Inductive Reasoning

  • A rule is made after observing or seeing several examples
  • Making a hypothese and forming a reasonable conclusion from examing a large amount of evidence

Example: observing blue jays building nests

Inductive Teaching
Learning through examples
Deductive Approach

Deductive Reasoning

  • Moves from assumption to conclusion
  • Moves from general to specific
  • Use of applying a rule to make a conclusion

Example: number of pounds x cost per pound

Instructional Software
