• Does not reduce teacher workload“Setting different work for each student is time consuming. Following up on the work is time consuming.”
• Slightly provides school data“The data isn’t consistent or reliable in many cases. Levels attributed to students vary widely to levels attributed to students from other highly rated independent programs”
• Does not improve teaching efficiency“It varies from student to student and thus isn’t efficient. A more able student will engage and progress more. A less able student is often disengaged by some content which is out of their ZPD by the fact it is auditory vs sight spellings- they feel defeated and are reluctant to engage. It also goes against how most vocabulary and spelling is taught. We show them the word, break down its parts, define its parts, understand its spelling, and then learn the word. Your program has a voice read it. It’s difficult for me to understand some of the words particularly as the student may have never encountered such a word before- even at their level- and then they fail and don’t want to do it. In some cases it makes them feel like it’s set for a young child and they feel like people believe they aren’t clever.”
• Does not build student knowledge“They like the arcade. No it doesn’t help knowledge- at least it hasn’t for any of my students. I drag them through it and they are disengaged most of the time reluctantly doing the tasks to avoid a sanction.”
