A Class Room Logic / Deductive and Inductive, with Special Application to the Science and Art of Teaching

(3) Concrete Examples illustrating Joint Method.

The problem: Too much whispering.

	Antecedents		Consequent
1.	Insufficient work,		Much whispering.
	Lack of interest,
	Seated near a friend.
2.	More work,		Much whispering.
	Lack of interest,
	Seated near a friend.
3.	More work,		Much whispering.
	More interest,
	Seated near a friend.
4.	More work,		Not much whispering.
	More interest,
	Not seated near friend.
5.	More work,		Not much whispering.
	Lack of interest,
	Not seated near friend.
6.	Insufficient work,		Not much whispering.
	Lack of interest,
	Not seated near friend.

From this it may be concluded that the undue amount of whispering is caused by seating particular friends near each other.

The problem: Poor recitations.

	Antecedents		Consequent
1.	Long lesson,		Poor recitation.
	Faulty assignment of lesson,
	Fear of teacher.
2.	Lesson made shorter,		Poor recitation.
	Faulty assignment,
	Fear of teacher.
3.	Lesson made shorter,		Poor recitation.
	A more careful assignment,
	Fear of teacher.
4.	Lesson made shorter,		Good recitation.
	A more careful assignment,
	Removal of fear of teacher.
5.	Lesson made shorter,		Good recitation.
	Faulty assignment,
	No fear of teacher.
6.	Lesson long,		Good recitation.
	Faulty assignment,
	No fear of teacher.

Fear of teacher is the cause of the poor recitation.

(4) Distinguishing features.

Being a combination of Agreement and Difference the Joint Method possesses the characteristics of each, though more or less modified. The distinguishing marks may be summarized as follows:
