Abstract
Aims: Technical communication (TC) is increasingly central to vocational employability in digitally mediated workplaces. This study validated a Technical Communication Module (TCM) for Chinese vocational students by documenting TC learning-in-action through structured classroom observation and identifying enactment strengths and constraints that inform targeted module refinement.
Study Design: A quasi-experimental design embedded in a Design and Development Research framework.
Place and Duration of Study: A vocational college in Guangdong Province, China, during a six-week implementation period from mid-November to late December 2024.
Methodology: Two intact first-year cohorts participated (TCM group: n=52; comparison group: n=54). Both cohorts completed parallel pre-/post-test performance tasks to benchmark changes in TC performance. Classroom enactment evidence was collected during TCM sessions using a structured observation checklist comprising 16 indicators across engagement, motivation, collaboration, task completion, and reflective practices. Three trained observers independently rated behaviors on a five-point frequency scale and recorded field notes. Items were summarized using scale-anchored descriptive labels and interpreted alongside qualitative notes.
Results: Most indicators showed strong enactment, including active participation, feedback seeking, collaboration, output accuracy, and on-time task completion (means 4.67–5.00). Two areas were consistently weaker: effective use of advanced digital tools (mean 2.67) and reflective writing (mean 3.00), despite strong identification of improvement areas (mean 4.67).
Conclusion: The findings support TCM as a process-oriented approach to vocational TC instruction and point to practical refinements, stronger scaffolding for advanced digital-tool use, more structured analytic reflection, and lightweight workflow supports to enhance workplace-aligned transfer.
