D864: Secondary Physics Curriculum

A study guide to WGU's D864, the undergraduate physics review course built around the content a secondary physics teacher needs, including Praxis preparation.

Updated October 2026 · 5 min read

D864 is the undergraduate version of WGU's Secondary Physics Curriculum course. WGU describes a comprehensive review for high school physics teachers preparing for the Praxis exam, covering forms of energy, thermodynamics, Coulomb's law, circuits, electromagnetism and waves, along with scientific discoveries, engineering and ethical issues in science.

The content is conceptual and algebra-based, which surprises strong physics students who expect calculus. The task is synthesis: pull together topics from earlier courses and show you can explain them clearly at the level a secondary teacher needs.

Key Concepts Explained

Conservation of Energy

Energy changes form but the total stays constant in a closed system. Many problems reduce to tracking where energy starts and where it ends.

Example: A 2 kg ball is released from a height of 5 m. Starting potential energy = m g h = 2 x 9.8 x 5 = 98 J. At the bottom, ignoring air resistance, all of it is kinetic energy, so 0.5 x 2 x v squared = 98 and v is about 9.9 m/s. No calculus needed.

Coulomb's Law in Words

The force between two charges grows with the size of the charges and falls with the square of the distance. Doubling the distance cuts the force to a quarter.

Ohm's Law

Voltage equals current times resistance. For a fixed voltage, more resistance means less current.

Example: A 12 V supply across a 24 ohm resistor gives I = 12 / 24 = 0.5 A. Power = V x I = 6 W. Include the unit with each step.

Typical Assignments and How to Approach Them

WGU's guidebook does not list task prompts. The table describes kinds of work a review and synthesis course points to. Follow your own instructions.

Work typeWhat it testsHow to approach it
Content explanationsConceptual commandExplain in plain language, then support with one equation
Algebra-based problemsApplying relationshipsStay with algebra; show each step
Teaching applicationPresenting to studentsChoose a grade level and a misconception to address
Science in society discussionContext and ethicsGive a specific example and a balanced view

A Study Approach That Works

  1. Audit your gaps. Rate yourself on energy, electricity, magnetism and waves.
  2. Review with concept maps. One page per topic.
  3. Practice explaining. Aim for a short explanation a student could follow.
  4. Stay at the course level. Practice algebra solutions, even where you know calculus.

Frequently Asked Questions

What is D864?

WGU's undergraduate Secondary Physics Curriculum course, a comprehensive review for high school physics teachers preparing for the Praxis exam.

Is D864 calculus-based?

No. WGU describes the content as conceptual and algebra-based.

How is D864 different from D865?

D864 is in the undergraduate route. D865 is the graduate version. Both share a WGU description.

Does D864 replace the Praxis?

No. The course supports preparation; check state requirements separately.

Will you sit the Praxis or the assessment for me?

No. We offer tutoring, custom answers and editing only. You complete and submit your own work.

Where are the assessment details?

On your D864 course page and with your instructor. WGU sets the assessment.
