In Introduction to Logic- Syllogistic Terminology, the notes focus on two parts: the terms of syllogism, and practice with examples of the syllogisms.  I found the examples and venn diagram models to be helpful, especially because I was confused at first on how to correctly decipher between the categorical propositions.

There are three main steps in order to evaluate the mood and figure of the categorical form. First, you must evaluate the conclusion in the form of “p if q”.  The subject of the conclusion is called the minor term, and the predicate of the conclusion is called the major term.  Secondly, you must out the syllogism into standard form, such as placing them in the categories of A, E, I, or O.  Also, you must label the major premiss with the letter “P” and minor premiss with the letter “S” to indicate the standard order.  A term that occurs in both premisses, but not in the conclusion, is labeled by the letter “M” for middle term.  After figuring out the form of the syllogism, you must evaluate the mood to come up with the figure, either I, II, III, or IV.  Lastly, you use venn diagram models to show whether or not a syllogism is valid or invalid.

This explanation on determining syllogisms was a great review and study packet for outside of the classroom.  Whenever I become confused while trying to evaluate the syllogisms, I will definitely refer back to these clear notes.
