proximal similarity model

Konteks lain juga boleh dalam keadaan yang sama, populasi yang sama dan fenomena yang serupa

Credibility can be achieved by: 1)prolonged engagement with participicant 2) persistent observation in the field 3) the use of peer debriefers/peer researcher 4) triangulation 5) referential adequacy 6) member checks

Konteks lain mungkin dalam keadaan, populasi, situasi dan fenomena yang berbeza

thinking about different generalizability contexts and developing a theory about which contexts are more like our study and which are less so :

When the subject develop or change during the experiment as part of an ongoing process independent of the experimental treatment

sampling model

start by identifying the population you would like to generalize to

click to edit

draw a fair sample from that population and conduct your research with the sample.

automatically generalize your results back to the population

imagine several settings that have people who are more similar to the people in our study or people who are less similar.
