D858 Secondary Earth Science Curriculum, catalog number EDUC 5330, is the two-CU graduate version of the Earth science curriculum course, covering Earth's processes and materials, Earth, Sun and Moon relationships and the wider universe. It is designed for candidates entering teaching with a subject background already, and the compression to two competency units reflects that assumption. The work is not learning Earth science. It is converting expertise you already hold into decisions about what a fifteen year old should meet, in what order, and how you would know they learned it.
The expert's problem is not knowing less
Candidates arriving with a science degree tend to hit the same obstacle, and it is not gaps in content. It is the curse of knowing: once a concept is fluent, the steps that made it learnable have disappeared from view. Plate tectonics feels obvious to someone who spent years with it, which makes it easy to design a unit that starts three ideas past where a secondary student can enter. Curriculum design at graduate level is largely the work of reconstructing those missing steps.
The second difference from an undergraduate route is the standards. Subject expertise says what is true and interesting; a state framework says what a course is accountable for, and the two overlap imperfectly. Areas you find compelling may occupy a single performance expectation, while areas you consider routine may carry three. Reading the framework as a specification rather than as a summary is the fastest way to make a graduate curriculum document defensible.
The third is pace. Two competency units is a short course by design, which makes scope control the main risk. A candidate who begins by writing detailed lessons will run out of term before the curriculum-level aspects are answered. The document is about a course, not about a week, and keeping the altitude constant is what allows the work to finish inside the time the credit implies.
Planning a two-CU graduate course
The scoring detail sits in your Course of Study rather than in the public catalog. Read it first, because in a compressed course the aspect list is also your scope limit: anything you write that no aspect asks about is time you will want back later. Each aspect is judged alone against a three-point scale and each needs a 2, so breadth across the aspects beats depth in one.
The word budget, worked. Suppose five scored aspects and directions asking for roughly 1,500 words. Reserve 110 to state the course context and 90 for a close, leaving about 1,300, or 260 an aspect. Then shift 55 words from each of the two most descriptive aspects into the rationale aspect, because graduate curriculum work is judged on justification and a well informed candidate can produce description almost automatically.
The time budget, worked. Two competency units at graduate level usually runs to thirty or thirty-five hours for a candidate with subject background. Give eight to ten to the standards framework itself, which is the part most subject specialists have never read closely, twelve to fifteen to building and defending the sequence, and the rest to writing. The framework hours are the ones that shorten everything else.
A structure that fits a graduate curriculum document
Use the arrangement your directions prescribe where they give one. Otherwise this order keeps a compressed document complete.
| Section | What belongs in it | What earns the aspect |
|---|---|---|
| Context and constraints | Grade, course length, student prior science and the framework in force | Makes every later decision judgeable |
| Standards analysis | Performance expectations grouped, with what each actually demands of students | Scored for reading the standard rather than restating it |
| Sequence and rationale | Units in order with the dependency and accessibility reasoning behind it | The aspect that separates graduate curriculum work from content knowledge |
| Entry points | Where each big idea can be entered by a student who does not yet hold it | Scored for addressing the expert's blind spot directly |
| Practices and phenomena | Observable events anchoring units and the practices students use | Scored where three-dimensional design is named |
| Assessment strategy | What evidence is collected, when, and against which expectation | Scored for alignment and distribution |
| Sources | Framework documents, science teaching literature and content sources, APA | Scored where citation is named |
Keep the level of detail consistent. A document that describes six units in a paragraph each and then supplies a full lesson for unit three has answered the sequencing aspect twice and the detail aspect not at all. If one unit genuinely needs more space, say why in a sentence so the imbalance reads as a decision rather than as enthusiasm that escaped.
Evidence craft for a candidate who already knows the science
Subject expertise creates a specific citation risk: writing from knowledge without sourcing it, which reads as unsupported in a graduate document.
- Cite the framework by code for every coverage claim, even when the content is obvious to you.
- Support pedagogical decisions with science education literature rather than with your own experience of learning the subject.
- Cite research on student misconceptions in Earth science, because a graduate document is expected to plan for them rather than discover them.
- Where you simplify a concept for secondary students, say what the simplification costs and where it will need revisiting.
- Attribute adapted materials, including anything from a department you have worked with or observed.
- Apply APA where directions require it, including for standards documents and curriculum guides.
- Where your own degree work informs a claim about how the discipline reasons, cite the disciplinary source rather than your experience of it, because a graduate document is assessed on what it can point to.
The most useful sentence a subject specialist can write in this document is the one naming what a student must already believe before a unit makes sense. It is the sentence that proves the curriculum was designed for learners rather than derived from a syllabus.
What separates Competent from work sent back
Because aspects score independently, a graduate return usually names either altitude drift or a rationale that assumed rather than argued.
- The document stays at course level throughout.
- Standards are analysed for what they demand, not summarised.
- Sequence rests on dependency and accessibility, both stated.
- Entry points are identified for the ideas students find hardest.
- Phenomena and practices appear as designed elements.
- Citations support pedagogical claims as well as content ones.
Performance assessment work at WGU can be revised and resubmitted without a grade penalty, and in a two-CU course the return cycle is the main risk to your term rather than the writing itself. Terms run six months at a flat rate, so a compressed course that closes in three weeks rather than nine is what makes room for the heavier ones. We prepare only for any proctored objective assessment, never sit it, never ask for portal credentials, and never teach lessons, contact schools or complete field placement paperwork.
Five mistakes that cost time in D858
- Writing lessons instead of curriculum. The aspects operate at course level, and detailed lesson work answers none of them.
- Assuming the standards match your degree. A framework allocates emphasis differently from a university syllabus, and the mismatch is where coverage gaps appear.
- Starting units above the entry point. Expertise hides the steps, and a unit that begins three ideas in leaves most of a class behind.
- Citing nothing because you know it. Graduate documents are judged on support, not on confidence.
- Underestimating a two-CU course. Compression means less writing, not less thinking, and the scope discipline it demands is what most candidates find hardest.
How support works on this course
Send the task directions and the scoring detail from your Course of Study. What comes back is a standards analysis that reads the framework as a specification, a sequence justified on dependency and accessibility, entry points for the concepts secondary students struggle with, and a document held at a consistent altitude so no aspect is answered twice while another is empty.
For candidates coming from a geology, physics or environmental background, most of the work is translation rather than learning, and that translation is exactly what we do fastest.
Scope control is the other thing we hold you to. In a two-CU course the largest risk is a candidate who writes beautifully about the area they know best until the document is unbalanced and two aspects remain unanswered with a week left in the term. Setting a word ceiling per aspect before drafting, and treating it as a hard limit rather than a target, is what keeps a compressed graduate course inside the time its credit implies.
Questions students ask about D858
Is D858 the same course as EDUC 5330?
Why does D858 carry fewer competency units than D857?
I have a science degree. Do I still need help with this course?
Subject expertise that will not convert into curriculum?
Send your directions and framework. You get a standards analysis, a sequence argued on dependency and accessibility, and entry points for the ideas students find hardest.

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.
