact. The strongest submissions connect every design choice back to theory and to a rubric requirement.

How do I make sure I pass each task?

Turn the rubric into a checklist and address every aspect explicitly, labeling your sections so an evaluator can find each point. Justify your choices, cite credible sources, and revise based on any feedback you receive.

Do I need prior instructional design experience?

No. Prior experience can make the tasks feel faster, but the course provides the theory and resources you need. Students without a design background succeed by working carefully through the materials and applying the rubric methodically.
