Laura,
I think I have figured out what you are doing.
For each task (just consider task 1, ignore 2, 3), you start with an estimate of the work, 3 hours, and type that into the work column.
Then you estimate the duration, 1 week, and type that into the duration column. Do you input in weeks or days?
Then you decide who is going to do it so you assign Dave. If the task type is fixed units (default) and effort driven is off, Dave gets 0.6 hours of work/day
Then what do you do?
I would start with the duration, then assign the resource, by default that will be at assignment units = 100%, and then adjust the work to 3 hours in the task usage view, or the details lower pane, work menu.
