Self-efficacy is an important trait that factors into a teacher’s ability to effectively teach writing. Teacher’s self-efficacy in writing, however, has been widely ignored by the writing research community. This study developed a new instrument to measure a teachers’ writing self-efficacy and examined its psychometric properties. The Writing Self-Efficacy Instrument demonstrated factorial scor...

In this paper we discuss an estimator for average treatment effects known as the augmented inverse propensity weighted (AIPW). This estimator has attractive theoretical properties and only requires practitioners to do two things they are already comfortable with: (1) specify a binary regression model for the propensity score, and (2) specify a regression model for the outcome variable. After ex...

the difficulty of assessing the writing skill is well known. different testing facets seem to affect the result of assessing the writing skill. in addition to the writer’s ability, the topic of the writing task, and methods of rating may contribute to the writer’s score. in this study, 50 efl learners wrote four different types of writing tasks (convincing, describing, instructing, and explaini...

The score reliability of language performance tests has attracted increasing interest. Classical Test Theory cannot examine multiple sources of measurement error. Generalizability theory extends Classical Test Theory to provide a practical framework to identify and estimate multiple factors contributing to the total variance of measurement. Generalizability theory by using analysis of variance ...

Relations between reading and writing have been studied extensively but the less is known about the developmental nature of their interrelations. This study applied latent change score modeling to investigate longitudinal relations between reading and writing skills at the word, sentence and text levels. Latent change score models were used to compare unidirectional pathways (reading-to-writing...
