ETA Sheldon Ruby decided to implement a reward system after being inspired by fellow ETA Meghan Cullinan’s ticket system during the Mid-Year Enrichment Conference in Jakarta. The students at Sisingamangaraja have all been excited about collecting as many stickers as possible so that they can earn candy, and eventually, a certificate for outstanding English class participation.

Sheldon Ruby is currently teaching at SMA Sisingamangaraja, Tanjungbalai, North Sumatra
