The document describes a study conducted on a local language curriculum project in Central Sulawesi, Indonesia. The project aimed to incorporate students' local languages into the school curriculum. Quantitative research was conducted comparing students' command of local language (Moma) syntax and reading comprehension to their skills in Indonesian. The results found that while Moma skills were lower, the difference was not large, around 17-27%. Monitoring also found increased local language vocabulary and use. The conclusion was that with more hours of local language instruction, skills would improve rapidly, and incorporating grammar instruction could further support reading comprehension gains.
