What to be presented:
1) Describe the topic
2) Find article/research that employed experimental (population/procedure)
3) think of one the example ( eg using multimedia is better than using books in the classroom

Notes:
1) Pre test, IQ Test , eg eating icecream ( treatment)
2) Attempts to influence/manipulate variables
3) Best for testing hypothesis of cause and effect relationship
4) In education – use to test effects of various practices:
a. Teaching techniques

2) An attempt by researcher to maintain control over all factors that may affect the result of an experiment

B. Research that employed experimental:
1) Experimental research is commonly used in science such as sociology and psychology, physics, chemistry, biology and medicine etc
2) Research designs which use manipulation and controlled testing to understand causal processes. Generally one or more variables are manipulated to determine their effect on a dependent variable
