Phys128A Logbook grading policy
I describe below the score breakdown that will be used in grading
logbooks. Each lab will be graded with a total score of 100 points.
- 10 points: Clear use of logbook as a record rather than an
after the fact report. This involves recording sufficient detail.
- 10 points: Introduction and Theory. You should include enough
explanation of what you are doing, and the ideas behind it, that
the logbook is sufficient to understand it.
However, this is not measured by length of text.
- 10 points: Explanation of setup, including diagrams or photos,
and apparatus descriptions.
- 10 points: Raw data, including tables and plots made while
collecting the data. These need to be complete and clear enough that
one can reconstruct what was done.
- 10 points: Distilled data, including tables and plots.
These need to be clear and well labelled and sufficient to support
your conclusions.
- 10 points: Calculation of results and uncertainties.
A complete description of how the calculations were made should be
included. If these calculations are automated, then only one example
needs to be included.
- 10 points: A discussion of potential systematic
uncertainties. You may not be able to quantify them all, but you
should list the effects that you have thought about.
You also needn't measure them all, but you should comment on how you
might measure them or improve the procedure in future measurements
to avoid them.
- 10 points: Conclusion. This needn't be long, and you don't have
to conclude that everything worked well. But, the conclusions must
be clear and supported.
- 20 points: Completion of procedures, questions and exercises
specified in the lab manual.
Note that your logbook will also be required to contain the following
details.
- Names of lab partners
- Dates and times of measurements and entries
- Everything must be legible even if it is crossed out as
"wrong".
- Contents, e.g., tables of data and plots, must be sufficiently
labelled for content and context.
