This targeted worksheet provides essential practice for mastering CCSS.ELA-LITERACY.L.4.1.f, enabling students to recognize and correct run-on sentences, a foundational skill for clear and coherent writing. Research consistently shows that direct and explicit grammar instruction, particularly when integrated into the writing and revision process, leads to significant improvements in the overall quality of student writing (Fisher & Frey, 2014). By engaging with these structured tasks, students move beyond simple identification to active correction, building both the competence and confidence needed for grammatical automaticity. This focused exercise is a practical application of evidence-based strategies, ensuring that learners can effectively apply their understanding of sentence boundaries in their own compositions, a key indicator of writing proficiency according to the RAND AIRS 2024 report on effective literacy instruction. It's a vital step toward developing writers who can construct sentences with precision and clarity.
