1.Experimental-Experience variations that are carefully measured/recorded. Control-Variable kept ocnstant, measuring/recording any changes
1 of 6
2 reasons for high reliability of lab experiments?
1.Original experimenter can specify steps so researchers can repeat 2.Very detatched, researcher manipulates variables and records results. Scientists personal feelings=no effect on outcome
2 of 6
3 positivist advantages of lab experiments?
1.Achieves main goal of reliability 2.Careful control over experimental conditions/detachment=reliable 3.Allows researcher to identify/measure patterns quantitatively/establish cause & effect
3 of 6
2 positivist disadvantages of lab experiments?
1.Often impossible/unethical to control all of the variables 2.Small scale means results may not be representative or generalisable
4 of 6
Interpretivists on lab experiments?
Reject them as it fails to achieve goal of validity. Artificial situation producing unnatural behaviour. Favour more naturalistic field experiments
5 of 6
3 practical problems with lab experiments?
1.Impossible to identify let alone control, all the variables that may influence childs ed achievement 2.Cant be used to study past 3.Usually only small samples. Difficult to investigate large scale social phenomena=reduce representativeness
