Mastery Learning ... earning back points on assignments
In order to receive this credit, you are to complete the following on a clean sheet of paper, stapled to the front of the original… 
1) State the new score you anticipate on the assignment.
2) Rewrite the original question.
3) Reflection:  Explain the mistakes you made or the misunderstanding you had when answering the question initially.  The reflections must be thoughtful, complete and concise.
4) Re-answer the question or re-work the problem, explaining your correct answer fully.  If the problem is mathematical, show all steps.
5) Repeat steps 2-4 for each question on which you wish to earn back points
The packet must be handed in on or before the third class meeting after the assignment was passed back to the class.

BioChemistry Essentials

Basic level of understanding includes …
  • Life uses energy to reorganize matter
  • Label key points on the pH scale
  • Macromolecules: recognize carbohydrates, lipids, proteins, nucleic acids and ATP
  • Identify enzymes as proteins
Proficient level of understanding includes all above, plus…
  • Understand the role charged particles or regions play in chemical reactions
  • Discuss the importance of water to sustaining life
  • Distinguish between processes (like combustion) that release all of the energy of organic matter very quickly and (cellular respiration and fermentation) processes that release energy slowly enough to be useful to cells/organisms
  • Recognize a diagram of ATP and ATP – ADP cycle
  • Celebrate ATP
  • Distinguish the dual functions of carbohydrates, lipids, proteins, nucleic acids
  • Recognize the building blocks of carbohydrates, lipids, proteins, nucleic acids

Practice of Science Essentials

Basic level of understanding includes …
  • Definition and construction of a testable hypothesis
  • Theory as explanation
  • Design of a controlled experiment
  • Distinguish dependent from independent variable in a controlled experiment
  • Qualities of reliable data

Proficient level of understanding includes all above, plus…
  • The perspective/gestalt of science research
  • The vital role of objective observation in collecting reliable data
  • Graphing: Independent and dependent variables on correct axes, labels & units, setting appropriate axis-scales
  • The utility of well-designed models
  • The 4 qualities of reliable research: replicable, falsifiable, precise, straightforward
  • Distinction between precision and accuracy


  • The most reliable theories are solidly supported by experimental results from 3+ branches of a science
  • Reliable science uses logic to analyze results and meticulously links cause and effect to describe observable relationships
  • It’s not a scientific theory if it can’t be modified or disproved by new results.  Anecdotes are valuable as observations, but cannot by themselves prove or disprove a theory
  • Occam’s razor:  All else being held equal, the simplest explanation is usually correct
  • Bias:  the natural human tendency to wish for desired outcomes, overcome by conducting experiments rigorously and analyzing results honestly
