This study examines the potential effectiveness of form-focused instruction (henceforth, FFI) in developing Jordanian EFL learners’ linguistic and pragmatic knowledge. Forty-seven college students of nursing were divided into two groups: an experimental group of twenty-seven students received FFI on grammatical structures (viz. the simple present, gerunds, modal auxiliaries, questions, the present perfect and conditionals type II) and speech acts (viz. apology, request, and suggestion) and a control group of twenty students taught per the guidelines of the prescribed textbook. The data were analyzed using descriptive statistics, Analysis of Covariance (ANCOVA), and Multivariate Analysis of Covariance (MANCOVA). The findings revealed that FFI positively affects students' linguistic and pragmatic knowledge, more so for pragmatic than linguistic knowledge. Several pedagogical implications and recommendations are put forth.

以形式为中心的教学真的有作用吗？约旦英语学习者在语言和实用知识获取方面的潜在效力

这项研究检验了形式导向的教学（以下简称FFI）在发展约旦英语学习者的语言和实用知识方面的潜在有效性。47名护理专业的大学生分为两组：一个实验组，由27名学生组成，他们接受了语法结构（即简单现在，动名词，模态助词，问题，现在的理想和条件式II型）和言语表达的FFI。行为（即道歉，要求和建议），并按照规定教科书的指导原则，由20名学生组成的对照组。使用描述性统计数据，协方差分析（ANCOVA）和协方差多元分析（MANCOVA）对数据进行了分析。研究结果表明，外国直接投资对学生的语言和实用知识有积极影响，务实而非语言知识更是如此。提出了一些教学意义和建议。
