结论

本研究表明，在研究方法课程中，“检索练习+同伴互评”相较“重复阅读”能够显著提升学习成效与学习投入。具体而言，干预组在期末测验上的优势达到中等效应量（d≈0.45，p<.05），与检索练习在不同学科和学习阶段中稳定提升长期保持与迁移的证据一致（Roediger & Karpicke, 2006；Dunlosky et al., 2013；Adesope, Trevisan, & Sundararajan, 2017）。同时，干预显著提高了学习投入（β=0.31，p<.01），而自我效能未见显著变化，提示学习成效的提升更可能经由行为与情境层面的投入机制发挥作用，而非短期内改变学习者的能力信念。开放性题目还显示，同伴反馈被认为“具体且有用”，这与以往关于高质量、可操作性反馈促进学习调节与绩效改进的研究相吻合（Hattie & Timperley, 2007；Liu & Carless, 2006）。值得关注的是，低起点学生在该组合策略下受益更大（交互p<.05），提示其在缩小学习差距方面具有潜力；这一发现与检索练习广泛适用于不同能力水平学习者的总体结论相容，但仍需进一步检验该交互模式的稳定性与边界条件（Rowland, 2014；Adesope et al., 2017）。

综合上述证据，我们主张在研究方法课程中常态化嵌入结构化的检索练习与同伴互评：以周期性、对齐目标的低风险测验促进提取与反馈循环，并通过明确评价标准与反馈训练提升同伴反馈的针对性与可操作性，从而在不显著增加教师负担的前提下，提升学习投入与终结性表现。鉴于本研究存在单校样本、干预期较短及同一教师实施等局限，结论的外部效度需谨慎解释。未来研究可在多校、多教师与更长随访期条件下复制本效应，分解检索与互评的独立与交互效应，考察学习投入在其中的中介作用，并进一步检验对低起点学生的差异化效益与所需支架。

结论

基于课堂观察与学业数据的综合分析，本研究确认了五年级科学课堂在高阶思维培养方面的关键症结：学生课堂话语比例偏低（22%）与教师提问以记忆性为主（约70%）共同构成了偏向低认知水平的课堂生态，其结果体现为推理题正确率显著落后于记忆题（45% vs. 82%）。这一发现与修订版布鲁姆认知目标分类所指出的“认知加工层级与任务需求相匹配”原则相吻合，提示当课堂提问与学习活动主要停留在回忆与理解层面时，学生难以获得足够的推理与解释性思维练习（Anderson & Krathwohl, 2001；Chin, 2007）。

行动试验表明，引入可视化引导单与分层提问四周后，两班在形成性检测中的推理题正确率由45%提升至58%与61%，同时学生自评显示参与度提高。该结果为“结构化支架+高水平提问”促进高阶思维提供了初步证据：可视化表征与图示化工具能够帮助学生外化与组织科学概念，降低表征转换负荷，进而支持基于证据的解释与推理（Nesbit & Adesope, 2006；Wood, Bruner, & Ross, 1976）；分层提问为学生提供由浅入深的认知攀升通道，有利于从记忆性回答过渡到分析、综合与论证性表达（Chin, 2007；Hattie, 2009）。同时，参与度的提升与学习成效的改善相一致，也与形成性评价与即时反馈促进学习的证据链条相契合（Black & Wiliam, 1998）。

尽管成效可见，推理题正确率在短期内仍未达到与记忆题相当的水平，提示高阶思维的稳定提升有赖于更持久的教学改变与更高质量的课堂互动结构。课堂观察中小组任务缺少角色分工的现象，可能限制了学生的探究性对话与协作推理深度；既有研究显示，明确化小组角色与相互依赖结构有助于提升互动质量与复杂任务中的学术探究（Johnson & Johnson, 1999）。综上，本研究提供了学校情境下以可视化支架与分层提问促进五年级科学高阶思维的可行性与有效性初步证据，揭示了从提问结构、课堂话语与协作结构入手调整教学，能够在较短周期内带来推理表现与学习投入的同步改善；后续需在更长周期与更完善的合作学习结构下巩固并扩大这一成效。

Conclusion

This randomized crossover trial provides convergent evidence that the timing of teacher feedback differentially influences key dimensions of EFL undergraduates’ argumentative writing. Immediate feedback yielded small-to-moderate advantages over delayed feedback for organization and argument quality (g≈0.38–0.42, p<.01), with effects amplified among lower-proficiency writers. No differences emerged for lexical diversity, and delayed feedback was associated with a modest reduction in perceived cognitive load (p=.047). No carryover effects were detected, increasing confidence that observed differences are attributable to feedback timing rather than sequence artifacts.

Taken together, these results indicate that immediate feedback more effectively supports higher-order composing processes central to argumentative writing—structuring ideas and substantiating claims—than delayed feedback. This pattern is consistent with feedback frameworks emphasizing the value of task-contingent, timely information for guiding learners about where they are, where they need to go, and how to close the gap (Hattie & Timperley, 2007; Shute, 2008). The absence of an effect on lexical diversity suggests that vocabulary-related outcomes may be less sensitive to feedback timing alone and may require targeted lexical instruction or extended exposure. The slight reduction in perceived cognitive load with delayed feedback aligns with cognitive load theory, which predicts that decoupling performance and evaluation can lower immediate processing demands (Sweller, Ayres, & Kalyuga, 2011). However, this load reduction did not translate into measurable improvements in the assessed writing dimensions within the intervention period.

Pedagogically, the findings support prioritizing immediate feedback during drafting or soon after submission when the instructional aim is to strengthen organization and argumentative rigor, especially for lower-proficiency students who appear most responsive to timely guidance. Delayed feedback can be strategically employed when managing learners’ perceived effort is paramount (e.g., high-stakes tasks) or when fostering reflection is a primary goal, but instructors should not expect comparable short-term gains in argumentative quality from delay alone. Designing feedback schedules that adapt timing to learner proficiency and task goals may optimize both performance and cognitive effort.

Methodologically, the randomized crossover design and absence of carryover effects bolster internal validity. Nonetheless, external validity is constrained by the single-institution context and brief prompts. Future research should examine whether these timing effects generalize across institutions, longer and more complex argumentative tasks, and extended time frames, and should test delayed posttests to evaluate durability and transfer. Work that models cognitive load as a mediator and that differentiates among feedback modalities could clarify mechanisms and boundary conditions.

In sum, immediate feedback confers a reliable advantage for the core qualities of EFL argumentative writing, with the largest benefits for lower-proficiency writers, whereas delayed feedback affords a modest reduction in perceived cognitive load without commensurate performance gains. A proficiency-sensitive, goal-aligned approach to feedback timing is warranted.
