D679 Elementary Science and Engineering Methods, catalog number EDUC 5084, is the two-CU graduate science methods course in the WGU Master of Arts in Teaching sequence. It covers integrating science and engineering practices into the elementary classroom, the same material as the undergraduate D672 (EDUC 2254). The graduate emphasis lands on discourse. Investigations produce observations; only structured talk turns observations into explanations, and planning that talk is where the graduate craft sits.
Why EDUC 5084 puts argument at the centre
The practices in modern science standards culminate in one that elementary teachers find hardest: engaging in argument from evidence. Children make a claim, support it with data they gathered, explain why the data supports it, and consider a competing explanation. That is a demanding piece of reasoning and it does not appear spontaneously after an activity. It has to be taught as a form, practised in a structure, and supported with language.
The classroom version at elementary level is achievable. Children write or say a claim, point to what they observed, and complete a sentence beginning with because. A partner offers a different claim, and the group decides which the evidence supports better. Ten minutes, and it is the ten minutes that converts an activity into science. A graduate methods submission that plans this in detail, with the actual stems and the actual grouping, is answering the highest-value aspect in the course.
Discourse moves are the teacher's half of that and they are nameable. Asking a child to say more. Asking a second child to restate the first child's idea. Asking whether anyone saw something different. Waiting. Asking what would change your mind. Each is a specific move with research behind it, and a plan that names three of them and says when they occur reads as expert rather than aspirational.
Engineering in the graduate version carries the same demand in a different form. A design decision has to be justified against criteria and constraints, and children should be able to say why one design outperformed another rather than which one they liked. Testing produces data, and data is the basis of the argument, which is the point at which engineering and science rejoin.
Assessment of practices is the last graduate expectation and the least practised. A performance that combines an idea, a practice and a crosscutting concept cannot be assessed with a recall item. It needs a task where children apply the idea to a new situation and a scoring approach that describes what the reasoning looks like at different levels. Building one of those is difficult, which is exactly why it is scored.
Materials management is the unglamorous part that determines whether any of this happens, and graduate plans are expected to have solved it rather than to have hoped. Thirty children, sets of equipment and a forty-minute period produce a distribution problem and a collection problem, and both eat instructional time when they are improvised. Trays prepared per group, a stated collection signal, a fixed place for used and unused materials, and a child in each group responsible for the set are ordinary answers that cost nothing and buy back several minutes. Evaluators reading a plan for feasibility look for exactly this, because a lesson that cannot be run in the time available has not been planned.
Reading the rubric into a graduate methods plan
The scored aspects live in your Course of Study rather than the public catalog. Count them before drafting. Each is scored alone on a three-point scale and needs a 2, and in a two-CU course there is no room to recover a thin aspect with length elsewhere.
If D679 is assessed by performance assessment, mirror the rubric's aspects in your headings. Where an aspect names a practice, quote the practice from the standards document and then show where in your lesson children perform it, since naming a practice is not the same as building one into a task.
A worked word budget. Assume six scored aspects and directions pointing at roughly 1,700 words. Reserve 110 words for context naming the grade, the phenomenon or problem and the materials, and 80 for a close. That leaves 1,510 across six aspects, or about 251 words each.
Weight toward discourse and assessment. The aspect covering argumentation or discussion deserves 350, and the aspect on assessing the practice deserves 330. Aspects on materials, safety or grouping can hold at 180. The two-CU discipline applies: cut every sentence explaining what inquiry means and spend the space on what children will say and how you will know they learned.
A shape that fits a graduate science methods lesson
Directions with their own template win. Where the shape is open, this order keeps the reasoning and the talk visible rather than assumed.
| Phase | What it must specify | The thin version |
|---|---|---|
| Question or problem | What children are trying to explain or solve, in their words | An objective stated to the teacher, not to the class |
| Investigation or design | What children decide, do and record | A procedure supplied, so no decisions remain |
| Individual thinking | Private writing or drawing before any discussion | Straight to group talk, where the confident child sets the answer |
| Argument structure | Claim, evidence and reasoning, with the stems children use | A discussion with no form, which produces opinions |
| Discourse moves | Named teacher moves and where each occurs | The teacher will facilitate discussion |
| Competing explanation | A deliberate alternative for children to weigh | One explanation confirmed, which is not argument |
| Assessment of the practice | A transfer task and a description of reasoning at each level | A recall check that cannot measure a practice |
Protect the individual thinking phase. Two minutes of private writing before discussion changes who participates and gives you evidence from every child rather than from the four who speak.
Evidence craft when the subject is classroom talk
Discourse claims need support, and the research on classroom talk in science is substantial enough to draw on properly.
- Cite the research behind the discourse moves you name, rather than presenting them as teaching instincts.
- Quote the practice from the standards document with its code and match it to what children actually do.
- Verify the science, including the explanation children are expected to reach, since an incorrect target explanation invalidates the whole lesson.
- Include the actual language: stems, prompts and questions written out rather than described.
- Keep children anonymous and composite in any example of talk.
- APA throughout, including any published task you adapt.
Add a line about what your discussion cannot settle. Some questions cannot be resolved by the evidence a classroom can gather, and saying which part of the explanation rests on evidence children collected and which rests on authority is an honest move that graduate readers value. It also models something worth modelling, since scientists distinguish between what they have established and what they are taking from others, and children who hear a teacher make that distinction learn a habit that no amount of instruction about the scientific method will teach them.
What separates Competent from a returned lesson
Because each aspect is scored alone, returns tend to name a discussion with no structure or an assessment that could not measure the practice.
- Children write or draw individually before any group discussion.
- The argument has a stated form and the language children use is supplied.
- At least three teacher discourse moves are named and placed.
- A competing explanation is deliberately available.
- The assessment requires application to a new situation.
WGU marks work Competent or Not Competent rather than assigning letter grades, and performance assessment work can be revised and resubmitted without a grade penalty, so a return costs calendar time inside a six-month flat-rate term, where the courses you close set your effective cost per course.
Standing boundaries: proctored objective assessments are for preparation only and never for us to sit, credentials are never requested, and any classroom-based component of your course stays yours to complete.
Six mistakes that cost time in D679
- Planning discussion without a structure. Unstructured talk after an activity produces opinions rather than argument.
- Going straight to group talk. Without individual thinking first, the discussion records what the most confident child believes.
- Naming a practice without building it in. A practice listed in the standards section and absent from the tasks is the classic alignment gap.
- Offering one explanation. Argument requires an alternative worth weighing, even a constructed one.
- Assessing a practice with recall. Performance standards need transfer tasks, which take longer to write and are what the aspect wants.
- Getting the target explanation wrong. If the science at the end is inaccurate, everything before it was rehearsal for an error.
How support works on D679
Send the rubric out of your Course of Study, the task directions and the grade plus the phenomenon or design problem in scope. The draft returns aspect-mapped, with individual thinking built in before discussion, an argument structure with the actual stems, named discourse moves placed in the lesson, and an assessment that requires transfer.
If your Degree Plan lists the undergraduate code, work from D672. The graduate curriculum counterpart is D678, and building both around the same unit saves a substantial amount of preparation.

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.
