Abstract Despite the recent interest in discovering language teacher beliefs in general, L2 writing teachers’ beliefs remain almost an untouched area. Considering this gap, this study aims at developing and validating a sound and comprehensive inventory that can be used for exploring L2 instructors’ beliefs regarding the nature of L2 writing, teaching L2 writing, and assessing L2 writing. To do that, a total of 653 writing instructors were involved in this two-phase study. In the development phase, a 94-item inventory, Teachers’ English Writing Beliefs Inventory (TEWBI), was devised. The factor structure of the TEWBI was determined through Exploratory Factor Analysis with the participation of 311 writing instructors. The results reveal that the TEWBI has a reliability value with .94, resulting in 57 items under three sub-scales. The Validation phase aimed at validating the structure of the inventory and its subscales, recruiting another 342 writing instructors. The results reveal that the model fits the data well (e.g. the RMSEA with .044 (90 % CI = .042–.046)), indicating the TEWBI produces psychometrically reliable and valid scores. In light of these findings, the sub-constructs of the TEWBI are discussed, and implications for L2 writing research are provided.

英语写作教师信念清单的开发和验证

摘要 尽管最近人们普遍对发现语言教师的信念感兴趣，但 L2 写作教师的信念几乎仍然是一个未触及的领域。考虑到这一差距，本研究旨在开发和验证一个健全和全面的清单，可用于探索 L2 教师对 L2 写作性质的信念、教授 L2 写作和评估 L2 写作。为此，共有 653 名写作教师参与了这项两阶段研究。在开发阶段，设计了一个 94 项的清单，即教师的英语写作信念清单 (TEWBI)。TEWBI 的因子结构是通过探索性因子分析确定的，有 311 名写作教师参与。结果表明，TEWBI 的信度值为 0.94，在三个子量表下有 57 个项目。验证阶段旨在验证清单及其分量表的结构，另外招募了 342 名写作教师。结果表明该模型很好地拟合了数据（例如，RMSEA 为 0.044（90% CI = .042–.046）），表明 TEWBI 产生了心理测量学上可靠和有效的分数。根据这些发现，讨论了 TEWBI 的子结构，并提供了对 L2 写作研究的影响。
