‘Does It Work?’ Adapting Evidence-Based Practices to Teach Argumentative Writing

The current study examined the impact of adapting an evidence-based instructional approach to develop ninth-grade students’ argumentative writing and self-regulated strategy use. Following the Self-Regulated Strategy Development (SRSD) model, strategies to plan and write argumentative texts were implemented in two Portuguese classrooms. The model relies heavily on the use of mnemonic strategies to support instruction. Thus, incremental effects of using dual-coding mnemonics (i.e., visual and verbal mnemonics) were explored when implementing SRSD instruction. For the first group (n = 23), SRSD instruction included verbal and visual mnemonics; for the second group (n = 25), SRSD instruction included verbal mnemonics alone. Groups were compared with a control group (n= 25) receiving standard writing instruction.The following findings were significant: a) SRSD instruction increased writing quality, organising, and spontaneous planning; b) dual-coding mnemonics enhanced writing quality, development of ideas, organising, language clarity, and spontaneous planning; c) national exams completed 15 weeks after instruction reinforced the effectiveness of the adapted SRSD strategies. The process of culturally adapting and implementing SRSD instruction to teach argumentative writing will be discussed, including the potential incremental effects of adding visual mnemonics to the SRSD instructional routine.
