Protocol: Strategy instruction for improving short‐ and long‐term writing performance on secondary and upper‐secondary students: A systematic review

Abstract This is the protocol for a Campbell systematic review. The objectives are as follows. This review aims to investigate the effectiveness of all types of teacher‐delivered classroom‐based strategy instruction aimed at students in the general population (all students) including struggling students (with or at‐risk of academic difficulties) in ages 12–19 for increasing writing performance. The majority of previous reviews scoped all outcomes presented in the primary studies. This review will solely focus on covering three most common outcomes: story quality, story elements and word count/length.
