‘Goed onderwijs (…) voorkomt en verkleint achterstanden’, zo meldt het regeerakkoord van Rutte III. Dat moge zo zijn, maar het is hoog tijd om het achterstandenbeleid op een nieuwe leest te schoeien. Geluiden over dat dit beleid faalt klinken al jaren. Wij pleiten ervoor de gewichtenregeling te stoppen. https://didactiefonline.nl/blog/blonz/doorg...

We wanted to know if guided oral reading would be an effective remedy for low achieving readers in the lower grades. Guided oral reading implies that a student reads a text aloud while an experienced reader supervis...

Werts, Breland, Grandy, and Rock (1980) have analyzed the relationship between a direct and an indi rect measure of writing ability. Werts et al. assumed that the same true score underlies both measures and concluded that the test-retest reliability of the essay tests is biased due to correlated errors. The present analysis of their data shows that...
