Title: Effects of app-based morphological training on word knowledge in primary school children
Abstract: The study tested the effectiveness of a morphological training program on children’s learning and retention of exposed words and morphologically related unexposed words compared with an active control condition. 717 Norwegian second graders were randomized to either a morphological (n = 366) or a mathematical training program (n = 351). Both programs lasted for 8 weeks and were delivered as self-contained apps in a classroom setting. Participants’ meaning-based knowledge (word comprehension and definitions) and code-based knowledge (word reading fluency and spelling) was measured at pretest, immediate posttest, and delayed posttest. Analyses showed lasting effects of the morphological training on meaning-based knowledge of exposed words and unexposed words containing trained morphemes, as well as code-based knowledge of exposed words. The results demonstrate that a brief morphological training program can produce lasting and educationally meaningful gains in students’ word knowledge.
