Hey Holt ... where's the truth? My letter

"Take Your Students to New Heights with Discovery-Based Learning"

We all agree that students learn best when they are involved in the learning process. Research confirms what we know from our professional experiences — that discovery-based learning helps close the achievement gap...

No I do not agree.
Send me an email and I will send you my research.

I've analyzed achievement gap data over a twelve year period in Seattle and find that the achievement gap has constantly increased each year with the discovery-based learning advocated and practiced by the Seattle Schools.

I await your response and I will be happy to furnish you with data.

Studies which report gains from discovery-learning often have other factors operating that are ignored.

Read NMAP's recommendations about research.
