The heart of System 44
is adaptive software that delivers direct, explicit, research-based phonics instruction. In order to move students through the program as quickly as possible, students are placed in the appropriate level based on their performance on the Scholastic Phonics Inventory
(SPI). Once placed, students work independently in the software for 20 minutes, which is continuously and automatically collecting data on student performance and adjusting accordingly. Students then work 20 minutes for small group teacher instruction.
