Data Across Participants
Jeff (participant 1).
Jeff, aged 9, was entering grade 4 at his local public school in the fall. The within phase
results for Jeff begin with the baseline phase. Jeff's baseline level is 3.3% problems solved
correctly, derived from Jeff's 0% performance on the first two probes coupled with one correctanswer on the final baseline probe. The final probe of the phase indicates a slight increase from
the first two probes, but there is not enough further data to indicate the trend of the line would
continue upwards independently of the intervention protocol.
