The sampling method described is cluster sampling, as the population is divided into clusters (classrooms) and one cluster is randomly selected to sample from. It is not simple random sampling because the sample is not selected from the entire population, but from a subset (classrooms). It is not nonprobability sampling because the sampling method is not based on subjective judgment or convenience. It is not stratified sampling because the population is not divided into strata based on certain characteristics. It is not convenience sampling because the sample is not selected based on ease of access or availability.
