Biology 101 Fermentation Lab Exercise 9 Rubric for Instructors for SLO
Data Collection
The Purpose of this Assignment:
To assess students overall ability to use Scientific Methodology as applied to
collecting and analyzing experimental data in connection with Cellular Respiration as
a fundamental biological concept in General Biology I.
Outcome:
To assess students ability to successfully use several distinct skills to demonstrate
general knowledge of the scientific method and how to apply those skills to a key
biological concept.
Process:
Students will carry out a laboratory exercise in which they formulate a hypothesis, set
up an experiment in their Biology 101 labs, collect data from that experiment, and
successfully analyze their data. This exercise is standardized for all Biology 101
students and is included in our Biology 101 Laboratory Manual currently as Exercise
9 Fermentation.
The students will write a report based on this experiment and the report will be graded
and used as the Biology 101 (General Biology 1) performance measure for the
Student Learning Outcomes benchmark.
Rubric:
Overall Report Instructions
•
QUESTION OF THE LAB: WHAT EFFECT DOES THE TYPE OF SUGAR
HAVE ON THE RATE OF FERMENTATION OF YEAST?
•
Must be written out in paragraphs; Follow the template form for the headings
from General Report Exercise 2. No more than 2-3 pages (2 pages is likely).
Cover page is not necessary as this is a lab report not an essay for composition.
•
Must have the hypotheses stated in introduction. Hypothesis formation is part
of Skill 1.
•
Must have at least one table of data and one line graph. Use hypothesis test data
for the Data Analysis as part of Skill 3.
•
Math must be included in the written report if worksheets cannot be turned in
or in lieu of worksheets being included. Math to be included: The control and
experimental treatment statistical means, the standard deviation and halfdeviations, for the control and experimental treatment, and the hypothesis
statistical test for significance (as carried out in Exercise 2 General Report).
This is Skill 2.
•
For math grading: There will be 3 means, 3 standard deviations, 3 groups of
half standard deviations and that leaves one more general point there for a total
of 10 points) * we may have to adjust this later
•
Only Materials may be bulleted; Methods must be in paragraph form
•
DATA to be collected in lab if on campus. Data will be provided by the
instructor if class is Virtual/Online.
•
Specific skills to be graded for SLOs will be marked as such on the scoring
part of this rubric.
•
Only the total grade needs to be on D2L. The SLO data (the skills) will be
recorded for each student on an Excel Sheet. The template for that sheet will be
sent to you along with this rubric. The instructors will complete the excel sheet
grades for skills and total grade earned and send them to the 101 Course
Director by a specified time no later than the end of regular semester classes for
the lab section.
