Abstract

Mandarin lexical tones are difficult for beginners from non-tonal language backgrounds because learners do not automatically treat pitch movement as a stable cue for word meaning. In Arabicspeaking classrooms, the key risk may surface in question framing (here, Mandarin ma yes/no questions). Interrogative prosody may increase cue competition for lexical pitch cues, so this is treated as a classroom stress test rather than a clean sentence-final rise manipulation. This teaching-focused article presents a classroom routine that uses a simple pitch-line display (a Praatbased pitch-contour display; hereafter, pitch-line display) to guide learners’ attention to contour shape and turning points. The visual support is based on Praat-derived F0 contours, with light display-level enhancement for readability (e.g., smoothing, redrawing, and adding labels and directional arrows). It functions as an instructional scaffold rather than automated feedback or an analytic tool. The article provides (a) design principles for building instructionally usable contour visuals, (b) a brief teacher-led micro-teaching script that links gesture and contour cues, and (c) a task progression that moves from isolated syllables to statement and yes/no question sentences. The final section offers practical reflections on common confusions, especially those involving rising cues in questions, and describes teacher moves that help learners re-focus on lexical tone cues. The goal is to offer classroom-ready materials that can be implemented within normal teaching time.

基于音高线显示的普通话声调听辨教学：材料设计与课堂反思

摘要

普通话声调对非声调语言背景的初学者常常很难。学习者往往不会把音高变化当作稳定的“词义线索”。在阿语课堂里，这个问题在疑问句语境中可能更突出。以普通话“吗”是非问句为例，句末上扬的疑问语调容易和词汇声调的音高线索发生竞争，学习者会更依赖“像不像问句”的感觉，而忽视词汇层面的声调信息。基于这一点，本文把疑问句语境当作课堂中的“压力测试”，而不是简单的句末上扬操控。

 

本文提出一套可直接嵌入课堂的例行教学流程，核心工具是一种简易的音高线显示（pitch-line display），用于引导学习者关注轮廓形状与转折点。该显示基于 Praat 提取的 F0 轮廓，并做了轻量的课堂化处理（如平滑、重绘，以及添加标签与方向箭头），目的在于支持教学，而不是提供自动反馈或技术分析。文章提供三部分可用材料：（ a）轮廓可视化材料的设计原则；（b）一段简短的教师主导微型教学脚本，用于把手势线索与轮廓线索连起来；（c）一个从单音节到陈述句与是非问句的任务递进序列。最后，本文结合课堂观察与反思，总结学习者常见混淆点，尤其是疑问句上扬线索导致的误判，并归纳教师在课堂中帮助学习者重新聚焦词汇声调线索的具体做法。本文的目标是提供一套低负担、可操作的声调听辨教学材料，便于在常规课时中使用。
