This AT (Assessment Task) was built to gauge how well a learner has constructed working knowledge.
Working Knowledge is defined as ideas that are useful to professionals in a field. WK should be committed to memory. Example: A medical doctor should know the names of the common bones in the human body. Example: A carpenter should know that a sheet of plywood comes in a standard size of 4 feet by 8 feet.
The context of this AT is a junior level engineering fluid mechanics class.
The purpose of this AT is to gauge how well a students knows common mass units (kilogram, gram, slug, and pound-mass). Does a student know, for example, that 1.o slug of mass is equivalent to 32.2 pounds mass?
The conditions of this assessment are closed book, closed notes, and no calculator. Rationale: Working knowledge and simple estimates should be routine for the engineer.
The AT, shown below, is classified as medium level of challenge.
The feedback is shown below.
This AT was used on a final exam in a junior level engineering fluid mechanics class prior to implementation of the L4Doing Approach. The sample size was about 50 students and approximately 30% of the students were able to produce a correct answer.
I welcome any comments! Some questions I have.
- Is this a task that an engineer (or a student studying engineering) ought to be able to do?
- What do you like about how this AT was designed?
- What specific recommendations do you have for making this AT better?
