Exploring the impact of pre-task grammar instruction on young learners' form-focused episodes: The Role of individual variables

This repository contains the anonymised dataset and fully reproducible R scripts associated with the article “Pre-task grammar instruction and individual differences in young EFL learners’ form-focused interaction” (under review in Vigo International Journal of Applied Linguistics). The materials document the analysis of the effects of pre-task grammar instruction (PTGI) on young Basque-Spanish EFL learners’ engagement (LRE production) with two morphosyntactic targets: 3rd person singular subject pronouns (HE/SHE) Present simple 3rd person singular agreement morpheme (3ps -s). The dataset includes anonymised pair-level data from two collaborative dictogloss tasks, individual difference measures (Flyers test for proficiency and MLAT-ES Part II for language-analytic ability), and combined summary scores used in the statistical analyses. It also contains the corresponding R scripts used for data cleaning, reliability analyses, and inferential statistics. Additionally, the dataset includes transcription examples illustrating the coding of learners’ collaborative dialogues, including representative form-focused episodes (LREs) related to one of the target structures (present simple -s). These excerpts serve purely scientific-reporting purposes and comply with the Ethics Committee protocol and parental-consent conditions, which prohibit any transfer or disclosure of identifiable recordings or full transcripts. All included materials have been fully anonymised in accordance with institutional and data-protection guidelines.本仓库收录与论文《任务前语法教学与青年英语作为外语学习者的形式聚焦互动中的个体差异》（已提交至《维戈国际应用语言学学报》(Vigo International Journal of Applied Linguistics)待审）相关的匿名化数据集，以及可完全复现的R脚本。 本材料旨在分析任务前语法教学（Pre-task Grammar Instruction, PTGI）对巴斯克语-西班牙语双语青年英语作为外语（English as a Foreign Language, EFL）学习者的参与度（即词汇语法修正序列（Lexical-grammatical Repair Episodes, LRE）产出）的影响，研究涉及两类形态句法目标结构： 1. 第三人称单数主语代词（HE/SHE） 2. 一般现在时第三人称单数一致性词缀（3ps -s）。 数据集包含两项合作听写任务的匿名配对层面数据、个体差异测量指标（语言熟练度采用剑桥少儿英语YLE Flyers水平测试（Flyers test）成绩，语言分析能力采用现代语言能力倾向测验西班牙语版（Modern Language Aptitude Test-Spanish, MLAT-ES）第二部分得分），以及统计分析所用的综合汇总评分。同时附带用于数据清洗、信度分析与推断性统计的对应R脚本。 此外，数据集还包含示例转录文本，用于展示学习者合作对话的编码流程，其中包含与其中一类目标结构（一般现在时-s词缀）相关的典型形式聚焦互动片段（LRE）。此类节选仅用于科学报告用途，且已符合伦理委员会审查流程与家长知情同意要求——该要求禁止传输或披露可识别的录音或完整转录文本。所有收录材料均已按照机构与数据保护准则完成匿名化处理。
