A New Approach When Comprehending the Order of Operations in Mathematics Instruction: Mnemoni

The aim of this research is to investigate the effect of the mnemonic device (when you get money you can quickly go on a vacation) over students’ success and to find out students’ solution strategies when solving problems requiring the use of order of operations rule. this research model mixes the results from a quasiexperimental pretest-posttest design with a control group and from clinical interviews to find out students` solution strategies when solving order of operation problems. results from the study illustrated that using mnemonic device in instruction is more effective on students’ success and the level of retention on the order of operations subject comparing to the regular classrooom activities. moreover it was found that experimental group mostly used mnemonic device when solving order of operation problems and control group only and partly used order of operation rules.
