This study fulfils one cycle of design research that seeks to build a didactical model for the instruction of prime numbers and related mathematical ideas in accordance with the theoretical principles of Realistic Mathematics Education. Taking the context of online information security as a realistic starting point, the Primes in Context using Technology (PiC-T) instructional sequence was developed that supports learning trajectories connecting a series of fundamental mathematical ideas with the support of technological tools. In a two-week classroom teaching experiment, a PiC-T hypothetical learning trajectory was implemented using a mobile computer station with a class of 17 high-achieving middle school students in their classroom.In fact, most groups entered large numbers in the input box to factor, and their laptops seemed to have become frozen, when the computers were ... There were also a few students who did not want to wait and shut down their computer. Most ofanbsp;...
