D858: Secondary Earth Science Curriculum

A study guide to WGU's D858, the graduate version for licensed teachers, focused on evaluating and aligning Earth science resources to standards and learner needs.

Updated October 2026 · 5 min read

D858 is the graduate counterpart to D857 in Western Governors University's Earth science route.

Its program (a Master of Arts in science education for already licensed teachers) is built around developing skills in curriculum development and evaluation, and WGU's course description stresses evaluating and aligning curriculum resources with secondary standards and student needs.

Where the undergraduate course centers on building a unit, this one centers on judgment: is this textbook chapter, simulation or lab activity accurate, aligned and accessible, and what would you change? Graduate candidates are expected to draw on classroom experience when they justify those decisions.

Key Concepts Explained

Criteria-Based Evaluation

Decide your criteria before you look at the resource: content accuracy, alignment to named standards, cognitive demand, accessibility, and time and cost. Then score the resource against each, with evidence.

Example: A video on plate tectonics is accurate and engaging (strong on accuracy), but has no captions and assumes fluent English (weak on accessibility). Recommendation: keep the video, add captions or a transcript, and pair it with a labeled map task.

Alignment, Not Coverage

Alignment means the resource asks students to do what the standard says. A resource that mentions a topic is not aligned if the task only asks for recall when the standard expects explanation or modeling.

Example: A standard expects students to develop a model of Earth-Sun-Moon interactions. A worksheet that asks them to label a diagram covers the topic but not the model-building expectation. Suggested adaptation: have students build and revise a physical model.

Designing for Variety

Adapting a resource means changing access without lowering the goal: alternative formats, vocabulary supports, tiered questions and choice in how to show learning.

Typical Assignments and How to Approach Them

WGU's guidebook does not list task prompts, so this table describes kinds of work the description points to. Follow your own instructions.

A Study Approach That Works

  1. Refresh the content. Be able to spot an inaccurate statement about Earth science quickly.
  2. Study the standards. Break each into the verbs it uses (model, explain, analyze).
  3. Build a reusable rubric. Six criteria you can apply to any resource.
  4. Practice adaptation. For one lesson, write three supports for different learner needs.

Frequently Asked Questions

How is D858 different from D857?

D857 is the undergraduate course focused on building a curriculum unit. D858 is the graduate course for licensed teachers, with extra emphasis on evaluating and aligning resources.

Do I need a teaching license for D858?

WGU's Master of Arts science education programs are described as for already licensed teachers. Check your program page.

What should I evaluate besides accuracy?

Alignment to standards, cognitive demand, accessibility and practicality, as the description stresses learner needs.

How do I use my classroom experience?

Give short, concrete examples of what you tried and what happened, linked to your decisions.

Will you write my evaluation for submission?

No. We provide tutoring, model examples and editing. You complete and submit your own work.

Where are the assessment details?

On your D858 course page and with your instructor. WGU sets the assessment.
