LANGUAGE! Live Field-Testing and Implementation Results

As part of the developmental process the Voyager Sopris Learning Research Team has summarized the results of the extensive field testing.

LANGUAGE! Live Field Test Data—LRS Lexile Bands

After just one semester of LANGUAGE! Live instruction, students demonstrated approximately two years of academic growth. With these gains, students are closing the achievement gap.

Findings: According to MetaMetrics, students in grades 6–8 should gain approximately two Lexiles per week of instruction. In just 16 weeks of instruction, students in LANGUAGE! Live demonstrated an average Lexile gain of 142.97 Lexiles—more than four times the expected gain for these students (Figure 1). Students in the lower Lexile bands achieved the greatest gains, as would be expected. Notably, students in the upper bands also demonstrated impressive gains. Except for students in the 301–400 Lexile band, all groups made gains beyond the standard error of measurement, indicating these averages represent true gains.
