key science skills Flashcards
aim
is a statement outlining the purpose of the investigation.
should be expressed as clearly and precisely as possible
research question
a question that a study or research, through its thesis or statement, aims to answer.
primary data
information collected directly from the source by the researcher for their own specific surface
independent variable
variable that is manipulated in order to measure its effect on the dependant variable
sound of balloon popping
reward
operationalised IV
defining how it will be manipulated or measured in the experiment.
dependant variable
the variable the researcher uses to observe and measure the effects of the IV
-physical response
-number if letters remembered
-ability to find object in classroom
operationalised DV
defining how it will be manipulated or measured in the experiment
-type of physiological response
-times trials
type of investigation method- self report
participants answer questions presented by the researcher
students record their response to balloon popping
abiity to answer how many letters
type of investigation method - observational study
involves collection of data by carefully watching and recording behaviour as it occurs without any intervention
teacher watching reaction to balloon popping
conclusion
a decision about the results obtained from research mean.
words are more easily remembered with acrostics
students were able to find object with reward system
students had a physiological reaction to balloon popping before habituation
control variables
is one that is considered to ave an effect on the dependant variable in the experiment so it needs to be held constantly to remove its potential effects.
-the room temperature
-making sure each student is distracted with a task
-each student had the same amount of letters to remember
