Research on the effectiveness enhancement and path optimization of online public English teaching in higher vocational colleges: A survey based on three higher vocational institutions in Tai’an
高职公共英语线上教学效能提升与路径优化研究——基于泰安市3所高职院校的调查

摘要

随着数字化技术的快速迭代，教师数字素养已成为推动职业教育高质量发展的关键要素。本研究对泰安地区3所公办高职院校的英语教师进行问卷与访谈调研，研究采用“五轮滚动迭代”论证程序，依次开展教师深度访谈、学生学情基准测试、行动策略干预、动态反馈跟踪及显著性数据统计分析，揭示了当前高职公共英语线上教学中存在的技术整合表层化、教学互动浅层化、效能评价片面化等问题，研究引入TPACK理论框架，构建“五维驱动、三阶联动”教学优化模型，并在教学实践中进行系统性应用与验证。实证结果表明，优化路径不仅显著提升了学生的线上参与深度与学业成就（p<0.05），同时有效促进了教师数字化教学胜任力的发展。本文旨在通过系统化教学设计，为高职英语教育的数字化转型与高质量发展提供兼具学理价值与实践意义的参考方案。

Abstract

With the rapid iteration of digital technology, teachers' digital literacy has emerged as a core variable in the high-quality development of vocational education. This study conducted questionnaires and interviews with English teachers from three public higher vocational colleges in the Tai’an region. Through a “five-round rolling iteration” demonstration procedure—comprising in-depth teacher interviews, student learning baseline testing, action strategy intervention, dynamic feedback tracking, and data significance analysis—the research reveals critical issues in current online public English teaching, such as superficial technology integration, shallow instructional interaction, and one-sided effectiveness evaluation. By introducing the TPACK (Technological Pedagogical Content Knowledge) theoretical framework, this paper constructs a “Five-Dimensional Driving and Three-Stage Linking” teaching optimization model and implements comprehensive deep interventions in teaching practice. Empirical results demonstrate that the optimized path significantly improves students' online engagement depth and academic achievement (p < 0.05), while also showing positive effects in promoting teachers' digital teaching competency. This paper aims to provide a reference scheme with both academic value and practical significance for the intelligent governance and paradigm shift of English education in higher vocational colleges through systematic instructional design.
