Instruction and Assessment in Engineering and Technology Education
This domain covers how the content is taught and how learning is measured: standards-aligned planning, assessment design, safety instruction, and the lab management that makes hands-on work productive. Items often present a scenario and ask what the teacher should do next.
Planning from the end
Backward design (Wiggins & McTighe) sets the sequence: identify desired results, determine acceptable evidence, then plan learning experiences. Objectives should name an observable verb (calculate, construct, justify) at the appropriate Bloom level; "understand" is not directly assessable.
Assessment types
- Formative: exit tickets, questioning, draft critiques, design-notebook checks-used to adjust instruction.
- Summative: unit tests, performance tasks, final products-used to certify learning.
- Performance assessment of design work needs an analytic rubric (problem definition, use of evidence, iteration, communication), shared with students in advance.
- Validity means the assessment measures the intended construct; reliability means consistent results across raters and occasions. Vague rubric descriptors undermine both.
- Item analysis: difficulty index p = proportion correct; discrimination compares high and low scorers. An item with p = 0.30 and discrimination near zero is probably miskeyed or measuring something unintended-not simply "too hard."
Safety instruction
Safety is taught, not assumed: demonstrate, practice under supervision, and require a passed safety test before independent machine use. Maintain supervision, machine guarding, safety data sheets, and training records; negligence requires duty, breach, causation, and injury.
Differentiation and access
IEP and 504 accommodations, English-learner supports (visual glossaries, sentence frames, paired verbal and written directions), and universal design for learning applied to lab tasks. Group projects need individual accountability so grades reflect individual learning.
Worked example
A class of 30 takes a 10-item quiz. Item 4 is answered correctly by 9 students (p = 0.30), but high scorers miss it as often as low scorers (discrimination near 0). The teacher's next step is to inspect the item and the lesson it covers, not reteach the whole unit: the pattern suggests a flawed item or a misconception shared across ability levels.
Traps that cost marks
Calling a test reliable because it is hard; grading group products without individual evidence; writing rubric criteria about neatness only; and treating a safety video as sufficient preparation for machine use.
